Substitute Part Grouping Explanation

Substitution eligibility for the TE Connectivity 104893-3 is determined by strict equivalence across all electrical and mechanical parameters. The substitute part 5-104893-3 qualifies as a direct equivalent based on the following criteria:

Critical Substitution Parameters:

• Identical connector type (Receptacle) and contact type (Female Socket)
• Identical position count (30 positions) and pitch configuration (0.050" / 1.27mm)
• Identical row configuration (2 rows with 0.050" / 1.27mm spacing)
• Identical cable termination method (IDC) and wire gauge specification (28 AWG)
• Identical contact finish material (Gold) and finish thickness (30.0µin / 0.76µm)
• Identical mounting type (Free Hanging In-Line) and design features (Closed End)
• Identical color specification (Black)
• Same series designation (AMPMODU 50/50 Grid)

The substitute part maintains full electrical and mechanical compatibility with the original part number while offering alternative compliance certifications and inventory availability.

Parameter Comparison

Engineering Selection Recommendations

• Higher inventory availability (1002 units versus 945 units)

Both parts share identical MSL rating (1 - Unlimited), ECCN classification (EAR99), and HTSUS code (8536.69.4051), indicating equivalent handling, export, and tariff classification. The substitute part 5-104893-3 offers enhanced compliance documentation while maintaining full electrical and mechanical interchangeability.

Frequently Asked Questions (FAQ)

Q: Are the 104893-3 and 5-104893-3 electrically interchangeable?

A: Yes. Both parts are identical in all electrical parameters including contact type, position count, pitch, wire gauge, contact finish, and finish thickness. They function identically in circuit applications.

Q: Are the 104893-3 and 5-104893-3 mechanically interchangeable?

A: Yes. Both parts share identical mechanical specifications including connector type, mounting configuration, row spacing, cable termination method, and physical dimensions. They mount and interface identically.

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

A: The primary differences are compliance certifications and inventory location. The 5-104893-3 carries ROHS3 Compliant status and REACH Unaffected designation, while the 104893-3 is marked as Not applicable for RoHS and REACH Affected. Both are active production parts with equivalent technical specifications.

Q: Can I use 5-104893-3 as a replacement for 104893-3 in existing designs?

A: Yes. The 5-104893-3 is a direct substitute with identical electrical and mechanical parameters. No design modifications are required. The substitute part offers enhanced compliance certifications.

Q: What does IDC termination mean for this connector?

A: IDC (Insulation Displacement Contact) termination allows the connector to pierce through ribbon cable insulation without requiring pre-stripped wire ends. The connector is designed for 28 AWG ribbon cable.

Q: What is the pitch specification and why is it important?

A: Pitch is the center-to-center distance between adjacent contacts, specified as 0.050" (1.27mm). This dimension determines physical compatibility with mating connectors and PCB layouts. Both parts have identical pitch specifications.

Q: What does Closed End design mean?

A: Closed End indicates the connector housing has sealed ends, providing protection and strain relief for the ribbon cable connection. Both parts feature this design.

Q: Are there any moisture sensitivity concerns with these connectors?

A: Both parts carry MSL rating 1 (Unlimited), indicating no moisture sensitivity limitations. These connectors do not require special moisture control during storage or handling.

Q: What is the significance of the gold contact finish?

A: Gold plating provides corrosion resistance and reliable electrical contact. Both parts specify 30.0µin (0.76µm) gold finish thickness, ensuring consistent contact performance and longevity.

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

A: These connectors are specifically designed for IDC termination with ribbon cable at 28 AWG. The IDC contact design is optimized for ribbon cable geometry and should not be used with other cable types.
