• Tolerance: ±1% (exact match required)
• Power Rating: 0.1W / 1/10W (exact match required)
• Package Dimensions: 0603 (1608 Metric) with identical physical footprint (0.063" L x 0.031" W, 1.60mm x 0.80mm)
• Composition: Thick Film (exact match required)
• Temperature Coefficient: -100 / +600 ppm/°C (exact match required)
• Operating Temperature Range: -55°C ~ 155°C (exact match required)
• Automotive Qualification: AEC-Q200 (exact match required)
• Environmental Compliance: ROHS3 Compliant, REACH Unaffected (exact match required)

Substitutes within this grouping are interchangeable at the circuit level and PCB assembly level without design modification or performance degradation.

Parameter Comparison

Engineering Selection Recommendations

The ERJ-U03F9R10V is a direct functional equivalent to the ERJ-S03F9R10V. Both parts are manufactured by Panasonic Electronic Components and share identical electrical specifications, mechanical dimensions, and compliance certifications. The primary distinction between these parts is the series designation (ERJ-S03 versus ERJ-U03) and packaging format. The ERJ-S03F9R10V is supplied in standard packaging, while the ERJ-U03F9R10V is supplied in Tape & Reel (TR) format.

Both parts maintain active production status and are ROHS3 compliant with REACH Unaffected designation. Both carry AEC-Q200 automotive qualification and anti-sulfur coating for reliability in harsh environments. The identical operating temperature range (-55°C ~ 155°C), temperature coefficient (-100 / +600 ppm/°C), and moisture sensitivity level (MSL 1 - Unlimited) ensure equivalent performance in automotive and industrial applications.

Selection between these parts should be based on packaging requirements and supply chain availability. The ERJ-U03F9R10V offers higher inventory availability (6097 pieces in stock) compared to the ERJ-S03F9R10V (941 pieces in stock).
