Overview
The Citizen CL-270S-WS-SD is a white side-view light-emitting diode designed for surface-mount applications. It features a right-angle configuration within a compact 2-SMD, no-lead package measuring 1.60mm in length, 1.15mm in width, and a maximum height of 0.60mm. The component operates at a forward voltage of 2.9V DC with a typical current of 5mA, delivering a luminous intensity range of 99 to 190 mcd. It is classified under the CL-270 series and holds RoHS compliance status.
Feature Summary
- Side-view emission geometry optimized for visibility from lateral angles
- Compact surface-mount footprint suitable for space-constrained designs
- Right-angle mounting orientation for flexible PCB layout integration
Applications
- Indicator lighting for wristwatches and timepieces
- Status indication in portable consumer electronics
- LED-based signage systems requiring low-profile components
Procurement Notes
Verify component availability carefully as this part is listed as obsolete or end-of-life with an expiration date noted in March 2025. Confirm final stock levels with authorized distributors before committing to production schedules. Ensure that any substitute components meet identical dimensional and electrical specifications to maintain design integrity without requiring board modifications.
Selection Notes
Select this component when a white side-view indicator is required for slim profile devices. The specific angular emission pattern distinguishes it from top-view alternatives. Verify that the 2.9V forward voltage aligns with the system power supply constraints. Consider the moisture sensitivity level (MSL 3) during storage and handling procedures to prevent package damage prior to soldering.
Part Context
This device belongs to the CL-270 series of discrete LED indicators manufactured by Citizen Electronics. The series offers various color options including green and yellow variants, all sharing similar physical dimensions and surface-mount characteristics. The CL-270S-WS-SD specifically provides white illumination with a side-view characteristic, differentiating it from standard top-emitting models within the same product family.
Replacement Considerations
Public confirmed substitute part numbers include CL-270S-WS-SD-TS. Verify compatibility regarding packaging format and exact luminous intensity ranges before substitution.
