Substitute Part Grouping Explanation

Substitution eligibility for the PCB.SMAFSTJ.A.HT is determined by strict alignment of the following critical parameters:

• Connector Style: SMA
• Connector Type: Jack, Female Socket
• Impedance: 50 Ohms
• Mounting Type: Through Hole
• Contact Termination: Solder
• Shield Termination: Solder
• Frequency - Max: 12.4 GHz
• Fastening Type: Threaded
• Number of Ports: 1

The substitute part 32K153-400L5 manufactured by Rosenberger meets all these core electrical and mechanical requirements, confirming functional equivalence for RF coaxial connector applications. Both parts share identical connector topology, impedance characteristics, and frequency performance specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the PCB.SMAFSTJ.A.HT and 32K153-400L5 are active production parts with ROHS3 compliance and unlimited moisture sensitivity ratings, making them suitable for standard industrial and commercial RF applications. The Taoglas part carries 946 units in current inventory, while the Rosenberger substitute has 1645 units available. The Rosenberger part offers a higher voltage rating of 480 V compared to 335 V on the Taoglas part, and includes specified mating cycle data of 100 cycles. Selection between these parts should be based on inventory availability, lead time requirements, and application-specific voltage and mechanical durability needs.

Frequently Asked Questions (FAQ)

Q: Can the 32K153-400L5 be used as a direct replacement for PCB.SMAFSTJ.A.HT?

A: Yes. Both parts share identical connector style (SMA), type (Jack, Female Socket), impedance (50 Ohms), mounting method (Through Hole), termination type (Solder), and maximum frequency (12.4 GHz). They are functionally equivalent for RF coaxial connector applications.

Q: What are the differences between these two parts?

A: The primary differences are center contact material (Phosphor Bronze vs. Beryllium Copper), voltage rating (335 V vs. 480 V), operating temperature specification (not provided vs. -65°C ~ 165°C), mating cycles (not provided vs. 100), and REACH status (REACH Unaffected vs. REACH Affected). The Rosenberger part provides higher voltage capability and documented mechanical durability.
