HM2P07PDP231N9LLF Equivalent & Substitute Parts

Part Overview

The HM2P07PDP231N9LLF is a 154-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 is designed for high-density interconnect applications requiring robust electrical performance. The connector combines 110 signal positions with 44 dedicated ground positions across a 5+2 row configuration. As an active product with full RoHS compliance and unlimited moisture sensitivity rating, this connector serves critical backplane applications where reliable signal and power distribution is essential. Equivalent and substitute parts are identified based on matching electrical specifications, mechanical compatibility, and termination methods.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HM2P07PDP231N9LLF is determined by the following critical parameters:

Primary Matching Criteria:

• Pitch: 0.079" (2.00mm) — exact match required
• Mounting Type: Through Hole — exact match required
• Termination Method: Press-Fit — exact match required
• Connector Type: Header, Male Pins — exact match required
• Operating Temperature Range: -55°C ~ 125°C — minimum requirement
• Voltage Rating: 750Vrms or higher — minimum requirement
• Current Rating: 1.5 A or higher — minimum requirement
• Contact Finish: Gold or equivalent — minimum requirement

Secondary Compatibility Factors:

• Number of Positions: Substitutes may have different position counts if the application permits reduced signal/ground distribution
• Number of Rows: Configuration may vary based on PCB layout requirements
• RoHS and REACH Compliance: Active product status and regulatory alignment

The identified substitute part 17011102402 (HARTING har-bus® HM series) meets the core electrical and mechanical parameters but differs in position count (110 vs. 154) and row configuration (5 vs. 5+2), making it suitable only for applications where the reduced position density is acceptable.

Parameter Comparison

Engineering Selection Recommendations

Primary Part (HM2P07PDP231N9LLF): Use the original Amphenol ICC part for applications requiring the full 154-position configuration with dedicated ground distribution across 5+2 rows. This part maintains active product status with RoHS compliance and is suitable for high-density backplane designs where maximum signal and power integrity is required.

Substitute Part (17011102402): The HARTING har-bus® HM 17011102402 is suitable only for applications where a 110-position, 5-row configuration is acceptable. This substitute has a lower current rating (1 A vs. 1.5 A) and does not provide the dedicated ground row structure of the main part. Use this substitute only when PCB layout constraints or application requirements permit reduced position density and lower current distribution. Verify that the application does not require the 44 dedicated ground positions present in the main part.

Both parts maintain identical operating temperature ranges (-55°C ~ 125°C), press-fit termination, and 2.00mm pitch, ensuring mechanical and thermal compatibility within their respective position configurations.

Frequently Asked Questions (FAQ)

Q: Can the 17011102402 substitute directly replace the HM2P07PDP231N9LLF?

A: Direct replacement is not possible. The substitute has 110 positions in a 5-row configuration versus 154 positions (110 + 44 Ground) in a 5+2 row configuration. The main part includes dedicated ground rows; the substitute does not. Substitution is only valid if the application requires fewer signal and ground connections.

Q: What is the significance of the 44 dedicated ground positions in the main part?

A: The 44 dedicated ground positions distributed across the 5+2 row structure provide enhanced ground plane connectivity and improved signal integrity in high-speed or high-current backplane applications. The substitute's 5-row configuration lacks this dedicated ground distribution.

Q: Are there packaging differences between these parts?

A: Yes. The HM2P07PDP231N9LLF is supplied in Tray packaging, while the 17011102402 is supplied in Tube packaging. Packaging differences may affect handling, storage, and automated assembly processes.

Q: Does the lower current rating of the substitute affect compatibility?

A: The substitute's 1 A current rating is lower than the main part's 1.5 A rating. If the application requires current distribution exceeding 1 A per contact, the substitute is not suitable. Verify actual current requirements before substitution.

Q: Are both parts RoHS compliant?

A: Yes. The main part is RoHS Compliant, and the substitute is ROHS3 Compliant. Both meet current RoHS requirements. The main part is REACH Affected; the substitute is REACH Unaffected. Verify REACH compliance requirements for your specific application and region.

Q: What is the pitch specification, and why is it critical for substitution?

A: Both parts have a 0.079" (2.00mm) pitch, which is the center-to-center distance between adjacent contact positions. Pitch is a critical mechanical parameter; any deviation makes the connector incompatible with the PCB footprint. Both parts match on this specification.

Q: Can the contact finish difference (Gold vs. Gold-Palladium) affect performance?

A: Both gold and gold-palladium finishes provide equivalent electrical performance and corrosion resistance for this application. The difference is acceptable from an engineering standpoint.
