Substitute Part Grouping Explanation

Substitution of the obsolete TE Connectivity 104319-8 with active alternatives is determined by strict equivalence across the following critical parameters:

Electrical and Mechanical Compatibility Criteria:

• Connector type, contact type, and gender (Header, Male Pin)
• Position count and row configuration (12 positions, 2 rows)
• Mating pitch and row spacing (0.100" / 2.54mm)
• Mounting orientation and method (Through Hole, Right Angle)
• Shrouding configuration (Shrouded - 4 Wall)
• Termination method (Solder)
• Fastening mechanism (Detent Lock)
• Contact material and insulation material specifications
• Operating temperature range (-65°C ~ 105°C)
• Current rating (3A)
• Flammability compliance (UL94 V-0)

The substitute part 5-103166-4 maintains full electrical and mechanical compatibility across all critical parameters while offering active product status and improved regulatory compliance.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity 5-103166-4 is the direct functional equivalent for the obsolete 104319-8 rectangular connector header. Selection of the substitute part is supported by the following engineering factors:

Product Status and Availability: The 104319-8 is classified as obsolete, while the 5-103166-4 maintains active product status with significantly higher inventory availability (4278 units in stock versus 899 units for the obsolete part).

Regulatory Compliance: The substitute part 5-103166-4 is RoHS compliant and carries defined REACH status (REACH Unaffected), whereas the main part is RoHS non-compliant with undefined REACH status. Both parts maintain identical UL94 V-0 flammability ratings and MSL 1 moisture sensitivity levels.

Contact Finish Specifications: The substitute part features gold plating on mating contacts at 30.0µin (0.76µm), exceeding the main part specification of 15.0µin (0.38µm). The post contact finish on the substitute uses pure tin rather than tin-lead, aligning with lead-free manufacturing standards while maintaining the identical 100.0µin thickness specification.

Electrical and Mechanical Equivalence: All critical electrical and mechanical parameters are identical between the main part and substitute, including connector type, position count, pitch spacing, mounting configuration, shrouding, termination method, fastening mechanism, contact material, insulation material, operating temperature range, and current rating.

Frequently Asked Questions (FAQ)

Q: Can the 5-103166-4 be used as a direct replacement for the 104319-8 in existing designs?

A: Yes. The 5-103166-4 maintains full electrical and mechanical compatibility with the 104319-8 across all critical parameters including connector type, position count, pitch spacing, mounting orientation, shrouding configuration, termination method, and fastening mechanism. Both parts are from the same AMPMODU Mod II series and share identical operating temperature ranges and current ratings.

Q: What are the differences between these two parts?

A: The primary differences are product status and regulatory compliance. The 104319-8 is obsolete with RoHS non-compliant status, while the 5-103166-4 is an active product with RoHS compliance and defined REACH status. The substitute part also features enhanced gold plating thickness on mating contacts (30.0µin versus 15.0µin) and uses lead-free tin plating on posts instead of tin-lead. These differences represent improvements that do not affect functional compatibility.

Q: Does the packaging difference affect compatibility?

A: No. The 104319-8 packaging is not specified in the documentation, while the 5-103166-4 is supplied in tray packaging. Packaging affects handling, storage, and logistics but does not impact the electrical or mechanical performance of the connector itself. The connector specifications and mating characteristics remain identical.

Q: Are there any temperature or current rating differences?

A: No. Both parts operate across the identical temperature range of -65°C to 105°C and carry the same 3A current rating. These critical performance parameters are fully equivalent.

Q: Why should the 5-103166-4 be selected over the 104319-8?

A: The 5-103166-4 should be selected because the 104319-8 is obsolete. The substitute part is actively manufactured, offers superior regulatory compliance (RoHS compliant, defined REACH status), provides enhanced contact plating specifications, and maintains full functional equivalence. Higher inventory availability of the substitute part also supports supply chain continuity.

Q: Is the lead-free tin finish on the 5-103166-4 compatible with tin-lead solder processes?

A: Both parts use solder termination and are compatible with standard PCB assembly processes. The contact finish material does not restrict the solder type used during assembly. The lead-free tin finish on the substitute part represents a manufacturing improvement aligned with current industry standards.

Q: What is the significance of the gold plating thickness difference?

A: The substitute part's increased gold plating thickness (30.0µin versus 15.0µin) on mating contacts provides enhanced durability and corrosion resistance without affecting electrical performance. This represents an improvement over the original specification and does not create any compatibility issues.
