Key Parameters

Substitute Part Grouping Explanation

Substitute parts for RCS2012F4871CS are grouped based on strict electrical and mechanical parameter matching. The primary substitution criteria are:

Critical Parameters (Must Match):

• Resistance value: 4.87 kOhms
• Tolerance: ±1%
• Package / Case: 0805 (2012 Metric)
• Composition: Thick Film
• Temperature Coefficient: ±100ppm/°C
• Operating Temperature Range: -55°C ~ 155°C
• Moisture Sensitivity Level: 1 (Unlimited)
• RoHS Status: ROHS3 Compliant

Power Rating Consideration: Substitutes are divided into two categories based on power rating:

• 1/8W (0.125W) Category: Direct equivalents with identical power rating
• 1/2W (0.5W) Category: Higher power rating substitutes for applications requiring enhanced pulse withstanding or thermal margin

All substitute parts maintain identical resistance, tolerance, package dimensions, temperature coefficient, and compliance certifications as the main part.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalents (1/8W, 0.125W Power Rating):

CRCW08054K87FKEA, ERJ-6ENF4871V, RC0805FR-074K87L, and RMCF0805FT4K87 are direct electrical and mechanical equivalents to RCS2012F4871CS. These parts maintain identical resistance, tolerance, power rating, temperature coefficient, and operating temperature range. All are ROHS3 compliant with MSL 1 rating. Selection among these direct equivalents is based on:

• Manufacturer availability and supply chain preference
• Automotive AEC-Q200 certification requirement (CRCW08054K87FKEA, ERJ-6ENF4871V, RMCF0805FT4K87 carry this rating)
• Specific feature requirements (anti-sulfur vs. moisture resistant vs. automotive qualification)
• Height-seated dimension constraints in PCB layout (ranging from 0.50mm to 0.70mm)

Higher Power Rating Substitutes (1/2W, 0.5W Power Rating):

CRCW08054K87FKEAHP and RCS08054K87FKEA provide 0.5W power rating while maintaining all other electrical parameters. These substitutes are applicable when:

• Circuit design requires enhanced thermal margin or pulse withstanding capability
• PCB layout accommodates the identical 0805 package footprint
• Automotive AEC-Q200 qualification is required
• Pulse withstanding performance is specified

All substitute parts maintain ROHS3 compliance, unlimited MSL rating, and -55°C to 155°C operating temperature range consistent with the main part.

Frequently Asked Questions (FAQ)

Q1: Can CRCW08054K87FKEAHP (0.5W) be used as a direct replacement for RCS2012F4871CS (0.125W)?

A: Yes, from an electrical and mechanical standpoint. The 0.5W part maintains identical resistance (4.87 kOhms), tolerance (±1%), package (0805), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C ~ 155°C). The higher power rating provides additional thermal margin and pulse withstanding capability. However, circuit design must accommodate the identical 0805 footprint. Verify that the application does not have power dissipation constraints that would be negatively affected by the higher rated component.

Q2: What is the difference between automotive AEC-Q200 rated parts and non-automotive rated parts in this list?

A: Automotive AEC-Q200 certification (CRCW08054K87FKEA, ERJ-6ENF4871V, RMCF0805FT4K87, CRCW08054K87FKEAHP, RCS08054K87FKEA) indicates compliance with automotive industry reliability and quality standards. The main part RCS2012F4871CS and RC0805FR-074K87L do not carry this designation. Selection depends on application requirements: automotive applications typically require AEC-Q200 certification, while industrial or consumer applications may not.

Q3: Are all substitute parts available in Tape & Reel (TR) packaging?

A: Yes, all substitute parts listed are supplied in Tape & Reel (TR) packaging, consistent with the main part RCS2012F4871CS. This packaging format is standard for high-volume SMD component procurement and automated assembly processes.

Q4: What is the significance of the Height-Seated (Max) dimension variation among substitute parts?

A: Height-seated dimensions range from 0.50mm to 0.70mm across the substitute parts. While all components use the 0805 (2012 Metric) package, height variation may impact PCB design considerations in applications with tight vertical clearance constraints or specific solder reflow profile requirements. Verify PCB layout clearance specifications before selecting a substitute with different height characteristics.

Q5: Can I substitute RCS2012F4871CS with RC0805FR-074K87L from YAGEO?

A: Yes, RC0805FR-074K87L is a direct equivalent. Both parts share identical electrical specifications: 4.87 kOhms ±1%, 0.125W power rating, ±100ppm/°C temperature coefficient, -55°C ~ 155°C operating range, 0805 package, ROHS3 compliance, and MSL 1 rating. The primary difference is manufacturer (YAGEO vs. Samsung Electro-Mechanics) and feature designation (moisture resistant vs. anti-sulfur, moisture resistant). Selection is based on supply chain availability and procurement preference.

Q6: Which substitute part has the lowest seated height?

A: CRCW08054K87FKEA and RCS08054K87FKEA (both Vishay Dale) have the lowest maximum seated height at 0.50mm, compared to 0.66mm for the main part RCS2012F4871CS. This may be advantageous for applications with vertical space constraints, though all parts maintain identical 0805 package footprint dimensions.

Q7: Are all parts REACH compliant?

A: Yes, all parts listed (main part and substitutes) are REACH Unaffected, indicating compliance with REACH (Registration, Evaluation, Authorization and Restriction of Chemicals) regulations.

Q8: What inventory availability should I consider when selecting a substitute?

A: Inventory levels vary significantly: ERJ-6ENF4871V (Panasonic) shows 150,400 pcs, CRCW08054K87FKEA (Vishay Dale) shows 22,398 pcs, and CRCW08054K87FKEAHP shows 4,162 pcs. Higher inventory availability may support shorter lead times and supply chain continuity. However, component selection should prioritize electrical and mechanical compatibility over inventory levels alone.
