HM2H29P16 Equivalent & Substitute Parts

Part Overview

The HM2H29P16 is a 125-position shroud for male pins connector manufactured by Amphenol ICC (FCI) in the Millipacs® series. This through-hole hard metric Type B 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 eligibility for the HM2H29P16 is determined by the following critical parameters:

• Base product number alignment (HM2H29 family)
• Manufacturer continuity (Amphenol ICC / FCI)
• Connector category classification (Backplane Connectors)
• Export classification consistency (ECCN EAR99)
• Tariff code alignment (HTSUS 8538.90.8180)
• Moisture sensitivity rating (MSL 1)

The HM2H29P16LF qualifies as a direct substitute based on shared base product number, manufacturer, category, export classification, tariff code, and moisture sensitivity level. This part represents an active product variant within the same connector family.

Parameter Comparison

Engineering Selection Recommendations

The HM2H29P16LF is the active production equivalent for the obsolete HM2H29P16. Selection between these parts should be based on the following criteria:

For new designs or long-term procurement: The HM2H29P16LF is the appropriate choice. This part maintains the same base product number and connector family classification while offering active product status and RoHS compliance. Both parts share identical export classification, tariff coding, and moisture sensitivity ratings.

For legacy system support: The HM2H29P16 remains available in inventory (848 units) for applications requiring the original non-compliant specification. The HM2H29P16LF provides a compliant alternative with higher inventory availability (1135 units).

Compliance considerations: Organizations subject to RoHS regulations should transition to HM2H29P16LF. Both parts maintain equivalent export and tariff classifications under EAR99 and HTSUS 8538.90.8180.

Frequently Asked Questions (FAQ)

Q: Can HM2H29P16LF directly replace HM2H29P16 in existing applications?

A: Both parts share the same base product number (HM2H29) and belong to the Amphenol ICC Millipacs® backplane connector family. The HM2H29P16LF represents the active production variant. Compatibility depends on application-specific requirements not detailed in the base specifications. Electrical and mechanical parameters not provided in the specification should be verified against application requirements.

Q: What is the significance of the "LF" suffix in HM2H29P16LF?

A: The "LF" designation indicates RoHS compliance in the Amphenol ICC naming convention. This represents the primary difference between the obsolete HM2H29P16 and the active HM2H29P16LF variant.

Q: Are there inventory implications for selecting between these parts?

A: The HM2H29P16LF has higher inventory availability (1135 units) compared to the HM2H29P16 (848 units). For procurement planning, the active HM2H29P16LF offers better long-term supply assurance.

Q: Do both parts share the same export and tariff classifications?

A: Yes. Both the HM2H29P16 and HM2H29P16LF are classified under ECCN EAR99 and HTSUS code 8538.90.8180, indicating identical export control and tariff treatment.

Q: What is the moisture sensitivity rating for these connectors?

A: Both parts carry an MSL rating of 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.
