TE Connectivity 1-640440-7 Equivalent & Substitute Parts

Part Overview

The TE Connectivity 1-640440-7 is a 17-position rectangular receptacle connector from the MTA-100 series, designed for IDC (Insulation Displacement Contact) termination with 22 AWG discrete or ribbon cable. This connector features tin-lead contact finish, a closed-end design, and a locking ramp fastening mechanism. The part is classified as Active product status with RoHS compliance and unlimited moisture sensitivity rating (MSL 1). Substitute parts are identified when equivalent electrical and mechanical specifications are maintained while packaging, contact finish composition, or compliance certifications differ.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1-640440-7 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Connector type (Receptacle)
• Number of positions (17)
• Pitch (0.100" / 2.54mm)
• Number of rows (1)
• Contact type (Female Socket)
• Cable termination method (IDC)
• Wire gauge (22 AWG)
• Wire type compatibility (Discrete or Ribbon Cable)
• Mounting type (Free Hanging In-Line, Right Angle)
• Fastening type (Locking Ramp)
• Features (Closed End)
• Contact finish thickness (80.0µin / 2.03µm)
• Color (Red)
• Series designation (MTA-100)
• Moisture sensitivity level (MSL 1)

Variable Parameters Permitting Substitution:

• Contact finish composition (Tin-Lead vs. Tin)
• Packaging configuration (standard vs. bulk)
• RoHS compliance variant (RoHS vs. ROHS3)
• REACH status classification

The substitute part 4-640440-7 maintains full electrical and mechanical compatibility with the main part while differing in contact finish material and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

Primary Part Selection (1-640440-7): The 1-640440-7 is suitable for applications requiring RoHS compliance with tin-lead contact finish. This part maintains Active product status and is available in standard packaging configuration.

Substitute Part Selection (4-640440-7): The 4-640440-7 provides equivalent electrical and mechanical performance with the following distinctions:

• Contact finish is pure tin rather than tin-lead, eliminating lead content
• ROHS3 compliance certification provides enhanced regulatory alignment
• REACH status is explicitly classified as Unaffected, providing regulatory clarity
• Bulk packaging configuration is available
• Higher inventory availability (1982 units vs. 669 units)

Both parts are Active status products from TE Connectivity AMP Connectors within the MTA-100 series. Selection between these parts is determined by specific compliance requirements, packaging needs, and contact finish material specifications for the application.

Frequently Asked Questions (FAQ)

Q: Are the 1-640440-7 and 4-640440-7 electrically interchangeable?

A: Yes. Both connectors maintain identical electrical specifications including 17-position configuration, 0.100" pitch, 22 AWG wire gauge compatibility, and IDC termination method. The contact finish thickness is equivalent at 80.0µin (2.03µm) for both parts.

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

A: The 1-640440-7 features tin-lead contact finish, while the 4-640440-7 features pure tin finish. Both finishes are applied to the same thickness specification (80.0µin / 2.03µm). The contact finish material does not affect mechanical compatibility or mating characteristics.

Q: Can I use the 4-640440-7 as a direct replacement for the 1-640440-7?

A: The 4-640440-7 is mechanically and electrically compatible with the 1-640440-7. Selection depends on compliance requirements. The 4-640440-7 provides ROHS3 compliance and explicit REACH Unaffected status, while the 1-640440-7 provides RoHS compliance with vendor-undefined REACH status.

Q: What does MSL 1 (Unlimited) mean for these connectors?

A: MSL 1 indicates the lowest moisture sensitivity level, meaning these connectors have unlimited shelf life and do not require special moisture-controlled storage conditions.

Q: Are both parts available in the same packaging options?

A: No. The 1-640440-7 is supplied in standard packaging, while the 4-640440-7 is supplied in bulk packaging. Packaging selection should align with procurement and assembly requirements.

Q: Which part should I select for new designs?

A: Selection is based on specific application requirements. The 4-640440-7 offers higher inventory availability and explicit REACH compliance status. The 1-640440-7 is suitable where tin-lead contact finish is specified. Both parts are Active status products suitable for production use.

Q: Do these connectors support both discrete and ribbon cable termination?

A: Yes. Both the 1-640440-7 and 4-640440-7 support IDC termination for discrete or ribbon cable at 22 AWG wire gauge.
