RC5025J221CS Equivalent & Substitute Parts Reference

Part Overview

The RC5025J221CS is a 220 Ohm ±5% thick film chip resistor manufactured by Samsung Electro-Mechanics, rated at 0.667W (2/3W) in a 2010 (5025 Metric) surface mount package. This component is moisture resistant and operates across the temperature range of -55°C to 155°C. The part maintains Active product status and is ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Equivalent and substitute parts are identified based on matching resistance value, package form factor, and operating temperature range. Substitutes may vary in tolerance specification, power rating, and manufacturer-specific features such as automotive qualification or pulse withstanding capability.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following core parameters:

Mandatory Matching Criteria:

• Resistance value: 220 Ohms
• Package form factor: 2010 (5025 Metric)
• Operating temperature range: -55°C ~ 155°C
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C

Allowable Variations:

• Tolerance: ±1% or ±5% (tighter tolerance is acceptable)
• Power rating: 0.75W (3/4W) or 1W (higher ratings are acceptable)
• Manufacturer-specific features: Automotive AEC-Q200 qualification, moisture resistance, pulse withstanding capability

All substitute parts listed maintain identical physical dimensions (0.197" L x 0.098" W / 5.00mm x 2.50mm) and are ROHS3 compliant with MSL 1 rating.

Parameter Comparison

Engineering Selection Recommendations

Direct Substitutes (Tolerance ±5%, Power 0.75W):

AC2010JK-07220RL and RC2010JK-07220RL are direct functional equivalents with identical tolerance and higher power rating. AC2010JK-07220RL includes Automotive AEC-Q200 qualification. RC2010JK-07220RL maintains moisture resistance without automotive qualification. Both are suitable for applications where the original RC5025J221CS is specified.

Upgraded Substitutes (Tolerance ±1%, Power 0.75W):

AC2010FK-07220RL, RC2010FK-07220RL, and RMCF2010FT220R provide tighter tolerance specification (±1%) with equivalent or higher power rating. AC2010FK-07220RL and RMCF2010FT220R include Automotive AEC-Q200 qualification. These parts are suitable where improved tolerance performance is required.

High Power Substitute (Tolerance ±1%, Power 1W):

RMCP2010FT220R offers the highest power rating (1W) with ±1% tolerance and Automotive AEC-Q200 qualification. This part is suitable for applications requiring enhanced thermal margin or higher power dissipation capability.

Specialized Substitutes (Pulse Withstanding):

CRGS2010J220R and RPC2010JT220R include pulse withstanding capability. RPC2010JT220R additionally includes Automotive AEC-Q200 qualification. These parts are suitable for applications subject to transient voltage or current pulses.

All substitute parts maintain ROHS3 compliance and MSL 1 rating consistent with the original part.

Frequently Asked Questions (FAQ)

Q: Can I substitute RC5025J221CS with a part having ±1% tolerance?

A: Yes. Tighter tolerance (±1%) is acceptable as a substitute for ±5% tolerance. Parts AC2010FK-07220RL, RC2010FK-07220RL, RMCF2010FT220R, and RMCP2010FT220R all provide ±1% tolerance with the same 220 Ohm resistance and 2010 package.

Q: What is the difference between 0.667W and 0.75W power ratings?

A: The 0.75W (3/4W) rating provides higher power dissipation capability than the original 0.667W (2/3W) rating. Substitutes with 0.75W or 1W ratings are acceptable and provide additional thermal margin in the application.

Q: Are all substitute parts ROHS3 compliant?

A: All listed substitute parts are ROHS3 compliant. CRGS2010J220R is listed as RoHS Compliant without specific ROHS3 designation.

Q: What does Automotive AEC-Q200 qualification mean?

A: AEC-Q200 is an automotive industry qualification standard. Parts with this rating (AC2010FK-07220RL, AC2010JK-07220RL, RMCF2010FT220R, RMCP2010FT220R, RPC2010JT220R) are qualified for automotive applications and meet additional reliability and quality requirements.

Q: Can I use RMCP2010FT220R (1W) in place of RC5025J221CS (0.667W)?

A: Yes. The 1W rating provides higher power dissipation capability and is a valid substitute. The 2010 package dimensions, resistance value, operating temperature range, and compliance ratings are identical.

Q: What is the difference between moisture resistant and pulse withstanding features?

A: Moisture resistant indicates protection against moisture ingress. Pulse withstanding indicates the part can tolerate transient overvoltage or overcurrent conditions. These are independent features; a part may have one, both, or neither.

Q: Are the physical dimensions identical across all substitute parts?

A: All parts use the 2010 (5025 Metric) package with dimensions 0.197" L x 0.098" W (5.00mm x 2.50mm). Maximum seated height is 0.026" (0.65mm) for most parts, with RMCF2010FT220R and RMCP2010FT220R at 0.028" (0.70mm) maximum.

Q: Which substitute has the highest inventory availability?

A: RMCP2010FT220R has the highest inventory at 31,949 pieces, followed by RC2010FK-07220RL at 10,378 pieces.
