Substitute Part Grouping Explanation

Substitution of the TE Connectivity 1-1478403-0 with the Amphenol RF 031-71013-RFX is based on the following critical parameters that must align for functional equivalence:

Mandatory Matching Parameters:

• Connector Style: BNC (both parts)
• Connector Type: Plug, Male Pin (both parts)
• Impedance: 75 Ohms (both parts)
• Contact Termination: Solder (both parts)
• Mounting Type: Free Hanging (In-Line) (both parts)
• Fastening Type: Bayonet Lock (both parts)
• Voltage Rating: 500 V (both parts)
• Mating Cycles: 500 (both parts)
• Number of Ports: 1 (both parts)

The Amphenol RF 031-71013-RFX maintains electrical and mechanical compatibility through identical core specifications. Both connectors support solder termination, bayonet locking mechanisms, and equivalent voltage and mating cycle ratings. The substitute part accommodates an expanded cable group range and operates at higher maximum frequency (3 GHz versus 2 GHz), providing enhanced performance capability for legacy system integration.

Parameter Comparison

Engineering Selection Recommendations

The Amphenol RF 031-71013-RFX serves as a functional substitute for the obsolete TE Connectivity 1-1478403-0 based on matched electrical and mechanical specifications. Both connectors maintain identical impedance (75 ohms), voltage rating (500 V), mating cycles (500), and insertion loss (0.2 dB) characteristics. The substitute part is currently in active production status, ensuring long-term availability and supply chain continuity.

Compliance Considerations: Both parts maintain RoHS compliance status (TE Connectivity: RoHS Compliant; Amphenol RF: ROHS3 Compliant) and REACH affected designation. Both carry identical ECCN (EAR99) and HTSUS (8536.69.4010) classifications, supporting regulatory consistency in procurement and deployment.

Operational Constraints: The substitute part operates within a reduced temperature range (-40°C to 80°C) compared to the original part (-65°C to 165°C). Applications requiring operation below -40°C or above 80°C require evaluation against specific system thermal requirements. The Amphenol RF part supports higher maximum frequency operation (3 GHz versus 2 GHz), providing performance margin for RF applications.

Material and Termination Differences: The substitute employs crimp shield termination versus clamp termination on the original part. Gold plating on the center contact (Amphenol RF) provides enhanced corrosion resistance compared to silver plating (TE Connectivity). Dielectric material differs (POM Acetal versus PTFE), with implications for specific RF performance characteristics in high-frequency applications near the 2 GHz operating limit of the original specification.

Frequently Asked Questions (FAQ)

Q: Can the Amphenol RF 031-71013-RFX directly replace the TE Connectivity 1-1478403-0 in existing assemblies?

A: Direct mechanical and electrical replacement is supported for applications operating within the Amphenol RF part's temperature range (-40°C to 80°C) and frequency requirements up to 3 GHz. The bayonet lock fastening, 75-ohm impedance, and solder termination method are identical. Applications requiring the original part's extended temperature range (-65°C to 165°C) require thermal evaluation before substitution.

Q: What is the significance of the different shield termination methods (clamp versus crimp)?

A: The TE Connectivity original uses clamp-style shield termination, while the Amphenol RF substitute employs crimp termination. Both methods provide equivalent shielding effectiveness when properly assembled. Crimp termination requires appropriate tooling and assembly procedures specific to the Amphenol RF design. Existing assembly fixtures designed for clamp termination require modification or replacement.

Q: Are the cable group specifications compatible between these parts?

A: The TE Connectivity 1-1478403-0 supports RG-179B, 187A, and URM111 cable groups. The Amphenol RF 031-71013-RFX accommodates an expanded range including RG-179, 179A, 179B, 187, 187A, Belden 9221, and M17/94-RG179. The substitute part is compatible with all cable groups supported by the original part, with additional cable compatibility options available.

Q: What are the packaging differences between these parts?

A: The TE Connectivity part is supplied in unspecified packaging with 834 pieces in stock. The Amphenol RF substitute is supplied in bulk packaging with 1332 pieces in stock. The TE Connectivity part includes 3 pieces per connector (connector, clamp, contact), while the Amphenol RF part includes 4 pieces per connector (connector, contact, ferrule, sleeve). Assembly kit contents differ and require verification against specific assembly requirements.

Q: How do the contact plating materials affect performance?

A: The TE Connectivity original features silver-plated center contacts; the Amphenol RF substitute features gold-plated center contacts. Gold plating provides superior corrosion resistance and is suitable for long-term storage and high-reliability applications. Silver plating offers lower contact resistance but is more susceptible to oxidation. Both materials meet the 500-volt rating and 0.2 dB insertion loss specification.

Q: What is the impact of different dielectric materials on RF performance?

A: The TE Connectivity original uses PTFE (polytetrafluoroethylene) dielectric material; the Amphenol RF substitute uses POM (polyoxymethylene) acetal. PTFE provides superior high-frequency performance and lower dielectric loss, particularly beneficial for applications approaching 2 GHz. POM acetal offers adequate performance for the 3 GHz maximum frequency rating of the substitute part. Applications operating near the 2 GHz limit of the original specification should evaluate dielectric material impact on insertion loss and return loss.

Q: Are both parts suitable for RoHS-compliant applications?

A: Yes. The TE Connectivity 1-1478403-0 is RoHS Compliant. The Amphenol RF 031-71013-RFX is ROHS3 Compliant. Both parts meet current RoHS requirements and are suitable for RoHS-compliant system integration. REACH affected status is identical for both parts.
