Engineering Selection Recommendations

All substitute parts listed are functionally equivalent to the BNC-LR-PC-3(41) for RF coaxial connector applications. Selection among substitutes should be based on the following criteria:

RoHS Compliance Requirements: If RoHS compliance is mandatory, select from 4788 (ROHS3 Compliant), 5413631-1 (ROHS3 Compliant), or 85_BNC-50-0-1/133_NE (ROHS3 Compliant). The original BNC-LR-PC-3(41) is RoHS Compliant. Part 414373-1 is RoHS non-compliant and should not be used in applications requiring RoHS certification.

Operating Temperature Range: The BNC-LR-PC-3(41) operates from -55°C to 85°C. Parts 4788 and 85_BNC-50-0-1/133_NE offer extended temperature range (-65°C to 165°C), suitable for applications requiring broader thermal performance.

Mating Cycle Durability: The original part specifies 1000 mating cycles. Most substitutes are rated for 500 mating cycles. For applications requiring higher cycle durability, the BNC-LR-PC-3(41) is preferred.

Inventory Availability: Part 5413631-1 has the highest stock level (2230 units), followed by 4788 (1047 units) and 85_BNC-50-0-1/133_NE (870 units).

REACH Compliance: Part 5413631-1 is REACH Affected. Parts 4788 and 85_BNC-50-0-1/133_NE are REACH Unaffected. The original BNC-LR-PC-3(41) status is not specified.

Frequently Asked Questions (FAQ)

Q: Can I use any of these substitute parts as a direct replacement for the BNC-LR-PC-3(41)?

A: Yes. All listed substitute parts match the core electrical and mechanical specifications: BNC connector style, female socket jack, 50 Ohm impedance, through-hole right-angle mounting, solder termination, bayonet lock fastening, and 4 GHz maximum frequency. They are functionally equivalent for RF circuit applications.

Q: What is the difference between the substitute parts?

A: Substitute parts differ in body material composition, body finish, center contact material, and dielectric material. These variations do not affect electrical performance within the specified operating envelope. Differences also exist in operating temperature range, mating cycle ratings, RoHS compliance status, and REACH compliance status.

Q: Does the body material or finish affect connector performance?

A: Body material and finish do not affect the electrical performance or RF characteristics of the connector. The 50 Ohm impedance, frequency response, and signal integrity are determined by the dielectric material, center contact geometry, and shield design, which are consistent across all substitutes.

Q: Which substitute part should I choose if RoHS compliance is required?

A: Select 4788 (Pomona Electronics), 5413631-1 (TE Connectivity), or 85_BNC-50-0-1/133_NE (Huber+Suhner), all rated ROHS3 Compliant. Avoid 414373-1, which is RoHS non-compliant.

Q: Are there differences in dielectric material among the substitutes?

A: Yes. The original BNC-LR-PC-3(41) uses Polytetrafluoroethylene (PTFE). Substitute 414373-1 uses Polymethylpentene (PMP), 5413631-1 uses Polymethylpentene (PMP), and 85_BNC-50-0-1/133_NE uses both Perfluoroalkoxy (PFA) and Polytetrafluoroethylene (PTFE). All dielectric materials are suitable for RF applications at 4 GHz and below.

Q: What is the mating cycle difference, and does it matter?

A: The original BNC-LR-PC-3(41) is rated for 1000 mating cycles, while most substitutes are rated for 500 cycles. Mating cycles indicate connector durability under repeated connection and disconnection. For applications with frequent connector engagement, the original part offers higher durability. For static or infrequent connection applications, substitute parts are adequate.

Q: Can I mix different substitute parts in the same circuit board design?

A: Yes. All substitute parts are electrically and mechanically equivalent. Mixing different manufacturers or part numbers in the same design does not affect RF performance, provided all parts meet the specified 50 Ohm impedance, frequency, and termination requirements.

Q: What is the significance of the voltage rating difference?

A: The original BNC-LR-PC-3(41) does not specify a voltage rating. Substitute parts are rated at 500 V. This rating indicates the maximum voltage the connector can safely handle without electrical breakdown. For applications operating below 500 V, all parts are suitable. The voltage rating does not affect RF signal integrity at microwave frequencies.
