Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RNCF0805FTD2K21 is determined by strict equivalence across the following parameters:

• Resistance value: 2.21 kOhms
• Tolerance: ±1%
• Power rating: 0.25W
• Package type: 0805 (2012 Metric)
• Composition: Thin Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity: MSL 1

The RNCP0805FTD2K21 meets all substitution criteria. While the RNCF series features AEC-Q200 automotive qualification and the RNCP series features anti-sulfur composition, both parts maintain identical electrical specifications, package dimensions, and environmental ratings required for direct substitution.

Parameter Comparison

Engineering Selection Recommendations

Both the RNCF0805FTD2K21 and RNCP0805FTD2K21 are active production components from Stackpole Electronics Inc with full RoHS3 compliance and REACH unaffected status. The RNCF series carries AEC-Q200 automotive qualification, while the RNCP series incorporates anti-sulfur composition. Selection between these parts depends on application requirements: choose RNCF0805FTD2K21 when AEC-Q200 automotive qualification is mandatory; choose RNCP0805FTD2K21 when anti-sulfur protection is required or when the RNCF variant is unavailable. Both parts are electrically and mechanically interchangeable within the specified parameters.

Frequently Asked Questions (FAQ)

Q: Can RNCP0805FTD2K21 be used as a direct replacement for RNCF0805FTD2K21?

A: Yes. Both parts share identical resistance (2.21 kOhms), tolerance (±1%), power rating (0.25W), package (0805), composition (thin film), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C to 155°C). The primary difference is that RNCF includes AEC-Q200 automotive qualification while RNCP includes anti-sulfur features. Substitution is valid when application requirements do not mandate AEC-Q200 certification.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both parts have identical length (0.079" / 2.00mm) and width (0.049" / 1.25mm). Maximum seated height is 0.026" (0.65mm) for RNCF0805FTD2K21 and 0.025" (0.65mm) for RNCP0805FTD2K21, representing a negligible difference that does not affect PCB layout or assembly compatibility.

Q: What is the difference between AEC-Q200 qualification and anti-sulfur composition?

A: AEC-Q200 is an automotive qualification standard ensuring reliability under automotive operating conditions. Anti-sulfur composition protects against sulfur-induced corrosion in high-sulfur environments. These are distinct features; RNCF0805FTD2K21 provides automotive qualification while RNCP0805FTD2K21 provides environmental protection. Application requirements determine which feature is necessary.

Q: Are both parts RoHS compliant?

A: Yes. Both RNCF0805FTD2K21 and RNCP0805FTD2K21 are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: Can these parts be used interchangeably in automotive applications?

A: RNCF0805FTD2K21 carries explicit AEC-Q200 automotive qualification. RNCP0805FTD2K21 does not list AEC-Q200 qualification. For applications requiring AEC-Q200 certification, use RNCF0805FTD2K21. For non-certified automotive or general industrial applications, RNCP0805FTD2K21 is electrically and mechanically compatible.
