Part Overview
The FRB2S1015 is a glass body reed switch manufactured by Coto Technology, configured as a single-pole single-throw normally open (SPST-NO) device. This component operates within a 10–15 ampere-turn (AT) magnetic operate range and switches up to 500 mA at 200 V across both AC and DC applications, with a rated power capacity of 10 VA. The device features surface mount termination with axial flat leads and operates across an industrial temperature range of –40°C to 125°C.
The FRB2S1015 is classified as obsolete. Locating equivalent substitute parts is necessary to support ongoing maintenance, repair, and new design requirements where this component is specified or currently deployed.

Engineering Selection Recommendations
MDSR-10-10-15 (Littelfuse)
The MDSR-10-10-15 is an active product that meets the core electrical requirements of the FRB2S1015 for DC switching applications at 200 V and 500 mA. This part maintains the same operate range (10–15 AT), operating temperature span (–40°C to 125°C), and power rating (10 W). The MDSR-10-10-15 achieves ROHS3 compliance and carries REACH unaffected status, meeting current regulatory requirements.
Substitution constraints: The MDSR-10-10-15 is rated for 350 mA AC switching at 140 V AC, which is below the FRB2S1015 specification of 500 mA at 200 V AC. This part is suitable for DC-only applications or AC applications within its 140 V AC / 350 mA rating. The through-hole mounting configuration requires circuit board redesign compared to the surface mount FRB2S1015.
ORD 324/10-15 AT (Standex-Meder Electronics)
The ORD 324/10-15 AT is an active product that matches the FRB2S1015 for DC switching at 500 mA and 200 V. This part maintains the 10–15 AT operate range, –40°C to 125°C temperature range, and 10 W power rating. The ORD 324/10-15 AT achieves ROHS3 compliance and carries REACH unaffected status.
Substitution constraints: AC switching voltage and current specifications are not provided for the ORD 324/10-15 AT. This part is confirmed suitable for DC applications. The through-hole mounting configuration requires circuit board redesign compared to the surface mount FRB2S1015.
Regulatory and Compliance Status
Both substitute parts exceed the regulatory compliance profile of the obsolete FRB2S1015. The MDSR-10-10-15 and ORD 324/10-15 AT both carry ROHS3 certification and REACH unaffected status, supporting deployment in applications subject to current environmental and hazardous substance restrictions.
Frequently Asked Questions (FAQ)
Q: Can the MDSR-10-10-15 replace the FRB2S1015 in all applications?
A: The MDSR-10-10-15 is suitable for DC applications and AC applications within its rated limits of 350 mA at 140 V AC. If the original application requires 500 mA at 200 V AC, the MDSR-10-10-15 does not meet this specification. For DC-only or lower AC voltage/current applications, the MDSR-10-10-15 is electrically compatible.
Q: What is the impact of switching from surface mount to through-hole mounting?
A: The FRB2S1015 uses surface mount termination with axial flat leads, while both substitute parts (MDSR-10-10-15 and ORD 324/10-15 AT) use through-hole axial termination. This requires modification to the circuit board layout, including drilling holes and repositioning component placement. Electrical function remains unchanged.
Q: Are both substitute parts compliant with current environmental regulations?
A: Yes. Both the MDSR-10-10-15 and ORD 324/10-15 AT carry ROHS3 compliance and REACH unaffected status, meeting current environmental and hazardous substance regulations applicable to electronic components.
Q: What are the key differences in switching performance between these parts?
A: The FRB2S1015 and both substitutes share identical operate times of 0.5 ms. Release times differ: the FRB2S1015 releases in 0.2 ms, the MDSR-10-10-15 in 0.1 ms, and the ORD 324/10-15 AT in 0.05 ms. Faster release times in the substitute parts may improve circuit response characteristics in applications sensitive to switch release delay.
Q: Which substitute part should be selected for a new design?
A: For DC applications at 500 mA and 200 V, both the MDSR-10-10-15 and ORD 324/10-15 AT are electrically equivalent. Selection depends on circuit board layout constraints and availability. For AC applications requiring 500 mA at 200 V, neither substitute meets the full specification of the FRB2S1015.
Q: What is the operating temperature compatibility?
A: All three parts (FRB2S1015, MDSR-10-10-15, and ORD 324/10-15 AT) operate across the identical temperature range of –40°C to 125°C, ensuring thermal compatibility in industrial and extended-temperature applications.
