TE Connectivity 640623-5 Rectangular Connector Equivalent & Substitute Parts

Part Overview

The TE Connectivity 640623-5 is a 5-position rectangular receptacle connector from the MTA-100 series, designed for IDC (Insulation Displacement Contact) termination with 28 AWG discrete or ribbon cable. This connector features tin-lead contact finish and is classified as a feed-through component with free hanging in-line and right-angle mounting options. The part is currently active in production with 915 pieces available in new original inventory.

Substitute parts are identified when equivalent electrical and mechanical specifications are maintained across connector geometry, termination method, contact configuration, and pitch standards. Alternative part numbers may be necessary due to inventory availability, packaging requirements, or compliance status differences.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TE Connectivity 640623-5 is determined by strict equivalence across the following parameters:

Critical Matching Parameters:

• Connector type (Receptacle)
• Number of positions (5)
• Pitch specification (0.100" / 2.54mm)
• Number of rows (1)
• Contact type (Female Socket)
• Cable termination method (IDC)
• Wire gauge compatibility (28 AWG)
• Mounting configuration (Free Hanging In-Line, Right Angle)
• Fastening mechanism (Locking Ramp)
• Wire type support (Discrete or Ribbon Cable)
• Feed-through feature

The substitute part 3-640623-5 maintains complete electrical and mechanical equivalence across all critical parameters. The primary difference between the main part and its substitute is the contact finish specification (tin-lead versus tin) and the resulting RoHS compliance status. Both parts share the same base product number (640623) and series designation (MTA-100), confirming their functional interchangeability within the MTA-100 rectangular connector family.

Parameter Comparison

Engineering Selection Recommendations

640623-5 (Tin-Lead Contact Finish): This part is suitable for applications where RoHS compliance is not a requirement. The tin-lead contact finish provides established performance characteristics in legacy systems and non-regulated environments. The part maintains active production status with adequate inventory availability.

3-640623-5 (Tin Contact Finish): This part is the appropriate selection for applications requiring RoHS compliance. The tin contact finish meets regulatory requirements while maintaining identical electrical and mechanical specifications to the main part. The substitute offers higher inventory availability (2100 pieces) and bulk packaging options, making it suitable for production environments with compliance mandates.

Both parts are functionally interchangeable within the MTA-100 series and share identical connector geometry, termination methodology, and electrical performance characteristics. Selection between these parts is determined by regulatory compliance requirements and packaging preferences rather than technical performance differences.

Frequently Asked Questions (FAQ)

Q: Are the 640623-5 and 3-640623-5 connectors mechanically interchangeable?

A: Yes. Both connectors maintain identical mechanical specifications including 5-position configuration, 0.100" pitch, female socket contact type, IDC termination, and locking ramp fastening. They are directly interchangeable in applications where the contact finish material does not affect system requirements.

Q: What is the primary difference between these two parts?

A: The primary difference is the contact finish material. The 640623-5 uses tin-lead finish and is RoHS non-compliant, while the 3-640623-5 uses tin finish and is RoHS compliant. Both finishes are applied to the same 80.0µin (2.03µm) thickness specification.

Q: Can I use the 3-640623-5 as a direct replacement for the 640623-5 in existing designs?

A: Yes, the 3-640623-5 is a direct functional replacement. The tin contact finish of the substitute part is compatible with all IDC termination methods and mounting configurations specified for the original part. No design modifications are required.

Q: What is the significance of the base product number 640623?

A: The base product number 640623 identifies the core connector design within the MTA-100 series. Both the 640623-5 and 3-640623-5 share this base number, confirming they are variants of the same fundamental connector platform with identical electrical and mechanical characteristics.

Q: Are there packaging differences between these parts?

A: Yes. The 640623-5 packaging is not specified in the available data, while the 3-640623-5 is supplied in bulk packaging. The 3-640623-5 also has higher inventory availability (2100 pieces versus 915 pieces), making it preferable for high-volume production requirements.

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

A: Yes. Both the 640623-5 and 3-640623-5 support IDC termination for discrete or ribbon cable at 28 AWG wire gauge. The cable termination capability is identical across both parts.

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

A: Both parts have a Moisture Sensitivity Level (MSL) of 1, which indicates unlimited moisture sensitivity tolerance. No special moisture control measures are required during storage or handling.
