TE Connectivity 640430-6 Rectangular Connector Equivalent & Substitute Parts

Part Overview

The TE Connectivity 640430-6 is a 6-position rectangular receptacle connector from the MTA-156 series, designed for IDC (Insulation Displacement Contact) termination with 26 AWG discrete or ribbon cable. This connector features tin-lead contact finish, a closed-end design, and free-hanging in-line mounting with locking ramp fastening. The part is currently active in production with 942 pieces in stock.

Substitute parts are identified when equivalent electrical and mechanical parameters are maintained across connector specifications. Identifying alternative part numbers is necessary to accommodate inventory availability, packaging requirements, compliance certifications, and manufacturing sourcing flexibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TE Connectivity 640430-6 is determined by strict equivalence across the following critical parameters:

Electrical Compatibility Parameters:

• Connector type (Receptacle)
• Contact type (Female Socket)
• Number of positions (6)
• Pitch spacing (0.156" / 3.96mm)
• Cable termination method (IDC)
• Wire gauge compatibility (26 AWG)
• Wire type support (Discrete or Ribbon Cable)

Mechanical Compatibility Parameters:

• Number of rows (1)
• Mounting type (Free Hanging In-Line)
• Fastening type (Locking Ramp)
• Closed-end design
• Contact finish thickness (80.0µin / 2.03µm)
• Color (Blue)
• Series designation (MTA-156)

Environmental Parameters:

• Moisture Sensitivity Level (MSL 1 - Unlimited)

The substitute part 3-640430-6 maintains all electrical and mechanical parameters identical to the main part. Differences exist only in contact finish material (tin versus tin-lead), packaging configuration (bulk versus standard), and regulatory compliance status.

Parameter Comparison

Engineering Selection Recommendations

Part 640430-6 (Main Part):

• RoHS non-compliant status applies to applications without RoHS regulatory requirements
• Tin-lead contact finish provides established performance characteristics in legacy systems
• Standard packaging configuration suitable for standard procurement workflows
• Lower inventory availability (942 pieces)

Part 3-640430-6 (Substitute):

• ROHS3 compliant status required for applications subject to RoHS Directive 2011/65/EU
• Tin contact finish meets equivalent electrical and mechanical performance specifications
• Bulk packaging configuration suitable for high-volume manufacturing operations
• Higher inventory availability (4154 pieces) supports extended production runs
• Identical electrical and mechanical parameters ensure direct functional equivalence

Selection between these parts is determined by regulatory compliance requirements and packaging needs. Both parts maintain identical connector functionality, pitch spacing, termination method, and wire gauge compatibility.

Frequently Asked Questions (FAQ)

Q: Can part 3-640430-6 be used as a direct replacement for 640430-6 in all applications?

A: Part 3-640430-6 maintains identical electrical and mechanical parameters including connector type, position count, pitch spacing, mounting configuration, and IDC termination method. The primary differences are contact finish material (tin versus tin-lead) and RoHS compliance status. Substitution is valid where these differences do not conflict with application requirements or regulatory mandates.

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

A: Both finishes are provided at 80.0µin (2.03µm) thickness. The contact finish material difference does not affect the electrical or mechanical compatibility of the connector within the MTA-156 series specifications.

Q: Does the bulk packaging of part 3-640430-6 affect connector performance?

A: Packaging configuration does not affect connector electrical or mechanical performance. Bulk packaging is a logistics and procurement consideration only. Both parts are identical in functional design and specifications.

Q: Why is inventory availability different between these parts?

A: Inventory levels reflect current stock positions and do not indicate performance differences. Part 3-640430-6 has higher availability (4154 pieces versus 942 pieces) and may be selected for applications requiring extended lead times or high-volume procurement.

Q: Are both parts suitable for IDC termination with 26 AWG ribbon cable?

A: Both parts support IDC termination with 26 AWG discrete or ribbon cable. The closed-end design, locking ramp fastening, and contact specifications are identical across both part numbers.

Q: What does RoHS3 compliance mean for part 3-640430-6?

A: ROHS3 compliance indicates conformance to RoHS Directive 2011/65/EU requirements. This status is required for applications subject to European Union regulatory frameworks. Part 640430-6 is RoHS non-compliant and suitable for applications without such regulatory requirements.

Q: Can these connectors be used interchangeably in the same assembly?

A: Yes, within the same assembly, both parts maintain identical mechanical mounting, electrical contact specifications, and functional performance. Selection between them is determined by regulatory compliance needs and packaging requirements only.
