Engineering Selection Recommendations

All substitute parts maintain active product status and ROHS3 compliance. Selection between substitutes depends on application-specific requirements:

RT0402BRD075K23L and RT0402BRE075K23L offer improved tolerance (±0.1%) within the YAGEO RT series, providing tighter resistance control for precision circuits. RT0402BRD075K23L additionally features reduced temperature coefficient (±25ppm/°C) for enhanced thermal stability.

CPF0402B5K23E1 from TE Connectivity (Neohm series) provides ±0.1% tolerance and ±25ppm/°C temperature coefficient, offering equivalent precision performance with alternative supplier qualification.

ERA-2AEB5231X from Panasonic includes AEC-Q200 automotive qualification, suitable for applications requiring automotive-grade reliability. Maximum seated height is 0.40mm versus 0.35mm for other options; verify PCB clearance before selection.

Frequently Asked Questions (FAQ)

Q: Can RT0402BRD075K23L directly replace RT0402FRE075K23L?

A: Yes. Both parts share identical resistance value (5.23 kOhms), package (0402), power rating (0.063W), and operating temperature range (-55°C to 155°C). RT0402BRD075K23L offers improved tolerance (±0.1% vs ±1%) and lower temperature coefficient (±25ppm/°C vs ±50ppm/°C), making it a direct upgrade for precision applications.

Q: What is the difference between RT0402BRD075K23L and RT0402BRE075K23L?

A: Both parts are YAGEO RT series resistors with ±0.1% tolerance and 0402 package. The primary difference is temperature coefficient: RT0402BRD075K23L has ±25ppm/°C while RT0402BRE075K23L has ±50ppm/°C. Select RT0402BRD075K23L for applications requiring superior thermal stability.

Q: Is ERA-2AEB5231X compatible with standard PCB layouts designed for RT0402FRE075K23L?

A: ERA-2AEB5231X maintains the same 0402 footprint and electrical specifications. However, maximum seated height is 0.40mm compared to 0.35mm for other substitutes. Verify PCB clearance and solder reflow profile compatibility before implementation.

Q: Why would I choose a substitute with ±0.1% tolerance over the original ±1% part?

A: Tighter tolerance (±0.1%) reduces resistance variation across production batches and temperature extremes, improving circuit performance in precision analog applications such as reference networks, gain-setting resistors, and sensor signal conditioning.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts are ROHS3 Compliant and REACH Unaffected, meeting environmental and regulatory requirements equivalent to the original RT0402FRE075K23L.
