TE Connectivity 1-640428-6 Equivalent & Substitute Parts

Part Overview

The TE Connectivity 1-640428-6 is a 16-position rectangular receptacle connector from the MTA-156 series, designed for IDC (Insulation Displacement Contact) termination with 22 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 Active in product status with RoHS compliance and unlimited moisture sensitivity rating.

Substitute parts are identified when equivalent electrical and mechanical parameters are maintained across connector specifications, allowing for component interchangeability in applications where the primary part becomes unavailable or when alternative packaging or compliance requirements are necessary.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1-640428-6 is determined by strict equivalence across the following critical parameters:

Electrical Compatibility Parameters:

• Connector type (Receptacle)
• Number of positions (16)
• Contact type (Female Socket)
• Wire gauge (22 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)
• Contact finish thickness (80.0µin / 2.03µm)
• Closed-end design

Compliance Parameters:

• RoHS status (RoHS Compliant or ROHS3 Compliant)
• Product status (Active)
• Series designation (MTA-156)

The substitute part 4-640428-6 maintains all electrical and mechanical parameters while differing in contact finish composition (Tin versus Tin-Lead) and packaging configuration (Bulk versus standard packaging). These differences do not affect functional interchangeability in IDC termination applications.

Parameter Comparison

Engineering Selection Recommendations

Both the 1-640428-6 and 4-640428-6 are Active products from TE Connectivity's MTA-156 rectangular connector series and maintain full functional equivalence for IDC termination applications with 22 AWG cable.

Primary Part Selection (1-640428-6): The 1-640428-6 features tin-lead contact finish and is designated as REACH Affected. This part is suitable for applications where tin-lead plating specifications are explicitly required or where existing designs have been validated with this contact finish composition.

Substitute Part Selection (4-640428-6): The 4-640428-6 features tin contact finish and is designated as REACH Unaffected, offering compliance advantages in supply chains subject to REACH regulations. The part is supplied in bulk packaging and maintains identical electrical and mechanical specifications. This substitute is functionally interchangeable for new designs or applications where tin contact finish meets performance requirements.

Both parts maintain RoHS compliance (RoHS Compliant and ROHS3 Compliant respectively), unlimited moisture sensitivity rating (MSL 1), and identical connector geometry, pitch, and termination methodology. Selection between these parts depends on contact finish requirements, REACH compliance obligations, and packaging preferences rather than functional performance differences.

Frequently Asked Questions (FAQ)

Q: Are the 1-640428-6 and 4-640428-6 mechanically interchangeable?

A: Yes. Both connectors maintain identical pitch (0.156"), number of positions (16), mounting type (free-hanging in-line), fastening type (locking ramp), and contact finish thickness (80.0µin). They are mechanically interchangeable in all applications designed for MTA-156 16-position receptacle connectors.

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

A: The 1-640428-6 features tin-lead contact finish, while the 4-640428-6 features tin contact finish. Both maintain the same contact finish thickness of 80.0µin (2.03µm). The contact finish composition affects REACH compliance status and may influence solder joint characteristics in specific applications, but both finishes are applied at equivalent thickness.

Q: Does the bulk packaging of the 4-640428-6 affect connector performance?

A: No. Packaging configuration (standard versus bulk) does not affect electrical or mechanical performance. Packaging differences relate to order quantity and handling logistics only. The connector specifications, termination method, and electrical characteristics remain identical.

Q: Can I use the 4-640428-6 as a direct replacement for the 1-640428-6 in existing designs?

A: The 4-640428-6 is functionally equivalent for IDC termination with 22 AWG cable. However, if the original design specification explicitly requires tin-lead contact finish or REACH Affected status, design documentation should be reviewed. For applications where contact finish composition is not specified, the 4-640428-6 provides direct substitution.

Q: What does REACH Affected versus REACH Unaffected mean for these connectors?

A: REACH Affected (1-640428-6) indicates the part may contain substances of concern under REACH regulations. REACH Unaffected (4-640428-6) indicates the part does not contain such substances. Selection depends on supply chain requirements and regulatory obligations in the end-use market.

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

A: Yes. Both the 1-640428-6 and 4-640428-6 support IDC termination for discrete or ribbon cable at 22 AWG wire gauge. The closed-end design and locking ramp fastening are identical across both parts.

Q: What is the inventory status for these parts?

A: The 1-640428-6 has 823 pieces in stock, and the 4-640428-6 has 1072 pieces in stock as new original inventory. Availability should be confirmed with the supplier for current requirements.
