Key Parameters

Substitute Part Grouping Explanation

Substitution between the main part 1-640433-6 and the equivalent part 4-640433-6 is based on strict alignment of the following critical parameters:

Electrical Compatibility Parameters:

• Connector type (Receptacle)
• Number of positions (16)
• Contact type (Female Socket)
• Pitch (0.156" / 3.96mm)
• Cable termination method (IDC)
• Wire gauge (22 AWG)
• Contact finish thickness (80.0µin / 2.03µm)

Mechanical Compatibility Parameters:

• Number of rows (1)
• Mounting type (Free Hanging, In-Line)
• Closed-end design
• Series designation (MTA-156)

Differentiating Factor: The primary distinction between these parts is the contact finish specification: 1-640433-6 uses tin-lead finish, while 4-640433-6 uses tin finish. Both finishes meet the same thickness requirement of 80.0µin (2.03µm). The secondary distinction is packaging format and RoHS compliance status.

Parameter Comparison

Engineering Selection Recommendations

For RoHS3 Compliant Applications: Select part 4-640433-6. This part carries ROHS3 compliance certification and is suitable for applications subject to RoHS Directive 2011/65/EU requirements. The tin contact finish eliminates lead content while maintaining the specified contact finish thickness of 80.0µin (2.03µm).

For Legacy or Non-Regulated Applications: Part 1-640433-6 remains available with tin-lead contact finish. This part is suitable for applications without RoHS compliance requirements and maintains full electrical and mechanical compatibility with the MTA-156 series specifications.

Compliance Considerations: Both parts are classified under ECCN EAR99 and HTSUS 8536.69.8000. The REACH status differs: 1-640433-6 is REACH Affected, while 4-640433-6 shows Vendor Undefined status. Verify REACH compliance requirements with your specific application and regional regulations.

Packaging and Availability: Both parts are supplied as new original stock. Part 1-640433-6 is available in standard packaging with 998 units in inventory. Part 4-640433-6 is supplied in bulk packaging with 864 units in inventory. Selection between these options depends on packaging requirements and supply chain logistics.

Frequently Asked Questions (FAQ)

Q: Are 1-640433-6 and 4-640433-6 electrically interchangeable?

A: Yes. Both parts are 16-position receptacle connectors with identical pitch (0.156"), contact type (female socket), wire gauge (22 AWG), and IDC termination method. The electrical performance is equivalent within the MTA-156 series specifications.

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

A: The main part 1-640433-6 uses tin-lead finish, while the substitute 4-640433-6 uses tin finish. Both finishes meet the same thickness specification of 80.0µin (2.03µm). Tin finish eliminates lead content, making 4-640433-6 suitable for RoHS3 compliant applications.

Q: Can I use 4-640433-6 as a direct replacement for 1-640433-6?

A: Yes, provided your application does not specifically require tin-lead contact finish. The mechanical and electrical parameters are identical. If your design or application documentation specifies tin-lead finish, use the original part 1-640433-6.

Q: What does RoHS3 compliance mean for part 4-640433-6?

A: RoHS3 compliance indicates that part 4-640433-6 conforms to RoHS Directive 2011/65/EU, which restricts the use of certain hazardous substances including lead. This part is suitable for applications subject to RoHS regulations in the European Union and equivalent jurisdictions.

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

A: Yes. Both 1-640433-6 and 4-640433-6 support discrete or ribbon cable termination via IDC (Insulation Displacement Contact) method at 22 AWG wire gauge.

Q: What is the significance of the closed-end feature?

A: The closed-end design prevents accidental contact with the internal connector elements and provides mechanical protection. Both parts incorporate this feature as part of the MTA-156 series standard design.

Q: Do both parts have the same moisture sensitivity level?

A: Yes. Both parts are classified as MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage, handling, or use.

Q: What packaging options are available?

A: Part 1-640433-6 is supplied in standard packaging, while part 4-640433-6 is supplied in bulk packaging. Confirm packaging requirements with your procurement specifications.
