Engineering Selection Recommendations

Primary Selection - CWN-562-14-0021 (CW Industries)

The CWN-562-14-0021 remains the preferred choice for new designs and ongoing production. It is actively manufactured, ROHS3 compliant, and supports the full operating temperature range of -55°C to 125°C. The part offers the highest temperature capability among all listed options and maintains active product status with adequate inventory.

Active Substitute - N3314-6002RB (3M)

The N3314-6002RB is the primary active substitute. It is RoHS compliant, currently in production, and provides higher current rating (1.75A vs. 1A). The operating temperature range is -55°C to 105°C, which is acceptable for applications not requiring the extended upper temperature limit of the primary part. This part offers the largest inventory availability (2110 units).

Active Substitute - N3314-6003RB (3M)

The N3314-6003RB is functionally equivalent to N3314-6002RB with identical electrical and compliance specifications. The primary difference is the contact post length (0.155" vs. 0.112"), which may be required for specific PCB thickness or assembly configurations. This part is RoHS compliant and actively manufactured.

Active Substitute - 71918-014LF (Amphenol ICC)

The 71918-014LF (Quickie™ series) is an active substitute with RoHS compliance and the highest inventory availability (1472 units). Operating temperature range is not specified in available documentation. This part features GXT™ gold plating on mating contacts and tin post finish. Current rating is not specified.

Obsolete Substitute - 3314-6002 (3M)

The 3314-6002 is obsolete and RoHS non-compliant. This part should not be selected for new designs or applications requiring RoHS compliance. It is retained in this reference only for legacy system support and reverse engineering purposes.

Frequently Asked Questions (FAQ)

Q: Can N3314-6002RB be used as a direct replacement for CWN-562-14-0021?

A: Yes, for applications where the operating temperature range of -55°C to 105°C is acceptable. The N3314-6002RB meets all critical mechanical and electrical parameters: 14 positions, 2 rows, 0.100" pitch, through-hole solder termination, shrouded 4-wall construction, and UL94 V-0 flammability rating. The higher current rating (1.75A) provides additional margin. Both parts are RoHS compliant and MSL 1.

Q: What is the difference between N3314-6002RB and N3314-6003RB?

A: Both parts are electrically and mechanically equivalent with identical pitch, position count, and compliance specifications. The primary difference is contact post length: N3314-6002RB has 0.112" (2.84mm) post length, while N3314-6003RB has 0.155" (3.94mm) post length. Selection depends on PCB thickness and assembly requirements. Overall contact length differs accordingly (0.652" vs. 0.695").

Q: Why is 3314-6002 listed if it is obsolete?

A: The 3314-6002 is included for reference in legacy system documentation and reverse engineering applications. It should not be selected for new designs. The part is RoHS non-compliant and no longer actively manufactured. Use N3314-6002RB or N3314-6003RB as active alternatives.

Q: Does operating temperature range affect substitution eligibility?

A: Operating temperature range is a design consideration but does not preclude substitution. The CWN-562-14-0021 supports -55°C to 125°C, while N3314-6002RB and N3314-6003RB support -55°C to 105°C. Applications operating above 105°C require the primary part or equivalent with extended temperature rating. Applications within -55°C to 105°C range can use either part.

Q: Are contact finish differences significant for substitution?

A: Contact finish differences (gold, tin, tin-lead, nickel) do not preclude substitution when mating contact materials are compatible. All listed parts feature gold mating contact finish. Post finish variations (nickel, tin, tin-lead) affect solder joint characteristics and long-term reliability in specific environments but do not prevent mechanical or electrical substitution in standard applications.

Q: What is the inventory status for each part?

A: CWN-562-14-0021: 879 units; N3314-6002RB: 2110 units; N3314-6003RB: 1015 units; 71918-014LF: 1472 units; 3314-6002: 654 units (obsolete). N3314-6002RB offers the highest availability among active parts.

Q: Are all substitute parts RoHS compliant?

A: No. The 3314-6002 is RoHS non-compliant and obsolete. All other listed parts (CWN-562-14-0021, N3314-6002RB, N3314-6003RB, 71918-014LF) are RoHS compliant. For applications requiring RoHS compliance, exclude 3314-6002 from consideration.

Q: What packaging formats are available?

A: CWN-562-14-0021: Packaging not specified; 3314-6002: Bulk; 71918-014LF: Tube; N3314-6002RB: Bulk; N3314-6003RB: Bulk. Packaging format may affect handling, storage, and assembly line integration requirements.
