Compatible Replacement & Equivalent Models
The following models are commonly evaluated as replacements or equivalents for the SGMPH-04AAAP20. Always verify electrical and mechanical compatibility before substitution.
- YASKAWA SGMPH-04ACA21 — Same power class, absolute encoder variant; drop-in for systems requiring battery-backed position retention
- YASKAWA SGMJV-04ADA21 — SGMJV series 400W equivalent; smaller frame, higher inertia ratio
- YASKAWA SGMMV-04ADA21 — Ultra-compact 400W replacement for space-constrained retrofits
- Mitsubishi HF-KP43 — 400W cross-brand equivalent; requires drive-side parameter remapping
- Panasonic MSMF042L1U2M — 400W MSMF series; compatible flange dimensions, different connector pinout

Why Choose the Original Model
- Guaranteed compatibility with existing YASKAWA SGDH/SGDM servo drives — no parameter re-tuning required
- Proven reliability in high-cycle industrial environments (packaging, robotics, CNC)
- OEM traceability — original part numbers (802-5794C, N-2304-1-K00AA) ensure audit-ready procurement
- Consistent encoder resolution — maintains system positioning accuracy without recalibration
- Manufacturer warranty & support — full YASKAWA service network coverage
Typical Applications
- CNC machine tool axes (milling, turning, grinding)
- Industrial robot joint drives (SCARA, articulated arm)
- Semiconductor wafer handling and pick-and-place systems
- Packaging machinery (form-fill-seal, cartoning)
- Textile and printing machine feed axes
- Electronic assembly and SMT equipment
System Compatibility
The SGMPH-04AAAP20 is designed to pair with the following YASKAWA servo drive families:
- SGDH Series — Σ-II drives (SGDH-04AE, SGDH-04AE-OY)
- SGDM Series — Σ-II compact drives
- CACR Series — Legacy YASKAWA servo amplifiers
Encoder cable: CN2 connector, 15-pin incremental. Power cable: CN1 4-pin. Verify cable assembly part numbers (JZSP-CMP00-xx / JZSP-CSP00-xx) when ordering replacement cables.
Selection Guide
Use the following criteria to confirm the SGMPH-04AAAP20 is the correct model for your application:
- Power requirement: 400 W continuous rated output
- Supply voltage: 200 VAC 3-phase (not suitable for 100V single-phase systems)
- Encoder: Incremental (P20 suffix) — if absolute encoder is required, select SGMPH-04ACA21
- Shaft: Straight, no keyway (P20) — for keyed shaft, select P21 suffix variant
- Frame: 60 mm flange — confirm mounting hole pattern matches machine interface
- Drive pairing: Must match with SGDH-04AE or equivalent Σ-II drive
If your application requires higher inertia, absolute feedback, or a different frame size, contact our engineering team for a tailored recommendation.

Replacement & Compatibility FAQ
Q: Can I replace SGMPH-04AAAP20 with SGMPH-04ACA21?
A: Yes, with drive parameter adjustment. The ACA21 uses an absolute encoder; your SGDH drive must support absolute mode (battery backup required).
Q: Is the SGMPH-04AAAP20 compatible with Σ-V drives (SGDV series)?
A: Not directly. Σ-V drives use a different encoder protocol. A converter or re-wiring is required — not recommended for production environments.
Q: What is the difference between P20 and P21 shaft suffix?
A: P20 = straight shaft without keyway; P21 = straight shaft with keyway. Verify your coupling type before ordering.
Q: Do you supply matching servo cables for this motor?
A: Yes. Specify cable length (3m / 5m / 10m) when ordering. Compatible cable part numbers: JZSP-CMP00-03-E (encoder) and JZSP-CSP00-03-E (power).
Q: What is the lead time for SGMPH-04AAAP20?
A: Subject to stock availability. Contact us for real-time inventory status. Expedited sourcing available for urgent requirements.
