Key Parameters

Substitute Part Grouping Explanation

The M22-2520746 qualifies as a direct substitute based on the following critical parameters:

• Pitch Specification: Both parts maintain 0.079" (2.00mm) mating pitch
• Position Count: Both feature 14 positions in a 2-row configuration
• Row Spacing: Identical 0.079" (2.00mm) row spacing ensures mechanical compatibility
• Connector Family: Both belong to the M22 series from Harwin Inc.
• Compliance Standards: Both are ROHS3 compliant with MSL 1 rating
• Regulatory Classification: Both carry identical ECCN (EAR99) and HTSUS (8536.69.4040) codes

The primary distinction is product status: M22-2520746 is Active, providing supply continuity for applications currently using the Obsolete M22-2720746.

Parameter Comparison

Frequently Asked Questions (FAQ)

Q: Can M22-2520746 be used as a direct replacement for M22-2720746 in existing designs?

A: Yes. Both parts share identical mating pitch (0.079" / 2.00mm), position count (14), row configuration (2 rows), and row spacing. Mechanical and electrical compatibility is established through these matching parameters.

Q: What is the primary reason for substitution?

A: M22-2720746 is classified as Obsolete. M22-2520746 provides functional equivalence with Active product status, ensuring continued availability for procurement and support.

Q: Are there compliance differences between the two parts?

A: No. Both parts are ROHS3 compliant, REACH Unaffected, carry identical ECCN (EAR99) and HTSUS (8536.69.4040) classifications, and share MSL 1 (Unlimited) moisture sensitivity ratings.

Q: What additional specifications does M22-2520746 provide?

A: M22-2520746 includes documented electrical and thermal parameters: Through Hole mounting, Solder termination, 1A per contact current rating, and -40°C to 105°C operating temperature range. These specifications support design verification but do not affect substitution compatibility.

Q: Is the cuttable feature of M22-2520746 a compatibility concern?

A: No. The cuttable feature is an additional capability that does not affect interchangeability. Applications requiring fixed 14-position headers can utilize M22-2520746 without modification.
