HM2P65PD5111N9 Equivalent & Substitute Parts

Part Overview

The HM2P65PD5111N9 is a 169-position (125 + 44 Ground) header connector manufactured by Amphenol ICC (FCI) from the Millipacs® series. This backplane connector features male pins with 0.079" (2.00mm) pitch, press-fit termination, and through-hole mounting. The part is currently obsolete, making identification of equivalent and substitute components essential for ongoing system support and new design implementations.

Substitute Part Grouping Explanation

Substitution eligibility for the HM2P65PD5111N9 is determined by the following critical parameters:

Primary Matching Criteria:

Pitch: 0.079" (2.00mm)
Mounting Type: Through Hole
Termination: Press-Fit
Connector Type: Header, Male Pins
Operating Temperature Range: -55°C ~ 125°C

Position Configuration Considerations: The main part contains 169 total positions (125 signal + 44 ground). Substitute parts may differ in total position count while maintaining the same pitch and electrical characteristics. The 125-position variants listed represent functional alternatives where the ground plane configuration differs from the original design.

Electrical Compatibility: Current rating and voltage rating must meet or exceed the application requirements. The main part specifies 1.5 A at 500V; substitutes with equal or higher ratings are electrically compatible.

Engineering Selection Recommendations

Direct Equivalent (Preferred for Existing Designs): HM2P65PD5111N9LF is the direct successor to the obsolete HM2P65PD5111N9. Both parts maintain identical position count (169), row configuration (5 + 2), and pitch (2.00mm). The LF variant is currently in active production status with improved RoHS compliance and higher voltage rating (750Vrms vs. 500V). This part is the primary recommendation for direct replacement in existing applications.

Functional Alternatives (Position Reduction): The HARTING 17151251201, HARTING 17151252201, and TE Connectivity 3-100141-0 are 125-position alternatives that maintain the same 2.00mm pitch and through-hole press-fit termination. These parts are suitable for applications where the reduced position count and simplified ground plane configuration are acceptable. All three alternatives are in active production with current RoHS compliance certifications.

Compliance Considerations: The original HM2P65PD5111N9 is RoHS non-compliant. All substitute parts listed are RoHS compliant, meeting current regulatory requirements for new designs and manufacturing environments.

Frequently Asked Questions (FAQ)

Q: Can HM2P65PD5111N9LF be used as a direct replacement for HM2P65PD5111N9? A: Yes. Both parts share identical electrical and mechanical specifications: 169 positions, 2.00mm pitch, 5 + 2 row configuration, press-fit termination, and -55°C to 125°C operating range. The LF variant is the active production equivalent.

Q: What is the difference between the 169-position and 125-position alternatives? A: The main part contains 169 total positions (125 signal + 44 ground). The 125-position alternatives contain only signal positions with a different ground plane architecture. Position count reduction may require PCB layout modifications.

Q: Are the HARTING and TE Connectivity parts electrically compatible? A: All listed substitutes maintain the same 2.00mm pitch, through-hole mounting, and press-fit termination. However, the HARTING parts specify 1 A current rating versus 1.5 A for the original and TE Connectivity part. Voltage ratings also differ: HARTING 17151251201 specifies 150V, while the original specifies 500V. Application current and voltage requirements must be verified.

Q: What packaging options are available? A: HM2P65PD5111N9LF is supplied in Tray packaging. HARTING parts (17151251201 and 17151252201) are supplied in Tube packaging. TE Connectivity 3-100141-0 is supplied in Bulk packaging. Packaging selection depends on assembly process requirements and inventory management.

Q: Are all substitute parts RoHS compliant? A: Yes. HM2P65PD5111N9LF is RoHS Compliant. HARTING parts are ROHS3 Compliant. TE Connectivity 3-100141-0 is RoHS Compliant. The original HM2P65PD5111N9 is RoHS non-compliant.

Q: Which substitute part has the highest voltage rating? A: HM2P65PD5111N9LF specifies 750Vrms, the highest among all listed parts. This exceeds the original part's 500V rating.
