RC0603J911CS Equivalent & Substitute Parts

Part Overview

The RC0603J911CS is a 910 Ohms ±5% thick film chip resistor manufactured by Samsung Electro-Mechanics, rated at 0.05W (1/20W) in a 0201 (0603 Metric) surface mount package. This component is classified as Active product status with full RoHS3 compliance and unlimited moisture sensitivity level (MSL 1). The part is designed for applications requiring moisture-resistant thick film construction across industrial and commercial temperature ranges (-55°C to 125°C).

Substitute parts are identified when equivalent electrical specifications, mechanical dimensions, and environmental compliance parameters align with the main part, enabling direct replacement in circuit designs without functional degradation.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC0603J911CS is determined by the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 910 Ohms
• Package / Case: 0201 (0603 Metric)
• Power rating: 0.05W (1/20W) minimum
• Composition: Thick Film
• Operating temperature range: -55°C to 125°C minimum
• RoHS3 compliance
• Moisture Sensitivity Level: 1 (Unlimited)

Allowable Variation:

• Tolerance: ±5% or tighter (±1% is acceptable as a superior specification)
• Temperature coefficient: ±250ppm/°C or equivalent

The MCR006YRTF9100 from Rohm Semiconductor qualifies as a substitute part. While it specifies a tighter tolerance of ±1% compared to the main part's ±5%, this represents an improvement in precision and does not compromise compatibility. All other electrical, mechanical, and environmental parameters remain equivalent.

Engineering Selection Recommendations

RC0603J911CS (Samsung Electro-Mechanics) - Primary Part

The RC0603J911CS maintains Active product status with 700 pieces in current inventory. This part is suitable for applications where ±5% tolerance meets circuit requirements and moisture-resistant thick film construction is specified. Full RoHS3 compliance and unlimited MSL rating support deployment in standard industrial and commercial environments.

MCR006YRTF9100 (Rohm Semiconductor) - Substitute Part

The MCR006YRTF9100 is classified as Discontinued at DiGi Electronics but remains available with 10,302 pieces in inventory. This substitute provides identical electrical and mechanical performance with the advantage of ±1% tolerance, offering superior precision for applications sensitive to resistance value variation. RoHS3 compliance and unlimited MSL rating ensure environmental and regulatory compatibility. The tighter tolerance specification does not introduce incompatibility; it represents an enhanced specification suitable for precision-critical circuits.

Both parts share identical package dimensions, thermal characteristics, and compliance certifications, enabling direct substitution at the PCB assembly level without design modification.

Frequently Asked Questions (FAQ)

Q: Can MCR006YRTF9100 directly replace RC0603J911CS in existing designs?

A: Yes. Both parts share identical 0201 (0603 Metric) package dimensions, power ratings, operating temperature ranges, and compliance certifications. The MCR006YRTF9100's ±1% tolerance is tighter than the RC0603J911CS's ±5% tolerance, making it functionally compatible and suitable for direct substitution without PCB redesign.

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

A: Tolerance defines the allowable deviation from the nominal 910 Ohm resistance value. The RC0603J911CS allows deviation between 864.5 and 955.5 Ohms. The MCR006YRTF9100 restricts deviation between 900.9 and 919.1 Ohms. For applications requiring tighter resistance control, the MCR006YRTF9100 provides superior precision. For applications with ±5% tolerance specifications, both parts are acceptable.

Q: Are the physical dimensions identical?

A: Yes. Both parts measure 0.024" L x 0.012" W (0.60mm x 0.30mm) with a maximum seated height of 0.010" (0.26mm). They are mechanically interchangeable on PCB layouts designed for 0201 (0603 Metric) packages.

Q: Do both parts meet the same environmental and regulatory standards?

A: Yes. Both RC0603J911CS and MCR006YRTF9100 are RoHS3 compliant, REACH unaffected, classified as EAR99, and share the same HTSUS code (8533.21.0030). Both maintain Moisture Sensitivity Level 1 (Unlimited), indicating no special moisture handling requirements during storage or assembly.

Q: What is the difference in packaging between the two parts?

A: The RC0603J911CS is supplied in Tape & Reel (TR) format, while the MCR006YRTF9100 is supplied in Cut Tape (CT) & Digi-Reel® format. Both packaging formats are standard for 0201 chip resistors and do not affect component performance or compatibility.

Q: Why is MCR006YRTF9100 listed as discontinued?

A: The MCR006YRTF9100 is discontinued at DiGi Electronics as a distributor, but the part remains available through inventory. Discontinuation at a specific distributor does not indicate product obsolescence; alternative sources and inventory remain accessible for procurement.
