Key Parameters

Substitute Part Grouping Explanation

Substitution for the HM2P09PDP291N9 is determined by strict equivalence across the following parameters:

• Connector type and style (Header, Male Pins, C 11 style)
• Position count and configuration (77 positions: 55 + 22 Ground)
• Pitch specification (0.079" / 2.00mm)
• Row configuration (5 + 2)
• Mounting and termination method (Through Hole, Press-Fit)
• Electrical ratings (1.5 A current, 750Vrms voltage)
• Operating temperature range (-55°C ~ 125°C)
• Contact finish specification (Gold, Flash thickness)
• Board guide feature presence

The HM2P09PDP291N9LF meets all these criteria and is classified as a direct manufacturer equivalent.

Parameter Comparison

Engineering Selection Recommendations

The HM2P09PDP291N9LF is the direct functional equivalent of the obsolete HM2P09PDP291N9. Both parts share identical electrical, mechanical, and dimensional specifications. The primary differences are product status and regulatory compliance:

The HM2P09PDP291N9LF carries Active product status and RoHS Compliant certification, making it the appropriate selection for new designs and ongoing production. The original part's obsolete status and RoHS non-compliant designation indicate it is no longer manufactured or supported by Amphenol ICC (FCI).

For applications requiring the HM2P09PDP291N9, the HM2P09PDP291N9LF provides full functional compatibility with improved regulatory standing. The tray packaging of the substitute part is standard for active production inventory.

Frequently Asked Questions (FAQ)

Q: Are HM2P09PDP291N9 and HM2P09PDP291N9LF mechanically interchangeable?

A: Yes. Both parts share identical connector type, position count (77), pitch (2.00mm), row configuration (5 + 2), mounting method (Through Hole), and termination type (Press-Fit). They are mechanically and electrically interchangeable.

Q: What is the significance of the "LF" suffix in HM2P09PDP291N9LF?

A: The "LF" designation indicates Lead-Free composition, which aligns with RoHS compliance requirements. This is the primary distinction between the two part numbers.

Q: Can the HM2P09PDP291N9LF be used as a direct replacement in existing designs?

A: Yes. The HM2P09PDP291N9LF maintains all electrical ratings (1.5 A, 750Vrms), operating temperature range (-55°C ~ 125°C), and mechanical specifications of the original part. No design modifications are required.

Q: What packaging is available for the HM2P09PDP291N9LF?

A: The HM2P09PDP291N9LF is supplied in Tray packaging, which is standard for active production components.

Q: Why is the original HM2P09PDP291N9 marked as obsolete?

A: The original part is no longer manufactured by Amphenol ICC (FCI). The HM2P09PDP291N9LF has replaced it in the active product line, offering improved regulatory compliance and continued manufacturing support.
