Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RCS0603J435CS is determined by strict equivalence across the following critical parameters:

Electrical Specifications: Resistance value (4.3 MOhms), tolerance (±5%), and power rating (0.05W) must be identical. Temperature coefficient (±250ppm/°C) and operating temperature range (-55°C ~ 125°C) must match or exceed the original specification.

Package Compatibility: The 0201 (0603 Metric) package format with dimensions 0.024" L x 0.012" W (0.60mm x 0.30mm) is mandatory for PCB footprint compatibility. Height seated maximum of 0.010" (0.25mm) ensures mechanical clearance requirements are met.

Composition and Construction: Thick film construction is required. Environmental features such as anti-sulfur and moisture-resistant properties are considered equivalent when the base composition and performance characteristics match.

Compliance and Certifications: RoHS3 compliance, MSL Level 1 (Unlimited), and REACH Unaffected status ensure regulatory and environmental compatibility.

The MCR006YRTJ435 manufactured by Rohm Semiconductor meets all substitution criteria and is classified as an equivalent part.

Parameter Comparison

Engineering Selection Recommendations

The MCR006YRTJ435 from Rohm Semiconductor is electrically and mechanically equivalent to the RCS0603J435CS. Both parts satisfy identical electrical requirements, package specifications, and environmental compliance standards. The MCR006YRTJ435 is currently discontinued at DiGi Electronics; however, inventory availability of 14,791 units indicates alternative distribution channels may maintain stock. Selection between these parts should be based on supply chain availability, lead time requirements, and procurement cost considerations. Both parts carry ROHS3 compliance and REACH Unaffected status, ensuring regulatory compatibility in end-use applications.

Frequently Asked Questions (FAQ)

Q: Can the MCR006YRTJ435 be used as a direct replacement for the RCS0603J435CS?

A: Yes. Both parts are electrically identical with matching resistance (4.3 MOhms), tolerance (±5%), power rating (0.05W), and temperature characteristics (±250ppm/°C, -55°C ~ 125°C). Package dimensions and height specifications are equivalent, enabling direct PCB footprint compatibility.

Q: Are there any differences in physical dimensions between these parts?

A: Both parts use the 0201 (0603 Metric) package with dimensions 0.024" L x 0.012" W (0.60mm x 0.30mm). The seated height maximum differs slightly: RCS0603J435CS is 0.010" (0.25mm) and MCR006YRTJ435 is 0.010" (0.26mm). This 0.01mm difference does not affect PCB assembly or clearance requirements.

Q: What is the significance of the MSL Level 1 rating?

A: MSL Level 1 (Unlimited) indicates unlimited shelf life without moisture baking requirements. Both parts can be stored and handled without time-sensitive moisture sensitivity constraints, simplifying inventory management and procurement logistics.

Q: Are both parts RoHS compliant?

A: Yes. Both the RCS0603J435CS and MCR006YRTJ435 are ROHS3 compliant and REACH Unaffected, meeting current environmental and regulatory requirements for electronic component manufacturing and use.

Q: Why is the MCR006YRTJ435 listed as discontinued?

A: The MCR006YRTJ435 is discontinued at DiGi Electronics as a distribution channel; however, this does not indicate manufacturer discontinuation. Rohm Semiconductor may continue production through alternative distributors. Inventory availability should be verified through current supply chain channels.
