HM2P07PME124GL Equivalent & Substitute Parts

Part Overview

The HM2P07PME124GL is a 154-position backplane connector header manufactured by Amphenol ICC (FCI) with 0.079" (2.00mm) pitch and press-fit termination. This connector features 110 signal positions plus 44 ground positions across 5 + 2 rows, designed for through-hole mounting applications. The part is currently 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 HM2P07PME124GL is determined by the following critical parameters:

Primary Substitution Criteria:

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

Position Configuration Considerations: The HM2P07PME124GL contains 154 total positions (110 signal + 44 ground) across 5 + 2 rows. Substitutes are grouped into two categories:

1. Direct Equivalents (154-Position): Parts maintaining identical position count and row configuration
2. Functional Alternatives (110-Position): Parts with 110 positions across 5 rows, suitable where ground plane integration or external grounding is available

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: HM2P07PME124GLLF

The HM2P07PME124GLLF is the direct equivalent to HM2P07PME124GL, maintaining identical electrical and mechanical specifications while offering active product status. This part is RoHS Compliant and provides the highest voltage rating (750Vrms) among available substitutes. The only difference is packaging format (Tray vs. unspecified), which does not affect functional compatibility.

Secondary Recommendations for 154-Position Requirement:

PCN21B-110PB-2PF-G (Hirose Electric) maintains the 154-position configuration with identical pitch and termination. However, this part is obsolete and carries a lower voltage rating (300V). Selection should be based on voltage requirements of the application.

Alternative for 110-Position Applications:

When system design permits use of 110-position headers with external ground management:

• 1-5100143-9 (TE Connectivity): Active status, ROHS3 Compliant, 500Vrms rating, 1.5A current capacity
• 3-5100143-0 (TE Connectivity): Active status, RoHS Compliant, 500Vrms rating, 1.5A current capacity, 30.0µin contact finish thickness
• 17011102402 (HARTING): Active status, ROHS3 Compliant, 1.0A current capacity (lower than original specification)

The TE Connectivity parts (1-5100143-9 and 3-5100143-0) are preferred over the HARTING option due to matching current rating specifications.

Frequently Asked Questions (FAQ)

Q: Can I use a 110-position connector as a substitute for the 154-position HM2P07PME124GL?

A: Only if your application design accommodates the reduced position count. The 110-position alternatives (1-5100143-9, 3-5100143-0, 17011102402) provide signal connectivity but lack the integrated 44 ground positions. External ground plane or separate grounding provisions must be implemented.

Q: What is the difference between HM2P07PME124GL and HM2P07PME124GLLF?

A: Both parts are electrically and mechanically identical with matching pitch, position count, termination, and current rating. The primary difference is packaging: HM2P07PME124GLLF is supplied in Tray format. HM2P07PME124GLLF is active production status while HM2P07PME124GL is obsolete.

Q: Is the HARTING 17011102402 suitable as a direct replacement?

A: The HARTING part matches pitch, position count (110), mounting type, and termination. However, it specifies 1.0A current rating versus the original 1.5A specification. Selection depends on circuit current requirements. If 1.5A capacity is mandatory, TE Connectivity alternatives are preferred.

Q: What are the compliance differences between substitute options?

A: HM2P07PME124GLLF, 1-5100143-9, and 3-5100143-0 are RoHS/ROHS3 Compliant. The HARTING 17011102402 is ROHS3 Compliant. PCN21B-110PB-2PF-G is RoHS Compliant but obsolete. All parts are EAR99 classified and REACH Unaffected or Vendor Undefined.

Q: Does packaging format affect electrical performance?

A: No. Packaging differences (Tray, Tube, Bulk) do not affect connector electrical or mechanical performance. Selection should be based on procurement and handling requirements.

Q: What voltage rating should I use for design validation?

A: The original HM2P07PME124GL does not specify voltage rating. HM2P07PME124GLLF provides 750Vrms, the highest among substitutes. For conservative design, use the lowest specified rating among candidate parts (300V for PCN21B-110PB-2PF-G) or verify application voltage requirements independently.
