TE Connectivity AMP Connectors 66461-3 Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 66461-3 is a socket contact designed for wire wrap termination applications within the Multimate III+ connector series. This stamped brass contact features tin-lead plating and is classified as obsolete product status. Due to its obsolete designation and non-RoHS compliance, identification of active equivalent parts is necessary for ongoing procurement and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 66461-3 is based on strict equivalence across the following parameters:

• Series Compatibility: Both parts belong to the Multimate III+ connector series
• Contact Configuration: Socket contact type maintained
• Termination Method: Wire wrap termination preserved
• Base Material: Brass contact material consistent
• Finish Thickness: Contact finish thickness of 100.0µin (2.54µm) identical
• Moisture Sensitivity: MSL rating of 1 (Unlimited) maintained
• Manufacturing Process: Stamped contact type consistent

The primary distinction between the main part and its substitute relates to contact finish composition and product status compliance.

Engineering Selection Recommendations

The 5-66461-9 serves as the direct substitute for the 66461-3 based on the following engineering criteria:

Product Status Alignment: The 5-66461-9 maintains active product status, ensuring continued availability and manufacturer support, whereas the 66461-3 is classified as obsolete.

Regulatory Compliance: The 5-66461-9 achieves RoHS compliance, meeting current environmental and regulatory requirements for electronic component procurement. The 66461-3 does not meet RoHS standards.

Functional Equivalence: Both contacts maintain identical wire wrap termination capability, brass base material, and finish thickness specifications, ensuring mechanical and electrical compatibility within Multimate III+ connector assemblies.

Contact Finish Consideration: The 5-66461-9 utilizes tin plating in place of tin-lead plating. This change reflects industry-wide transition to lead-free materials and does not compromise contact performance or reliability within the specified application parameters.

Frequently Asked Questions (FAQ)

Q: Can the 5-66461-9 be used as a direct replacement for the 66461-3 in existing Multimate III+ assemblies?

A: Yes. Both contacts share identical series designation, socket configuration, wire wrap termination method, brass material composition, and finish thickness specifications. The contacts are mechanically and electrically compatible within the Multimate III+ connector system.

Q: What is the difference between tin-lead and tin contact finishes?

A: The 66461-3 features tin-lead plating, while the 5-66461-9 features tin plating. Both finishes provide equivalent contact resistance and reliability performance at the specified 100.0µin (2.54µm) thickness. The tin finish reflects industry adoption of lead-free materials.

Q: Why is the 66461-3 classified as obsolete?

A: The 66461-3 is designated obsolete due to its non-RoHS compliance status and the availability of the active equivalent 5-66461-9. Manufacturers discontinue non-compliant products in favor of RoHS-compliant alternatives.

Q: Are there inventory considerations when selecting between these parts?

A: The 66461-3 has 1965 pieces in stock as new original inventory. The 5-66461-9 has 12426 pieces in stock. For new designs and ongoing procurement, the 5-66461-9 is the recommended selection due to active product status and higher inventory availability.

Q: Do both contacts share the same base product number?

A: Yes. Both the 66461-3 and 5-66461-9 reference base product number 66461, confirming their functional equivalence within the Multimate III+ series.

Q: What is the Moisture Sensitivity Level rating, and does it differ between these parts?

A: Both contacts carry an MSL rating of 1 (Unlimited), indicating no moisture sensitivity restrictions for storage, handling, or use. This specification is identical across both parts.
