Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Weidmüller 997242 is determined by strict alignment of the following critical parameters:

• Position Count & Level Configuration: 21 positions across 2 levels
• Pitch Specification: 0.200" (5.08mm) center-to-center spacing
• Mating Orientation: Horizontal with board alignment
• Mounting Technology: Through-hole PCB mounting
• Wire Termination Method: Screw-based clamping mechanism
• Regulatory Compliance: RoHS compliance and REACH unaffected status

The substitute part Weidmüller 1769040000 satisfies all mandatory substitution criteria. This part maintains identical positional architecture, pitch, orientation, and mounting methodology while offering active product status and enhanced electrical specifications.

Parameter Comparison

Engineering Selection Recommendations

The Weidmüller 1769040000 is a direct functional substitute for the obsolete 997242 terminal block. Both components maintain identical mechanical and electrical interface specifications, ensuring PCB layout compatibility and connector mating without design modification.

The substitute part offers active product status, providing assured long-term availability and supply chain continuity. Both components maintain equivalent regulatory compliance: RoHS compliant and REACH unaffected, with identical ECCN and HTSUS classifications.

The 1769040000 is supplied in bulk packaging and carries enhanced electrical specifications (15 A current, 300 V voltage) and defined operating temperature range (-50°C ~ 120°C), providing additional design margin and performance documentation compared to the main part.

Frequently Asked Questions (FAQ)

Q: Can the 1769040000 be used as a direct replacement for the 997242 in existing designs?

A: Yes. Both components share identical positional architecture (21 positions, 2 levels), pitch (5.08mm), mating orientation (horizontal with board), mounting method (through-hole), and wire termination technology (screw). PCB footprints are compatible without modification.

Q: What is the primary difference between these two parts?

A: The 997242 is obsolete; the 1769040000 is active. The substitute provides documented electrical ratings (15 A, 300 V), specified operating temperature range (-50°C ~ 120°C), and enhanced termination design (clamping yoke with tension sleeve). Housing color differs (black vs. orange).

Q: Are there packaging considerations when transitioning from 997242 to 1769040000?

A: The 997242 packaging specification is not provided. The 1769040000 is supplied in bulk packaging. Verify bulk packaging compatibility with receiving and assembly processes.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both components are RoHS compliant, REACH unaffected, and classified under identical ECCN (EAR99) and HTSUS (8536.90.4000) codes.

Q: What wire gauge range is supported by the substitute part?

A: The 1769040000 accommodates 14-24 AWG wire. The 997242 wire gauge specification is not provided in available documentation.
