MMCX-P-FHSB Equivalent & Substitute Parts

Part Overview

The MMCX-P-FHSB is a coaxial connector plug manufactured by Hirose Electric Co Ltd, designed for 50 Ohm RF applications with solder termination. This connector features a male pin configuration in a free-hanging (in-line) mounting style, suitable for frequencies up to 6 GHz. The part is currently listed as obsolete, making identification of equivalent and substitute parts essential for ongoing system support and component procurement.

Substitute Part Grouping Explanation

Substitution for the MMCX-P-FHSB is determined by strict equivalence across the following critical parameters: connector style (MMCX), connector type (plug, male pin), impedance (50 Ohms), contact termination (solder), shield termination (crimp), mounting type (free hanging in-line), fastening type (snap-on), frequency capability (6 GHz maximum), and operating temperature range (-55°C to 85°C).

Hirose Electric Co Ltd manufactures three parametric equivalents: MMCX-P-066(40), MMCX-P-088(40), and MMCX-P-FHSB(40). These parts share identical electrical and mechanical specifications with the main part but differ in product status and RoHS compliance. All three are available in bulk packaging and maintain active product status.

Amphenol RF manufactures one manufacturer-recommended substitute: 908-NM41300. This part meets all core functional requirements but introduces variations in material composition, operating temperature range, and compliance certifications.

Engineering Selection Recommendations

For applications requiring direct replacement of the obsolete MMCX-P-FHSB, the Hirose Electric Co Ltd parametric equivalents MMCX-P-066(40), MMCX-P-088(40), and MMCX-P-FHSB(40) provide identical electrical and mechanical performance with the advantage of active product status and RoHS compliance. These parts are available in bulk packaging and maintain full compatibility with the original design specifications.

The Amphenol RF 908-NM41300 serves as a manufacturer-recommended alternative for applications where extended operating temperature range (-65°C to 165°C) is required. This part maintains all core RF and mechanical parameters but introduces material and finish variations. Selection of this part should be based on specific thermal requirements that exceed the original specification range.

For new designs or systems with regulatory compliance requirements, selection of an active, RoHS-compliant part is recommended. The Hirose parametric equivalents are preferred for direct legacy system support due to identical specifications and established supply availability.

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-FHSB?

A: Yes. These three parts are parametric equivalents with identical electrical and mechanical specifications. The primary differences are product status (active versus obsolete) and RoHS compliance. All three maintain the same 50 Ohm impedance, solder termination, snap-on fastening, and 6 GHz frequency capability.

Q: What is the difference between the Hirose equivalents and the Amphenol RF 908-NM41300?

A: The Amphenol RF part meets all core MMCX connector specifications but differs in operating temperature range (-65°C to 165°C versus -55°C to 85°C), material composition (beryllium copper versus phosphor bronze), and body finish (white bronze versus gold). Selection depends on whether extended thermal performance is required.

Q: Are there packaging differences between these parts?

A: The Hirose parametric equivalents are available in bulk packaging. The original MMCX-P-FHSB and Amphenol RF 908-NM41300 do not specify packaging format in the provided data. Bulk packaging typically indicates standard reel or tape configurations suitable for automated assembly.

Q: Which part should be selected for new designs?

A: For new designs, any of the active Hirose parametric equivalents (MMCX-P-066(40), MMCX-P-088(40), or MMCX-P-FHSB(40)) are recommended due to RoHS compliance and established supply chains. The Amphenol RF 908-NM41300 is suitable if extended operating temperature capability is a design requirement.

Q: Does the Amphenol RF part require different PCB layout or assembly procedures?

A: The provided data confirms identical connector style, mounting type, and fastening mechanism. However, material and finish differences may affect soldering characteristics. Assembly procedure validation is recommended when transitioning between manufacturers.
