HM2P66PKF2W5GF Equivalent & Substitute Parts

Part Overview

The HM2P66PKF2W5GF is a 146-position backplane connector header manufactured by Amphenol ICC (FCI) in the Millipacs® series. This through-hole press-fit connector features a 2.00mm pitch and is designed for high-density interconnect applications. The main part is currently obsolete, making equivalent and substitute parts necessary for ongoing system support and new designs requiring compatible interconnect solutions.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HM2P66PKF2W5GF is determined by the following critical parameters:

• Pitch (2.00mm): All substitute parts must maintain identical 2.00mm pitch spacing for PCB compatibility
• Mounting Type (Through Hole): All substitutes must use through-hole mounting
• Termination (Press-Fit): All substitutes must use press-fit termination technology
• Connector Type (Header, Male Pins): All substitutes must be male pin headers
• Current Rating (1.5 A minimum): Substitutes must support at least 1.5 A per contact
• Voltage Rating (500Vrms minimum): Substitutes must support minimum 500Vrms
• Operating Temperature (-55°C ~ 125°C): Substitutes must cover this temperature range

Substitutes are grouped into two categories: direct equivalents (same position count and ground configuration) and functional alternatives (different position counts but compatible electrical and mechanical specifications).

Parameter Comparison

Engineering Selection Recommendations

HM2P66PKF2W5GFLF is the direct equivalent substitute for HM2P66PKF2W5GF. Both parts share identical electrical and mechanical specifications with 146 positions (110 + 36 ground), 5 + 2 row configuration, and 2.00mm pitch. The primary difference is product status: HM2P66PKF2W5GFLF is active and RoHS compliant, whereas the main part is obsolete and non-compliant. This substitute is recommended for new designs and ongoing production requiring direct form-fit-function replacement.

5352132-1 (TE Connectivity Z-PACK series) is a functional alternative with reduced position count (110 positions, 5 rows only). This part maintains all critical electrical parameters (1.5 A current rating, -55°C ~ 125°C operating range) and mechanical specifications (2.00mm pitch, through-hole press-fit). The voltage rating is 500Vrms, which meets minimum requirements but is lower than the main part. This substitute is suitable for applications where the full 146-position configuration is not required and where the 500Vrms rating is acceptable.

CP2-HAB110-GA1-FJ (3M MetPak™ CP2 series) is a functional alternative with 154 positions (110 + 44 ground) in a 5 + 2 row configuration. This part maintains 2.00mm pitch and through-hole press-fit termination. Current and voltage ratings are not specified in available documentation. This substitute is suitable for applications requiring higher ground pin density and is designed for CompactPCI hot-swap environments.

All substitute parts are RoHS compliant and active products, providing long-term availability compared to the obsolete main part.

Frequently Asked Questions (FAQ)

Q: Can HM2P66PKF2W5GFLF be used as a direct replacement for HM2P66PKF2W5GF?

A: Yes. HM2P66PKF2W5GFLF is a direct equivalent with identical position count (146), row configuration (5 + 2), pitch (2.00mm), and electrical ratings (1.5 A, 750Vrms). The primary difference is product status and RoHS compliance. Both parts are mechanically and electrically interchangeable.

Q: What is the difference between the main part and its substitutes in terms of position count?

A: The main part HM2P66PKF2W5GF and its direct equivalent HM2P66PKF2W5GFLF both have 146 positions (110 signal + 36 ground). The 5352132-1 substitute has 110 positions (signal only, 5 rows), and the CP2-HAB110-GA1-FJ has 154 positions (110 signal + 44 ground). Position count affects PCB layout and connector footprint.

Q: Are all substitutes compatible with the same PCB footprint?

A: No. While all parts share 2.00mm pitch and through-hole mounting, different position counts and row configurations require different PCB footprints. HM2P66PKF2W5GFLF uses the same footprint as the main part. The 5352132-1 requires a smaller footprint (5 rows instead of 5 + 2). The CP2-HAB110-GA1-FJ requires a different footprint due to its 154-position configuration.

Q: What are the voltage rating differences among substitutes?

A: The main part and HM2P66PKF2W5GFLF are rated for 750Vrms. The 5352132-1 is rated for 500Vrms. The CP2-HAB110-GA1-FJ voltage rating is not specified. For applications requiring 750Vrms, only the main part or HM2P66PKF2W5GFLF are suitable.

Q: Are all substitutes RoHS compliant?

A: HM2P66PKF2W5GFLF, 5352132-1, and CP2-HAB110-GA1-FJ are all RoHS compliant. The main part HM2P66PKF2W5GF is RoHS non-compliant. For applications requiring RoHS compliance, any of the three substitutes are acceptable.

Q: What packaging options are available for these parts?

A: HM2P66PKF2W5GF packaging is not specified. HM2P66PKF2W5GFLF is supplied in trays. 5352132-1 is supplied in tubes. CP2-HAB110-GA1-FJ packaging is not specified. Packaging affects handling, storage, and automated assembly compatibility.
