HM2P87PDF1P1N9LF Equivalent & Substitute Parts

Part Overview

The HM2P87PDF1P1N9LF is a 220-position backplane connector header manufactured by Amphenol ICC (FCI) in the Millipacs® series. This through-hole press-fit connector features 176 signal positions plus 44 dedicated ground positions arranged in an 8+2 row configuration with 2.00mm pitch. The connector is actively produced and RoHS compliant, designed for applications requiring high-density interconnection with robust electrical performance across industrial temperature ranges.

Substitute parts are identified when equivalent electrical and mechanical parameters align with the main part's core specifications, enabling direct functional replacement in compatible applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HM2P87PDF1P1N9LF is determined by strict alignment of the following critical parameters:

• Connector type (Header, Male Pins)
• Pitch specification (0.079" / 2.00mm)
• Mounting method (Through Hole)
• Termination technology (Press-Fit)
• Electrical ratings (Current: 1.5 A minimum; Voltage: 750Vrms minimum)
• Operating temperature range (-55°C to 125°C minimum)
• Contact finish and thickness (Gold plating)
• Connector style (D 22)

The identified substitute part 646346-1 maintains compatibility across these core parameters. The primary difference is position count: the substitute provides 176 positions in an 8-row configuration versus the main part's 220 positions (176 + 44 ground) in an 8+2 configuration. This distinction is critical for application-specific compatibility assessment.

Parameter Comparison

Engineering Selection Recommendations

Both the HM2P87PDF1P1N9LF and 646346-1 maintain active product status and meet identical electrical and thermal specifications. The HM2P87PDF1P1N9LF carries explicit RoHS compliance certification, while the 646346-1 status is listed as not applicable. Both parts are REACH affected and classified under ECCN EAR99.

Selection between these parts depends on position count requirements. The HM2P87PDF1P1N9LF provides 220 total positions with dedicated ground rows, while 646346-1 provides 176 positions without segregated ground rows. Applications requiring the full 220-position configuration with integrated ground distribution must use the main part. Applications compatible with 176-position headers may use either part, subject to PCB layout and connector receptacle compatibility verification.

Frequently Asked Questions (FAQ)

Q: Can 646346-1 directly replace HM2P87PDF1P1N9LF in all applications?

A: Direct replacement is possible only in applications where 176 positions satisfy functional requirements and the PCB receptacle is designed for 176-position headers. The main part's additional 44 ground positions and 8+2 row configuration cannot be replicated by the 176-position substitute.

Q: What are the key electrical compatibility factors?

A: Both parts share identical current rating (1.5 A), voltage rating (750Vrms), operating temperature range (-55°C to 125°C), and contact finish specifications. Electrical performance is equivalent across these parameters.

Q: Does packaging format affect electrical performance?

A: No. The main part ships in trays while the substitute ships in tubes. Packaging format does not affect connector electrical or mechanical performance, only handling and storage logistics.

Q: Are there RoHS compliance differences?

A: The HM2P87PDF1P1N9LF is explicitly RoHS compliant. The 646346-1 lists RoHS status as not applicable. Applications with RoHS compliance requirements must use the main part or confirm substitute compliance through the manufacturer.

Q: What pitch specification applies to both parts?

A: Both connectors operate at 0.079" (2.00mm) pitch, ensuring mechanical compatibility with receptacles designed for this standard spacing.
