HM2P70PME124GL Equivalent & Substitute Parts

Part Overview

The HM2P70PME124GL is a 154-position backplane connector header manufactured by Amphenol ICC (FCI) with 0.079" (2.00mm) pitch and press-fit termination. This connector is classified as obsolete, making equivalent and substitute parts necessary for ongoing system support and new designs. The part features 110 signal positions plus 44 ground positions across 5 + 2 rows, rated for 1.5A at 750Vrms operation across -55°C to 125°C.

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following critical parameters: connector type (Header, Male Pins), pitch (0.079" / 2.00mm), mounting type (Through Hole), termination method (Press-Fit), current rating (1.5A minimum), voltage rating (500Vrms minimum), and operating temperature range (-55°C ~ 125°C). Parts are grouped into two categories based on position count compatibility:

Category 1 - Full Position Match (154 positions): Parts maintaining identical 154-position configuration with 110 signal + 44 ground positions across 5 + 2 rows.

Category 2 - Reduced Position Configuration (110 positions): Parts with 110 signal positions only, suitable for applications where ground plane separation is handled differently or where the reduced ground pin count is acceptable.

Engineering Selection Recommendations

HM2P70PME124GLLF is the direct equivalent substitute for HM2P70PME124GL. Both parts share identical electrical and mechanical specifications with 154-position configuration. The primary difference is product status: HM2P70PME124GLLF is active and RoHS compliant, whereas the original part is obsolete and non-compliant. Packaging differs (tray versus unspecified), and contact finish thickness is specified as flash versus 1.00µm. This part is the preferred choice for direct replacement in existing designs.

CP2-HAB110-GA1-FJ maintains full 154-position compatibility with identical row configuration (5 + 2). Manufactured by 3M under the MetPak™ CP2 series, this part is active and RoHS compliant. The connector style designation differs (AB 22 versus B 22), and voltage rating is not specified. This part is suitable for applications where CompactPCI Hot Swap compatibility is required.

5352132-1 is a reduced-position alternative with 110 positions across 5 rows only, eliminating the dedicated ground row. Manufactured by TE Connectivity under the Z-PACK series, this part is active and RoHS compliant. Voltage rating is 500Vrms, which is lower than the original 750Vrms specification. This part is applicable only when system design accommodates the reduced ground pin count and lower voltage rating.

Frequently Asked Questions (FAQ)

Q: Can HM2P70PME124GLLF be used as a direct replacement for HM2P70PME124GL?

A: Yes. Both parts are electrically and mechanically identical with 154 positions, 0.079" pitch, 5 + 2 row configuration, 1.5A current rating, and -55°C to 125°C operating range. HM2P70PME124GLLF is the active production equivalent with RoHS compliance.

Q: What is the difference between the 154-position and 110-position substitutes?

A: The 154-position parts (HM2P70PME124GLLF and CP2-HAB110-GA1-FJ) include 44 dedicated ground positions across 2 additional rows. The 110-position part (5352132-1) contains signal positions only across 5 rows. Selection depends on whether the PCB design requires dedicated ground pins or uses alternative grounding methods.

Q: Is 5352132-1 compatible with designs requiring 750Vrms operation?

A: No. The 5352132-1 is rated for 500Vrms maximum, which is below the original 750Vrms specification. This part is suitable only for applications with 500Vrms or lower voltage requirements.

Q: What are the packaging differences among substitute parts?

A: HM2P70PME124GL packaging is unspecified. HM2P70PME124GLLF is supplied in trays. 5352132-1 is supplied in tubes. CP2-HAB110-GA1-FJ packaging is unspecified. Packaging selection should align with assembly process requirements and inventory management practices.

Q: Are all substitute parts RoHS compliant?

A: HM2P70PME124GLLF and CP2-HAB110-GA1-FJ are RoHS compliant. 5352132-1 is RoHS compliant. The original HM2P70PME124GL is non-compliant. For applications requiring RoHS compliance, any of the three substitutes are acceptable.

Q: Which substitute is recommended for new designs?

A: HM2P70PME124GLLF is recommended for new designs requiring full 154-position compatibility and direct electrical equivalence. CP2-HAB110-GA1-FJ is recommended when CompactPCI Hot Swap functionality is required. 5352132-1 is recommended only when 110-position configuration and 500Vrms rating are acceptable.
