Mandatory Matching Parameters:

Resistance value: 820 Ohms
Package: 0402 (1005 Metric)
Composition: Thick Film
Anti-Sulfur feature
Operating temperature range: -55°C to 155°C
RoHS3 compliance

Allowable Variations:

Tolerance: ±5% (primary specification) or tighter (±1%)
Power rating: 0.063W (1/16W) or higher (0.1W / 1/10W)
Temperature coefficient: ±100ppm/°C to ±200ppm/°C

Engineering Selection Recommendations

Direct Equivalent (Active Status): SFR01MZPJ821 is the primary direct equivalent. Manufactured by Rohm Semiconductor, it matches all electrical specifications of TRR01MZPJ821 while offering active product status and AEC-Q200 automotive qualification. This part is recommended for applications requiring identical performance characteristics with assured long-term availability.

Cross-Manufacturer Direct Equivalent (Active Status): AF0402JR-07820RL from YAGEO provides direct electrical equivalence with active status and AEC-Q200 certification. The temperature coefficient is improved to ±100ppm/°C. This part is suitable for applications where cross-manufacturer sourcing is acceptable.

Upgraded Tolerance (Active Status): TRR01MZPF8200 and ERJ-S02F8200X both offer ±1% tolerance, providing superior accuracy compared to the ±5% specification. TRR01MZPF8200 maintains the original 0.063W power rating but is obsolete. ERJ-S02F8200X is active with increased power rating (0.1W) and AEC-Q200 certification, making it suitable for applications requiring tighter tolerance and higher thermal margin.

Upgraded Power Rating (Active Status): ERJ-S02J821X maintains the ±5% tolerance while increasing power rating to 0.1W and includes AEC-Q200 certification. This part is recommended for applications where thermal headroom is required or where automotive-grade reliability is specified.

Frequently Asked Questions (FAQ)

Q: Can I use a substitute part with ±1% tolerance instead of ±5%? A: Yes. Tighter tolerance is a performance upgrade and is electrically compatible. The ±1% tolerance parts (TRR01MZPF8200, ERJ-S02F8200X) provide superior accuracy and are direct substitutes for the ±5% specification.

Q: What is the difference between 0.063W (1/16W) and 0.1W (1/10W) power ratings? A: The 0.1W rating provides higher thermal capacity. Parts with 0.1W rating (ERJ-S02F8200X, ERJ-S02J821X) can dissipate more power without exceeding temperature limits. They are compatible substitutes for applications using the original 0.063W specification.

Q: Why should I choose an AEC-Q200 certified part? A: AEC-Q200 certification indicates automotive-grade reliability testing and qualification. Parts with this certification (SFR01MZPJ821, AF0402JR-07820RL, ERJ-S02F8200X, ERJ-S02J821X) are recommended for automotive applications or where enhanced reliability is required.

Q: Is the 0402 package compatible across all substitute parts? A: Yes. All substitute parts use the 0402 (1005 Metric) package with identical footprint dimensions (0.039" L x 0.020" W). They are mechanically and electrically interchangeable at the PCB level.

Q: Can I use Panasonic ERJ-S02 series parts as direct replacements? A: Yes. ERJ-S02F8200X and ERJ-S02J821X are direct substitutes. Both maintain 820 Ohms resistance, anti-sulfur composition, and -55°C to 155°C operating range. The ERJ-S02J821X matches the original ±5% tolerance, while ERJ-S02F8200X offers ±1% tolerance with higher power rating.

Q: What is the temperature coefficient and why does it matter? A: Temperature coefficient (±100ppm/°C or ±200ppm/°C) indicates how resistance changes with temperature. Lower values indicate better stability. Parts with ±100ppm/°C (AF0402JR-07820RL, TRR01MZPF8200) provide superior temperature stability for precision applications.

Q: Are all substitute parts RoHS3 compliant? A: Yes. All listed substitute parts are ROHS3 compliant and REACH unaffected, meeting environmental and regulatory requirements.
