TE Connectivity 1-640622-5 Rectangular Connector Equivalent & Substitute Parts

Part Overview

The TE Connectivity 1-640622-5 is a 15-position rectangular receptacle connector from the MTA-100 series, designed for IDC (Insulation Displacement Contact) termination with 26 AWG discrete or ribbon cable. This connector features tin-lead contact finish and is configured as a free-hanging, right-angle mounted receptacle with locking ramp fastening.

The 1-640622-5 is classified as obsolete. Locating equivalent substitute parts is necessary to support ongoing maintenance, repair, and replacement requirements for legacy systems and equipment utilizing this connector configuration.

Substitute Part Grouping Explanation

Substitution eligibility for the 1-640622-5 is determined by strict equivalence across the following critical parameters:

Connector Type & Position Count: Receptacle configuration with 15 positions
Pitch & Row Configuration: 0.100" (2.54mm) pitch, single-row layout
Mounting & Fastening: Free-hanging, right-angle orientation with locking ramp fastening
Cable Termination Method: IDC termination for 26 AWG wire
Series Compatibility: MTA-100 series designation
Contact Finish Specification: Tin or tin-lead plating acceptable within MTA-100 series parameters

The substitute part 4-640622-5 maintains full electrical and mechanical compatibility with the original 1-640622-5 across all specified parameters. The primary distinction is the contact finish composition (tin versus tin-lead) and product status (active versus obsolete).

Engineering Selection Recommendations

The 4-640622-5 is the direct substitute for the obsolete 1-640622-5. Both connectors share identical electrical and mechanical specifications within the MTA-100 series, ensuring functional interchangeability in applications requiring 15-position IDC receptacle connectors with 26 AWG wire termination.

The 4-640622-5 offers the following advantages:

Active Product Status: Currently manufactured and supported by TE Connectivity, ensuring availability for ongoing procurement
RoHS3 Compliance: Meets current environmental and regulatory requirements, whereas the original 1-640622-5 is RoHS non-compliant
Contact Finish: Tin plating provides equivalent electrical performance and corrosion resistance compared to tin-lead, with identical finish thickness specification

Selection of the 4-640622-5 is appropriate for new designs, system upgrades, and replacement applications where regulatory compliance and long-term component availability are required.

Frequently Asked Questions (FAQ)

Q: Are the 1-640622-5 and 4-640622-5 mechanically interchangeable?

A: Yes. Both connectors maintain identical pitch (0.100"), position count (15), mounting configuration (free-hanging, right-angle), and fastening mechanism (locking ramp). Physical dimensions and mating interfaces are equivalent.

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

A: The 1-640622-5 features tin-lead plating, while the 4-640622-5 uses tin plating. Both finishes are applied at 80.0µin (2.03µm) thickness. Tin plating provides equivalent electrical conductivity and corrosion resistance for IDC applications. The tin finish in the 4-640622-5 supports RoHS3 compliance.

Q: Can the 4-640622-5 be used as a direct replacement in legacy equipment designed for the 1-640622-5?

A: Yes. The 4-640622-5 is electrically and mechanically equivalent to the 1-640622-5. IDC termination compatibility, wire gauge acceptance (26 AWG), and connector geometry are identical. The substitute part functions identically in existing applications.

Q: Why is the 1-640622-5 classified as obsolete?

A: The 1-640622-5 is no longer in active production. The 4-640622-5 represents the current active equivalent within the MTA-100 series, offering improved regulatory compliance and sustained manufacturing support.

Q: What is the significance of RoHS3 compliance for the 4-640622-5?

A: RoHS3 compliance indicates the 4-640622-5 meets current European Union and international environmental regulations restricting hazardous substances. This certification is required for equipment sold in regulated markets and is essential for new system designs and long-term component sourcing.

Q: Are both connectors suitable for ribbon cable and discrete wire termination?

A: Yes. Both the 1-640622-5 and 4-640622-5 support IDC termination for discrete or ribbon cable at 26 AWG wire gauge. The feed-through feature accommodates both termination methods.

Q: What is the Moisture Sensitivity Level (MSL) for these connectors?

A: Both connectors are rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. These connectors do not require special moisture control during storage, handling, or installation.
