Substitute Part Grouping Explanation

Substitution between the 1-640440-1 and 4-640440-1 is valid based on the following critical parameters that remain identical across both parts:

• Connector Type & Position Count: Both are 11-position rectangular receptacles
• Pitch & Row Configuration: Both maintain 0.100" (2.54mm) pitch with single-row layout
• Contact Type & Gender: Both feature female socket contacts
• Cable Termination: Both utilize IDC termination for 22 AWG wire
• Mounting & Fastening: Both support free-hanging and right-angle mounting with locking ramp fastening
• Physical Features: Both are closed-end connectors in red color
• Contact Finish Thickness: Both specify 80.0µin (2.03µm) contact finish thickness

The primary difference between these parts is the contact finish material and RoHS compliance status. The 1-640440-1 features tin-lead contact finish and is RoHS non-compliant, while the 4-640440-1 features tin contact finish and is RoHS3 compliant. Both parts share the same base product number (640440) and series designation (MTA-100), confirming their functional equivalence.

Parameter Comparison

Engineering Selection Recommendations

1-640440-1 Selection Criteria:

The 1-640440-1 is appropriate for applications where RoHS compliance is not a regulatory requirement. This part is active and maintains full inventory availability with 887 units in stock. The tin-lead contact finish provides established performance characteristics in legacy systems and applications predating RoHS mandates.

4-640440-1 Selection Criteria:

The 4-640440-1 is the appropriate selection for applications subject to RoHS3 compliance requirements, including EU market applications and regulated industries. This part features tin contact finish and maintains RoHS3 compliance certification. With 1527 units in stock, the 4-640440-1 offers superior supply chain availability. Both parts are active products with identical functional and mechanical specifications.

Compliance Considerations:

Selection between these parts should be determined by regulatory requirements applicable to the end application. The contact finish difference (tin-lead versus tin) does not affect electrical performance or mechanical compatibility. Both parts maintain identical contact finish thickness (80.0µin) and moisture sensitivity classification (MSL 1).

Frequently Asked Questions (FAQ)

Q: Are the 1-640440-1 and 4-640440-1 mechanically interchangeable?

A: Yes. Both connectors share identical mechanical specifications including pitch (0.100"), position count (11), mounting type (free-hanging and right-angle), and fastening mechanism (locking ramp). Physical dimensions and mating interfaces are equivalent.

Q: What is the functional difference between tin-lead and tin contact finishes?

A: Both contact finishes provide equivalent electrical performance and contact reliability. The primary distinction is regulatory compliance. Tin-lead finish (1-640440-1) is used in non-RoHS applications, while tin finish (4-640440-1) meets RoHS3 requirements. Contact finish thickness is identical at 80.0µin (2.03µm) for both parts.

Q: Can I substitute the 1-640440-1 with the 4-640440-1 in an existing design?

A: Substitution is valid from a functional and mechanical standpoint. However, design documentation and compliance certifications must be updated to reflect the RoHS3 status of the 4-640440-1. Verify that your application's regulatory requirements align with the selected part's compliance status.

Q: What is the significance of the base product number 640440?

A: The base product number 640440 indicates that both the 1-640440-1 and 4-640440-1 are variants of the same core connector design. The prefix digits (1 or 4) differentiate packaging and compliance specifications while maintaining identical electrical and mechanical functionality.

Q: Are both parts suitable for IDC termination with 22 AWG ribbon cable?

A: Yes. Both the 1-640440-1 and 4-640440-1 are specified for IDC termination with 22 AWG discrete or ribbon cable. The IDC termination method and wire gauge specifications are identical across both parts.

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

A: Both parts are classified as MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. These connectors do not require special moisture control during storage, handling, or assembly.

Q: Which part should I select for new designs?

A: For new designs, the 4-640440-1 is the appropriate selection due to its RoHS3 compliance status, which aligns with current regulatory standards and industry best practices. The 4-640440-1 also maintains higher inventory availability (1527 units versus 887 units).
