Substitute Part Grouping Explanation

Substitution of the 1-641191-0 is determined by strict equivalence across the following critical parameters:

Connector Type & Contact Configuration: Receptacle with female socket contacts
Position Count & Pitch: 10 positions at 0.100" (2.54mm) spacing
Termination Method: IDC (Insulation Displacement Connector) for discrete or ribbon cable
Wire Gauge Compatibility: 24 AWG
Contact Material & Finish: Gold plating at 15.0µin (0.38µm) thickness
Mechanical Interface: Free hanging (in-line) and right angle mounting with locking ramp fastening
Electrical & Environmental Ratings: Moisture Sensitivity Level 1 (unlimited), closed-end design

The substitute part 4-641191-0 maintains identical electrical and mechanical specifications while differing in product status and packaging configuration.

Engineering Selection Recommendations

The TE Connectivity 4-641191-0 serves as the direct substitute for the obsolete 1-641191-0. Both parts are manufactured by TE Connectivity AMP Connectors and maintain identical electrical and mechanical specifications across all critical parameters including connector type, position count, pitch, termination method, wire gauge, contact finish, and mounting configuration.

The primary distinction between these parts is product status: the 1-641191-0 is obsolete while the 4-641191-0 is active. The substitute part additionally carries RoHS Compliant certification, whereas the main part status is not applicable. Both parts satisfy Moisture Sensitivity Level 1 requirements and are classified under ECCN EAR99.

For new designs or ongoing procurement, the 4-641191-0 is the appropriate selection due to its active product status and RoHS compliance. For legacy system maintenance requiring the exact original part number, the 1-641191-0 remains available in inventory.

Frequently Asked Questions (FAQ)

Q: Can the 4-641191-0 be used as a direct replacement for the 1-641191-0?

A: Yes. Both parts are electrically and mechanically equivalent. They share identical specifications for connector type, position count, pitch, contact configuration, termination method, wire gauge, contact finish, and mounting interface. The 4-641191-0 is the active production equivalent.

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

A: The primary differences are product status and compliance certification. The 1-641191-0 is obsolete and marked as not applicable for RoHS status. The 4-641191-0 is an active product with RoHS Compliant certification. Packaging differs as well, with the substitute supplied in bulk configuration.

Q: Are there any compatibility concerns when substituting the 4-641191-0 for the 1-641191-0?

A: No compatibility concerns exist. Both parts maintain identical electrical and mechanical interfaces. They are designed for the same IDC termination process, accept 24 AWG wire, and feature identical contact geometry, pitch, and fastening mechanisms.

Q: Does the RoHS Compliant status of the 4-641191-0 affect its performance?

A: No. RoHS compliance indicates adherence to material composition restrictions and does not alter electrical or mechanical performance. The 4-641191-0 maintains all functional specifications of the original part.

Q: What packaging is supplied with each part?

A: The 1-641191-0 packaging is not specified in available documentation. The 4-641191-0 is supplied in bulk packaging configuration.

Q: Are both parts suitable for IDC termination with discrete or ribbon cable?

A: Yes. Both the 1-641191-0 and 4-641191-0 support IDC termination with discrete or ribbon cable at 24 AWG wire gauge.
