3M 3314-52K2 Rectangular Connector Header - Equivalent & Substitute Parts

Part Overview

The 3M 3314-52K2 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 latch lock/eject hooks and kinked pin solder termination. The part is classified as obsolete, making identification of functionally equivalent active alternatives essential for ongoing design support and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 3314-52K2 is determined by strict equivalence across the following critical parameters:

• Connector type (Header)
• Contact type (Male Pin)
• Position count (14 positions)
• Row configuration (2 rows)
• Mating pitch (0.100" / 2.54mm)
• Row spacing (0.100" / 2.54mm)
• Mounting style (Through Hole, Right Angle)
• Shrouding configuration (Shrouded - 4 Wall)
• Contact shape (Square)
• Insulation material (PCT, Polyester, Glass Filled)
• Operating temperature range (-55°C ~ 105°C)
• Current rating (1.75A)
• Flammability rating (UL94 V-0)
• MSL rating (1 - Unlimited)

The identified substitute parts D3314-5002-AR and N3314-5002RB maintain full compatibility across all critical mating and mechanical parameters. Variations in contact finish specifications, fastening mechanisms, and RoHS compliance status do not affect functional interchangeability in standard applications.

Parameter Comparison

Engineering Selection Recommendations

Both D3314-5002-AR and N3314-5002RB are functionally equivalent substitutes for the obsolete 3314-52K2 across all critical mating and mechanical parameters.

D3314-5002-AR is classified as the manufacturer-recommended substitute. This part carries active product status and RoHS compliance certification. The tray packaging format supports automated assembly processes. The push-pull fastening mechanism represents a design evolution from the original latch lock configuration.

N3314-5002RB maintains active product status and RoHS compliance. This part is supplied in bulk packaging. Contact material composition (copper alloy) and post-side contact finish thickness (200.0µin) align with the original 3314-52K2 specification, providing the closest material and finish profile match.

Selection between these substitutes should be based on procurement requirements, packaging preferences, and assembly process compatibility rather than electrical or mechanical performance, as both parts satisfy the functional requirements of the original component.

Frequently Asked Questions (FAQ)

Q: Are D3314-5002-AR and N3314-5002RB fully interchangeable with 3314-52K2?

A: Yes. Both substitute parts maintain identical mating pitch (0.100" / 2.54mm), row spacing (0.100" / 2.54mm), position count (14), row configuration (2), mounting style (through-hole right-angle), shrouding (4-wall), contact shape (square), and electrical ratings (1.75A, -55°C ~ 105°C). Functional interchangeability is confirmed across all critical parameters.

Q: What is the difference between the two substitute parts?

A: D3314-5002-AR and N3314-5002RB differ in packaging format (tray vs. bulk), fastening mechanism (push-pull vs. original latch lock), contact material composition (brass vs. copper alloy), and contact finish specifications. Both parts are electrically and mechanically equivalent for standard applications.

Q: Why does the original 3314-52K2 show as obsolete?

A: The 3314-52K2 is classified as obsolete due to product lifecycle discontinuation. The substitute parts D3314-5002-AR and N3314-5002RB represent the current active product offerings from 3M that maintain full functional equivalence.

Q: Does RoHS compliance status affect substitution eligibility?

A: The original 3314-52K2 is RoHS non-compliant, while both substitute parts are RoHS compliant. This difference reflects regulatory evolution and does not affect electrical or mechanical interchangeability. Selection should account for end-application regulatory requirements.

Q: Which substitute part should be selected for new designs?

A: Both D3314-5002-AR and N3314-5002RB are suitable for new designs. D3314-5002-AR is the manufacturer-recommended option. Selection between them should be based on packaging requirements (tray for automated assembly vs. bulk for manual assembly) and procurement volume considerations.

Q: Are there differences in contact finish that affect performance?

A: Contact finish variations exist between parts (mating-side gold thickness ranges from 10.0µin to 30.0µin; post-side tin thickness ranges from 39.4µin to 200.0µin). These differences do not affect functional performance in standard applications. Contact finish selection should align with specific environmental or reliability requirements if applicable.
