HM2P08PDF2M0N9 Equivalent & Substitute Parts
Part Overview
The HM2P08PDF2M0N9 is a 125-position header connector with male pins manufactured by Amphenol ICC (FCI) in the Millipacs® series. This backplane connector features 0.079" (2.00mm) pitch, through-hole press-fit termination, and is rated for 1.5 A at 750Vrms across an operating temperature range of -55°C to 125°C. The part is currently obsolete, making equivalent substitutes necessary for ongoing system support and new designs requiring compatible backplane-to-daughtercard connectivity.

Substitute Part Grouping Explanation
Substitution eligibility is determined by strict alignment with the following core parameters: 125 positions, 0.079" (2.00mm) pitch, 5 rows, through-hole press-fit termination, header male pins connector type, and operating temperature range of -55°C to 125°C. All identified substitutes meet these baseline mechanical and electrical requirements.
Substitutes are grouped into two categories based on connector style compatibility:
Category 1: B 25 Connector Style (Direct Mechanical Compatibility) Parts with B 25 style maintain identical physical and electrical interface characteristics to the original HM2P08PDF2M0N9.
Category 2: AB 25 Connector Style (Alternative Style) Parts with AB 25 style represent alternative connector configurations within the same functional class, suitable where design flexibility permits style variation.
Current rating and voltage rating variations among substitutes reflect different design specifications; selection depends on application requirements within the stated operating parameters.

Engineering Selection Recommendations
For RoHS3 Compliance Requirements: HARTING 17021251201, 17021252201, 17151251201, and 17151252201 are active production parts with ROHS3 compliance certification. TE Connectivity 5100141-4 also meets ROHS3 compliance. These options are suitable for applications requiring current regulatory compliance.
For Current Rating Equivalence (1.5 A): TE Connectivity parts 3-100141-0, 5100141-1, 5100141-4, 5100785-1, 5100785-9, and 5646731-1 maintain the original 1.5 A current rating. HARTING substitutes operate at 1 A, representing a reduced current capacity.
For Voltage Rating Consideration: The original HM2P08PDF2M0N9 is rated at 750Vrms. TE Connectivity Z-PACK series substitutes are rated at 500Vrms. HARTING 17151251201 is rated at 150V. Applications requiring the full 750Vrms specification should evaluate voltage derating requirements.
For B 25 Connector Style (Direct Interface Compatibility): TE Connectivity 3-100141-0, 5100141-1, 5100141-4, 5100785-1, and 5100785-9 maintain B 25 style compatibility with the original part. HARTING 17021251201 and 17021252201 also provide B 25 style.
For Active Production Status: All listed substitutes except the original HM2P08PDF2M0N9 are in active production, ensuring long-term availability and supply chain continuity.
Frequently Asked Questions (FAQ)
Q: Can HARTING har-bus® HM series parts directly replace the Amphenol ICC HM2P08PDF2M0N9? A: HARTING parts 17021251201 and 17021252201 share identical mechanical specifications (125 positions, 2.00mm pitch, 5 rows, B 25 style, through-hole press-fit). However, the current rating is reduced from 1.5 A to 1 A. Voltage rating information is not specified for these parts. Compatibility depends on application current requirements.
Q: What is the difference between B 25 and AB 25 connector styles? A: Both styles accommodate 125 positions at 2.00mm pitch in a 5-row configuration. The style designation reflects internal contact arrangement and keying differences. B 25 and AB 25 are not mechanically interchangeable; connector style selection must match the mating receptacle design.
Q: Why do TE Connectivity Z-PACK substitutes have a lower voltage rating (500Vrms vs. 750Vrms)? A: Voltage rating reflects the dielectric withstand specification of the connector design. The 500Vrms rating of Z-PACK parts is a design parameter distinct from the original 750Vrms specification. Applications requiring 750Vrms operation must confirm voltage derating is acceptable or select parts with equivalent voltage ratings.
Q: Are all substitute parts RoHS compliant? A: HARTING parts are ROHS3 compliant. TE Connectivity parts carry either RoHS Compliant or ROHS3 Compliant status. The original HM2P08PDF2M0N9 is RoHS non-compliant. Regulatory requirements determine which compliance level is necessary for your application.
Q: What packaging options are available for substitutes? A: HARTING substitutes are supplied in Tube packaging. TE Connectivity substitutes are available in Tube or Bulk packaging depending on part number. Packaging selection affects handling, storage, and ordering quantities.
Q: Can I use a 1 A rated substitute in an application designed for 1.5 A? A: Current rating represents the maximum continuous current the connector contacts are designed to carry. Using a 1 A rated part in a 1.5 A application exceeds the component specification. Application current requirements must not exceed the substitute part's current rating.
