Engineering Selection Recommendations

Primary Recommendation: N3314-6002RB (3M)

The N3314-6002RB is the preferred substitute for the 3314-6202. This part maintains 3M manufacturing continuity, is currently in active production status, and holds RoHS compliance certification. The increased current rating of 1.75A provides enhanced electrical capacity over the original 1A specification. Operating temperature range remains -55°C to 105°C, maintaining thermal compatibility with the original design envelope.

Secondary Recommendations: HARTING SEK Series (09185145902, 09185145904, 09185146902, 09185146904, 09185147902)

HARTING SEK series connectors provide active production alternatives with ROHS3 compliance and extended operating temperature range to -55°C to 125°C. These parts maintain the 14-position, 2.54mm pitch configuration with shrouded 4-wall design. Fastening mechanisms differ from the original (Latch Lock/Eject Hooks, Long versus Short), requiring mechanical compatibility assessment for mating connector interfaces.

Right-Angle Variants: 09185146321, 09185147321 (HARTING)

Right-angle mounting options are available from HARTING (09185146321, 09185147321) for applications requiring perpendicular board orientation. These parts are suitable only when board layout permits right-angle connector mounting and are not direct mechanical substitutes for vertical mounting applications.

Compliance Consideration:

The original 3314-6202 is RoHS non-compliant. All recommended substitutes (N3314-6002RB and HARTING SEK series) are RoHS compliant or ROHS3 compliant, supporting modern regulatory requirements in manufacturing and procurement.

Frequently Asked Questions (FAQ)

Q: Can the N3314-6002RB directly replace the 3314-6202 in existing designs?

A: Yes. Both parts share identical pitch spacing (2.54mm), position count (14), row configuration (2x7), shrouding (4-wall), and through-hole mounting. The fastening mechanism differs (Push-Pull versus Latch Lock/Eject Hooks, Short), but this affects only the mating connector interface, not the header itself. Mating connectors must be compatible with the Push-Pull fastening type.

Q: What is the difference between the HARTING parts with "Long" versus "Short" fastening hooks?

A: Fastening hook length affects the mechanical engagement depth with mating connectors. "Long" hooks provide greater engagement depth and are typically used in applications requiring higher mechanical retention force. The original 3314-6202 uses "Short" hooks. HARTING substitutes with "Long" hooks require mating connectors designed for this longer engagement profile.

Q: Are the right-angle HARTING parts (09185146321, 09185147321) compatible with vertical mounting applications?

A: No. Right-angle parts are designed for perpendicular board mounting and cannot be used in applications requiring vertical connector orientation. These are suitable only for designs where board layout permits right-angle connector placement.

Q: What is the significance of the operating temperature difference between the original part (-55°C to 105°C) and HARTING substitutes (-55°C to 125°C)?

A: The extended upper temperature limit of HARTING parts provides additional thermal margin for high-temperature applications. If the original design operates within -55°C to 105°C, HARTING substitutes remain fully compatible. The extended range does not affect compatibility in standard temperature environments.

Q: Does the increased current rating of N3314-6002RB (1.75A versus 1A) affect compatibility?

A: No. Higher current rating indicates increased electrical capacity and does not affect mechanical or electrical compatibility. The part remains suitable for applications designed for 1A operation and provides additional capacity margin for future design iterations.

Q: Are all substitute parts available in the same packaging as the original 3314-6202?

A: Substitute parts are available in bulk packaging. Original packaging specifications should be confirmed with the supplier for specific procurement requirements.

Q: What compliance certifications apply to these substitute parts?

A: The N3314-6002RB holds RoHS compliance. HARTING SEK series parts (09185145329, 09185145902, 09185145904, 09185146321, 09185146902, 09185146904, 09185147321, 09185147902) hold ROHS3 compliance and REACH Unaffected status. All parts maintain UL94 V-0 material flammability rating.
