RC0603J200CS Equivalent & Substitute Parts

Part Overview

The RC0603J200CS is a 20 Ohm ±5% thick film chip resistor manufactured by Samsung Electro-Mechanics, rated at 0.05W (1/20W) in a 0201 (0603 Metric) package. This component is classified as Active product status with full RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1). The part is supplied in Tape & Reel packaging format.

Substitute parts become necessary when the primary part experiences supply constraints, extended lead times, or when design requirements permit tolerance or packaging format variations. The MCR006YRTF20R0 from Rohm Semiconductor serves as a direct functional equivalent, though with modified tolerance and packaging specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC0603J200CS is determined by the following mandatory parameters:

Electrical Compatibility Requirements:

• Resistance value: 20 Ohms (exact match required)
• Power rating: 0.05W minimum (equal or higher acceptable)
• Temperature coefficient: ±250ppm/°C or better
• Operating temperature range: Must encompass -55°C ~ 125°C

Mechanical Compatibility Requirements:

• Package / Case: 0201 (0603 Metric) form factor (exact match required)
• Physical dimensions: 0.024" L x 0.012" W (0.60mm x 0.30mm)
• Number of terminations: 2 (exact match required)

Compliance Requirements:

• RoHS3 compliance mandatory
• Moisture Sensitivity Level: 1 (Unlimited) or equivalent

Tolerance Variation: Tolerance may vary from ±5% to tighter specifications (±1% or better) without affecting substitution validity, as tighter tolerance represents improved performance. Looser tolerance specifications are not acceptable substitutes.

Packaging Format: Packaging format (Tape & Reel vs. Cut Tape) does not affect electrical or mechanical compatibility but may impact procurement and assembly processes.

The MCR006YRTF20R0 meets all mandatory electrical, mechanical, and compliance requirements with the exception of tighter tolerance (±1% vs. ±5%) and different packaging format (Cut Tape vs. Tape & Reel).

Engineering Selection Recommendations

Primary Selection: RC0603J200CS

The RC0603J200CS maintains Active product status with confirmed availability (792 Pcs in stock). This part is the preferred choice for new designs and production applications requiring long-term supply assurance. Full RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1) support deployment in standard manufacturing environments without special handling requirements.

Substitute Selection: MCR006YRTF20R0

The MCR006YRTF20R0 is electrically and mechanically compatible with the RC0603J200CS. However, this part is listed as Discontinued at DiGi Electronics, which restricts its viability for ongoing production. The tighter tolerance specification (±1% vs. ±5%) represents improved performance characteristics and may be advantageous in precision applications, but this benefit is offset by supply discontinuation status.

Compliance Considerations:

Both parts maintain ROHS3 compliance and identical environmental ratings (MSL 1, REACH Unaffected, ECCN EAR99). No compliance barriers exist for substitution from a regulatory perspective.

Packaging Format Impact:

The RC0603J200CS is supplied in Tape & Reel format, optimized for automated assembly processes. The MCR006YRTF20R0 is supplied in Cut Tape format, which may require manual handling or alternative feeder compatibility depending on assembly equipment configuration.

Frequently Asked Questions (FAQ)

Q: Can the MCR006YRTF20R0 be used as a direct replacement for the RC0603J200CS in existing designs?

A: Yes, from an electrical and mechanical standpoint. Both parts share identical resistance (20 Ohms), power rating (0.05W), package dimensions (0201 / 0603 Metric), temperature range (-55°C ~ 125°C), and compliance certifications. The MCR006YRTF20R0 features tighter tolerance (±1% vs. ±5%), which does not create compatibility issues. However, the discontinued status of the MCR006YRTF20R0 makes it unsuitable for production applications requiring sustained supply.

Q: What is the significance of the tolerance difference between ±5% and ±1%?

A: Tolerance defines the acceptable deviation from the nominal 20 Ohm resistance value. The RC0603J200CS allows deviation between 19 Ohms and 21 Ohms (±5%). The MCR006YRTF20R0 restricts deviation to between 19.8 Ohms and 20.2 Ohms (±1%). Tighter tolerance represents improved precision and is acceptable as a substitute. Applications requiring the looser ±5% tolerance can use either part without performance degradation.

Q: Are there packaging compatibility concerns when substituting between Tape & Reel and Cut Tape formats?

A: Packaging format affects procurement and assembly logistics but not electrical or mechanical compatibility. Tape & Reel (TR) format is optimized for automated pick-and-place assembly equipment. Cut Tape (CT) format requires manual handling or alternative feeder systems. Substitution is feasible only if assembly equipment can accommodate the different packaging format.

Q: What is Moisture Sensitivity Level (MSL) 1, and why is it important?

A: MSL 1 (Unlimited) indicates the component can be stored indefinitely without special moisture control measures. Both the RC0603J200CS and MCR006YRTF20R0 carry this rating, eliminating moisture-related handling constraints during storage and assembly.

Q: Why is the RC0603J200CS preferred despite the MCR006YRTF20R0 having tighter tolerance?

A: The RC0603J200CS maintains Active product status with confirmed inventory availability (792 Pcs in stock), ensuring reliable long-term supply for production applications. The MCR006YRTF20R0 is discontinued at DiGi Electronics, creating supply uncertainty. While the tighter tolerance of the MCR006YRTF20R0 offers marginal performance benefits, supply discontinuation makes it unsuitable for designs requiring sustained component availability.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the RC0603J200CS and MCR006YRTF20R0 are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic component manufacturing and deployment.
