Compatible Replacement & Equivalent Models
The following models are commonly evaluated as replacements or equivalents for the IC693ACC302B. Compatibility must be verified against your specific CPU and baseplate revision before installation.
- IC693ACC302A — Earlier revision; functionally equivalent in most applications
- IC693ACC302 — Base revision; verify firmware compatibility with your CPU
- IC693ACC301 — Standard battery module for Series 90-30; lower capacity, suitable for shorter backup requirements
- IC693PWR321 — Power supply with integrated battery backup; alternative architecture for new system builds
- Third-party lithium battery packs — Must match 3.0 V output, connector pinout, and physical form factor; not recommended for safety-critical systems without OEM validation
⚠ Always cross-reference the CPU model (e.g., IC693CPU374, IC693CPU375) and baseplate revision when selecting a replacement battery module.

Selection Guide
- Step 1 — Identify your CPU: Confirm your Series 90-30 CPU part number from the nameplate or system documentation.
- Step 2 — Check battery status: Use the CPU’s Battery Low LED or Proficy ME diagnostics to confirm replacement is needed.
- Step 3 — Verify revision: IC693ACC302B (Rev B) is the current production revision. If installed before 2005, confirm baseplate compatibility.
- Step 4 — Evaluate alternatives: If unavailable, IC693ACC302A or IC693ACC302 are the closest functional equivalents. Third-party options require engineering sign-off.
- Step 5 — Quantity & lead time: For MRO stocking, maintain 2–4 units per system. Contact us for volume pricing.

Replacement & Compatibility FAQ
Q: Can I replace IC693ACC302B with IC693ACC302A?
A: Yes, in most cases. Both revisions are functionally equivalent. Verify connector and physical dimensions match your baseplate slot before installation.
Q: How do I know when the battery needs replacement?
A: The Series 90-30 CPU has a dedicated Battery Low LED indicator. Proficy Machine Edition will also generate a fault log entry when battery voltage drops below threshold.
Q: Can I hot-swap the battery module without losing the PLC program?
A: On most Series 90-30 CPUs, the program is stored in flash memory and is not lost during battery replacement. However, real-time clock data may reset. Consult your CPU user manual for hot-swap procedures.
Q: Is IC693ACC302B compatible with PACSystems RX3i?
A: No. The RX3i platform uses IC695ACC402. Do not interchange between platforms.
Q: Do you provide a Certificate of Conformance?
A: Yes. A CoC is available upon request for all orders. Contact us before placing your order if required for your procurement process.
