TE Connectivity 1-640428-3 Equivalent & Substitute Parts

Part Overview

The TE Connectivity 1-640428-3 is a 13-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 and is classified as obsolete. Due to its obsolete product status and RoHS non-compliance, identification of active equivalent parts is necessary for new designs and ongoing production requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 1-640428-3 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Series: MTA-156
• Connector Type: Receptacle
• Number of Positions: 13
• Pitch: 0.156" (3.96mm)
• Number of Rows: 1
• Contact Type: Female Socket
• Cable Termination: IDC
• Wire Gauge: 22 AWG
• Wire Type: Discrete or Ribbon Cable
• Mounting Type: Free Hanging (In-Line)
• Fastening Type: Locking Ramp
• Features: Closed End
• Contact Finish Thickness: 80.0µin (2.03µm)
• Color: Red

The substitute part 4-640428-3 maintains complete equivalence across all mandatory parameters. The primary differences are contact finish composition (tin versus tin-lead), product status (active versus obsolete), and RoHS compliance status. These differences do not affect mechanical or electrical compatibility for IDC termination applications.

Parameter Comparison

Engineering Selection Recommendations

The 4-640428-3 is the direct substitute for the obsolete 1-640428-3. Selection of the 4-640428-3 is appropriate for the following reasons:

Product Status: The 4-640428-3 maintains active product status, ensuring continued availability and manufacturing support. The 1-640428-3 is classified as obsolete and subject to discontinuation.

Regulatory Compliance: The 4-640428-3 is RoHS compliant, meeting current environmental and regulatory requirements for electronic components. The 1-640428-3 is RoHS non-compliant and does not satisfy modern procurement standards.

Contact Finish: The 4-640428-3 uses tin contact finish in place of tin-lead. Both finishes maintain the specified contact finish thickness of 80.0µin (2.03µm) and are compatible with IDC termination methods for 22 AWG cable.

Mechanical and Electrical Equivalence: All mechanical dimensions, electrical characteristics, and functional parameters remain identical between the two parts, ensuring direct interchangeability in MTA-156 series applications.

Frequently Asked Questions (FAQ)

Q: Can the 4-640428-3 be used as a direct replacement for the 1-640428-3 in existing designs?

A: Yes. The 4-640428-3 is mechanically and electrically equivalent to the 1-640428-3 across all critical parameters including connector type, position count, pitch, contact configuration, and IDC termination method. Direct substitution is supported.

Q: What is the difference between tin-lead and tin contact finishes in this connector series?

A: Both contact finishes maintain the same thickness specification of 80.0µin (2.03µm) and are compatible with IDC termination. The primary difference is material composition. Tin-lead finish is used in the obsolete 1-640428-3, while tin finish is used in the active 4-640428-3. Both finishes support the same electrical and mechanical performance for 22 AWG cable applications.

Q: Why is the 1-640428-3 classified as obsolete?

A: The 1-640428-3 is obsolete due to its RoHS non-compliant status and the availability of the RoHS-compliant 4-640428-3 alternative. TE Connectivity has transitioned the MTA-156 series to RoHS-compliant variants.

Q: Are there packaging differences between the 1-640428-3 and 4-640428-3?

A: The 1-640428-3 packaging is not specified in the available data. The 4-640428-3 is supplied in bulk packaging. Packaging format does not affect connector compatibility or performance.

Q: Is the 4-640428-3 suitable for new product designs?

A: Yes. The 4-640428-3 is an active product with RoHS compliance and is appropriate for new designs requiring 13-position MTA-156 series receptacle connectors with IDC termination for 22 AWG cable.

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

A: Both the 1-640428-3 and 4-640428-3 have a Moisture Sensitivity Level (MSL) of 1, indicating unlimited shelf life without moisture control requirements.
