TE Connectivity AMP Connectors 1054874-1 Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 1054874-1 is a coaxial adapter connector designed for RF applications requiring SMA female-to-female jack conversion. This component functions as a bulkhead panel mount adapter with 50-ohm impedance, operating across frequencies up to 18 GHz. The part is classified as obsolete, necessitating identification of active equivalent alternatives to maintain supply chain continuity for applications currently utilizing this connector. Substitute parts must maintain identical electrical and mechanical specifications to ensure direct interchangeability without circuit redesign or performance degradation.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for coaxial RF adapter connectors is determined by strict equivalence across the following critical parameters:

Electrical Compatibility Parameters:

• Impedance: 50 Ohms (mandatory match)
• Frequency maximum: 18 GHz (minimum requirement)
• Center gender configuration: Female to Female (mandatory match)
• Adapter type: Jack to Jack (mandatory match)

Mechanical Compatibility Parameters:

• Mounting type: Panel Mount Bulkhead (mandatory match)
• Style: Straight (mandatory match)
• Fastening type: Threaded connections (mandatory match)
• Operating temperature range: -65°C to 165°C (mandatory match)
• Mating cycles: 500 (minimum requirement)

Material and Construction Parameters:

• Center contact material: Beryllium Copper (mandatory match)
• Dielectric material: PTFE (mandatory match)
• Center contact plating: Gold (mandatory match)

The Amphenol SV Microwave 1129-6279 satisfies all mandatory electrical and mechanical parameters, establishing direct substitution eligibility for the obsolete TE Connectivity AMP Connectors 1054874-1.

Frequently Asked Questions (FAQ)

Q: Can the Amphenol SV Microwave 1129-6279 directly replace the TE Connectivity AMP Connectors 1054874-1 without circuit modification?

A: Yes. The 1129-6279 maintains identical electrical specifications (50-ohm impedance, 18 GHz frequency maximum, female-to-female center gender) and mechanical configuration (bulkhead panel mount, straight style, threaded fastening). Direct substitution is supported without circuit redesign.

Q: What are the key electrical parameters that determine substitution eligibility?

A: Impedance (50 Ohms), frequency maximum (18 GHz), center gender configuration (female to female), and adapter type (jack to jack) are the primary electrical parameters. All substitute parts must match these specifications exactly.

Q: Are there mechanical differences between the original and substitute parts?

A: Both parts share identical mechanical specifications: panel mount bulkhead configuration, straight style, threaded fastening, and -65°C to 165°C operating temperature range. Mating cycle ratings are equivalent at 500 cycles.

Q: What is the significance of the packaging difference?

A: The original TE Connectivity 1054874-1 is supplied with connector hardware (1 connector, 1 lockwasher, 1 nut per unit). The Amphenol SV Microwave 1129-6279 is supplied in tray packaging without specified hardware inclusions. Verify hardware requirements for your application and source separately if needed.

Q: Do both parts meet current regulatory compliance standards?

A: Both parts are REACH-affected and classified as EAR99 for export control. The substitute achieves ROHS3 compliance, while the original meets RoHS compliance. Both share identical HTSUS classification (8536.69.4010).

Q: What is the material composition of the center contact and dielectric?

A: Both parts feature beryllium copper center contacts with gold plating and PTFE dielectric material. These specifications are identical between the original and substitute.

Q: Are there any frequency or temperature limitations when substituting?

A: No. Both parts operate identically across the full 18 GHz frequency range and -65°C to 165°C temperature range. No operational limitations exist for the substitute.
