HM2P66PME124GFLF Equivalent & Substitute Parts

Part Overview

The HM2P66PME124GFLF is a 146-position header connector manufactured by Amphenol ICC (FCI) within the Millipacs® series. This through-hole press-fit connector features a 2.00mm pitch and supports 1.5A current at 750Vrms, designed for backplane applications requiring high-density interconnection. The part maintains Active product status with full RoHS compliance and unlimited moisture sensitivity rating. Substitute parts are identified to address inventory availability, packaging preferences, or specific application requirements while maintaining core electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HM2P66PME124GFLF is determined by the following critical parameters:

Connector pitch (0.079" / 2.00mm) must remain constant to ensure PCB footprint compatibility. Mounting type (through-hole) and termination method (press-fit) are non-negotiable for assembly process alignment. Current rating (1.5A minimum) and operating temperature range (-55°C to 125°C) establish the electrical performance envelope. Position count and row configuration may vary if the application permits reduced connectivity or alternative layout configurations.

The identified substitute part 5352639-1 maintains pitch, mounting type, termination, current rating, and temperature range compatibility. The primary difference is position count (110 vs. 146) and row configuration (5 vs. 5+2), which represents a reduced-density variant suitable for applications not requiring the full 146-position capacity.

Parameter Comparison

Engineering Selection Recommendations

Both the HM2P66PME124GFLF and 5352639-1 maintain Active product status with full regulatory compliance. The HM2P66PME124GFLF provides higher position density (146 positions) and elevated voltage rating (750Vrms), making it suitable for applications requiring maximum interconnection capacity and higher voltage tolerance. The 5352639-1 offers reduced position count (110 positions) with lower voltage rating (500Vrms), appropriate for applications with lower connectivity demands and voltage requirements.

Selection between these parts depends on circuit design requirements. If the application requires all 146 positions and 750Vrms operation, the HM2P66PME124GFLF is the required choice. If the application can operate with 110 positions and 500Vrms maximum, the 5352639-1 provides an alternative with equivalent current handling and temperature performance.

Frequently Asked Questions (FAQ)

Q: Can 5352639-1 be used as a direct replacement for HM2P66PME124GFLF?

A: Direct replacement is not possible due to position count and voltage rating differences. The 5352639-1 provides 110 positions versus 146, and supports 500Vrms versus 750Vrms. Use 5352639-1 only if your application requires 110 or fewer positions and operates at 500Vrms or below.

Q: Are the pitch and mounting specifications identical?

A: Yes. Both connectors maintain 0.079" (2.00mm) pitch, through-hole mounting, and press-fit termination. PCB footprint compatibility for the 110-position section is maintained.

Q: What is the difference in packaging?

A: HM2P66PME124GFLF ships in Tray packaging, while 5352639-1 ships in Tube packaging. This affects handling and storage but does not impact electrical or mechanical performance.

Q: Do both parts meet current environmental standards?

A: Yes. HM2P66PME124GFLF is RoHS Compliant, and 5352639-1 is ROHS3 Compliant. Both maintain MSL 1 (Unlimited) rating and support the same operating temperature range (-55°C to 125°C).

Q: What is the primary limiting factor for substitution?

A: Position count and voltage rating are the primary limiting factors. The substitute part accommodates only 110 positions and 500Vrms maximum, compared to 146 positions and 750Vrms for the main part.
