Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RCS2012F5903CS is determined by strict alignment of the following parameters:

Critical Matching Parameters:

• Resistance value: 590 kOhms
• Tolerance: ±1%
• Power rating: 0.125W (1/8W)
• Package: 0805 (2012 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity level: 1 (Unlimited)

All identified substitute parts meet these electrical and mechanical criteria. Variations in physical height, packaging format (Tape & Reel versus Cut Tape), and optional automotive certifications do not affect functional substitutability in standard applications.

Frequently Asked Questions (FAQ)

Q: Can CRCW0805590KFKEA replace RCS2012F5903CS in non-automotive applications?

A: Yes. The CRCW0805590KFKEA meets all electrical and mechanical specifications of the RCS2012F5903CS. The AEC-Q200 automotive qualification is an additional feature that does not restrict use in standard applications.

Q: What is the significance of the height difference between substitute parts?

A: Physical height variations (0.020" to 0.028") are within acceptable tolerances for 0805 package components. These differences do not affect electrical performance or standard PCB assembly processes. Verify clearance in applications with height-constrained layouts.

Q: Are the packaging format differences (Tape & Reel versus Cut Tape) significant for substitution?

A: Packaging format affects supply chain logistics and assembly processes but does not impact electrical or mechanical compatibility. RC0805FR-07590KL is available in Cut Tape and Digi-Reel formats, while other parts are supplied in Tape & Reel format. Select based on assembly equipment requirements.

Q: Do all substitute parts have the same moisture sensitivity level?

A: Yes. All listed parts have Moisture Sensitivity Level 1 (Unlimited), indicating no moisture-related handling restrictions during storage or assembly.

Q: Which substitute part has the highest inventory availability?

A: RC0805FR-07590KL (YAGEO) has 835,695 pieces in stock, significantly higher than other alternatives. ERJ-6ENF5903V (Panasonic) has 59,031 pieces, CRCW0805590KFKEA (Vishay Dale) has 18,835 pieces, and RCS2012F5903CS (Samsung) has 937 pieces.
