RT0402FRE07255RL Equivalent & Substitute Parts

Part Overview

The RT0402FRE07255RL is a 255 Ohm ±1% thin film chip resistor in 0402 (1005 Metric) package manufactured by YAGEO. This surface mount resistor is rated for 0.063W (1/16W) power dissipation and operates across -55°C to 155°C. The part is Active status and ROHS3 compliant with MSL 1 rating.

Substitute parts are identified when equivalent resistance values, package dimensions, power ratings, and operating temperature ranges align with the original specification. Higher tolerance grades (±0.1%) and improved temperature coefficients represent performance upgrades while maintaining full mechanical and electrical compatibility.

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following criteria:

Resistance Value: Must be 255 Ohms (exact match required)
Package Dimensions: Must be 0402 (1005 Metric) with compatible height specifications (0.014" to 0.016" seated height)
Power Rating: Must be 0.063W (1/16W) minimum
Operating Temperature Range: Must cover -55°C to 155°C or equivalent
Composition: Thin film construction required
Compliance: ROHS3 and MSL 1 required

Substitute parts may feature improved tolerance grades (±0.1% vs ±1%) and lower temperature coefficients (±10ppm/°C to ±25ppm/°C vs ±50ppm/°C). These represent performance enhancements without compromising mechanical or electrical compatibility. One substitute (RR0510P-2550-D) operates to 125°C maximum, which is within acceptable range for most applications but represents a reduced upper temperature limit.

RR0510P-2550-D (Susumu): ±0.5% tolerance with ±25ppm/°C coefficient. Maximum operating temperature limited to 125°C (30°C reduction from original). Height increased to 0.40mm. Suitable only for applications not requiring full -55°C to 155°C range.

Frequently Asked Questions (FAQ)

Q: Can RT0402BRD07255RL replace RT0402FRE07255RL directly on the PCB?

A: Yes. Both parts share identical 0402 package dimensions (1.00mm × 0.50mm) and seated height (0.35mm). The improved ±0.1% tolerance and ±25ppm/°C temperature coefficient represent performance enhancements with no mechanical incompatibility.

Q: What is the difference between ±1% and ±0.1% tolerance?

A: Tolerance defines the maximum deviation from the nominal 255 Ohm value. ±1% allows ±2.55 Ohms deviation (252.45–257.55 Ohms). ±0.1% allows ±0.255 Ohms deviation (254.745–255.255 Ohms). Higher precision tolerance grades are suitable for precision analog circuits and measurement applications.

Q: Why does ERA-2AEB2550X have a different height specification?

A: ERA-2AEB2550X has a maximum seated height of 0.40mm versus 0.35mm for other parts. This 0.05mm difference remains within standard PCB assembly tolerances and does not affect electrical performance or mechanical fit in typical 0402 footprints.

Q: Is RR0510P-2550-D suitable for all applications?

A: RR0510P-2550-D operates only to 125°C maximum, compared to 155°C for the original part. It is suitable only for applications where the upper operating temperature does not exceed 125°C. Verify application temperature requirements before selection.

Q: What does AEC-Q200 qualification mean for ERA-2AEB2550X?

A: AEC-Q200 is an automotive industry standard for passive component reliability. ERA-2AEB2550X meets this qualification, making it suitable for automotive and high-reliability applications requiring enhanced quality assurance and failure rate documentation.

Q: Can I mix different substitute parts in the same circuit?

A: Yes, provided all parts meet the circuit's tolerance and temperature coefficient requirements. Mixing parts with different tolerance grades (±1%, ±0.5%, ±0.1%) in the same circuit may introduce unintended circuit behavior if tolerance stack-up is critical to circuit function.
