Key Parameters

Substitute Part Grouping Explanation

The M22-2530805 qualifies as a direct substitute based on the following critical parameters:

• Pitch Compatibility: Both parts maintain 0.079" (2.00mm) mating pitch, ensuring mechanical and electrical interchangeability
• Position Count: Both feature 8-position configuration for identical contact density
• Row Configuration: Single-row layout matches across both parts
• Compliance Alignment: Both parts are ROHS3 Compliant, REACH Unaffected, and share identical MSL rating of 1 (Unlimited)
• Manufacturer Consistency: Both manufactured by Harwin Inc., ensuring design continuity and supply chain reliability
• Contact Specifications: Identical contact material (Phosphor Bronze), contact finish (Gold mating surface), and current rating (1A per contact)
• Insulation Material: Both utilize Polyamide (PA6T), Nylon 6T insulation
• Operating Temperature Range: Both rated -40°C ~ 105°C
• Flammability Rating: Both meet UL94 V-0 standard

The primary distinction is mounting configuration: M22-2730846 uses standard through-hole mounting, while M22-2530805 employs right-angle through-hole mounting. This difference affects PCB layout integration but does not impact electrical performance or contact compatibility.

Parameter Comparison

Engineering Selection Recommendations

The M22-2530805 is the designated substitute for the obsolete M22-2730846. Selection criteria are based on:

• Product Status: M22-2530805 maintains Active status, ensuring long-term availability and supply chain continuity
• Regulatory Compliance: Both parts maintain identical ROHS3 and REACH certifications, satisfying regulatory requirements without modification
• Electrical Equivalence: Identical contact specifications, current ratings, and operating temperature ranges ensure electrical performance parity
• Mechanical Compatibility: Matching pitch, position count, and row configuration provide mechanical interchangeability at the contact interface
• Manufacturing Consistency: Single-manufacturer sourcing from Harwin Inc. maintains design integrity and quality standards

The right-angle mounting configuration of M22-2530805 requires PCB layout adjustment compared to the straight-through-hole mounting of M22-2730846. This is a mechanical consideration only and does not affect electrical functionality or contact performance.

Frequently Asked Questions (FAQ)

Q: Can M22-2530805 directly replace M22-2730846 without PCB redesign?

A: Electrical and contact compatibility is direct. However, the right-angle mounting of M22-2530805 versus straight mounting of M22-2730846 requires PCB footprint modification. Hole placement and orientation must be adjusted accordingly.

Q: Are the contact specifications identical between these parts?

A: Yes. Both parts feature identical male pin contacts, Phosphor Bronze material, gold mating finish, and 1A per contact current rating. Contact length specifications differ but do not affect interchangeability at the mating interface.

Q: Do compliance certifications remain unchanged with substitution?

A: Yes. Both parts maintain ROHS3 Compliance, REACH Unaffected status, and identical Moisture Sensitivity Level 1 rating. No compliance modifications are required.

Q: What is the primary reason for substitution?

A: M22-2730846 is classified as Obsolete. M22-2530805 is the active equivalent, ensuring continued availability and supply chain reliability.

Q: Are there differences in insulation or material specifications?

A: No. Both parts use identical Polyamide (PA6T), Nylon 6T insulation material and share the same UL94 V-0 flammability rating.

Q: What operating conditions are supported by the substitute part?

A: M22-2530805 operates across the identical temperature range of -40°C to 105°C, matching the original part specifications.
