Key Parameters

Substitute Part Grouping Explanation

Substitution for the HM2R10PA5101N9 is determined by strict equivalence across the following critical parameters:

• Connector type and style (Receptacle, Female Sockets, Style A 22)
• Position count and row configuration (110 positions, 5 rows)
• Pitch specification (0.079" / 2.00mm)
• Mounting and termination method (Board Edge, Through Hole, Right Angle, Press-Fit)
• Electrical ratings (Current and voltage capacity)
• Operating temperature range (-55°C ~ 125°C)
• Contact finish specification (Gold plating)
• Shielding configuration (Upper and Lower Shield)

The identified substitute maintains identical mechanical and electrical characteristics while differing in product status and regulatory compliance classification.

Parameter Comparison

Engineering Selection Recommendations

The HM2R10PA5101N9LF is the direct active substitute for the obsolete HM2R10PA5101N9. Both connectors are mechanically and electrically equivalent across all critical parameters. The substitute offers the following advantages:

• Active product status with current manufacturing support
• RoHS compliance, meeting modern regulatory requirements
• REACH compliance classification
• Higher voltage rating (750Vrms versus 500V), providing additional margin in applications within the original specification
• Tray packaging for standard component handling

Selection of HM2R10PA5101N9LF is appropriate for new designs and replacement applications where regulatory compliance is required. The higher voltage rating does not affect compatibility with systems designed for the original part.

Frequently Asked Questions (FAQ)

Q: Are HM2R10PA5101N9 and HM2R10PA5101N9LF mechanically interchangeable?

A: Yes. Both connectors share identical mechanical specifications: 110 positions, 0.079" pitch, 5-row configuration, board edge mounting, and right-angle orientation. Physical installation and PCB footprint are identical.

Q: What is the significance of the "LF" suffix in HM2R10PA5101N9LF?

A: The "LF" designation indicates lead-free construction and RoHS compliance. This reflects the manufacturing process and material composition rather than functional or electrical differences.

Q: Can HM2R10PA5101N9LF be used in applications originally designed for HM2R10PA5101N9?

A: Yes. The substitute maintains all critical electrical parameters (current rating, operating temperature range, contact finish) and exceeds the voltage specification. No design modifications are required.

Q: What is the difference in voltage rating between the two parts?

A: HM2R10PA5101N9 is rated at 500V, while HM2R10PA5101N9LF is rated at 750Vrms. Applications operating within the original 500V specification remain fully compatible with the substitute.

Q: Are there packaging differences between these parts?

A: The original part has unspecified packaging, while HM2R10PA5101N9LF is supplied in tray packaging. This affects handling and storage but does not impact electrical or mechanical performance.

Q: Why is HM2R10PA5101N9 classified as obsolete?

A: Obsolescence reflects the manufacturer's discontinuation of this specific configuration. HM2R10PA5101N9LF represents the current active equivalent within the Millipacs® product line.
