TE Connectivity 640430-2 Rectangular Connector Equivalent & Substitute Parts

Part Overview

The TE Connectivity 640430-2 is a 2-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 1044 units in stock.

Substitute parts are identified when equivalent electrical and mechanical parameters are maintained across connector specifications. Alternative part numbers may be necessary due to packaging availability, compliance status differences, or inventory requirements while preserving functional compatibility in the application circuit.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TE Connectivity 640430-2 is determined by strict equivalence across the following critical parameters:

Electrical Compatibility Parameters:

• Connector type (Receptacle)
• Number of positions (2)
• Contact type (Female Socket)
• Wire gauge (26 AWG)
• Cable termination method (IDC)

Mechanical Compatibility Parameters:

• Pitch (0.156" / 3.96mm)
• Number of rows (1)
• Mounting type (Free Hanging In-Line)
• Fastening type (Locking Ramp)
• Features (Closed End)
• Contact finish thickness (80.0µin / 2.03µm)

Environmental Parameters:

• Moisture Sensitivity Level (1 - Unlimited)
• Series designation (MTA-156)

The substitute part 3-640430-2 maintains all electrical and mechanical parameters identical to the main part. Differences exist only in contact finish material (tin versus tin-lead), packaging format (bulk versus standard), and regulatory compliance status. These differences do not affect functional interchangeability in the application circuit.

Parameter Comparison

Engineering Selection Recommendations

640430-2 Selection Criteria: The 640430-2 is appropriate for applications where tin-lead contact finish is specified or required by design documentation. This part is active in production and maintains RoHS non-compliant status. Current inventory of 1044 units supports immediate availability for production requirements.

3-640430-2 Selection Criteria: The 3-640430-2 is appropriate for applications requiring RoHS compliance or where tin contact finish is acceptable. This part is active in production with higher inventory availability (2816 units), supporting extended production runs. The bulk packaging format accommodates high-volume assembly operations.

Functional Interchangeability: Both parts maintain identical electrical and mechanical specifications across all critical parameters including connector type, position count, pitch, contact type, termination method, wire gauge, mounting configuration, and fastening mechanism. The contact finish difference (tin-lead versus tin) does not affect functional compatibility in the application circuit. Selection between these parts is determined by compliance requirements and packaging needs rather than electrical or mechanical constraints.

Frequently Asked Questions (FAQ)

Q: Can 3-640430-2 be used as a direct replacement for 640430-2 in existing designs?

A: Yes. Both parts are functionally equivalent across all electrical and mechanical parameters. The primary differences are contact finish material (tin versus tin-lead) and RoHS compliance status. Selection depends on design compliance requirements and packaging format needs.

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

A: The contact finish material differs between the two parts. The 640430-2 uses tin-lead finish while the 3-640430-2 uses tin finish. Both maintain identical contact finish thickness of 80.0µin (2.03µm). The choice between these finishes is determined by application requirements and regulatory compliance specifications.

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

A: Yes. Both the 640430-2 and 3-640430-2 support discrete or ribbon cable termination via IDC (Insulation Displacement Contact) method at 26 AWG wire gauge.

Q: What does the packaging difference mean for component selection?

A: The 640430-2 is supplied in standard packaging while the 3-640430-2 is supplied in bulk packaging. Bulk packaging is typically used for high-volume assembly operations and offers higher unit quantities per package. Standard packaging is used for lower-volume or mixed-component orders.

Q: Why would I choose the 3-640430-2 over the 640430-2?

A: The 3-640430-2 is selected when RoHS compliance is required by design specification or regulatory requirement. It also provides higher inventory availability (2816 units versus 1044 units) and bulk packaging format for high-volume production. Functionally, both parts are equivalent.

Q: Are both parts currently in active production?

A: Yes. Both the 640430-2 and 3-640430-2 maintain active product status with current inventory in stock.

Q: What is the moisture sensitivity level for these connectors?

A: Both parts have Moisture Sensitivity Level (MSL) of 1, which indicates unlimited shelf life without moisture control requirements.
