HM2P08PMA331GF Equivalent & Substitute Parts

Part Overview

The HM2P08PMA331GF is a 175-position backplane connector header manufactured by Amphenol ICC (FCI) with 0.079" (2.00mm) pitch and press-fit termination. This connector is classified as obsolete, making equivalent and substitute parts necessary for ongoing system support and new designs. The part features gold-plated contacts rated for 1.5A at 750Vrms across an operating temperature range of -55°C to 125°C.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the HM2P08PMA331GF is determined by the following critical parameters: connector type (header, male pins), pitch (0.079" / 2.00mm), mounting type (through hole), termination method (press-fit), operating temperature range (-55°C to 125°C), and moisture sensitivity level (MSL 1).

The substitute parts are grouped into two categories based on position count:

Category 1: Direct Equivalent (175 Positions) HM2P08PMA331GFLF maintains identical electrical and mechanical specifications to the original part, differing only in packaging (tray) and product status (active). This part is the primary direct substitute.

Category 2: Functional Alternatives (125 Positions) Parts 17151251201, 17151252201, and 3-100141-0 provide functional substitution for applications requiring 125-position headers with identical pitch, mounting, and termination. These parts accommodate designs where the full 175-position configuration is not required. All three maintain the 0.079" (2.00mm) pitch, through-hole mounting, and press-fit termination essential for mechanical and electrical compatibility.

Parameter Comparison

Engineering Selection Recommendations

HM2P08PMA331GFLF is the recommended primary substitute for direct replacement applications. This part maintains identical position count (175), electrical ratings (1.5A, 750Vrms), and mechanical specifications while offering active product status and RoHS compliance. The only difference is packaging format (tray versus unspecified original packaging).

17151251201 and 17151252201 (HARTING har-bus® HM series) are suitable for applications where 125-position configuration meets functional requirements. Both parts maintain the critical 0.079" (2.00mm) pitch and press-fit termination. Current rating is reduced to 1 A, and voltage rating is 150V (17151251201) or unspecified (17151252201). Both are ROHS3 compliant and active products.

3-100141-0 (TE Connectivity Z-PACK series) provides an alternative 125-position solution with 1.5A current rating and 500Vrms voltage rating, closer to original electrical specifications than HARTING alternatives. This part is RoHS compliant and active.

Selection between 125-position alternatives depends on application voltage and current requirements. For designs requiring full 175-position capacity, HM2P08PMA331GFLF is the only viable substitute.

Frequently Asked Questions (FAQ)

Q: Can HM2P08PMA331GFLF be used as a direct replacement for HM2P08PMA331GF? A: Yes. Both parts share identical position count (175), pitch (2.00mm), mounting type (through hole), termination (press-fit), and electrical ratings (1.5A, 750Vrms). The substitute is active and RoHS compliant, whereas the original is obsolete.

Q: What is the difference between the 175-position and 125-position substitutes? A: The 175-position HM2P08PMA331GFLF maintains the original connector footprint and pin count. The 125-position alternatives (17151251201, 17151252201, 3-100141-0) reduce position count and row configuration from 5+2 rows to 5 rows. These are suitable only for applications where 125 positions satisfy functional requirements.

Q: Are the HARTING 125-position parts (17151251201, 17151252201) electrically equivalent? A: Both HARTING parts maintain the 0.079" (2.00mm) pitch and press-fit termination. However, current rating is reduced to 1 A (versus 1.5A original), and voltage rating is 150V (17151251201) or unspecified (17151252201), compared to 750Vrms original. Verify application requirements before selection.

Q: What is the difference between 17151251201 and 17151252201? A: Both are HARTING har-bus® HM series 125-position headers with identical mechanical specifications. The primary difference is connector usage designation: 17151251201 is general-purpose, while 17151252201 is specified for backplane-to-daughtercard applications. Electrical specifications are equivalent.

Q: Does packaging format affect electrical or mechanical performance? A: No. Packaging (tray, tube, bulk) affects logistics and handling only. HM2P08PMA331GFLF (tray packaging) and the original HM2P08PMA331GF are electrically and mechanically identical.

Q: Are all substitute parts MSL 1 rated? A: Yes. All listed substitutes maintain MSL 1 (Unlimited) moisture sensitivity level, matching the original part specification.
