Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for 845 kOhms ±1% 1/8W 0805 chip resistors is determined by strict equivalence across the following parameters:

Critical Matching Parameters:

• Resistance value: 845 kOhms (exact)
• Tolerance: ±1% (exact)
• Power rating: 0.125W / 1/8W (exact)
• Package: 0805 (2012 Metric) (exact)
• Composition: Thick Film (exact)
• Temperature coefficient: ±100ppm/°C (exact)
• Operating temperature range: -55°C ~ 155°C (exact)
• Moisture sensitivity level: 1 (Unlimited) (exact)
• RoHS compliance: ROHS3 Compliant (exact)

All identified substitute parts meet these criteria. Dimensional variations in seated height (0.020" to 0.028") remain within acceptable PCB assembly tolerances for 0805 packages. Substitute parts may include additional certifications such as AEC-Q200 automotive qualification, which represents enhanced reliability without compromising general-purpose application compatibility.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent (Preferred for Drop-In Replacement): RC0805FR-07845KL (YAGEO) is the primary direct equivalent, matching all electrical and mechanical specifications of the RC2012F8453CS without additional certifications. This part maintains identical functional performance for general-purpose applications.

Enhanced Reliability Alternatives (AEC-Q200 Qualified): CRCW0805845KFKEA (Vishay Dale), ERJ-6ENF8453V (Panasonic), and RMCF0805FT845K (Stackpole) are qualified to AEC-Q200 automotive standards. These parts are suitable for applications requiring automotive-grade reliability and are fully compatible with non-automotive designs. Selection among these three is based on availability and supply chain preference.

Selection Criteria:

• For general industrial and consumer applications: RC0805FR-07845KL or RC2012F8453CS
• For automotive or mission-critical applications: CRCW0805845KFKEA, ERJ-6ENF8453V, or RMCF0805FT845K
• All parts maintain ROHS3 compliance and REACH unaffected status
• All parts feature MSL 1 (Unlimited) moisture sensitivity rating

Frequently Asked Questions (FAQ)

Q: Can CRCW0805845KFKEA be used in place of RC2012F8453CS in a non-automotive application? A: Yes. AEC-Q200 qualification represents enhanced reliability testing and does not restrict use in non-automotive designs. The part is fully compatible.

Q: Are there dimensional concerns when substituting between these parts? A: Seated height varies from 0.020" to 0.028" across the part family. All variations remain within standard 0805 package tolerances and PCB assembly specifications. No design modifications are required.

Q: What is the difference between RC0805FR-07845KL and RC2012F8453CS? A: Both are 845 kOhms ±1% 1/8W 0805 thick film resistors with identical electrical specifications. RC0805FR-07845KL is manufactured by YAGEO; RC2012F8453CS is manufactured by Samsung Electro-Mechanics. Seated height differs by 0.002" (0.06mm), which is within acceptable tolerance.

Q: Do all substitute parts have the same moisture sensitivity rating? A: Yes. All parts listed carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions for storage or handling.

Q: Can I mix manufacturers in the same PCB assembly? A: Yes. All parts meet identical electrical and mechanical specifications. Mixed sourcing is permissible from an engineering compatibility standpoint.

Q: Which part has the lowest profile for space-constrained applications? A: CRCW0805845KFKEA (Vishay Dale) has the lowest seated height at 0.020" (0.50mm).

Q: Are all parts available in Tape & Reel packaging? A: Yes. All listed parts are supplied in Tape & Reel (TR) format suitable for automated assembly.
