Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete 644043-3 with the active equivalent 3-644043-3 is based on strict electrical and mechanical parameter alignment. Both parts share identical specifications across all critical substitution criteria:

Key Parameters Determining Substitution:

• Connector type, position count, and pitch (0.100")
• Contact configuration (Female Socket, 3 positions)
• Cable termination method (IDC) and wire gauge (26 AWG)
• Contact finish material and thickness (Gold, 30.0µin)
• Mounting and fastening characteristics (Free Hanging, Locking Ramp)
• Series designation (MTA-100)
• Mechanical form factor and color (Blue, Closed End)

The substitute part 3-644043-3 is manufactured by the same supplier (TE Connectivity AMP Connectors) and maintains full compatibility with applications designed for the original 644043-3. The primary distinction is product status: the original part is obsolete, while the substitute is active with significantly higher inventory availability (3918 Pcs vs. 810 Pcs).

Parameter Comparison

Engineering Selection Recommendations

The substitute part 3-644043-3 is the direct equivalent for the obsolete 644043-3. Selection of the substitute is based on the following engineering factors:

Product Status: The original 644043-3 is classified as obsolete, indicating discontinued manufacturing and limited long-term availability. The substitute 3-644043-3 maintains active product status with current manufacturing support.

Compliance and Certifications: Both parts maintain equivalent regulatory compliance. The original part is ROHS3 Compliant, while the substitute is RoHS Compliant. Both carry identical ECCN (EAR99) and HTSUS (8536.69.8000) classifications, ensuring consistent export and trade compliance.

Electrical and Mechanical Compatibility: All electrical parameters (contact type, pitch, wire gauge, contact finish) and mechanical parameters (mounting type, fastening method, form factor) are identical between the original and substitute parts. Direct functional interchangeability is established.

Inventory and Supply Chain: The substitute part offers significantly higher inventory availability (3918 Pcs vs. 810 Pcs), supporting both immediate procurement needs and long-term supply chain planning.

For new designs and ongoing production, the active substitute part 3-644043-3 is the appropriate selection. For legacy system maintenance requiring the original part number, the substitute provides full functional equivalence with improved availability.

Frequently Asked Questions (FAQ)

Q: Can 3-644043-3 be used as a direct replacement for 644043-3 in existing applications?

A: Yes. The substitute part 3-644043-3 is electrically and mechanically identical to 644043-3 across all specified parameters. Both parts are 3-position rectangular receptacle connectors with IDC termination, 26 AWG wire gauge, gold contacts, 0.100" pitch, and identical mounting characteristics. Direct substitution is supported without design modification.

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

A: The primary differences are product status and packaging. The original 644043-3 is obsolete with limited inventory (810 Pcs), while 3-644043-3 is an active product with higher availability (3918 Pcs). The substitute is supplied in bulk packaging. All electrical and mechanical specifications are identical.

Q: Are there any compliance or certification differences between these parts?

A: Both parts maintain equivalent regulatory compliance. The original is ROHS3 Compliant; the substitute is RoHS Compliant. Both share identical ECCN (EAR99) and HTSUS (8536.69.8000) classifications. Moisture Sensitivity Level (MSL 1) is identical for both parts.

Q: What parameters must remain identical for substitution to be valid?

A: Substitution validity is determined by matching specifications in the following categories: connector type (rectangular receptacle), position count (3), pitch (0.100"), contact type (female socket), cable termination method (IDC), wire gauge (26 AWG), contact finish (gold, 30.0µin thickness), mounting type (free hanging, right angle), fastening type (locking ramp), series designation (MTA-100), and form factor (closed end, blue color).

Q: Is the substitute part suitable for new product designs?

A: Yes. The substitute part 3-644043-3 is the recommended selection for new designs. It maintains active product status with current manufacturing support and superior inventory availability compared to the obsolete original part.

Q: What is the significance of the "3-" prefix in the substitute part number?

A: The "3-" prefix indicates a variant designation within the TE Connectivity product line. In this case, it identifies the active equivalent of the base product 644043. The electrical and mechanical specifications remain identical to the original 644043-3.

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

A: Yes. Both the original and substitute parts support discrete or ribbon cable termination via IDC (Insulation Displacement Contact) method at 26 AWG wire gauge.
