HM2P09PDE121L9 Equivalent & Substitute Parts

Part Overview

The HM2P09PDE121L9 is a 77-position header connector (55 signal + 22 ground positions) manufactured by Amphenol ICC (FCI) from the Millipacs® series. This through-hole, press-fit connector operates at 0.079" (2.00mm) pitch with gold-plated contacts rated for 1.5A at 750Vrms across an operating temperature range of -55°C to 125°C.

The HM2P09PDE121L9 carries an obsolete product status. Locating equivalent or substitute components is necessary for ongoing system support, maintenance, and new production runs where this connector type is specified in legacy designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HM2P09PDE121L9 is determined by strict equivalence across the following critical parameters:

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

The HM2P09PDE121L9LF qualifies as a direct substitute because it maintains identical electrical, mechanical, and dimensional specifications while offering improved product status and regulatory compliance.

Parameter Comparison

Engineering Selection Recommendations

The HM2P09PDE121L9LF is the direct substitute for the obsolete HM2P09PDE121L9. Both connectors share identical electrical and mechanical specifications, ensuring functional compatibility in existing designs.

Selection between these parts should be based on regulatory and compliance requirements:

• HM2P09PDE121L9LF is the preferred choice for new designs and production runs. It carries Active product status, RoHS compliance, and REACH applicability, meeting current environmental and regulatory standards.

• HM2P09PDE121L9 remains available for legacy system maintenance where RoHS non-compliance is acceptable and regulatory constraints do not apply.

Packaging differences (Tray for the LF variant versus Bulk for the original) may influence procurement decisions based on order quantities and handling requirements.

Frequently Asked Questions (FAQ)

Q: Are HM2P09PDE121L9 and HM2P09PDE121L9LF electrically and mechanically interchangeable?

A: Yes. Both connectors maintain identical specifications for connector type, position count, pitch, mounting method, termination, contact finish, current rating, voltage rating, and operating temperature range. They are direct functional equivalents.

Q: What is the significance of the "LF" suffix in HM2P09PDE121L9LF?

A: The "LF" designation indicates Lead-Free construction and RoHS compliance. This variant meets current environmental regulations while maintaining all electrical and mechanical characteristics of the original part.

Q: Why is HM2P09PDE121L9 marked as obsolete?

A: Obsolete status reflects the manufacturer's discontinuation of this part number. The HM2P09PDE121L9LF serves as the active replacement, offering improved regulatory compliance and ongoing availability.

Q: Can I use HM2P09PDE121L9LF in applications originally designed for HM2P09PDE121L9?

A: Yes. The LF variant is a direct substitute with identical functional specifications. No design modifications are required.

Q: What packaging options are available?

A: HM2P09PDE121L9 is supplied in Bulk packaging, while HM2P09PDE121L9LF is supplied in Tray packaging. Packaging selection may depend on order volume and handling requirements.

Q: Are there any compliance differences between these parts?

A: HM2P09PDE121L9LF is RoHS Compliant and REACH Affected, while HM2P09PDE121L9 is RoHS Non-compliant and REACH Unaffected. For applications subject to environmental regulations, HM2P09PDE121L9LF is required.
