Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1-640426-3 is determined by strict equivalence across the following critical parameters:

• Connector Type & Contact Configuration: Receptacle with female socket contacts
• Position Count & Pitch: 13 positions at 0.156" (3.96mm) pitch
• Termination Method: IDC cable termination for 18 AWG discrete wire
• Mechanical Interface: Free-hanging in-line mounting with locking ramp fastening
• Contact Material & Finish: Tin plating at 80.0µin (2.03µm) thickness
• Series Designation: MTA-156 series compatibility

The substitute part 4-640426-3 maintains identical electrical and mechanical specifications across all these parameters, differing only in product status (active versus obsolete) and packaging configuration (bulk versus original packaging).

Parameter Comparison

Engineering Selection Recommendations

The 4-640426-3 serves as the direct functional equivalent to the obsolete 1-640426-3. Both parts share identical electrical and mechanical specifications within the MTA-156 rectangular connector series.

Product Status Consideration: The 1-640426-3 is classified as obsolete, while the 4-640426-3 maintains active product status. For new designs and ongoing production applications, the 4-640426-3 is the appropriate selection to ensure long-term component availability and supply chain continuity.

Compliance Status: The 4-640426-3 achieves ROHS3 compliance, whereas the 1-640426-3 is RoHS non-compliant. Applications subject to RoHS regulatory requirements must utilize the 4-640426-3. Both parts maintain identical ECCN (EAR99) and HTSUS (8536.69.8000) classifications.

Packaging Difference: The 1-640426-3 is supplied in original manufacturer packaging, while the 4-640426-3 is supplied in bulk packaging. This distinction affects inventory management and handling procedures but does not alter connector functionality or electrical performance.

Frequently Asked Questions (FAQ)

Q: Are the 1-640426-3 and 4-640426-3 electrically interchangeable?
