Parameter Comparison

Engineering Selection Recommendations

ERJ-S1DF34R8U (Primary Selection): Active product status with anti-sulfur coating. Recommended for new designs requiring Panasonic sourcing.

CRCW201034R8FKEF (Alternative Selection): Active product status from Vishay Dale. Suitable for applications where multi-source qualification is required. Provides equivalent electrical and mechanical performance.

ERJ-12SF34R8U (Legacy Alternative): Marked as "Not For New Designs" but available in higher inventory (15264 units). Use only in applications where design refresh is not planned or where existing qualification documentation references this part number.

Frequently Asked Questions (FAQ)

Q: Can ERJ-12SF34R8U be used in new designs? A: ERJ-12SF34R8U is designated "Not For New Designs" by the manufacturer. For new designs, use ERJ-S1DF34R8U or CRCW201034R8FKEF.

Q: Are all three parts mechanically identical? A: Yes. All three parts use the 2010 (5025 Metric) package with identical dimensions: 0.197" L x 0.098" W (5.00mm x 2.50mm) and maximum seated height of 0.028" (0.70mm).

Q: Do these parts have the same electrical performance? A: Yes. All three parts share identical electrical specifications: 34.8 Ohms ±1%, 0.75W power rating, ±100ppm/°C temperature coefficient, and -55°C ~ 155°C operating range.

Q: Are all parts AEC-Q200 qualified? A: Yes. All three parts carry AEC-Q200 automotive qualification and are suitable for automotive applications.

Q: What is the difference between ERJ-S1DF34R8U and ERJ-12SF34R8U? A: The primary difference is product status. ERJ-S1DF34R8U is active for new designs and includes anti-sulfur coating. ERJ-12SF34R8U is not recommended for new designs. Electrical and mechanical specifications are identical.

Q: Can I mix these parts in the same production batch? A: Yes, provided your design and qualification documentation permits multi-source components. All three parts meet identical electrical and mechanical parameters and environmental compliance requirements.
