RC0603J100CS Equivalent & Substitute Parts

Part Overview

The RC0603J100CS is a 10 Ohm ±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 currently in stock with 8591 pieces available as new original inventory.

Substitute parts become necessary when the primary manufacturer part experiences supply constraints, extended lead times, or when design flexibility permits component sourcing from alternative manufacturers while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC0603J100CS is determined by strict equivalence across the following critical parameters:

Electrical Parameters (Must Match Exactly):

• Resistance value: 10 Ohms
• Tolerance: ±5%
• Power rating: 0.05W (1/20W)
• Temperature coefficient: ±250ppm/°C
• Operating temperature range: -55°C ~ 125°C

Mechanical Parameters (Must Match Exactly):

• Package designation: 0201 (0603 Metric)
• Physical dimensions: 0.024" L x 0.012" W (0.60mm x 0.30mm)
• Maximum seated height: 0.010" (0.26mm)
• Number of terminations: 2

Regulatory & Compliance Parameters (Must Match or Exceed):

• RoHS3 Compliance required
• MSL 1 (Unlimited) acceptable
• REACH Unaffected status acceptable

The MCR006YRTJ100 manufactured by Rohm Semiconductor meets all specified electrical, mechanical, and regulatory requirements and qualifies as a direct substitute.

Engineering Selection Recommendations

RC0603J100CS (Samsung Electro-Mechanics) - Primary Selection

The RC0603J100CS maintains Active product status with confirmed inventory of 8591 pieces available as new original stock. This part is the preferred selection for new designs and production runs where supply availability is not constrained. Full RoHS3 compliance and MSL 1 rating support unrestricted handling and storage protocols.

MCR006YRTJ100 (Rohm Semiconductor) - Substitute Selection

The MCR006YRTJ100 is classified as Discontinued at DiGi Electronics, indicating limited future availability through standard distribution channels. This part is suitable for substitution only when RC0603J100CS supply is unavailable. All electrical, mechanical, and regulatory parameters are equivalent, supporting direct pin-for-pin and footprint-compatible replacement. Inventory availability is 3417 pieces as new original stock. RoHS3 compliance and MSL 1 rating are maintained.

Both parts are suitable for applications requiring 10 Ohm ±5% thick film resistors in 0201 package format with -55°C to 125°C operating temperature range.

Frequently Asked Questions (FAQ)

Q: Can MCR006YRTJ100 be used as a direct replacement for RC0603J100CS in existing designs?

A: Yes. The MCR006YRTJ100 is electrically and mechanically equivalent across all specified parameters. Footprint compatibility is identical, and no circuit modifications are required. Both parts meet RoHS3 compliance and MSL 1 requirements.

Q: What is the significance of the 0201 (0603 Metric) package designation?

A: The 0201 package is the metric designation for this resistor size, measuring 0.60mm x 0.30mm. The parenthetical "0603 Metric" refers to the metric equivalent of the imperial 0201 designation. This package size is standardized across both manufacturers and ensures mechanical compatibility with PCB footprints designed for this component class.

Q: Are there differences in moisture sensitivity handling between these parts?

A: No. Both RC0603J100CS and MCR006YRTJ100 carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions. Standard handling procedures apply without special baking or desiccant storage requirements.

Q: Why is MCR006YRTJ100 listed as discontinued?

A: The MCR006YRTJ100 is discontinued at DiGi Electronics, indicating this distributor no longer carries the part in active inventory. However, 3417 pieces remain available as new original stock through current inventory channels. Discontinuation status does not affect electrical or mechanical performance for existing applications.

Q: What parameters must remain identical for substitution eligibility?

A: Resistance value (10 Ohms), tolerance (±5%), power rating (0.05W), package type (0201), physical dimensions (0.024" x 0.012"), temperature coefficient (±250ppm/°C), and operating temperature range (-55°C ~ 125°C) must all match exactly. RoHS3 compliance and MSL 1 rating must be maintained or exceeded.

Q: Can these parts be used interchangeably in high-precision applications?

A: Both parts share identical tolerance (±5%) and temperature coefficient (±250ppm/°C) specifications. Application suitability depends on circuit-level tolerance requirements, not on manufacturer differences. Substitution does not introduce additional precision variations.
