Substitute Part Grouping Explanation
Substitution for the HM2H08P1LF shroud is determined by the following critical parameters:
- Number of Positions: 125 (exact match required)
- Pitch: 0.079" (2.00mm) (exact match required)
- Connector Type: Header, Male Pins (functional equivalent to shroud for male pins)
- Mounting Type: Through Hole (exact match required)
- Termination: Press-Fit (compatible with through-hole applications)
- Number of Rows: 5 (primary configuration)
- Connector Style: B 25 or AB 25 (mechanical compatibility)
Substitute parts are grouped into two categories based on connector style compatibility:
Category 1 - Style B 25 Headers: HARTING 17021251201, 17021252201; TE Connectivity 3-100141-0, 5100141-4, 5100785-1, 5100785-9; 3M CP2-HB125-E1-KR
Category 2 - Style AB 25 Headers: HARTING 17151251201, 17151252201; TE Connectivity 5646731-1
All substitute parts maintain the 125-position, 2.00mm pitch, through-hole configuration required for mechanical and electrical compatibility.

Engineering Selection Recommendations
All listed substitute parts are active products with current manufacturing support, addressing the obsolescence of the HM2H08P1LF. Selection should be based on the following criteria:
HARTING har-bus® HM Series (17021251201, 17021252201, 17151251201, 17151252201): These parts maintain ROHS3 compliance and offer press-fit termination compatible with through-hole PCB applications. Parts 17151251201 and 17151252201 feature AB 25 connector style with specified voltage rating of 150V. All HARTING substitutes support operating temperatures from -55°C to 125°C.
TE Connectivity Z-PACK Series (3-100141-0, 5100141-4, 5100785-1, 5100785-9, 5646731-1): These parts provide higher current ratings (1.5A) and voltage ratings (500Vrms), offering enhanced electrical performance. Parts 5100141-4, 5100785-1, and 5100785-9 feature gold contact finish with specified thickness. Part 5646731-1 uses AB 25 connector style. All TE Connectivity substitutes support -55°C to 125°C operating temperature range.
3M MetPak™ CP2 Series (CP2-HB125-E1-KR): This part provides ROHS3 compliance and gold contact finish. Operating temperature range is -40°C to 85°C, which is narrower than other substitutes. Suitable for CompactPCI Hot Swap applications.
For applications requiring the full -55°C to 125°C temperature range, HARTING or TE Connectivity options are preferred. For CompactPCI environments, the 3M solution is specified.
Frequently Asked Questions (FAQ)
Q: Can the HM2H08P1LF shroud be directly replaced with a header connector?
A: The HM2H08P1LF is a shroud component designed for male pins. Substitute header connectors (17021251201, 17021252201, 17151251201, 17151252201, 3-100141-0, 5100141-4, 5100785-1, 5100785-9, 5646731-1, CP2-HB125-E1-KR) are functionally equivalent male pin headers with identical 125-position, 2.00mm pitch configuration. Mechanical compatibility depends on the mating connector design and PCB layout.
Q: What is the difference between B 25 and AB 25 connector styles?
A: Both B 25 and AB 25 are hard metric connector style designations. The primary difference is mechanical keying and polarization features. Parts with B 25 style include 17021251201, 17021252201, 3-100141-0, 5100141-4, 5100785-1, 5100785-9, and CP2-HB125-E1-KR. Parts with AB 25 style include 17151251201, 17151252201, and 5646731-1. Selection depends on the mating connector specification.
Q: Are all substitute parts RoHS compliant?
A: All substitute parts listed are RoHS compliant. HARTING and 3M parts meet ROHS3 requirements. TE Connectivity parts meet either RoHS or ROHS3 standards. The original HM2H08P1LF is RoHS Compliant.
Q: What is the significance of the 5+2 row configuration in the original part?
A: The HM2H08P1LF features 5+2 row configuration, indicating 5 main rows plus 2 additional rows. Substitute header parts listed feature 5-row configuration. Verify that the mating connector and PCB layout accommodate the 5-row standard configuration before substitution.
Q: Which substitute offers the highest current and voltage ratings?
A: TE Connectivity Z-PACK series parts (3-100141-0, 5100141-4, 5100785-1, 5100785-9, 5646731-1) provide 1.5A current rating and 500Vrms voltage rating. HARTING parts provide 1A current rating with voltage ratings up to 150V (17151251201, 17151252201). The 3M part does not specify current or voltage ratings.
Q: What packaging options are available?
A: HARTING parts are supplied in Tube packaging. TE Connectivity parts are supplied in either Tube or Bulk packaging. The 3M part is supplied in Bulk packaging. Packaging selection affects inventory management and handling procedures.
Q: Are there temperature range limitations with any substitute?
A: The 3M CP2-HB125-E1-KR operates from -40°C to 85°C, which is narrower than the -55°C to 125°C range supported by HARTING and TE Connectivity substitutes. Applications requiring full -55°C to 125°C operation should use HARTING or TE Connectivity options.
