HM2P70PME129GF Equivalent & Substitute Parts

Part Overview

The HM2P70PME129GF is a 154-position backplane connector header manufactured by Amphenol ICC (FCI) as part of the Millipacs® series. This press-fit connector is designed for CompactPCI P2/P5 applications with 0.079" (2.00mm) pitch and through-hole mounting. The part is currently obsolete, making equivalent substitutes necessary for new designs and ongoing production support.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HM2P70PME129GF is determined by the following critical parameters:

• Connector Type & Style: Header, Male Pins with B 22 or AB 22 connector style
• Position Count & Configuration: 154 positions (110 + 44 Ground) or 110 positions (for reduced-pin applications)
• Pitch & Row Configuration: 0.079" (2.00mm) pitch with 5 + 2 or 5 row arrangement
• Mounting & Termination: Through-hole press-fit termination
• Electrical Ratings: Current rating of 1.5 A; voltage rating of 500Vrms or higher
• Operating Temperature Range: -55°C to 125°C
• Contact Finish: Gold plating

Substitutes are grouped into two categories: direct equivalents (same 154-position configuration) and functional alternatives (110-position variants for applications requiring reduced pin count).

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalents (154-Position, Full Compatibility)

HM2P70PME129GFLF is the primary substitute for HM2P70PME129GF. Both are Amphenol ICC Millipacs® connectors with identical electrical and mechanical specifications. The GFLF variant is active in production, RoHS compliant, and available in tray packaging. This part is suitable for direct replacement in new designs.

5352128-1 (TE Connectivity Z-PACK) provides an alternative 154-position header with equivalent electrical performance. This part is active, RoHS compliant, and includes an alignment strip feature. Voltage rating is 500Vrms compared to the original 750Vrms specification.

CP2-HAB110-GA1-FJ (3M MetPak™ CP2) is an active 154-position connector suitable for CompactPCI Hot Swap applications. This part is RoHS compliant with a thinner gold contact finish (10.0µin). Voltage rating is not specified in available documentation.

Functional Alternative (110-Position, Reduced Pin Count)

5352132-1 (TE Connectivity Z-PACK) is a 110-position header for applications requiring reduced pin count. This part maintains the same pitch, current rating, and operating temperature range. It is active, RoHS compliant, and available in tube packaging. Use this part only when the application does not require the full 154-position configuration.

Compliance Considerations

For new designs requiring RoHS compliance, select HM2P70PME129GFLF, 5352128-1, 5352132-1, or CP2-HAB110-GA1-FJ. The original HM2P70PME129GF and TE Connectivity 352128-1 are non-compliant with RoHS regulations.

Frequently Asked Questions (FAQ)

Q: Can HM2P70PME129GFLF be used as a direct replacement for HM2P70PME129GF?

A: Yes. Both connectors share identical electrical and mechanical specifications: 154 positions, 0.079" pitch, 1.5 A current rating, -55°C to 125°C operating range, and gold-plated contacts. The GFLF variant is the active production equivalent and is RoHS compliant.

Q: What is the difference between the Amphenol and TE Connectivity 154-position headers?

A: HM2P70PME129GFLF (Amphenol) and 5352128-1 (TE Connectivity) are functionally equivalent with identical position count, pitch, and current rating. The TE Connectivity part includes an alignment strip feature and is rated for 500Vrms versus the Amphenol's 750Vrms. Both are active and RoHS compliant.

Q: When should 5352132-1 be used instead of the 154-position alternatives?

A: 5352132-1 is a 110-position connector suitable only for applications that do not require the full 154-position configuration. It maintains the same pitch, current rating, and operating temperature. Use this part only when pin count reduction is acceptable for the application.

Q: Are there packaging differences between substitute parts?

A: Yes. HM2P70PME129GFLF is supplied in trays, 5352128-1 and 5352132-1 in tubes, and CP2-HAB110-GA1-FJ in bulk. Packaging does not affect electrical or mechanical compatibility; selection depends on procurement and assembly requirements.

Q: What is the voltage rating difference between substitutes?

A: The original HM2P70PME129GF is rated for 750Vrms. Most active substitutes (5352128-1, 5352132-1) are rated for 500Vrms. CP2-HAB110-GA1-FJ does not specify a voltage rating. For applications requiring 750Vrms, HM2P70PME129GFLF maintains the original specification.

Q: Are all substitutes RoHS compliant?

A: HM2P70PME129GFLF, 5352128-1, 5352132-1, and CP2-HAB110-GA1-FJ are RoHS compliant. The original HM2P70PME129GF and TE Connectivity 352128-1 are non-compliant. For new designs, use RoHS-compliant alternatives.
