HM2P07PKA251GF Equivalent & Substitute Parts

Part Overview

The HM2P07PKA251GF is a 154-position backplane connector header manufactured by Amphenol ICC (FCI) as part of the Millipacs® series. This press-fit connector features male pins with 2.00mm pitch and is designed for through-hole mounting applications. The part is currently listed as obsolete, making identification of suitable substitute components essential for ongoing system support and new design implementations. Equivalent parts must maintain the same electrical performance characteristics, mechanical compatibility, and connector geometry to ensure proper functionality in existing or redesigned applications.

Substitute Part Grouping Explanation

Substitution of the HM2P07PKA251GF is determined by strict adherence to the following critical parameters:

Primary Substitution Criteria:

  • Pitch: 0.079" (2.00mm) — must match exactly
  • Connector Type: Header, Male Pins — must match exactly
  • Mounting Type: Through Hole — must match exactly
  • Termination: Press-Fit — must match exactly
  • Operating Temperature Range: -55°C to 125°C — must match or exceed
  • Contact Finish: Gold — must match or be compatible
  • Connector Style: A 22 — must match exactly

Substitute Parts Identified:

  1. HM2P07PKA251GFLF (Amphenol ICC) — Direct equivalent with identical electrical and mechanical specifications. Differs only in packaging (Tray vs. unspecified) and product status (Active vs. Obsolete). This is the recommended direct replacement.

  2. 17011102402 (HARTING har-bus® HM series) — Functional equivalent with 110-position configuration. Maintains critical parameters: 2.00mm pitch, through-hole press-fit termination, -55°C to 125°C operating range, and gold contact finish. Position count reduction (110 vs. 154) requires application-level compatibility verification.

  3. 3-5100143-0 (TE Connectivity Z-PACK series) — Functional equivalent with 110-position configuration. Maintains critical parameters: 2.00mm pitch, through-hole press-fit termination, -55°C to 125°C operating range, and gold contact finish. Current rating (1.5 A) and voltage rating (500Vrms) are specified. Position count reduction (110 vs. 154) requires application-level compatibility verification.

Engineering Selection Recommendations

First Priority: HM2P07PKA251GFLF

This part is the direct equivalent of the HM2P07PKA251GF with identical electrical and mechanical specifications. It is manufactured by the same supplier (Amphenol ICC), maintains active product status, and carries RoHS compliance certification. The only differences are packaging format (Tray) and product lifecycle status. This part is the optimal choice for direct replacement in existing designs or new implementations requiring the full 154-position configuration.

Secondary Priority: 3-5100143-0 (TE Connectivity Z-PACK)

This part is suitable for applications where a 110-position configuration is acceptable. It maintains the critical electrical parameters: 1.5 A current rating, 500Vrms voltage rating, and -55°C to 125°C operating range. The part is active, RoHS compliant, and available in production quantities. The reduced position count (110 vs. 154) requires verification that the application does not depend on the additional 44 ground positions or the 7-row configuration.

Tertiary Priority: 17011102402 (HARTING har-bus® HM)

This part is suitable for applications where a 110-position configuration is acceptable. It maintains the critical mechanical parameters: 2.00mm pitch, through-hole press-fit termination, and -55°C to 125°C operating range. The part is active and ROHS3 compliant. Current rating is specified at 1 A (lower than the main part's 1.5 A), and voltage rating is not specified. The reduced position count and lower current rating require application-level compatibility verification.

Frequently Asked Questions (FAQ)

Q: Can HM2P07PKA251GFLF be used as a direct replacement for HM2P07PKA251GF?

A: Yes. HM2P07PKA251GFLF is electrically and mechanically identical to HM2P07PKA251GF. Both parts feature 154 positions, 2.00mm pitch, 1.5 A current rating, 750Vrms voltage rating, and -55°C to 125°C operating temperature range. The primary difference is product status (Active vs. Obsolete) and packaging format (Tray). This is the recommended direct replacement.

Q: Why do 17011102402 and 3-5100143-0 have only 110 positions instead of 154?

A: These parts are from different manufacturer series (HARTING har-bus® HM and TE Connectivity Z-PACK respectively) and are designed with a 5-row configuration instead of the 5+2 row configuration of the main part. The 110-position count reflects this architectural difference. These parts are suitable only if the application does not require the additional 44 ground positions or the extended row configuration.

Q: What are the key parameters that determine substitutability?

A: The critical parameters are: pitch (0.079" / 2.00mm), connector type (Header, Male Pins), mounting type (Through Hole), termination method (Press-Fit), operating temperature range (-55°C to 125°C), and contact finish (Gold). All substitute parts maintain these parameters. Position count, current rating, and voltage rating are application-dependent and must be verified for compatibility.

Q: Are all substitute parts RoHS compliant?

A: Yes. HM2P07PKA251GFLF is RoHS Compliant, 17011102402 is ROHS3 Compliant, and 3-5100143-0 is RoHS Compliant. All substitute parts meet current environmental compliance requirements.

Q: What is the difference between the packaging formats?

A: The main part HM2P07PKA251GF has unspecified packaging. HM2P07PKA251GFLF is supplied in Tray packaging. 17011102402 is supplied in Tube packaging. 3-5100143-0 is supplied in Tube packaging. Packaging format affects handling, storage, and ordering quantities but does not impact electrical or mechanical performance.

Q: Can I use 3-5100143-0 if my application requires 1.5 A current rating?

A: Yes. 3-5100143-0 is rated for 1.5 A, matching the main part specification. However, 17011102402 is rated for only 1 A and would not be suitable for applications requiring 1.5 A.

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

A: The main part HM2P07PKA251GF is rated for 750Vrms. HM2P07PKA251GFLF maintains this 750Vrms rating. 3-5100143-0 is rated for 500Vrms. 17011102402 does not specify a voltage rating. For applications requiring 750Vrms operation, only HM2P07PKA251GFLF provides equivalent voltage performance.
