Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC3216F3744CS is determined by strict alignment of the following parameters:

Critical Matching Parameters:

• Resistance value: 3.74 MOhms
• Tolerance: ±1%
• Power rating: 0.25W (1/4W)
• Package: 1206 (3216 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C
• RoHS compliance: ROHS3 Compliant
• MSL rating: 1 (Unlimited)

The CRCW12063M74FKEA from Vishay Dale meets all electrical and mechanical specifications. Both components share identical resistance, tolerance, power rating, package dimensions, and thermal characteristics. Both are ROHS3 compliant with MSL 1 rating. The substitute part includes automotive AEC-Q200 qualification, which represents an additional certification level beyond the base requirements.

Parameter Comparison

Engineering Selection Recommendations

Both the RC3216F3744CS and CRCW12063M74FKEA are active production components with full ROHS3 compliance and REACH unaffected status. Selection between these parts is based on application requirements and supply chain considerations.

The RC3216F3744CS from Samsung Electro-Mechanics is specified with moisture-resistant thick film construction and MSL 1 rating, suitable for general industrial applications with unlimited shelf life under standard storage conditions.

The CRCW12063M74FKEA from Vishay Dale carries AEC-Q200 automotive qualification in addition to identical electrical and mechanical specifications. This part is appropriate for automotive and mission-critical applications requiring automotive-grade component certification. The seated height of 0.024" (0.60mm) is 0.002" lower than the Samsung part, which may be relevant for space-constrained PCB layouts.

Both components are electrically and mechanically interchangeable within the specified parameter ranges. Selection should account for application environment, supply availability, and any automotive or industry-specific qualification requirements.

Frequently Asked Questions (FAQ)

Q: Can CRCW12063M74FKEA replace RC3216F3744CS in any application?

A: Yes, the CRCW12063M74FKEA meets all electrical and mechanical specifications of the RC3216F3744CS. Both components have identical resistance (3.74 MOhms), tolerance (±1%), power rating (0.25W), package (1206), temperature coefficient (±100ppm/°C), and operating range (-55°C ~ 155°C). The substitute part includes AEC-Q200 automotive qualification, which is an additional certification that does not restrict its use in non-automotive applications.

Q: Are there any physical differences between these parts?

A: The seated height differs slightly. The RC3216F3744CS has a maximum seated height of 0.026" (0.66mm), while the CRCW12063M74FKEA is 0.024" (0.60mm). Both parts maintain the same 1206 package footprint (0.126" L x 0.063" W). This height difference may be relevant for applications with strict PCB clearance requirements.

Q: Do both parts have the same moisture sensitivity rating?

A: Yes, both components are rated MSL 1 (Unlimited), indicating unlimited shelf life under standard storage conditions without moisture bake-out requirements.

Q: Are both parts RoHS compliant?

A: Yes, both the RC3216F3744CS and CRCW12063M74FKEA are ROHS3 compliant and REACH unaffected.

Q: What is the difference between the Samsung and Vishay part series designations?

A: The RC3216F3744CS belongs to Samsung's RC series, while the CRCW12063M74FKEA belongs to Vishay Dale's CRCW series. These are manufacturer-specific series designations. The electrical and mechanical specifications are equivalent.

Q: Can I use the Vishay part in automotive applications?

A: The CRCW12063M74FKEA carries AEC-Q200 automotive qualification, making it suitable for automotive applications. The RC3216F3744CS does not carry this specific automotive certification.
