Substitute Part Grouping Explanation

Substitution of the MMCX-LP-FHSB(40) is determined by strict equivalence across the following critical parameters:

Connector Interface Parameters: Connector style (MMCX), connector type (Plug, Male Pin), and impedance (50 Ohms) must remain identical to ensure mechanical and electrical compatibility with mating receptacles.

Termination Parameters: Contact termination (Solder) and shield termination (Crimp) must match to maintain assembly process compatibility and signal integrity.

Mechanical Configuration: Mounting type (Free Hanging/In-Line, Right Angle) and fastening type (Snap-On) must be preserved to ensure proper board integration and mechanical retention.

Electrical Performance: Frequency maximum (6 GHz) and number of ports (1) define the operational bandwidth and circuit topology compatibility.

Material and Environmental Specifications: Center contact material (Phosphor Bronze), body material (Brass), dielectric material (PTFE), operating temperature range (-55°C ~ 85°C), and mating cycle rating (500) establish reliability and environmental performance equivalence.

Compliance: RoHS compliance status and MSL rating (1) must align with manufacturing and storage requirements.

The MMCX-LP-066(40) meets all these criteria and is classified as a parametric equivalent.

Engineering Selection Recommendations

Both the MMCX-LP-FHSB(40) and MMCX-LP-066(40) are active products manufactured by Hirose Electric Co Ltd and carry RoHS compliance certification. All critical electrical, mechanical, and environmental parameters are identical, establishing full parametric equivalence for RF coaxial connector applications.

The MMCX-LP-066(40) includes supplementary packaging (heat shrink) not present in the MMCX-LP-FHSB(40). This difference does not affect electrical or mechanical compatibility but may influence assembly workflow and material handling procedures.

Selection between these parts should be based on supply availability, inventory status, and packaging requirements specific to the application assembly process.

Frequently Asked Questions (FAQ)

Q: Can MMCX-LP-066(40) be used as a direct replacement for MMCX-LP-FHSB(40)?
