Parameter Comparison

Engineering Selection Recommendations

Both the PCB.MMCXFSTJ.SMT.HT and MMCX-J-P-H-ST-SM1 maintain Active product status and are ROHS3 Compliant with MSL 1 (Unlimited) ratings, indicating equivalent reliability for storage and handling. Both components carry EAR99 ECCN classification and share identical HTSUS codes.

The Samtec MMCX-J-P-H-ST-SM1 substitute provides higher voltage rating (335 V versus 170 V) and specified operating temperature range (-65°C ~ 125°C), offering enhanced performance margins in applications requiring extended thermal or electrical specifications. The center contact material differs (Beryllium Copper versus Phosphor Bronze), which does not affect substitution eligibility as both materials satisfy the 50 Ohm impedance and solder termination requirements.

REACH compliance status differs between the two parts. The Taoglas component is REACH Unaffected, while the Samtec component is REACH Affected. This distinction may influence selection based on end-market regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can MMCX-J-P-H-ST-SM1 be used as a direct replacement for PCB.MMCXFSTJ.SMT.HT?

A: Yes. Both components share identical connector style, type, impedance, mounting configuration, termination method, and frequency rating. All critical substitution parameters align.

Q: What is the difference in center contact material between these parts?

A: The Taoglas part uses Phosphor Bronze while the Samtec part uses Beryllium Copper. Both materials are suitable for 50 Ohm solder-terminated MMCX connectors and do not affect functional compatibility.

Q: Why does the Samtec part have a higher voltage rating?

A: The voltage rating difference (335 V versus 170 V) reflects design specifications from each manufacturer. The Samtec component provides greater electrical margin for applications requiring higher voltage tolerance.

Q: Are there packaging differences between these parts?

A: Both components are supplied in Tray packaging. No packaging incompatibility exists.

Q: Does REACH compliance status affect substitution?

A: REACH compliance status is a regulatory consideration dependent on end-market and application requirements. The Taoglas part is REACH Unaffected while the Samtec part is REACH Affected. Selection should align with applicable regional regulations.

Q: What is the maximum operating frequency for both parts?

A: Both components are rated for 6 GHz maximum frequency, ensuring equivalent RF performance characteristics.
