Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RFSSMAA4JAAB are identified based on electrical and mechanical parameter equivalence within the SSMA connector family. The substitution logic is based on the following criteria:

Electrical Equivalence: All substitute parts maintain identical connector style (SSMA), connector type (Jack, Female Socket), impedance (50 Ohms), frequency capability (40 GHz maximum), operating temperature range (-65°C ~ 165°C), contact termination (Compression), shield termination (Screw), dielectric material (PTFE), and center contact material (Beryllium Copper).

Mechanical Equivalence: All substitute parts share panel mount configuration with flange mounting feature, threaded fastening type, stainless steel body material, and identical mating cycle rating (500 cycles).

Compliance Equivalence: All substitute parts maintain RoHS3 compliance and MSL Level 1 (Unlimited) moisture sensitivity rating.

Distinguishing Parameter: The primary difference among parts in this group is the mounting hole configuration. The RFSSMAA4JAAB features four-hole flange mounting, while the RFSSMAA2JEGA features two-hole flange mounting. The RFSSMAA4JCCA also features four-hole flange mounting. Voltage rating varies slightly between parts (335 V for RFSSMAA4JAAB and RFSSMAA4JCCA; 350 V for RFSSMAA2JEGA).

Parameter Comparison

Engineering Selection Recommendations

Selection among RFSSMAA4JAAB, RFSSMAA4JCCA, and RFSSMAA2JEGA is determined by panel mounting hole requirements and voltage rating specifications.

RFSSMAA4JAAB and RFSSMAA4JCCA are electrically and mechanically equivalent with four-hole flange mounting. Both parts are Active in product status and RoHS3 compliant. The RFSSMAA4JAAB carries 1077 pieces in current inventory, while RFSSMAA4JCCA carries 1026 pieces. Both support 335 V voltage rating and are suitable for applications requiring four-point mechanical fastening on panel installations.

RFSSMAA2JEGA provides equivalent electrical performance with two-hole flange mounting configuration. This part is Active in product status, RoHS3 compliant, and carries 978 pieces in current inventory. The RFSSMAA2JEGA supports a higher voltage rating of 350 V and is suitable for applications requiring two-point mechanical fastening on panel installations.

All three parts maintain identical RF performance characteristics, operating temperature range, and compliance certifications. Selection is based on mechanical mounting requirements and panel hole configuration availability in the target application.

Frequently Asked Questions (FAQ)
