Substitute Part Grouping Explanation

Substitution for the 3314-6002 is determined by strict equivalence across the following critical parameters:

Connector type (Header), contact type (Male Pin), and mating interface (14 positions, 2 rows, 2.54mm pitch)
Mounting method (Through Hole) and termination type (Solder)
Shrouding configuration (Shrouded - 4 Wall) and fastening mechanism
Operating temperature range and flammability rating (UL94 V-0)
Physical compatibility: insulation height, contact length, and overall dimensions

Substitute parts are grouped into two categories:

Direct Manufacturer Equivalent: N3314-6002RB (3M) — Active product with identical electrical and mechanical specifications, upgraded to RoHS Compliant status with improved current rating (1.75A vs. 1A).

Cross-Manufacturer Alternatives: Parts from Amphenol ICC (FCI) and CW Industries that maintain core functional compatibility while introducing variations in contact material, finish specifications, fastening mechanisms, or post length. These alternatives are suitable where design flexibility permits accommodation of minor dimensional or material differences.

Engineering Selection Recommendations

N3314-6002RB (3M) is the primary direct equivalent for the obsolete 3314-6002. This part maintains identical mechanical and electrical interface specifications while offering active product status, RoHS compliance, and improved current rating (1.75A). The insulation material upgrade from PBT to PCT and contact finish change from Tin-Lead to Tin align with modern manufacturing standards. This part is recommended for direct replacement in new designs and legacy system updates.

71918-014LF (Amphenol ICC/FCI) provides cross-manufacturer compatibility with active product status and RoHS compliance. Minor variations include contact material (Phosphor Bronze vs. Copper Alloy), mating contact length (0.228" vs. 0.240"), and insulation material composition. The Quickie™ series designation indicates optimized manufacturing. This part is suitable where multi-source qualification is required.

CWN-360-14-0000 and CWN-360-14-0021 (CW Industries) offer extended operating temperature range (-55°C ~ 125°C vs. -55°C ~ 105°C) with ROHS3 compliance. Both variants feature circular contact geometry and Phosphor Bronze material. The primary difference is contact finish thickness on the mating surface (10.0µin vs. 30.0µin). CWN-360-14-0021 with standard gold plating thickness is preferred for general applications.

CWN-550-14-0021 (CW Industries) maintains push-pull fastening with reduced post length (0.090" vs. 0.112"), suitable for applications with space constraints. Extended temperature rating and ROHS3 compliance are provided.

Parts with alternative fastening mechanisms (Latch Lock/Eject Hooks) such as CWN-351-14-0021, CWN-352-14-0021, CWN-361-14-0000, CWN-551-14-0000, and CWN-551-14-0021 are functionally equivalent but require mating connector redesign and are not recommended as direct substitutes without design review.

Frequently Asked Questions (FAQ)

Q: Can N3314-6002RB be used as a direct replacement for 3314-6002?

A: Yes. N3314-6002RB maintains identical mating interface specifications (14 positions, 2.54mm pitch, 2 rows), mounting method (through-hole), termination (solder), shrouding (4-wall), and fastening (push-pull). The part is mechanically and electrically compatible. Differences in insulation material (PCT vs. PBT) and contact finish (Tin vs. Tin-Lead) represent manufacturing improvements aligned with current standards.

Q: What are the key differences between 3M and CW Industries alternatives?

A: 3M N3314-6002RB maintains the original contact geometry (square) and material (Copper Alloy). CW Industries parts (CWN series) use Phosphor Bronze contacts with circular geometry. Contact post length varies across CW offerings (0.090" to 0.155"), affecting PCB stack-up compatibility. All maintain 2.54mm pitch and 14-position configuration.

Q: Are CWN parts with different fastening types compatible?

A: CWN parts with Latch Lock/Eject Hooks fastening (CWN-351, CWN-352, CWN-361, CWN-551 series) are not direct substitutes. These require mating connectors with corresponding hook engagement features. Push-pull fastening variants (CWN-360, CWN-550) maintain compatibility with standard 2.54mm pitch mating connectors.

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

A: Contact post length affects PCB solder joint depth and stack-up clearance. The 3314-6002 and N3314-6002RB specify 0.112" (2.84mm) post length. CWN-360 and CWN-361 variants provide 0.155" (3.94mm) for deeper PCB penetration. CWN-550 and CWN-551 variants provide 0.090" (2.29mm) for shallow mounting. Post length selection depends on PCB thickness and solder joint requirements.

Q: Does RoHS compliance affect electrical performance?

A: RoHS compliance in these parts reflects material composition changes (elimination of lead in contact finishes) rather than electrical performance degradation. All substitute parts maintain equivalent current ratings or higher (1A minimum, up to 1.75A for N3314-6002RB) and operating temperature ranges (-55°C ~ 105°C minimum, up to -55°C ~ 125°C for CW Industries parts).

Q: What packaging options are available?

A: 3314-6002 and most substitutes are supplied in Bulk packaging. 71918-014LF (Amphenol ICC) is supplied in Tube packaging. Packaging selection does not affect connector functionality but may impact procurement and handling procedures.

Q: Can 71918-014LF be used where 3314-6002 was specified?

A: Yes, with design verification. 71918-014LF maintains core compatibility (14 positions, 2.54mm pitch, through-hole, solder termination, push-pull fastening, 4-wall shrouding). Differences include Phosphor Bronze contacts (vs. Copper Alloy), mating contact length (0.228" vs. 0.240"), and thermoplastic insulation material. These variations are within acceptable tolerance for standard applications but should be confirmed against specific design requirements.
