Engineering Selection Recommendations

Primary Substitutes (TE Connectivity AMP Connectors):

The TE Connectivity 413631-2, 414373-1, 5413631-1, and 5414373-1 are direct functional equivalents manufactured by the same supplier. Among these, 5413631-1 and 5414373-1 are recommended for new designs due to ROHS3 compliance and active product status. The 413631-2 remains an acceptable alternative for legacy system support, though it carries "Not applicable" RoHS status. The 414373-1 offers equivalent performance with active status but maintains RoHS non-compliant designation.

Cross-Manufacturer Substitutes:

For applications requiring RoHS3 compliance and extended operating temperature ranges, the Pomona Electronics 4788 and 4788#/BULK provide active alternatives with operating temperatures from -65°C to 165°C. The Huber+Suhner 85_BNC-50-0-1/133_NE similarly offers ROHS3 compliance with extended temperature capability and 500 mating cycles. The Molex 0731714230 and Winchester Interconnect 364M095 provide additional cross-manufacturer options with active status.

Temperature-Extended Applications:

The Hirose Electric BNC-LR-PC(41) maintains the original operating temperature range (-55°C to 85°C) while offering enhanced mating cycle capability (1000 cycles versus 500) and RoHS compliance, making it suitable for high-cycle applications within the original thermal envelope.

Compliance Considerations:

For applications subject to RoHS3 requirements, select from: 5413631-1, 5414373-1, 0731714230, 4788, 4788#/BULK, 85_BNC-50-0-1/133_NE, or BNC-LR-PC(41). The original 413631-3 and 414373-1 are RoHS non-compliant and should be reserved for legacy system maintenance only.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 413631-2 directly replace the obsolete 413631-3?

A: Yes. The 413631-2 maintains identical electrical and mechanical specifications including 50-ohm impedance, 4 GHz frequency rating, 500-volt rating, through-hole right-angle mounting, and solder termination. The primary difference is packaging (bulk) and active product status. Dielectric material differs (PTFE versus PMP) and body finish is Tin-Lead versus Nickel, but these variations remain within acceptable substitution parameters.

Q: What is the difference between the TE Connectivity 5413631-1 and the original 413631-3?

A: The 5413631-1 is functionally equivalent with identical electrical specifications and operating temperature range. The key differences are product status (active versus obsolete), RoHS3 compliance (compliant versus non-compliant), and REACH status (affected versus undefined). The 5413631-1 is the recommended choice for new designs and RoHS-regulated applications.

Q: Are Pomona Electronics 4788 and 4788#/BULK interchangeable?

A: Yes. Both parts are identical in electrical and mechanical specifications. The designation 4788#/BULK indicates bulk packaging, while 4788 refers to the base part number. Both offer identical performance with -65°C to 165°C operating temperature range and ROHS3 compliance.

Q: Which substitute offers the widest operating temperature range?

A: The Pomona Electronics 4788, 4788#/BULK, and Huber+Suhner 85_BNC-50-0-1/133_NE all operate from -65°C to 165°C, providing the widest temperature envelope among available substitutes. The Winchester Interconnect 364M095 also operates to 165°C maximum.

Q: Does the Hirose Electric BNC-LR-PC(41) offer any performance advantages?

A: The BNC-LR-PC(41) maintains the original -55°C to 85°C operating temperature range while providing enhanced mating cycle capability (1000 cycles versus 500). It also carries RoHS compliance. This makes it suitable for high-cycle insertion applications within the original thermal specification.

Q: What dielectric material variations exist among substitutes?

A: Substitutes employ Polymethylpentene (PMP), Polytetrafluoroethylene (PTFE), Polypropylene (PP), or Perfluoroalkoxy (PFA) as dielectric materials. All maintain 50-ohm impedance and 4 GHz frequency rating. Material selection does not affect electrical compatibility for the specified frequency and impedance range.

Q: Are there inventory considerations for substitute selection?

A: Current inventory levels vary across substitutes. The 5413631-1 maintains the highest inventory (2230 pcs), followed by 364M095 (1001 pcs) and 4788#/BULK (1163 pcs). Inventory status should be verified at time of procurement, as availability may change.

Q: Which substitutes are suitable for RoHS-regulated applications?

A: The following substitutes carry RoHS3 compliance: 5413631-1, 5414373-1, 0731714230, 4788, 4788#/BULK, 85_BNC-50-0-1/133_NE, and BNC-LR-PC(41). The original 413631-3 and 414373-1 are RoHS non-compliant.

Q: Can substitutes with different center contact materials be used interchangeably?

A: Yes. Substitutes employ Beryllium Copper, Phosphor Bronze, or Brass as center contact materials. All maintain electrical compatibility at 50 ohms and 4 GHz. Material selection affects mechanical durability and mating cycle performance but does not alter RF electrical characteristics within the specified operating range.

Q: What is the significance of the 500 mating cycle rating?

A: The 500 mating cycle specification indicates the connector is rated for 500 insertion and withdrawal cycles before performance degradation. Substitutes meeting or exceeding this specification (such as the Hirose BNC-LR-PC(41) at 1000 cycles) provide equivalent or enhanced durability. Substitutes without specified mating cycle data should be evaluated for specific application requirements.
