RC6432F274CS Equivalent & Substitute Parts

Part Overview

The RC6432F274CS is a 270 kOhms ±1% 1W chip resistor manufactured by Samsung Electro-Mechanics in the 2512 (6432 Metric) package format. This thick film, moisture-resistant component operates across a temperature range of -55°C to 155°C and maintains ROHS3 compliance with unlimited moisture sensitivity rating (MSL 1). The part is currently in active production status with 1,078 units available in inventory. Equivalent and substitute parts are identified to support procurement flexibility, design redundancy, and supply chain continuity when the primary component becomes unavailable or when design specifications permit higher performance ratings.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the RC6432F274CS is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 270 kOhms
• Tolerance: ±1%
• Package format: 2512 (6432 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Number of terminations: 2
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity level: 1 (Unlimited)

Allowable Variation:

• Power rating: Substitute parts may exceed the 1W specification, provided the higher rating does not introduce incompatibility with the circuit design or thermal management requirements.

The CRCW2512270KFKEGHP from Vishay Dale meets all mandatory parameters and provides an increased power rating of 1.5W, making it a direct substitute for applications where the additional power handling capacity is acceptable or beneficial.

Engineering Selection Recommendations

RC6432F274CS (Samsung Electro-Mechanics):

• Primary selection for applications requiring exact 1W power specification
• Active production status with established supply availability (1,078 units in stock)
• ROHS3 compliant with unlimited moisture sensitivity rating
• Suitable for standard industrial and consumer applications

CRCW2512270KFKEGHP (Vishay Dale):

• Direct substitute with enhanced 1.5W power rating capability
• Automotive AEC-Q200 qualification provides additional reliability assurance for demanding environments
• Pulse withstanding feature supports transient overvoltage conditions
• Active production status with higher inventory availability (6,592 units in stock)
• Identical electrical and thermal characteristics within specified operating range
• Minimal dimensional variation (0.002" width difference, 0.002" height difference) ensures PCB layout compatibility

Both parts maintain identical resistance, tolerance, temperature coefficient, and operating temperature specifications. Selection between these components depends on application requirements for power margin, automotive qualification, and pulse withstanding capability rather than functional equivalence.

Frequently Asked Questions (FAQ)

Q: Can the CRCW2512270KFKEGHP replace the RC6432F274CS in all applications?

A: Yes, the CRCW2512270KFKEGHP is a direct substitute. The increased 1.5W power rating provides additional thermal margin compared to the 1W specification of the RC6432F274CS. Both components share identical resistance, tolerance, temperature coefficient, and operating temperature range. The minimal dimensional differences (0.002" width and 0.002" height) do not affect PCB footprint compatibility for standard 2512 package designs.

Q: What is the significance of the AEC-Q200 rating on the Vishay part?

A: AEC-Q200 is an automotive qualification standard that certifies component reliability under automotive operating conditions. This certification is not present on the Samsung part. If your application requires automotive-grade components, the CRCW2512270KFKEGHP is the appropriate selection. For non-automotive applications, both parts are functionally equivalent.

Q: Are there dimensional compatibility concerns between these two parts?

A: Dimensional differences are minimal and do not create compatibility issues. The RC6432F274CS measures 0.248" L x 0.126" W with 0.026" maximum seated height. The CRCW2512270KFKEGHP measures 0.248" L x 0.124" W with 0.028" maximum seated height. Both conform to the 2512 (6432 Metric) package standard and use identical two-termination configurations. Standard PCB designs accommodate these variations without modification.

Q: What does the pulse withstanding feature on the Vishay part provide?

A: Pulse withstanding capability indicates the component can tolerate transient overvoltage events without degradation. This feature is beneficial in applications subject to voltage spikes or switching transients. The RC6432F274CS does not specify this feature. Selection depends on whether your circuit design includes transient protection or operates in an environment with potential overvoltage conditions.

Q: Are both parts RoHS3 compliant?

A: Yes, both the RC6432F274CS and CRCW2512270KFKEGHP are ROHS3 compliant and REACH unaffected. Both carry EAR99 export classification. Regulatory compliance is equivalent between the two components.

Q: What is the moisture sensitivity level, and why does it matter?

A: Both parts carry MSL 1 (Unlimited) rating, indicating unlimited shelf life without moisture absorption concerns. This eliminates the need for desiccant packaging or baking procedures prior to assembly. Moisture sensitivity is not a differentiating factor between these components.

Q: Which part should I select for new designs?

A: For new designs, the CRCW2512270KFKEGHP offers advantages including higher power rating, automotive qualification, pulse withstanding capability, and greater inventory availability. The RC6432F274CS remains appropriate if your design specifically requires the 1W specification or if Samsung supply chain preference is established. Both parts are active production components with equivalent electrical performance.
