Substitute Part Grouping Explanation

Substitution logic for the HM2P07PDP251N9 is based on the following allowed parameters:

Primary Substitution Criteria:

Connector type: Header, Male Pins
Pitch: 0.079" (2.00mm)
Mounting type: Through Hole
Termination: Press-Fit
Connector style: A 22
Operating temperature range: -55°C to 125°C
Contact finish: Gold
Features: Board Guide

Position Configuration Consideration: The main part HM2P07PDP251N9 contains 154 total positions (110 signal + 44 ground) across 5 + 2 rows. Substitute parts in this reference are primarily 110-position headers across 5 rows, representing the signal-carrying portion of the connector family. These 110-position variants maintain electrical and mechanical compatibility for applications requiring the core signal routing architecture.

Compliance Variations: Substitute parts differ in RoHS compliance status and REACH classification. The direct equivalent HM2P07PDP251N9LF maintains the 154-position configuration with active product status and RoHS compliance.

Engineering Selection Recommendations

Direct Equivalent (Recommended for Obsolescence Replacement): HM2P07PDP251N9LF is the active production equivalent of the obsolete HM2P07PDP251N9. Both maintain 154-position configuration with identical electrical ratings and mechanical specifications. The LF variant is RoHS compliant and carries active product status, making it the primary choice for new designs and direct replacement in existing applications.

Alternative 110-Position Headers (Signal Routing Applications): TE Connectivity Z-PACK series headers (5100143-1, 5106164-1, 5106413-1, 5188398-9, 5188731-1) and TE Connectivity 1-5100143-9 provide 110-position configurations suitable for applications requiring signal routing without the full 154-position ground plane structure. These parts maintain 2.00mm pitch, through-hole press-fit termination, and 1.5A current rating. Voltage rating is 500Vrms, which is lower than the original 750Vrms specification.

HARTING Alternative: 17011102402 from the har-bus® HM series provides 110-position configuration at 2.00mm pitch with press-fit termination. Current rating is 1.0A, which is lower than the original 1.5A specification. This part is suitable for lower-current applications within the same mechanical envelope.

Compliance Considerations: All substitute parts listed carry active product status and RoHS3 compliance or RoHS compliance, ensuring regulatory alignment for current manufacturing environments. The original HM2P07PDP251N9 is RoHS non-compliant and obsolete; HM2P07PDP251N9LF addresses both concerns.

Frequently Asked Questions (FAQ)

Q: Can I use a 110-position header as a direct replacement for the 154-position HM2P07PDP251N9? A: 110-position headers are mechanically and electrically compatible at the connector interface level (2.00mm pitch, press-fit termination, A 22 style). However, they lack the 44 dedicated ground positions present in the 154-position configuration. Application compatibility depends on whether the PCB layout and circuit design require the full 154-position ground plane structure.

Q: What is the difference between HM2P07PDP251N9 and HM2P07PDP251N9LF? A: Both parts are 154-position headers with identical electrical and mechanical specifications. The primary differences are product status (obsolete vs. active) and RoHS compliance (non-compliant vs. compliant). HM2P07PDP251N9LF is the active production equivalent.

Q: Why do TE Connectivity Z-PACK substitutes have a lower voltage rating (500Vrms vs. 750Vrms)? A: The voltage rating difference reflects design specifications for each connector family. Applications operating below 500Vrms can use these substitutes without electrical limitation. Applications requiring 750Vrms operation must use the original Amphenol ICC part or HM2P07PDP251N9LF.

Q: Are there packaging differences among the substitute parts? A: Yes. HM2P07PDP251N9LF is supplied in Tray packaging. TE Connectivity and HARTING substitutes are supplied in Tube packaging. Packaging selection may affect handling, storage, and automated assembly processes.

Q: Which substitute part has the highest current rating? A: TE Connectivity Z-PACK series (5100143-1, 5106164-1, 5106413-1, 5188398-9, 5188731-1) and 1-5100143-9 all maintain 1.5A current rating, matching the original specification. HARTING 17011102402 is rated for 1.0A.

Q: Is the HARTING 17011102402 suitable for high-current applications? A: No. The HARTING part is rated for 1.0A maximum, which is lower than the original 1.5A specification. It is suitable only for applications with current requirements at or below 1.0A per contact.

Q: What does "Board Guide" feature mean? A: Board Guide is a mechanical feature that aids connector alignment during PCB assembly. All listed parts include this feature, ensuring consistent mating alignment.
