HM2R65PA510FN9 Equivalent & Substitute Parts

Part Overview

The HM2R65PA510FN9 is a 150-position receptacle connector from Amphenol ICC (FCI) in the Millipacs® series, designed for backplane applications with 0.079" (2.00mm) pitch and press-fit termination. This part is classified as obsolete, making equivalent substitutes necessary for new designs and ongoing production support. The connector features gold-plated contacts rated for 1.5A at 500V across an operating temperature range of -55°C to 125°C.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the HM2R65PA510FN9 is determined by strict alignment of electrical and mechanical parameters: connector type (receptacle, female sockets), pitch (0.079" / 2.00mm), mounting configuration (board edge, through hole, right angle), termination method (press-fit), current rating (1.5A), voltage rating (minimum 500V), operating temperature range (-55°C to 125°C), and connector style (AB 25). Position count variations are acceptable where the core signal and ground pin architecture remains compatible.

The substitute parts are grouped into two categories:

Direct Equivalent (Same Manufacturer): HM2R65PA510FN9LF maintains identical electrical and mechanical specifications with improved compliance status (RoHS Compliant, Active product status).

Cross-Manufacturer Alternatives (TE Connectivity): 5646547-1 and 646547-1 provide functional equivalence with position count reduction (138 positions) while maintaining all critical electrical and mechanical parameters.

Parameter Comparison

Engineering Selection Recommendations

HM2R65PA510FN9LF is the primary substitute for new designs and production transitions. It is manufactured by the same supplier (Amphenol ICC), maintains identical electrical and mechanical specifications, carries Active product status, and meets RoHS compliance requirements. This part is the direct functional replacement with improved regulatory standing.

5646547-1 and 646547-1 (TE Connectivity) serve as cross-manufacturer alternatives where design flexibility permits position count reduction from 150 to 138 positions. Both maintain all critical electrical parameters (1.5A, 500Vrms minimum, -55°C to 125°C), press-fit termination, and 2.00mm pitch. The 5646547-1 offers RoHS compliance; 646547-1 does not. Selection between these TE Connectivity options depends on regulatory compliance requirements for the end application.

Frequently Asked Questions (FAQ)

Q: Can HM2R65PA510FN9LF be used as a direct replacement for HM2R65PA510FN9?

A: Yes. HM2R65PA510FN9LF is a direct equivalent with identical position count (150), pitch (2.00mm), mounting configuration, and electrical ratings. The primary differences are improved product status (Active vs. Obsolete) and RoHS compliance.

Q: What is the impact of using 138-position connectors (5646547-1 or 646547-1) instead of the 150-position original?

A: The 138-position alternatives reduce ground pins from 25 to 13 while maintaining 125 signal positions. This substitution is valid only if the application design accommodates the reduced ground pin count. The electrical and mechanical interface parameters remain compatible.

Q: Are there packaging differences between substitute parts?

A: Yes. HM2R65PA510FN9LF is supplied in Tray packaging, while 5646547-1 and 646547-1 are supplied in Tube packaging. Packaging selection may affect handling, storage, and assembly processes.

Q: Which substitute part should be selected for RoHS-compliant applications?

A: HM2R65PA510FN9LF and 5646547-1 are both RoHS Compliant. The original HM2R65PA510FN9 and 646547-1 are non-compliant.

Q: Do all substitute parts support the same voltage rating?

A: HM2R65PA510FN9LF supports 750Vrms, exceeding the original 500V rating. Both TE Connectivity alternatives (5646547-1 and 646547-1) are rated at 500Vrms, matching the original specification.
