[Information Presentation] A must-see for those struggling with discontinued resistors! Support for resistor alternatives.

Are you prepared for risks such as discontinued products or halted production and supply? We support alternatives for resistors! We achieve a system that accommodates a wide variety of small lots and short delivery times!

This document is a reference compatibility guide for resistors to support the substitution of resistors. It is important to hedge risks in case of discontinuation of existing products or supply interruptions due to various reasons. When the supply sources are concentrated in specific countries or factories, there is a possibility of significant delays in delivery if an "unexpected" situation occurs. This document includes carbon film fixed resistors, wire-wound fixed resistors, and cement case film fixed resistors, among others. While it does not guarantee individual characteristics as equivalent products, it can be useful for considering compatibility based on basic specifications and sizes. Our company possesses core technologies such as high-precision and reliable spot welding, as well as the encapsulation of composite components using non-flammable silicone-based cement. We have a track record of adoption in various fields, including consumer electronics, industrial equipment, and gaming machines, but please inquire about individual characteristics. [Contents (partial)] ■ Background ■ Resistor Reference Compatibility Table ■ Carbon Film Fixed Resistor 0Ω Series "RD Type" ■ Non-Flammable Carbon Film Fixed Resistor "FRD Type" ■ Non-Flammable Coating Film Fixed Resistor "RG/RX Type" *For more details, please refer to the PDF document or feel free to contact us.

[For those who are not satisfied with generic products] A proposal for customized resistors.

We respond to customization requests that are not satisfied with catalog items! This can save you the hassle of post-processing after arrival.

At Riku Electric Co., Ltd., we offer "customization of resistors." Due to the configuration of the equipment or the layout of the circuit board, standard catalog products may not meet your specifications, sizes, or shapes. We will align your requirements and provide feasible proposals. We solve issues where customization is necessary because the sizes and shapes of catalog items do not match the design specifications. We eliminate the hassle of post-processing that you may be doing on your end. 【Product Examples】 We customize terminal shapes, sizes, specifications, etc., for various general-purpose resistors. Whether you want to change the shape of the mounting terminals, extend the length of the lead wires, modify the case size, or require a special combination of power and resistance values, we will provide feasible proposals. ■ Carbon film fixed resistors ■ Metal film fixed resistors ■ Metal glaze film fixed resistors ■ Flame-retardant coated fixed resistors ■ Wire-wound fixed resistors ■ Cement case fixed resistors *For more details, please download the PDF or feel free to contact us.
