Substitute Part Grouping Explanation
Substitution of the RG1608P-623-C-T5 is determined by strict equivalence across the following parameters:
Mandatory Compatibility Parameters:
- Resistance value: 62 kOhms (exact match required)
- Package type: 0603 (1608 Metric) (physical and electrical footprint compatibility)
- Power rating: 0.1W minimum (equal or greater capacity acceptable)
- Composition: Thin film (electrical performance characteristics)
- Operating temperature range: -55°C to 155°C minimum (or equivalent)
- RoHS3 compliance (regulatory requirement)
- Moisture Sensitivity Level 1 (handling and storage compatibility)
Tolerance Considerations: Substitutes with equal or tighter tolerance specifications (±0.25%, ±0.1%, ±0.05%) are functionally equivalent. Tighter tolerance parts provide improved circuit performance without design modification.
Temperature Coefficient: Temperature coefficient variations (±25ppm/°C, ±15ppm/°C, ±10ppm/°C) do not preclude substitution but affect circuit stability across temperature extremes.
Automotive Qualification: AEC-Q200 certification is maintained across all substitute options, ensuring reliability for automotive and high-reliability applications.

Engineering Selection Recommendations
Primary Substitutes (Susumu RG Series - Same Manufacturer):
RG1608P-623-B-T5 is the direct active equivalent with identical tolerance (±0.25%) and temperature coefficient (±25ppm/°C) to the obsolete RG1608P-623-C-T5. This part maintains full AEC-Q200 automotive qualification and is available in high inventory (31,613 pieces). Selection of this part eliminates any design verification requirements.
RG1608N-623-B-T5 and RG1608N-623-W-T5 offer improved tolerance specifications (±0.1% and ±0.05% respectively) with superior temperature coefficient performance (±10ppm/°C). Both maintain AEC-Q200 qualification and are active products suitable for designs requiring enhanced precision.
Secondary Substitutes (Panasonic ERA-3A Series - Cross-Manufacturer):
ERA-3APB623V provides the highest inventory availability (29,285 pieces) among all alternatives with ±0.1% tolerance and AEC-Q200 qualification. Temperature coefficient of ±15ppm/°C represents intermediate performance between the original part and higher-precision alternatives.
ERA-3ARB623V and ERA-3ARW623V offer superior temperature coefficient performance (±10ppm/°C and ±10ppm/°C respectively) with AEC-Q200 qualification. ERA-3ARW623V provides the tightest tolerance (±0.05%) among Panasonic options.
Tertiary Substitute (YAGEO RT Series - Cross-Manufacturer):
RT0603CRD0762KL matches the original tolerance specification (±0.25%) and temperature coefficient (±25ppm/°C) but lacks AEC-Q200 automotive qualification. This part is suitable only for non-automotive applications where AEC-Q200 certification is not required. Operating temperature range is -55°C to 155°C, matching the original specification.
Vishay MCT Series Consideration:
MCT06030D6202BP500 provides ±0.1% tolerance with anti-sulfur coating but operates only to 125°C maximum, limiting its use to applications not requiring the full -55°C to 155°C range of the original part. This part lacks AEC-Q200 certification.
Frequently Asked Questions (FAQ)
Q: Can RG1608P-623-B-T5 directly replace RG1608P-623-C-T5 without circuit redesign?
A: Yes. RG1608P-623-B-T5 is electrically and mechanically equivalent with identical resistance (62 kOhms), tolerance (±0.25%), power rating (0.1W), package (0603), and operating temperature range (-55°C to 155°C). Both parts maintain AEC-Q200 qualification and anti-sulfur coating. No design modification is required.
Q: What is the difference between Susumu RG1608N and RG1608P series designations?
A: The RG1608N series offers improved temperature coefficient performance (±10ppm/°C) compared to RG1608P series (±25ppm/°C). Both series maintain identical resistance values, power ratings, and package specifications. Selection depends on circuit stability requirements across the operating temperature range.
Q: Are Panasonic ERA-3A parts suitable for automotive applications?
A: Yes. ERA-3AEB623V, ERA-3APB623V, ERA-3ARB623V, and ERA-3ARW623V all carry AEC-Q200 automotive qualification. These parts are suitable for automotive and high-reliability applications equivalent to the original Susumu part.
Q: Why does MCT06030D6202BP500 have a lower maximum operating temperature?
A: MCT06030D6202BP500 operates to 125°C maximum, compared to 155°C for the original part. This limitation restricts its use to applications where the full temperature range is not required. For designs requiring operation to 155°C, Susumu or Panasonic alternatives are required.
Q: Can I use a ±0.05% tolerance part (RG1608N-623-W-T5 or ERA-3ARW623V) as a direct replacement?
A: Yes. Tighter tolerance specifications are functionally equivalent and provide improved circuit performance. A ±0.05% part meets all requirements of a ±0.25% specification. No design modification is necessary, and circuit accuracy will improve.
Q: What is the significance of the temperature coefficient difference between ±25ppm/°C and ±10ppm/°C?
A: Temperature coefficient defines resistance change per degree Celsius. A ±10ppm/°C part exhibits half the resistance drift of a ±25ppm/°C part across temperature extremes. For circuits sensitive to resistance variation (precision analog circuits, reference networks), lower temperature coefficient improves stability. For general-purpose applications, both specifications are acceptable.
Q: Is the YAGEO RT0603CRD0762KL suitable for automotive applications?
A: No. RT0603CRD0762KL lacks AEC-Q200 automotive qualification. This part is suitable only for consumer and industrial applications where automotive certification is not required. For automotive designs, Susumu RG or Panasonic ERA-3A series parts are required.
Q: What does MSL 1 (Unlimited) moisture sensitivity mean?
A: MSL 1 indicates the component requires no special moisture protection during storage or handling. All substitute parts listed carry MSL 1 rating, ensuring identical handling and storage requirements.
Q: Can I mix different substitute parts in the same production run?
A: Yes, provided all parts meet the circuit's electrical requirements. All listed substitutes maintain 62 kOhms resistance, 0.1W power rating, 0603 package, and -55°C to 155°C operating range. Tolerance and temperature coefficient variations do not preclude interchangeability. For designs requiring AEC-Q200 certification, use only parts carrying this qualification.
