TE Connectivity 644702-5 Rectangular Connector Equivalent & Substitute Parts

Part Overview

The TE Connectivity 644702-5 is a 5-position rectangular receptacle connector from the MTA-100 series, designed for IDC (Insulation Displacement Contact) termination with 22 AWG wire. This connector features gold-plated female socket contacts, a 0.100" pitch, and supports both discrete and ribbon cable configurations with a locking ramp fastening mechanism.

The 644702-5 carries an obsolete product status. Identifying equivalent and substitute parts is necessary to ensure continued availability for maintenance, repair, and new production applications where this connector type is specified.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 644702-5 is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Connector type (Receptacle)
• Contact type (Female Socket)
• Number of positions (5)
• Contact pitch (0.100" / 2.54mm)
• Wire gauge compatibility (22 AWG)
• Contact finish specification (Gold, 30.0µin thickness)

Mechanical Parameters:

• Cable termination method (IDC)
• Mounting configuration (Free Hanging, In-Line, Right Angle)
• Fastening mechanism (Locking Ramp)
• Series designation (MTA-100)

Environmental & Compliance Parameters:

• Moisture Sensitivity Level (MSL 1 - Unlimited)
• ECCN classification (EAR99)
• HTSUS code (8536.69.8000)

Substitute parts must match all electrical and mechanical parameters without exception. Packaging differences and product status variations do not affect functional interchangeability.

Parameter Comparison

Engineering Selection Recommendations

The 3-644702-5 is a direct functional equivalent to the 644702-5 across all electrical and mechanical specifications. Both connectors are manufactured by TE Connectivity and share identical MTA-100 series characteristics, contact configurations, and termination methods.

Product Status Consideration: The 644702-5 is classified as obsolete, while the 3-644702-5 maintains active product status. For new designs, maintenance applications, and long-term supply chain planning, the 3-644702-5 is the appropriate selection due to its active availability and continued manufacturer support.

Compliance Consideration: The 3-644702-5 is ROHS3 compliant, whereas the 644702-5 is RoHS non-compliant. Applications subject to RoHS regulations or requiring compliance documentation should specify the 3-644702-5. For legacy systems or applications without RoHS requirements, both parts remain functionally equivalent.

Packaging Consideration: The 3-644702-5 is supplied in bulk packaging. The original 644702-5 packaging specification is not provided. Packaging differences do not affect connector performance or interchangeability in the application.

Frequently Asked Questions (FAQ)

Q: Can the 3-644702-5 be used as a direct replacement for the 644702-5?

A: Yes. The 3-644702-5 is functionally equivalent to the 644702-5. All electrical and mechanical parameters are identical, including connector type, contact configuration, pitch, wire gauge, termination method, and mounting specifications. The connectors are interchangeable in applications.

Q: What is the difference between the 644702-5 and 3-644702-5?

A: The primary differences are product status and regulatory compliance. The 644702-5 is obsolete and RoHS non-compliant. The 3-644702-5 is an active product with ROHS3 compliance. Functionally, both connectors are identical.

Q: Why is the 644702-5 listed as obsolete?

A: The 644702-5 has been superseded by the 3-644702-5 in the manufacturer's product line. The 3-644702-5 provides the same functionality with updated compliance certifications and continued availability.

Q: Are there any compatibility issues when substituting the 3-644702-5 for the 644702-5?

A: No compatibility issues exist. Both connectors share identical specifications for pitch, contact type, wire gauge, termination method, and mounting configuration. They are mechanically and electrically interchangeable.

Q: Does the bulk packaging of the 3-644702-5 affect its performance?

A: No. Packaging type does not affect connector performance, electrical characteristics, or mechanical function. Bulk packaging is a supply and handling consideration only.

Q: Which part should be specified for new designs?

A: The 3-644702-5 should be specified for new designs. It is an active product with current manufacturer support and ROHS3 compliance, ensuring long-term availability and regulatory alignment.

Q: Can the 644702-5 be used in RoHS-regulated applications?

A: The 644702-5 is RoHS non-compliant and should not be used in applications requiring RoHS compliance. The 3-644702-5 is ROHS3 compliant and is the appropriate choice for regulated applications.

Q: What wire gauges are compatible with these connectors?

A: Both the 644702-5 and 3-644702-5 are rated for 22 AWG wire. They support both discrete and ribbon cable configurations with IDC termination.

Q: Is the MTA-100 series still in production?

A: The 3-644702-5 is an active MTA-100 series product. The 644702-5 is obsolete. Current production and availability are supported through the 3-644702-5 variant.
