HM2P66PDF2X5N9 Equivalent & Substitute Parts

Part Overview

The HM2P66PDF2X5N9 is a 146-position (110 + 36 ground) header connector manufactured by Amphenol ICC (FCI) in the Millipacs® series. This press-fit through-hole connector operates at 0.079" (2.00mm) pitch with gold-plated contacts rated for 1.5A at 750Vrms across -55°C to 125°C. The part is currently obsolete, making equivalent substitutes necessary for ongoing system support and new designs requiring compatible backplane connector solutions.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HM2P66PDF2X5N9 is determined by the following critical parameters:

• Position Count & Ground Configuration: 146 positions (110 + 36 ground) or functionally equivalent
• Pitch: 0.079" (2.00mm) mandatory
• Connector Style: AB 22 configuration
• Mounting & Termination: Through-hole press-fit only
• Contact Finish: Gold plating
• Current & Voltage Ratings: Minimum 1.5A and 500Vrms (original rated 750Vrms)
• Temperature Range: -55°C ~ 125°C
• RoHS & Compliance Status: Active product status preferred; RoHS compliance required for new designs

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

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: HM2P66PDF2X5N9LF

The HM2P66PDF2X5N9LF is the direct equivalent replacement. It maintains identical electrical and mechanical specifications (146 positions, AB 22 style, 5 + 2 rows, 750Vrms rating) while offering active product status and RoHS compliance. This part is the preferred choice for direct replacement in existing designs.

Secondary Substitute: 5646533-1 (TE Connectivity)

The 5646533-1 provides identical position count and connector style (146 positions, AB 22, 5 + 2 rows) with active status and RoHS compliance. The voltage rating is reduced to 500Vrms; this part is suitable for applications not requiring the full 750Vrms specification. Gold contact finish thickness is specified at 30.0µin.

Functional Alternative: 5352132-1 (TE Connectivity)

The 5352132-1 reduces position count to 110 (single row configuration, B 22 style) while maintaining 1.5A current rating and -55°C to 125°C temperature range. This part is applicable only when the 110-position configuration meets system requirements. Voltage rating is 500Vrms.

Functional Alternative: CP2-HAB110-GA1-FJ (3M)

The CP2-HAB110-GA1-FJ increases position count to 154 (110 + 44 ground) in AB 22 style with 5 + 2 rows. This part is suitable for designs requiring additional ground positions. Voltage and current ratings are not specified; compatibility must be confirmed against application requirements.

Frequently Asked Questions (FAQ)

Q: Can HM2P66PDF2X5N9LF be used as a direct replacement for HM2P66PDF2X5N9?

A: Yes. The HM2P66PDF2X5N9LF is electrically and mechanically identical, with the primary difference being active product status and RoHS compliance. It is the recommended direct substitute.

Q: What is the difference between the Amphenol and TE Connectivity versions?

A: Both maintain the 146-position, AB 22 configuration and 2.00mm pitch. The TE Connectivity 5646533-1 operates at 500Vrms versus the original 750Vrms rating. Connector series differ (Millipacs® versus Z-PACK), but electrical and mechanical compatibility is maintained.

Q: Can 5352132-1 be used in place of HM2P66PDF2X5N9?

A: Only if the application requires 110 positions instead of 146. The 5352132-1 uses a B 22 connector style (single row configuration) rather than AB 22 (5 + 2 rows). Physical and electrical compatibility must be confirmed for the specific PCB layout and backplane design.

Q: What does the voltage rating difference (750Vrms vs. 500Vrms) mean for substitution?

A: The original part is rated for 750Vrms. Substitutes rated at 500Vrms are suitable for applications operating at or below 500Vrms. If the system requires 750Vrms operation, only HM2P66PDF2X5N9 or HM2P66PDF2X5N9LF are appropriate.

Q: Are all substitutes RoHS compliant?

A: HM2P66PDF2X5N9LF, 5646533-1, 5352132-1, and CP2-HAB110-GA1-FJ are all RoHS compliant. The original HM2P66PDF2X5N9 is non-compliant. For new designs or regulated applications, RoHS-compliant substitutes are required.

Q: What packaging options are available?

A: HM2P66PDF2X5N9LF is supplied in trays; 5646533-1 and 5352132-1 are supplied in tubes; HM2P66PDF2X5N9 and CP2-HAB110-GA1-FJ are supplied in bulk. Packaging selection depends on assembly process requirements and inventory management.

Q: Can CP2-HAB110-GA1-FJ be used as a substitute despite having 154 positions?

A: Only if the application design accommodates the increased position count (154 vs. 146). The additional 8 ground positions may require PCB layout modifications. Electrical compatibility must be confirmed, as voltage and current ratings are not specified for this part.
