Key Parameters

Substitute Part Grouping Explanation

Substitution of the MMCX-P-066(41) is determined by strict equivalence across the following critical parameters:

Connector interface specifications: MMCX connector style, plug male pin configuration, and snap-on fastening type must remain identical to ensure mechanical and electrical compatibility with mating receptacles.

Electrical characteristics: 50 Ohm impedance and 6 GHz maximum frequency rating must be maintained to preserve signal integrity in RF applications.

Termination methods: Solder contact termination and crimp shield termination are required for consistent assembly and performance.

Mechanical configuration: Free-hanging in-line mounting type ensures compatibility with existing cable and PCB layouts.

Material and environmental specifications: Brass body with gold finish, phosphor bronze center contact with gold plating, and PTFE dielectric ensure consistent electrical performance and environmental durability across the -55°C to 85°C operating range.

Compliance: RoHS compliance and MSL 1 rating must be maintained for regulatory and manufacturing requirements.

All three substitute parts meet these criteria and are classified as active products, providing viable alternatives to the obsolete MMCX-P-066(41).

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts—MMCX-P-066(40), MMCX-P-088(40), and MMCX-P-FHSB(40)—are classified as active products and maintain full parametric equivalence with the obsolete MMCX-P-066(41). Each substitute meets all electrical, mechanical, and environmental specifications required for direct replacement in RF coaxial connector applications.

Selection among the three active alternatives should be based on procurement availability and inventory status. MMCX-P-088(40) currently maintains the highest inventory level at 1099 pieces. MMCX-P-FHSB(40) provides 889 pieces in stock, while MMCX-P-066(40) offers 686 pieces. All three parts are supplied in bulk packaging and carry identical RoHS compliance and MSL ratings.

Frequently Asked Questions (FAQ)

Q: Can MMCX-P-066(40), MMCX-P-088(40), and MMCX-P-FHSB(40) be used interchangeably with MMCX-P-066(41)?

A: Yes. All three substitute parts maintain identical electrical, mechanical, and environmental specifications. The primary difference is product status: the original part is obsolete while all substitutes are active. Mechanical and electrical compatibility is preserved across all four part numbers.

Q: What determines compatibility between these MMCX connector plugs?

A: Compatibility is determined by MMCX connector style, male pin configuration, 50 Ohm impedance, solder contact termination, crimp shield termination, snap-on fastening, and free-hanging in-line mounting type. All four parts meet these requirements identically.

Q: Are there differences in packaging between the main part and substitutes?

A: The original MMCX-P-066(41) packaging specification is not provided. All three substitute parts are supplied in bulk packaging. Confirm packaging requirements with your procurement specification before finalizing part selection.

Q: Do all parts meet the same environmental and compliance standards?

A: Yes. All four parts are RoHS compliant, rated for -55°C to 85°C operating temperature, carry MSL 1 (unlimited) moisture sensitivity level, and support 500 mating cycles. Compliance and environmental ratings are identical across all part numbers.

Q: Which substitute part should be selected based on availability?

A: Selection should be based on inventory requirements and procurement lead time. MMCX-P-088(40) offers the highest current stock level, followed by MMCX-P-FHSB(40) and MMCX-P-066(40). Confirm current availability with your supplier before finalizing design documentation.
