Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence across the following parameters:

Resistance value: 820 Ohms
Tolerance: ±1%
Power rating: 0.05W minimum
Package: 0201 (0603 Metric)
Composition: Thick Film
Temperature coefficient: ±200ppm/°C
Operating temperature range: -55°C minimum to 125°C minimum (upper limit may vary)
Physical dimensions: 0.024" L × 0.012" W maximum
RoHS compliance: ROHS3 Compliant
MSL rating: 1 (Unlimited)

All listed substitute parts meet these core electrical and mechanical requirements. Differences in product status, inventory levels, and optional certifications (such as AEC-Q200 automotive qualification) are noted but do not disqualify substitution eligibility.

Engineering Selection Recommendations

Primary Substitute (Preferred): RC0201FR-07820RL (YAGEO)

This part maintains full electrical equivalence with the main part and shares the same manufacturer. It offers the highest inventory availability (155,670 units) and active product status. The operating temperature range extends to -55°C to 125°C, which is suitable for most applications within the -55°C to 155°C envelope of the original part.

Secondary Substitute (Cross-Manufacturer): CRCW0201820RFNED (Vishay Dale)

This Vishay Dale part provides direct electrical equivalence and matches the full operating temperature range (-55°C to 155°C) of the main part. It maintains active product status with substantial inventory (27,994 units) and ROHS3 compliance.

Automotive-Grade Alternative: AF0201FR-07820RL (YAGEO)

For applications requiring AEC-Q200 automotive qualification, this YAGEO part provides equivalent performance with anti-sulfur protection. It is actively produced and maintains AEC-Q200 certification. Operating temperature range is -55°C to 125°C.

Not Recommended for New Designs: RK73H1HTTC8200F (KOA Speer Electronics)

Although this part meets all electrical and mechanical requirements and carries AEC-Q200 qualification, its "Not For New Designs" status indicates manufacturer discontinuation trajectory. Use only for legacy system maintenance or repair applications.

Frequently Asked Questions (FAQ)

Q: Can RC0201FR-07820RL replace AC0201FR-07820RL in all applications?

A: RC0201FR-07820RL is electrically equivalent and mechanically compatible. The operating temperature range difference (-55°C to 125°C versus -55°C to 155°C) is the only parameter variance. For applications operating above 125°C, use CRCW0201820RFNED or the original part.

Q: What is the difference between AC0201FR-07820RL and AF0201FR-07820RL?

A: Both are YAGEO 820 Ohm 0201 resistors with AEC-Q200 qualification. AF0201FR-07820RL adds anti-sulfur protection and operates to 125°C maximum, while AC0201FR-07820RL operates to 155°C. Select AF0201FR-07820RL for corrosive environments; select AC0201FR-07820RL for extended high-temperature applications.

Q: Is cross-manufacturer substitution acceptable?

A: Yes. CRCW0201820RFNED (Vishay Dale) meets all electrical specifications, mechanical dimensions, and compliance requirements. Cross-manufacturer substitution is valid when all core parameters match.

Q: Why is RK73H1HTTC8200F marked "Not For New Designs"?

A: This designation indicates the manufacturer is transitioning away from this product line. While currently in stock and functionally equivalent, it should not be selected for new designs. Use for repair or legacy applications only.

Q: Does operating temperature range affect substitution eligibility?

A: Operating temperature range is a critical parameter. Parts rated to -55°C to 125°C are suitable substitutes for applications within that range. For applications requiring -55°C to 155°C operation, select parts with matching upper temperature limit (AC0201FR-07820RL or CRCW0201820RFNED).

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed parts carry ROHS3 Compliant status and MSL rating 1 (Unlimited), meeting environmental and moisture sensitivity requirements.
