Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 644040-8 is determined by strict equivalence across the following critical parameters:

• Connector Type & Series: Rectangular receptacle from MTA-100 series
• Position Count & Pitch: 8 positions at 0.100" (2.54mm) spacing
• Contact Configuration: Female socket contacts with gold plating
• Termination Method: IDC-compatible for 26 AWG wire
• Mechanical Interface: Free hanging, in-line and right-angle mounting capability
• Electrical Performance: Closed-end design with locking ramp fastening

The substitute part 3-644040-8 maintains identical electrical and mechanical specifications while differing in product status and compliance certification.

Parameter Comparison

Engineering Selection Recommendations

The 3-644040-8 serves as the direct functional equivalent to the obsolete 644040-8. Both components are manufactured by TE Connectivity and maintain identical electrical and mechanical specifications across all critical parameters including connector type, position count, pitch, contact configuration, and termination method.

The primary distinction between these parts is product lifecycle status and regulatory compliance. The 644040-8 is classified as obsolete and does not meet RoHS compliance requirements. The 3-644040-8 is an active product with RoHS compliance certification, making it the appropriate selection for new designs and ongoing procurement where regulatory compliance is required.

Both parts share identical moisture sensitivity levels, export classifications, and tariff codes, indicating equivalent handling and logistics requirements.

Frequently Asked Questions (FAQ)

Q: Can the 3-644040-8 be used as a direct replacement for the 644040-8 in existing assemblies?

A: Yes. The 3-644040-8 maintains identical electrical and mechanical specifications. Both connectors are 8-position rectangular receptacles with 0.100" pitch, IDC termination for 26 AWG wire, and gold-plated female socket contacts. Physical dimensions, mounting interfaces, and functional performance are equivalent.

Q: What is the difference between these two part numbers?

A: The 644040-8 is obsolete and RoHS non-compliant. The 3-644040-8 is an active product with RoHS compliance certification. All other specifications, including connector type, position count, pitch, contact finish, and termination method, are identical.

Q: Are there packaging differences between these parts?

A: The 644040-8 packaging specification is not defined in the available data. The 3-644040-8 is supplied in bulk packaging. Confirm packaging requirements with your procurement specifications.

Q: Does the RoHS compliance difference affect electrical performance?

A: No. RoHS compliance relates to material composition and environmental regulations, not electrical or mechanical performance. Both parts deliver identical functional characteristics.

Q: Can these connectors be used with both discrete and ribbon cable?

A: Yes. Both the 644040-8 and 3-644040-8 support discrete or ribbon cable configurations with 26 AWG wire through IDC termination.

Q: What mounting options are available?

A: Both connectors support free hanging mounting in in-line and right-angle orientations with locking ramp fastening.
