Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by three core parameters: resistance value, package type, and power rating. All substitute parts maintain 187 Ohm resistance, 0402 package format, and 0.063W power rating, ensuring direct mechanical and electrical compatibility.

Tolerance and temperature coefficient variations define substitution categories:

Tolerance-Upgraded Substitutes (±0.1%): RT0402BRD07187RL (YAGEO) and CPF0402B187RE1 (TE Connectivity) provide improved tolerance specifications with ±25ppm/°C temperature coefficient, suitable for precision circuit applications.

Automotive-Grade Substitute (±0.1%, AEC-Q200): ERA-2AEB1870X (Panasonic) meets automotive reliability standards with AEC-Q200 qualification while maintaining ±0.1% tolerance and ±25ppm/°C temperature coefficient.

Tolerance-Relaxed Substitute (±0.5%): RR0510P-1870-D (Susumu) offers ±0.5% tolerance with ±25ppm/°C temperature coefficient and operates to 125°C maximum, suitable for non-critical applications requiring alternative sourcing.

Parameter Comparison

Engineering Selection Recommendations

For Precision Applications: RT0402BRD07187RL and CPF0402B187RE1 are direct upgrades from RT0402FRE07187RL, offering ±0.1% tolerance and improved temperature coefficient (±25ppm/°C vs. ±50ppm/°C). Both maintain full temperature range (-55°C to 155°C) and ROHS3 compliance.

For Automotive Applications: ERA-2AEB1870X provides AEC-Q200 qualification with ±0.1% tolerance and ±25ppm/°C temperature coefficient. This part is specified for automotive-grade reliability requirements while maintaining the full operating temperature range.

For Alternative Sourcing: RR0510P-1870-D (Susumu) maintains core electrical specifications with ±0.5% tolerance and ±25ppm/°C temperature coefficient. Operating temperature maximum is 125°C, which is acceptable for applications not requiring the full -55°C to 155°C range. This option provides manufacturer diversity.

All substitute parts are ROHS3 compliant with MSL 1 rating and maintain identical 0402 package dimensions and 0.063W power rating.

Frequently Asked Questions (FAQ)

Q: Can RT0402BRD07187RL directly replace RT0402FRE07187RL? A: Yes. Both parts share identical resistance (187 Ohms), package (0402), power rating (0.063W), and operating temperature range (-55°C to 155°C). RT0402BRD07187RL provides improved tolerance (±0.1% vs. ±1%) and lower temperature coefficient (±25ppm/°C vs. ±50ppm/°C).

Q: What is the difference between CPF0402B187RE1 and RT0402BRD07187RL? A: Both parts have identical electrical specifications: 187 Ohms, ±0.1% tolerance, ±25ppm/°C temperature coefficient, and 0402 package. The primary difference is manufacturer (TE Connectivity vs. YAGEO). Selection depends on supply chain requirements and preferred vendor qualification.

Q: Is ERA-2AEB1870X suitable for non-automotive applications? A: Yes. ERA-2AEB1870X meets AEC-Q200 automotive standards but is fully compatible with general industrial and commercial applications. The automotive qualification represents an additional quality assurance level.

Q: Can RR0510P-1870-D be used in applications requiring -55°C to 155°C operation? A: No. RR0510P-1870-D operates to 125°C maximum. For applications requiring full -55°C to 155°C range, use RT0402FRE07187RL, RT0402BRD07187RL, CPF0402B187RE1, or ERA-2AEB1870X.

Q: Are all substitute parts ROHS3 compliant? A: Yes. All listed parts (RT0402FRE07187RL, RT0402BRD07187RL, CPF0402B187RE1, ERA-2AEB1870X, and RR0510P-1870-D) are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Q: What determines if a part can substitute for RT0402FRE07187RL? A: Core substitution criteria are: 187 Ohm resistance value, 0402 package format, and 0.063W power rating. Tolerance, temperature coefficient, and operating temperature range may vary based on application requirements. All substitutes must maintain ROHS3 compliance and MSL 1 rating.
