3M 3314-1302 Rectangular Connector Header - Equivalent & Substitute Parts

Part Overview

The 3M 3314-1302 is a through-hole, right-angle rectangular connector header with 14 positions at 2.54mm pitch. This component is classified as obsolete, making equivalent substitute parts necessary for new designs and ongoing production requirements. The connector features shrouded construction with latch lock/eject hooks and is suitable for board-to-cable/wire applications requiring reliable solder termination.

Substitute Part Grouping Explanation

Substitution eligibility for the 3M 3314-1302 is determined by the following critical parameters:

Connector Type & Contact Configuration: Header with male pins
Position Count & Arrangement: 14 positions in 2-row configuration
Pitch Specification: 0.100" (2.54mm) mating pitch and row spacing
Mounting & Orientation: Through-hole, right-angle mounting
Electrical Performance: 1.75A current rating and -55°C to 105°C operating range
Safety Compliance: UL94 V-0 flammability rating

The substitute parts D3314-5002-AR and N3314-5002RB maintain these core electrical and mechanical parameters. Variations in shrouding wall count (3-wall vs. 4-wall), fastening mechanism (latch lock vs. push-pull), contact material composition, and RoHS compliance status do not affect functional interchangeability within the specified parameter envelope.

Engineering Selection Recommendations

Both D3314-5002-AR and N3314-5002RB are active production alternatives to the obsolete 3314-1302. Selection between these substitutes should be based on the following criteria:

D3314-5002-AR is recommended for applications requiring RoHS compliance with active product support. This part features 4-wall shrouding and push-pull fastening, with packaging in trays suitable for automated assembly processes.

N3314-5002RB is recommended for applications where bulk packaging is preferred and RoHS compliance is required. This part also features 4-wall shrouding and push-pull fastening, maintaining electrical and mechanical compatibility with the original specification.

Both substitute parts maintain the core electrical performance (1.75A current rating, -55°C to 105°C operating range) and safety certifications (UL94 V-0) of the original component. The transition from the obsolete 3314-1302 to either active substitute ensures continued product availability and compliance with current regulatory standards.

Frequently Asked Questions (FAQ)

Q: Can D3314-5002-AR and N3314-5002RB be used interchangeably with 3314-1302?

A: Yes. Both substitute parts maintain identical electrical and mechanical parameters including 14-position configuration, 2.54mm pitch, through-hole right-angle mounting, 1.75A current rating, and -55°C to 105°C operating temperature range. The core connector interface is functionally equivalent.

Q: What are the differences between D3314-5002-AR and N3314-5002RB?

A: The primary differences are packaging format (D3314-5002-AR ships in trays; N3314-5002RB ships in bulk) and contact material composition (D3314-5002-AR uses brass; N3314-5002RB uses copper alloy). Both maintain identical electrical performance and mechanical dimensions.

Q: Why is the original 3314-1302 obsolete?

A: The 3314-1302 has been superseded by active production alternatives. The substitute parts D3314-5002-AR and N3314-5002RB offer improved compliance status and continued manufacturing support.

Q: Are the substitute parts RoHS compliant?

A: Yes. Both D3314-5002-AR and N3314-5002RB are RoHS compliant, whereas the original 3314-1302 is RoHS non-compliant.

Q: Do the substitute parts have different shrouding specifications?

A: The original 3314-1302 features 3-wall shrouding, while both substitutes (D3314-5002-AR and N3314-5002RB) feature 4-wall shrouding. This provides enhanced mechanical protection without affecting electrical interchangeability.

Q: What fastening mechanisms are used in the substitute parts?

A: Both D3314-5002-AR and N3314-5002RB use push-pull fastening, compared to the latch lock/eject hooks used in the original 3314-1302. Both mechanisms provide secure mating and are suitable for board-to-cable/wire applications.
