3M 3314-2002 Rectangular Connector Header - Equivalent & Substitute Parts

Part Overview

The 3M 3314-2002 is a through-hole rectangular connector header with 14 positions arranged in 2 rows at 0.100" (2.54mm) pitch. This connector is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing design support and procurement. The part features shrouded 3-wall construction, gold-plated mating contacts, and tin-lead plated posts, with a current rating of 1.75A and operating temperature range of -55°C to 105°C.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 3M 3314-2002 is determined by the following critical parameters:

• Connector type, contact type, and pin count (14 positions, 2 rows)
• Mating pitch and row spacing (0.100" / 2.54mm)
• Mounting method (through-hole solder termination)
• Fastening mechanism (push-pull)
• Shrouding configuration (shrouded design with keying slot)
• Operating temperature range (-55°C ~ 105°C minimum)
• Current rating (minimum 1.75A)
• Flammability rating (UL94 V-0)

The substitute parts listed maintain these core electrical and mechanical parameters. Variations in insulation material, contact finish composition, shrouding wall count, and compliance certifications are noted but do not prevent functional substitution when application requirements permit.

Parameter Comparison

Engineering Selection Recommendations

3M 3314-6002: This part maintains identical mechanical and electrical specifications to the main part, including the 1.75A current rating and -55°C to 105°C operating range. The primary difference is the 4-wall shrouding versus 3-wall on the original. Both parts share obsolete product status and RoHS non-compliance. Selection is appropriate for applications where existing inventory or legacy design compatibility is prioritized.

3M N3314-6002RB: This is the active-status equivalent within the 3M 3000 series. It matches the 1.75A current rating and operating temperature range of the original part. The contact post finish differs (tin versus tin-lead), and the part is RoHS compliant. This part is recommended for new designs or ongoing procurement where active product status and regulatory compliance are required.

CW Industries CWN-350-14-0021: This alternative from CW Industries maintains the core 14-position, 2-row, 0.100" pitch configuration and push-pull fastening. It offers an extended operating temperature range (-55°C to 125°C) and RoHS3 compliance. The current rating is reduced to 1A, and the contact post length is shorter (0.090" versus 0.112"). This part is suitable for applications where the lower current rating is acceptable and extended temperature performance is beneficial.

Frequently Asked Questions (FAQ)

Q: Can the 3314-6002 be used as a direct replacement for the 3314-2002?

A: Yes, from an electrical and mechanical standpoint. Both parts share identical pitch, position count, current rating (1.75A), and operating temperature range. The 4-wall shrouding on the 3314-6002 provides enhanced mechanical protection compared to the 3-wall design of the original. Both parts are obsolete and RoHS non-compliant.

Q: What is the advantage of selecting N3314-6002RB over the other substitutes?

A: The N3314-6002RB maintains active product status, ensuring ongoing availability and support. It preserves the 1.75A current rating and -55°C to 105°C operating range of the original part. It is RoHS compliant, meeting modern regulatory requirements. This part is the preferred choice for new designs or applications requiring current product support.

Q: Can the CWN-350-14-0021 be used if the application requires 1.75A current?

A: No. The CWN-350-14-0021 is rated for 1A maximum current, which is below the 1.75A requirement of the original part. This substitute is suitable only for applications with current requirements of 1A or less.

Q: Are there mechanical compatibility concerns with the CWN-350-14-0021?

A: The CWN-350-14-0021 has a shorter contact post length (0.090" versus 0.112") and circular contact geometry instead of square. These differences may affect mating force, insertion depth, and mechanical fit with existing mating connectors. Physical validation is necessary before deployment in existing designs.

Q: What is the significance of the shrouding wall count difference?

A: The 3-wall shrouding on the original 3314-2002 provides basic keying and mechanical guidance. The 4-wall shrouding on the 3314-6002 and N3314-6002RB offers enhanced mechanical protection and improved alignment during mating. Both configurations maintain the same electrical performance and are mechanically compatible with standard 0.100" pitch mating connectors.

Q: Does RoHS compliance affect electrical performance?

A: No. RoHS compliance relates to material composition (elimination of lead and other restricted substances) and does not alter electrical characteristics. The N3314-6002RB and CWN-350-14-0021 are RoHS compliant alternatives that maintain the same electrical performance as the non-compliant original part.

Q: What is the difference between tin-lead and tin post finishes?

A: Both finishes provide adequate solder wettability for through-hole termination. Tin-lead (the original finish) has been widely used in legacy designs. Tin (used on N3314-6002RB) is the modern alternative that complies with RoHS restrictions on lead content. From a functional standpoint, both are suitable for solder termination.
