Substitute Part Grouping Explanation
Substitution of the Weidmüller 997225 is determined by strict equivalence in the following parameters:
- Position Configuration: 4 positions across 2 levels
- Pitch Spacing: 0.200" (5.08mm) center-to-center
- Mating Orientation: Horizontal with board alignment
- Mounting Method: Through-hole PCB mounting
- Wire Termination Type: Screw-based clamping mechanism
- Color: Black housing
- Compliance: RoHS Compliant status
The substitute part Weidmüller 1769100000 meets all these core parameters while maintaining active product status and expanded electrical specifications.

Engineering Selection Recommendations
The Weidmüller 1769100000 is the direct active equivalent for the obsolete 997225. Both components share identical mechanical and electrical interface specifications: 4-position configuration, 5.08mm pitch, horizontal board mounting, and through-hole termination.
The 1769100000 maintains full RoHS and REACH compliance, matching the regulatory status of the original part. The substitute provides documented electrical ratings (10 A, 300 V) and expanded material specifications (PA66 housing, tin-plated brass contacts) that were not specified in the original 997225 documentation.
For applications requiring the 997225, direct substitution with 1769100000 is supported without design modification, provided the application requirements fall within the specified electrical and temperature parameters of the active part.
Frequently Asked Questions (FAQ)
Q: Can the 1769100000 directly replace the 997225 without PCB redesign?
A: Yes. Both parts share identical pitch (5.08mm), position count (4), mating orientation (horizontal), and mounting method (through-hole). PCB footprints are compatible.
Q: What are the key differences between these parts?
A: The 997225 is obsolete with unspecified electrical ratings. The 1769100000 is active production with documented 10 A current, 300 V voltage, -20°C to 100°C operating range, and enhanced clamping mechanism (tension sleeve).
Q: Are there packaging differences?
A: The 997225 packaging is unspecified. The 1769100000 is supplied in bulk packaging. Verify packaging requirements for your procurement process.
Q: Do both parts meet the same compliance standards?
A: Yes. Both are RoHS Compliant, REACH Unaffected, and classified as EAR99 for export control purposes.
Q: What wire gauges are supported?
A: The 1769100000 accepts 12-24 AWG wire. The 997225 wire gauge specification was not documented.
