Key Parameters

Substitute Part Grouping Explanation

The M22-2530405 qualifies as a direct substitute based on the following critical parameters:

• Manufacturer: Both parts are manufactured by Harwin Inc., ensuring design consistency and quality standards
• Pitch - Mating: Both parts maintain 0.079" (2.00mm) pitch, enabling mechanical and electrical compatibility
• Number of Positions: Both parts provide 4 positions in a single row configuration
• Category: Both are rectangular connectors within the same product family
• Compliance: Both maintain ROHS3 compliance, REACH Unaffected status, and identical MSL rating (1)
• Regulatory Classification: Both share identical ECCN (EAR99) and HTSUS codes

The primary distinction is that M22-2530405 is an active product with right-angle through-hole mounting, whereas M22-2730405 is obsolete. The substitute part provides continued access to functionally equivalent connector technology.

Parameter Comparison

Engineering Selection Recommendations

The M22-2530405 is the designated substitute for the obsolete M22-2730405. Selection of this substitute is supported by:

• Active Product Status: M22-2530405 maintains active manufacturing status, ensuring long-term availability and supply chain continuity
• Regulatory Compliance: Both parts maintain identical ROHS3 compliance and REACH Unaffected status, satisfying environmental and regulatory requirements
• Electrical and Mechanical Compatibility: Matching pitch (2.00mm), position count (4), contact material, and current rating (1A per contact) ensure functional equivalence
• Thermal Performance: Identical operating temperature range (-40°C to 105°C) and material flammability rating (UL94 V-0) maintain thermal and safety specifications
• Manufacturing Consistency: Both parts originate from Harwin Inc., ensuring design lineage and quality standards

The primary design consideration is the mounting orientation difference: M22-2530405 features right-angle through-hole mounting compared to the straight-through configuration of M22-2730405. PCB layout modifications may be required to accommodate this orientation change.

Frequently Asked Questions (FAQ)

Q: Can M22-2530405 directly replace M22-2730405 without PCB redesign?

A: Electrical and mechanical compatibility is confirmed through matching pitch, position count, contact material, and current rating. However, the right-angle mounting orientation of M22-2530405 differs from M22-2730405. PCB footprint and layout modifications are necessary to accommodate this mounting difference.

Q: Are the compliance certifications identical between these parts?

A: Yes. Both parts maintain ROHS3 compliance, REACH Unaffected status, identical MSL rating (1), and matching ECCN (EAR99) and HTSUS codes (8536.69.4040).

Q: What is the operational temperature range for both parts?

A: Both M22-2730405 and M22-2530405 operate within -40°C to 105°C, with identical material flammability rating (UL94 V-0).

Q: Why is M22-2730405 listed as obsolete?

A: M22-2730405 has been discontinued by Harwin Inc. The M22-2530405 represents the active product line continuation within the M22 series, providing equivalent functionality with right-angle mounting configuration.

Q: Are there packaging differences between these parts?

A: M22-2730405 packaging information is not specified in available documentation. M22-2530405 is supplied in bulk packaging. Confirm packaging requirements with your procurement specifications.

Q: What is the current rating per contact?

A: Both parts are rated at 1A per contact, supporting identical electrical load specifications.
