Compatible Replacement & Equivalent Models
The following models are commonly evaluated as replacements or equivalents for the IC697CGR935. Compatibility depends on firmware version, backplane configuration, and application requirements — always verify before substitution.
- IC697CGR935E — Enhanced revision of IC697CGR935; direct drop-in replacement in most Series 90-70 racks
- IC697CPX935 — Standard (non-redundant) CPU; suitable if hot stand-by redundancy is not required
- IC697CPX928 — Lower-memory CPU option for cost-sensitive non-redundant applications
- IC697CGR772 — Earlier hot stand-by CPU; compatible with same backplane but with reduced memory
- IC697CGR935B / 935C / 935D — Revision variants; functionally equivalent with minor firmware differences
- PACSystems RX7i CPU (IC698CPE020/030) — Next-generation platform; requires rack and I/O migration but offers modern redundancy features
Note: Cross-referencing with OEM documentation or contacting Konmask technical support is recommended before finalizing any substitution.
Why Choose the Original Model
- Bumpless Failover: The IC697CGR935 provides seamless switchover to the stand-by CPU with zero process interruption — critical for continuous manufacturing and utilities.
- Proven Reliability: Decades of field deployment in power generation, oil & gas, and heavy industry validate its robustness.
- Native Series 90-70 Integration: No firmware adaptation or rack modification required — plug-and-play within existing Series 90-70 infrastructure.
- OEM Spare Parts Availability: Konmask maintains sourced stock of tested IC697CGR935 units to support legacy system maintenance.
- Lower Migration Risk: Retaining the original module avoids costly re-engineering, re-validation, and downtime associated with platform migration.

Selection Guide
Use the following criteria to determine whether the IC697CGR935 or an alternative is the right choice for your application:
- Redundancy Required? → If yes and existing rack is Series 90-70: IC697CGR935 is the primary choice. If migrating to a new platform: consider PACSystems RX7i with IC698CPE030.
- Redundancy Not Required? → IC697CPX935 or IC697CPX928 offer cost savings with the same backplane compatibility.
- Budget-Constrained Replacement? → IC697CGR772 (earlier revision) may be available at lower cost; verify memory requirements.
- Long-Term Support Horizon? → For systems planned beyond 5–10 years, evaluate PACSystems RX7i migration to ensure continued OEM support.
- Immediate Drop-In Replacement? → IC697CGR935E or same-series revision variants (B/C/D) are the safest options.

Replacement & Compatibility FAQ
Q: Can IC697CGR935E replace IC697CGR935 directly?
A: In most cases, yes. The “E” suffix denotes an enhanced revision with the same form, fit, and function. Verify firmware compatibility with your Proficy ME version before installation.
Q: Can I use IC697CPX935 instead of IC697CGR935?
A: The IC697CPX935 is a standard (non-redundant) CPU. It will operate in the same rack but does not support hot stand-by redundancy. Only use it if redundancy is not a system requirement.
Q: Is IC697CGR935 compatible with PACSystems RX7i racks?
A: No. The Series 90-70 and PACSystems RX7i use different backplane architectures. Migration requires new rack hardware and I/O modules.
Q: What is the difference between IC697CGR935 revisions (B, C, D, E)?
A: Revisions typically reflect firmware updates, minor hardware improvements, or component substitutions. Functionally equivalent for most applications; check GE release notes for specific changes.
Q: Does Konmask provide technical support for integration?
A: Yes. Our technical team can assist with compatibility verification, configuration guidance, and sourcing of associated modules. Contact us via email or phone.
