TE Connectivity AMP Connectors 1-1337444-0 BNC Coaxial Connector Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 1-1337444-0 is a BNC Connector Jack with female socket configuration, rated for 75 Ohms impedance and designed for free hanging (in-line) solder termination. This component is classified as obsolete, necessitating identification of active equivalent parts for continued system design and procurement. The connector operates across a frequency range up to 2 GHz and supports standard coaxial cable groups including RG-59B, RG-62A, RG-140, and RG-210. Locating suitable substitutes ensures design continuity and maintains electrical performance specifications in RF applications.

Substitute Part Grouping Explanation

Substitution of the obsolete TE Connectivity 1-1337444-0 is based on electrical and mechanical parameter equivalence. The substitute part 1-1337443-0 maintains identical specifications across all critical RF performance parameters: BNC connector style, female socket jack configuration, 75 Ohms impedance, solder contact termination, crimp shield termination, free hanging in-line mounting, bayonet lock fastening, 2 GHz maximum frequency, compatible cable groups (RG-59B, 62A, 140, 210), operating temperature range (-65°C to 165°C), 500 V voltage rating, 500 mating cycles, and 0.2 dB insertion loss.

The substitute part differs in the following non-critical parameters: body finish (nickel versus silver), center contact plating (gold versus silver), product status (active versus obsolete), packaging (bulk versus unspecified), and compliance certifications (RoHS compliant and REACH affected versus not applicable/vendor undefined). These differences do not affect electrical or mechanical compatibility in standard RF applications.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity 1-1337443-0 serves as the direct substitute for the obsolete 1-1337444-0 based on complete electrical and mechanical parameter equivalence. The substitute part is currently in active production status, ensuring long-term availability and supply chain continuity.

The substitute part carries RoHS compliance certification, making it suitable for applications subject to Restriction of Hazardous Substances regulations. The REACH affected status of the substitute part indicates compliance with European chemical safety requirements. These certifications provide regulatory advantages over the original part, which carries undefined compliance status.

The differences in body finish (nickel versus silver) and center contact plating (gold versus silver) do not affect RF performance, impedance characteristics, or mechanical compatibility. Both finishes provide adequate corrosion resistance and electrical conductivity for 75 Ohm coaxial applications operating up to 2 GHz. The gold plating on the substitute part's center contact offers enhanced contact reliability and resistance to oxidation in long-term storage and repeated mating cycles.

Selection of the 1-1337443-0 substitute is appropriate for new designs, redesigns of systems using the obsolete part, and applications requiring regulatory compliance documentation.

Frequently Asked Questions (FAQ)

Q: Can the 1-1337443-0 substitute be used as a direct replacement for the 1-1337444-0 in existing designs?

A: Yes. The substitute part maintains identical electrical and mechanical specifications across all RF performance parameters, including impedance, frequency response, termination methods, and mounting configuration. Direct substitution is supported without circuit modification.

Q: What is the significance of the different body finishes (silver versus nickel)?

A: Both finishes provide adequate corrosion protection and electrical conductivity for RF applications. The nickel finish on the substitute part offers equivalent performance to the silver finish on the original part. Finish selection does not affect connector impedance, insertion loss, or frequency response.

Q: Does the gold plating on the center contact of the substitute part affect compatibility?

A: No. Gold plating on the center contact improves contact reliability and oxidation resistance without affecting electrical performance. The substitute part maintains the same 75 Ohm impedance and 0.2 dB insertion loss as the original part.

Q: Are there packaging differences between the main part and substitute?

A: The main part packaging is unspecified, while the substitute part is supplied in bulk packaging. Both parts are identical in form, fit, and function. Packaging differences do not affect component performance or compatibility.

Q: What compliance advantages does the substitute part offer?

A: The substitute part carries RoHS compliance certification and REACH affected status, providing regulatory documentation for applications subject to European environmental and chemical safety requirements. The original part carries undefined compliance status.

Q: Is the substitute part suitable for applications requiring long-term availability?

A: Yes. The substitute part is in active production status, ensuring continued availability and supply chain support. The original part is obsolete and subject to inventory depletion.

Q: Do the electrical specifications remain identical between the main part and substitute?

A: Yes. Both parts maintain identical specifications for impedance (75 Ohms), frequency response (2 GHz maximum), insertion loss (0.2 dB), voltage rating (500 V), operating temperature range (-65°C to 165°C), and mating cycle rating (500 cycles).

Q: Are both parts compatible with the same cable groups?
