3M 3314-1002 Rectangular Connector Header - Equivalent & Substitute Parts

Part Overview

The 3M 3314-1002 is a through-hole, right-angle rectangular connector header with 14 positions at 0.100" (2.54mm) pitch. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and production continuity. The connector features shrouded 3-wall construction, male pin contacts with gold mating finish, and is rated for -55°C to 105°C operation. Substitute parts maintain core electrical and mechanical compatibility while offering active product status and improved compliance certifications.

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict adherence to the following parameters:

Connector Type & Contact Configuration: All substitutes maintain header connector type with male pin contacts
Position Count & Pitch: All substitutes provide 14 positions at 0.100" (2.54mm) mating pitch with 2-row configuration
Mounting & Termination: All substitutes use through-hole, right-angle mounting with solder termination
Electrical Performance: All substitutes maintain 1.75A current rating and UL94 V-0 flammability rating

Engineering Selection Recommendations

Primary Recommendation: D3314-5002-AR (3M)

The D3314-5002-AR is the manufacturer-recommended substitute from 3M. It maintains identical electrical specifications (1.75A, -55°C to 105°C) and mechanical compatibility while offering active product status and RoHS compliance. The enhanced 4-wall shrouding provides improved mechanical protection compared to the original 3-wall design. Tray packaging supports automated assembly processes.

Secondary Recommendation: N3314-5002RB (3M)

The N3314-5002RB provides equivalent performance with RoHS compliance and active product status. Bulk packaging is suitable for manual assembly or lower-volume applications. Contact material and finish specifications match the original part more closely than D3314-5002-AR.

Alternative Options: 65823-055LF (Amphenol ICC) and CWN-300-14-0021 (CW Industries)

Both alternatives maintain core electrical and mechanical compatibility. The 65823-055LF offers RoHS compliance with tray packaging. The CWN-300-14-0021 supports extended operating temperature range (-55°C to 125°C) and ROHS3 compliance. Contact shape differences (circular vs. square) and fastening type variations (latch lock vs. push-pull) require mechanical design verification.

Compliance Consideration

For applications requiring RoHS compliance, D3314-5002-AR, N3314-5002RB, 65823-055LF, and CWN-300-14-0021 are suitable. The original 3314-1002 and 65823-055 are RoHS non-compliant.

Frequently Asked Questions (FAQ)

Q: Can I directly replace 3314-1002 with any of these substitutes?

A: All listed substitutes maintain the same 14-position, 0.100" (2.54mm) pitch configuration, through-hole right-angle mounting, and solder termination. Mechanical fit and electrical performance are compatible. However, fastening type differences (push-pull vs. latch lock) and contact shape variations (square vs. circular) may require connector housing verification.

Q: What is the difference between 3-wall and 4-wall shrouding?

A: The original 3314-1002 uses 3-wall shrouding, while all substitutes use 4-wall shrouding. The 4-wall design provides enhanced mechanical protection and improved mating force consistency. This change does not affect electrical performance or compatibility with standard 0.100" (2.54mm) pitch connectors.

Q: Are there RoHS-compliant options?

A: Yes. D3314-5002-AR, N3314-5002RB, 65823-055LF, and CWN-300-14-0021 are all RoHS compliant. The original 3314-1002 and 65823-055 are RoHS non-compliant.

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

A: Push-pull fastening (3314-1002, D3314-5002-AR, N3314-5002RB, CWN-300-14-0021) uses friction-based retention. Latch lock/eject hooks (65823-055, 65823-055LF) provide positive mechanical locking with ejector buttons. Selection depends on application requirements for mating force and disconnection control.

Q: Does packaging type affect component performance?

A: No. Tray and bulk packaging are logistics and assembly considerations only. Tray packaging supports automated pick-and-place assembly, while bulk packaging is suitable for manual assembly or lower-volume applications. Electrical and mechanical specifications are identical regardless of packaging.

Q: What is the current rating difference between CWN-300-14-0021 (1A) and other substitutes (1.75A)?

A: The CWN-300-14-0021 is rated for 1A per contact, while the original 3314-1002 and most substitutes are rated for 1.75A. For applications requiring the full 1.75A rating, use D3314-5002-AR, N3314-5002RB, or 65823-055/65823-055LF.

Q: Can I use 65823-055 or 65823-055LF if my design requires RoHS compliance?

A: The 65823-055LF is RoHS compliant and suitable for RoHS applications. The 65823-055 is RoHS non-compliant. Both are functionally equivalent; selection depends on compliance requirements.

Q: What operating temperature range should I specify?

A: The original 3314-1002 and most substitutes support -55°C to 105°C. The CWN-300-14-0021 supports -55°C to 125°C. For applications requiring extended temperature operation, CWN-300-14-0021 is the appropriate selection.
