Parameter Comparison

Engineering Selection Recommendations

The substitute part 2-644486-2 is the direct functional equivalent of the obsolete 644486-2. Both components share identical electrical ratings, mechanical dimensions, and performance specifications across all critical parameters.

Product Status Consideration: The main part 644486-2 carries obsolete status, indicating discontinued manufacturing and limited availability. The substitute 2-644486-2 maintains active product status with significantly higher inventory levels (12,538 pieces versus 703 pieces), ensuring reliable supply chain continuity.

Regulatory Compliance Enhancement: The substitute part 2-644486-2 provides improved regulatory positioning through ROHS3 compliance and REACH unaffected status, compared to the non-compliant and vendor-undefined status of the original part. This compliance upgrade aligns with current environmental and safety standards without requiring design modifications.

Contact Finish Specification: The substitute part transitions from Tin-Lead contact finish to Tin contact finish on both mating and post surfaces. This change reflects industry-wide lead-free initiatives and maintains electrical and mechanical performance equivalence for general-purpose applications.

Direct Substitution Capability: The 2-644486-2 connector header operates identically to the 644486-2 in all board-to-cable/wire connection scenarios. Through-hole mounting, solder termination, friction lock fastening, and all dimensional specifications remain unchanged, enabling direct substitution without circuit board redesign or application modification.

Frequently Asked Questions (FAQ)

Q: Can the 2-644486-2 be used as a direct replacement for the 644486-2 in existing designs?

A: Yes. The 2-644486-2 is a direct functional equivalent with identical electrical ratings (250VAC), mechanical dimensions, pitch (0.100"/2.54mm), position count (2), mounting type (through-hole), and operating temperature range (-55°C to 105°C). No design modifications are required.

Q: What is the difference between Tin-Lead and Tin contact finishes?

A: Both finishes provide equivalent electrical conductivity and mechanical performance for general-purpose connector applications. Tin contact finish represents a lead-free alternative that complies with current environmental regulations. The substitute part's Tin finish maintains the same contact resistance and mating characteristics as the original Tin-Lead finish.

Q: Why does the substitute part have higher inventory availability?

A: The 2-644486-2 maintains active product status with 12,538 pieces in stock, compared to 703 pieces for the obsolete 644486-2. Active status indicates ongoing manufacturing and distribution, ensuring consistent availability for production requirements.

Q: Are there packaging differences between the main part and substitute?

A: The main part 644486-2 packaging is unspecified in the provided data. The substitute part 2-644486-2 is supplied in bulk packaging. Packaging format does not affect electrical or mechanical performance and can be managed through standard component handling procedures.

Q: Does the ROHS3 compliance of the substitute part affect compatibility?

A: No. ROHS3 compliance indicates adherence to environmental standards and does not alter electrical or mechanical specifications. The substitute part maintains identical performance characteristics while meeting enhanced regulatory requirements.

Q: What is the significance of the REACH unaffected status?

A: REACH unaffected status indicates the substitute part does not contain substances of very high concern (SVHC) requiring special handling or documentation. This represents improved regulatory positioning compared to the vendor-undefined status of the original part, with no impact on functional performance.

Q: Can the 644486-2 and 2-644486-2 be used interchangeably in the same application?

A: Yes. Both parts are electrically and mechanically equivalent across all critical parameters. The substitute part provides the added benefit of active product status and enhanced regulatory compliance, making it the preferred choice for new production and ongoing applications.
