HM2H07P119LF Equivalent & Substitute Parts

Part Overview

The HM2H07P119LF is a 110-position shroud for male pins connector manufactured by Amphenol ICC (FCI) in the Millipacs® series. This through-hole hard metric Type A connector is designed for backplane applications with a 0.079" (2.00mm) pitch and 5+2 row configuration. The product is currently obsolete, making identification of compatible substitute parts essential for ongoing system maintenance and new design implementations where legacy compatibility is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the HM2H07P119LF is determined by the following critical parameters:

• Pitch: 0.079" (2.00mm) — must match exactly for mechanical and electrical compatibility
• Number of Rows: 5 + 2 configuration — required for proper board layout and connector alignment
• Mounting Type: Through Hole — determines PCB assembly process compatibility
• Connector Category: Backplane Connectors — ensures functional equivalence in system architecture
• Compliance Standards: RoHS Compliant status and MSL rating — required for regulatory and environmental requirements

The identified substitute part PCN21B-110PB-2PF-G from Hirose Electric Co Ltd meets these core substitution criteria. While this part carries additional ground positions (154 total including 44 ground positions versus 110 signal positions in the original), it maintains the same pitch, row configuration, through-hole mounting, and compliance certifications necessary for functional substitution in backplane connector applications.

Parameter Comparison

Engineering Selection Recommendations

Selection of PCN21B-110PB-2PF-G as a substitute for HM2H07P119LF is based on the following engineering criteria:

Mechanical Compatibility: Both connectors maintain identical pitch (0.079" / 2.00mm) and row configuration (5+2), ensuring direct mechanical interchangeability at the board level.

Electrical Compliance: Both parts are RoHS Compliant with MSL rating of 1 (Unlimited), meeting current regulatory requirements for electronic component procurement and assembly.

Functional Equivalence: Both are classified as backplane connectors with through-hole mounting, maintaining system-level functional requirements.

Product Status Alignment: Both parts share obsolete status, indicating they are suitable for legacy system support and maintenance applications where original component sourcing is no longer available.

Termination Difference: The substitute part features press-fit termination compared to the unspecified termination of the original part. This difference requires verification against specific PCB design requirements and assembly capabilities.

Frequently Asked Questions (FAQ)

Q: Can PCN21B-110PB-2PF-G directly replace HM2H07P119LF in existing designs?

A: Direct mechanical replacement is possible due to matching pitch (0.079" / 2.00mm) and row configuration (5+2). However, the substitute part includes additional ground positions (44 ground pins in addition to 110 signal positions). PCB layout and connector footprint must be evaluated to confirm compatibility with the increased total position count.

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

A: The PCN21B-110PB-2PF-G includes 44 dedicated ground positions integrated into the 154-position connector. The original HM2H07P119LF specifies 110 positions without ground position designation. This difference affects PCB routing and grounding strategy and must be assessed during design integration.

Q: Are both parts suitable for the same operating environment?

A: Both parts maintain MSL rating of 1 (Unlimited) and RoHS Compliance. The substitute part specifies operating temperature range of -55°C ~ 125°C and voltage rating of 300V. The original part does not provide these specifications. Environmental requirements must be confirmed against application needs.

Q: What is the difference between shroud and header connector types?

A: The original part is specified as a shroud for male pins, while the substitute is a header with male pins. Both are through-hole connectors with identical pitch and row configuration. The shroud design of the original part provides additional mechanical protection. Design requirements must determine if this feature is necessary for the application.

Q: How does press-fit termination affect assembly compatibility?

A: The substitute part uses press-fit termination, while the original part termination is not specified. Press-fit termination requires specific assembly equipment and PCB hole sizing. Existing assembly processes and PCB designs must be evaluated for compatibility with this termination method.
