Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 1-111446-1 are identified based on electrical and mechanical parameter equivalence. The following parameters establish substitution eligibility:

Critical Matching Parameters:

• Connector Type: Plug
• Number of Positions: 50
• Pitch: 0.100" (2.54mm)
• Number of Rows: 2
• Row Spacing: 0.100" (2.54mm)
• Cable Termination: IDC
• Wire Gauge: 26-28 AWG
• Contact Finish: Gold
• Contact Finish Thickness: 30.0µin (0.76µm)
• Mounting Type: Free Hanging (In-Line)
• Features: Feed Through

Substitute parts meeting all critical parameters are classified as direct equivalents. Variations in packaging, product status, manufacturer, wire type flexibility, or color do not affect functional interchangeability when all electrical and mechanical parameters align.

Engineering Selection Recommendations

1-111446-7 (TE Connectivity AMP Connectors)

The 1-111446-7 is the primary direct substitute for the obsolete 1-111446-1. Both connectors are manufactured by TE Connectivity AMP Connectors within the AMP-Latch series and share identical electrical and mechanical specifications. The 1-111446-7 carries Active product status and is RoHS Compliant, providing regulatory compliance advantages over the non-compliant main part. This connector is available in Tray packaging with 1194 units in stock. Selection of the 1-111446-7 is appropriate for new designs, production continuity, and field replacements where TE Connectivity AMP Connectors compatibility is required.

4650-6001 (3M)

The 4650-6001 is a similar substitute manufactured by 3M within the 4600 series. This connector meets all critical electrical and mechanical parameters and is ROHS3 Compliant. The 4650-6001 supports both discrete and ribbon cable wire types, providing additional application flexibility compared to the ribbon cable-only specification of the main part. The connector is available in Bulk packaging with 1276 units in stock. The 4650-6001 is suitable for applications where cross-manufacturer compatibility is acceptable and discrete wire termination capability is beneficial. Color variation (Gray versus Black) does not affect electrical or mechanical function.

Frequently Asked Questions (FAQ)

Q: Can the 1-111446-7 be used as a direct replacement for the 1-111446-1?

A: Yes. The 1-111446-7 is a direct substitute. Both connectors share identical specifications for connector type, position count, pitch, row configuration, termination method, wire gauge, contact finish, and mounting type. The primary differences are product status (Active versus Obsolete) and RoHS compliance status.

Q: What is the difference between the 1-111446-1 and 1-111446-7 packaging?

A: The 1-111446-1 packaging is not specified in available documentation. The 1-111446-7 is supplied in Tray packaging. Packaging differences do not affect connector function or interchangeability.

Q: Can the 3M 4650-6001 be used in place of the TE Connectivity 1-111446-1?

A: Yes. The 4650-6001 meets all critical electrical and mechanical parameters. The connector is functionally equivalent for 50-position, 0.100" pitch, IDC-terminated applications. The 4650-6001 supports both discrete and ribbon cable configurations, whereas the 1-111446-1 is specified for ribbon cable. Cross-manufacturer substitution is valid when system design permits.

Q: Are there color differences between substitute parts?

A: Yes. The 1-111446-1 and 1-111446-7 are Black. The 4650-6001 is Gray. Color is a cosmetic parameter and does not affect electrical or mechanical function.

Q: What is the significance of RoHS compliance status in selecting a substitute?

A: The 1-111446-1 is RoHS non-compliant. The 1-111446-7 is RoHS Compliant, and the 4650-6001 is ROHS3 Compliant. For applications subject to RoHS regulations or customer requirements, the 1-111446-7 or 4650-6001 are appropriate selections. For legacy systems without RoHS requirements, all three connectors are functionally equivalent.

Q: Can the 4650-6001 accept both stranded and solid wire?

A: Yes. The 4650-6001 is specified for 26-28 AWG stranded or solid wire. The 1-111446-1 and 1-111446-7 are specified for ribbon cable. This additional flexibility in the 4650-6001 does not prevent its use in ribbon cable applications.

Q: What is the contact finish thickness specification?

A: All three connectors specify 30.0µin (0.76µm) gold contact finish thickness. This parameter is identical across all parts and does not differentiate substitution eligibility.

Q: Are there inventory considerations when selecting a substitute?

A: The 1-111446-1 has 876 units in stock. The 1-111446-7 has 1194 units in stock. The 4650-6001 has 1276 units in stock. Inventory levels may influence procurement decisions based on delivery requirements and lead time considerations.
