TE Connectivity 641653-3 Rectangular Connector Equivalent & Substitute Parts

Part Overview

The TE Connectivity 641653-3 is a 3-position rectangular receptacle connector from the MTA-100 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 an active product with unlimited moisture sensitivity rating. The connector uses a locking ramp fastening mechanism and supports free hanging in-line or right-angle mounting configurations.

Substitute parts are identified to address specific application requirements, including RoHS compliance status and contact finish variations, while maintaining electrical and mechanical compatibility within the MTA-100 series.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TE Connectivity 641653-3 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Connector type (Receptacle)
• Number of positions (3)
• Pitch specification (0.100" / 2.54mm)
• Number of rows (1)
• Contact type (Female Socket)
• Wire gauge (22 AWG)
• Cable termination method (IDC)
• Mounting type (Free Hanging In-Line, Right Angle)
• Fastening type (Locking Ramp)
• Contact finish thickness (80.0µin / 2.03µm)
• Series designation (MTA-100)

Variable Parameters Allowing Substitution:

• Contact finish material (Tin-Lead vs. Tin)
• RoHS compliance status
• Packaging configuration

The identified substitute maintains all mandatory parameters while offering alternative contact finish and compliance certifications suitable for different regulatory and environmental requirements.

Parameter Comparison

Engineering Selection Recommendations

641653-3 (Tin-Lead Contact Finish): Use this part number for applications where RoHS non-compliance is acceptable or where legacy system compatibility requires tin-lead contact finish. This configuration is suitable for non-regulated environments or systems with established tin-lead specifications.

3-641653-3 (Tin Contact Finish, RoHS Compliant): Select this substitute part for applications requiring RoHS compliance certification. The tin contact finish with equivalent thickness (80.0µin / 2.03µm) provides electrical and mechanical performance parity with the main part while meeting regulatory requirements for restricted substance elimination. This part is the preferred selection for new designs and regulated industries.

Both parts maintain identical electrical and mechanical specifications within the MTA-100 series, including connector geometry, contact configuration, termination method, and mounting flexibility. The choice between these parts is determined by regulatory compliance requirements and contact finish material specifications for the target application.

Frequently Asked Questions (FAQ)

Q: Can 3-641653-3 be used as a direct replacement for 641653-3 in existing assemblies?

A: Yes. Both parts are mechanically and electrically equivalent within the MTA-100 series. They share identical pitch (0.100"), position count (3), contact type (female socket), wire gauge (22 AWG), and termination method (IDC). The primary difference is contact finish material and RoHS compliance status. Compatibility depends on application-specific requirements for these parameters.

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

A: Both contact finishes are applied at equivalent thickness (80.0µin / 2.03µm). The selection between tin-lead and tin is determined by regulatory compliance requirements and system specifications. Tin-lead (641653-3) is used in non-RoHS applications, while tin (3-641653-3) is specified for RoHS-compliant designs.

Q: Are these connectors suitable for ribbon cable applications?

A: Yes. Both parts support discrete or ribbon cable termination via IDC (Insulation Displacement Contact) method at 22 AWG wire gauge. The IDC termination mechanism accommodates both cable types within the specified gauge range.

Q: What does the locking ramp fastening type provide?

A: The locking ramp fastening mechanism secures the connector assembly and provides positive engagement. Both the main part and substitute feature this fastening type, ensuring consistent mechanical retention across equivalent configurations.

Q: Can these connectors be mounted in different orientations?

A: Yes. Both parts support free hanging in-line and right-angle mounting configurations, providing flexibility for various PCB layout and cable routing requirements.

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

A: Both parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions. These connectors can be stored and handled without moisture control precautions.

Q: Are there inventory considerations when selecting between these part numbers?

A: The main part (641653-3) has 1076 pieces in stock, while the substitute (3-641653-3) has 2507 pieces available. Packaging differs: 641653-3 uses standard packaging while 3-641653-3 is supplied in bulk configuration.
