MCR006YRTJ821 Equivalent & Substitute Parts

Part Overview

The MCR006YRTJ821 is an 820 Ohm ±5% thick film chip resistor manufactured by Rohm Semiconductor in 0201 package format with 0.05W power rating. This part is discontinued at DiGi Electronics, necessitating identification of functionally equivalent alternatives from active manufacturers. Substitute parts must maintain identical resistance value, package dimensions, and power dissipation characteristics while meeting current RoHS3 compliance and MSL requirements.

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence across five critical parameters: resistance value (820 Ohms), tolerance grade (±5%), power rating (0.05W), package format (0201), and composition (thick film). Parts are grouped into two categories based on tolerance specification:

Tolerance-Matched Substitutes (±5%): CRCW0201820RJNED, ERJ-1GNJ821C, and RC0603J821CS maintain identical tolerance to the original part, ensuring direct functional replacement without circuit redesign consideration.

Upgraded Tolerance Substitutes (±1%): CRCW0201820RFKED, CRCW0201820RFNED, ERJ-1GNF8200C, RC0201FR-07820RL, and RC0603F821CS provide tighter tolerance specifications. These parts are electrically compatible but offer improved accuracy for precision applications.

All substitute candidates share identical package dimensions (0.024" L x 0.012" W), height (0.010" max), termination count (2), and RoHS3/MSL compliance with the original part.

Engineering Selection Recommendations

All listed substitute parts are ROHS3 compliant and carry MSL Level 1 (Unlimited) moisture sensitivity rating, matching the original MCR006YRTJ821 specification. All candidates are currently in active production status, ensuring long-term supply availability.

For direct functional replacement requiring no circuit modification, select CRCW0201820RJNED, ERJ-1GNJ821C, or RC0603J821CS, which maintain the original ±5% tolerance specification.

For applications benefiting from improved tolerance performance, CRCW0201820RFKED, CRCW0201820RFNED, ERJ-1GNF8200C, RC0201FR-07820RL, and RC0603F821CS provide ±1% tolerance with extended operating temperature ranges up to 155°C (Vishay Dale variants).

Packaging format selection depends on assembly requirements: Tape & Reel (TR) packaging suits high-volume automated assembly, while Cut Tape (CT) packaging accommodates lower-volume or manual assembly processes.

Frequently Asked Questions (FAQ)

Q: Can I use a ±1% tolerance part as a substitute for the original ±5% part?

A: Yes. The ±1% tolerance parts (CRCW0201820RFKED, CRCW0201820RFNED, ERJ-1GNF8200C, RC0201FR-07820RL, RC0603F821CS) are electrically compatible and provide superior accuracy. They are direct functional upgrades requiring no circuit redesign.

Q: What is the difference between Tape & Reel and Cut Tape packaging?

A: Tape & Reel (TR) packaging is optimized for automated pick-and-place assembly in high-volume production. Cut Tape (CT) packaging is supplied in individual tape segments and suits lower-volume or manual assembly operations. Both formats contain identical components in the same 0201 package.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts carry ROHS3 Compliant certification and MSL Level 1 (Unlimited) rating, matching the original part's environmental compliance status.

Q: Does operating temperature range affect substitution eligibility?

A: Operating temperature range does not restrict substitution. The original part operates -55°C to 125°C. Substitute parts with extended ranges (-55°C to 155°C) are fully compatible and provide additional thermal margin for demanding applications.

Q: What is the significance of temperature coefficient differences?

A: Temperature coefficient (ppm/°C) indicates resistance value drift across temperature extremes. The original part specifies ±250ppm/°C. Substitute parts range from ±100ppm/°C to ±250ppm/°C. Lower values indicate better temperature stability but do not affect basic substitution compatibility.

Q: Can I mix different substitute part manufacturers in the same circuit board?

A: Yes. All substitute parts meet identical electrical and mechanical specifications for the 820 Ohm 0201 thick film resistor category. Mixed-manufacturer designs are functionally equivalent and assembly-compatible.
