Parameter Comparison

Engineering Selection Recommendations

All three parts meet the specified electrical and mechanical parameters for direct substitution. Selection should be based on product status and availability:

ERJ-S1DF26R1U remains the primary choice for new designs, maintaining Active status with full manufacturer support. This part includes anti-sulfur coating as an additional feature.

ERJ-12SF26R1U is marked as Not For New Designs and should be used only for legacy system maintenance or repair applications where existing inventory must be maintained.

CRCW201026R1FKEF from Vishay Dale is an Active alternative from a different manufacturer, offering equivalent electrical performance and automotive qualification. This part provides an additional sourcing option with higher current inventory availability.

All three parts carry ROHS3 compliance and AEC-Q200 automotive qualification, ensuring suitability for regulated applications.

Frequently Asked Questions (FAQ)

Q: Can ERJ-12SF26R1U be used in new product designs? A: No. ERJ-12SF26R1U carries a Not For New Designs status and should be reserved for legacy system support only. Use ERJ-S1DF26R1U or CRCW201026R1FKEF for new designs.

Q: Are all substitute parts physically identical? A: Yes. All parts share the same 2010 (5025 Metric) package dimensions: 0.197" L x 0.098" W (5.00mm x 2.50mm) with maximum seated height of 0.028" (0.70mm). They are mechanically interchangeable on PCBs designed for this footprint.

Q: What is the difference between ERJ-S1DF26R1U and ERJ-12SF26R1U? A: Both are Panasonic products with identical electrical specifications. The primary difference is product lifecycle status: ERJ-S1DF26R1U is Active, while ERJ-12SF26R1U is Not For New Designs. ERJ-S1DF26R1U includes anti-sulfur coating.

Q: Do all parts meet automotive standards? A: Yes. All three parts carry AEC-Q200 automotive qualification and ROHS3 compliance, meeting automotive industry requirements for reliability and environmental standards.

Q: Can CRCW201026R1FKEF replace ERJ-S1DF26R1U in existing assemblies? A: Yes. CRCW201026R1FKEF meets all electrical and mechanical specifications. However, verify that your design documentation and qualification records permit cross-manufacturer substitution before implementation.

Q: What is the moisture sensitivity rating, and why does it matter? A: All parts carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. These components can be stored and handled without special moisture control measures, simplifying supply chain management.
