Substitute Part Grouping Explanation

The M22-2035005 is identified as a manufacturer-recommended substitute for the M22-2532205. Both connectors share the following critical parameters that establish substitution eligibility:

Same manufacturer (Harwin Inc.) and series (M22)
Identical pitch specification (0.079" / 2.00mm)
Identical connector type (Header, Cuttable)
Identical mounting type (Through Hole, Right Angle)
Identical contact type (Male Pin)
Identical contact material (Phosphor Bronze)
Identical contact finish (Gold)
Identical insulation material (Polyamide PA6T, Nylon 6T)
Identical current rating (1A per Contact)
Identical flammability rating (UL94 V-0)
Identical RoHS and REACH compliance status

The primary difference is the number of positions: the substitute provides 50 positions versus the original 22 positions. The M22-2035005 is an active product with current manufacturing support, addressing the obsolescence status of the original part.

Engineering Selection Recommendations

The M22-2035005 is the manufacturer-recommended substitute for the obsolete M22-2532205. Both connectors maintain identical electrical and mechanical specifications across all critical parameters, including pitch, contact material, current rating, and operating temperature range. The substitute offers an extended lower operating temperature limit (-55°C versus -40°C), providing enhanced thermal performance.

The primary design consideration is the increased number of positions (50 versus 22). The M22-2035005 is a cuttable header, allowing users to configure the connector to the required 22-position specification through mechanical separation. This approach maintains full electrical and mechanical compatibility while providing access to an active product with current manufacturing support and inventory availability.

Both parts maintain identical RoHS3 and REACH compliance status, ensuring regulatory continuity in applications requiring these certifications.

Frequently Asked Questions (FAQ)

Q: Can the M22-2035005 be used as a direct replacement for the M22-2532205?

A: Yes. Both connectors share identical pitch (2.00mm), contact type, material composition, and electrical ratings. The M22-2035005 is a cuttable header available in 50 positions, which can be configured to 22 positions through mechanical separation.

Q: What is the significance of the "cuttable" designation?

A: The cuttable feature allows the connector to be mechanically divided to the required number of positions. For the M22-2035005, this enables configuration from the standard 50-position offering down to 22 positions, matching the original part's functionality.

Q: Are there differences in contact post length between these connectors?

A: Yes. The M22-2532205 has a contact post length of 0.094" (2.40mm), while the M22-2035005 has 0.118" (3.00mm). This difference does not affect compatibility, as both maintain the same mating contact length (0.138" / 4.60mm) and insulation height (0.079" / 2.00mm).

Q: Does the M22-2035005 offer improved temperature performance?

A: The M22-2035005 extends the lower operating temperature limit to -55°C compared to -40°C for the M22-2532205, providing a wider operating range while maintaining the same upper limit of 105°C.

Q: Are both connectors RoHS and REACH compliant?

A: Yes. Both the M22-2532205 and M22-2035005 are ROHS3 compliant and REACH unaffected, maintaining identical regulatory status.

Q: What is the current availability status of these parts?

A: The M22-2532205 is obsolete. The M22-2035005 is an active product with current manufacturing support and documented inventory availability.
