Parameter Comparison

Engineering Selection Recommendations

RR1220P-4223-D-M (Original Part) The original Susumu component is suitable for applications requiring standard tolerance (±0.5%) thin film resistors with compact form factor. ROHS3 compliance and unlimited MSL rating support general industrial and consumer applications. Operating temperature range extends to 125°C maximum.

5-2176094-3 (TE Connectivity Passive Product) This substitute offers improved tolerance (±0.1%) and increased power rating (0.25W) while maintaining identical footprint. Extended operating temperature to 155°C provides thermal margin. Height increase to 0.026" (0.65mm) requires clearance verification in space-constrained layouts. Suitable for applications requiring tighter tolerance specifications.

ERA-6AEB4223V (Panasonic Electronic Components) This upgrade incorporates Automotive AEC-Q200 qualification, extending applicability to automotive and high-reliability environments. Tolerance specification of ±0.1% and operating temperature to 155°C exceed original part performance. Power rating of 0.125W (1/8W) meets or exceeds application requirements. Height of 0.024" (0.60mm) provides minimal clearance increase over original part.

RN73C2A422KBTDF (TE Connectivity Passive Product) This substitute maintains identical power rating (0.1W) and footprint as the original part while providing superior tolerance (±0.1%) and temperature coefficient (±10ppm/°C). Extended operating temperature to 155°C and height of 0.026" (0.65mm) require layout verification. Optimal for applications requiring precision matching with original electrical specifications.

RT0805BRD07422KL (YAGEO) This substitute provides improved tolerance (±0.1%) and extended operating temperature (155°C) with moderate power rating increase (0.125W). Height of 0.024" (0.60mm) and standard temperature coefficient (±25ppm/°C) align with general industrial requirements. ROHS3 compliance and unlimited MSL rating maintain environmental compatibility.

Frequently Asked Questions (FAQ)

Q: Can I substitute the RR1220P-4223-D-M with any of these parts in my circuit?

A: Substitution is valid when the application requirements do not exceed the original part specifications. All listed substitutes maintain the 422 kOhms resistance value, 0805 package footprint, and thin film construction. Verify that your circuit layout accommodates the maximum height of 0.026" (0.65mm) for some substitutes, compared to the original 0.020" (0.50mm).

Q: What is the significance of tolerance improvement from ±0.5% to ±0.1%?

A: Tighter tolerance (±0.1%) reduces resistance value variation across the component population. For a 422 kOhms resistor, ±0.5% tolerance allows ±2.11 kOhms variation, while ±0.1% tolerance limits variation to ±0.422 kOhms. Applications requiring precise voltage dividers, filter networks, or gain-setting circuits benefit from improved tolerance specifications.

Q: Does the extended operating temperature range of 155°C affect my application?

A: Extended operating temperature range provides thermal margin and does not negatively impact applications designed for the original -55°C ~ 125°C range. Applications operating near 125°C benefit from the additional 30°C margin offered by substitute parts rated to 155°C.

Q: Why do some substitutes have higher power ratings (0.25W vs. 0.1W)?

A: Higher power ratings indicate increased thermal dissipation capability without performance degradation. Applications requiring the original 0.1W rating operate safely with higher-rated substitutes. Power rating selection should match actual circuit power dissipation requirements.

Q: Is the ERA-6AEB4223V suitable for automotive applications?

A: The ERA-6AEB4223V carries Automotive AEC-Q200 qualification, making it suitable for automotive and high-reliability applications. The original RR1220P-4223-D-M does not carry automotive qualification. Automotive application requirements determine whether this upgrade is necessary.

Q: What does the temperature coefficient specification mean?

A: Temperature coefficient (±25ppm/°C or ±10ppm/°C) indicates resistance value change per degree Celsius. The RN73C2A422KBTDF offers superior temperature stability (±10ppm/°C) compared to other substitutes (±25ppm/°C). Applications with stringent temperature stability requirements benefit from lower temperature coefficient values.

Q: Are all substitutes available in Tape & Reel packaging?

A: All listed substitute parts are packaged in Tape & Reel (TR) format, matching the original part packaging. This ensures compatibility with automated assembly processes and standard component handling procedures.

Q: Can I use these substitutes interchangeably on the same PCB assembly?

A: All substitutes maintain identical footprint dimensions (0.079" L x 0.049" W / 2.00mm x 1.25mm) and 0805 package format. Height variations (0.020" to 0.026" maximum seated height) require clearance verification in space-constrained designs. Electrical performance differences (tolerance, temperature coefficient, power rating) do not prevent physical interchangeability.
