Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RFSMAA4JCCDQ are identified based on strict electrical and mechanical parameter matching within the SMA connector category. The primary substitution criterion is the maintenance of core RF performance specifications: 50 Ohm impedance, SMA connector style, female socket configuration, panel mount through-hole solder termination, and maximum frequency rating of 26.5 GHz.

The identified substitute part, RFSMAA2JEGDQ, shares all critical electrical parameters and functional characteristics with the main part. The distinction between these parts is limited to the mounting flange configuration: the main part features a four-hole flange mount, while the substitute features a two-hole flange mount. This mechanical difference allows for application-specific panel mounting requirements while preserving RF performance, thermal characteristics, voltage rating, and mating cycle specifications.

Substitution is valid when the application permits the alternative flange hole count and mounting geometry. Both parts maintain identical impedance, frequency response, operating temperature range, voltage rating, and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

Both the RFSMAA4JCCDQ and RFSMAA2JEGDQ are Active products with full ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Selection between these parts is determined by panel mounting geometry requirements.

The RFSMAA4JCCDQ is specified when the application requires four-hole flange mounting. The RFSMAA2JEGDQ is specified when the application requires two-hole flange mounting. Both parts deliver identical RF performance, thermal stability, and electrical characteristics across the full operating range.

Component selection should be based on the mechanical mounting interface of the target application. Electrical and RF performance specifications are equivalent between both parts. Both parts maintain active inventory status and full compliance certifications.

Frequently Asked Questions (FAQ)

Q: What is the primary difference between RFSMAA4JCCDQ and RFSMAA2JEGDQ?

A: The primary difference is the flange mounting configuration. The RFSMAA4JCCDQ features a four-hole flange mount, while the RFSMAA2JEGDQ features a two-hole flange mount. All electrical, RF, and thermal specifications are identical.

Q: Are these parts electrically interchangeable?

A: Yes. Both parts maintain 50 Ohm impedance, identical frequency response to 26.5 GHz, matching voltage ratings of 335 V, and identical operating temperature ranges of -65°C to 165°C. Electrical interchangeability is confirmed.

Q: Can I substitute RFSMAA2JEGDQ for RFSMAA4JCCDQ in my application?

A: Substitution is valid only if the panel mounting interface accommodates a two-hole flange configuration. If the application requires four-hole mounting, substitution is not appropriate.

Q: Do both parts have the same solder termination specifications?

A: Yes. Both the RFSMAA4JCCDQ and RFSMAA2JEGDQ use solder termination for both center contact and shield, with identical material composition and thermal characteristics.

Q: Are both parts RoHS compliant?

A: Yes. Both parts are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Q: What is the maximum frequency rating for both connectors?

A: Both the RFSMAA4JCCDQ and RFSMAA2JEGDQ are rated to 26.5 GHz maximum frequency.

Q: How many mating cycles are specified for these connectors?

A: Both parts are rated for 500 mating cycles.
