Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 644284-8 is determined by strict equivalence across the following critical parameters:

Electrical Compatibility Parameters:

• Connector type (Receptacle)
• Contact type (Female Socket)
• Number of positions (8)
• Pitch specification (0.156" / 3.96mm)
• Cable termination method (IDC)
• Wire gauge compatibility (18 AWG)
• Contact finish (Gold)

Mechanical Compatibility Parameters:

• Mounting type (Free Hanging In-Line)
• Fastening type (Locking Ramp)
• Features (Closed End, Polarizing Key)
• Series designation (MTA-156)

Regulatory & Compliance Parameters:

• RoHS compliance status
• REACH compliance status
• Moisture Sensitivity Level (MSL)

Parts meeting all electrical and mechanical parameters are classified as direct substitutes. Differences in product status (obsolete versus active) and packaging configuration do not affect functional interchangeability.

Parameter Comparison

Engineering Selection Recommendations

The 3-644284-8 is a direct functional equivalent to the 644284-8 across all electrical and mechanical parameters. Both connectors are identical in connector type, contact configuration, pitch, termination method, and wire gauge specifications.

The primary distinction between these parts is product status and regulatory compliance. The 644284-8 is classified as obsolete and carries RoHS non-compliant status. The 3-644284-8 is an active product with ROHS3 compliance certification.

For new designs and ongoing procurement, the 3-644284-8 is the appropriate selection. This part maintains full functional compatibility while providing current regulatory compliance and active manufacturer support. Both parts share identical moisture sensitivity levels and REACH compliance status, indicating equivalent environmental performance characteristics.

Frequently Asked Questions (FAQ)

Q: Can the 3-644284-8 be used as a direct replacement for the 644284-8?

A: Yes. The 3-644284-8 is functionally equivalent to the 644284-8. Both connectors share identical electrical and mechanical specifications, including 8-position configuration, 0.156" pitch, IDC termination, 18 AWG wire gauge, gold contact finish, and locking ramp fastening. The connectors are mechanically and electrically interchangeable.

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

A: The primary differences are product status and RoHS compliance. The 644284-8 is obsolete and RoHS non-compliant, while the 3-644284-8 is an active product with ROHS3 compliance. Both parts are otherwise identical in form, fit, and function.

Q: Are there packaging differences between 644284-8 and 3-644284-8?

A: The 644284-8 packaging specification is not provided in the technical data. The 3-644284-8 is supplied in bulk packaging. Packaging configuration does not affect connector functionality or interchangeability.

Q: Does the RoHS compliance difference affect connector performance?

A: No. RoHS compliance status reflects manufacturing process and material composition standards, not connector electrical or mechanical performance. Both parts deliver identical functional performance in circuit applications.

Q: Can I use the 3-644284-8 in legacy systems designed for the 644284-8?

A: Yes. The 3-644284-8 is fully compatible with systems designed for the 644284-8. All electrical and mechanical parameters are identical, ensuring seamless integration into existing applications.

Q: What wire types are compatible with these connectors?

A: Both connectors support discrete or ribbon cable termination via IDC (Insulation Displacement Contact) method at 18 AWG wire gauge.

Q: Are these connectors suitable for high-reliability applications?

A: Both connectors feature gold contact finish with 15.0µin thickness, closed-end design with polarizing key, and MSL 1 (unlimited) moisture sensitivity rating, supporting applications requiring stable electrical performance and environmental protection.
