3M N3314-6203RB Equivalent & Substitute Parts

Part Overview

The 3M N3314-6203RB is a shrouded rectangular connector header for through-hole mounting with 14 positions arranged in 2 rows at 0.100" (2.54mm) pitch. This connector is designed for board-to-cable/wire applications with solder termination and latch lock/eject hook fastening. The part is active in production and RoHS compliant, making it suitable for modern electronic assemblies requiring reliable interconnection in standard pitch configurations.

Engineering Selection Recommendations

All listed substitute parts maintain active product status and comply with RoHS requirements. Selection among qualified alternatives should be based on the following considerations:

3M N3314-6202RB: Direct 3M alternative within the same 3000 series. Maintains identical pitch, position count, and row spacing. Differs only in contact post length (0.112" versus 0.155"), which remains within acceptable mechanical tolerance ranges for standard through-hole PCB applications. Recommended when 3M supply chain continuity is prioritized.

HARTING SEK Series (09185145904, 09185146902, 09185146904, 09185146914, 09185147902, 09185147904, 09185147914): All HARTING alternatives maintain full electrical and mechanical compatibility. These parts offer extended operating temperature range (-55°C to 125°C versus -55°C to 105°C) and ROHS3 compliance. Variations in contact length and fastening type (Short versus Long hooks) accommodate different PCB thickness and mating force requirements. Tray packaging options (09185147904, 09185147914) provide alternative handling for high-volume assembly operations.

HARTING 09195146904: Maintains SEK series compatibility with PCT insulation material and extended temperature range. Contact finish specification is not provided; confirmation with manufacturer is necessary for applications requiring specific mating surface characteristics.

TE Connectivity 5499160-2: AMP-Latch series alternative with identical mating contact length and gold/gold-palladium finish options. Insulation height is reduced (0.549" versus 0.680"), which may affect mechanical fit in applications with height-constrained PCB layouts. Current rating specified at 1A (versus 1.75A for N3314-6203RB). Tray packaging format supports automated assembly processes.

Frequently Asked Questions (FAQ)

Q: Can I substitute the 3M N3314-6203RB with any of the HARTING SEK series connectors?

A: Yes. All HARTING SEK series parts listed (09185145904, 09185146902, 09185146904, 09185146914, 09185147902, 09185147904, 09185147914) maintain the required 14-position, 2-row configuration at 0.100" pitch with shrouded 4-wall design and solder termination. Variations in contact length and fastening hook style remain within acceptable mechanical tolerances for standard through-hole applications.

Q: What is the difference between Short and Long fastening hooks?

A: Fastening hook length affects the mating force and retention characteristics. Short hooks (as in N3314-6203RB and 09185146914) provide standard retention for typical PCB thicknesses. Long hooks (09185145904, 09185146902, 09185147902) accommodate thicker or more rigid mating connectors. Selection depends on the specific mating connector and PCB assembly requirements.

Q: Does the contact post length variation affect compatibility?

A: Contact post length variations (0.110" to 0.177") are mechanical design parameters that do not affect electrical compatibility. These variations accommodate different solder joint geometries and PCB thickness requirements. Standard through-hole PCB designs accept the full range of post lengths specified.

Q: Why does the TE Connectivity 5499160-2 have a lower insulation height?

A: The TE Connectivity AMP-Latch series uses a different mechanical design with reduced insulation height (0.549" versus 0.680"). This part remains electrically and functionally compatible but may require verification for applications with height-constrained PCB layouts or specific mechanical mounting requirements.

Q: What is the significance of ROHS3 compliance versus RoHS compliance?

A: Both designations indicate compliance with RoHS directives. ROHS3 represents compliance with the most current RoHS 3 directive (2015/863/EU). All listed parts meet current environmental and material restriction requirements for modern electronic assemblies.

Q: Can I use Bulk packaging parts interchangeably with Tray packaging parts?

A: Yes. Bulk and Tray packaging formats represent different handling and storage methods for the same electrical and mechanical components. Selection between packaging formats depends on assembly process requirements and inventory management practices, not on component compatibility.

Q: What is the current rating difference between N3314-6203RB (1.75A) and 5499160-2 (1A)?

A: The current rating reflects the maximum continuous current the connector contacts can safely carry. The N3314-6203RB supports 1.75A per contact, while the TE Connectivity 5499160-2 supports 1A per contact. For applications requiring current levels between 1A and 1.75A, the N3314-6203RB or equivalent 3M/HARTING alternatives are required.

Q: Are all substitute parts available in the same inventory quantities?

A: Inventory levels vary by part number and supplier. Refer to current stock information for each specific part number when planning procurement. Multiple qualified alternatives ensure supply flexibility when primary part availability is constrained.
