Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC2012F5903CS is determined by strict equivalence across the following parameters: resistance value (590 kOhms), tolerance (±1%), power rating (0.125W), package type (0805 / 2012 Metric), composition (thick film), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C ~ 155°C). All identified substitute parts match these core electrical and mechanical specifications. Substitutes are categorized as Direct or Similar based on additional features: Direct substitutes share identical moisture-resistant or automotive AEC-Q200 certifications; Similar substitutes meet all electrical and mechanical requirements with alternative feature sets. Product status and compliance certifications (RoHS3, REACH Unaffected, EAR99) are consistent across all listed parts.

Parameter Comparison

Engineering Selection Recommendations

Direct Substitutes (Preferred for Equivalent Functionality):

ERJ-6ENF5903V (Panasonic) and RC0805FR-07590KL (YAGEO) are direct substitutes with active product status and full RoHS3 compliance. ERJ-6ENF5903V includes automotive AEC-Q200 qualification, suitable for applications requiring automotive-grade reliability. RC0805FR-07590KL maintains moisture-resistant construction matching the original part specification and offers the highest inventory availability (835,695 units). Both parts are electrically and mechanically equivalent with identical operating temperature range and tolerance specifications.

Alternative Substitutes (Application-Dependent Selection):

RMCF0805FT590K (Stackpole) and CRCW0805590KFKEA (Vishay Dale) are active products with automotive AEC-Q200 certification. CRCW0805590KFKEA features the lowest seated height (0.50mm), beneficial for space-constrained PCB layouts. RMCF0805FT590K maintains standard height (0.65mm) matching the original part.

Discontinued Component:

MCR10ERTF5903 (Rohm Semiconductor) is discontinued at DiGi Electronics and should not be selected for new designs or long-term supply requirements, despite meeting all electrical and mechanical specifications.

Frequently Asked Questions (FAQ)

Q: Can ERJ-6ENF5903V replace RC2012F5903CS in non-automotive applications?

A: Yes. ERJ-6ENF5903V meets all electrical specifications (590 kOhms ±1%, 0.125W, ±100ppm/°C, -55°C ~ 155°C) and mechanical requirements (0805 package). Automotive AEC-Q200 qualification provides additional reliability margin and does not restrict use in standard applications.

Q: What is the difference between moisture-resistant and automotive AEC-Q200 features?

A: Moisture-resistant construction (RC2012F5903CS, RC0805FR-07590KL) addresses humidity exposure during storage and operation. Automotive AEC-Q200 qualification (ERJ-6ENF5903V, RMCF0805FT590K, CRCW0805590KFKEA) certifies reliability under automotive environmental and thermal cycling conditions. These are independent feature sets; a part may have one, both, or neither.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed parts, including the main part RC2012F5903CS and all substitutes, are RoHS3 compliant and REACH Unaffected with EAR99 export classification.

Q: Does seated height variation affect PCB assembly compatibility?

A: Seated height ranges from 0.50mm (CRCW0805590KFKEA) to 0.70mm (ERJ-6ENF5903V). For standard PCB designs with 0805 package footprints, this variation is within normal manufacturing tolerance and does not affect assembly compatibility. Height becomes relevant only in applications with strict vertical clearance constraints.

Q: Why is MCR10ERTF5903 listed if it is discontinued?

A: MCR10ERTF5903 is included for reference purposes to document historical equivalence and support legacy design documentation. For new designs and procurement, select from active products: ERJ-6ENF5903V, RC0805FR-07590KL, RMCF0805FT590K, or CRCW0805590KFKEA.

Q: Can I mix substitute parts within a single assembly?

A: Yes. All substitute parts are electrically and mechanically equivalent. Mixing parts from different manufacturers within a single PCB assembly is permissible from a functional standpoint. Verify procurement and quality documentation requirements with your supply chain and quality assurance processes.

Q: What is the MSL (Moisture Sensitivity Level) significance?

A: All parts carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. These components do not require special dry-pack storage or baking procedures prior to soldering, simplifying handling and inventory management.
