Substitute Part Grouping Explanation

Substitution of the RC2012F4423CS is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

• Resistance value: 442 kOhms (exact match)
• Tolerance: ±1% (exact match)
• Power rating: 0.125W / 1/8W (exact match)
• Temperature coefficient: ±100ppm/°C (exact match)
• Operating temperature range: -55°C ~ 155°C (exact match)

Mechanical Equivalence Requirements:

• Package / Case: 0805 (2012 Metric) (exact match)
• Number of terminations: 2 (exact match)
• Composition: Thick Film (exact match)

Compliance & Environmental Requirements:

• RoHS Status: ROHS3 Compliant (minimum requirement)
• Moisture Sensitivity Level: 1 (Unlimited) (minimum requirement)
• REACH Status: REACH Unaffected (minimum requirement)

All substitute parts listed maintain identical electrical performance, mechanical compatibility, and environmental compliance with the main part. Dimensional variations in height (seated maximum) do not affect functional substitution within standard PCB assembly processes.

Frequently Asked Questions (FAQ)

Q: Can RC0805FR-07442KL (YAGEO) be used as a direct replacement for RC2012F4423CS (Samsung)?

A: Yes. RC0805FR-07442KL is a direct substitute. Both parts share identical electrical specifications (442 kOhms ±1%, 0.125W), operate across -55°C to 155°C, use thick film composition, and are packaged in 0805 (2012 Metric) format. Both maintain ROHS3 compliance and MSL 1 rating. The 0.006" (0.06mm) difference in seated height does not affect PCB assembly compatibility.

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

A: The RC2012F4423CS features moisture-resistant thick film construction. The CRCW0805442KFKEA, ERJ-6ENF4423V, and RMCF0805FT442K variants additionally carry AEC-Q200 automotive qualification, indicating enhanced reliability testing and qualification for automotive applications. Both types maintain MSL 1 (Unlimited) moisture sensitivity rating and are suitable for general industrial use.

Q: Are all substitute parts available in Tape & Reel (TR) packaging?

A: Yes. All listed substitute parts are supplied in Tape & Reel (TR) packaging format, matching the original RC2012F4423CS packaging specification for automated assembly compatibility.

Q: Can these 0805 resistors be used in high-temperature applications?

A: All parts operate across the -55°C to 155°C temperature range with ±100ppm/°C temperature coefficient. This specification defines the operating limits. Applications requiring operation beyond 155°C require alternative component selection.

Q: What is the significance of the ±1% tolerance specification?

A: The ±1% tolerance indicates that the actual resistance value will fall within the range of 437.58 kOhms to 446.42 kOhms. This tight tolerance is maintained across all substitute parts and is suitable for precision analog circuits, filtering networks, and measurement applications requiring high accuracy.

Q: Are there any dimensional constraints for PCB layout when substituting these parts?

A: All parts conform to 0805 (2012 Metric) package dimensions: 0.079" L x 0.049" W (2.00mm x 1.25mm). Seated height variations (0.50mm to 0.70mm maximum) are within standard PCB assembly tolerances and do not require layout modifications. Standard 0805 footprints accommodate all listed substitutes.
