TE Connectivity 1-640620-1 Equivalent & Substitute Parts

Part Overview

The TE Connectivity 1-640620-1 is an 11-position rectangular receptacle connector from the MTA-100 series, designed for IDC (Insulation Displacement Contact) termination with 22 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-compliance, identification of active equivalent parts is necessary for new designs and ongoing production requirements.

Parameter Comparison

Engineering Selection Recommendations

The 4-640620-1 serves as the direct substitute for the obsolete 1-640620-1. Selection of the substitute part is based on the following factors:

Product Status: The 1-640620-1 is classified as obsolete, making the active 4-640620-1 the appropriate choice for ongoing production and new designs.

Regulatory Compliance: The 4-640620-1 is ROHS3 compliant, whereas the 1-640620-1 is RoHS non-compliant. This compliance improvement aligns with current regulatory requirements for electronic components in most markets.

Electrical and Mechanical Equivalence: Both parts maintain identical specifications across all critical parameters including connector type, position count, pitch, mounting configuration, termination method, and wire gauge. The contact finish thickness remains constant at 80.0µin (2.03µm).

Contact Finish Difference: The 4-640620-1 features tin contact finish compared to the tin-lead finish of the 1-640620-1. Both finishes maintain the same thickness specification and are compatible with IDC termination for 22 AWG cable.

Environmental Rating: Both parts share identical moisture sensitivity level classification of 1 (Unlimited), indicating equivalent environmental performance.

Frequently Asked Questions (FAQ)

Q: Are the 1-640620-1 and 4-640620-1 mechanically interchangeable?

A: Yes. Both connectors share identical mechanical specifications including 11-position configuration, 0.100" (2.54mm) pitch, free hanging in-line and right angle mounting options, and locking ramp fastening. They are mechanically interchangeable in applications requiring these specifications.

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

A: The 1-640620-1 uses tin-lead contact finish while the 4-640620-1 uses tin contact finish. Both maintain the same thickness of 80.0µin (2.03µm) and are compatible with IDC termination. The tin finish in the 4-640620-1 reflects modern RoHS3 compliance requirements.

Q: Can I use the 4-640620-1 as a direct replacement for the 1-640620-1 in existing designs?

A: Yes. The 4-640620-1 is electrically and mechanically equivalent to the 1-640620-1 across all functional parameters. The primary advantages are active product status and ROHS3 compliance.

Q: Why is the 1-640620-1 listed as obsolete?

A: The 1-640620-1 has been discontinued by TE Connectivity. The 4-640620-1 represents the current active equivalent in the MTA-100 series for this connector configuration.

Q: Are there any packaging differences between these parts?

A: The 1-640620-1 is supplied in standard packaging, while the 4-640620-1 is supplied in bulk packaging. Both parts are identical in form, fit, and function.

Q: What cable types are compatible with both connectors?

A: Both the 1-640620-1 and 4-640620-1 accept discrete or ribbon cable with 22 AWG wire gauge using IDC termination. The feed-through feature allows for daisy-chain configurations.

Q: Do both connectors have the same environmental ratings?

A: Yes. Both connectors share identical moisture sensitivity level classification of 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.
