MMCX-LR-PC-1(40) Equivalent & Substitute Parts

Part Overview

The MMCX-LR-PC-1(40) is an MMCX connector receptacle manufactured by Hirose Electric Co Ltd, designed for RF coaxial applications requiring 50 Ohm impedance. This female socket connector features right-angle through-hole mounting with solder termination for PCB integration. The part is currently active in production with 722 units in stock. Substitute parts are identified when equivalent electrical and mechanical parameters are maintained across the connector interface, enabling design flexibility and supply chain alternatives.

Substitute Part Grouping Explanation

Substitute parts for the MMCX-LR-PC-1(40) are qualified based on strict equivalence of the following parameters:

Connector Style: MMCX
Connector Type: Receptacle, Female Socket
Impedance: 50 Ohms
Mounting Type: Through Hole, Right Angle
Contact Termination: Solder
Shield Termination: Solder
Frequency - Max: 6 GHz
Fastening Type: Snap-On
Number of Ports: 1
Mating Cycles: 500

All identified substitute parts maintain these core electrical and mechanical specifications, ensuring functional compatibility at the connector interface. Variations in operating temperature range, voltage rating, RoHS compliance status, and REACH classification do not affect the primary substitution criteria but are documented for system-level design considerations.

Engineering Selection Recommendations

All three parts meet the core substitution criteria for MMCX receptacle applications at 50 Ohms with 6 GHz frequency capability. Selection between these parts should be based on system-level compliance requirements:

For applications requiring RoHS3 compliance, the MMCX-LR-PC-1(40) (Hirose) and 73028 (Pomona Electronics) are suitable options. The 0734151002 (Molex) is RoHS non-compliant and should be selected only when RoHS compliance is not a design requirement.

For applications subject to REACH regulations, the 73028 (Pomona Electronics) is REACH Unaffected, while both the MMCX-LR-PC-1(40) and 0734151002 are REACH Affected and require compliance documentation.

Operating temperature range varies across the three parts. The MMCX-LR-PC-1(40) operates from -55°C to 85°C, while both 0734151002 and 73028 extend to 165°C maximum. System thermal requirements should determine selection when operating temperatures exceed 85°C.

Frequently Asked Questions (FAQ)

Q: Can the 0734151002 (Molex) be used as a direct replacement for the MMCX-LR-PC-1(40) (Hirose)?

A: Yes, from a connector interface perspective. Both parts are MMCX receptacles with identical electrical and mechanical specifications: 50 Ohm impedance, 6 GHz frequency capability, through-hole right-angle mounting, and solder termination. However, the 0734151002 is RoHS non-compliant, which may restrict its use in applications subject to RoHS3 requirements.

Q: What is the difference between the MMCX-LR-PC-1(40) and 73028 in terms of compliance?

A: The MMCX-LR-PC-1(40) is ROHS3 Compliant and REACH Affected. The 73028 is ROHS3 Compliant and REACH Unaffected. Both meet RoHS3 standards. The REACH status difference indicates that 73028 does not contain substances of very high concern (SVHC) listed under REACH, while MMCX-LR-PC-1(40) may contain such substances and requires compliance documentation.

Q: Are there temperature limitations when substituting these parts?

A: Yes. The MMCX-LR-PC-1(40) operates from -55°C to 85°C. Both 0734151002 and 73028 operate from -55°C to 165°C (0734151002) and -65°C to 165°C (73028). If your application requires operation above 85°C, the MMCX-LR-PC-1(40) is not suitable, but either 0734151002 or 73028 can be used.

Q: Do all three parts have the same mating cycle rating?

A: Yes. All three parts are rated for 500 mating cycles, ensuring equivalent mechanical durability for connector engagement and disengagement operations.

Q: What packaging format is used for these parts?

A: All three parts are supplied in Bulk packaging, suitable for PCB assembly and integration into production workflows.
