TE Connectivity 640604-5 Rectangular Connector Equivalent & Substitute Parts

Part Overview

The TE Connectivity 640604-5 is a 5-position rectangular receptacle 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 classified as an active product with unlimited moisture sensitivity rating.

Identification of equivalent and substitute parts is necessary to address component availability, packaging requirements, compliance certifications, and manufacturing specifications that may vary across production batches or procurement channels.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 640604-5 is determined by strict equivalence across the following critical parameters:

• Connector Configuration: Receptacle type, 5-position, single-row layout with 0.156" pitch
• Electrical Interface: Female socket contacts with IDC termination method
• Cable Compatibility: 18 AWG wire gauge for discrete or ribbon cable
• Physical Mounting: Free hanging in-line configuration
• Environmental Rating: MSL 1 (unlimited moisture sensitivity)
• Series Designation: MTA-156 series compatibility

The substitute part 3-640604-5 maintains identical mechanical and electrical specifications while differing in contact finish composition (tin versus tin-lead) and RoHS compliance status. Both parts share the same base product number (640604) and are manufactured by TE Connectivity AMP Connectors.

Parameter Comparison

Engineering Selection Recommendations

640604-5 (Tin-Lead Contact Finish)

Select this part number when:

• RoHS non-compliant applications are acceptable
• Tin-lead contact finish is specified in design documentation
• Legacy system compatibility is required
• Existing inventory or procurement contracts reference this specific part number

3-640604-5 (Tin Contact Finish)

Select this part number when:

• RoHS compliance is required for the end application
• Tin contact finish meets design specifications
• New designs or updated procurement standards mandate RoHS-compliant components
• Bulk packaging is preferred for manufacturing operations

Both parts are active products manufactured by TE Connectivity AMP Connectors and maintain identical mechanical, electrical, and environmental specifications within the MTA-156 series. The primary differentiation is contact finish composition and regulatory compliance status.

Frequently Asked Questions (FAQ)

Q: Are 640604-5 and 3-640604-5 mechanically interchangeable?

A: Yes. Both connectors are 5-position receptacles with identical pitch (0.156"), mounting configuration (free hanging in-line), and contact geometry. They are mechanically interchangeable in all applications.

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

A: The 640604-5 features tin-lead contact finish, while the 3-640604-5 features tin contact finish. Both maintain the same contact finish thickness of 80.0µin (2.03µm). The tin-lead variant is RoHS non-compliant; the tin variant is RoHS compliant.

Q: Can I substitute 3-640604-5 for 640604-5 in an existing design?

A: Substitution is permissible if the design does not explicitly require tin-lead contact finish and if RoHS compliance is acceptable or required. Verify design documentation and regulatory requirements before substitution.

Q: What packaging differences exist between these parts?

A: The 640604-5 is supplied in standard packaging (not specified in documentation). The 3-640604-5 is supplied in bulk packaging. Confirm packaging requirements with procurement specifications.

Q: Are both parts suitable for 18 AWG ribbon cable termination?

A: Yes. Both connectors support IDC termination for 18 AWG discrete or ribbon cable. Wire gauge compatibility is identical across both part numbers.

Q: What is the MSL rating for these connectors?

A: Both parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity limitations during storage or handling.

Q: Are there any REACH or export restrictions on these parts?

A: The 640604-5 is REACH Affected. The 3-640604-5 has Vendor Undefined REACH status. Both parts carry ECCN EAR99 classification. Verify compliance requirements with your procurement and legal departments for specific applications and destinations.
