HM2P71PNE124GF Equivalent & Substitute Parts

Part Overview

The HM2P71PNE124GF is a 133-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 substitute parts necessary for ongoing system maintenance and new design implementations. The part features a 5+2 row configuration with 95 signal positions and 38 ground positions, designed for through-hole mounting applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the HM2P71PNE124GF is constrained by the following critical parameters:

Position Configuration: The main part contains 133 total positions (95 signal + 38 ground) across 5+2 rows. Available substitutes reduce the signal position count to 95 positions across 5 rows, eliminating the dedicated ground row configuration. This represents a functional reduction in connector capacity.

Electrical Specifications: All substitute parts maintain 0.079" (2.00mm) pitch and through-hole press-fit termination. Current ratings range from 1.0 A to 1.5 A. Voltage ratings are either unspecified or not provided in substitute documentation.

Compliance Status: The original part is RoHS non-compliant. Substitute parts from HARTING (17130951201, 17130952201) are ROHS3 compliant, while the 3M substitute (CP2-HAB095-GE1-KR) is RoHS compliant. This compliance difference may impact system-level certifications.

Connector Style: The original part uses style B 19; substitutes use style AB 19, indicating a design variation in connector geometry.

Temperature Range: All parts maintain -55°C ~ 125°C operating temperature compatibility.

Parameter Comparison

Engineering Selection Recommendations

For Active Production Systems: The HARTING parts (17130951201 and 17130952201) are preferred substitutes due to active product status and ROHS3 compliance. Part 17130952201 includes explicit backplane-to-daughtercard connector usage designation, making it suitable for systems requiring this specific application profile.

For Legacy System Maintenance: The 3M CP2-HAB095-GE1-KR provides an alternative from an established supplier with RoHS compliance. This part is designated for CompactPCI Hot Swap applications and may be appropriate for systems with specific thermal or mechanical requirements.

Compliance Considerations: Systems requiring RoHS compliance must transition from the non-compliant HM2P71PNE124GF. All three substitute options provide compliant alternatives. Systems with existing RoHS non-compliant certifications may continue using the original part if supply permits.

Position Reduction Impact: All substitutes provide 95 positions versus the original 133 positions. PCB layout and connector footprint modifications are required. The elimination of the dedicated ground row necessitates alternative grounding strategies in circuit design.

Frequently Asked Questions (FAQ)

Q: Can the 95-position substitutes directly replace the 133-position HM2P71PNE124GF?

A: Direct mechanical replacement is not possible. The substitute parts have 38 fewer positions and different row configurations (5 rows versus 5+2 rows). PCB layout modifications and connector footprint changes are required. Signal routing and grounding schemes must be redesigned.

Q: What is the difference between HARTING parts 17130951201 and 17130952201?

A: Both parts are 95-position headers with identical electrical and mechanical specifications. Part 17130952201 includes explicit designation for backplane-to-daughtercard connector usage. Selection between these parts depends on application-specific requirements and supplier availability.

Q: Are the HARTING substitutes compatible with the original Amphenol ICC connector?

A: Compatibility is limited to the 0.079" (2.00mm) pitch and press-fit termination method. The connector style differs (AB 19 versus B 19), and the position count reduction requires circuit redesign. Physical and electrical compatibility cannot be assumed without detailed application analysis.

Q: What is the impact of the current rating reduction from 1.5 A to 1.0 A in HARTING substitutes?

A: The HARTING parts are rated for 1.0 A per contact, compared to 1.5 A for the original part. Applications requiring current levels between 1.0 A and 1.5 A per contact must be re-evaluated. Total system current capacity may be affected depending on signal distribution across connector positions.

Q: Does the RoHS compliance difference affect substitution decisions?

A: RoHS compliance status affects system-level certifications and regulatory requirements. Transitioning from a non-compliant part to compliant substitutes may require documentation updates and supply chain verification. Existing systems with non-compliant certifications may continue using original stock if available.

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

A: HARTING parts are supplied in Tube packaging. The 3M substitute is supplied in Bulk packaging. Packaging selection may affect inventory management, handling procedures, and cost per unit.
