Substitute Part Grouping Explanation

Substitution between the main part 641436-2 and the identified equivalent 3-641436-2 is based on strict electrical and mechanical compatibility criteria. Both connectors maintain identical specifications across all critical parameters that determine functional interchangeability:

Key Parameters for Substitution Compatibility:

• Connector type, position count, and pitch (0.156")
• Contact type and configuration (male pin, 1 row)
• Cable termination method (IDC) and wire gauge (20 AWG)
• Mounting type and orientation capability
• Contact finish thickness (80.0µin)
• Closed-end design and color (yellow)
• Moisture sensitivity level (MSL 1)

The primary differences between these parts are contact finish composition (tin-lead versus tin) and RoHS compliance status, along with packaging configuration and inventory availability. These differences do not affect the electrical or mechanical interface characteristics.

Parameter Comparison

Engineering Selection Recommendations

For RoHS-Compliant Applications: Select part 3-641436-2. This substitute maintains full electrical and mechanical compatibility with the main part while meeting RoHS compliance requirements. The tin contact finish (versus tin-lead) is compliant with lead-free regulations and provides equivalent contact performance at the specified finish thickness of 80.0µin.

For Non-RoHS Applications: Either part 641436-2 or 3-641436-2 is suitable. The main part 641436-2 with tin-lead finish is appropriate for applications without RoHS restrictions.

For High-Volume Requirements: Part 3-641436-2 offers significantly higher inventory availability (24913 pieces versus 882 pieces), making it the preferred selection for production runs requiring large quantities.

For Packaging Considerations: Part 3-641436-2 is supplied in bulk packaging, while the main part packaging specification is not provided. Bulk packaging is standard for high-volume assembly operations.

Both parts are active products from TE Connectivity AMP Connectors with identical mechanical interfaces, electrical ratings, and functional performance within the MTA-156 series specification.

Frequently Asked Questions (FAQ)

Q: Can 3-641436-2 be used as a direct replacement for 641436-2 in existing designs?

A: Yes. Both connectors are mechanically and electrically identical across all interface parameters including pitch (0.156"), position count (2), contact configuration (male pin), cable termination method (IDC), and wire gauge (20 AWG). The primary differences are contact finish composition and RoHS compliance status, which do not affect connector mating or electrical performance.

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

A: The main part 641436-2 features tin-lead contact finish, while substitute 3-641436-2 features tin finish. Both maintain the same contact finish thickness of 80.0µin (2.03µm). The tin finish in 3-641436-2 is compliant with RoHS regulations that restrict lead content in electronic components.

Q: Is the 3-641436-2 suitable for applications requiring RoHS compliance?

A: Yes. Part 3-641436-2 is marked as RoHS Compliant, making it the appropriate selection for applications subject to RoHS requirements. The main part 641436-2 is RoHS non-compliant due to its tin-lead contact finish.

Q: Are there any performance differences between these two connectors?

A: No. Both connectors provide identical electrical performance, contact resistance, and mechanical durability. The contact finish thickness, moisture sensitivity level, and all functional specifications are equivalent.

Q: What packaging options are available?

A: Part 3-641436-2 is supplied in bulk packaging. The packaging specification for the main part 641436-2 is not provided in the technical data.

Q: Which part should be selected for new designs?

A: For new designs, part 3-641436-2 is recommended due to RoHS compliance status and higher inventory availability. This ensures regulatory compliance and supply chain reliability for production quantities.

Q: Are both parts from the same manufacturer?

A: Yes. Both 641436-2 and 3-641436-2 are manufactured by TE Connectivity AMP Connectors and belong to the MTA-156 series.

Q: Can these connectors be used with both discrete and ribbon cable?

A: Yes. Both connectors support discrete or ribbon cable termination via IDC (Insulation Displacement Contact) method at 20 AWG wire gauge.
