Engineering Selection Recommendations

Primary Recommendation for Active Production:

The TE Connectivity 5413631-1 is the preferred substitute for the obsolete 414373-4. This part maintains identical electrical and mechanical specifications while offering ROHS3 compliance and REACH affected status. With 2230 pieces in inventory, it provides the highest stock availability among TE Connectivity alternatives.

Secondary Recommendation for Active Production:

The TE Connectivity 5414373-1 serves as an alternative active-status substitute from the same manufacturer. It maintains all critical parameters and offers ROHS3 compliance with REACH unaffected status. Inventory of 796 pieces supports ongoing production requirements.

Alternative Manufacturer Options:

For applications requiring extended operating temperature ranges or enhanced mating cycle performance, the following active-status alternatives are available:

Pomona Electronics 4788 or 4788#/BULK: Offers extended operating temperature range (-65°C to 165°C) and ROHS3 compliance. Suitable for applications requiring broader thermal performance.
Huber+Suhner 85_BNC-50-0-1/133_NE: Provides extended operating temperature range (-65°C to 165°C), 500 mating cycles, and ROHS3 compliance with REACH unaffected status.
Hirose Electric BNC-LR-PC(41): Offers enhanced mating cycle performance (1000 cycles) and RoHS compliance. Operating temperature range matches the original specification (-55°C to 85°C).
Molex 0731714230: Provides ROHS3 compliance as an alternative from a major connector manufacturer.
Winchester Interconnect 364M095: Offers extended operating temperature range (-40°C to 165°C) and 500 mating cycles.

Compliance Considerations:

The original 414373-4 is RoHS non-compliant. For new designs or applications requiring regulatory compliance, select from ROHS3 compliant alternatives: 5414373-1, 5413631-1, 4788, 4788#/BULK, 85_BNC-50-0-1/133_NE, or BNC-LR-PC(41).

Frequently Asked Questions (FAQ)

Q: Can I directly replace the 414373-4 with any of the listed substitutes?

A: Yes. All listed substitutes maintain the critical parameters: BNC connector style, female socket jack type, 50 ohms impedance, through-hole right-angle mounting, solder termination, bayonet lock fastening, 4 GHz frequency rating, and 500 volt rating. Variations in internal materials and finishes do not affect functional compatibility.

Q: What is the difference between TE Connectivity 414373-4 and 5414373-1?

A: The primary differences are product status and compliance. The 414373-4 is obsolete and RoHS non-compliant, while the 5414373-1 is active and ROHS3 compliant. The body finish differs (tin versus nickel), but electrical and mechanical performance remain equivalent.

Q: Why should I choose 5413631-1 over 414373-1?

A: The 5413631-1 offers ROHS3 compliance and REACH affected status, making it suitable for regulated applications. It also has the highest inventory availability (2230 pieces) among TE Connectivity alternatives. The 414373-1 remains RoHS non-compliant.

Q: Are there performance differences between TE Connectivity and alternative manufacturer parts?

A: All substitutes meet the core electrical specifications (50 ohms, 4 GHz, 500 V). Variations exist in center contact material (phosphor bronze, beryllium copper, brass), body material composition, and dielectric material. These variations do not affect performance within the specified operating parameters. Some alternatives offer extended operating temperature ranges or enhanced mating cycle ratings.

Q: What packaging options are available?

A: The original 414373-4 packaging is not specified. Substitute parts are available in bulk packaging. Pomona Electronics offers both standard (4788) and bulk (4788#/BULK) packaging options.

Q: Which substitute offers the best thermal performance?

A: The Pomona Electronics 4788, 4788#/BULK, and Huber+Suhner 85_BNC-50-0-1/133_NE offer extended operating temperature ranges (-65°C to 165°C) compared to the original specification (-55°C to 85°C).

Q: Which substitute offers the highest mating cycle rating?

A: The Hirose Electric BNC-LR-PC(41) provides 1000 mating cycles, compared to 500 cycles for the original part and most substitutes.

Q: Are all substitutes RoHS compliant?

A: No. The TE Connectivity 413631-2 and 414373-1 are not RoHS compliant. The 414373-4 is also non-compliant. For RoHS compliance, select from: 5414373-1, 5413631-1, 0731714230, 4788, 4788#/BULK, 85_BNC-50-0-1/133_NE, or BNC-LR-PC(41).

Q: Can I use these connectors in applications requiring REACH compliance?

A: REACH status varies by part. The 5413631-1 is REACH affected. The 5414373-1, 4788, 4788#/BULK, and 85_BNC-50-0-1/133_NE are REACH unaffected. The 414373-4, 413631-2, and 414373-1 have vendor undefined or unspecified REACH status.

Q: What is the insertion loss specification?

A: The original 414373-4 does not specify insertion loss. Among substitutes, only the Winchester Interconnect 364M095 provides an insertion loss specification of 0.20 dB.
