TE Connectivity 1-640441-5 Rectangular Connector Equivalent & Substitute Parts

Part Overview

The TE Connectivity 1-640441-5 is a 15-position rectangular receptacle connector from the MTA-100 series, designed for IDC (Insulation Displacement Contact) termination with 24 AWG discrete or ribbon cable. This connector features tin-lead contact finish and is classified as obsolete. Due to its obsolete product status, identifying equivalent substitute parts is necessary to maintain design continuity and ensure component availability for ongoing production and field service applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 1-640441-5 is determined by strict equivalence across the following critical parameters:

Electrical Compatibility Parameters:

• Connector type (Receptacle)
• Contact type (Female Socket)
• Number of positions (15)
• Pitch (0.100" / 2.54mm)
• Number of rows (1)
• Cable termination method (IDC)
• Wire gauge compatibility (24 AWG)
• Contact finish thickness (80.0µin / 2.03µm)

Mechanical Compatibility Parameters:

• Mounting type (Free Hanging In-Line, Right Angle)
• Fastening type (Locking Ramp)
• Features (Closed End)
• Series designation (MTA-100)

Functional Equivalence: The substitute part 4-640441-5 maintains identical electrical and mechanical specifications to the main part. The primary difference is the contact finish material (tin versus tin-lead) and product status (active versus obsolete). Both parts are manufactured by TE Connectivity AMP Connectors and belong to the same MTA-100 series.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: 4-640441-5

The 4-640441-5 is the direct functional equivalent of the 1-640441-5. Both connectors share identical electrical and mechanical specifications within the MTA-100 series. The 4-640441-5 is the recommended substitute based on the following factors:

Product Status: The 4-640441-5 maintains active product status, ensuring continued availability and manufacturer support. The 1-640441-5 is classified as obsolete, making the 4-640441-5 the appropriate long-term solution for new designs and ongoing production.

Regulatory Compliance: The 4-640441-5 is ROHS3 compliant, meeting current environmental and regulatory requirements. The 1-640441-5 is RoHS non-compliant. For applications subject to RoHS regulations, the 4-640441-5 is the required selection.

Contact Finish Specification: The primary material difference is the contact finish. The 1-640441-5 uses tin-lead finish, while the 4-640441-5 uses tin finish. Both maintain identical contact finish thickness (80.0µin / 2.03µm), ensuring equivalent electrical performance and contact resistance characteristics.

Inventory Availability: The 4-640441-5 has higher inventory availability (1334 pcs) compared to the 1-640441-5 (925 pcs), supporting supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Are the 1-640441-5 and 4-640441-5 electrically interchangeable?

A: Yes. Both connectors are electrically equivalent. They share identical specifications for number of positions (15), pitch (0.100"), contact type (female socket), wire gauge (24 AWG), and contact finish thickness (80.0µin). The contact finish material difference (tin-lead versus tin) does not affect electrical interchangeability.

Q: What is the significance of the contact finish difference between tin-lead and tin?

A: Both tin-lead and tin finishes provide equivalent electrical performance and contact resistance at the specified finish thickness of 80.0µin (2.03µm). The tin finish in the 4-640441-5 reflects compliance with RoHS3 regulations, which restrict lead content in electronic components.

Q: Can the 4-640441-5 be used as a direct replacement in existing designs using the 1-640441-5?

A: Yes. The 4-640441-5 is a direct functional substitute. It maintains identical mechanical mounting characteristics (free hanging in-line, right angle), fastening type (locking ramp), and cable termination method (IDC for 24 AWG wire). No design modifications are required.

Q: What does the product status difference (obsolete versus active) mean for component sourcing?

A: The 1-640441-5 is classified as obsolete, indicating that TE Connectivity has discontinued active production and support. The 4-640441-5 is active, meaning it is currently manufactured and supported by TE Connectivity. For new designs and long-term production, the active 4-640441-5 is the appropriate selection.

Q: Are there any packaging differences between these parts?

A: The 1-640441-5 packaging specification is not provided. The 4-640441-5 is supplied in bulk packaging. Confirm packaging requirements with your procurement specifications.

Q: Does the RoHS compliance difference affect compatibility?

A: RoHS compliance is a regulatory requirement, not a functional compatibility factor. The 4-640441-5 is ROHS3 compliant, making it suitable for applications subject to RoHS regulations. The 1-640441-5 is RoHS non-compliant. For regulated applications, the 4-640441-5 is the required selection.

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

A: Both connectors have a Moisture Sensitivity Level (MSL) of 1 (Unlimited), indicating no moisture sensitivity restrictions for storage, handling, or use.
