HM2P70PKE124GLLF Equivalent & Substitute Parts

Part Overview

The HM2P70PKE124GLLF is a 154-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 supports 1.5A current at 750Vrms, operating across -55°C to 125°C. The connector is RoHS compliant and carries an MSL rating of 1 (Unlimited). As an active product with current inventory availability, substitute parts may be required for design flexibility, supply chain optimization, or specific application requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HM2P70PKE124GLLF is determined by the following critical parameters:

• Connector Type: Header, Male Pins
• Pitch: 0.079" (2.00mm)
• Mounting Type: Through Hole
• Termination: Press-Fit
• Current Rating: 1.5 A minimum
• Voltage Rating: 500Vrms minimum
• Operating Temperature Range: -55°C ~ 125°C
• Contact Finish: Gold
• RoHS Compliance: Required

The substitute part 5352132-1 (TE Connectivity AMP Connectors, Z-PACK series) meets these core electrical and mechanical criteria. However, the substitute differs in position count (110 vs. 154) and row configuration (5 vs. 5 + 2), which affects physical layout and ground distribution. The voltage rating of the substitute (500Vrms) is lower than the main part (750Vrms), representing a functional constraint for high-voltage applications.

Parameter Comparison

Engineering Selection Recommendations

Selection between the HM2P70PKE124GLLF and 5352132-1 must account for the following factors based on provided specifications:

Both parts are active products with RoHS compliance and MSL 1 ratings, ensuring regulatory and environmental compatibility. The primary differentiator is voltage rating: the main part supports 750Vrms while the substitute supports 500Vrms. Applications requiring voltages above 500Vrms must use the HM2P70PKE124GLLF.

Position count and row configuration differ significantly. The main part provides 154 positions across 5 + 2 rows with integrated ground distribution, while the substitute provides 110 positions across 5 rows. PCB layout and signal routing requirements must align with these physical differences.

Both connectors share identical pitch (2.00mm), current rating (1.5A), temperature range (-55°C to 125°C), and press-fit termination, ensuring mechanical and thermal compatibility within these parameters.

Frequently Asked Questions (FAQ)

Q: Can 5352132-1 replace HM2P70PKE124GLLF in all applications?

A: No. The substitute is suitable only for applications operating at 500Vrms or below. Applications requiring 750Vrms operation must use the main part. Additionally, the reduced position count (110 vs. 154) and different row configuration (5 vs. 5 + 2) require PCB redesign.

Q: What are the key electrical compatibility criteria?

A: Both parts share 1.5A current rating, 2.00mm pitch, gold contact finish, and -55°C to 125°C operating range. The voltage rating is the critical differentiator: 750Vrms (main) vs. 500Vrms (substitute).

Q: How do position count differences affect substitution?

A: The main part provides 154 positions with dedicated ground rows, while the substitute provides 110 positions. This affects signal density, ground distribution, and PCB layout. Direct substitution without layout modification is not possible.

Q: Are both parts RoHS compliant?

A: Yes. Both HM2P70PKE124GLLF and 5352132-1 are RoHS compliant with MSL 1 (Unlimited) ratings.

Q: What packaging differences exist?

A: The main part is supplied in Tray packaging, while the substitute is supplied in Tube packaging. This affects handling and storage but does not impact electrical or mechanical performance.

Q: Can these connectors be used interchangeably on the same PCB?

A: No. The different position counts, row configurations, and physical layouts require separate PCB designs. Mechanical and electrical redesign is necessary for substitution.
