TE Connectivity 644487-4 Equivalent & Substitute Parts

Part Overview

The TE Connectivity 644487-4 is a rectangular connector header designed for through-hole mounting applications. This shrouded 4-position connector operates at 250VAC with a 0.100" (2.54mm) pitch and is part of the MTA-100 series. The connector features male pins with gold-plated mating contacts and tin-lead plated posts for solder termination. The product maintains Active status and is RoHS3 compliant with UL94 V-0 flammability rating. Substitute parts are identified when electrical specifications, mechanical dimensions, and connector interface parameters remain equivalent across manufacturing variants.

Key Parameters

Substitute Part Grouping Explanation

Substitution of rectangular connector headers is determined by equivalence across the following critical parameters: connector type classification, contact gender and pin configuration, position count, mating pitch dimension, mounting methodology, shrouding design, voltage and temperature ratings, and contact finish specifications on mating surfaces. The substitute part 2-644487-4 maintains identical specifications across all these parameters with the exception of the post contact finish material. The main part 644487-4 specifies tin-lead plating on posts, while the substitute part 2-644487-4 specifies tin plating on posts. Both finishes are compatible with solder termination processes and do not affect the mating interface or electrical performance of the connector header assembly.

Parameter Comparison

Engineering Selection Recommendations

Both the 644487-4 and 2-644487-4 maintain Active product status and full RoHS3 compliance. The connector headers are functionally equivalent for through-hole board-to-cable applications requiring 4-position, 0.100" pitch rectangular connectors with 250VAC rating and -55°C to 105°C operating range. The primary distinction between these parts is the post contact finish specification: tin-lead versus tin. Both finishes are suitable for solder termination and do not impact mating interface performance or electrical characteristics. Selection between these parts is based on post-plating material preference and availability. The substitute part 2-644487-4 currently maintains higher inventory availability at 9579 pieces compared to 1023 pieces for the main part 644487-4.

Frequently Asked Questions (FAQ)

Q: What determines if a connector header can substitute for the 644487-4?

A: Substitution is determined by equivalence in connector type, contact gender, position count, mating pitch, mounting method, shrouding configuration, voltage and temperature ratings, and mating contact finish. The 2-644487-4 meets all these criteria.

Q: What is the difference between the 644487-4 and 2-644487-4?

A: The primary difference is the post contact finish material. The 644487-4 features tin-lead plating on posts, while the 2-644487-4 features tin plating on posts. Both are compatible with solder termination processes.

Q: Are the mating dimensions identical between these parts?

A: Yes. Both parts share identical mating pitch (0.100"), contact length (0.200"), insulation height (0.410"), and overall contact length (0.440"). The connectors are mechanically and electrically interchangeable at the mating interface.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the 644487-4 and 2-644487-4 are RoHS3 compliant, UL94 V-0 rated, and classified under the same ECCN (EAR99) and HTSUS codes.

Q: What is the operating temperature range for these connectors?

A: Both parts operate across -55°C to 105°C, suitable for industrial and general-purpose applications.

Q: Can these connectors be used interchangeably in existing designs?

A: Yes. The 644487-4 and 2-644487-4 are direct substitutes with identical electrical and mechanical specifications for mating interfaces. Post finish material differences do not affect connector performance or compatibility.

Q: What is the voltage rating for these connector headers?

A: Both parts are rated for 250VAC operation.

Q: Are these connectors suitable for high-reliability applications?

A: These connectors are classified for general-purpose applications. The UL94 V-0 flammability rating and RoHS3 compliance support use in standard industrial and commercial environments.
