3M 3314-5205 Rectangular Connector Header - Equivalent & Substitute Parts

Part Overview

The 3M 3314-5205 is a through-hole, right-angle rectangular connector header with 14 positions at 2.54mm pitch, designed for board-to-cable/wire applications. This component features shrouded 4-wall construction with wire wrap termination and latch lock/eject fastening. The part is classified as obsolete, making identification of functionally equivalent active alternatives necessary for ongoing design support and procurement.

Substitute Part Grouping Explanation

Substitution eligibility for the 3314-5205 is determined by the following critical parameters:

Connector configuration: 14-position, 2-row header with 0.100" (2.54mm) pitch and row spacing
Mounting and orientation: Through-hole, right-angle mounting with shrouded 4-wall construction
Electrical performance: 1.75A current rating and -55°C to 105°C operating temperature range
Contact geometry: 0.240" (6.10mm) mating contact length and 0.340" (8.64mm) insulation height
Compliance: UL94 V-0 flammability rating and MSL 1 moisture sensitivity

The identified substitutes D3314-5002-AR and N3314-5002RB maintain these core parameters while differing in termination method (solder vs. wire wrap), fastening type (push-pull vs. latch lock), contact post length, and product status (active vs. obsolete).

Engineering Selection Recommendations

Both D3314-5002-AR and N3314-5002RB are active product alternatives to the obsolete 3314-5205. Selection between these substitutes depends on termination and fastening requirements:

D3314-5002-AR is recommended for applications requiring solder termination with push-pull fastening. This part carries RoHS Compliant certification and is packaged in trays, suitable for automated assembly processes.

N3314-5002RB is recommended for applications requiring solder termination with push-pull fastening where bulk packaging is acceptable. This part also carries RoHS Compliant certification and REACH Unaffected status.

Both substitutes maintain identical mating contact geometry, pitch, row spacing, operating temperature range, current rating, and flammability compliance as the original 3314-5205. The primary design consideration is the transition from wire wrap termination to solder termination and from latch lock fastening to push-pull fastening, which may require PCB layout and connector housing modifications.

Frequently Asked Questions (FAQ)

Q: Can D3314-5002-AR or N3314-5002RB be used as direct drop-in replacements for 3314-5205?

A: Both parts maintain the same mating contact pitch (0.100"), row spacing (0.100"), number of positions (14), and insulation height (0.340"). However, they differ in contact post length (0.112" vs. 0.610"), termination method (solder vs. wire wrap), and fastening type (push-pull vs. latch lock). PCB footprint and connector housing compatibility must be verified before substitution.

Q: What is the difference between D3314-5002-AR and N3314-5002RB?

A: Both parts are functionally equivalent with identical electrical and mechanical specifications. The primary differences are packaging (tray vs. bulk) and contact material (brass vs. copper alloy). D3314-5002-AR is packaged in trays for automated assembly, while N3314-5002RB is supplied in bulk. Both are RoHS Compliant and active products.

Q: Are the substitute parts RoHS compliant?

A: Yes, both D3314-5002-AR and N3314-5002RB are RoHS Compliant. The original 3314-5205 does not specify RoHS status.

Q: What is the impact of changing from wire wrap to solder termination?

A: Wire wrap termination (3314-5205) requires wire wrap posts of 0.610" length. Solder termination (D3314-5002-AR and N3314-5002RB) uses shorter posts of 0.112" length. This requires PCB redesign with different pad layouts and hole depths. Assembly processes must also transition from wire wrap equipment to solder reflow or wave soldering.

Q: What is the difference between latch lock and push-pull fastening?

A: The 3314-5205 uses latch lock/eject hooks for secure mating with short fastening engagement. The substitute parts use push-pull fastening, which provides different mating force characteristics and engagement mechanics. Connector housing compatibility must be verified.

Q: Are all three parts rated for the same current and temperature range?

A: Yes, all three parts (3314-5205, D3314-5002-AR, and N3314-5002RB) are rated for 1.75A current and -55°C to 105°C operating temperature range.
