Engineering Selection Recommendations

All listed substitute parts maintain active product status and ROHS3 compliance. Selection between substitutes should be based on the following factors:

RT0603BRD0752K3L (YAGEO): Offers improved tolerance (±0.1%) and reduced temperature coefficient (±25ppm/°C) compared to the original specification. Suitable for applications requiring tighter resistance accuracy.

RT0603DRE0752K3L (YAGEO): Provides intermediate tolerance (±0.5%) with standard temperature coefficient (±50ppm/°C). Maintains original temperature coefficient performance while improving tolerance.

6-2176089-4 (TE Connectivity): Delivers ±0.1% tolerance and ±25ppm/°C temperature coefficient with higher power rating (0.167W). Applicable where increased power dissipation capability is beneficial.

ERA-3AEB5232V (Panasonic): Combines ±0.1% tolerance with AEC-Q200 automotive qualification. Suitable for automotive and high-reliability applications requiring automotive-grade components.

RG1608P-5232-B-T5 (Susumu): Provides ±0.1% tolerance, AEC-Q200 automotive qualification, and anti-sulfur protection. Recommended for automotive applications in corrosive environments or where enhanced reliability is required.

Frequently Asked Questions (FAQ)

Q: Can RT0603BRD0752K3L replace RT0603FRE0752K3L directly?

A: Yes. Both parts share identical resistance (52.3 kOhms), package (0603), power rating (0.1W), and operating temperature range (-55°C ~ 155°C). RT0603BRD0752K3L offers improved tolerance (±0.1% versus ±1%) and lower temperature coefficient (±25ppm/°C versus ±50ppm/°C), making it a direct upgrade.

Q: What is the difference between RT0603DRE0752K3L and RT0603BRD0752K3L?

A: Both parts are manufactured by YAGEO with 52.3 kOhms resistance and 0.1W power rating. RT0603BRD0752K3L offers ±0.1% tolerance with ±25ppm/°C temperature coefficient, while RT0603DRE0752K3L provides ±0.5% tolerance with ±50ppm/°C temperature coefficient. RT0603BRD0752K3L delivers superior accuracy and stability.

Q: Is 6-2176089-4 compatible with the original part?

A: Yes. The TE Connectivity part 6-2176089-4 maintains the same resistance value, package, and operating temperature range. It features ±0.1% tolerance and higher power rating (0.167W versus 0.1W), providing enhanced performance margin.

Q: What does AEC-Q200 qualification mean?

A: AEC-Q200 is an automotive electronics qualification standard. ERA-3AEB5232V and RG1608P-5232-B-T5 meet this standard, indicating suitability for automotive applications with enhanced reliability requirements and environmental stress testing.
