HM2P82PKA1M1GF Equivalent & Substitute Parts

Part Overview

The HM2P82PKA1M1GF is a 110-position backplane connector header manufactured by Amphenol ICC (FCI) in the Millipacs® series. This press-fit through-hole connector features 88 signal positions plus 22 ground positions with 0.079" (2.00mm) pitch and supports 1.5A current at 750Vrms. The part is currently listed as obsolete, making identification of equivalent and substitute components essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HM2P82PKA1M1GF is determined by the following critical parameters:

Primary Compatibility Criteria:

• Connector type: Header, Male Pins
• Pitch: 0.079" (2.00mm)
• Mounting type: Through Hole
• Termination method: Press-Fit
• Current rating: 1.5 A minimum
• Voltage rating: 750Vrms minimum
• Operating temperature range: -55°C ~ 125°C
• Contact finish: Gold

Position Configuration Consideration: The main part contains 110 total positions (88 signal + 22 ground) arranged in 8 + 2 rows. Substitute parts may differ in total position count while maintaining the same pitch, row structure, and electrical characteristics. The 5646457-1 substitute contains 88 positions in 8 rows, representing a reduced-position variant suitable for applications requiring fewer signal channels.

Parameter Comparison

Engineering Selection Recommendations

HM2P82PKA1M1GFLF (Direct Amphenol ICC Substitute): This part is the active production equivalent of the obsolete HM2P82PKA1M1GF. Both parts maintain identical position counts (110), row configuration (8 + 2), and electrical specifications. The primary differences are product status (active vs. obsolete), RoHS compliance (compliant vs. non-compliant), and contact finish thickness (flash vs. 30.0µin). This substitute is the preferred choice for direct replacement in new designs and ongoing production requiring the same 110-position configuration.

5646457-1 (TE Connectivity Z-PACK Substitute): This part provides an alternative from a different manufacturer with reduced position count (88 positions, 8 rows). It maintains all critical electrical parameters: 0.079" pitch, 1.5A current rating, 750Vrms voltage rating, and -55°C to 125°C operating range. This substitute is applicable only for applications that do not require the full 110-position capacity or the dedicated ground row configuration of the original part. Both the HM2P82PKA1M1GFLF and 5646457-1 are RoHS compliant and in active production status.

Frequently Asked Questions (FAQ)

Q: Can HM2P82PKA1M1GFLF be used as a direct replacement for HM2P82PKA1M1GF? A: Yes. Both parts share identical position counts (110), row configuration (8 + 2), pitch (0.079"), mounting type (through hole), termination method (press-fit), and electrical ratings (1.5A, 750Vrms, -55°C to 125°C). The HM2P82PKA1M1GFLF is the active production equivalent and is the recommended substitute.

Q: What is the key difference between HM2P82PKA1M1GFLF and 5646457-1? A: The primary difference is position count and row configuration. HM2P82PKA1M1GFLF maintains 110 positions in 8 + 2 rows, while 5646457-1 provides 88 positions in 8 rows. Both share the same 0.079" pitch, press-fit termination, and electrical specifications. The 5646457-1 is suitable only for applications requiring 88 or fewer positions.

Q: Are there packaging differences between these substitutes? A: Yes. HM2P82PKA1M1GF is supplied without specified packaging, HM2P82PKA1M1GFLF is supplied in trays, and 5646457-1 is supplied in tubes. Packaging does not affect electrical or mechanical compatibility.

Q: Do all three parts meet RoHS compliance requirements? A: No. HM2P82PKA1M1GF is RoHS non-compliant. Both HM2P82PKA1M1GFLF and 5646457-1 are RoHS compliant. For applications requiring RoHS compliance, either active substitute is acceptable.

Q: What is the significance of contact finish thickness differences? A: HM2P82PKA1M1GF and 5646457-1 specify 30.0µin (0.76µm) gold contact finish thickness, while HM2P82PKA1M1GFLF specifies flash thickness. Both finishes provide gold contact surfaces suitable for the specified electrical and environmental parameters. Flash thickness represents a thinner gold layer applied to the base metal.
