Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HM2P09PC5111N9 is determined by strict equivalence across the following critical parameters:

• Connector type, style, and position count (77 positions with 55 + 22 Ground configuration)
• Pitch specification (0.079" / 2.00mm)
• Row configuration (5 + 2)
• Mounting method (Through Hole)
• Termination technology (Press-Fit)
• Electrical ratings (Current and Voltage)
• Operating temperature range (-55°C ~ 125°C)
• Contact material and finish (Gold)

The HM2P09PC5111N9LF meets all these criteria and is classified as a direct substitute. Both parts share the same base product number (HM2P09) and connector style (C 11), confirming functional and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The HM2P09PC5111N9LF is the direct substitute for the obsolete HM2P09PC5111N9. Both parts maintain identical mechanical and electrical specifications across all critical parameters. The HM2P09PC5111N9LF offers the following advantages:

• Active product status ensures ongoing availability and supply chain continuity
• RoHS compliance aligns with current environmental and regulatory standards
• Higher voltage rating (750Vrms vs. 500V) provides additional design margin
• Tray packaging supports standard procurement and handling workflows

Selection of the HM2P09PC5111N9LF eliminates obsolescence risk while maintaining full functional compatibility with existing designs.

Frequently Asked Questions (FAQ)

Q: Can HM2P09PC5111N9LF be used as a direct replacement for HM2P09PC5111N9?

A: Yes. Both parts are mechanically and electrically equivalent across all critical parameters: position count, pitch, row configuration, mounting type, termination method, current rating, and operating temperature range. The HM2P09PC5111N9LF is the active production equivalent.

Q: What is the difference between these two part numbers?

A: The primary differences are product status, compliance certifications, and packaging. The HM2P09PC5111N9LF is RoHS compliant and active in production, while the HM2P09PC5111N9 is obsolete and non-compliant. The HM2P09PC5111N9LF also features a higher voltage rating (750Vrms) and comes in tray packaging.

Q: Are there any compatibility concerns when switching from HM2P09PC5111N9 to HM2P09PC5111N9LF?

A: No compatibility concerns exist. The connector style (C 11), pin configuration, pitch, and all electrical ratings remain identical. PCB footprints and mating connectors designed for the original part will function without modification.

Q: What does the "LF" suffix in HM2P09PC5111N9LF indicate?

A: The "LF" suffix indicates lead-free compliance, reflecting the part's RoHS compliance status and environmental standards adherence.

Q: Is the higher voltage rating of HM2P09PC5111N9LF a concern for existing designs?

A: No. A higher voltage rating (750Vrms vs. 500V) is a superset capability and does not affect operation in circuits designed for the original 500V specification. This provides additional design margin.
