MMCX-LP-066(40) Equivalent & Substitute Parts

Part Overview

The MMCX-LP-066(40) is an MMCX Connector Plug with male pin configuration, designed for 50 Ohm RF applications. This right-angle solder-terminated connector operates at frequencies up to 6 GHz and is rated for -55°C to 85°C operating temperature range. The connector features a gold-plated brass body with PTFE dielectric material and snap-on fastening. Currently in active product status with 951 units in stock, this component is RoHS compliant and suitable for free-hanging inline mounting applications. Substitute parts are identified when inventory constraints or application-specific requirements necessitate alternative sourcing while maintaining electrical and mechanical compatibility.

Substitute Part Grouping Explanation

The MMCX-LP-066(40) and MMCX-LP-FHSB(40) are classified as parametric equivalents based on identical electrical and mechanical specifications. Substitution eligibility is determined by the following critical parameters:

Electrical Parameters: Both parts maintain 50 Ohm impedance, support frequencies up to 6 GHz, and feature identical contact termination (solder) and shield termination (crimp) methods.

Mechanical Parameters: Both connectors share MMCX style, male pin plug configuration, free-hanging inline right-angle mounting, and snap-on fastening type with single port.

Material Specifications: Identical brass body with gold finish, phosphor bronze center contact with gold plating, and PTFE dielectric material ensure mechanical and electrical compatibility.

Environmental Ratings: Both parts operate across -55°C to 85°C temperature range with 500 mating cycles and MSL 1 (unlimited moisture sensitivity level).

Compliance: Both parts are RoHS compliant and carry identical ECCN (EAR99) and HTSUS (8536.69.4010) classifications.

The primary distinction between these parts is packaging configuration: MMCX-LP-066(40) includes 2 pcs (1 connector, 1 heat shrink), while MMCX-LP-FHSB(40) does not specify included accessories.

Parameter Comparison

Engineering Selection Recommendations

Both MMCX-LP-066(40) and MMCX-LP-FHSB(40) are active products from Hirose Electric Co Ltd with identical electrical and mechanical specifications. Selection between these parts should be based on:

Inventory Availability: MMCX-LP-066(40) has 951 units in stock versus 811 units for MMCX-LP-FHSB(40). For high-volume applications, the higher inventory level of MMCX-LP-066(40) may provide supply chain advantages.

Packaging Requirements: MMCX-LP-066(40) includes heat shrink tubing as part of the package, while MMCX-LP-FHSB(40) does not specify included accessories. Applications requiring integrated heat shrink protection should specify MMCX-LP-066(40).

Compliance Status: Both parts maintain RoHS compliance and identical regulatory classifications (ECCN EAR99, HTSUS 8536.69.4010), ensuring interchangeability in regulated applications.

Either part is suitable for RF applications operating at frequencies up to 6 GHz with 50 Ohm impedance across the -55°C to 85°C temperature range.
