Allen-Bradley 1761-CBL-HM02 HHP Cable | Replacement, Equivalent & Selection Guide
The Allen-Bradley 1761-CBL-HM02 is a Hand-Held Programmer (HHP) communication cable designed for use with Rockwell Automation MicroLogix 1000 series programmable logic controllers. It provides the physical interface between the HHP terminal and the MicroLogix controller’s DH-485 communication port, enabling on-site programming, monitoring, and diagnostics without a PC.
Selection Background
Industrial buyers frequently search for 1761-CBL-HM02 replacement or equivalent cables when the original unit is discontinued, damaged, or unavailable through standard distribution channels. Understanding which models are direct drop-in replacements versus functional equivalents — and which cross-brand substitutes require configuration changes — is critical to avoiding costly downtime. This guide consolidates that information to help you make a confident, spec-accurate sourcing decision.

Compatible Replacement & Equivalent Models
① Direct Drop-in Replacements
These models share identical connectors, pinout, and DH-485 signaling. No configuration changes required.
- 1761-CBL-HM02 (OEM restock / surplus stock) — Exact factory original
- Rockwell Automation authorized spare (same catalog number, different production batch)
Prerequisite: Verify cable length and connector condition before installation.
② Functional Equivalents
Same electrical function and protocol; minor physical differences (e.g., cable length, jacket color) that do not affect operation.
- Third-party HHP cables manufactured to 1761-CBL-HM02 pinout specification
- Custom-assembled DH-485 HHP cables with verified RJ45 + HHP connector wiring
Note: Confirm pinout diagram against Rockwell publication 1761-IN009 before use.
③ Cross-Brand Alternatives
These require verification of connector compatibility and may need adapter hardware.
- Generic RS-485 programming cables with RJ45 interface — require pinout verification
- USB-to-DH485 adapters (e.g., 1761-CBL-PM02 + USB converter) — PC-based alternative, not HHP-compatible
⚠ Cross-brand substitutes are not recommended for safety-critical or certified installations without engineering sign-off.
Why Choose the Original Model
- Precision Pinout: Factory-verified DH-485 wiring eliminates signal integrity risks common in third-party cables.
- Rockwell Certification: Fully tested and certified for use with MicroLogix 1000 — no compatibility guesswork.
- System Compatibility: Guaranteed interoperability with 1761-HHP-B30 and all MicroLogix 1000 variants.
- Technical Support: Backed by Rockwell Automation’s global support network and documentation library.
- Warranty Coverage: Original parts carry manufacturer warranty; third-party substitutes typically do not.
- Audit & Compliance: Original catalog number simplifies spare-parts documentation for ISO/IEC audits.
Typical Applications
- Discrete Manufacturing: On-machine HHP programming of MicroLogix 1000 controllers on assembly lines
- Food & Beverage: Hygienic-area PLC diagnostics where PC access is restricted
- Water Treatment: Remote pump station monitoring and parameter adjustment via HHP
- HVAC & Building Automation: Field commissioning of MicroLogix-based control panels
- OEM Machine Builders: Bundled with MicroLogix 1000 panels for end-user on-site programming
- Maintenance & Repair: Emergency fault diagnostics without laptop access in harsh environments
System Compatibility
- 1761-L10xxx / L16xxx / L20xxx / L32xxx — MicroLogix 1000 controller family (all variants)
- 1761-HHP-B30 — Hand-Held Programmer terminal (primary mating device)
- 1761-CBL-AM00 — DH-485 network cable (complementary communication cable)
- 1761-NET-AIC — Advanced Interface Converter for DH-485 network expansion
- RSLogix 500 / Studio 5000 — Compatible when used with appropriate PC-side adapter
Selection Guide
Answer these three questions to confirm the 1761-CBL-HM02 is the right cable for your application:
- Is your controller a MicroLogix 1000 (1761 series)? — If yes, this cable is the correct HHP interface. If you have a MicroLogix 1100/1200/1400, a different cable family is required.
- Are you using the 1761-HHP-B30 Hand-Held Programmer? — This cable is specifically designed for the HHP terminal. PC-based programming requires a different cable (e.g., 1761-CBL-PM02).
- Do you need a direct replacement or a functional equivalent? — If the installation is safety-rated or under warranty, specify OEM original. For non-critical spares, a verified functional equivalent may be acceptable.

Replacement & Compatibility FAQ
Q: What can replace the Allen-Bradley 1761-CBL-HM02?
A: The only guaranteed drop-in replacement is another OEM 1761-CBL-HM02. Third-party cables manufactured to the same DH-485 HHP pinout specification can serve as functional substitutes for non-critical applications, but must be verified against Rockwell’s wiring documentation before use.
Q: Is the 1761-CBL-HM02 compatible with MicroLogix 1100 or 1200 controllers?
A: No. The 1761-CBL-HM02 is specifically compatible with the MicroLogix 1000 (1761 series) and the 1761-HHP-B30 terminal. MicroLogix 1100/1200/1400 controllers use different communication ports and require different cable models.
Q: What is the equivalent cable for PC-based programming of MicroLogix 1000?
A: The PC-based equivalent for MicroLogix 1000 programming is the 1761-CBL-PM02 (RS-232 to DH-485) or a USB-to-serial adapter with the appropriate driver. These are not substitutes for the HHP cable — they serve a different interface (PC vs. hand-held terminal).
