3906-0000T Equivalent & Substitute Parts

Part Overview

The 3906-0000T is a 6-position ribbon cable DIP header connector manufactured by 3M, designed for IDC termination with 26-28 AWG stranded wire. This connector features a through-hole mounting configuration with 0.050" cable pitch and 0.100" board-side pitch, suitable for applications requiring feed-through connectivity in a dual-row arrangement.

The 3906-0000T is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain design continuity and ensure component availability for new production runs, repairs, and system upgrades where this connector type is specified.

Substitute Part Grouping Explanation

Substitution of the 3906-0000T is determined by strict equivalence across the following critical parameters:

Connector Configuration: 6-position, 2-row DIP header with ribbon cable interface
Pitch Specifications: 0.050" cable pitch and 0.100" board-side pitch with 0.100" row spacing
Termination Method: IDC (Insulation Displacement Contact) cable termination
Mounting Interface: Through-hole PCB mounting
Electrical Compatibility: Feed-through contact arrangement
Wire Gauge Compatibility: Support for 26-28 AWG stranded conductors

The substitute part 7-215570-6 meets all critical dimensional and functional parameters required for direct substitution in applications originally designed for the 3906-0000T.

Engineering Selection Recommendations

The 7-215570-6 from TE Connectivity AMP Connectors is the active equivalent substitute for the obsolete 3906-0000T. This part maintains full dimensional and functional compatibility across all critical parameters: 6-position configuration, dual-row arrangement, 0.050" cable pitch, 0.100" board-side pitch, through-hole mounting, and IDC termination.

The 7-215570-6 offers additional advantages in terms of product lifecycle status. As an active product in the Micro-MaTch series, it provides assured long-term availability and supply continuity. The part is ROHS3 compliant and carries MSL 1 rating, meeting modern environmental and reliability standards. The contact finish is tin rather than tin-lead, aligning with current manufacturing practices.

Wire gauge compatibility is maintained at 28 AWG, which falls within the 26-28 AWG specification of the original part. The 7-215570-6 supports both stranded and solid conductors, providing design flexibility for ribbon cable applications.

Frequently Asked Questions (FAQ)

Q: Can the 7-215570-6 be used as a direct replacement for the 3906-0000T in existing designs?

A: Yes. Both connectors share identical pitch specifications (0.050" cable pitch, 0.100" board-side pitch), 6-position dual-row configuration, through-hole mounting, and IDC termination. PCB footprints and cable interfaces are compatible.

Q: What is the difference in mounting between these two connectors?

A: The 3906-0000T uses standard through-hole mounting. The 7-215570-6 supports both through-hole and press-fit mounting options, providing installation flexibility while maintaining backward compatibility with through-hole designs.

Q: Are there wire gauge differences between these connectors?

A: The 3906-0000T is rated for 26-28 AWG stranded wire. The 7-215570-6 is rated for 28 AWG stranded or solid wire. The 28 AWG specification of the substitute falls within the original specification range and is fully compatible.

Q: What is the significance of the contact finish difference (Tin-Lead vs. Tin)?

A: The 3906-0000T uses tin-lead plating. The 7-215570-6 uses tin plating, which is standard in current manufacturing and complies with ROHS3 requirements. Both finishes provide equivalent electrical performance and corrosion resistance for this connector class.

Q: Why is the 3906-0000T listed as obsolete?

A: The 3906-0000T is an older 3M connector design. The 7-215570-6 represents the current active equivalent from TE Connectivity, offering the same functionality with modern compliance certifications and assured supply availability.

Q: Does the MSL rating difference affect substitution?

A: The 3906-0000T has no MSL rating specified. The 7-215570-6 carries MSL 1 (Unlimited), indicating superior moisture resistance and handling flexibility. This represents an improvement for storage and manufacturing environments.
