RVC1206FT576K Equivalent & Substitute Parts

Part Overview

The RVC1206FT576K is a 576 kOhms ±1% 0.25W chip resistor in 1206 (3216 Metric) package manufactured by Stackpole Electronics Inc. This thick film resistor is designed for general-purpose applications requiring precision resistance values with standard industrial temperature range operation. The part is currently in active production status with ROHS3 compliance and unlimited moisture sensitivity rating.

Substitute parts become necessary when primary inventory is unavailable, when application-specific certifications are required (such as automotive qualification), or when design requirements mandate enhanced reliability standards. Alternative equivalent parts maintain the core electrical specifications while potentially offering different manufacturing series, enhanced features, or expanded availability.

Substitute Part Grouping Explanation

Substitution eligibility for the RVC1206FT576K is determined by strict adherence to the following electrical and mechanical parameters:

Primary Substitution Criteria:

• Resistance value: 576 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.25W minimum
• Package: 1206 (3216 Metric) form factor
• Composition: Thick film construction
• Temperature coefficient: ±100ppm/°C or better
• Operating temperature range: -55°C to 155°C minimum
• RoHS compliance: ROHS3 or equivalent

The RMCF1206FT576K qualifies as a direct substitute while maintaining identical electrical specifications. This part is manufactured by the same supplier and shares the same core resistance, tolerance, power rating, and package specifications. The RMCF series adds automotive AEC-Q200 qualification, making it suitable for applications requiring enhanced reliability and automotive-grade component standards.

Parameter Comparison

Engineering Selection Recommendations

The RVC1206FT576K and RMCF1206FT576K are electrically and mechanically equivalent for applications operating within the specified temperature range and power constraints. Both parts maintain identical resistance, tolerance, and thermal characteristics.

Selection between these parts depends on application requirements:

RVC1206FT576K is appropriate for general industrial and consumer applications where standard component qualification is sufficient and cost optimization is a priority.

RMCF1206FT576K is required for automotive applications, transportation systems, or any design requiring AEC-Q200 qualification. This automotive-grade variant provides enhanced reliability screening and qualification documentation necessary for automotive supply chains.

Both parts are active production items with established supply chains. The choice between them should be based solely on whether automotive-grade certification is mandated by the application specification or end-use environment.

Frequently Asked Questions (FAQ)

Q: Can RMCF1206FT576K be used as a direct replacement for RVC1206FT576K?

A: Yes. The RMCF1206FT576K maintains identical electrical specifications (576 kOhms ±1%, 0.25W) and package form factor (1206). The primary difference is the addition of automotive AEC-Q200 qualification in the RMCF series. This makes it a compatible substitute for any application where the RVC part was originally specified.

Q: What is the significance of the AEC-Q200 rating on the RMCF series?

A: AEC-Q200 is an automotive industry qualification standard that certifies component reliability under automotive operating conditions. This certification is required for components used in automotive applications but is not necessary for general industrial or consumer electronics applications.

Q: Are there dimensional differences between RVC1206FT576K and RMCF1206FT576K?

A: Both parts use the 1206 (3216 Metric) package. Minor dimensional variations exist within standard package tolerances: RVC dimensions are 0.122" L x 0.061" W (3.10mm x 1.55mm) with 0.026" max height, while RMCF dimensions are 0.126" L x 0.063" W (3.20mm x 1.60mm) with 0.028" max height. These variations remain within standard 1206 package specifications and do not affect PCB layout or assembly compatibility.

Q: What does ±100ppm/°C temperature coefficient mean for this resistor?

A: The temperature coefficient specifies how much the resistance value changes with temperature. ±100ppm/°C means the resistance can vary by up to 100 parts per million per degree Celsius across the operating temperature range of -55°C to 155°C. For a 576 kOhm resistor, this represents a maximum change of approximately 5.76 ohms per degree Celsius.

Q: Are both parts RoHS compliant?

A: Yes. Both RVC1206FT576K and RMCF1206FT576K are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic components.
