Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RCS2012F3834CS are identified through strict alignment of the following critical parameters:

Electrical Specifications: Resistance value of 3.83 MOhms, tolerance of ±1%, and power rating of 0.125W (1/8W) must match exactly to ensure functional equivalence in circuit operation.

Package Compatibility: The 0805 (2012 Metric) package format with identical physical dimensions (0.079" L x 0.049" W / 2.00mm x 1.25mm) and two terminations is mandatory for direct PCB footprint compatibility.

Material and Environmental Properties: Thick film composition, temperature coefficient of ±100ppm/°C, and operating temperature range of -55°C to 155°C establish the thermal and environmental performance envelope.

Compliance Standards: ROHS3 compliance and MSL 1 rating ensure regulatory and manufacturing process compatibility across supply chains.

The CRCW08053M83FKEA from Vishay Dale meets all these criteria and qualifies as a direct substitute.
