Substitute Part Grouping Explanation

Substitution eligibility for the Weidmüller 997243 is determined by the following critical parameters:

• Positions and Levels: 22 positions per level, 2 levels total
• Pitch: 0.200" (5.08mm) spacing
• Mating Orientation: Horizontal with board configuration
• Mounting Type: Through-hole PCB mounting
• Wire Termination: Screw-based connection method
• Regulatory Compliance: RoHS compliance and REACH unaffected status

The substitute part Weidmüller 1769050000 satisfies all critical substitution criteria. This part maintains identical positional configuration, pitch, orientation, and mounting characteristics while offering active product status and enhanced electrical specifications.

Parameter Comparison

Engineering Selection Recommendations

The Weidmüller 1769050000 is a direct functional substitute for the obsolete 997243. Both components share identical mechanical and electrical interface specifications: 22-position configuration, 5.08mm pitch, horizontal board orientation, and through-hole mounting.

The 1769050000 offers the advantage of active product status, ensuring continued availability and manufacturing support. Both parts maintain RoHS compliance and REACH unaffected status, satisfying regulatory requirements for industrial applications.

The substitute part provides documented electrical specifications (15 A current, 300 V voltage) and defined operating temperature range (-50°C to 120°C), supporting design verification and thermal analysis. The Omnimate LM series designation indicates this component belongs to Weidmüller's established terminal block platform.

Frequently Asked Questions (FAQ)

Q: Can the 1769050000 directly replace the 997243 in existing PCB designs?

A: Yes. Both components share identical pitch (5.08mm), position count (22 per level), mating orientation (horizontal with board), and through-hole mounting footprint. PCB layout compatibility is maintained without modification.

Q: What is the primary reason for substitution?

A: The 997243 carries obsolete product status. The 1769050000 provides equivalent functionality with active manufacturing status and documented electrical specifications.

Q: Are there differences in wire termination between these parts?

A: Both use screw-based termination. The 1769050000 specifies clamping yoke and tension sleeve features with M2.5 screw thread and 0.4-0.5 Nm torque specification, providing enhanced termination documentation.

Q: Do both parts meet the same regulatory standards?

A: Yes. Both the 997243 and 1769050000 are RoHS compliant, REACH unaffected, and classified under ECCN EAR99 and HTSUS 8536.90.4000.

Q: What is the packaging difference?

A: The 997243 packaging is not specified. The 1769050000 is supplied in bulk packaging. Verify packaging requirements for your procurement process.

Q: Are there color or material differences?

A: The 997243 is black; the 1769050000 is orange. The 1769050000 uses thermoplastic Wemid housing material with copper alloy tin-plated contacts. Verify color coding requirements for your application.
