HM2P08PDE121N9LLF Equivalent & Substitute Parts

Part Overview

The HM2P08PDE121N9LLF is a 175-position backplane connector header manufactured by Amphenol ICC (FCI) in the Millipacs® series. This through-hole, press-fit connector features a 2.00mm pitch and supports 1.5A current at 750Vrms, operating across -55°C to 125°C. The connector is RoHS compliant and currently active in production. Substitute parts are identified for applications requiring reduced position counts or alternative manufacturer sourcing while maintaining core electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HM2P08PDE121N9LLF is determined by the following core parameters:

Pitch (0.079" / 2.00mm), Mounting Type (Through Hole), Termination (Press-Fit), Connector Type (Header, Male Pins), Operating Temperature Range (-55°C ~ 125°C), and Moisture Sensitivity Level (MSL 1).

The identified substitute parts maintain these critical parameters. However, the HM2P08PDE121N9LLF features 175 total positions (125 signal + 50 ground), while substitute parts are available in 125-position configurations. This position reduction represents a functional limitation in applications requiring the full 175-position capacity. Substitutes are suitable only for designs that can accommodate the reduced position count while maintaining the same pitch, mounting, and termination specifications.

Parameter Comparison

Engineering Selection Recommendations

All three connectors maintain active product status and comply with RoHS requirements, ensuring long-term availability and regulatory compliance. The HM2P08PDE121N9LLF remains the primary choice for applications requiring 175-position capacity with 750Vrms voltage rating and 1.5A current capability.

The 17151252201 (HARTING) substitute provides 125-position capacity with identical pitch and temperature range. This part is suitable for designs that do not require the additional 50 ground positions. Note that the current rating is reduced to 1 A, and voltage rating is not specified.

The 3-100141-0 (TE Connectivity) substitute also provides 125-position capacity and maintains the 1.5A current rating and -55°C to 125°C operating range. The voltage rating is specified at 500Vrms, which is lower than the main part. This substitute is appropriate for applications with reduced voltage requirements.

Selection between substitutes should be based on position count requirements, current and voltage specifications of the target application, and preferred manufacturer sourcing.

Frequently Asked Questions (FAQ)

Q: Can the 125-position substitutes directly replace the 175-position HM2P08PDE121N9LLF?

A: Direct replacement is not possible. The HM2P08PDE121N9LLF contains 175 positions (125 signal + 50 ground), while substitutes provide only 125 positions. Substitutes are suitable only for applications designed for 125-position connectors.

Q: What are the key compatibility criteria for these substitutes?

A: All three connectors share identical pitch (2.00mm), mounting type (through hole), termination method (press-fit), connector type (header, male pins), and operating temperature range (-55°C to 125°C). These parameters define mechanical and electrical compatibility within this product category.

Q: How do current and voltage ratings differ among these parts?

A: The main part (HM2P08PDE121N9LLF) supports 1.5A at 750Vrms. The HARTING substitute (17151252201) is rated for 1A with unspecified voltage. The TE Connectivity substitute (3-100141-0) supports 1.5A at 500Vrms. Applications must verify that substitute ratings meet or exceed design requirements.

Q: Are all parts RoHS compliant?

A: Yes. The HM2P08PDE121N9LLF and 3-100141-0 are RoHS Compliant. The 17151252201 is ROHS3 Compliant. All parts meet RoHS requirements and are suitable for regulated applications.

Q: What is the significance of MSL 1 rating?

A: MSL 1 (Unlimited) indicates these connectors have unlimited shelf life and do not require special moisture control during storage or handling. All three parts carry this rating.

Q: How do packaging formats differ?

A: The main part is supplied in Tray packaging. The HARTING substitute is supplied in Tube. The TE Connectivity substitute is supplied in Bulk. Packaging format does not affect electrical or mechanical compatibility but may influence logistics and handling procedures.
