Engineering Selection Recommendations

Primary Substitute: C&K 301419100

The 301419100 is the qualified substitute for the obsolete 301429103. Selection of this substitute is based on:

1. Product Status Alignment: The 301419100 maintains active manufacturing status, ensuring long-term availability and supply chain continuity compared to the obsolete 301429103.

2. Compliance Certification: Both parts maintain MSL 1 rating. The substitute achieves ROHS3 compliance, which exceeds the baseline RoHS requirement of the original part, providing enhanced regulatory assurance.

3. Functional Compatibility: Identical thumbwheel actuator type and panel mount configuration ensure mechanical and operational compatibility in existing applications.

4. Electrical Performance: The specified contact rating of 0.1A @ 120VAC/28VDC and 100,000-cycle electrical life provide documented performance parameters for circuit design verification.

For applications where the original 301429103 is no longer available, the 301419100 provides equivalent functionality with improved product lifecycle support.

Frequently Asked Questions (FAQ)

Q: Why is the 301429103 being replaced?

A: The 301429103 has reached obsolete product status, meaning C&K has discontinued manufacturing and support. The 301419100 is an active product offering equivalent functionality with ongoing manufacturing support.

Q: Are the 301429103 and 301419100 mechanically interchangeable?

A: Both parts feature thumbwheel actuators and panel mount configurations. The 301419100 specifies screw-type panel mounting, which is compatible with standard panel cutout installations designed for the original part.

Q: What are the electrical differences between these parts?

A: The 301419100 provides documented electrical specifications: 0.1A @ 120VAC/28VDC contact rating and 100,000-cycle electrical life. The original 301429103 does not include published electrical parameters in the available documentation.

Q: Do both parts meet the same compliance standards?

A: Both parts maintain MSL 1 (Unlimited) moisture sensitivity rating. The 301419100 achieves ROHS3 compliance, which is a higher standard than the baseline RoHS compliance of the 301429103. The 301419100 also carries REACH Unaffected status.

Q: What is the operating temperature range for the substitute?

A: The 301419100 operates across -40°C to 65°C, providing a standard industrial temperature range suitable for most panel-mounted control applications.

Q: Are there packaging differences between these parts?

A: The 301419100 is supplied in bulk packaging. End caps are sold separately. Verify packaging requirements for your specific assembly process.

Q: What is the section width of the substitute part?

A: The 301419100 has a section width of 0.350 inches (8.89mm) and a depth behind flange of 48.11mm. Confirm these dimensions against your panel cutout specifications.
