TE Connectivity 641522-4 Rectangular Connector Equivalent & Substitute Parts

Part Overview

The TE Connectivity 641522-4 is a 4-position rectangular plug connector from the MTA-156 series, designed for IDC (Insulation Displacement Contact) termination with 18 AWG discrete or ribbon cable. This connector features tin-lead contact finish and is configured as a free-hanging, in-line or right-angle mounted plug with male pin contacts. The part is currently active in production with 1034 units in stock.

Substitute parts are identified when equivalent electrical and mechanical specifications are maintained across connector position count, pitch, contact type, cable termination method, and wire gauge. Alternative part numbers may offer improved compliance status or different packaging configurations while preserving functional compatibility.

Substitute Part Grouping Explanation

The substitute part 3-641522-4 is functionally equivalent to the main part 641522-4 based on the following critical parameters that determine substitution eligibility:

Electrical and Mechanical Compatibility Criteria:

• Identical number of positions (4)
• Identical pitch specification (0.156" / 3.96mm)
• Identical contact type (Male Pin)
• Identical cable termination method (IDC)
• Identical wire gauge (18 AWG)
• Identical wire type support (Discrete or Ribbon Cable)
• Identical mounting configuration (Free Hanging, In-Line, Right Angle)
• Identical series designation (MTA-156)
• Identical contact finish thickness (80.0µin / 2.03µm)

The primary difference between these parts is the contact finish composition and associated compliance status. Part 3-641522-4 features tin contact finish and is RoHS compliant, whereas the main part 641522-4 uses tin-lead contact finish and is RoHS non-compliant. Both parts maintain identical electrical performance and mechanical interface specifications.

Parameter Comparison

Engineering Selection Recommendations

Part 641522-4 (Tin-Lead Contact Finish): Select this part when RoHS non-compliant components are acceptable for the application and REACH-affected materials are permitted. This part maintains active production status and is suitable for legacy systems or applications without regulatory compliance requirements.

Part 3-641522-4 (Tin Contact Finish): Select this part for applications requiring RoHS compliance and REACH-unaffected material composition. This substitute maintains identical electrical and mechanical specifications while providing improved regulatory compliance status. Higher inventory availability (2399 units) supports production scheduling requirements. Bulk packaging configuration is available for this part.

Both parts are active products from TE Connectivity AMP Connectors and are suitable for direct substitution based on connector interface specifications. Selection between these parts is determined by regulatory compliance requirements and packaging preferences rather than electrical or mechanical performance differences.

Frequently Asked Questions (FAQ)

Q: Can part 3-641522-4 be used as a direct replacement for 641522-4?

A: Yes. Part 3-641522-4 is a direct substitute for 641522-4. Both parts maintain identical connector interface specifications including position count, pitch, contact type, cable termination method, wire gauge, and mounting configuration. The primary difference is the contact finish material (tin versus tin-lead) and associated compliance certifications.

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

A: Both contact finishes are applied at identical thickness (80.0µin / 2.03µm) and provide equivalent electrical performance. The tin-lead finish in part 641522-4 is RoHS non-compliant and REACH-affected. The tin finish in part 3-641522-4 is RoHS compliant and REACH-unaffected. Contact finish selection is driven by regulatory requirements rather than electrical characteristics.

Q: Are these connectors compatible with both discrete and ribbon cable?

A: Yes. Both parts support discrete or ribbon cable termination via IDC (Insulation Displacement Contact) method at 18 AWG wire gauge. The connector accommodates either cable type without modification.

Q: What does the 0.156" pitch specification mean?

A: The 0.156" (3.96mm) pitch specifies the center-to-center distance between adjacent contact positions. This pitch is standardized for the MTA-156 series and determines mechanical compatibility with mating connectors and cable assemblies.

Q: Can these connectors be mounted in different orientations?

A: Yes. Both parts support free-hanging mounting in either in-line or right-angle configurations. The mounting orientation is determined during assembly and does not affect electrical performance or substitution eligibility.

Q: What is the significance of MSL 1 (Unlimited) rating?

A: MSL 1 (Moisture Sensitivity Level 1) with unlimited shelf life indicates these connectors have minimal moisture sensitivity and do not require special storage or handling conditions. Both parts carry identical MSL ratings.

Q: Does packaging type affect connector performance or compatibility?

A: No. Packaging type (standard versus bulk) does not affect electrical or mechanical performance. Packaging selection is based on procurement and inventory management requirements. Part 3-641522-4 is available in bulk packaging, while part 641522-4 uses standard packaging.

Q: Are both parts currently in production?

A: Yes. Both parts maintain active product status with TE Connectivity AMP Connectors. Part 641522-4 has 1034 units in stock, and part 3-641522-4 has 2399 units in stock.
