Substitute Part Grouping Explanation
Substitution eligibility for the RC1608F9093CS is determined by strict equivalence across the following critical parameters:
- Resistance Value: 909 kOhms (exact match required)
- Tolerance: ±1% (exact match required)
- Power Rating: 0.1W / 1/10W (exact match required)
- Package: 0603 (1608 Metric) (exact match required)
- Composition: Thick Film (exact match required)
- Temperature Coefficient: ±100ppm/°C (exact match required)
- Operating Temperature Range: -55°C ~ 155°C (exact match required)
- Moisture Sensitivity Level: 1 (Unlimited) (exact match required)
- RoHS Compliance: ROHS3 Compliant (exact match required)
All substitute parts listed below meet these criteria. Additional features such as automotive AEC-Q200 qualification represent enhancements that do not preclude substitution but indicate suitability for extended application scopes.

Engineering Selection Recommendations
All five parts listed are functionally equivalent for standard applications. Selection among these options should be based on:
Direct Equivalents (No Additional Qualifications)
- CR0603-FX-9093ELF (Bourns Inc.) - Moisture-resistant thick film composition matching the original specification
- RC0603FR-07909KL (YAGEO) - Moisture-resistant thick film composition matching the original specification
Enhanced Specification Options (Automotive Applications)
- CRCW0603909KFKEA (Vishay Dale) - Includes AEC-Q200 automotive qualification
- ERJ-3EKF9093V (Panasonic Electronic Components) - Includes AEC-Q200 automotive qualification
All parts maintain ROHS3 compliance, unlimited moisture sensitivity rating (MSL 1), and identical electrical performance within the specified operating temperature range. Selection should prioritize availability, supply chain logistics, and application-specific requirements such as automotive certification when applicable.
Frequently Asked Questions (FAQ)
Q: Can CRCW0603909KFKEA or ERJ-3EKF9093V be used as direct replacements for RC1608F9093CS in non-automotive applications?
A: Yes. The automotive AEC-Q200 qualification is an additional feature that does not restrict use in general-purpose applications. All electrical and mechanical parameters remain equivalent.
Q: Are there dimensional differences between these parts?
A: Nominal package dimensions are 0603 (1608 Metric) for all parts. Minor variations exist in maximum seated height: RC1608F9093CS, RC0603FR-07909KL, and ERJ-3EKF9093V specify 0.022" (0.55mm), while CRCW0603909KFKEA specifies 0.020" (0.50mm). These differences are within standard PCB assembly tolerances and do not affect interchangeability.
Q: What is the difference between Tape & Reel and Cut Tape packaging?
A: Tape & Reel (TR) packaging is supplied on continuous carrier tape suitable for automated pick-and-place assembly. Cut Tape (CT) & Digi-Reel packaging provides smaller quantities on cut tape segments. Both formats contain identical components; packaging selection depends on production volume and assembly equipment compatibility.
Q: Are all parts REACH compliant?
A: Yes. All listed parts have REACH Unaffected status, indicating compliance with REACH regulations.
Q: Which part has the highest inventory availability?
A: RC0603FR-07909KL (YAGEO) shows 192,688 pieces in stock, providing the largest available inventory among the listed substitutes.
