HM2P40PD5111N9 Equivalent & Substitute Parts

Part Overview

The HM2P40PD5111N9 is a 154-position backplane connector header manufactured by Amphenol ICC (FCI) from the Millipacs® series. This press-fit through-hole connector features a 2.00mm pitch and supports 1.5A current at 750Vrms. The part is currently listed as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and new design implementations.

Substitute Part Grouping Explanation

Substitution eligibility for the HM2P40PD5111N9 is determined by the following critical parameters: connector type (Header, Male Pins), pitch (2.00mm), mounting method (Through Hole), termination technology (Press-Fit), operating temperature range (-55°C ~ 125°C), and contact finish (Gold). Position count and row configuration are secondary considerations when the primary electrical and mechanical interfaces remain compatible.

The substitute parts are grouped into two categories:

Direct Amphenol ICC Variant: HM2P40PD5111N9LF maintains identical specifications with active product status and improved packaging (Tray format).

Cross-Manufacturer Alternatives: Parts from HARTING (17011102402) and TE Connectivity (3-5100143-0) provide functional equivalence with reduced position counts (110 positions) but maintain core electrical ratings, pitch, termination method, and temperature range.

Engineering Selection Recommendations

HM2P40PD5111N9LF is the primary substitute for direct replacement. This part maintains identical electrical and mechanical specifications while offering active product status and RoHS compliance. The transition from unspecified packaging to Tray format provides improved handling and storage characteristics.

3-5100143-0 (TE Connectivity) is suitable for applications where 110-position capacity is sufficient. This part matches the original current rating (1.5A) and operating temperature range. The voltage rating of 500Vrms is lower than the original 750Vrms specification and must be evaluated against system requirements.

17011102402 (HARTING) provides an alternative with 110-position capacity and ROHS3 compliance. The current rating of 1A is reduced compared to the original 1.5A specification and requires assessment for the intended application.

Frequently Asked Questions (FAQ)

Q: Can HM2P40PD5111N9LF be used as a direct replacement for HM2P40PD5111N9?

A: Yes. Both parts share identical connector type, position count, pitch, row configuration, mounting method, termination technology, current rating, voltage rating, and operating temperature range. The primary difference is product status (Active vs. Obsolete) and packaging format (Tray vs. unspecified).

Q: What are the limitations when using 110-position alternatives?

A: The HARTING 17011102402 and TE Connectivity 3-5100143-0 provide 110 positions instead of 154. Applications requiring the full 154-position capacity, including 44 dedicated ground positions, cannot use these alternatives without circuit redesign. Additionally, the HARTING part has a reduced current rating (1A vs. 1.5A), and the TE Connectivity part has a reduced voltage rating (500Vrms vs. 750Vrms).

Q: Are all substitute parts RoHS compliant?

A: HM2P40PD5111N9LF is RoHS Compliant. 17011102402 is ROHS3 Compliant. 3-5100143-0 is RoHS Compliant. The original HM2P40PD5111N9 does not specify RoHS status.

Q: What is the difference between the packaging formats?

A: HM2P40PD5111N9LF is supplied in Tray packaging. 17011102402 and 3-5100143-0 are supplied in Tube packaging. Packaging selection affects handling, storage, and automated assembly compatibility.

Q: Can the contact finish Gold-Palladium used in 17011102402 be substituted for pure Gold?

A: The HARTING 17011102402 offers both Gold and Gold-Palladium contact finish options. Gold-Palladium provides enhanced wear resistance and is functionally compatible with Gold-finished mating connectors in standard applications.
