TRR03EZPJ821 Equivalent & Substitute Parts

Part Overview

The TRR03EZPJ821 is a 820 Ohms ±5% 0.1W thick film chip resistor in 0603 (1608 Metric) package manufactured by Rohm Semiconductor. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing production and maintenance applications. The part features anti-sulfur construction, ROHS3 compliance, and operates across -55°C to 155°C temperature range.

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following parameters: resistance value (820 Ohms), package type (0603), power rating (0.1W), composition (thick film), anti-sulfur feature, operating temperature range (-55°C ~ 155°C), and RoHS3 compliance. All substitute parts listed maintain these core electrical and mechanical specifications.

Substitute parts are grouped into two categories based on tolerance specification:

Direct Tolerance Match (±5%): ERJ-S03J821V maintains the original ±5% tolerance specification, providing direct functional equivalence with identical temperature coefficient (±200ppm/°C).

Upgraded Tolerance (±1%): RMCS0603FT820R and AF0603FR-07820RL and ERJ-S03F8200V offer tighter ±1% tolerance with improved temperature coefficient (±100ppm/°C), suitable for applications requiring higher precision.

Engineering Selection Recommendations

For Direct Replacement: ERJ-S03J821V is the primary substitute, maintaining identical tolerance (±5%) and temperature coefficient (±200ppm/°C) specifications. This part is manufactured by Panasonic Electronic Components with active product status and includes AEC-Q200 automotive qualification, providing enhanced reliability for automotive and industrial applications.

For Precision Applications: RMCS0603FT820R, AF0603FR-07820RL, and ERJ-S03F8200V offer improved tolerance (±1%) and lower temperature coefficient (±100ppm/°C). AF0603FR-07820RL and ERJ-S03F8200V include AEC-Q200 certification. All four substitute parts are actively manufactured and ROHS3 compliant, ensuring long-term availability and regulatory compliance.

Availability Consideration: All substitute parts are in active production status with confirmed inventory availability, eliminating supply chain risk associated with the obsolete TRR03EZPJ821.

Frequently Asked Questions (FAQ)

Q: Can ERJ-S03J821V be used as a direct replacement for TRR03EZPJ821? A: Yes. ERJ-S03J821V maintains identical resistance (820 Ohms), tolerance (±5%), power rating (0.1W), package (0603), temperature range (-55°C ~ 155°C), and anti-sulfur feature. Both parts are ROHS3 compliant with MSL rating 1.

Q: What is the difference between the ±5% and ±1% tolerance substitutes? A: The ±5% tolerance substitute (ERJ-S03J821V) provides direct functional equivalence. The ±1% tolerance substitutes (RMCS0603FT820R, AF0603FR-07820RL, ERJ-S03F8200V) offer tighter tolerance and lower temperature coefficient (±100ppm/°C versus ±200ppm/°C), suitable for precision circuits requiring higher accuracy.

Q: Are all substitute parts available in the same packaging format? A: Yes. All substitute parts are supplied in 0603 (1608 Metric) package with identical physical dimensions (0.063" L x 0.031" W, 1.60mm x 0.80mm) and maximum seated height (0.022", 0.55mm), ensuring direct PCB compatibility.

Q: Do the substitute parts meet automotive standards? A: ERJ-S03J821V, AF0603FR-07820RL, and ERJ-S03F8200V include AEC-Q200 automotive qualification. RMCS0603FT820R does not carry AEC-Q200 certification but meets all electrical and environmental specifications.

Q: What is the product status of the substitute parts? A: All four substitute parts are in active production status, ensuring long-term availability and supply chain stability compared to the obsolete TRR03EZPJ821.
