Substitute Part Grouping Explanation

Substitution eligibility for the 3408-630T02TC is determined by the following critical parameters:

Connector Configuration: 16-position, 2-row header with 0.100" (2.54mm) mating pitch and 0.100" row spacing
Mounting Method: Through-hole mounting capability
Shrouding Design: 4-wall shrouded construction
Contact System: Male pin contacts with gold-plated mating surfaces
Electrical Performance: Minimum 1A current rating at operating temperature range of -55°C to 105°C
Compliance: UL94 V-0 flammability rating and RoHS compliance

The identified substitute parts D3408-6002-AR and N3408-6002RB meet these core substitution criteria while maintaining functional and electrical compatibility with the original 3408-630T02TC design.

Engineering Selection Recommendations

Both D3408-6002-AR and N3408-6002RB are active product alternatives to the obsolete 3408-630T02TC. Selection between these substitutes should be based on the following factors:

D3408-6002-AR is classified as ROHS3 Compliant and belongs to the D3000 series. This part is available in tray packaging with 6514 units in stock, providing higher availability for volume applications. The current rating of 1.75A exceeds the original specification.

N3408-6002RB maintains the original 3000 series designation and is RoHS Compliant. This part is available in bulk packaging with 773 units in stock. The current rating of 1.75A also exceeds the original specification.

Both substitutes maintain identical connector geometry, pitch, shrouding configuration, and operating temperature range. The choice between them depends on packaging requirements, supply chain preferences, and compliance certification alignment with your application's regulatory framework.

Frequently Asked Questions (FAQ)

Q: Can D3408-6002-AR and N3408-6002RB be used interchangeably with 3408-630T02TC?

A: Both parts meet the core substitution criteria: 16-position, 2-row header configuration with 0.100" (2.54mm) pitch, through-hole mounting, 4-wall shrouding, male pin contacts, and gold-plated mating surfaces. Both operate across the same temperature range (-55°C to 105°C) and maintain UL94 V-0 flammability compliance. The substitutes provide higher current ratings (1.75A versus 1A), which is compatible with the original design envelope.

Q: What are the key differences between the two substitute parts?

A: D3408-6002-AR belongs to the D3000 series with ROHS3 compliance and tray packaging. N3408-6002RB belongs to the 3000 series with RoHS compliance and bulk packaging. Both have identical electrical and mechanical specifications for connector configuration, pitch, shrouding, and operating temperature. The primary distinction is series designation, packaging format, and compliance certification level.

Q: Are there packaging or termination differences I should consider?

A: D3408-6002-AR is supplied in tray packaging, while N3408-6002RB is supplied in bulk packaging. The original 3408-630T02TC supported both press-fit and solder termination; both substitutes support solder termination. Verify your assembly process compatibility with solder-only termination before selection.

Q: Do the substitute parts maintain the same contact material specifications?

A: D3408-6002-AR uses brass contact material, while N3408-6002RB uses copper alloy contact material. Both materials are compatible with the gold-plated mating surface finish and maintain electrical performance within the specified current and temperature ranges.

Q: What is the moisture sensitivity level for these substitutes?

A: Both D3408-6002-AR and N3408-6002RB are classified as MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.
