HM2P70PKE124GF Equivalent & Substitute Parts

Part Overview

The HM2P70PKE124GF is a 154-position backplane connector header manufactured by Amphenol ICC (FCI) in the Millipacs® series. This through-hole press-fit connector features a 2.00mm pitch and supports 1.5A current at 750Vrms. The part is currently listed as obsolete, making identification of equivalent and substitute components necessary for ongoing system support and procurement planning.

Substitute Part Grouping Explanation

Substitution eligibility for the HM2P70PKE124GF is determined by the following critical parameters:

Connector Type & Style: Header, Male Pins configuration (B 22 style)
Position Count & Ground Configuration: 154 total positions (110 signal + 44 ground)
Pitch & Row Configuration: 0.079" (2.00mm) pitch with 5 + 2 row arrangement
Mounting & Termination: Through-hole press-fit termination
Electrical Ratings: Minimum 1.5A current capacity and 500Vrms or higher voltage rating
Temperature Range: -55°C ~ 125°C operating window
Contact Finish: Gold plating

Substitute parts must maintain compatibility across all these parameters. Variations in position count, pitch, row configuration, or electrical ratings indicate functional incompatibility.

Engineering Selection Recommendations

HM2P70PKE124GFLF (Amphenol ICC - FCI): This part is the direct equivalent to HM2P70PKE124GF with identical electrical and mechanical specifications. The primary difference is product status (active vs. obsolete) and RoHS compliance. This is the preferred direct replacement for the obsolete HM2P70PKE124GF.

CP2-HAB110-GA1-FJ (3M MetPak™ CP2): This part maintains the 154-position configuration, 2.00mm pitch, 5 + 2 row arrangement, and press-fit termination. It is RoHS compliant and active in production. The connector style differs (AB 22 vs. B 22), and voltage rating is not specified. This part is suitable for applications where the CompactPCI Hot Swap specification is acceptable.

5352132-1 (TE Connectivity Z-PACK): This part has a reduced position count (110 positions, 5 rows only) compared to the original 154-position configuration. The voltage rating is 500Vrms, which is lower than the original 750Vrms specification. This part is not a direct substitute due to position count and voltage rating differences.

Frequently Asked Questions (FAQ)

Q: Can HM2P70PKE124GFLF be used as a direct replacement for HM2P70PKE124GF?

A: Yes. HM2P70PKE124GFLF maintains identical electrical and mechanical specifications: 154 positions, 2.00mm pitch, 5 + 2 row configuration, 1.5A current rating, and 750Vrms voltage rating. The primary differences are product status (active) and RoHS compliance.

Q: Is 5352132-1 compatible with the original HM2P70PKE124GF?

A: No. The 5352132-1 has 110 positions with 5 rows only, compared to the original 154 positions with 5 + 2 rows. Additionally, the voltage rating is 500Vrms versus 750Vrms. These differences indicate functional incompatibility.

Q: What is the significance of the connector style designation (B 22 vs. AB 22)?

A: Connector style designations indicate physical and electrical configuration differences. While CP2-HAB110-GA1-FJ uses AB 22 style versus B 22 for the original part, both maintain the same pitch, row configuration, and press-fit termination. Style differences may affect mechanical fit and should be verified against PCB layout requirements.

Q: Does packaging type affect electrical performance?

A: No. Packaging differences (bulk, tray, tube) are logistics and handling considerations only. They do not affect connector electrical or mechanical performance.

Q: Why is RoHS compliance status important for this connector?

A: RoHS compliance status indicates regulatory conformance for lead-free manufacturing. HM2P70PKE124GFLF and CP2-HAB110-GA1-FJ are RoHS compliant, while the original HM2P70PKE124GF is not. Compliance requirements depend on end-use application and regional regulations.

Q: Can the 3M CP2-HAB110-GA1-FJ be used in non-CompactPCI applications?

A: The CP2-HAB110-GA1-FJ is specified for CompactPCI Hot Swap applications. While it maintains the same pitch, position count, and press-fit termination, use outside the specified application domain requires verification of mechanical fit and electrical compatibility with the target system.
