Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 644020-5 is determined by strict equivalence across the following critical parameters:

Electrical Compatibility Parameters:

• Connector type (Receptacle)
• Contact type (Female Socket)
• Number of positions (5)
• Pitch (0.100" / 2.54mm)
• Number of rows (1)
• Cable termination method (IDC)
• Wire gauge compatibility (24 AWG)
• Contact finish (Gold)
• Contact finish thickness (30.0µin / 0.76µm)

Mechanical Compatibility Parameters:

• Mounting type (Free Hanging In-Line, Right Angle)
• Fastening type (Locking Ramp)
• Features (Closed End)
• Color (White)

Series Designation:

• MTA-100 series

The substitute part 3-644020-5 maintains full equivalence across all specified parameters while offering improved product status and compliance characteristics.

Parameter Comparison

Engineering Selection Recommendations

The substitute part 3-644020-5 is the direct functional equivalent of the obsolete 644020-5. Both parts are manufactured by TE Connectivity AMP Connectors and belong to the MTA-100 series. The parts are electrically and mechanically identical across all specified parameters.

Key Differentiators:

The primary distinction between the main part and its substitute is product status and regulatory compliance. The 644020-5 is classified as obsolete and carries RoHS non-compliant status. The 3-644020-5 is an active product with RoHS compliance certification, making it suitable for new designs and systems requiring regulatory adherence.

Inventory Availability:

The 3-644020-5 substitute maintains significantly higher inventory availability (5,483 pieces) compared to the obsolete 644020-5 (900 pieces), supporting consistent procurement for production and maintenance applications.

Packaging Consideration:

The substitute part is supplied in bulk packaging, whereas the main part packaging specification is not defined. This distinction may affect procurement workflows and storage requirements.

Frequently Asked Questions (FAQ)

Q: Are the 644020-5 and 3-644020-5 electrically interchangeable?

A: Yes. Both parts are 5-position receptacle connectors with identical electrical specifications: female socket contacts, gold plating at 30.0µin thickness, 24 AWG wire gauge compatibility, and IDC termination method. They operate within the same electrical parameters and are fully interchangeable in circuit applications.

Q: Are the 644020-5 and 3-644020-5 mechanically interchangeable?

A: Yes. Both connectors share identical mechanical specifications: 0.100" (2.54mm) pitch, single-row configuration, free-hanging in-line and right-angle mounting options, locking ramp fastening, and closed-end design. Physical dimensions and mounting interfaces are equivalent.

Q: Why should I use the 3-644020-5 instead of the 644020-5?

A: The 3-644020-5 is an active product with RoHS compliance certification, whereas the 644020-5 is obsolete and RoHS non-compliant. For new designs, system upgrades, and regulatory compliance requirements, the 3-644020-5 is the appropriate selection. Additionally, the substitute part offers superior inventory availability.

Q: What is the difference in packaging between these parts?

A: The 644020-5 packaging specification is not defined in the product data. The 3-644020-5 is supplied in bulk packaging. Confirm packaging requirements with your procurement specifications before ordering.

Q: Can I use the 3-644020-5 in existing systems designed for the 644020-5?

A: Yes. The 3-644020-5 maintains full electrical and mechanical equivalence with the 644020-5 across all specified parameters. It is suitable for replacement in existing systems without design modification.

Q: Are there any compliance differences between these parts?

A: The 644020-5 is RoHS non-compliant, while the 3-644020-5 is RoHS compliant. Both parts carry identical ECCN (EAR99) and HTSUS (8536.69.8000) classifications. If your application requires RoHS compliance, the 3-644020-5 is the required selection.

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

A: Both the 644020-5 and 3-644020-5 carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions for storage or handling.
