Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC2012F3834CS is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

• Resistance value: 3.83 MOhms
• Tolerance: ±1%
• Power rating: 0.125W (1/8W)
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C

Mechanical Equivalence Requirements:

• Package format: 0805 (2012 Metric)
• Number of terminations: 2
• Physical dimensions compatible with 0805 footprint

Compliance Requirements:

• ROHS3 compliance
• Moisture Sensitivity Level 1 or equivalent

The CRCW08053M83FKEA from Vishay Dale meets all electrical and mechanical equivalence criteria. This substitute maintains identical resistance, tolerance, power rating, and temperature specifications while providing automotive-grade AEC-Q200 certification as an additional feature.

Parameter Comparison

Engineering Selection Recommendations

Both the RC2012F3834CS and CRCW08053M83FKEA are active production components with ROHS3 compliance and identical core electrical specifications. Selection between these parts is based on application requirements and supply chain considerations.

The RC2012F3834CS from Samsung Electro-Mechanics provides standard thick film resistor performance with moisture-resistant characteristics and unlimited moisture sensitivity rating.

The CRCW08053M83FKEA from Vishay Dale provides equivalent electrical performance with the addition of AEC-Q200 automotive qualification. This part is suitable for applications requiring automotive-grade component certification. The seated height of 0.020" (0.50mm) is lower than the RC2012F3834CS at 0.026" (0.66mm), which may be relevant for space-constrained PCB designs.

Both parts are suitable for direct substitution in applications where the specified electrical and mechanical parameters are required. Component selection should account for availability, lead time, and any application-specific certification requirements.

Frequently Asked Questions (FAQ)

Q: Can the CRCW08053M83FKEA replace the RC2012F3834CS in any application?

A: Yes, the CRCW08053M83FKEA meets all electrical and mechanical equivalence criteria for the RC2012F3834CS. Both components share identical resistance value, tolerance, power rating, temperature coefficient, and operating temperature range. Both are packaged in the 0805 (2012 Metric) format with compatible footprints and are ROHS3 compliant.

Q: What is the difference in seated height between these two parts?

A: The RC2012F3834CS has a maximum seated height of 0.026" (0.66mm), while the CRCW08053M83FKEA has a maximum seated height of 0.020" (0.50mm). This 0.006" (0.16mm) difference may be relevant for applications with strict height constraints or high-density PCB layouts.

Q: Does the AEC-Q200 rating on the CRCW08053M83FKEA affect compatibility?

A: No. AEC-Q200 is an automotive qualification standard that represents an additional certification level. The presence of AEC-Q200 on the CRCW08053M83FKEA does not affect its compatibility with applications using the RC2012F3834CS. It indicates the part meets automotive reliability standards and may be preferred in automotive applications.

Q: Are both parts available in the same packaging format?

A: Yes. Both the RC2012F3834CS and CRCW08053M83FKEA are supplied in Tape & Reel (TR) packaging and are compatible with standard SMD assembly equipment for the 0805 package format.

Q: What is the moisture sensitivity level for both parts?

A: Both parts have a Moisture Sensitivity Level (MSL) of 1, which indicates unlimited shelf life and no special moisture control requirements during storage or handling.

Q: Are there any compliance differences between these parts?

A: Both parts are ROHS3 compliant and REACH unaffected. Both carry the same ECCN (EAR99) and HTSUS (8533.21.0030) classifications. The primary compliance difference is that the CRCW08053M83FKEA includes AEC-Q200 automotive qualification, which is not present on the RC2012F3834CS.
