TE Connectivity AMP Connectors 413558-3 BNC Coaxial Connector Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 413558-3 is a BNC connector jack designed for 75-ohm coaxial RF applications. This component is a female socket connector with right-angle through-hole solder termination, rated for frequencies up to 2 GHz and operating temperatures from -55°C to 85°C. The part is currently classified as obsolete, necessitating identification of active equivalent and substitute components that maintain electrical and mechanical compatibility for PCB-based RF signal transmission applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 413558-3 is determined by strict equivalence across the following critical parameters: connector style (BNC), connector type (jack, female socket), impedance (75 ohms), mounting configuration (through hole, right angle), termination method (solder for both contact and shield), frequency rating (2 GHz maximum), operating temperature range (-55°C to 85°C), voltage rating (500 V), mating cycle rating (500), and fastening mechanism (bayonet lock).

The identified substitute parts maintain these core electrical and mechanical specifications. Variations in secondary parameters such as center contact material (beryllium copper versus phosphor bronze), body finish (nickel versus tin-lead), and dielectric material composition (PTFE/PMP versus PMP only) do not affect functional compatibility within the defined operating envelope. Product status transitions from obsolete to active availability represent the primary driver for substitution consideration.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts maintain full electrical and mechanical compatibility with the 413558-3 across all critical operating parameters. The primary distinction between available options is product status and compliance documentation.

1274127-1 is classified as active with REACH affected status, providing current manufacturing support and regulatory compliance documentation. This part incorporates phosphor bronze center contact material and PMP dielectric composition.

413558-2 is classified as active with vendor-undefined REACH status. This part maintains the original beryllium copper center contact material and tin-lead body finish, offering the closest material composition alignment to the obsolete 413558-3 while providing active product availability.

Both substitute parts operate within identical electrical specifications: 75-ohm impedance, 2 GHz maximum frequency, 500 V voltage rating, 500 mating cycles, and -55°C to 85°C operating temperature range. Selection between these options depends on supply chain requirements, compliance documentation needs, and material composition preferences for specific application environments.

Frequently Asked Questions (FAQ)

Q: Can 1274127-1 or 413558-2 be used as direct replacements for the obsolete 413558-3?

A: Both parts are direct functional equivalents. They maintain identical electrical specifications (75-ohm impedance, 2 GHz frequency rating, 500 V voltage rating), mechanical configuration (BNC jack, female socket, right-angle through-hole solder termination), and operating parameters (-55°C to 85°C temperature range, 500 mating cycles). PCB footprints and connector interface dimensions are identical.

Q: What are the material differences between the substitute parts?

A: The 1274127-1 uses phosphor bronze center contacts with PMP dielectric material. The 413558-2 uses beryllium copper center contacts with tin-lead body finish and PMP dielectric material. The 413558-3 original part used beryllium copper contacts with nickel body finish and PTFE/PMP dielectric material. These material variations do not affect electrical performance within the specified operating envelope.

Q: Are there compliance or regulatory differences between the substitute options?

A: Both substitute parts are RoHS non-compliant, matching the original 413558-3 classification. The 1274127-1 carries REACH affected status with documented compliance. The 413558-2 has vendor-undefined REACH status. Both parts carry EAR99 ECCN classification and identical HTSUS codes. MSL rating is 1 (unlimited) for all three parts.

Q: What is the inventory status for these substitute parts?

A: The 413558-3 (obsolete) has 685 pieces in stock. The 1274127-1 (active) has 908 pieces available. The 413558-2 (active) has 1016 pieces available. Active status parts provide ongoing manufacturing support and replenishment capability.

Q: Are the mating cycle ratings identical across all three parts?

A: Yes. All three parts are rated for 500 mating cycles, indicating equivalent mechanical durability and connector longevity under normal use conditions.

Q: Can these connectors be used interchangeably in existing PCB designs?

A: Yes. The through-hole right-angle solder termination configuration, bayonet lock fastening mechanism, and single-port design are identical across all three parts. No PCB layout modifications are required for substitution.
