Key Parameters

Substitute Part Grouping Explanation

Substitution between the TE Connectivity 640583-2 and 640583-3 is based on electrical and mechanical parameter equivalence within the Universal MATE-N-LOK series. Both parts share identical specifications across all critical connector characteristics: 6-position configuration, 0.250" (6.35mm) mating pitch, through-hole right-angle mounting, shrouded 4-wall design, solder termination, and locking ramp fastening. Electrical ratings remain constant at 12A current capacity and 600VAC voltage rating. Thermal performance, contact materials (phosphor bronze), contact finishes (gold mating surface, tin post), and insulation properties (polyamide nylon, white color) are identical between both parts.

The primary distinction between these parts is packaging format and RoHS compliance status. The 640583-2 is supplied in standard packaging with RoHS non-compliant status, while the 640583-3 is supplied in bulk packaging with RoHS compliant status. Both parts maintain active product status and identical mechanical and electrical performance characteristics that determine functional interchangeability.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity 640583-3 serves as a direct functional equivalent to the 640583-2 for applications requiring identical electrical and mechanical performance. Both parts maintain active product status and deliver equivalent connector functionality across all specified parameters.

Selection between these parts should be based on compliance and packaging requirements. The 640583-3 is the appropriate choice for applications subject to RoHS compliance mandates, as it carries RoHS compliant certification. The 640583-2 remains suitable for applications without RoHS compliance requirements. Packaging format differs between the two parts: the 640583-2 is supplied in standard packaging, while the 640583-3 is supplied in bulk packaging. Bulk packaging may be advantageous for high-volume production environments or applications requiring large quantity procurement.

Both parts carry identical UL94 V-0 flammability ratings, moisture sensitivity level 1 (unlimited), and export classification (EAR99), ensuring equivalent performance in thermal, environmental, and regulatory contexts.

Frequently Asked Questions (FAQ)

Q: Are the 640583-2 and 640583-3 electrically interchangeable?
