• Composition: Thick Film
• Temperature Coefficient: ±100ppm/°C
• Operating Temperature: -55°C ~ 155°C minimum
• RoHS3 Compliance
• MSL 1 Rating

Power Rating Classification:

• Direct Equivalents (1/8W): RC0805FR-07820KL, ERJ-6ENF8203V, KTR10EZPF8203 - Identical power dissipation capability
• Upgrade Options (1/2W): CRCW0805820KFKEAHP, ERJ-UP6F8203V - Higher power handling for demanding applications

Automotive Qualification:

• Standard Grade: RC2012F824CS (Samsung), RC0805FR-07820KL (YAGEO)
• AEC-Q200 Qualified: AC0805FR-07820KL, CRCW0805820KFKEA, CRCW0805820KFKEAHP, ERJ-6ENF8203V, ERJ-UP6F8203V, KTR10EZPF8203

Parameter Comparison

Engineering Selection Recommendations

Direct Substitution (Equivalent Performance): RC0805FR-07820KL (YAGEO) provides direct electrical and mechanical equivalence to RC2012F824CS with identical 0.125W power rating and -55°C to 155°C operating range. This part is suitable for non-automotive applications requiring standard-grade thick film resistors.

Automotive-Grade Upgrade: AC0805FR-07820KL, CRCW0805820KFKEA, ERJ-6ENF8203V, and KTR10EZPF8203 are AEC-Q200 qualified alternatives maintaining 0.125W power rating. These parts are specified for automotive and high-reliability applications where automotive qualification is mandatory. Selection among these four depends on secondary features: KTR10EZPF8203 includes high-voltage capability; CRCW0805820KFKEA offers the lowest profile (0.50mm height); ERJ-6ENF8203V provides highest inventory availability (70,237 units).

Enhanced Power Handling: CRCW0805820KFKEAHP and ERJ-UP6F8203V provide 0.5W (1/2W) power rating with AEC-Q200 qualification. CRCW0805820KFKEAHP is selected for pulse-withstanding applications; ERJ-UP6F8203V adds anti-sulfur protection for corrosive environments. These upgrades are applicable only when circuit design permits higher power dissipation without thermal management changes.

Compliance Verification: All substitute parts maintain ROHS3 compliance, MSL 1 rating, and identical temperature coefficient (±100ppm/°C). No additional qualification testing is required for electrical parameter equivalence.

Frequently Asked Questions (FAQ)

Q: Can RC0805FR-07820KL replace RC2012F824CS in any application? A: RC0805FR-07820KL is electrically and mechanically equivalent for non-automotive applications. Both parts share identical resistance (820 kΩ), tolerance (±1%), power rating (0.125W), package (0805), and operating temperature range (-55°C to 155°C). The primary difference is that RC0805FR-07820KL lacks automotive AEC-Q200 qualification. Substitution is valid only when automotive qualification is not a design requirement.

Q: What is the difference between 1/8W and 1/2W rated parts? A: Power rating indicates maximum continuous power dissipation capability. 1/8W (0.125W) parts dissipate up to 0.125W; 1/2W (0.5W) parts dissipate up to 0.5W. Selection depends on circuit current and voltage: P = I²R. For 820 kΩ resistor at 10V, power dissipation is approximately 0.122W, requiring minimum 1/8W rating. Higher power ratings provide design margin and thermal headroom but do not improve electrical performance at lower power levels.

Q: Are all AEC-Q200 qualified parts interchangeable? A: AEC-Q200 qualification confirms automotive-grade reliability testing and environmental stress screening. All AEC-Q200 parts listed (AC0805FR-07820KL, CRCW0805820KFKEA, CRCW0805820KFKEAHP, ERJ-6ENF8203V, ERJ-UP6F8203V, KTR10EZPF8203) meet identical automotive standards. Interchangeability is confirmed for electrical parameters; however, secondary features differ: high-voltage capability (KTR10EZPF8203), anti-sulfur protection (ERJ-UP6F8203V), pulse withstanding (CRCW0805820KFKEAHP, ERJ-UP6F8203V). Verify secondary features against circuit requirements before substitution.

Q: Does package height affect PCB assembly? A: Package height ranges from 0.50mm (CRCW series) to 0.70mm (ERJ-6EN, ERJ-UP6 series). Height differences are within 0.20mm tolerance and do not affect standard PCB assembly processes or solder reflow profiles. Height becomes relevant only in space-constrained designs with height restrictions below 0.66mm, where CRCW0805820KFKEA (0.50mm) or AC0805FR-07820KL (0.60mm) are preferred.

Q: What is MSL 1 rating and why does it matter? A: MSL (Moisture Sensitivity Level) 1 indicates unlimited shelf life without moisture baking requirements. All listed parts carry MSL 1 rating, eliminating moisture-related handling restrictions. Parts can be stored at standard conditions (23°C, 50% RH) indefinitely without pre-reflow baking. This simplifies supply chain logistics and reduces manufacturing process complexity.

Q: Can I use CRCW0805820KFKEAHP (1/2W) instead of RC2012F824CS (1/8W)? A: Yes, CRCW0805820KFKEAHP is a valid upgrade substitute. Higher power rating (0.5W vs. 0.125W) provides additional thermal margin and reliability headroom. Electrical parameters remain identical: 820 kΩ ±1%, ±100ppm/°C, -55°C to 155°C. Upgrade is recommended for high-reliability applications, pulse-withstanding circuits, or designs operating near maximum power dissipation limits. No circuit redesign is required.

Q: Which substitute offers best inventory availability? A: ERJ-6ENF8203V (Panasonic) provides highest inventory: 70,237 units in stock. CRCW0805820KFKEA (Vishay Dale) offers 27,289 units. RC0805FR-07820KL (YAGEO) provides 42,951 units. Inventory levels support high-volume procurement and reduce lead time risk. Verify current stock status with supplier before final part selection.
