HM2P08PMS124GF Equivalent & Substitute Parts

Part Overview

The HM2P08PMS124GF 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 substitute parts necessary for ongoing system support and new designs requiring compatible interconnect solutions.

Substitute Part Grouping Explanation

Substitution for the HM2P08PMS124GF is based on the following critical parameters:

Pitch (0.079" / 2.00mm): All substitute parts maintain identical pitch for mechanical and electrical compatibility
Termination (Press-Fit): All substitutes use press-fit termination, ensuring compatible PCB assembly processes
Mounting Type (Through Hole): All alternatives are through-hole mounted connectors
Operating Temperature Range (-55°C ~ 125°C): All substitutes support the full temperature range
Contact Finish (Gold): All substitutes feature gold or gold-palladium contact finish

The primary difference between the main part and substitutes is position count. The HM2P08PMS124GF provides 175 positions (125 + 50 ground), while all listed substitutes provide 125 positions. This represents a functional reduction suitable for applications not requiring the full ground pin complement of the original design.

Engineering Selection Recommendations

HARTING har-bus® HM Series (17021251201, 17021252201, 17151251201, 17151252201)

These connectors are active products with ROHS3 compliance. The HARTING parts maintain 0.079" (2.00mm) pitch and press-fit termination. Current rating is 1 A, which is lower than the original part. These are suitable for applications where the reduced current capacity is acceptable and RoHS3 compliance is required.

TE Connectivity Z-PACK Series (3-100141-0, 5100141-1, 5100141-4, 5100785-1, 5100785-9, 5646731-1)

These connectors are active products with RoHS compliance (RoHS or ROHS3). The TE Connectivity parts maintain 0.079" (2.00mm) pitch, press-fit termination, and 1.5 A current rating, matching the original part's current capacity. Voltage rating is 500Vrms, which is lower than the original 750Vrms. These are suitable for applications requiring higher current capacity and RoHS compliance.

Frequently Asked Questions (FAQ)

Q: Can I use a 125-position substitute in place of the 175-position HM2P08PMS124GF?

A: Substitution is possible only if your application does not require the additional 50 ground positions. The 125-position alternatives provide the same pitch, termination method, and temperature range. System design must accommodate the reduced position count.

Q: What is the difference between HARTING and TE Connectivity substitutes?

A: HARTING parts (17021251201, 17021252201, 17151251201, 17151252201) are rated for 1 A current. TE Connectivity parts (3-100141-0, 5100141-1, 5100141-4, 5100785-1, 5100785-9, 5646731-1) are rated for 1.5 A current, matching the original part. TE Connectivity parts also provide 500Vrms voltage rating versus no specified voltage for most HARTING variants.

Q: Are all substitutes RoHS compliant?

A: Yes. HARTING parts are ROHS3 compliant. TE Connectivity parts are either RoHS or ROHS3 compliant. The original HM2P08PMS124GF is RoHS non-compliant.

Q: What packaging options are available?

A: HARTING substitutes are supplied in Tube packaging. TE Connectivity substitutes are supplied in either Tube or Bulk packaging depending on the specific part number.

Q: Do all substitutes support the same temperature range?

A: Yes. All substitute parts support the full -55°C to 125°C operating temperature range of the original part.

Q: What is the difference between connector styles B 25 and AB 25?

A: Connector style designations are provided in the input data. Style B 25 is used by most substitutes. Style AB 25 is used by 17151251201, 17151252201, and 5646731-1. Mechanical compatibility must be confirmed based on your specific application requirements.
