Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 640252-1 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Series designation (SL-156)
• Contact type (Socket)
• Termination method (Crimp)
• Wire gauge range (18-24 AWG)
• Contact finish thickness (80.0µin / 2.03µm)
• Moisture sensitivity level (MSL 1)
• Connector category (Rectangular Connectors)
• Application type (Power)

The substitute part 3-640252-1 maintains full equivalence across all mandatory parameters. The primary distinction between the main part and its substitute is the contact finish composition and product status. The main part features tin-lead finish and is obsolete, while the substitute features tin finish and maintains active product status. Both components share identical wire gauge capacity, termination methodology, and physical specifications.

Parameter Comparison

Engineering Selection Recommendations

For New Designs and Procurement:

The substitute part 3-640252-1 is the appropriate selection for all applications currently specified for 640252-1. This substitute maintains complete functional equivalence while offering significant advantages in product lifecycle status and regulatory compliance.

The 3-640252-1 is an active product with current manufacturing support and availability, eliminating supply chain constraints associated with obsolete components. The substitute achieves ROHS3 compliance, whereas the original part is non-compliant. Both components share identical electrical and mechanical specifications, including wire gauge capacity, termination method, contact finish thickness, and moisture sensitivity rating.

The contact finish difference (tin versus tin-lead) does not affect functional compatibility within the SL-156 series application envelope. Both finishes provide equivalent contact resistance and durability characteristics at the specified finish thickness of 80.0µin (2.03µm).

For Legacy System Maintenance:

When servicing existing systems originally specified with 640252-1, the 3-640252-1 substitute provides direct functional replacement without design modification or system recertification requirements.

Frequently Asked Questions (FAQ)

Q: Can 3-640252-1 directly replace 640252-1 in existing assemblies?

A: Yes. The 3-640252-1 maintains complete functional equivalence across all critical parameters: series designation, socket type, crimp termination, 18-24 AWG wire gauge capacity, contact finish thickness, and moisture sensitivity rating. Direct substitution is supported without assembly modification.

Q: What is the significance of the contact finish difference between tin-lead and tin?

A: Both finishes are applied at identical thickness (80.0µin / 2.03µm) and provide equivalent contact performance within the SL-156 series specifications. The tin finish in the substitute part reflects current manufacturing standards and regulatory compliance requirements.

Q: Why is the original 640252-1 listed as obsolete?

A: Product obsolescence reflects manufacturer lifecycle decisions. The active substitute 3-640252-1 provides continued access to equivalent functionality with current manufacturing support and improved compliance status.

Q: Does the ROHS3 compliance of 3-640252-1 affect compatibility with systems designed for 640252-1?

A: No. ROHS3 compliance is a manufacturing and environmental standard that does not alter electrical or mechanical performance. The substitute part operates identically to the original within all specified parameters.

Q: What packaging format is available for the substitute part?

A: The 3-640252-1 is supplied in Cut Tape (CT) packaging format. Inventory availability is 71,623 pieces in new original condition.

Q: Are there any wire gauge or termination differences between these parts?

A: No. Both parts support identical 18-24 AWG wire gauge range and utilize crimp termination methodology. Connector performance and installation procedures remain unchanged.
