3M 3408-6305 Rectangular Connector Header - Equivalent & Substitute Parts

Part Overview

The 3M 3408-6305 is an active rectangular connector header designed for through-hole mounting applications. This shrouded 16-position connector with 2.54mm pitch serves board-to-board and cable interconnection requirements. The part features wire wrap termination with latch lock/eject hooks and operates across the -55°C to 105°C temperature range. Substitute parts are identified to address packaging availability, termination method requirements, and inventory considerations while maintaining core electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 3408-6305 is determined by the following core parameters that must remain constant across all alternatives:

• Connector type: Header
• Contact type: Male Pin
• Number of positions: 16
• Number of rows: 2
• Pitch - mating: 0.100" (2.54mm)
• Row spacing - mating: 0.100" (2.54mm)
• Mounting type: Through Hole
• Shrouding: Shrouded - 4 Wall
• Operating temperature range: -55°C ~ 105°C
• Material flammability rating: UL94 V-0
• Moisture sensitivity level: 1 (Unlimited)

The identified substitute parts D3408-6002-AR and N3408-6002RB maintain these critical parameters. Variations in termination method (wire wrap versus solder), fastening type (latch lock/eject hooks versus push-pull), contact post length, and current rating do not preclude substitution when application requirements permit these differences.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain active product status and comply with RoHS requirements, ensuring long-term availability and regulatory compliance. The 3408-6305 with wire wrap termination is suitable for applications requiring post-insertion wire wrapping techniques. The D3408-6002-AR and N3408-6002RB with solder termination are appropriate for applications utilizing standard PCB soldering processes.

D3408-6002-AR is packaged in trays and carries ROHS3 compliance. N3408-6002RB is packaged in bulk and carries standard RoHS compliance. Both substitute parts support higher current ratings of 1.75A compared to the 1A rating of the main part, providing additional margin in applications where current capacity is a design consideration.

Contact post length differences reflect the distinct termination methods: the 3408-6305 features extended posts for wire wrap insertion, while D3408-6002-AR and N3408-6002RB have shorter posts optimized for solder connection to PCB pads.

Frequently Asked Questions (FAQ)

Q: Can D3408-6002-AR or N3408-6002RB be used as direct replacements for 3408-6305?

A: Substitution is valid when the application design accommodates solder termination instead of wire wrap termination. The mating interface, pitch, shrouding, and operating temperature range are identical across all three parts. Verify that PCB pad layout and assembly process are compatible with the shorter contact post length of the substitute parts.

Q: What is the difference between D3408-6002-AR and N3408-6002RB?

A: Both parts share identical electrical and mechanical specifications. The primary differences are packaging format (D3408-6002-AR in trays, N3408-6002RB in bulk) and contact material (D3408-6002-AR uses brass, N3408-6002RB uses copper alloy). Contact finish thickness on the post also differs: D3408-6002-AR at 39.4µin versus N3408-6002RB at 200.0µin.

Q: Are there compatibility concerns with the different insulation materials?

A: The 3408-6305 uses PBT insulation while D3408-6002-AR and N3408-6002RB use PCT insulation. Both materials are polyester-based, glass-filled compounds rated UL94 V-0. The operating temperature range and flammability characteristics remain equivalent across all three parts.

Q: Does the higher current rating of the substitute parts affect compatibility?

A: The substitute parts are rated for 1.75A compared to 1A for the 3408-6305. This represents increased current capacity and does not create compatibility issues. Applications designed for 1A operation remain fully compatible with parts rated for 1.75A.

Q: What fastening type differences exist between these parts?

A: The 3408-6305 uses latch lock/eject hooks with long fastening, while D3408-6002-AR and N3408-6002RB use push-pull fastening. These differences affect mating connector engagement and release mechanisms. Verify that mating connectors are compatible with the fastening type of the selected part.
