Key Parameters

Substitute Part Grouping Explanation

Substitution of the 1-644486-4 is determined by strict equivalence across the following critical parameters:

Electrical Parameters: Voltage rating of 250VAC and operating temperature range of -55°C to 105°C must be maintained.

Mechanical Parameters: 14-position, single-row configuration with 0.100" (2.54mm) pitch mating spacing, male pin contact type, through-hole mounting, and shrouded 4-wall design are non-negotiable for physical and functional compatibility.

Contact and Termination: Solder termination with square contact shape and copper alloy material must be preserved.

Compliance and Safety: UL94 V-0 flammability rating and material composition must be equivalent.

The substitute part 3-644486-4 meets all these criteria while offering improved product status and compliance characteristics.

Parameter Comparison

Engineering Selection Recommendations

The 3-644486-4 serves as the direct substitute for the obsolete 1-644486-4. Both connectors maintain identical electrical and mechanical specifications across all critical parameters including pitch, position count, voltage rating, temperature range, and physical dimensions.

The primary distinction between these parts is product status and regulatory compliance. The 1-644486-4 is classified as obsolete and carries RoHS non-compliant status with vendor-undefined REACH compliance. The 3-644486-4 is an active product with RoHS compliance and REACH unaffected status, making it suitable for new designs and applications subject to modern regulatory requirements.

The contact finish differs between the two parts: the 1-644486-4 features tin-lead plating while the 3-644486-4 uses tin plating. This change reflects the transition away from lead-based finishes in modern connector manufacturing. Both finishes are compatible with standard solder assembly processes and provide equivalent electrical performance for the specified application.

For applications requiring the exact tin-lead finish specification of the original part, the 1-644486-4 remains available in current inventory. For new designs and applications requiring RoHS compliance, the 3-644486-4 is the appropriate selection.

Frequently Asked Questions (FAQ)

Q: Are the 1-644486-4 and 3-644486-4 physically interchangeable?

A: Yes. Both connectors share identical mechanical dimensions, mounting type, pitch spacing, and position count. They are direct physical substitutes for each other in through-hole applications.

Q: What is the difference in contact finish between these parts?

A: The 1-644486-4 uses tin-lead plating on both mating and post contacts. The 3-644486-4 uses tin plating. Both finishes are compatible with standard solder assembly and provide equivalent electrical performance for the 250VAC, 14-position application.

Q: Why is the 1-644486-4 listed as obsolete?

A: The 1-644486-4 has been superseded by the 3-644486-4, which offers improved regulatory compliance including RoHS certification and REACH unaffected status. The obsolete designation indicates that TE Connectivity no longer actively manufactures this variant.

Q: Can I use the 3-644486-4 in place of the 1-644486-4 in existing designs?

A: Yes. The 3-644486-4 is electrically and mechanically equivalent to the 1-644486-4 and functions identically in all specified applications. The change in contact finish from tin-lead to tin does not affect performance in standard solder assembly processes.

Q: What is the packaging difference between these parts?

A: The 1-644486-4 packaging specification is not provided. The 3-644486-4 is supplied in bulk packaging. Confirm packaging requirements with your procurement specifications.

Q: Are both parts suitable for -55°C to 105°C operating temperature applications?

A: Yes. Both the 1-644486-4 and 3-644486-4 are rated for the identical operating temperature range of -55°C to 105°C and maintain UL94 V-0 flammability rating across this range.

Q: Which part should I specify for new designs?

A: The 3-644486-4 is the appropriate selection for new designs. It offers active product status, RoHS compliance, and REACH unaffected designation, ensuring compatibility with current regulatory requirements and long-term availability.
