Key Parameters

Substitute Part Grouping Explanation

Substitution between the main part 640601-4 and its equivalent 3-640601-4 is based on matching the following critical parameters:

Electrical Compatibility Parameters:

• Connector type: Receptacle
• Number of positions: 4
• Contact type: Female socket
• Pitch: 0.156" (3.96mm)
• Wire gauge: 22 AWG
• Cable termination: IDC

Mechanical Compatibility Parameters:

• Mounting type: Free Hanging (In-Line)
• Fastening type: Locking Ramp
• Series designation: MTA-156
• Number of rows: 1

Regulatory and Finish Parameters:

• Contact finish thickness: 80.0µin (2.03µm)
• Color: Red
• ECCN: EAR99
• HTSUS: 8536.69.8000

The primary distinction between the main part and substitute is the contact finish specification (tin-lead versus tin) and RoHS compliance status. Both parts share identical electrical and mechanical interfaces, enabling direct substitution in applications where the finish and compliance requirements align.

Parameter Comparison

Engineering Selection Recommendations

640601-4 Selection Criteria:

• Applications requiring tin-lead contact finish
• Environments where RoHS non-compliance is acceptable or not regulated
• Legacy system designs or specifications that explicitly call for tin-lead termination

3-640601-4 Selection Criteria:

• Applications subject to RoHS compliance requirements
• New product designs requiring lead-free contact materials
• Regulatory environments mandating RoHS-compliant components
• Higher inventory availability (2728 units in stock versus 1062 units)

Both parts maintain identical electrical performance, mechanical interface, and physical dimensions. The selection between them is determined by regulatory compliance requirements and contact finish specifications rather than functional capability. The substitute part 3-640601-4 offers RoHS compliance with equivalent performance characteristics.

Frequently Asked Questions (FAQ)

Q: Can 3-640601-4 be used as a direct replacement for 640601-4?

A: Yes, 3-640601-4 functions as a direct electrical and mechanical substitute for 640601-4. Both connectors share identical pitch, position count, mounting configuration, and IDC termination method. The primary differences are contact finish (tin versus tin-lead) and RoHS compliance status. Selection depends on regulatory requirements and application specifications.

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

A: The main part 640601-4 features a tin-lead contact finish, while the substitute 3-640601-4 uses tin. Both finishes provide 80.0µin (2.03µm) thickness. Tin-lead finishes are found in legacy designs, while tin finishes comply with RoHS regulations and are standard in modern applications.

Q: Are these connectors compatible with ribbon cable?

A: Yes, both 640601-4 and 3-640601-4 support discrete or ribbon cable termination via IDC (Insulation Displacement Contact) method. The 22 AWG wire gauge specification applies to both cable types.

Q: What does the MTA-156 series designation indicate?

A: MTA-156 is the TE Connectivity series designation for this connector family. The "156" refers to the 0.156" (3.96mm) pitch specification. Both the main part and substitute belong to this same series, ensuring mechanical and electrical compatibility.

Q: Does packaging type affect connector performance?

A: No. The main part 640601-4 is supplied in standard packaging, while 3-640601-4 is supplied in bulk packaging. Packaging type does not affect electrical or mechanical performance. Selection between packaging options depends on inventory management and procurement requirements.

Q: What is the Moisture Sensitivity Level (MSL) rating?

A: Both connectors carry an MSL rating of 1 (Unlimited), indicating no moisture sensitivity restrictions. These connectors can be stored and handled without special humidity control measures.

Q: Are both parts currently in production?

A: Yes, both 640601-4 and 3-640601-4 are active products in TE Connectivity's current product line. Both are available in stock with substantial inventory levels.
