Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 104479-4 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Socket contact type classification
• 20-24 AWG wire gauge specification
• Gold contact finish with 30.0µin (0.76µm) thickness
• Crimp termination method
• AMPMODU Short Point series designation
• Rectangular connector category
• Cut Tape packaging format

The substitute part 1-104479-0 satisfies all mandatory matching parameters and maintains functional and mechanical interchangeability with the primary part number 104479-4. Both components share identical electrical and mechanical specifications, enabling direct substitution in applications requiring socket contacts within the specified wire gauge and termination parameters.

Parameter Comparison

Engineering Selection Recommendations

104479-4 Selection Criteria: The 104479-4 is appropriate for applications where RoHS non-compliance is acceptable or where legacy system compatibility is required. This part number maintains Active product status and is available in high inventory quantities (60,257 pieces).

1-104479-0 Selection Criteria: The 1-104479-0 is the preferred substitute when RoHS compliance is mandated by design specifications, regulatory requirements, or customer procurement standards. This part number is RoHS Compliant and maintains equivalent electrical and mechanical performance. Higher inventory availability (70,342 pieces) supports supply chain continuity. Both parts share identical MSL, ECCN, and HTSUS classifications, ensuring consistent handling and regulatory treatment.

Compliance Consideration: The primary distinction between these part numbers is RoHS compliance status. Selection between 104479-4 and 1-104479-0 should be driven by project-specific compliance requirements rather than functional performance, as all electrical and mechanical parameters are identical.

Frequently Asked Questions (FAQ)

Q: Are 104479-4 and 1-104479-0 electrically interchangeable?

A: Yes. Both parts are socket contacts with identical wire gauge ratings (20-24 AWG), gold contact finish specifications (30.0µin thickness), and crimp termination methods. Electrical performance is equivalent.

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

A: The 104479-4 is RoHS non-compliant, while 1-104479-0 is RoHS Compliant. All other electrical, mechanical, and packaging specifications are identical.

Q: Can I substitute 1-104479-0 for 104479-4 in existing designs?

A: Yes, provided your application permits RoHS Compliant components. The substitute maintains identical contact specifications, wire gauge compatibility, and termination method.

Q: Are both parts available in the same packaging format?

A: Yes. Both 104479-4 and 1-104479-0 are supplied in Cut Tape (CT) packaging.

Q: What wire gauges are supported by these socket contacts?

A: Both parts support 20-24 AWG wire gauges exclusively.

Q: Do these parts have different moisture sensitivity requirements?

A: No. Both parts carry MSL 1 (Unlimited) classification, indicating no moisture sensitivity restrictions.

Q: Which part number should I specify for new designs?

A: Specify 1-104479-0 for new designs unless RoHS non-compliance is a specific design requirement. The RoHS Compliant variant provides broader regulatory compatibility and maintains identical performance characteristics.
