HM2P07PDP251N9LLF Equivalent & Substitute Parts

Part Overview

The HM2P07PDP251N9LLF is a 154-position header connector manufactured by Amphenol ICC (FCI) within the Millipacs® series. This through-hole press-fit connector features a 2.00mm pitch and is designed for backplane applications requiring high-density interconnection. The connector comprises 110 signal positions and 44 dedicated ground positions across 5 rows plus 2 ground rows, with gold-plated contacts rated for 1.5A at 750Vrms. The product maintains active status with full RoHS compliance and unlimited moisture sensitivity rating. Substitute parts are identified when equivalent electrical and mechanical parameters align with application requirements, particularly when inventory constraints or packaging preferences necessitate alternative sourcing.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HM2P07PDP251N9LLF is determined by alignment of the following critical parameters:

Pitch (0.079" / 2.00mm) — The connector spacing must remain identical to ensure PCB footprint compatibility and mating interface consistency.

Mounting Type (Through Hole) and Termination (Press-Fit) — These parameters define the physical installation method and must match to maintain assembly process compatibility.

Connector Type (Header, Male Pins) and Connector Style (A 22) — The connector gender and style classification must be preserved for proper mating with corresponding receptacles.

Operating Temperature Range (-55°C ~ 125°C) — The thermal operating envelope must be maintained or exceeded to ensure reliability across specified application conditions.

Contact Finish (Gold) — The plating specification ensures electrical performance and corrosion resistance consistency.

Voltage and Current Ratings (750Vrms, 1.5A) — These electrical parameters establish the maximum safe operating conditions and must not be reduced in substitute parts.

The identified substitute part 17011102402 (HARTING har-bus® HM series) shares the core electrical and mechanical parameters with the main part, with the exception of position count (110 vs. 154) and current rating (1A vs. 1.5A). This substitute is applicable only in applications where the reduced position count and lower current capacity are acceptable design modifications.

Parameter Comparison

Engineering Selection Recommendations

Selection between the HM2P07PDP251N9LLF and substitute part 17011102402 must be based on application-specific requirements:

The main part HM2P07PDP251N9LLF is the primary selection for applications requiring the full 154-position configuration with 44 dedicated ground positions and 1.5A current capacity. This part maintains active product status with RoHS compliance and is available in tray packaging.

The substitute part 17011102402 is applicable only when design modifications permit reduction to 110 positions and 1A current capacity. This HARTING connector maintains identical pitch, mounting type, termination method, and operating temperature range. Both parts achieve RoHS compliance, though the substitute carries ROHS3 designation. The substitute is available in tube packaging, which may influence procurement and handling procedures.

Voltage rating specification is absent from the substitute part datasheet. Confirmation of voltage compatibility with the 750Vrms requirement of the original application is necessary before substitution.

Frequently Asked Questions (FAQ)

Q: Can the 17011102402 be used as a direct replacement for the HM2P07PDP251N9LLF?

A: No. The substitute part has a reduced position count (110 vs. 154) and lower current rating (1A vs. 1.5A). Direct replacement is only possible if the application design can accommodate these reductions without functional impact.

Q: What are the critical parameters that must match for substitution?

A: Pitch (2.00mm), connector type (Header, Male Pins), connector style (A 22), mounting type (Through Hole), termination method (Press-Fit), and operating temperature range (-55°C ~ 125°C) must remain consistent. Current and voltage ratings must not be reduced below application requirements.

Q: Does the different packaging (Tray vs. Tube) affect connector performance?

A: Packaging format does not affect electrical or mechanical performance. Packaging differences impact procurement, storage, and assembly handling procedures only.

Q: Are both parts RoHS compliant?

A: Yes. The main part carries RoHS Compliant status, while the substitute carries ROHS3 Compliant status. Both meet RoHS requirements.

Q: What is the significance of the contact finish difference (Gold Flash vs. Gold or Gold-Palladium)?

A: Both finishes provide electrical conductivity and corrosion resistance. The substitute's dual-finish option (Gold or Gold-Palladium) offers equivalent performance to the main part's gold flash finish for the specified application parameters.

Q: Is voltage rating information available for the substitute part?

A: The voltage rating for part 17011102402 is not specified in the provided data. Verification against the 750Vrms requirement of the original application is required before substitution.
