CON-SMA-EDGE: SMA Connector Jack Female Socket 50 Ohms Board Edge End Launch Equivalent & Substitute Parts

Part Overview

The CON-SMA-EDGE is an SMA connector jack with female socket configuration, designed for 50 ohm coaxial applications requiring board edge end launch solder termination. Manufactured by RF Solutions, this connector operates at frequencies up to 18 GHz and is ROHS3 compliant. The part is currently active in production with 1102 pieces in stock.

Equivalent and substitute parts are identified when design requirements necessitate alternative sourcing due to inventory constraints, supply chain considerations, or when functionally identical connectors from different manufacturers meet the same electrical and mechanical specifications.

Engineering Selection Recommendations

All identified substitute parts are active products with ROHS3 compliance or RoHS compliance status. Selection among equivalent parts should be based on the following engineering criteria:

Compliance and Certification: All substitute parts carry EAR99 ECCN classification and HTSUS code 8536.69.4010, matching the original CON-SMA-EDGE specification. Parts designated as ROHS3 Compliant (142-0701-801, 142-0701-841, 142-0711-841, 142-0711-871, 142-0741-871, 2921-61493, 2921-61493-TD, 32K145-400L5) provide the highest level of environmental compliance alignment with the original part.

Inventory Availability: The Cinch Connectivity Solutions part 142-0701-841 offers the highest inventory level at 20558 pieces, followed by 142-0701-801 at 9111 pieces. These options provide supply chain stability for high-volume applications.

Operating Temperature Range: Cinch and Amphenol parts specify -65°C to 165°C operating temperature. The Rosenberger part 32K145-400L5 specifies -55°C to 155°C, representing a narrower operating window suitable for applications not requiring the full lower temperature specification.

Mating Cycle Rating: Cinch and Amphenol parts specify 500 mating cycles. The Rosenberger part 32K145-400L5 specifies 100 mating cycles, indicating lower mechanical durability for high-cycle applications.

Body Material Considerations: Cinch and Rosenberger parts use brass body material. Amphenol parts use stainless steel body material. Both materials are compatible with the specified gold plating and beryllium copper center contact.

Frequently Asked Questions (FAQ)

Q: Can 142-0701-841 directly replace CON-SMA-EDGE in my application?

A: Yes. The 142-0701-841 meets all mandatory electrical and mechanical parameters: SMA connector style, jack female socket configuration, 50 ohm impedance, board edge end launch mounting, solder termination, threaded fastening, and 18 GHz frequency capability. Both parts are ROHS3 compliant with identical ECCN and HTSUS classifications.

Q: What is the difference between Cinch parts (142-0701 series) and Amphenol parts (2921-61493)?

A: The primary difference is body material. Cinch parts use brass body material; Amphenol parts use stainless steel body material. Both materials are compatible with the gold plating and beryllium copper center contact. Amphenol parts specify 0.13 dB insertion loss. All other electrical and mechanical parameters are identical.

Q: Are the 142-0741 series parts (jack assemblies) equivalent to the connector-only CON-SMA-EDGE?

A: The 142-0741-841 and 142-0741-871 are jack assemblies that include additional components (end cap for 142-0741-841). While the core connector meets all substitution parameters, the assembly configuration may require design verification if the application specifies connector-only form factor.

Q: Why does the Rosenberger part 32K145-400L5 have lower mating cycle rating (100 versus 500)?

A: The Rosenberger part specifies 100 mating cycles compared to 500 cycles for Cinch and Amphenol parts. This represents a design difference in mechanical durability. Applications requiring frequent connector mating should prioritize parts with 500 mating cycle ratings.

Q: Are all substitute parts ROHS3 compliant?

A: Eight of ten substitute parts are ROHS3 compliant. The Cinch parts 142-0711-821 and 142-0741-841 are designated as RoHS Compliant without the "3" designation. For applications requiring ROHS3 certification, select from: 142-0701-801, 142-0701-841, 142-0711-841, 142-0711-871, 142-0741-871, 2921-61493, 2921-61493-TD, or 32K145-400L5.

Q: Can I use 2921-61493-TD instead of 2921-61493?

A: Yes. Both Amphenol parts are electrically and mechanically identical. The "-TD" designation indicates tape and reel packaging format. Selection between these parts depends on packaging and handling requirements for your manufacturing process.

Q: What is the significance of the base product numbers (142-0701, 142-0711, 142-0741, 2921-61)?

A: Base product numbers identify connector families within manufacturer product lines. Variations in the full part number (such as -801, -841, -871 suffixes) typically indicate differences in plating specifications, finish options, or packaging configurations. All variants within these families maintain core electrical and mechanical compatibility.

Q: Is the operating temperature range critical for substitution?

A: Operating temperature range does not disqualify substitution when the application operates within the specified limits. The Rosenberger part specifies -55°C to 155°C versus -65°C to 165°C for other parts. If your application requires operation below -55°C or above 155°C, the Rosenberger part is not suitable.
