Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following criteria:

Mandatory Compatibility Parameters:

• Resistance value: 2.21 kOhms (exact match required)
• Package: 0805 (2012 Metric) (exact match required)
• Composition: Thin Film (exact match required)
• Temperature Coefficient: ±25ppm/°C (exact match required)
• Operating Temperature Range: -55°C minimum and 155°C minimum (equal or exceeding required)
• RoHS Status: ROHS3 Compliant (exact match required)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)

Allowable Variations:

• Tolerance: ±0.25% or tighter (±0.1% acceptable as upgrade)
• Power Rating: 0.25W or higher (0.125W or 0.26W acceptable based on circuit requirements)
• Automotive Rating: AEC-Q200 preferred but not mandatory for all applications
• Manufacturer: Different manufacturers acceptable if all parameters align

All identified substitute parts meet these criteria and are electrically and mechanically interchangeable with the RNCF0805CTE2K21.

Parameter Comparison

Engineering Selection Recommendations

RP73PF2A2K21BTDF (TE Connectivity Passive Product): Direct substitute with improved tolerance (±0.1% vs ±0.25%) and matching 0.25W power rating. Maintains identical operating temperature range. Does not carry AEC-Q200 rating; suitable for non-automotive applications or where automotive qualification is not required.

ERA-6AEB2211V (Panasonic Electronic Components): Upgrade option with ±0.1% tolerance and AEC-Q200 automotive qualification. Power rating reduced to 0.125W; verify circuit power dissipation requirements before selection. Extended inventory availability (23473 units).

RG2012P-2211-B-T5 (Susumu): Upgrade option with ±0.1% tolerance, AEC-Q200 automotive qualification, and anti-sulfur feature. Power rating 0.125W; verify circuit requirements. Lowest profile height (0.020" seated).

RT0805BRD072K21L (YAGEO): Upgrade option with ±0.1% tolerance and 0.125W power rating. Does not carry AEC-Q200 rating. Suitable for general-purpose applications requiring tighter tolerance.

TNPW08052K21BEEA (Vishay Dale): Upgrade option with ±0.1% tolerance, AEC-Q200 automotive qualification, anti-sulfur feature, and moisture-resistant construction. Power rating 0.26W exceeds original specification. Extended operating temperature to 175°C. Suitable for high-reliability automotive applications.

Frequently Asked Questions (FAQ)

Q: Can I use a substitute part with ±0.1% tolerance instead of ±0.25%? A: Yes. Tighter tolerance (±0.1%) is a direct upgrade and maintains full compatibility. The substitute part will perform within the original specification window.

Q: What if my circuit requires the full 0.25W power rating? A: RP73PF2A2K21BTDF and TNPW08052K21BEEA maintain or exceed 0.25W rating. ERA-6AEB2211V, RG2012P-2211-B-T5, and RT0805BRD072K21L are rated at 0.125W; use only if circuit power dissipation does not exceed this limit.

Q: Is AEC-Q200 automotive qualification required for my application? A: AEC-Q200 is mandatory for automotive applications. RNCF0805CTE2K21, ERA-6AEB2211V, RG2012P-2211-B-T5, and TNPW08052K21BEEA carry this rating. RP73PF2A2K21BTDF and RT0805BRD072K21L do not; verify application requirements before substitution.

Q: Are all substitute parts in the same 0805 package? A: Yes. All substitute parts use the 0805 (2012 Metric) package with identical footprint dimensions (0.079" L x 0.049" W). Physical board compatibility is maintained.

Q: What is the difference between these thin film resistors? A: All parts are thin film composition with ±25ppm/°C temperature coefficient. Differences exist in tolerance grade, power rating, automotive qualification, and special features (anti-sulfur, moisture-resistant). Select based on circuit requirements and application environment.

Q: Can I substitute based on inventory availability alone? A: No. Substitution must satisfy all mandatory compatibility parameters. Inventory availability is a secondary consideration after confirming electrical and mechanical compatibility.
