Engineering Selection Recommendations

Direct Equivalent (Highest Compatibility): The 3M 3314-6002 represents the closest equivalent to the 3314-6002UG, differing only in packaging format (bulk versus individual). Both parts share identical electrical and mechanical specifications with Push-Pull fastening and square contact geometry. However, both are classified as obsolete.

Active Product Replacement with Enhanced Compliance: The 3M N3314-6002RB is the recommended active product replacement. It maintains the same connector geometry, pitch, and fastening mechanism as the original part while offering RoHS compliance and increased current rating (1.75A versus 1A). The insulation material transitions from PBT to PCT, and the post finish changes from tin-lead to tin. This part is actively manufactured and stocked.

Alternative Manufacturers - CW Industries Series: CW Industries offers multiple substitute options across the CWN series. All CW Industries substitutes provide ROHS3 compliance and extended operating temperature range (-55°C ~ 125°C). The primary trade-offs involve:

Fastening Type Variation: CWN-360 series maintains Push-Pull fastening identical to the original. CWN-351, CWN-352, CWN-551, and CWN-552 series employ Latch Lock/Eject Hooks fastening, which provides different mating/unmating characteristics.
Contact Geometry: CW Industries parts feature circular contacts versus the square contacts of the 3M original, affecting insertion force and contact resistance characteristics.
Post Length Variation: CWN-360 and CWN-361 series offer 0.155" post length, while CWN-351, CWN-352, CWN-551, and CWN-552 series provide 0.090" post length.

Selection Criteria: For applications requiring direct form-factor compatibility with existing mating connectors, the 3M N3314-6002RB is the primary choice. For new designs or applications where fastening mechanism flexibility exists, CW Industries CWN-360-14-0000 or CWN-360-14-0021 provide active product status with Push-Pull fastening and RoHS compliance. Applications requiring latch-lock fastening should specify CWN-351, CWN-352, CWN-551, or CWN-552 series based on hook length requirements.

Frequently Asked Questions (FAQ)

Q: Can I use CW Industries CWN-360 series as a direct replacement for the 3M 3314-6002UG?

A: CWN-360 series maintains all critical parameters: 14 positions, 2 rows, 2.54mm pitch, through-hole mounting, shrouded 4-wall design, and Push-Pull fastening. However, the contact shape differs (circular versus square), which may affect insertion force and mating characteristics. Verify compatibility with the mating connector before implementation.

Q: What is the difference between CWN-360-14-0000 and CWN-360-14-0021?

A: Both parts are electrically and mechanically identical. The difference lies in contact finish thickness on the mating surface: CWN-360-14-0000 has 10.0µin (0.25µm) gold plating, while CWN-360-14-0021 has 30.0µin (0.76µm) gold plating. The thicker plating in the -0021 variant provides enhanced durability for high-cycle mating applications.

Q: Why should I choose N3314-6002RB over the original 3314-6002UG?

A: The N3314-6002RB is an active product with RoHS compliance, whereas the 3314-6002UG is obsolete and non-compliant. The N3314-6002RB offers higher current rating (1.75A versus 1A) and improved material composition (PCT insulation). It maintains the same connector geometry and fastening mechanism, ensuring compatibility with existing mating connectors.

Q: What is the difference between Latch Lock/Eject Hooks, Short and Long?

A: Both variants employ latch-lock fastening for secure mating. The "Short" variant (CWN-351, CWN-551) provides standard hook engagement, while the "Long" variant (CWN-352, CWN-552) extends the hook length for enhanced retention force. Selection depends on application requirements for mating force and disconnection security.

Q: Are all substitute parts rated for the same operating temperature range?

A: No. The original 3M parts (3314-6002UG, 3314-6002, N3314-6002RB) are rated -55°C ~ 105°C. All CW Industries substitutes (CWN series) are rated -55°C ~ 125°C, providing extended high-temperature capability.

Q: What is the significance of the contact post length variation?

A: Contact post length determines the depth of insertion into the PCB. CWN-360 and CWN-361 series with 0.155" (3.94mm) posts are suitable for standard PCB thicknesses. CWN-351, CWN-352, CWN-551, and CWN-552 series with 0.090" (2.29mm) posts are designed for thinner PCB applications or when reduced insertion depth is required. Verify PCB thickness compatibility before selection.

Q: Do all substitute parts have the same current rating?

A: No. The original 3314-6002UG and most substitutes are rated 1A. The N3314-6002RB offers enhanced current rating of 1.75A. For applications requiring higher current capacity, N3314-6002RB is the appropriate selection.

Q: What does RoHS compliance mean for connector selection?

A: RoHS compliance indicates the part meets Restriction of Hazardous Substances regulations, eliminating lead and other restricted materials from the manufacturing process. The original 3314-6002UG is non-compliant. All active substitutes (N3314-6002RB and CW Industries CWN series) are RoHS compliant or ROHS3 compliant, meeting current regulatory requirements for new designs and procurement.
