Engineering Selection Recommendations

For Direct Replacement (Identical Specifications): MCR006YRTJ821 from Rohm Semiconductor provides identical electrical and thermal characteristics to the original MCR006YZPJ821, with the primary difference being packaging format (Cut Tape / Digi-Reel versus bulk). This part maintains the same tolerance (±5%), temperature coefficient (±250ppm/°C), and operating range (-55°C ~ 125°C). Product status is discontinued at DiGi Electronics.

For Active Production (Recommended for New Designs): CRCW0201820RFNED and CRCW0201820RFKED from Vishay Dale are active products offering improved specifications. Both feature ±1% tolerance and extended operating temperature range (-55°C ~ 155°C). CRCW0201820RFNED provides ±200ppm/°C temperature coefficient, while CRCW0201820RFKED offers superior ±100ppm/°C performance. Both are ROHS3 compliant with MSL 1 rating.

CRCW0201820RJNED from Vishay Dale maintains ±5% tolerance matching the original specification while offering active product status, extended temperature range, and improved availability.

For Moisture-Resistant Applications: RC0603F821CS and RC0603J821CS from Samsung Electro-Mechanics provide moisture-resistant thick film construction. RC0603F821CS offers ±1% tolerance; RC0603J821CS maintains ±5% tolerance. Both feature identical operating temperature range (-55°C ~ 125°C) and temperature coefficient (±250ppm/°C) to the original part, with active product status.

All substitute parts maintain ROHS3 compliance and MSL 1 rating, ensuring compatibility with standard manufacturing and storage requirements.

Frequently Asked Questions (FAQ)

Q: Can MCR006YRTJ821 be used as a direct replacement for MCR006YZPJ821? A: Yes. MCR006YRTJ821 is electrically and mechanically identical to MCR006YZPJ821, with matching 820 Ohm resistance, ±5% tolerance, 0.05W power rating, and 0201 package. The primary difference is packaging format (Cut Tape / Digi-Reel). Both are discontinued at DiGi Electronics.

Q: What is the advantage of using CRCW0201820RFNED over the original MCR006YZPJ821? A: CRCW0201820RFNED offers three key advantages: (1) Active product status ensuring continued availability, (2) Tighter tolerance of ±1% versus ±5%, and (3) Extended operating temperature range of -55°C ~ 155°C versus -55°C ~ 125°C. All other parameters including package, power rating, and compliance certifications remain compatible.

Q: Are Samsung Electro-Mechanics RC0603F821CS and RC0603J821CS suitable replacements? A: Yes, both are suitable replacements. RC0603F821CS provides ±1% tolerance; RC0603J821CS maintains ±5% tolerance matching the original. Both feature moisture-resistant thick film construction, identical operating temperature range (-55°C ~ 125°C), and active product status. Package and power rating are fully compatible.

Q: What is the difference between CRCW0201820RFKED and CRCW0201820RFNED? A: Both are Vishay Dale 820 Ohm ±1% resistors in 0201 package with 0.05W rating and active status. The primary difference is temperature coefficient: CRCW0201820RFKED offers ±100ppm/°C (superior stability), while CRCW0201820RFNED provides ±200ppm/°C. Both support extended operating range (-55°C ~ 155°C).

Q: Can I use a ±1% tolerance part as a substitute for a ±5% tolerance requirement? A: Yes. Tighter tolerance (±1%) is always acceptable as a substitute for looser tolerance (±5%) specifications. The component will meet or exceed the original tolerance requirement. This applies to all upgrade parts listed.

Q: Are all substitute parts ROHS3 compliant? A: Yes. All listed substitute parts maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating, matching the original MCR006YZPJ821 specifications.

Q: What packaging options are available for these substitutes? A: Rohm MCR006YRTJ821 is available in Cut Tape / Digi-Reel format. Vishay Dale CRCW series parts are supplied in Tape & Reel packaging.
