Equivalent & Substitute Parts for TE Connectivity 640434-5

Part Overview

The TE Connectivity 640434-5 is a 5-position rectangular receptacle connector from the MTA-156 series, designed for IDC (Insulation Displacement Contact) termination with 24 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 procurement requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 640434-5 is determined by strict equivalence across the following parameters:

• Connector Type and Series: Both parts must be rectangular receptacles from the MTA-156 series
• Position Count and Pitch: 5-position configuration at 0.156" (3.96mm) pitch
• Termination Method: IDC cable termination capability
• Wire Gauge Compatibility: 24 AWG wire gauge support
• Contact Configuration: Female socket contacts with closed-end design
• Mounting and Physical Form: Free hanging in-line mounting with single-row layout
• Contact Finish Thickness: 80.0µin (2.03µm) plating thickness

The substitute part 3-640434-5 maintains all these parameters while offering improved compliance status and active product availability.

Parameter Comparison

Engineering Selection Recommendations

The 3-640434-5 serves as the direct functional equivalent to the obsolete 640434-5. Selection between these parts is determined by regulatory and procurement requirements:

For New Designs and Active Programs: The 3-640434-5 is the appropriate selection. This part maintains identical electrical and mechanical specifications while offering active product status and ROHS3 compliance. The transition from tin-lead to tin contact finish does not affect electrical performance or mechanical compatibility within the specified 24 AWG wire gauge and IDC termination parameters.

For Legacy System Maintenance: The 640434-5 remains available in inventory (1031 pieces) for applications requiring exact historical specification matching. However, the 3-640434-5 (763 pieces in stock) provides equivalent functionality with improved compliance posture.

Compliance Considerations: The 640434-5 is RoHS non-compliant and REACH-affected. The 3-640434-5 achieves ROHS3 compliance, making it the preferred choice for applications subject to environmental regulations or customer compliance requirements.

Frequently Asked Questions (FAQ)

Q: Can the 3-640434-5 directly replace the 640434-5 in existing assemblies?

A: Yes. Both parts are identical in connector type, position count, pitch, termination method, wire gauge, and mounting configuration. The 3-640434-5 is mechanically and electrically interchangeable with the 640434-5.

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

A: Both finishes provide equivalent electrical conductivity and contact performance at the specified 80.0µin (2.03µm) thickness. The tin finish of the 3-640434-5 eliminates lead content, enabling ROHS3 compliance.

Q: Are there packaging differences between these parts?

A: The 640434-5 packaging is not specified in available data. The 3-640434-5 is supplied in bulk packaging. Confirm packaging requirements with procurement specifications.

Q: Why is the 640434-5 classified as obsolete?

A: Obsolescence reflects TE Connectivity's product lifecycle management. The 3-640434-5 represents the active continuation of this connector family within the MTA-156 series.

Q: Can these connectors be used with both discrete and ribbon cable?

A: Yes. Both parts support discrete or ribbon cable termination via IDC at 24 AWG wire gauge.

Q: What is the moisture sensitivity level for these connectors?

A: Both parts carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.

Q: Are there any restrictions on the geographic use of these parts?

A: Both parts carry ECCN classification EAR99, indicating standard commercial export controls. REACH status differs: the 640434-5 is REACH-affected; the 3-640434-5 shows vendor undefined status. Confirm REACH compliance requirements with your supplier for the 3-640434-5.
