HM2K31P16 Equivalent & Substitute Parts

Part Overview

The HM2K31P16 is a 55-position shroud for male pins connector manufactured by Amphenol ICC (FCI) in the Millipacs® series. This through-hole hard metric Type C backplane connector is designed for header applications with a 0.079" (2.00mm) pitch and 5 + 2 row configuration. The part is currently obsolete, making identification of suitable alternatives essential for ongoing system support and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the HM2K31P16 is determined by the following critical parameters:

• Base Product Number: Both the main part and substitute share the HM2K31 base designation, indicating they belong to the same connector family
• Manufacturer: Both are manufactured by Amphenol ICC (FCI), ensuring design and quality consistency
• Category: Both are classified as backplane connectors
• ECCN and HTSUS Classification: Identical export control and tariff classifications confirm functional equivalence within regulatory frameworks

The substitute part HM2K31P16LF maintains the same base product number and manufacturer, establishing direct compatibility within the Amphenol ICC connector ecosystem.

Parameter Comparison

Engineering Selection Recommendations

The HM2K31P16LF is the direct substitute for the obsolete HM2K31P16. Both parts share the same base product number (HM2K31) and manufacturer (Amphenol ICC/FCI), confirming functional equivalence. The substitute part is currently in active production status with 1104 units available in inventory.

A key distinction is the RoHS compliance status: the HM2K31P16LF is RoHS compliant, while the original part is RoHS non-compliant. This compliance upgrade is significant for applications subject to RoHS regulations. Both parts maintain identical MSL ratings and export classifications, ensuring no change in handling, storage, or regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can HM2K31P16LF directly replace HM2K31P16 in existing designs?

A: Yes. Both parts share the HM2K31 base product number and are manufactured by Amphenol ICC (FCI). The shared base designation and manufacturer confirm direct compatibility.

Q: What is the significance of the "LF" suffix in HM2K31P16LF?

A: The "LF" designation indicates lead-free construction and RoHS compliance. This represents a material composition upgrade from the original part while maintaining the same connector family specifications.

Q: Are there any differences in electrical or mechanical specifications between these parts?

A: The provided data confirms both parts share identical ECCN and HTSUS classifications. Detailed electrical and mechanical specifications beyond those listed are not provided in the available documentation.

Q: What is the inventory status for these parts?

A: The original HM2K31P16 has 624 units in stock (obsolete status). The substitute HM2K31P16LF has 1104 units available (active production status).

Q: Does the RoHS compliance change affect compatibility?

A: RoHS compliance reflects material composition changes (lead-free solder, compliant materials) but does not affect mechanical or electrical compatibility. The change is beneficial for applications requiring regulatory compliance.
