Substitute Part Grouping Explanation

The substitute part 5-104178-5 is functionally equivalent to the main part 104178-5 based on the following critical parameters that determine substitution validity:

Matching Parameters:

• Connector type (Header)
• Contact type (Male Pin)
• Number of positions (8)
• Pitch spacing (0.050" / 1.27mm)
• Mounting type (Through Hole)
• Termination method (Solder)
• Operating temperature range (-65°C ~ 105°C)
• Voltage rating (30VAC)
• Material flammability rating (UL94 V-0)
• Series designation (AMPMODU System 50)
• Contact geometry (Square shape, 0.120" mating length, 0.100" post length)
• Insulation specifications (0.100" height, Black thermoplastic)

Distinguishing Characteristics: The substitute part differs in product status (Active vs. Obsolete), packaging configuration (Bulk vs. standard), contact finish on the post (Tin vs. Tin-Lead), and regulatory compliance status (ROHS3 Compliant vs. RoHS non-compliant).

Parameter Comparison

Engineering Selection Recommendations

The substitute part 5-104178-5 is the direct equivalent for the obsolete 104178-5. Selection of the substitute part is based on the following engineering criteria:

Product Status: The main part 104178-5 is classified as obsolete, while the substitute 5-104178-5 maintains active product status. This distinction is critical for long-term supply chain continuity and component availability.

Regulatory Compliance: The substitute part 5-104178-5 is ROHS3 compliant, whereas the main part is RoHS non-compliant. This compliance difference is significant for applications subject to European Union Restriction of Hazardous Substances regulations and equivalent international standards.

Contact Finish Specification: The substitute part features a Tin post finish, compared to the Tin-Lead finish of the main part. Both finishes maintain the specified 150.0µin (3.81µm) thickness and are compatible with solder termination processes.

Electrical and Mechanical Compatibility: All critical electrical parameters (voltage rating, operating temperature range, contact geometry) and mechanical parameters (pitch spacing, mounting type, insulation dimensions) are identical between the main part and substitute part. The connectors are mechanically and electrically interchangeable within the AMPMODU System 50 series.

Inventory Availability: The substitute part 5-104178-5 is available in significantly higher quantities (4694 Pcs) compared to the main part (1025 Pcs), supporting procurement reliability for production applications.

Frequently Asked Questions (FAQ)

Q: Are the 104178-5 and 5-104178-5 connectors mechanically interchangeable?

A: Yes. Both connectors share identical mechanical specifications including 8-position configuration, 0.050" (1.27mm) pitch spacing, through-hole mounting, square contact geometry, and overall contact dimensions. They are mechanically interchangeable within the AMPMODU System 50 series.

Q: What is the difference in contact finish between these parts?

A: The main part 104178-5 features a Tin-Lead post finish, while the substitute 5-104178-5 features a Tin post finish. Both maintain 150.0µin (3.81µm) thickness. The mating contact finish (Gold, 30.0µin) is identical on both parts. Both finishes are compatible with standard solder termination processes.

Q: Why is the substitute part ROHS3 compliant while the main part is not?

A: The substitute part 5-104178-5 was manufactured to comply with ROHS3 (Restriction of Hazardous Substances Directive 3) standards, which restrict the use of lead and other hazardous substances. The main part 104178-5, being obsolete, was manufactured under earlier standards that permitted Tin-Lead finishes. The Tin post finish on the substitute part eliminates lead content.

Q: Are the electrical specifications identical between these connectors?

A: Yes. Both connectors have identical voltage ratings (30VAC), operating temperature ranges (-65°C ~ 105°C), material flammability ratings (UL94 V-0), and moisture sensitivity levels (MSL 1 - Unlimited). They are electrically equivalent for all specified applications.

Q: What packaging differences exist between the main part and substitute?

A: The main part 104178-5 is supplied in standard packaging, while the substitute 5-104178-5 is supplied in bulk packaging. This distinction affects handling and storage procedures but does not impact connector functionality or performance.

Q: Can the 5-104178-5 be used as a direct replacement in existing designs?

A: Yes. The 5-104178-5 is a direct functional equivalent to the 104178-5. All mechanical, electrical, and thermal specifications are identical. The primary design consideration is the post contact finish change from Tin-Lead to Tin, which is compatible with standard solder assembly processes.

Q: What is the significance of the product status difference?

A: The main part 104178-5 is classified as obsolete, indicating it is no longer in active production. The substitute 5-104178-5 is classified as active, meaning it is currently manufactured and supported by TE Connectivity. For new designs and ongoing production, the active substitute part ensures long-term supply chain availability and manufacturer support.
