3M 3314-2202 Rectangular Connector Header - Equivalent & Substitute Parts

Part Overview

The 3M 3314-2202 is a through-hole rectangular connector header with 14 positions arranged in 2 rows at 0.100" (2.54mm) pitch. This component is classified as obsolete, making equivalent substitute parts necessary for ongoing design support and procurement. The connector features shrouded 3-wall construction with solder termination and latch lock/eject hook fastening. Substitutes must maintain electrical and mechanical compatibility while meeting current availability and compliance requirements.

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following critical parameters:

Connector Type & Contact Configuration: Header with male pins, 14 positions in 2 rows
Pitch Specification: 0.100" (2.54mm) mating pitch and row spacing
Mounting & Termination: Through-hole solder termination
Contact Dimensions: Mating contact length 0.240" (6.10mm) and post length 0.112" (2.84mm) define mechanical fit
Electrical Rating: Current capacity of 1.75A

Engineering Selection Recommendations

For RoHS Compliance Requirements:

N3314-6002RB is the direct 3M equivalent with RoHS Compliant status and active product availability. This part maintains identical electrical and mechanical specifications to the 3314-2202 while providing current procurement support. The contact post finish changes from tin-lead to tin, which is compatible with modern solder processes.

For Extended Temperature Range Applications:

HARTING SEK series parts (09185145902, 09185145904, 09185146902, 09185146904, 09185147902, 09185147904, 09195145904) offer operating temperature to -55°C ~ 125°C, exceeding the original 3314-2202 specification of -55°C ~ 105°C. These parts carry ROHS3 Compliant and REACH Unaffected certifications. Contact post lengths vary between 0.114" (2.90mm) and 0.177" (4.50mm), requiring PCB design verification for through-hole depth compatibility.

For Mechanical Fit Considerations:

Part 09185145329 features a significantly reduced insulation height of 0.350" (8.89mm) compared to the 0.680" (17.27mm) standard, and offers press-fit termination as an alternative to solder-only. This configuration is suitable only for applications with specific board-to-board spacing constraints.

For Current Availability:

All HARTING SEK series parts maintain active product status with inventory levels between 887 and 1,421 pieces. The 3M N3314-6002RB variant provides 2,110 pieces in stock, offering the highest availability for immediate procurement needs.

Frequently Asked Questions (FAQ)

Q: Can HARTING SEK series parts directly replace the 3M 3314-2202 in existing designs?

A: HARTING parts maintain the same 14-position, 2-row configuration at 0.100" (2.54mm) pitch and through-hole solder termination. However, contact post length variations (0.114" to 0.217" versus the original 0.112") require verification of PCB hole depth and via placement. Fastening mechanism differences (latch lock/eject hooks versus the original latch lock/eject hooks, short) may affect mating force characteristics.

Q: What is the difference between 3314-6002 and N3314-6002RB?

A: Both are 3M parts with identical electrical and mechanical specifications. The primary differences are: N3314-6002RB is active product status versus obsolete for 3314-6002; N3314-6002RB carries RoHS Compliant certification; contact post finish is tin versus tin-lead. The N3314-6002RB is the recommended 3M substitute for new designs.

Q: Are there current rating differences among substitute parts?

A: The original 3314-2202 specifies 1.75A current rating. The 3M 3314-6002 maintains this rating at 1A. HARTING SEK series parts do not provide current rating specifications in available documentation. Design verification is required for applications approaching the 1.75A threshold.

Q: What packaging options are available?

A: 3M parts are supplied in bulk packaging. HARTING 09185147904 is supplied in tray packaging; all other HARTING variants use bulk packaging. Packaging selection affects procurement logistics and component handling procedures.

Q: Do all substitute parts meet the same environmental compliance standards?

A: All parts carry UL94 V-0 flammability rating and MSL 1 (Unlimited) moisture sensitivity. RoHS compliance differs: 3314-2202 and 3314-6002 are non-compliant; N3314-6002RB, all HARTING parts are ROHS3 Compliant. HARTING parts additionally carry REACH Unaffected certification.
