Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1-640426-7 is determined by strict equivalence across the following critical parameters:

• Connector Type & Contact Configuration: Receptacle with female socket contacts
• Position Count & Pitch: 17 positions at 0.156" (3.96mm) pitch
• Row Configuration: Single row layout
• 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
• Physical Design: Closed-end housing in orange color
• Series Designation: MTA-156 series compatibility

Parts meeting all these parameters are classified as direct functional equivalents and may be substituted without modification to mating connector interfaces, cable assemblies, or PCB layouts.

Parameter Comparison

Engineering Selection Recommendations

Frequently Asked Questions (FAQ)

Q: Can the 4-640426-7 be used as a direct replacement for the 1-640426-7 in existing assemblies?

A: Yes. The 4-640426-7 is electrically and mechanically equivalent to the 1-640426-7 across all functional parameters. No modifications to mating connectors, cable assemblies, or circuit board layouts are required.

Q: What is the primary difference between these two part numbers?

A: The 1-640426-7 is obsolete, while the 4-640426-7 is an active product. Additionally, the 4-640426-7 is RoHS compliant, whereas the 1-640426-7 is RoHS non-compliant. All electrical and mechanical specifications are identical.

Q: Are there packaging differences between the 1-640426-7 and 4-640426-7?

A: The 1-640426-7 packaging specification is not defined in the available data. The 4-640426-7 is supplied in bulk packaging. Contact the supplier for specific packaging requirements or configurations.

Q: Does the RoHS compliance difference affect connector performance?

A: RoHS compliance relates to material composition and regulatory adherence, not electrical or mechanical performance. Both parts function identically in circuit applications. RoHS compliance is a regulatory and procurement consideration.

Q: What wire gauge and termination method are supported by these connectors?

A: Both connectors support 18 AWG discrete wire with IDC (Insulation Displacement Contact) termination. The IDC method allows direct wire insertion without pre-stripping.

Q: Are these connectors suitable for new product designs?

A: The 4-640426-7 is recommended for new designs due to its active product status and RoHS compliance. The 1-640426-7, being obsolete, is suitable only for replacement or maintenance of existing systems.

Q: What is the pitch specification, and why is it important?

A: The pitch is 0.156" (3.96mm), representing the center-to-center distance between adjacent contact positions. This specification determines mechanical compatibility with mating connectors and must be matched exactly for proper interface.
