Engineering Selection Recommendations

For Direct Replacement (Obsolete Part Discontinuation):

The RG2012P-621-C-T5 is obsolete and requires substitution. The YAGEO RT0805CRD07620RL provides electrical and mechanical equivalence with identical tolerance (±0.25%) and temperature coefficient (±25ppm/°C) specifications. This part maintains active product status and ROHS3 compliance. However, this part does not carry AEC-Q200 automotive qualification.

For Automotive Applications (AEC-Q200 Required):

The ERA-6AEB621V from Panasonic Electronic Components is an active substitute with AEC-Q200 qualification, improved tolerance (±0.1%), and identical temperature coefficient (±25ppm/°C). This part is suitable for automotive applications requiring automotive-grade components.

For Enhanced Performance (Susumu RG Series Upgrades):

All Susumu RG series upgrade substitutes (RG2012N, RG2012P, RG2012V variants) are active products with AEC-Q200 qualification. Selection among these variants depends on application requirements:

RG2012P-621-B-T5 and RG2012P-621-W-T5 offer improved tolerance with the same temperature coefficient as the original part
RG2012N-621-B-T5 and RG2012N-621-W-T5 provide improved tolerance and reduced temperature coefficient
RG2012V series parts provide the lowest temperature coefficient (±5ppm/°C) with tolerance options ranging from ±0.1% to ±0.02%

All substitute parts maintain identical package dimensions, power rating, operating temperature range, and composition specifications.

Frequently Asked Questions (FAQ)

Q: Can the RG2012P-621-C-T5 be replaced with the YAGEO RT0805CRD07620RL?

A: Yes, the YAGEO RT0805CRD07620RL is electrically and mechanically equivalent with matching 620 Ohms resistance, ±0.25% tolerance, 0.125W power rating, and 0805 package. Both parts have identical temperature coefficients (±25ppm/°C) and operating temperature ranges (-55°C to 155°C). The YAGEO part is active and ROHS3 compliant. However, the YAGEO part does not carry AEC-Q200 automotive qualification, which may be a consideration for automotive applications.

Q: What is the difference between the Susumu RG2012P and RG2012V series substitutes?

A: The primary difference is the temperature coefficient specification. RG2012P series parts have a temperature coefficient of ±25ppm/°C, matching the original RG2012P-621-C-T5. RG2012V series parts have a lower temperature coefficient of ±5ppm/°C, providing superior stability across the operating temperature range. Both series offer improved tolerance options (±0.1%, ±0.05%, or ±0.02%) compared to the original ±0.25% specification. All parts maintain identical package, power rating, and operating temperature range.

Q: Are all substitute parts ROHS3 compliant?

A: Yes, all substitute parts listed are ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited). All parts are REACH unaffected and classified as EAR99 for export control purposes.

Q: Which substitute part offers the tightest tolerance specification?

A: The RG2012V-621-P-T1 offers the tightest tolerance at ±0.02%, combined with the lowest temperature coefficient (±5ppm/°C). This part is suitable for precision applications requiring minimal resistance variation across temperature and time.

Q: Can substitute parts be used interchangeably in existing designs?

A: Substitute parts with identical or improved specifications are mechanically and electrically compatible. Parts with tighter tolerance and lower temperature coefficient provide enhanced performance without design modification. The 0805 package dimensions are identical across all listed parts, ensuring PCB footprint compatibility.

Q: What is the inventory status of substitute parts?

A: All Susumu RG series substitutes and the Panasonic ERA-6AEB621V are active products with current inventory availability. The YAGEO RT0805CRD07620RL is also active with available stock. Specific inventory quantities should be verified with the component supplier for procurement planning.

Q: Is AEC-Q200 qualification required for my application?

A: AEC-Q200 qualification is required for automotive applications. The original RG2012P-621-C-T5, all Susumu RG series substitutes, and the Panasonic ERA-6AEB621V carry AEC-Q200 qualification. The YAGEO RT0805CRD07620RL does not carry this qualification and is not suitable for automotive applications requiring automotive-grade components.
