HM2P07PDF2E1N9LF Equivalent & Substitute Parts

Part Overview

The HM2P07PDF2E1N9LF is a 154-position backplane connector header manufactured by Amphenol ICC (FCI) in the Millipacs® series. This press-fit through-hole connector features 110 signal positions plus 44 ground positions arranged in a 5+2 row configuration with 2.00mm pitch. The connector is currently active and widely used in backplane applications requiring high-density interconnection with robust grounding architecture.

Substitute parts become necessary when the original part reaches end-of-life status, inventory constraints occur, or design requirements allow for alternative connector configurations that maintain electrical and mechanical compatibility within specified parameters.

Substitute Part Grouping Explanation

Substitution eligibility for the HM2P07PDF2E1N9LF is determined by the following critical parameters:

Position Configuration: The main part contains 154 total positions (110 signal + 44 ground). Substitute parts must maintain either the identical 154-position configuration or provide 110-position signal-only variants where ground distribution is handled through alternative means.

Pitch and Row Arrangement: All substitute parts must maintain 0.079" (2.00mm) pitch. Row configuration may vary between 5 rows (110-position variants) or 5+2 rows (154-position variants) depending on the specific substitute.

Connector Type and Mounting: All substitutes are header connectors with male pins using through-hole press-fit termination, ensuring mechanical compatibility with existing PCB designs.

Electrical Ratings: Current rating and voltage rating parameters define the electrical capacity. The main part supports 1.5A at 750Vrms. Substitute parts may have different voltage ratings (300V to 500Vrms) but maintain the 1.5A current capacity where specified.

Operating Temperature Range: All parts operate across -55°C to 125°C, ensuring thermal compatibility.

Contact Finish and Compliance: Gold contact finish is maintained across all substitutes. RoHS and REACH compliance status varies by manufacturer and must be verified for specific applications.

Engineering Selection Recommendations

Full Position Configuration (154-Position Requirement):

When the design requires the complete 154-position configuration with integrated ground distribution, the PCN21B-110PB-2PF-G (Hirose Electric) is the only substitute offering identical position count and row arrangement. However, this part carries Obsolete product status, limiting its suitability for new designs or long-term supply chain reliability. The HM2P07PDF2E1N9LF remains the preferred active alternative for this configuration.

Signal-Only Configuration (110-Position Requirement):

When designs can accommodate 110-position signal-only headers with separate ground handling, three active substitutes are available:

The 5106164-1 (TE Connectivity) provides the highest compatibility with the main part, matching the 1.5A current rating and offering additional Alignment Strip features. This part maintains REACH Unaffected status and ROHS3 compliance.

The 5100143-1 (TE Connectivity) offers equivalent electrical performance with 1.5A current rating and 500Vrms voltage rating. REACH status is Vendor Undefined, requiring clarification for specific applications.

The 17011102402 (HARTING) operates at reduced current capacity (1.0A versus 1.5A) and does not specify voltage rating. This part is suitable only for applications where the lower current rating is acceptable.

Compliance Considerations:

All active substitutes maintain RoHS3 compliance. The main part and PCN21B-110PB-2PF-G are RoHS Compliant. REACH status varies: 5106164-1 is REACH Unaffected, while 5100143-1 is Vendor Undefined and 17011102402 is REACH Unaffected.

Voltage Rating Constraints:

The main part supports 750Vrms. Substitute parts operate at lower voltage ratings (300V to 500Vrms). Selection must account for application voltage requirements.

Frequently Asked Questions (FAQ)

Q: Can the 110-position substitutes directly replace the 154-position main part?

A: No. The 110-position variants (17011102402, 5100143-1, 5106164-1) contain fewer total positions and different row configurations. They are suitable only for applications where the design can accommodate reduced position count and alternative ground distribution methods. The PCN21B-110PB-2PF-G maintains the 154-position configuration but carries Obsolete status.

Q: What is the significance of the 5+2 row configuration versus 5-row configuration?

A: The 5+2 row arrangement in 154-position parts dedicates two additional rows to ground distribution. The 5-row configuration in 110-position parts provides signal positions only. Substitution between these configurations requires design-level evaluation of grounding architecture.

Q: Does the reduced current rating of the 17011102402 (1.0A) affect compatibility?

A: Yes. The main part supports 1.5A per contact. The 17011102402 is rated for 1.0A. Substitution is valid only when application current requirements do not exceed 1.0A per contact.

Q: Why is the PCN21B-110PB-2PF-G marked Obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. While inventory may be available, this part is not recommended for new designs or applications requiring long-term supply chain support.

Q: Are all substitutes compatible with existing PCB footprints?

A: All parts maintain 0.079" (2.00mm) pitch and through-hole press-fit termination. However, the 154-position parts (main part and PCN21B-110PB-2PF-G) have different physical footprints than 110-position variants due to row configuration differences. PCB layout compatibility must be verified before substitution.

Q: What packaging formats are available?

A: The main part is supplied in Tray packaging. Substitutes are available in Tube (17011102402, 5100143-1, 5106164-1) or Bulk (PCN21B-110PB-2PF-G) packaging. Packaging format does not affect electrical or mechanical compatibility.

Q: How do voltage rating differences impact substitution decisions?

A: The main part supports 750Vrms. Substitutes operate at 300V to 500Vrms. Selection must ensure the substitute voltage rating meets or exceeds the application requirement. Lower-rated parts are not suitable for high-voltage applications.
