TE Connectivity 641524-4 Rectangular Connector Equivalent & Substitute Parts

Part Overview

The TE Connectivity 641524-4 is a 4-position rectangular plug connector from the MTA-156 series, designed for IDC (Insulation Displacement Contact) termination with 22 AWG discrete or ribbon cable. This connector features tin-lead contact finish and is classified as a free-hanging, in-line or right-angle mounted plug with feed-through capability. The part is currently active in production with 810 pieces available in new original inventory.

Substitute parts are identified when equivalent electrical and mechanical parameters are maintained across connector specifications. Alternative part numbers may be necessary due to inventory availability, packaging requirements, or compliance status differences while preserving functional compatibility in the application circuit.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TE Connectivity 641524-4 is determined by strict equivalence across the following critical parameters:

Electrical Compatibility Parameters:

• Connector type (Plug)
• Number of positions (4)
• Contact type (Male Pin)
• Pitch spacing (0.156" / 3.96mm)
• Cable termination method (IDC)
• Wire gauge rating (22 AWG)
• Wire type compatibility (Discrete or Ribbon Cable)

Mechanical Compatibility Parameters:

• Number of rows (1)
• Mounting configuration (Free Hanging, In-Line, Right Angle)
• Series designation (MTA-156)
• Contact finish thickness (80.0µin / 2.03µm)

Environmental & Regulatory Parameters:

• Moisture Sensitivity Level (MSL 1)
• ECCN classification (EAR99)
• HTSUS code (8536.69.4051)

Substitute parts must maintain identical values across all listed parameters. Variations in contact finish material (tin versus tin-lead), packaging format, RoHS compliance status, and REACH classification do not affect functional substitution when all electrical and mechanical parameters remain equivalent.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity 3-641524-4 is a direct functional substitute for the 641524-4 across all critical electrical and mechanical parameters. Both parts maintain identical connector architecture, contact configuration, pitch spacing, and cable termination specifications within the MTA-156 series.

Compliance Considerations:

The 3-641524-4 substitute part carries ROHS3 compliance certification and REACH unaffected status, whereas the original 641524-4 is RoHS non-compliant and REACH affected. Selection between these parts depends on regulatory requirements applicable to the end application and target market. Applications subject to RoHS3 or REACH restrictions require the 3-641524-4 variant.

Contact Finish Difference:

The primary material distinction is the contact finish specification. The 641524-4 features tin-lead plating, while the 3-641524-4 uses tin plating. Both maintain the same 80.0µin (2.03µm) thickness specification. This difference does not affect electrical performance or mechanical compatibility in standard applications.

Packaging and Inventory:

The 3-641524-4 is supplied in bulk packaging with significantly higher inventory availability (2063 pieces versus 810 pieces). Selection based on packaging requirements and supply chain lead time considerations is appropriate.

Both parts are active products with equivalent functional performance in IDC-terminated 4-position rectangular connector applications using 22 AWG discrete or ribbon cable.

Frequently Asked Questions (FAQ)

Q: Can the 3-641524-4 be used as a direct replacement for the 641524-4 in existing designs?

A: Yes. The 3-641524-4 maintains identical electrical and mechanical specifications across all critical parameters including connector type, position count, pitch spacing, contact configuration, cable termination method, and wire gauge rating. Both parts are MTA-156 series plugs with identical mounting and feed-through characteristics.

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

A: The 641524-4 uses tin-lead plating while the 3-641524-4 uses tin plating. Both maintain 80.0µin (2.03µm) thickness. The contact finish material does not affect the mechanical fit, electrical conductivity, or IDC termination performance in standard applications. Selection depends on application-specific material restrictions or environmental requirements.

Q: Are there RoHS or REACH compliance differences between these parts?

A: Yes. The 641524-4 is RoHS non-compliant and REACH affected. The 3-641524-4 is ROHS3 compliant and REACH unaffected. Applications subject to RoHS3 or REACH regulatory requirements must use the 3-641524-4 variant.

Q: Does packaging format affect connector performance?

A: No. Packaging format (bulk versus other configurations) does not affect electrical or mechanical performance. Packaging selection is based on inventory management, supply chain requirements, and handling procedures. Both parts deliver identical connector specifications regardless of packaging method.

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

A: Yes. Both the 641524-4 and 3-641524-4 are specified for IDC termination with discrete or ribbon cable at 22 AWG wire gauge. The IDC contact design and cable termination method are identical across both part numbers.

Q: What is the pitch spacing for these connectors?

A: Both connectors maintain 0.156" (3.96mm) pitch spacing, which is the standard MTA-156 series specification. This pitch is not interchangeable with other connector series and must be matched to corresponding receptacle connectors.

Q: Can these connectors be mounted in different orientations?

A: Both parts support free-hanging mounting in in-line or right-angle configurations. The mounting type is determined by the connector body design and is identical between the 641524-4 and 3-641524-4.
