Substitute Part Grouping Explanation

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

Connector Style & Type: MMCX Plug, Male Pin configuration
Electrical Characteristics: 50 Ohm impedance, maximum frequency 6 GHz
Termination Methods: Solder contact termination with crimp shield termination
Mechanical Configuration: Free-hanging (in-line), right-angle mounting with snap-on fastening
Material & Finish Specifications: Brass body with gold finish, phosphor bronze center contact with gold plating, PTFE dielectric
Environmental Ratings: Operating temperature range -55°C ~ 85°C, 500 mating cycles, MSL 1

The substitute part MMCX-LP-066(41) maintains identical specifications across all these parameters, with the primary distinction being product status (active versus obsolete) and RoHS compliance certification.

Engineering Selection Recommendations

The MMCX-LP-066(41) serves as the direct active equivalent to the obsolete MMCX-LP-FHSB. Both parts share identical electrical, mechanical, and material specifications, ensuring functional interchangeability in 50 Ohm MMCX coaxial connector applications.

The primary advantages of selecting MMCX-LP-066(41) are:

Product Status: Active part with ongoing manufacturer support and availability
RoHS Compliance: Meets RoHS regulatory requirements, whereas the original part does not
Inventory Availability: Higher stock levels support procurement continuity

For applications requiring RoHS compliance or long-term supply chain stability, MMCX-LP-066(41) is the appropriate selection. For legacy systems where RoHS non-compliance is not a constraint, both parts maintain identical performance characteristics.

Frequently Asked Questions (FAQ)

Q: Are MMCX-LP-FHSB and MMCX-LP-066(41) electrically interchangeable?

A: Yes. Both parts maintain identical 50 Ohm impedance, 6 GHz maximum frequency, and solder/crimp termination specifications. Electrical performance is equivalent across all RF parameters.

Q: What is the difference between these two parts?

A: The primary differences are product status (obsolete versus active), RoHS compliance certification, and packaging format. All functional and mechanical specifications are identical.

Q: Can MMCX-LP-066(41) be used as a direct replacement in existing designs?

A: Yes. The parts are mechanically and electrically equivalent. The right-angle, free-hanging mounting configuration, snap-on fastening, and solder termination are identical, allowing direct substitution in PCB and cable assembly applications.

Q: Why is RoHS compliance important for this connector?

A: RoHS compliance indicates the part meets restrictions on hazardous substances in electrical and electronic equipment. MMCX-LP-066(41) meets these regulatory requirements, while MMCX-LP-FHSB does not. Selection depends on application regulatory requirements.

Q: Are there packaging differences between these parts?

A: MMCX-LP-FHSB packaging is not specified in available data. MMCX-LP-066(41) is supplied in bulk packaging. Confirm packaging requirements with procurement specifications.

Q: What is the operating temperature range for both parts?

A: Both parts operate across -55°C to 85°C, supporting applications in industrial and commercial temperature environments.

Q: How many mating cycles are rated for these connectors?

A: Both parts are rated for 500 mating cycles, defining the expected mechanical durability for snap-on connection and disconnection operations.
