HM2H07P130LF Equivalent & Substitute Parts

Part Overview

The HM2H07P130LF is a 110-position shroud for male pins connector manufactured by Amphenol ICC (FCI) in the Millipacs® series. This hard metric, type A backplane connector features through-hole mounting and is designed for header applications with a 0.079" (2.00mm) pitch across 5 + 2 rows. The product is obsolete, making identification of compatible substitute components essential for ongoing system maintenance and new design implementations where legacy compatibility is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the HM2H07P130LF is determined by the following critical parameters that must align for functional compatibility:

Primary Substitution Criteria:

• Pitch: 0.079" (2.00mm) — maintains mechanical and electrical spacing
• Number of Rows: 5 + 2 — preserves connector geometry and layout
• Mounting Type: Through Hole — ensures PCB integration compatibility
• Connector Category: Backplane Connectors — maintains application suitability

Secondary Compatibility Factors:

• RoHS Compliance and MSL Rating — ensures regulatory and environmental compatibility
• Connector Style and Type — supports mechanical fit within shroud and header configurations

The identified substitute, PCN21B-110PB-2PF-G from Hirose Electric Co Ltd, meets these criteria with 154 total positions (110 signal + 44 ground), maintaining the 0.079" (2.00mm) pitch and 5 + 2 row configuration across through-hole mounting. The addition of ground positions provides enhanced signal integrity without compromising mechanical or electrical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Selection between the HM2H07P130LF and PCN21B-110PB-2PF-G should be based on the following engineering factors:

Obsolescence Consideration: Both components are obsolete. The PCN21B-110PB-2PF-G offers superior availability (1117 pcs in stock versus 690 pcs) and represents the manufacturer-recommended substitute, making it the preferred choice for new procurement and system redesigns.

Compliance Alignment: Both parts maintain RoHS compliance and MSL 1 rating, ensuring regulatory compatibility and eliminating moisture sensitivity constraints during storage and handling.

Electrical Performance: The PCN21B-110PB-2PF-G provides specified electrical ratings (300V, 1.5A per contact, -55°C ~ 125°C operating range) that exceed typical backplane connector requirements. The addition of 44 dedicated ground positions enhances signal integrity and EMI performance compared to the signal-only configuration of the HM2H07P130LF.

Mechanical Integration: Identical pitch (0.079" / 2.00mm), row configuration (5 + 2), and through-hole mounting ensure direct mechanical compatibility. The press-fit termination of the substitute provides improved contact reliability over traditional soldering methods.

Frequently Asked Questions (FAQ)

Q: Can PCN21B-110PB-2PF-G directly replace HM2H07P130LF in existing designs?

A: Yes, for applications requiring the 110 signal positions. The identical pitch, row configuration, and through-hole mounting ensure mechanical compatibility. The additional 44 ground positions in the substitute do not interfere with signal pin placement and may improve system performance through enhanced grounding.

Q: What is the significance of the 44 additional ground positions in the substitute?

A: The PCN21B-110PB-2PF-G integrates 44 dedicated ground positions within the same physical footprint and row structure. These ground pins provide direct grounding paths, reducing loop inductance and improving signal integrity in high-speed backplane applications.

Q: Are there differences in mounting or soldering requirements?

A: The PCN21B-110PB-2PF-G uses press-fit termination, whereas the HM2H07P130LF termination method is not specified. Press-fit technology provides consistent contact force and eliminates solder joint variability, potentially improving long-term reliability.

Q: Do both parts meet the same environmental and compliance standards?

A: Yes. Both components are RoHS compliant with MSL 1 rating (unlimited moisture sensitivity protection). Both carry EAR99 ECCN classification. The substitute provides specified operating temperature range (-55°C ~ 125°C) and voltage rating (300V), ensuring suitability across standard industrial and commercial applications.

Q: Why is the substitute listed as obsolete if it is recommended?

A: Both components are obsolete products. The PCN21B-110PB-2PF-G is designated as the manufacturer-recommended substitute despite its obsolete status, indicating it remains the most compatible alternative for legacy system support and represents the final generation of this connector family before discontinuation.
