Substitute Part Grouping Explanation

Substitution eligibility for the 1-103975-1 is determined by strict equivalence across the following critical parameters:

Connector Type & Contact Configuration: Receptacle with female socket contacts
Position Count & Pitch: 12 positions at 0.100" (2.54mm) spacing
Termination Method: IDC termination for ribbon cable
Wire Gauge Compatibility: 22-26 AWG
Contact Material & Finish: Gold plating at 15.0µin (0.38µm) thickness
Physical Form Factor: Single-row, free-hanging in-line mounting
Series Designation: AMPMODU MTE

The substitute part 6-103975-1 maintains identical electrical and mechanical specifications across all these parameters, ensuring direct functional interchangeability. Differences exist only in regulatory compliance status and inventory availability.

Engineering Selection Recommendations

Primary Selection (1-103975-1): This part is the baseline specification with confirmed active production status and higher inventory availability (1113 units). Selection is appropriate for applications without RoHS3 compliance mandates.

Substitute Selection (6-103975-1): This part is functionally identical to the primary part across all electrical and mechanical parameters. The key distinction is ROHS3 compliance certification. Selection of 6-103975-1 is required for applications subject to RoHS3 regulatory requirements or when procurement specifications mandate RoHS3-compliant components. The substitute maintains identical performance characteristics, contact ratings, and termination compatibility.

Both parts are classified as Moisture Sensitivity Level 1 (Unlimited), indicating no special moisture handling requirements during storage or assembly.

Frequently Asked Questions (FAQ)

Q: Are 1-103975-1 and 6-103975-1 electrically interchangeable?

A: Yes. Both parts are 12-position rectangular receptacle connectors with identical contact configurations, gold plating specifications, and IDC termination for 22-26 AWG ribbon cable. Electrical performance and contact resistance characteristics are equivalent.

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

A: The primary difference is RoHS compliance status. The 1-103975-1 is RoHS non-compliant, while the 6-103975-1 is ROHS3 compliant. All other specifications, including connector type, position count, pitch, contact finish, and wire gauge ratings, are identical.

Q: Can I substitute 6-103975-1 for 1-103975-1 in existing designs?

A: Yes, provided your application or procurement requirements do not explicitly prohibit RoHS3-compliant components. The mechanical and electrical specifications are fully compatible. Verify that your design documentation and compliance requirements align with the RoHS3 status of the substitute part.

Q: Are there any packaging differences between these parts?

A: No. Both parts are supplied in tube packaging. Inventory quantities differ (1113 units for 1-103975-1 and 937 units for 6-103975-1), but packaging format is identical.

Q: What wire gauges are supported by these connectors?

A: Both connectors support 22-26 AWG ribbon cable with IDC termination. The contact design and termination mechanism are rated for this wire gauge range.

Q: Do these connectors require special moisture handling?

A: No. Both parts carry a Moisture Sensitivity Level (MSL) rating of 1 (Unlimited), indicating no moisture sensitivity precautions are required during storage, handling, or assembly.

Q: What is the pitch specification for these connectors?

A: The pitch is 0.100 inches (2.54 millimeters) between adjacent contact positions in the 12-position array.
