Substitute Part Grouping Explanation

Substitution between the main part 103974-7 and the equivalent part 5-103974-7 is based on the following criteria:

Mechanical Compatibility Parameters:

Identical connector type, position count, and pitch (0.100")
Matching row configuration and mounting method
Identical cable termination method (IDC) and wire gauge range (22-26 AWG)
Same physical form factor and closed-end design

Electrical Interface Parameters:

Identical contact type (female socket) and contact finish thickness (100.0µin)
Matching wire type (ribbon cable) and color (black)
Equivalent moisture sensitivity rating (MSL 1)

Differentiation Parameters:

Contact finish material: 103974-7 uses tin-lead; 5-103974-7 uses tin
RoHS compliance: 103974-7 is non-compliant; 5-103974-7 is compliant
HTSUS classification differs due to finish composition

These parts are electrically and mechanically interchangeable within applications where the specified contact finish and regulatory compliance requirements are met.

Engineering Selection Recommendations

Part 103974-7 (Tin-Lead Contact Finish): Select this part for applications where tin-lead contact finish is specified or required by design documentation. This part is Active and maintains full stock availability. Note that this part carries RoHS non-compliant status and is subject to applicable regulatory restrictions in certain jurisdictions.

Part 5-103974-7 (Tin Contact Finish): Select this part for applications requiring RoHS compliance. This substitute maintains identical mechanical and electrical interface specifications while providing compliant contact finish material. Higher inventory availability (1747 units) supports production requirements. Both parts share Active product status and equivalent moisture sensitivity ratings.

Selection Criteria:

Regulatory compliance requirements (RoHS)
Contact finish material specifications in design documentation
Supply chain and inventory considerations
Application-specific environmental or operational requirements

Both parts are mechanically and electrically interchangeable within their respective compliance frameworks.

Frequently Asked Questions (FAQ)

Q: Are parts 103974-7 and 5-103974-7 mechanically interchangeable?

A: Yes. Both parts feature identical connector geometry, pitch (0.100"), position count (8), and mounting configuration. They are direct mechanical substitutes.

Q: What is the primary difference between these two parts?

A: The primary difference is contact finish material. Part 103974-7 uses tin-lead finish, while part 5-103974-7 uses tin finish. Part 5-103974-7 is RoHS compliant; part 103974-7 is not.

Q: Can I use part 5-103974-7 in an application originally designed for 103974-7?

A: Yes, provided your application does not specifically require tin-lead contact finish. The tin contact finish of part 5-103974-7 maintains the same contact finish thickness (100.0µin) and electrical performance characteristics.

Q: Are there any electrical performance differences between these parts?

A: No. Both parts feature identical contact finish thickness, wire gauge compatibility (22-26 AWG), and IDC termination specifications. Electrical performance is equivalent.

Q: What does MSL 1 (Unlimited) mean for these connectors?

A: MSL 1 indicates the lowest moisture sensitivity level. These parts have unlimited shelf life and do not require special moisture-controlled storage conditions.

Q: Which part should I select for new designs?

A: For new designs, part 5-103974-7 is recommended due to RoHS compliance status, which aligns with current regulatory requirements in most markets. Both parts are Active and available.

Q: Are both parts available in the same packaging?

A: Yes. Both parts are supplied in tube packaging and are available as new original stock.

Q: Can these connectors be used with non-ribbon cable?

A: No. Both parts are specified for ribbon cable termination via IDC method. Wire type and gauge are fixed at 22-26 AWG ribbon cable.
