TE Connectivity 2-640426-4 Equivalent & Substitute Parts

Part Overview

The TE Connectivity 2-640426-4 is a 24 Position Rectangular Receptacle Connector IDC Tin 18 AWG, part of the MTA-156 series. This connector is classified as Obsolete, indicating it is no longer in active production. The connector features a female socket contact type with IDC (Insulation Displacement Contact) cable termination, designed for discrete wire applications at 18 AWG wire gauge. Due to its obsolete status, identifying equivalent substitute parts is necessary for ongoing system maintenance, repair, and new design implementations where legacy compatibility is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TE Connectivity 2-640426-4 is determined by strict equivalence across the following critical parameters:

• Connector Type & Contact Configuration: Receptacle with female socket contacts
• Position Count & Pitch: 24 positions at 0.156" (3.96mm) pitch
• Row Configuration: Single row layout
• Mounting & Fastening: Free hanging in-line mounting with locking ramp fastening
• Cable Termination Method: IDC termination for discrete 18 AWG wire
• Contact Material & Finish: Tin plating at 80.0µin (2.03µm) thickness
• Series Designation: MTA-156 series compatibility

Substitute parts must maintain identical electrical and mechanical specifications across all these parameters to ensure direct interchangeability without design modification or system reconfiguration.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity 5-640426-4 is the direct substitute for the obsolete 2-640426-4 model. Both connectors are manufactured by TE Connectivity AMP Connectors and maintain identical electrical and mechanical specifications across all critical parameters.

Key Differentiation Factors:

The primary distinction between the main part and its substitute is product status and regulatory compliance. The 2-640426-4 is classified as Obsolete and carries RoHS non-compliant status, while the 5-640426-4 is Active and RoHS Compliant. This compliance upgrade makes the 5-640426-4 the appropriate selection for new designs and applications subject to RoHS regulations.

Both connectors share identical connector architecture, contact configuration, pitch, mounting methodology, and termination specifications. The 5-640426-4 is available in Bulk packaging and maintains full inventory availability, supporting immediate procurement for replacement and new implementation requirements.

Frequently Asked Questions (FAQ)

Q: Can the 5-640426-4 directly replace the 2-640426-4 in existing applications?

A: Yes. The 5-640426-4 maintains identical electrical and mechanical specifications including connector type, position count, pitch, mounting configuration, fastening method, cable termination, wire gauge, contact finish, and all other critical parameters. Direct substitution is supported without design modification.

Q: What is the significance of the product status difference between these parts?

A: The 2-640426-4 is classified as Obsolete, indicating discontinued production. The 5-640426-4 is Active, meaning it remains in current production with ongoing availability. For new designs and long-term supply chain planning, the Active status of the 5-640426-4 provides manufacturing continuity and inventory reliability.

Q: How does RoHS compliance affect part selection?

A: The 2-640426-4 is RoHS non-compliant, while the 5-640426-4 is RoHS Compliant. Applications subject to RoHS regulations or customer requirements mandating RoHS compliance must use the 5-640426-4. Both connectors are electrically and mechanically equivalent; the compliance difference reflects regulatory and environmental standards.

Q: Are there packaging differences between these parts?

A: The 2-640426-4 packaging specification is not provided in the technical data. The 5-640426-4 is supplied in Bulk packaging. Packaging differences do not affect connector functionality or interchangeability.

Q: What wire gauge and termination method do these connectors support?

A: Both connectors support 18 AWG discrete wire with IDC (Insulation Displacement Contact) termination. The IDC method provides direct wire insertion without stripping, and both parts maintain identical contact specifications for this termination approach.

Q: Is the MSL rating identical for both parts?

A: Yes. Both the 2-640426-4 and 5-640426-4 carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions during storage or handling.
