Substitute Part Grouping Explanation

Substitute parts for the RFSMAA4JCCHR are identified based on electrical and mechanical parameter equivalence within the SMA connector category. The primary substitution criterion is the maintenance of core RF performance specifications: 50 Ohm impedance, SMA connector style, jack female socket configuration, panel mount through-hole solder termination, and maximum frequency rating of 26.5 GHz.

The identified substitutes differ in a single mechanical parameter: the number of mounting holes in the flange pattern. The RFSMAA4JCCHR features a four-hole flange mount, while the RFSMAA2JEGDQ features a two-hole flange mount. Both RFSMAA4JCCHR and RFSMAA4JCCDQ share identical four-hole flange mounting configurations.

All substitute parts maintain the following critical parameters:

• Connector Style: SMA
• Connector Type: Jack, Female Socket
• Impedance: 50 Ohms
• Contact Termination: Solder
• Shield Termination: Solder
• Mounting Type: Panel Mount, Through Hole
• Frequency - Max: 26.5 GHz
• Operating Temperature: -65°C ~ 165°C
• Voltage Rating: 335 V
• Mating Cycles: 500
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Parameter Comparison

Engineering Selection Recommendations

The RFSMAA4JCCHR and RFSMAA4JCCDQ are direct equivalents with identical electrical and mechanical specifications, including four-hole flange mounting patterns. Both parts are active in production status and ROHS3 compliant. Selection between these two four-hole variants is based on inventory availability and procurement lead times.

The RFSMAA2JEGDQ provides electrical equivalence to the RFSMAA4JCCHR but features a two-hole flange mounting pattern instead of four holes. This part is suitable for applications where panel mounting geometry accommodates a two-hole configuration. The RFSMAA2JEGDQ maintains all critical RF performance parameters, operating temperature range, voltage rating, and compliance certifications.

Selection of any substitute part requires verification that the flange mounting hole pattern aligns with the mechanical design of the target application. All three parts are active products with current inventory availability.

Frequently Asked Questions (FAQ)

Q: Can RFSMAA4JCCHR be replaced with RFSMAA4JCCDQ?

A: Yes. Both parts are electrically and mechanically equivalent. They share identical SMA connector specifications, 50 Ohm impedance, frequency rating to 26.5 GHz, operating temperature range, voltage rating, and four-hole flange mounting configuration. Selection between them is based on inventory availability and procurement timing.

Q: What is the primary difference between RFSMAA4JCCHR and RFSMAA2JEGDQ?

A: The primary difference is the flange mounting hole pattern. RFSMAA4JCCHR features four mounting holes, while RFSMAA2JEGDQ features two mounting holes. All other electrical and mechanical parameters are identical, including impedance, frequency rating, operating temperature, and voltage rating.

Q: Can RFSMAA2JEGDQ be used in place of RFSMAA4JCCHR?

A: RFSMAA2JEGDQ is electrically equivalent to RFSMAA4JCCHR. However, substitution requires that the panel mounting design accommodates a two-hole flange pattern instead of four holes. RF performance and environmental specifications are maintained across both configurations.

Q: Are all three parts ROHS3 compliant?

A: Yes. RFSMAA4JCCHR, RFSMAA4JCCDQ, and RFSMAA2JEGDQ are all ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited).

Q: What is the maximum operating frequency for these connectors?

A: All three parts operate at frequencies up to 26.5 GHz with 50 Ohm impedance maintained across the frequency range.

Q: What is the operating temperature range for these SMA connectors?

A: All three parts operate across the temperature range of -65°C to 165°C.

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

A: All three parts are rated for 500 mating cycles.
