Substitute Part Grouping Explanation

Substitution between the main part (1-640428-2) and the identified equivalent (4-640428-2) is based on the following criteria:

Electrical Compatibility Parameters:

• Identical connector type (Receptacle)
• Identical number of positions (12)
• Identical pitch (0.156" / 3.96mm)
• Identical contact type (Female Socket)
• Identical cable termination method (IDC)
• Identical wire gauge (22 AWG)
• Identical contact finish thickness (80.0µin / 2.03µm)

Mechanical Compatibility Parameters:

• Identical mounting type (Free Hanging, In-Line)
• Identical fastening type (Locking Ramp)
• Identical number of rows (1)
• Identical features (Closed End)
• Identical color (Red)
• Identical series designation (MTA-156)

Differentiating Parameters:

• Contact finish material: Tin-Lead (1-640428-2) versus Tin (4-640428-2)
• RoHS compliance status: Non-compliant (1-640428-2) versus ROHS3 Compliant (4-640428-2)
• Packaging: Standard (1-640428-2) versus Bulk (4-640428-2)
• REACH status: REACH Affected (1-640428-2) versus Vendor Undefined (4-640428-2)

Parameter Comparison

Engineering Selection Recommendations

Selection Criteria Based on Regulatory and Compliance Requirements:

The 4-640428-2 substitute part is functionally equivalent to the 1-640428-2 across all electrical and mechanical parameters. The primary distinction lies in regulatory compliance status.

For applications requiring RoHS3 compliance: The 4-640428-2 is the appropriate selection, as it meets ROHS3 compliance requirements. This part is suitable for new designs and applications subject to RoHS directives.

For applications with legacy or non-RoHS requirements: The 1-640428-2 remains available and maintains full electrical and mechanical compatibility. This part is appropriate for maintenance, repair, and retrofit applications where RoHS compliance is not mandated.

Contact Finish Consideration: The 1-640428-2 features tin-lead contact finish, while the 4-640428-2 features tin contact finish. Both maintain identical contact finish thickness (80.0µin / 2.03µm) and are electrically equivalent for IDC termination applications.

Packaging Consideration: The 4-640428-2 is supplied in bulk packaging with higher inventory availability (1202 units) compared to the 1-640428-2 (818 units), which may influence procurement decisions for high-volume applications.

Both parts are active products from TE Connectivity AMP Connectors and are suitable for direct substitution in MTA-156 series 12-position IDC receptacle connector applications.

Frequently Asked Questions (FAQ)

Q: Can the 4-640428-2 be used as a direct replacement for the 1-640428-2?

A: Yes. The 4-640428-2 is electrically and mechanically equivalent to the 1-640428-2. Both connectors share identical specifications for connector type, position count, pitch, contact type, termination method, wire gauge, mounting configuration, and fastening mechanism. The primary differences are RoHS compliance status and contact finish material composition.

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

A: The 1-640428-2 features tin-lead contact finish, while the 4-640428-2 features tin contact finish. Both maintain the same contact finish thickness of 80.0µin (2.03µm). The contact finish material does not affect electrical performance or mechanical compatibility in IDC termination applications.

Q: Which part should be selected for new product designs?

A: For new product designs subject to RoHS directives, the 4-640428-2 is the appropriate selection due to its ROHS3 compliance status. For applications without RoHS requirements, either part is suitable based on availability and procurement preferences.

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

A: Yes. Both the 1-640428-2 and 4-640428-2 support discrete or ribbon cable termination via IDC (Insulation Displacement Contact) method at 22 AWG wire gauge.

Q: What is the pitch specification, and why is it important for substitution?

A: Both connectors feature a 0.156" (3.96mm) pitch, which defines the center-to-center spacing between contact positions. Identical pitch is a critical requirement for mechanical and electrical compatibility in connector substitution.

Q: Do these connectors require any special handling or storage conditions?

A: Both connectors are rated at MSL (Moisture Sensitivity Level) 1, indicating unlimited shelf life without moisture control requirements.

Q: What is the difference in packaging between these two parts?

A: The 1-640428-2 is supplied in standard packaging, while the 4-640428-2 is supplied in bulk packaging. Bulk packaging is typically used for high-volume procurement and may offer cost advantages for large-scale applications.

Q: Are both parts currently in production?

A: Yes. Both the 1-640428-2 and 4-640428-2 are classified as active products and are available from TE Connectivity AMP Connectors.
