RC0402J204CS Equivalent & Substitute Parts

Part Overview

The RC0402J204CS is a 200 kOhms ±5% thick film chip resistor manufactured by Samsung Electro-Mechanics in the 01005 (0402 Metric) package format. This component is rated for 0.03W (1/32W) power dissipation with a temperature coefficient of ±250ppm/°C and operates across the -55°C to 125°C temperature range. The part is ROHS3 compliant, REACH unaffected, and carries MSL 1 (Unlimited) moisture sensitivity rating, indicating suitability for standard industrial and consumer applications. As an active product with 1064 units in stock, substitute parts may be required due to design optimization, supply chain considerations, or tolerance specification changes.

Substitute Part Grouping Explanation

Substitution of the RC0402J204CS is permissible with components meeting the following criteria:

Critical Parameters (Must Match):

• Resistance value: 200 kOhms
• Package / Case: 01005 (0402 Metric)
• Power rating: 0.03W (1/32W) minimum
• Composition: Thick Film
• Temperature coefficient: ±250ppm/°C
• Operating temperature range: -55°C ~ 125°C minimum
• Number of terminations: 2
• RoHS compliance: ROHS3 Compliant
• MSL rating: 1 (Unlimited)

Allowable Variation:

• Tolerance: May be tighter (lower value) than ±5% without functional impact
• Moisture resistance feature: Not required for substitution

The CRCW0100200KFREL from Vishay Dale qualifies as a direct substitute based on these parameters, with the distinction of offering improved tolerance specification (±1% versus ±5%).

Parameter Comparison

Engineering Selection Recommendations

Both the RC0402J204CS and CRCW0100200KFREL are active products with ROHS3 compliance and REACH unaffected status, making them suitable for current design implementations. The primary distinction is tolerance specification: the Vishay Dale CRCW0100200KFREL provides ±1% tolerance compared to the Samsung RC0402J204CS at ±5%.

Selection between these parts should be based on circuit tolerance requirements. Applications requiring tighter resistance value control benefit from the CRCW0100200KFREL. Applications with tolerance budgets accommodating ±5% variation may use either part interchangeably. Both components maintain identical electrical performance across the specified operating temperature range and power dissipation envelope.

Frequently Asked Questions (FAQ)

Q: Can the CRCW0100200KFREL replace the RC0402J204CS in existing designs?

A: Yes. The CRCW0100200KFREL is a direct substitute meeting all critical electrical and mechanical parameters. The tighter tolerance (±1% versus ±5%) represents an improvement in specification without introducing incompatibility.

Q: Are there physical compatibility concerns between these parts?

A: No. Both components share identical package dimensions (01005 / 0402 Metric), footprint, and height specifications (0.006" maximum seated height). PCB layout and assembly processes require no modification.

Q: What is the significance of the tolerance difference?

A: Tolerance defines the acceptable range of actual resistance values around the nominal 200 kOhms specification. The RC0402J204CS allows values between 190 kOhms and 210 kOhms (±5%). The CRCW0100200KFREL restricts values to 198 kOhms and 202 kOhms (±1%). Circuits sensitive to resistance variation benefit from the tighter tolerance.

Q: Do both parts meet the same compliance standards?

A: Yes. Both components are ROHS3 compliant, REACH unaffected, carry MSL 1 (Unlimited) moisture sensitivity rating, and share identical ECCN (EAR99) and HTSUS classifications.

Q: Is the moisture resistance feature of the RC0402J204CS critical for substitution?

A: No. Moisture resistance is a feature of the RC0402J204CS but is not a requirement for substitution. The CRCW0100200KFREL operates under identical MSL 1 conditions, indicating equivalent moisture handling capability.

Q: What is the temperature coefficient significance?

A: Both parts share ±250ppm/°C temperature coefficient, meaning resistance value changes by approximately 0.025% per degree Celsius across the -55°C to 125°C operating range. This specification is identical between parts and does not affect substitution decisions.
