HM2P66PMG2H4GLLF Equivalent & Substitute Parts

Part Overview

The HM2P66PMG2H4GLLF is a 146-position backplane connector header manufactured by Amphenol ICC (FCI) in the Millipacs® series. This press-fit through-hole connector features 110 signal positions plus 36 ground positions arranged in a 5+2 row configuration with 2.00mm pitch. The connector is designed for high-density interconnect applications requiring robust electrical performance and thermal stability across industrial temperature ranges.

This part is currently active in production with 716 units in stock. Alternative part numbers may be required due to inventory constraints, application-specific requirements, or design revisions necessitating compatible substitutes that maintain electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HM2P66PMG2H4GLLF is determined by the following critical parameters:

Pitch (0.079" / 2.00mm): All substitute parts must maintain identical pitch spacing to ensure mechanical compatibility with mating connectors and PCB layouts.

Mounting Type (Through Hole) and Termination (Press-Fit): Substitute parts must use identical mounting and termination methods to ensure compatibility with existing PCB designs and assembly processes.

Connector Type (Header, Male Pins): Substitute parts must maintain the same connector gender and pin configuration.

Current Rating (1.5 A minimum) and Voltage Rating (500Vrms minimum): Substitute parts must meet or exceed the electrical performance requirements of the original specification.

Operating Temperature Range (-55°C ~ 125°C): Substitute parts must support the full operating temperature range.

RoHS and REACH Compliance: Substitute parts must maintain equivalent environmental compliance status.

The substitute part 5352639-1 (TE Connectivity AMP Connectors, Z-PACK series) qualifies as an equivalent based on these parameters, though with a reduced position count (110 vs. 146) and lower voltage rating (500Vrms vs. 750Vrms).

Parameter Comparison

Engineering Selection Recommendations

Both the HM2P66PMG2H4GLLF and 5352639-1 are active production parts with current inventory availability. Both maintain full compliance with RoHS and REACH environmental standards, ensuring regulatory compatibility for industrial and commercial applications.

The HM2P66PMG2H4GLLF provides higher position density (146 positions) and elevated voltage rating (750Vrms), making it suitable for applications requiring maximum signal routing capacity and higher voltage isolation margins.

The 5352639-1 provides a reduced-position alternative (110 positions) with equivalent current rating and temperature range. This substitute is suitable for applications where the full 146-position configuration is not required and where the 500Vrms voltage rating is sufficient for the intended application.

Selection between these parts should be based on specific application requirements for position count and voltage rating. Both parts share identical pitch, mounting type, termination method, and current rating, ensuring mechanical and electrical compatibility within their respective electrical specifications.

Frequently Asked Questions (FAQ)

Q: Can 5352639-1 be used as a direct replacement for HM2P66PMG2H4GLLF?

A: The 5352639-1 is mechanically compatible due to identical pitch (2.00mm), mounting type (through hole), and termination method (press-fit). However, it provides only 110 positions compared to 146 positions in the original part, and has a lower voltage rating (500Vrms vs. 750Vrms). Substitution is valid only if the application requires 110 or fewer signal positions and operates at or below 500Vrms.

Q: What are the key differences in position configuration?

A: The HM2P66PMG2H4GLLF features 146 total positions (110 signal + 36 ground) arranged in 5+2 rows. The 5352639-1 features 110 positions arranged in 5 rows. The reduced ground pin count in the substitute may affect grounding distribution in high-frequency or high-current applications.

Q: Are both parts RoHS compliant?

A: Yes. The HM2P66PMG2H4GLLF is RoHS Compliant, and the 5352639-1 is ROHS3 Compliant. Both meet current environmental regulations for hazardous substance restrictions.

Q: What is the difference in packaging between these parts?

A: The HM2P66PMG2H4GLLF is supplied in Tray packaging, while the 5352639-1 is supplied in Tube packaging. Packaging format may affect handling, storage, and assembly line integration but does not impact electrical or mechanical performance.

Q: Do both parts support the same operating temperature range?

A: Yes. Both the HM2P66PMG2H4GLLF and 5352639-1 operate across the full range of -55°C to 125°C, ensuring thermal compatibility for industrial applications.

Q: What is the current rating for both connectors?

A: Both parts are rated for 1.5 A per contact, providing identical current-carrying capacity for signal and power distribution applications.
