BNC-LR-PC(40) Equivalent & Substitute Parts

Part Overview

The BNC-LR-PC(40) is a BNC connector jack (female socket) manufactured by Hirose Electric Co Ltd, designed for 50-ohm coaxial RF applications. This right-angle, through-hole solder-mount connector operates at frequencies up to 4 GHz and is rated for -55°C to 85°C. The part is currently active in production with 18,966 units in stock. Equivalent parts are identified when manufacturers discontinue production, inventory becomes constrained, or design flexibility requires alternative sourcing from qualified manufacturers meeting identical electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitution eligibility for the BNC-LR-PC(40) is determined by strict equivalence across the following critical parameters:

• Connector Style & Type: Must be BNC jack (female socket)
• Impedance: Must be 50 ohms
• Mounting Configuration: Must be through-hole, right-angle solder mount
• Fastening Mechanism: Must use bayonet lock
• Frequency Rating: Must support 4 GHz maximum frequency
• Operating Temperature: Must cover -55°C to 85°C range
• Contact & Shield Termination: Must be solder-terminated
• Number of Ports: Must be single port (1)

The substitute part 413631-1 (TE Connectivity AMP Connectors) meets all critical electrical and mechanical parameters, enabling direct functional substitution in PCB-mounted RF coaxial applications.

Engineering Selection Recommendations

Primary Selection (BNC-LR-PC(40) - Hirose Electric)

The BNC-LR-PC(40) is the specified part and remains the preferred choice for new designs and production runs. It carries RoHS compliance certification and is rated for 5000 mating cycles, providing extended connector lifecycle in high-cycle applications. Current inventory of 18,966 units supports immediate procurement without lead-time constraints.

Substitute Selection (413631-1 - TE Connectivity)

The 413631-1 serves as a functional equivalent for applications where Hirose sourcing is unavailable or where design flexibility permits alternative manufacturers. This part meets all critical electrical and mechanical parameters for 50-ohm RF coaxial applications up to 4 GHz. However, the following differences require evaluation:

• RoHS Compliance: The 413631-1 is RoHS non-compliant and REACH-affected. Applications subject to RoHS or REACH regulatory requirements must use the BNC-LR-PC(40).
• Mating Cycle Rating: The 413631-1 is rated for 500 mating cycles versus 5000 for the primary part. Applications requiring frequent connector mating should prioritize the BNC-LR-PC(40).
• Dielectric Material: The 413631-1 uses polymethylpentene (PMP) instead of PTFE. Both materials are suitable for 50-ohm RF applications at the specified frequency and temperature ranges.
• Contact Plating: The 413631-1 features gold-plated center contacts versus silver plating on the primary part. Gold plating provides enhanced corrosion resistance in certain environmental conditions.

Frequently Asked Questions (FAQ)

Q: Can 413631-1 be used as a direct replacement for BNC-LR-PC(40) in production?

A: The 413631-1 is electrically and mechanically compatible for RF coaxial applications up to 4 GHz. However, regulatory compliance must be verified. If the application requires RoHS compliance, the BNC-LR-PC(40) is mandatory. If mating cycles exceed 500 in the application lifecycle, the BNC-LR-PC(40) is recommended.

Q: What is the difference between PTFE and PMP dielectric materials in BNC connectors?

A: Both PTFE and PMP are suitable dielectric materials for 50-ohm RF connectors operating at 4 GHz and below. The choice between them does not affect electrical performance within the specified operating parameters. Material selection is typically driven by manufacturing process, cost, and environmental considerations.

Q: Does the gold plating on 413631-1 affect RF performance compared to silver plating?

A: Contact plating material does not affect RF performance at 4 GHz for 50-ohm connectors. Both gold and silver plating provide adequate conductivity and corrosion resistance. Gold plating may offer superior performance in high-humidity or corrosive environments.

Q: Are both parts available in the same packaging format?

A: Yes, both BNC-LR-PC(40) and 413631-1 are supplied in tray packaging, enabling equivalent handling and storage procedures.

Q: What should be considered when switching from BNC-LR-PC(40) to 413631-1?

A: Verify RoHS and REACH compliance requirements for your application. Confirm that the 500 mating cycle rating of the 413631-1 is sufficient for your use case. Conduct electrical testing if the application operates at the upper frequency limit (4 GHz) or in temperature extremes (-55°C or 85°C).
