Engineering Selection Recommendations

CPF0402B187RE1 (TE Connectivity Passive Product) Offers improved tolerance specification (±0.1% versus ±1%) and lower temperature coefficient (±25ppm/°C versus ±50ppm/°C). Operating temperature range matches the original part (-55°C ~ 155°C). RoHS3 compliant with MSL 1 rating. Height-seated dimension is 0.014" (0.35mm), slightly lower than the original 0.015" (0.37mm), suitable for space-constrained applications.

RR0510P-1870-D (Susumu) Provides tolerance of ±0.5% and temperature coefficient of ±25ppm/°C. Operating temperature range is -55°C ~ 125°C, which is narrower than the original specification. Height-seated dimension is 0.016" (0.40mm), slightly higher than the original. RoHS3 compliant with MSL 1 rating. Suitable for applications where the reduced upper temperature limit is acceptable.

RT0402BRD07187RL (YAGEO) Delivers improved tolerance specification (±0.1% versus ±1%) and lower temperature coefficient (±25ppm/°C versus ±50ppm/°C). Operating temperature range matches the original part (-55°C ~ 155°C). RoHS3 compliant with MSL 1 rating. Height-seated dimension is 0.014" (0.35mm), matching CPF0402B187RE1 and suitable for compact PCB layouts.

Frequently Asked Questions (FAQ)

Q: Can CPF0402B187RE1 be used as a direct replacement for MCS04020C1870FE000? A: Yes. Both parts share identical resistance (187 Ohms), package (0402), power rating (0.063W), and operating temperature range (-55°C ~ 155°C). CPF0402B187RE1 provides superior tolerance (±0.1%) and temperature coefficient (±25ppm/°C), making it a direct upgrade.

Q: What is the key difference between RR0510P-1870-D and the other substitutes? A: RR0510P-1870-D has a narrower operating temperature range (-55°C ~ 125°C) compared to the original part and other substitutes (-55°C ~ 155°C). This part is suitable only for applications where the maximum operating temperature does not exceed 125°C.

Q: Are all substitute parts available in the same packaging format? A: Yes. All substitute parts are supplied in Tape & Reel (TR) packaging and use the 0402 (1005 Metric) package / case format, ensuring compatibility with standard SMD assembly processes.

Q: What does tolerance specification mean for circuit performance? A: Tolerance defines the acceptable deviation from the nominal resistance value. MCS04020C1870FE000 has ±1% tolerance, meaning the actual resistance can range from 185.13 Ohms to 188.87 Ohms. Substitute parts with ±0.1% tolerance (CPF0402B187RE1 and RT0402BRD07187RL) provide tighter resistance accuracy, beneficial for precision analog circuits.

Q: Does temperature coefficient affect part selection? A: Temperature coefficient indicates how resistance changes with temperature. MCS04020C1870FE000 has ±50ppm/°C, while substitutes have ±25ppm/°C, meaning substitute parts exhibit half the resistance drift over temperature. This is advantageous for temperature-sensitive applications.

Q: Are all parts RoHS3 compliant? A: Yes. MCS04020C1870FE000 and all three substitute parts are RoHS3 compliant with MSL 1 (Unlimited) moisture sensitivity level, meeting environmental and reliability standards.
