HM2P71PME124GF Equivalent & Substitute Parts

Part Overview

The HM2P71PME124GF is a 133-position (95 + 38 ground) header connector with male pins, manufactured by Amphenol ICC (FCI) as part of the Millipacs® series. This backplane connector features 0.079" (2.00mm) pitch press-fit termination and is designed for CompactPCI P0/P3 applications. The part is currently obsolete, making identification of equivalent and substitute components essential for system maintenance, repair, and redesign efforts.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the HM2P71PME124GF is determined by the following critical parameters:

Group 1: Direct Equivalent (Same Position Count) Parts with 133 positions (95 + 38 ground), 0.079" (2.00mm) pitch, 5 + 2 row configuration, press-fit termination, and through-hole mounting. These parts maintain identical electrical and mechanical interfaces.

Group 2: Functional Equivalent (95-Position Configuration) Parts with 95 positions, 0.079" (2.00mm) pitch, 5 rows, press-fit termination, and through-hole mounting. These connectors provide the primary signal path (95 positions) but exclude the dedicated ground plane configuration (38 ground positions) of the original part.

Substitution eligibility is strictly limited to parts matching these configurations. Connector style, contact finish, operating temperature range, and termination method must align with the original specification.

Parameter Comparison

Engineering Selection Recommendations

Direct Replacement (133-Position Configuration):

HM2P71PME124GFLF is the primary direct equivalent, maintaining identical position count, pitch, row configuration, and electrical ratings. This part is currently active and RoHS compliant, addressing the obsolescence of the original HM2P71PME124GF.

5352127-1 (TE Connectivity Z-PACK series) provides an alternative 133-position solution with active product status and RoHS compliance. The voltage rating is specified at 500Vrms compared to the original 750Vrms specification.

Functional Replacement (95-Position Configuration):

17130951201 and 17130952201 (HARTING har-bus® HM series) are 95-position alternatives suitable for applications requiring only the primary signal path without dedicated ground plane configuration. Both parts are ROHS3 compliant and active. Current rating is specified at 1 A compared to the original 1.5 A.

CP2-HAB095-GE1-KR (3M MetPak™ CP2 series) is a 95-position alternative with active product status and RoHS compliance. This part is designated for CompactPCI Hot Swap applications.

Selection between 133-position and 95-position alternatives depends on system architecture requirements regarding ground plane configuration and signal integrity specifications.

Frequently Asked Questions (FAQ)

Q: Can the 95-position parts replace the 133-position original connector?

A: 95-position connectors provide the primary signal path but exclude the dedicated 38-ground position configuration. Substitution is valid only if the system design does not require the additional ground plane structure. Verify PCB layout and backplane design compatibility before selection.

Q: What is the significance of the contact finish thickness difference between 30.0µin and Flash?

A: Contact finish thickness affects durability and wear characteristics. The original specification of 30.0µin (0.76µm) provides a defined gold plating thickness. Flash finish indicates a minimal gold coating. Selection depends on connector mating cycle requirements and environmental exposure specifications.

Q: Are the HARTING 95-position parts suitable for CompactPCI P0/P3 applications?

A: HARTING parts 17130951201 and 17130952201 are specified for backplane-to-daughtercard and general backplane applications. Verify connector usage designation against specific CompactPCI standard requirements for your application.

Q: What compliance considerations apply when replacing the obsolete HM2P71PME124GF?

A: The original part is RoHS non-compliant. All active substitute parts listed are RoHS compliant (either RoHS or ROHS3). System-level compliance requirements must be evaluated when transitioning from non-compliant to compliant components.

Q: How do voltage rating differences affect part selection?

A: The original HM2P71PME124GF is rated at 750Vrms. The TE Connectivity 5352127-1 is rated at 500Vrms. HARTING and 3M parts do not specify voltage ratings. Verify system voltage requirements and select parts with equal or higher voltage ratings for the intended application.

Q: What packaging options are available for these substitute parts?

A: HM2P71PME124GFLF is supplied in Tray packaging. HARTING parts (17130951201, 17130952201) and TE Connectivity 5352127-1 are supplied in Tube packaging. 3M CP2-HAB095-GE1-KR is supplied in Bulk packaging. Packaging selection may affect procurement, handling, and storage requirements.
