Engineering Selection Recommendations

Primary Substitutes (Susumu RG Series - Active Products):

The RG2012N-621-B-T5, RG2012N-621-W-T1, and RG2012N-621-W-T5 are direct functional replacements from Susumu's active product line. These parts maintain identical package geometry, power rating, and operating temperature range while offering improved tolerance specifications (±0.1% and ±0.05% respectively). All retain AEC-Q200 automotive qualification and anti-sulfur coating. Selection among these three depends on tolerance requirements: RG2012N-621-B-T5 for ±0.1% applications, or RG2012N-621-W-T1/W-T5 for ±0.05% precision requirements.

Enhanced Performance Substitutes (Susumu RG2012V Series - Active Products):

The RG2012V series variants (RG2012V-621-B-T5, RG2012V-621-P-T1, RG2012V-621-W-T1, RG2012V-621-W-T5) offer superior temperature coefficient performance at ±5ppm/°C compared to the original ±10ppm/°C specification. These parts are suitable for applications requiring enhanced temperature stability while maintaining all other electrical and mechanical parameters. The RG2012V-621-P-T1 provides the tightest tolerance at ±0.02%.

Cross-Manufacturer Substitute (YAGEO RT Series):

The RT0805WRB07620RL from YAGEO provides electrical equivalence with ±0.05% tolerance and identical power rating. This part does not carry AEC-Q200 automotive qualification and lacks anti-sulfur coating. Selection of this part is appropriate only for non-automotive applications where AEC-Q200 certification is not required.

Higher Power Rating Substitute (Vishay Dale TNPW Series):

The TNPW0805620RBYEA offers increased power dissipation capability at 0.26W compared to the original 0.125W rating, with extended operating temperature range to 175°C. This part maintains AEC-Q200 qualification and anti-sulfur coating. Selection is appropriate for applications requiring higher power handling or extended temperature operation.

Frequently Asked Questions (FAQ)

Q: Can RG2012N-621-B-T5 directly replace RG2012N-621-C-T5?

A: Yes. The RG2012N-621-B-T5 is a direct functional replacement. Both parts share identical 620 Ohm resistance, 0.125W power rating, 0805 package, AEC-Q200 qualification, and operating temperature range. The RG2012N-621-B-T5 offers improved tolerance at ±0.1% compared to the original ±0.25%.

Q: What is the difference between RG2012N and RG2012V series?

A: The primary difference is temperature coefficient performance. RG2012N series has ±10ppm/°C temperature coefficient, while RG2012V series has ±5ppm/°C. Both series maintain identical resistance values, power ratings, package types, and AEC-Q200 qualification. RG2012V is suitable for applications requiring superior temperature stability.

Q: Is the RT0805WRB07620RL suitable for automotive applications?

A: The RT0805WRB07620RL does not carry AEC-Q200 automotive qualification. While electrically equivalent in resistance, tolerance, and power rating, this part is not suitable for automotive applications requiring AEC-Q200 compliance. Use Susumu RG series parts for automotive requirements.

Q: Can TNPW0805620RBYEA be used in place of RG2012N-621-C-T5?

A: The TNPW0805620RBYEA is electrically compatible with identical 620 Ohm resistance and maintains AEC-Q200 qualification. However, it has higher power rating (0.26W vs. 0.125W) and extended operating temperature range (-55°C to 175°C vs. -55°C to 155°C). This part is suitable as a substitute and offers enhanced performance margins for thermal management.

Q: What does the tolerance specification mean for circuit design?

A: Tolerance specifies the maximum deviation from the nominal 620 Ohm value. ±0.25% tolerance allows deviation of ±1.55 Ohms (619.45 to 620.55 Ohms). ±0.1% tolerance allows ±0.62 Ohms (619.38 to 620.62 Ohms). ±0.05% tolerance allows ±0.31 Ohms (619.69 to 620.31 Ohms). Tighter tolerance parts are required for precision analog circuits and measurement applications.

Q: Are all listed substitutes RoHS3 compliant?

A: Yes. All substitute parts listed are RoHS3 compliant and have MSL rating of 1 (Unlimited), matching the original part's environmental compliance status.

Q: What is the significance of the temperature coefficient specification?

A: Temperature coefficient indicates resistance value change per degree Celsius. ±10ppm/°C means the resistance changes by approximately 0.001% per °C. ±5ppm/°C provides half this drift rate. Lower temperature coefficient values are critical for precision applications operating across wide temperature ranges.

Q: Can parts with different packaging codes (T1 vs. T5) be used interchangeably?

A: Yes. The T1 and T5 designations refer to tape reel packaging specifications and do not affect electrical performance or physical package dimensions. Both are 0805 (2012 Metric) packages with identical footprints and can be used interchangeably in circuit designs.
