HM2P66PDF2X5N9LF Equivalent & Substitute Parts

Part Overview

The HM2P66PDF2X5N9LF is a 146-position header connector manufactured by Amphenol ICC (FCI) within the Millipacs® series. This backplane connector features male pins with a 2.00mm pitch and press-fit termination for through-hole mounting. The connector accommodates 110 signal positions plus 36 ground positions across 5 rows plus 2 additional rows, operating across a temperature range of -55°C to 125°C with a 750Vrms voltage rating. As an active product with full RoHS compliance and MSL 1 rating, equivalent alternatives may be required for supply chain optimization, design flexibility, or specific application requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HM2P66PDF2X5N9LF is determined by the following critical parameters:

• Pitch: 0.079" (2.00mm) — must match exactly
• Mounting Type: Through Hole with Press-Fit termination
• Connector Type: Header with Male Pins
• Contact Finish: Gold plating
• Current Rating: 1.5 A minimum
• Voltage Rating: 500Vrms minimum
• Operating Temperature Range: -55°C ~ 125°C
• RoHS Compliance: Required
• MSL Rating: 1 (Unlimited)

The substitute part 5352132-1 (TE Connectivity AMP Connectors, Z-PACK series) meets these core electrical and mechanical requirements. However, the substitute accommodates 110 positions across 5 rows, compared to the main part's 146 positions across 5 + 2 rows. This difference in position count and row configuration represents a functional reduction and requires application-level verification for compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the HM2P66PDF2X5N9LF and 5352132-1 are active products with full RoHS compliance and MSL 1 ratings, ensuring regulatory alignment and supply chain stability. Both connectors maintain identical operating temperature ranges (-55°C to 125°C), current ratings (1.5 A), and press-fit termination methodology.

The primary distinction lies in position capacity and voltage rating. The HM2P66PDF2X5N9LF provides 146 positions with a 750Vrms rating, while the 5352132-1 provides 110 positions with a 500Vrms rating. Selection between these parts depends on whether the application requires the full 146-position capacity and 750Vrms voltage specification. If the application requires fewer than 110 positions and operates below 500Vrms, the 5352132-1 represents a functionally equivalent alternative. If the application requires all 146 positions or operates above 500Vrms, the HM2P66PDF2X5N9LF is the appropriate choice.

Frequently Asked Questions (FAQ)

Q: Can the 5352132-1 be used as a direct replacement for the HM2P66PDF2X5N9LF?

A: The 5352132-1 is electrically and mechanically compatible in terms of pitch (2.00mm), termination method (press-fit), connector type (header, male pins), and operating temperature range. However, it provides only 110 positions compared to 146 positions in the main part, and its voltage rating is 500Vrms versus 750Vrms. Direct substitution is possible only if the application uses 110 or fewer positions and operates at or below 500Vrms.

Q: What are the critical parameters that determine substitution compatibility?

A: Substitution compatibility is determined by pitch (0.079" / 2.00mm), mounting type (through hole), termination method (press-fit), connector type (header, male pins), contact finish (gold), current rating (1.5 A minimum), voltage rating (500Vrms minimum), operating temperature range (-55°C to 125°C), and compliance certifications (RoHS, MSL 1).

Q: Are there packaging differences between these parts?

A: Yes. The HM2P66PDF2X5N9LF is supplied in Tray packaging, while the 5352132-1 is supplied in Tube packaging. Packaging differences may affect handling, storage, and integration into assembly processes but do not affect electrical or mechanical performance.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both the HM2P66PDF2X5N9LF and 5352132-1 are RoHS Compliant with MSL 1 (Unlimited) ratings. Both are classified under ECCN EAR99 and HTSUS 8536.69.4040. The HM2P66PDF2X5N9LF carries REACH Affected status, while the 5352132-1 shows Vendor Undefined REACH status.

Q: What is the significance of the 146-position configuration in the main part?

A: The HM2P66PDF2X5N9LF accommodates 110 signal positions plus 36 dedicated ground positions across 5 rows plus 2 additional rows. This configuration provides enhanced grounding capability and signal integrity for high-density backplane applications. The 5352132-1 provides 110 total positions across 5 rows without the dedicated ground row structure.
