HM2P71PMS2P4GF Equivalent & Substitute Parts

Part Overview

The HM2P71PMS2P4GF is a 133-position backplane connector header manufactured by Amphenol ICC (FCI) in the Millipacs® series. This through-hole press-fit connector features a 2.00mm pitch configuration with 95 signal positions and 38 ground positions across 5 rows plus 2 ground rows. The part is classified as obsolete, making identification of active equivalent alternatives essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the HM2P71PMS2P4GF is determined by the following critical parameters:

• Pitch (2.00mm): All substitutes maintain identical 0.079" (2.00mm) spacing for PCB compatibility
• Mounting Type (Through Hole): All alternatives use through-hole press-fit termination
• Connector Type (Header, Male Pins): All substitutes are male pin headers for backplane applications
• Operating Temperature Range (-55°C ~ 125°C): All alternatives support the full temperature specification
• Moisture Sensitivity Level (MSL 1): All substitutes maintain unlimited moisture tolerance

The substitute parts are grouped into two categories:

Category 1 - Direct Amphenol ICC Equivalent: HM2P71PMS2P4GFLF maintains identical 133-position configuration with active product status and RoHS compliance.

Category 2 - Cross-Manufacturer Alternatives: HARTING 17130951201, HARTING 17130952201, and 3M CP2-HAB095-GE1-KR provide 95-position header configurations. These alternatives reduce the total position count but maintain the core 2.00mm pitch, through-hole press-fit architecture, and temperature specifications required for backplane-to-daughtercard connectivity.

Parameter Comparison

Engineering Selection Recommendations

HM2P71PMS2P4GFLF is the primary substitute for the obsolete HM2P71PMS2P4GF. This Amphenol ICC part maintains identical electrical and mechanical specifications while offering active product status and RoHS compliance. The transition from bulk to tray packaging provides improved handling and inventory management.

HARTING 17130951201 and 17130952201 serve as cross-manufacturer alternatives for applications where 95-position configuration is acceptable. Both parts are ROHS3 compliant with active status. The 17130952201 variant specifies backplane-to-daughtercard connector usage, aligning with CompactPCI applications.

3M CP2-HAB095-GE1-KR provides a 95-position alternative within the MetPak™ CP2 series, specifically designed for CompactPCI hot-swap applications. This part maintains RoHS compliance and active product status.

Selection between the 133-position and 95-position alternatives depends on system architecture requirements. The 133-position configuration (HM2P71PMS2P4GFLF) preserves the original design intent with dedicated ground positions. The 95-position alternatives (HARTING and 3M) are suitable for systems where reduced position count aligns with board layout and signal routing requirements.

Frequently Asked Questions (FAQ)

Q: Can HM2P71PMS2P4GFLF directly replace HM2P71PMS2P4GF?

A: Yes. HM2P71PMS2P4GFLF is the direct equivalent, maintaining identical position count (133), pitch (2.00mm), row configuration (5 + 2), and electrical ratings. The primary difference is product status (active versus obsolete) and packaging format (tray versus bulk).

Q: What is the key difference between the 133-position and 95-position substitutes?

A: The original HM2P71PMS2P4GF and its direct equivalent HM2P71PMS2P4GFLF provide 133 total positions (95 signal + 38 ground) across 5 signal rows plus 2 dedicated ground rows. The HARTING and 3M alternatives provide 95 positions across 5 rows without dedicated ground row separation. Both configurations maintain 2.00mm pitch and through-hole press-fit termination.

Q: Are the HARTING and 3M parts compatible with existing PCB designs for the HM2P71PMS2P4GF?

A: Compatibility depends on PCB layout. The 95-position alternatives have different footprints due to reduced position count and row configuration. PCB redesign is required if the original design utilizes the full 133-position capacity or relies on the dedicated ground row structure.

Q: What compliance certifications apply to these substitutes?

A: HM2P71PMS2P4GFLF, HARTING 17130951201, HARTING 17130952201, and 3M CP2-HAB095-GE1-KR all maintain MSL 1 (unlimited moisture sensitivity), ECCN EAR99 classification, and HTSUS 8536.69.4040 tariff code. RoHS compliance is confirmed for all active alternatives. REACH status varies: HM2P71PMS2P4GFLF is REACH Affected; HARTING parts are REACH Unaffected.

Q: What is the current rating difference between the main part and substitutes?

A: HM2P71PMS2P4GF specifies 1.5 A current rating. HARTING 17130951201 and 17130952201 specify 1 A. 3M CP2-HAB095-GE1-KR does not specify current rating in the provided data. System current requirements must be evaluated against these specifications.

Q: Are packaging differences significant for component selection?

A: HM2P71PMS2P4GF uses bulk packaging, while HM2P71PMS2P4GFLF uses tray packaging. HARTING parts use tube packaging, and 3M uses bulk packaging. Packaging affects handling, storage, and automated assembly compatibility but does not impact electrical or mechanical performance.
