TE Connectivity 641536-3 Rectangular Connector Equivalent & Substitute Parts

Part Overview

The TE Connectivity 641536-3 is a 3-position rectangular receptacle connector from the MTA-100 series, designed for IDC (Insulation Displacement Contact) termination with 26 AWG discrete or ribbon cable. This connector features tin-lead contact finish and is classified as a closed-end receptacle with free hanging or right-angle mounting capability using a locking ramp fastening mechanism.

The part is currently active in production with 1090 units in stock. Identification of equivalent and substitute parts is necessary for procurement flexibility, supply chain continuity, and compliance with evolving regulatory requirements such as RoHS standards.

Substitute Part Grouping Explanation

Substitution between the main part 641536-3 and the equivalent part 3-641536-3 is based on electrical and mechanical compatibility within the MTA-100 series. Both parts maintain identical specifications across the following critical parameters:

Connector type (Receptacle)
Number of positions (3)
Pitch (0.100" / 2.54mm)
Contact type (Female Socket)
Cable termination method (IDC)
Wire gauge (26 AWG)
Mounting type (Free Hanging In-Line, Right Angle)
Fastening type (Locking Ramp)
Contact finish thickness (80.0µin / 2.03µm)
Moisture sensitivity level (MSL 1 - Unlimited)
Color (Blue)

The primary difference between these parts is the contact finish composition (tin-lead versus tin) and RoHS compliance status. Both parts share the same base product number (641536) and are manufactured by TE Connectivity AMP Connectors.

Engineering Selection Recommendations

For applications requiring RoHS3 compliance: Part 3-641536-3 is the appropriate selection. This part meets ROHS3 compliance requirements while maintaining full electrical and mechanical compatibility with the original 641536-3 specification.

For legacy systems or applications without RoHS requirements: Part 641536-3 remains suitable and is available in current inventory (1090 units).

For new designs: Part 3-641536-3 is recommended as the primary selection due to its RoHS3 compliance status, which aligns with current regulatory standards and future supply chain requirements. The substitute part maintains identical mechanical fit, electrical performance, and termination characteristics.

Both parts are active products manufactured by TE Connectivity AMP Connectors and share identical packaging classifications within the MTA-100 series. The contact finish difference (tin-lead versus tin) does not affect mechanical or electrical compatibility for IDC termination applications at 26 AWG.

Frequently Asked Questions (FAQ)

Q: Are 641536-3 and 3-641536-3 mechanically interchangeable?

A: Yes. Both parts are 3-position rectangular receptacles with identical pitch (0.100"), mounting type (free hanging in-line and right angle), and fastening mechanism (locking ramp). They occupy the same physical footprint and accept the same IDC-terminated 26 AWG cables.

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

A: The main part (641536-3) features tin-lead contact finish, while the substitute (3-641536-3) features tin contact finish. Both maintain the same contact finish thickness (80.0µin / 2.03µm) and provide equivalent electrical performance for IDC applications. The tin finish in the substitute part enables RoHS3 compliance.

Q: Can I use 3-641536-3 as a direct replacement for 641536-3?

A: Yes, for applications where RoHS3 compliance is required or acceptable. The substitute part is electrically and mechanically equivalent and will function identically in circuits designed for the original part.

Q: What is the inventory status for each part?

A: Part 641536-3 has 1090 units in stock. Part 3-641536-3 has 5466 units in stock. Both are classified as new original inventory.

Q: Are there any differences in packaging between these parts?

A: The main part (641536-3) packaging is listed as unspecified. The substitute part (3-641536-3) is packaged in bulk. Both parts share the same base product number (641536) and series designation (MTA-100).

Q: Which part should I specify for new designs?

A: Part 3-641536-3 is recommended for new designs due to ROHS3 compliance status. This ensures alignment with current regulatory requirements and provides better long-term supply chain stability.

Q: Are both parts suitable for discrete and ribbon cable termination?

A: Yes. Both parts support IDC termination for discrete or ribbon cable at 26 AWG wire gauge.
