Engineering Selection Recommendations
All substitute parts listed are active production components with ROHS3 compliance and MSL rating of 1 (Unlimited), matching the regulatory and environmental requirements of the primary Amphenol RF 252149B-10 part. Selection among equivalents should be based on:
Cinch Connectivity Solutions 133-3701-301 and 133-3701-311 maintain the full operating temperature range of -65°C ~ 165°C, identical to the Amphenol RF reference part, and are suitable for applications requiring extended low-temperature performance.
Rosenberger 29K203-400L5 and Huber+Suhner 85_MCX-50-0-16/111_NH operate within -55°C ~ 155°C, appropriate for standard commercial and industrial RF applications where the extended low-temperature capability of the Amphenol part is not required.
Radiall USA R113665000, R113665000W, and R113666000 operate within -55°C ~ 155°C and are available in higher inventory quantities, supporting high-volume production requirements and supply chain continuity.
All parts are REACH Affected or REACH Unaffected as specified, with EAR99 ECCN classification and matching HTSUS codes, ensuring consistent regulatory and trade compliance.
Frequently Asked Questions (FAQ)
Q: Can I substitute the Amphenol RF 252149B-10 with any of the listed equivalent parts?
A: Yes. All listed parts meet the core electrical and mechanical specifications: MCX jack, female socket, 50 ohms impedance, through-hole right-angle solder termination, 6 GHz maximum frequency, 500 mating cycles, and ROHS3 compliance. Functional interchangeability is assured within these parameters.
Q: What is the difference between the Cinch parts (133-3701-301 and 133-3701-311)?
A: Both Cinch parts are parametrically equivalent MCX connectors with identical electrical and mechanical specifications. The difference is in the base product number designation (133-3701) and packaging configuration (Bulk). Both maintain the full -65°C ~ 165°C operating temperature range.
Q: Why do some substitute parts have a narrower operating temperature range (-55°C ~ 155°C)?
A: The Rosenberger, Huber+Suhner, and Radiall parts operate within -55°C ~ 155°C, which is narrower than the Amphenol RF part (-65°C ~ 165°C). These parts are suitable for standard commercial and industrial applications. Use the Amphenol RF or Cinch parts if extended low-temperature operation below -55°C or high-temperature operation above 155°C is required.
Q: Are there packaging differences among the substitute parts?
A: Yes. Amphenol RF 252149B-10 is supplied in standard packaging. Cinch parts are supplied in Bulk packaging. Radiall R113665000W and R113666000 are supplied in Box packaging. Rosenberger and Huber+Suhner parts are supplied in Bulk packaging. Packaging does not affect electrical or mechanical performance; it reflects supplier logistics and inventory management practices.
Q: Which substitute part has the highest inventory availability?
A: Radiall USA R113665000 has the highest inventory at 2326 pieces. Cinch 133-3701-311 has 1375 pieces, and Amphenol RF 252149B-10 has 1104 pieces. Inventory levels support component selection based on supply chain requirements and lead time considerations.
Q: Do all parts have the same dielectric material?
A: Most parts use Polytetrafluoroethylene (PTFE). Huber+Suhner 85_MCX-50-0-16/111_NH uses a Perfluoroalkoxy (PFA) and PTFE blend. Both materials are compatible with 50 ohm impedance and 6 GHz frequency operation. The dielectric material variation does not affect functional interchangeability.
Q: Are all substitute parts REACH compliant?
A: All parts are either REACH Affected or REACH Unaffected as specified by manufacturer. Amphenol RF, Cinch, Rosenberger, and Radiall parts are REACH Affected. Huber+Suhner 85_MCX-50-0-16/111_NH is REACH Unaffected. All parts carry EAR99 ECCN classification and are suitable for standard commercial export.
