Substitute Part Grouping Explanation

Substitution eligibility for the EMPCB.MMCXFSTJ.A.HT is determined by strict equivalence across the following critical parameters:

• Connector Style: MMCX
• Connector Type: Jack, Female Socket
• Impedance: 50 Ohms
• Mounting Type: Board Edge, Cutout; Surface Mount
• Contact Termination: Solder
• Shield Termination: Solder
• Fastening Type: Snap-On
• Frequency - Max: 6 GHz
• Number of Ports: 1
• Dielectric Material: Polytetrafluoroethylene (PTFE)
• Body Material: Brass
• Body Finish: Gold
• Center Contact Plating: Gold
• Housing Color: Gold

All identified substitute parts meet these core electrical and mechanical specifications. Variations in parameters not listed above do not affect substitution eligibility for this product category.

Parameter Comparison

Engineering Selection Recommendations

All three parts are active products with ROHS3 compliance and MSL 1 rating. The primary distinction is REACH regulatory status: the Taoglas EMPCB.MMCXFSTJ.A.HT and Molex 0734150961 are REACH Unaffected, while the Samtec MMCX-J-P-H-ST-EM1 is REACH Affected. Applications subject to REACH restrictions should prioritize the Taoglas or Molex alternatives. The Samtec part offers a higher voltage rating of 335 V compared to 170 V for the other two parts, which may be advantageous in high-voltage applications. Inventory availability should also be considered: Molex 0734150961 has 7604 units in stock, Samtec MMCX-J-P-H-ST-EM1 has 5694 units, and Taoglas EMPCB.MMCXFSTJ.A.HT has 904 units.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0734150961 be used as a direct replacement for the Taoglas EMPCB.MMCXFSTJ.A.HT?

A: Yes. Both parts are parametrically equivalent across all critical electrical and mechanical specifications for MMCX Jack, Female Socket 50 Ohm board edge connectors. Both are ROHS3 compliant and REACH Unaffected.

Q: What is the difference between the Samtec MMCX-J-P-H-ST-EM1 and the other two parts?

A: The Samtec part has a higher voltage rating of 335 V versus 170 V for the Taoglas and Molex parts. Additionally, the Samtec part is REACH Affected, whereas the Taoglas and Molex parts are REACH Unaffected. All other electrical and mechanical parameters are equivalent.

Q: Are there differences in center contact material between these parts?

A: Yes. The Taoglas part uses Phosphor Bronze, while both the Molex and Samtec parts use Beryllium Copper. This material difference does not affect substitution eligibility for this connector category.

Q: Do operating temperature ranges affect substitution?

A: Operating temperature ranges are provided for the Molex part (-55°C ~ 165°C) and Samtec part (-65°C ~ 125°C), but not specified for the Taoglas part. These variations do not disqualify substitution eligibility based on the provided parameters.

Q: Are mating cycle ratings provided for all parts?

A: Mating cycle data is provided only for the Molex part (500 cycles). This information is not available for the Taoglas or Samtec parts and does not affect substitution classification.
