Key Parameters

Substitute Part Grouping Explanation

Substitution of the RCS2012F4870CS is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 487 Ohms
• Tolerance: ±1%
• Power rating: 0.125W (1/8W)
• Package: 0805 (2012 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C
• Number of terminations: 2
• RoHS3 compliance
• MSL rating: 1 (Unlimited)

All identified substitute parts meet these mandatory parameters. Substitute parts are grouped by additional features and certifications:

Group 1 - Automotive Qualified (AEC-Q200): CRCW0805487RFKEA (Vishay Dale), ERJ-6ENF4870V (Panasonic), RMCF0805FT487R (Stackpole Electronics)

Group 2 - General Purpose: RC0805FR-07487RL (YAGEO)

Parameter Comparison

Engineering Selection Recommendations

For General-Purpose Applications: The RCS2012F4870CS (Samsung Electro-Mechanics) and RC0805FR-07487RL (YAGEO) are functionally equivalent for non-automotive applications. Both parts are Active status, RoHS3 compliant, and meet all electrical and mechanical specifications. Selection between these two is based on supply availability and sourcing preferences.

For Automotive Applications: When AEC-Q200 automotive qualification is required, substitute parts CRCW0805487RFKEA (Vishay Dale), ERJ-6ENF4870V (Panasonic), or RMCF0805FT487R (Stackpole Electronics) are appropriate selections. All three maintain identical electrical parameters and operating temperature ranges while providing automotive-grade reliability certification.

Height Considerations: All substitute parts exhibit seated heights within a 0.008" (0.20mm) range. The CRCW0805487RFKEA offers the lowest profile at 0.020" (0.50mm), while ERJ-6ENF4870V reaches 0.028" (0.70mm). For space-constrained designs, the Vishay Dale part provides maximum clearance; for standard applications, all parts are mechanically compatible.

Supply and Inventory: ERJ-6ENF4870V (Panasonic) offers the highest inventory availability at 165,299 pieces. CRCW0805487RFKEA (Vishay Dale) provides 15,062 pieces. RC0805FR-07487RL (YAGEO) stocks 34,905 pieces. RMCF0805FT487R (Stackpole) maintains 819 pieces. RCS2012F4870CS (Samsung) has 957 pieces in stock.

Frequently Asked Questions (FAQ)

Q: Can I substitute the RCS2012F4870CS with any of the listed equivalent parts without design modification?

A: Yes. All listed substitute parts are electrically and mechanically equivalent. They share identical resistance values (487 Ohms), tolerance (±1%), power rating (0.125W), package (0805), composition (thick film), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C to 155°C). Direct substitution is supported without circuit redesign.

Q: What is the difference between automotive-qualified and general-purpose versions?

A: Automotive-qualified parts (CRCW0805487RFKEA, ERJ-6ENF4870V, RMCF0805FT487R) carry AEC-Q200 certification, indicating compliance with automotive reliability and quality standards. General-purpose parts (RCS2012F4870CS, RC0805FR-07487RL) do not carry this certification. Selection depends on application requirements; automotive applications typically mandate AEC-Q200 qualification.

Q: Are there any height restrictions I should consider when substituting?

A: Seated heights vary slightly across substitute parts, ranging from 0.020" (0.50mm) to 0.028" (0.70mm). The original RCS2012F4870CS measures 0.026" (0.66mm). For applications with tight vertical clearance, verify the specific height requirement against the substitute part's maximum seated height. All parts remain within standard 0805 package specifications.

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

A: Yes. All parts listed, including the RCS2012F4870CS, carry MSL rating 1 (Unlimited), indicating no moisture sensitivity restrictions. Storage and handling requirements are identical across all equivalent parts.

Q: Which substitute part offers the best supply availability?

A: ERJ-6ENF4870V (Panasonic Electronic Components) provides the highest inventory level at 165,299 pieces. This part is also automotive-qualified (AEC-Q200) and maintains all electrical and mechanical equivalence to the RCS2012F4870CS.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts, including the RCS2012F4870CS, are RoHS3 compliant and REACH unaffected. Environmental and regulatory compliance is uniform across all equivalent options.

Q: Can I use these substitute parts in high-temperature applications?

A: Yes. All parts operate across the identical temperature range of -55°C to 155°C with a temperature coefficient of ±100ppm/°C. Thermal performance is equivalent across all substitute options.
