Engineering Selection Recommendations

RFSSMAA2JEGA serves as a direct parametric equivalent to RFSSMAA2JCED. Both connectors maintain identical electrical specifications, material composition, and mounting configuration with 2-hole flange mounting. Selection between these two parts depends on inventory availability and procurement lead times, as all functional parameters are equivalent.

RFSSMAA4JCCA provides electrical and material equivalence with a primary difference in mounting hole configuration. This part features a 4-hole flange mounting pattern compared to the 2-hole configuration of RFSSMAA2JCED. The voltage rating is 335 V versus 350 V on the main part. Selection of RFSSMAA4JCCA is appropriate when panel mounting requirements specify 4-hole flange attachment. All three parts maintain ROHS3 compliance and MSL Level 1 rating, confirming suitability for equivalent applications.

Frequently Asked Questions (FAQ)

Q: Can RFSSMAA2JEGA be used as a direct replacement for RFSSMAA2JCED?

A: Yes. RFSSMAA2JEGA maintains identical electrical specifications, material composition, operating temperature range, voltage rating, and 2-hole flange mounting configuration. The parts are functionally interchangeable.

Q: What is the primary difference between RFSSMAA2JCED and RFSSMAA4JCCA?

A: The primary difference is the mounting hole configuration. RFSSMAA2JCED features a 2-hole flange, while RFSSMAA4JCCA features a 4-hole flange. Additionally, RFSSMAA4JCCA has a voltage rating of 335 V compared to 350 V for RFSSMAA2JCED. All other electrical and material parameters remain equivalent.

Q: Are all three connectors rated for the same frequency range?

A: Yes. RFSSMAA2JCED, RFSSMAA2JEGA, and RFSSMAA4JCCA are all rated for maximum frequency operation up to 40 GHz.

Q: Do these connectors require special handling or storage?

A: All three parts carry Moisture Sensitivity Level 1 (Unlimited), indicating no special moisture control requirements during storage or handling.

Q: Which part should be selected if the panel design requires 4-hole mounting?

A: RFSSMAA4JCCA is the appropriate selection for applications requiring 4-hole flange mounting. The connector maintains equivalent electrical performance and material specifications for RF coaxial applications.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. RFSSMAA2JCED, RFSSMAA2JEGA, and RFSSMAA4JCCA are all ROHS3 compliant.
