Engineering Selection Recommendations
For Active Product Status Applications:
The Cinch Connectivity Solutions Trompeter UPL220 series connectors (UPL220-009, UPL220-025, UPL220-026) are designated as Active products and are suitable for new design implementations. These parts maintain full electrical and mechanical equivalence to the Amphenol RF 112950 across all specified parameters.
For Existing Design Continuity:
The Amphenol RF 031-70238 provides parametric equivalence to the 112950 but carries a Not For New Designs designation. This part is appropriate only for sustaining production of existing designs or replacement applications where the original part number is specified.
Cable Group Compatibility Considerations:
Selection between substitute parts depends on cable group requirements:
- Amphenol RF 112950 and 031-70238: AT&T 735, 735A, Belden 735A1
- Cinch UPL220-009: Belden 8218, YR23023, Essex 21-597
- Cinch UPL220-025: 734A
- Cinch UPL220-026: 735A
Packaging Format:
The Amphenol RF 112950 is supplied in bag packaging. All substitute parts are supplied in bulk packaging. Procurement processes must account for this packaging difference.
Compliance Status:
All listed parts maintain ROHS3 compliance and REACH Affected status, meeting current regulatory requirements for electronic component applications.
Frequently Asked Questions (FAQ)
Q: Can the Cinch UPL220-009 directly replace the Amphenol RF 112950 in all applications?
A: The UPL220-009 matches all electrical and mechanical specifications of the 112950. However, cable group compatibility differs. The UPL220-009 is specified for Belden 8218, YR23023, and Essex 21-597 cables, while the 112950 is specified for AT&T 735, 735A, and Belden 735A1 cables. Verify cable group compatibility for your specific application before substitution.
Q: Why is the Amphenol RF 031-70238 marked as Not For New Designs?
A: The 031-70238 carries a Not For New Designs designation from the manufacturer. This part is available for sustaining production of existing designs but should not be selected for new product development. For new designs, select from the Active status alternatives: Amphenol RF 112950 or Cinch UPL220 series parts.
Q: What is the difference between the Cinch UPL220-025 and UPL220-026?
A: Both parts are electrically and mechanically identical. The primary difference is cable group compatibility: UPL220-025 is specified for 734A cable group, while UPL220-026 is specified for 735A cable group. Select based on your cable group requirements.
Q: Does packaging format affect electrical performance?
A: No. The Amphenol RF 112950 is supplied in bag packaging while substitute parts are supplied in bulk packaging. Packaging format does not affect connector electrical or mechanical performance. Selection should be based on procurement and inventory management requirements.
Q: Are all listed parts RoHS3 compliant?
A: Yes. The Amphenol RF 112950, 031-70238, and all Cinch UPL220 series parts (UPL220-009, UPL220-025, UPL220-026) are ROHS3 compliant and REACH Affected, meeting current regulatory requirements.
Q: What is the mating cycle rating for substitute parts?
A: The Amphenol RF 112950 and 031-70238 specify 500 mating cycles. The Cinch UPL220 series parts do not provide mating cycle specifications in the available data. For applications requiring specific mating cycle performance, the Amphenol parts provide documented ratings.
Q: Can I use UPL220-026 as a substitute for the 112950 based on cable group compatibility?
A: Yes. The UPL220-026 is specified for 735A cable group, which matches one of the cable groups supported by the 112950 (AT&T 735A). All electrical and mechanical parameters are equivalent. The UPL220-026 is an Active product suitable for new designs.
