TE Connectivity 66682-6 Equivalent & Substitute Parts

Part Overview

The TE Connectivity 66682-6 is a pin contact for the AMPLIMITE HDP-20 connector series, designed for 24-28 AWG wire gauges with gold-plated brass construction and crimp termination. This component is classified as obsolete, necessitating identification of active equivalent parts for ongoing procurement and system maintenance. Substitute parts must maintain identical electrical and mechanical specifications to ensure proper connector assembly and performance.

Substitute Part Grouping Explanation

Substitution of the obsolete 66682-6 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

Series designation (AMPLIMITE HDP-20)
Contact type (Stamped pin)
Termination method (Crimp)
Wire gauge range (24-28 AWG)
Contact material (Brass)
Contact finish (Gold)
Moisture sensitivity level (MSL 1)

Substitute Classification:

Direct Equivalent: Part 5066682-6 maintains all mandatory parameters and represents the current active production equivalent with identical electrical and mechanical characteristics.

Similar Equivalent: Part 66682-2 maintains all mandatory parameters with a documented difference in contact finish thickness specification (30.0µin / 0.76µm versus flash thickness on the original part).

Both substitute parts are active products with current manufacturing status, addressing the obsolescence of the original 66682-6.

Engineering Selection Recommendations

Primary Substitute: 5066682-6

Part 5066682-6 is the recommended direct equivalent for replacement of the obsolete 66682-6. This part maintains identical electrical and mechanical specifications while offering the following advantages:

Active product status with continuous manufacturing availability
RoHS Compliant certification
REACH Unaffected regulatory status
Standardized Cut Tape packaging for automated assembly processes
Higher inventory availability (27,359 units in stock)

Secondary Substitute: 66682-2

Part 66682-2 functions as a compatible alternative with the following considerations:

Active product status with established supply chain
RoHS Compliant certification
Specified contact finish thickness of 30.0µin (0.76µm) versus flash thickness on the original part
REACH status listed as Vendor Undefined
Adequate inventory availability (22,583 units in stock)

Both substitute parts satisfy the mandatory electrical and mechanical requirements for AMPLIMITE HDP-20 series connector assembly. Selection between 5066682-6 and 66682-2 depends on specific regulatory compliance requirements and contact finish thickness specifications for the end application.

Frequently Asked Questions (FAQ)

Q: Can 5066682-6 be used as a direct replacement for 66682-6?

A: Yes. Part 5066682-6 maintains all critical electrical and mechanical parameters including wire gauge, contact material, finish type, and termination method. The parts are functionally equivalent for AMPLIMITE HDP-20 connector assembly.

Q: What is the difference between 5066682-6 and 66682-2?

A: Both parts are compatible substitutes with identical wire gauge, termination, and material specifications. The primary difference is contact finish thickness: 5066682-6 specifies flash thickness while 66682-2 specifies 30.0µin (0.76µm). This difference may affect contact resistance characteristics in specific applications.

Q: Why is the original 66682-6 listed as obsolete?

A: The 66682-6 has been discontinued by TE Connectivity. Active equivalent parts 5066682-6 and 66682-2 are available for new designs and replacement applications.

Q: Are the substitute parts RoHS compliant?

A: Yes. Both 5066682-6 and 66682-2 are RoHS Compliant, addressing environmental and regulatory requirements that the original 66682-6 does not meet.

Q: What packaging formats are available for the substitute parts?

A: Both substitute parts are supplied in Cut Tape (CT) packaging, suitable for automated pick-and-place assembly operations.

Q: Do the substitute parts have the same wire gauge compatibility?

A: Yes. All parts including the original 66682-6 and both substitutes support 24-28 AWG wire gauges with crimp termination.

Q: What is the Moisture Sensitivity Level for these parts?

A: All three parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions for storage or handling.
