TE Connectivity 640605-9 Rectangular Connector Equivalent & Substitute Parts

Part Overview

The TE Connectivity 640605-9 is a 9-position rectangular receptacle connector from the MTA-156 series, designed for IDC (Insulation Displacement Contact) termination with 20 AWG discrete or ribbon cable. This connector features tin-lead contact finish and is classified as obsolete. Due to its obsolete product status and RoHS non-compliant classification, identification of equivalent active alternatives is necessary for ongoing design support and procurement continuity.

Substitute Part Grouping Explanation

Substitution of the 640605-9 is based on electrical and mechanical compatibility within the MTA-156 series. The substitute part 3-640605-9 maintains identical specifications across all critical parameters: 9-position configuration, 0.156" pitch, single-row layout, female socket contact type, IDC termination, 20 AWG wire gauge support, and free-hanging in-line mounting. Both connectors are manufactured by TE Connectivity AMP Connectors and share the same base product number (640605).

The primary distinction between the main part and its substitute is the contact finish specification and product status. The 640605-9 features tin-lead contact finish and carries obsolete status with RoHS non-compliance. The substitute part 3-640605-9 features tin contact finish and maintains active product status with RoHS compliance. These differences do not affect mechanical or electrical interchangeability for applications requiring 9-position, 0.156" pitch IDC receptacle connectors rated for 20 AWG cable.

Parameter Comparison

Engineering Selection Recommendations

The 3-640605-9 is the direct equivalent substitute for the obsolete 640605-9. Selection of the substitute part is supported by the following factors:

Product Status: The 640605-9 is classified as obsolete, whereas the 3-640605-9 maintains active product status. Active status ensures continued availability, manufacturing support, and supply chain reliability.

Regulatory Compliance: The 640605-9 is RoHS non-compliant, while the 3-640605-9 is RoHS compliant. For applications subject to RoHS directives or customer requirements mandating RoHS compliance, the substitute part satisfies regulatory obligations.

Mechanical and Electrical Compatibility: Both parts maintain identical specifications for all functional parameters including connector geometry, contact configuration, pitch, termination method, and wire gauge rating. The parts are mechanically and electrically interchangeable within applications designed for 9-position, 0.156" pitch IDC receptacle connectors.

Contact Finish Consideration: The substitute part features tin contact finish compared to the tin-lead finish of the main part. Both finishes maintain the same contact finish thickness (80.0µin / 2.03µm) and are suitable for IDC termination applications. The tin finish of the substitute part aligns with RoHS compliance requirements.

Frequently Asked Questions (FAQ)

Q: Are the 640605-9 and 3-640605-9 mechanically interchangeable?

A: Yes. Both connectors share identical mechanical specifications including 9-position configuration, 0.156" pitch, single-row layout, and free-hanging in-line mounting type. They are mechanically interchangeable within applications designed for MTA-156 series 9-position receptacle connectors.

Q: Are the 640605-9 and 3-640605-9 electrically interchangeable?

A: Yes. Both connectors support identical electrical specifications including female socket contact type, IDC termination, 20 AWG wire gauge rating, and feed-through functionality. They are electrically interchangeable for applications requiring these specifications.

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

A: The 640605-9 features tin-lead contact finish, while the 3-640605-9 features tin contact finish. Both finishes maintain the same contact finish thickness (80.0µin / 2.03µm). The tin finish of the substitute part complies with RoHS directives that restrict lead content in electronic components.

Q: Why is the 640605-9 classified as obsolete?

A: The 640605-9 is classified as obsolete by TE Connectivity. The 3-640605-9 is the active equivalent replacement that maintains all functional specifications while providing current product status and RoHS compliance.

Q: Can the 640605-9 be used in new designs?

A: The 640605-9 is obsolete and RoHS non-compliant. For new designs, the 3-640605-9 is the recommended substitute, providing active product status, RoHS compliance, and identical functional specifications.

Q: What packaging is available for the 3-640605-9?

A: The 3-640605-9 is available in bulk packaging, with 1151 pieces in current stock inventory.

Q: Are there any differences in moisture sensitivity between the two parts?

A: No. Both the 640605-9 and 3-640605-9 carry Moisture Sensitivity Level (MSL) 1, indicating unlimited moisture sensitivity rating.

Q: Do both parts support discrete and ribbon cable termination?

A: Yes. Both the 640605-9 and 3-640605-9 support IDC termination for discrete or ribbon cable types rated at 20 AWG.
