3M 3314-2203 Rectangular Connector Header - Equivalent & Substitute Parts

Part Overview

The 3M 3314-2203 is a through-hole rectangular connector header with 14 positions arranged in 2 rows at 0.100" (2.54mm) pitch. This shrouded 3-wall header features male pins with gold-plated mating contacts and tin-lead plated posts, designed for board-to-cable/wire applications. The part is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing design support and procurement.

Substitute Part Grouping Explanation

Substitution eligibility for the 3M 3314-2203 is determined by the following critical parameters:

Connector Type & Contact Type: Must be Header with Male Pin configuration
Position Count & Row Configuration: Must maintain 14 positions in 2-row arrangement
Pitch Specifications: Mating pitch and row spacing must both be 0.100" (2.54mm)
Mounting & Termination: Through-hole solder termination required
Contact Finish: Gold-plated mating surface with tin or tin-lead post finish
Operating Temperature Range: -55°C ~ 105°C minimum
Flammability Rating: UL94 V-0 compliance required
Current Rating: Minimum 1A capability

The substitute parts 3M 3314-6002 and 3M N3314-6002RB meet these core electrical and mechanical requirements. Variations in shrouding design (4-wall vs. 3-wall), fastening mechanism (push-pull vs. latch lock), and insulation material do not prevent functional substitution when mating interface geometry and electrical performance remain compatible.

Engineering Selection Recommendations

3M N3314-6002RB is the primary substitute for the 3314-2203. This part maintains full electrical and mechanical compatibility while offering active product status and RoHS compliance. The tin post finish (versus tin-lead) meets modern soldering standards and environmental regulations. Current rating of 1.75A matches the original specification.

3M 3314-6002 serves as a secondary substitute when N3314-6002RB is unavailable. This part shares identical electrical characteristics and mating interface geometry. The reduced current rating of 1A requires circuit-level verification if the original design operates above this threshold. Both parts are classified as obsolete; however, N3314-6002RB maintains active status with higher inventory availability.

The transition from 3-wall to 4-wall shrouding in both substitutes provides enhanced EMI shielding and mechanical robustness without affecting pin-to-pin compatibility or mating interface dimensions.

Frequently Asked Questions (FAQ)

Q: Can the 3314-6002 and N3314-6002RB be used interchangeably with the 3314-2203?

A: Both parts are mechanically and electrically compatible at the mating interface. The 14-position, 2-row configuration at 0.100" pitch is identical. Verify circuit current requirements against the 1A rating for 3314-6002 and 1.75A for N3314-6002RB.

Q: What is the difference between 3-wall and 4-wall shrouding?

A: Shrouding refers to the insulation walls surrounding the contact array. 4-wall shrouding provides additional mechanical protection and EMI containment compared to 3-wall design. Both configurations maintain the same mating interface and pin spacing.

Q: Does the change from tin-lead to tin post finish affect compatibility?

A: No. The post finish does not affect mating compatibility. Tin finish (N3314-6002RB) is compatible with modern lead-free soldering processes and meets current environmental standards, while tin-lead finish (3314-6002) is compatible with traditional soldering methods.

Q: Why is N3314-6002RB recommended over 3314-6002?

A: N3314-6002RB is active product status with higher inventory availability, RoHS compliance, and matches the original 1.75A current rating. The 3314-6002 is obsolete with reduced current rating.

Q: Are there mechanical differences in contact length?

A: The main part 3314-2203 has a post length of 0.155" (3.94mm), while both substitutes have 0.112" (2.84mm). This difference does not affect mating compatibility but may impact PCB layout considerations for through-hole depth and solder joint formation.

Q: What is the packaging difference between bulk and standard packaging?

A: Packaging designation indicates quantity per reel or tray. Bulk packaging typically represents larger quantities. Electrical and mechanical specifications remain identical regardless of packaging format.
