HM2P40PKA3R1GF Equivalent & Substitute Parts

Part Overview

The HM2P40PKA3R1GF is a 154-position backplane connector header manufactured by Amphenol ICC (FCI) from the Millipacs® series. This press-fit header features male pins with 0.079" (2.00mm) pitch and is designed for through-hole mounting applications. The part is currently classified as obsolete, making identification of equivalent and substitute components essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the HM2P40PKA3R1GF is determined by the following critical parameters: connector type (header, male pins), pitch (0.079" / 2.00mm), mounting method (through-hole press-fit), operating temperature range (-55°C ~ 125°C), and contact finish (gold). The substitute parts are grouped into two categories:

Category 1: Direct Equivalent (Same Position Count) The HM2P40PKA3R1GFLF maintains identical electrical and mechanical specifications to the original part, including the full 154-position configuration with 110 signal positions and 44 ground positions. The only difference is packaging format (tray versus bulk) and active product status.

Category 2: Functional Alternatives (Reduced Position Count) The HARTING 17011102402 and TE Connectivity 3-5100143-0 provide 110-position configurations with identical pitch, mounting type, and termination method. These parts accommodate applications requiring the signal and ground distribution available in the reduced position count while maintaining full electrical and mechanical compatibility within their specified parameters.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Same Footprint and Position Count): The HM2P40PKA3R1GFLF is the primary equivalent for the obsolete HM2P40PKA3R1GF. Both parts share identical electrical and mechanical specifications, including the 154-position configuration, 0.079" pitch, and press-fit termination. The HM2P40PKA3R1GFLF carries active product status and RoHS compliance, making it suitable for new designs and legacy system support. Packaging differs (tray versus bulk), but electrical performance is equivalent.

For Reduced Position Count Applications: The TE Connectivity 3-5100143-0 provides the closest match among 110-position alternatives, maintaining the 1.5 A current rating and 500Vrms voltage specification. This part is RoHS compliant and carries active product status. The HARTING 17011102402 offers an alternative 110-position solution with ROHS3 compliance and board guide features, though it specifies 1 A current rating and does not list voltage rating.

Compliance Considerations: All active substitute parts meet MSL 1 (Unlimited) moisture sensitivity requirements. The HM2P40PKA3R1GFLF and TE Connectivity 3-5100143-0 are RoHS compliant. The HARTING 17011102402 is ROHS3 compliant. Selection should account for specific regulatory requirements of the target application.

Frequently Asked Questions (FAQ)

Q: Can the HM2P40PKA3R1GFLF be used as a direct replacement for the HM2P40PKA3R1GF? A: Yes. Both parts are electrically and mechanically identical, with 154 positions, 0.079" pitch, press-fit termination, and identical current and voltage ratings. The primary difference is packaging format and product status (active versus obsolete).

Q: What is the difference between the 154-position and 110-position alternatives? A: The original HM2P40PKA3R1GF and its direct equivalent HM2P40PKA3R1GFLF provide 154 total positions (110 signal + 44 ground) across 5 + 2 rows. The 110-position alternatives (HARTING 17011102402 and TE Connectivity 3-5100143-0) provide 110 positions across 5 rows. These reduced-position parts are suitable only for applications that do not require the full 154-position configuration.

Q: Are there voltage or current rating differences between substitutes? A: The HM2P40PKA3R1GF and HM2P40PKA3R1GFLF both specify 1.5 A at 750Vrms. The TE Connectivity 3-5100143-0 specifies 1.5 A at 500Vrms. The HARTING 17011102402 specifies 1 A with no voltage rating listed. Applications requiring the full 750Vrms or 1.5 A rating should use the Amphenol or TE Connectivity parts.

Q: What is the packaging difference between HM2P40PKA3R1GF and HM2P40PKA3R1GFLF? A: The HM2P40PKA3R1GF is supplied in bulk packaging, while the HM2P40PKA3R1GFLF is supplied in tray packaging. Electrical and mechanical specifications are identical.

Q: Are all substitute parts RoHS compliant? A: The HM2P40PKA3R1GFLF and TE Connectivity 3-5100143-0 are RoHS compliant. The HARTING 17011102402 is ROHS3 compliant. All parts meet MSL 1 (Unlimited) moisture sensitivity requirements.

Q: Which substitute should be selected for new designs? A: For applications requiring the full 154-position configuration, use HM2P40PKA3R1GFLF. For applications compatible with 110 positions, the TE Connectivity 3-5100143-0 is recommended due to matching current rating (1.5 A) and voltage specification (500Vrms). The HARTING 17011102402 is suitable where the reduced current rating (1 A) and unspecified voltage rating are acceptable.
