Substitute Part Grouping Explanation

Substitute parts for the MMCX-LP-088(40) are determined by strict equivalence across all critical electrical and mechanical parameters. The following parameters establish substitution eligibility:

Electrical Parameters: Connector style (MMCX), connector type (Plug, Male Pin), impedance (50 Ohms), frequency maximum (6 GHz), contact termination (Solder), and shield termination (Crimp).

Mechanical Parameters: Mounting type (Free Hanging/In-Line, Right Angle), fastening type (Snap-On), body material (Brass), body finish (Gold), center contact material (Phosphor Bronze), center contact plating (Gold), and dielectric material (PTFE).

Environmental Parameters: Operating temperature range (-55°C ~ 85°C), mating cycles (500), RoHS compliance, and MSL rating (1).

The substitute parts MMCX-LP-066(40) and MMCX-LP-FHSB(40) meet all these criteria and are therefore electrically and mechanically interchangeable with the MMCX-LP-088(40).

Engineering Selection Recommendations

All three parts—MMCX-LP-088(40), MMCX-LP-066(40), and MMCX-LP-FHSB(40)—maintain Active product status from Hirose Electric Co Ltd and carry RoHS compliance certification. Each part is rated for MSL 1, permitting unlimited shelf life under standard storage conditions. Selection among these equivalents may be based on inventory availability and packaging considerations. The MMCX-LP-066(40) includes supplementary components (1 connector and 1 heat shrink), while MMCX-LP-088(40) and MMCX-LP-FHSB(40) are supplied without additional accessories. All parts are suitable for direct substitution in applications requiring MMCX male plug connectors with 50 Ohm impedance, solder termination, and operation to 6 GHz.

Frequently Asked Questions (FAQ)

Q: Are MMCX-LP-088(40), MMCX-LP-066(40), and MMCX-LP-FHSB(40) electrically interchangeable?

A: Yes. All three parts share identical electrical specifications: 50 Ohm impedance, 6 GHz maximum frequency, solder contact termination, and crimp shield termination. They are electrically equivalent for RF coaxial applications.

Q: Are these parts mechanically interchangeable?

A: Yes. All three parts feature identical mechanical configurations: MMCX connector style, male pin plug type, free-hanging right-angle mounting, snap-on fastening, and identical material specifications (brass body with gold finish, phosphor bronze center contact with gold plating, PTFE dielectric).

Q: What is the difference between MMCX-LP-088(40) and MMCX-LP-066(40)?

A: The primary difference is packaging. MMCX-LP-066(40) includes 2 additional components per unit (1 connector and 1 heat shrink), while MMCX-LP-088(40) is supplied without accessories. All electrical and mechanical parameters are identical.

Q: Can I substitute MMCX-LP-FHSB(40) for MMCX-LP-088(40) in production?

A: Yes. MMCX-LP-FHSB(40) is a direct parametric equivalent with no differences in electrical performance, mechanical fit, or environmental ratings. Both parts are Active status and RoHS compliant.

Q: Are all three parts suitable for -55°C to 85°C operating environments?

A: Yes. All three parts are rated for the identical operating temperature range of -55°C to 85°C and support 500 mating cycles.

Q: Do all parts carry the same compliance certifications?

A: Yes. MMCX-LP-088(40), MMCX-LP-066(40), and MMCX-LP-FHSB(40) are all RoHS compliant with MSL 1 rating, ECCN EAR99, and HTSUS 8536.69.4010 classification.
