Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 640426-5 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Connector type (Receptacle)
• Contact type (Female Socket)
• Number of positions (5)
• Pitch specification (0.156" / 3.96mm)
• Number of rows (1)
• Cable termination method (IDC)
• Wire gauge rating (18 AWG)
• Contact finish material (Tin)
• Mounting configuration (Free Hanging In-Line)
• Fastening mechanism (Locking Ramp)
• Series designation (MTA-156)

Parts meeting all these parameters are classified as direct functional equivalents. Variations in product status, compliance certifications, or packaging do not affect electrical or mechanical interchangeability.

Parameter Comparison

Engineering Selection Recommendations

The 3-640426-5 is a direct functional equivalent to the 640426-5 across all electrical and mechanical parameters. Both connectors share identical specifications for connector type, contact configuration, pitch, termination method, and wire gauge rating.

Product Status Consideration: The 640426-5 is classified as obsolete, while the 3-640426-5 maintains active product status. For new designs, ongoing production, and field service applications, the 3-640426-5 is the appropriate selection to ensure continued availability and manufacturer support.

Compliance Consideration: The 3-640426-5 is ROHS3 compliant, whereas the 640426-5 is RoHS non-compliant. Applications subject to RoHS regulatory requirements must utilize the 3-640426-5. For legacy systems or applications without RoHS mandates, either part satisfies the functional requirements.

Packaging Consideration: The 640426-5 is supplied in standard packaging, while the 3-640426-5 is supplied in bulk packaging. Packaging selection depends on procurement volume and inventory management requirements and does not affect connector performance or compatibility.

Frequently Asked Questions (FAQ)

Q: Are the 640426-5 and 3-640426-5 electrically and mechanically interchangeable?

A: Yes. Both connectors are identical in all electrical and mechanical specifications, including contact type, number of positions, pitch, wire gauge rating, termination method, and fastening mechanism. They are direct functional equivalents.

Q: Why does the 640426-5 show as obsolete?

A: The 640426-5 has been superseded by the 3-640426-5 in the manufacturer's product line. The 3-640426-5 is the active equivalent part and is the recommended selection for all applications.

Q: What is the difference between the 640426-5 and 3-640426-5?

A: The primary differences are product status (obsolete versus active), RoHS compliance (non-compliant versus ROHS3 compliant), and packaging format (standard versus bulk). All electrical and mechanical parameters are identical.

Q: Can I use the 3-640426-5 as a replacement for the 640426-5 in existing designs?

A: Yes. The 3-640426-5 is a direct substitute with identical connector specifications. No design modifications are required. The substitution is valid for new production, field service, and retrofit applications.

Q: Does the RoHS compliance difference affect connector performance?

A: No. RoHS compliance relates to material composition and environmental regulations, not electrical or mechanical performance. Both connectors deliver identical functional performance. RoHS compliance is a regulatory and procurement consideration.

Q: Are there any compatibility issues with the bulk packaging of the 3-640426-5?

A: No. Packaging format does not affect connector compatibility or performance. Bulk packaging is a supply and inventory consideration only. The connector itself is identical regardless of packaging type.

Q: What wire gauge does this connector support?

A: Both the 640426-5 and 3-640426-5 are rated for 18 AWG discrete wire termination using IDC technology.

Q: What is the pitch specification for this connector?

A: The pitch is 0.156" (3.96mm), which is the standard spacing for the MTA-156 series rectangular connectors.
