Engineering Selection Recommendations

Primary Recommendation: Amphenol RF 031-4803-75

The Amphenol RF 031-4803-75 is the appropriate substitute for the obsolete TE Connectivity 1-1478047-0. Selection rationale:

1. Product Status: The substitute maintains active product status, ensuring continued availability and manufacturer support. The original part's obsolete classification creates supply risk for ongoing production and field service requirements.

2. Compliance Certifications: Both parts meet equivalent regulatory standards. The substitute achieves ROHS3 compliance, representing current regulatory alignment. Both parts carry identical ECCN (EAR99) and HTSUS (8536.69.4010) classifications, confirming trade compliance equivalence.

3. Electrical and Mechanical Equivalence: All critical parameters match exactly, including impedance (75 Ohms), frequency rating (2 GHz), connector gender configuration (Female to Female), and mechanical mounting specifications (Panel Mount Bulkhead with Bayonet Lock).

4. Environmental and Reliability Ratings: Operating temperature range (-65°C ~ 165°C) and mating cycle rating (500 cycles) are identical, confirming equivalent performance under specified conditions.

5. Packaging Consistency: Both parts include identical package contents (3 pcs: 1 Connector, 1 Lockwasher, 1 Nut), ensuring no assembly or installation procedure modifications are required.

Frequently Asked Questions (FAQ)

Q: Can the Amphenol RF 031-4803-75 directly replace the TE Connectivity 1-1478047-0 in existing applications?

A: Yes. The substitute part maintains identical electrical specifications (75 Ohm impedance, 2 GHz maximum frequency), mechanical configuration (female-to-female BNC jack adapter, panel mount bulkhead), and fastening mechanism (bayonet lock).
