HM2P07PKE128GF Equivalent & Substitute Parts

Part Overview

The HM2P07PKE128GF is a 154-position backplane connector header manufactured by Amphenol ICC (FCI) in the Millipacs® series. This press-fit connector features male pins with 2.00mm pitch and is designed for through-hole mounting applications. The part is currently listed as obsolete, making equivalent and substitute parts necessary for ongoing system support and new designs requiring compatible interconnect solutions.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the HM2P07PKE128GF is determined by the following critical parameters:

Primary Matching Criteria:

• Pitch: 0.079" (2.00mm)
• Connector Type: Header, Male Pins
• Mounting Type: Through Hole
• Termination: Press-Fit
• Operating Temperature Range: -55°C ~ 125°C
• Contact Finish: Gold

Position Configuration Considerations: The main part features 154 total positions (110 signal + 44 ground) arranged in 5 + 2 rows. Substitute parts are grouped into two categories:

1. Full 154-Position Equivalents - Direct replacements maintaining identical position count and row configuration
2. 110-Position Alternatives - Reduced position count variants that maintain signal integrity for applications not requiring the full ground plane configuration

Compliance and Status: Product status (active vs. obsolete) and RoHS compliance certifications are secondary selection factors based on application requirements and regulatory mandates.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (154-Position Configuration):

HM2P07PKE128GFLF is the primary equivalent, offering identical electrical and mechanical specifications to the original HM2P07PKE128GF while maintaining active product status and RoHS compliance. This part is preferred for new designs and ongoing production requiring the full 154-position configuration.

PCN21B-110PB-2PF-G provides a 154-position alternative from Hirose Electric with RoHS compliance, though it carries obsolete product status and operates at reduced voltage rating (300V vs. 750Vrms).

For 110-Position Configuration:

TE Connectivity parts 1-5100143-9 and 3-5100143-0 are active alternatives with 110-position headers, suitable for applications not requiring the full ground plane. Both maintain 1.5A current rating and 500Vrms voltage rating with active product status and RoHS compliance.

HARTING 17011102402 offers a 110-position alternative with active status and ROHS3 compliance, though current rating is reduced to 1.0A and voltage rating is not specified.

Compliance Considerations:

For applications requiring RoHS compliance, HM2P07PKE128GFLF, PCN21B-110PB-2PF-G, 1-5100143-9, 17011102402, and 3-5100143-0 all meet specified standards. The original HM2P07PKE128GF does not specify RoHS status.

Frequently Asked Questions (FAQ)

Q: Can HM2P07PKE128GFLF be used as a direct replacement for HM2P07PKE128GF?

A: Yes. Both parts share identical electrical specifications (1.5A current rating, 750Vrms voltage rating), mechanical configuration (154 positions, 2.00mm pitch, 5+2 rows), and operating temperature range (-55°C to 125°C). The primary difference is product status: HM2P07PKE128GFLF is active while the original is obsolete.

Q: What is the difference between 154-position and 110-position alternatives?

A: The main part features 154 total positions comprising 110 signal positions and 44 dedicated ground positions arranged in 5+2 rows. The 110-position alternatives contain only signal positions in a 5-row configuration without the dedicated ground plane. Selection depends on whether the application requires the additional ground connectivity provided by the 44 ground positions.

Q: Are the TE Connectivity and HARTING 110-position parts compatible with the original 154-position design?

A: These parts are mechanically and electrically compatible for applications requiring only 110 signal positions. However, they do not provide the dedicated ground plane of the original design. Compatibility must be verified against specific application requirements.

Q: What packaging differences exist among substitute parts?

A: HM2P07PKE128GFLF is supplied in Tray packaging, PCN21B-110PB-2PF-G in Bulk, and TE Connectivity/HARTING parts in Tube packaging. Packaging selection may affect handling, storage, and integration into production workflows but does not affect electrical or mechanical performance.

Q: Which substitute part has the highest inventory availability?

A: PCN21B-110PB-2PF-G has the highest inventory at 1117 pieces, followed by 3-5100143-0 at 1050 pieces. However, inventory levels are subject to change and should be verified at time of procurement.

Q: Does voltage rating affect part selection?

A: Yes. The original HM2P07PKE128GF operates at 750Vrms, while most 110-position alternatives operate at 500Vrms. PCN21B-110PB-2PF-G operates at 300V. Applications requiring the full 750Vrms rating must use HM2P07PKE128GFLF or the original part.
