HM2P65PDM3P5N9LF Equivalent & Substitute Parts

Part Overview

The HM2P65PDM3P5N9LF is a 147-position backplane connector header manufactured by Amphenol ICC (FCI) in the Millipacs® series. This press-fit through-hole connector features 125 signal positions plus 22 dedicated ground positions arranged in a 5+1 row configuration with 2.00mm pitch. The connector is designed for backplane-to-daughtercard applications and is currently in active production status with 738 units in stock.

Equivalent and substitute parts are necessary when the original part becomes unavailable, when alternative packaging or compliance certifications are required, or when design flexibility permits selection from multiple qualified manufacturers meeting the same electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitute parts for the HM2P65PDM3P5N9LF are qualified based on the following critical parameters that determine functional interchangeability:

Position Count: 125 positions (signal only, excluding ground pins)
Pitch: 0.079" (2.00mm)
Row Configuration: 5 rows
Connector Style: AB 25 or B 25 configurations
Mounting Type: Through Hole
Termination Method: Press-Fit
Operating Temperature Range: -55°C ~ 125°C minimum
Contact Finish: Gold plating
Moisture Sensitivity Level: 1 (Unlimited)

The substitute parts listed below meet these core parameters. Variations in current rating, voltage rating, contact finish thickness, packaging format, and manufacturer-specific series designations do not preclude substitution when the application requirements fall within the specified ranges of the substitute part.

Engineering Selection Recommendations

TE Connectivity Z-PACK Series (5100141-4, 5100785-1, 5100785-9, 5646731-1): These parts maintain the full 1.5 A current rating and meet or exceed the voltage requirements of the original HM2P65PDM3P5N9LF. All are RoHS compliant and rated for the full -55°C to 125°C operating range. The Z-PACK series offers multiple packaging options (Bulk and Tube) and connector style variants (B 25 and AB 25), providing flexibility for procurement and assembly workflows.

HARTING har-bus® HM Series (17021252201, 17151252201): These parts are ROHS3 compliant and maintain the full operating temperature range. The current rating is reduced to 1.0 A, which is suitable for applications where the original 1.5 A specification exceeds actual circuit requirements. Both parts are available in Tube packaging and offer AB 25 or B 25 connector style options.

3M MetPak™ CP2 Series (CP2-HB125-E1-KR): This part is ROHS3 compliant and suitable for CompactPCI Hot Swap applications. The operating temperature range is -40°C to 85°C, which is narrower than the original part. Selection of this part is appropriate only when the application environment does not require the extended -55°C lower temperature limit.

Frequently Asked Questions (FAQ)

Q: Can I substitute a 125-position connector for the original 147-position HM2P65PDM3P5N9LF?

A: The substitute parts listed are 125-position connectors without dedicated ground pins. The original part includes 22 dedicated ground positions in addition to 125 signal positions. Substitution is valid only if the PCB layout and circuit design accommodate the 125-position configuration without the separate ground row. Mechanical fit and electrical routing must be verified against the specific application.

Q: What is the difference between the HARTING 17021252201 and 17151252201 parts?

A: Both parts are 125-position, 2.00mm pitch headers in the har-bus® HM series with identical electrical specifications. The primary difference is the connector style designation: 17021252201 is B 25 configuration, while 17151252201 is AB 25 configuration. Selection depends on the mating connector style required by the application.

Q: Are all substitute parts RoHS compliant?

A: All substitute parts listed are RoHS compliant. The original HM2P65PDM3P5N9LF is RoHS Compliant. HARTING and 3M parts carry ROHS3 certification. TE Connectivity parts carry either RoHS Compliant or ROHS3 Compliant status. All meet regulatory requirements for lead-free manufacturing.

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

A: Substitute parts are available in three packaging formats: Tube (HARTING 17021252201, 17021252201; TE Connectivity 5100785-1, 5100785-9, 5646731-1), Bulk (TE Connectivity 5100141-4; 3M CP2-HB125-E1-KR), and Tray (original HM2P65PDM3P5N9LF). Packaging selection affects handling, storage, and assembly processes but does not impact electrical or mechanical performance.

Q: Can I use the 3M CP2-HB125-E1-KR in applications requiring -55°C operation?

A: No. The 3M CP2-HB125-E1-KR is rated for -40°C to 85°C operating temperature. Applications requiring the full -55°C to 125°C range must use alternative substitute parts from TE Connectivity or HARTING, or the original Amphenol ICC part.

Q: How do current ratings affect substitution decisions?

A: The original HM2P65PDM3P5N9LF is rated for 1.5 A per contact. TE Connectivity substitute parts maintain this 1.5 A rating. HARTING parts are rated for 1.0 A. Substitution with lower current-rated parts is valid only when circuit design ensures actual current per contact does not exceed the substitute part's rating. Applications requiring the full 1.5 A capability must use TE Connectivity or the original Amphenol ICC part.
