The 2×5×7mm rectangular through-hole LED is one of the quiet heroes of modern product design — a 0.06W indicator lamp that hides behind a slim panel window yet throws a bright, evenly diffused rectangle of light. For buyers sourcing status indicators in volume, the BOSMFC 2*5*7mm through hole LED gives seven colors, an 80–160° viewing angle and a 60,000-hour rating from a single footprint.
Why the Rectangular 2×5×7mm Format Wins in Panel Design
A round 3mm or 5mm lamp leaves a circular hot spot behind an injection-moulded window. The rectangular body solves that geometry problem directly: the emitting face matches the shape of the indicator window, so the lit area looks intentional instead of accidental.
- Rectangular emitting face — fills panel cut-outs edge to edge with no hot spot or dark corner.
- Wide 80–160° beam — comfortable viewing from steep angles on wall-mounted equipment.
- Low 0.06W drive — 20mA at 1.8–3.6V, easy to run from 5V, 12V or 24V rails.
- Two-lead through-hole mounting — hand or wave soldering, no reflow profile needed.
- San'an / Epistar chips — consistent brightness bins across production lots.
Seven Light Colors From One Footprint
Instead of stocking seven part numbers, panel makers can standardise on one housing and switch the bin. The table below shows the measured range of the platform at IF=20mA, Ta=25°C.

Five Application Scenarios That Fit This Part
| Scenario |
Why the 2×5×7mm LED Fits |
| Industrial control panels & switchgear |
Rectangular lens maps onto DIN-rail status windows; 20mA drive suits 24V control rails with a single series resistor. |
| Power strips, sockets & chargers |
Low power consumption (0.06W) keeps standby draw negligible; green and red bins share one mounting hole. |
| Home appliance front panels |
Uniform rectangle reads clearly through tinted PC windows on air fryers, purifiers and coffee machines. |
| Networking & audio equipment |
Blue and yellow-green bins give link, activity and standby states with identical mechanical design. |
| Elevator, vending & POS terminals |
Two-lead body survives vibration and repeated assembly far better than bare SMD chips under a light guide. |
Design Notes: Current Limiting at a Glance
Each lamp needs only one series resistor. The values below keep the part at 20mA on the three rails most common in panel electronics.
| Color group |
5V rail |
12V rail |
24V rail |
| Red / Yellow / Yellow-green / Orange |
150Ω |
510Ω |
1.1kΩ |
| Green / Blue / White |
100Ω |
470Ω |
1kΩ |
Mounting tip: keep the 0.3–1mm air gap between lamp face and panel window below 2mm and add a matte diffuser film if the customer requires a perfectly flat glow.
Quality and Supply Behind the Part
The lamp is produced by Dongguan Lanjin Optoelectronics Co., Ltd. (东莞市蓝晋光电有限公司), an LED manufacturer established in 2005 with a 2,500m² anti-static, constant-temperature workshop in Dongguan, China.
