Engineering Selection Recommendations
First Priority: HM2P08PDP285N9LF
This Amphenol ICC part maintains identical electrical and mechanical specifications to the obsolete HM2P08PDP285N9 while offering active product status and RoHS compliance. It is the direct functional equivalent with 150-position configuration and represents the preferred substitution path for designs requiring no layout modifications.
Secondary Priority: TE Connectivity Z-PACK Series (5100141-1, 5100785-1)
These parts provide 125-position headers with 1.5 A current rating and 500Vrms voltage rating. They maintain press-fit termination, through-hole mounting, and 0.079" pitch. RoHS compliance and active product status support long-term availability. Selection between 5100141-1 and 5100785-1 depends on packaging requirements (Tube vs. alternative specifications).
Tertiary Priority: TE Connectivity Z-PACK Series (100141-1, 3-100141-0, 5100141-4)
These 125-position alternatives offer equivalent electrical performance with 1.5 A current rating and 500Vrms voltage rating. 3-100141-0 and 5100141-4 provide RoHS compliance. These parts are suitable for applications where position count reduction from 150 to 125 is acceptable.
HARTING har-bus® HM Series (17021252201, 17151252201)
These 125-position headers provide ROHS3 compliance and active product status. Current rating is specified at 1.0 A, which is lower than the original 1.5 A specification. Voltage rating is not specified. These parts are suitable only for applications where the 1.0 A current rating meets system requirements.
Frequently Asked Questions (FAQ)
Q: Can HM2P08PDP285N9LF be used as a direct replacement for HM2P08PDP285N9?
A: Yes. HM2P08PDP285N9LF maintains identical position count (150), pitch (0.079"), mounting type (through-hole), termination method (press-fit), current rating (1.5 A), voltage rating (750Vrms), and operating temperature range (-55°C ~ 125°C). The primary differences are active product status and RoHS compliance.
Q: Why do most substitutes have 125 positions instead of 150?
A: The original HM2P08PDP285N9 configuration of 150 positions (125 + 25 Ground) is specific to the Amphenol ICC Millipacs® series. Equivalent 125-position headers from TE Connectivity and HARTING provide the core signal distribution architecture with reduced ground pin count. Design review is required to confirm compatibility with the reduced ground distribution.
Q: What is the difference between 5100141-1 and 5100785-1?
A: Both are TE Connectivity Z-PACK 125-position headers with identical electrical specifications (1.5 A, 500Vrms, -55°C ~ 125°C). The primary difference is the base product number designation (5100141 vs. 5100785). Both are RoHS compliant and active products. Selection depends on internal part numbering and inventory management requirements.
Q: Are HARTING har-bus® HM parts fully compatible?
A: HARTING 17021252201 and 17151252201 meet the pitch (0.079"), mounting type (through-hole), termination (press-fit), and operating temperature (-55°C ~ 125°C) requirements. However, the current rating is specified at 1.0 A, which is lower than the original 1.5 A specification. Voltage rating is not specified. These parts are compatible only if system current requirements do not exceed 1.0 A per contact.
Q: What packaging options are available?
A: HM2P08PDP285N9LF is supplied in Tray packaging. TE Connectivity parts are available in Tube (100141-1, 5100141-1, 5100785-1) or Bulk (3-100141-0, 5100141-4) packaging. HARTING parts are supplied in Tube packaging. Packaging selection affects handling, storage, and assembly processes.
Q: Does RoHS compliance affect electrical performance?
A: RoHS compliance does not alter electrical specifications. HM2P08PDP285N9LF, 3-100141-0, 5100141-1, 5100141-4, 5100785-1, and HARTING parts (17021252201, 17151252201) are RoHS compliant and maintain the same current rating, voltage rating, and operating temperature range as their non-compliant counterparts. Compliance status reflects manufacturing process and material composition.
