Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-B2CJR10V is determined by the following critical parameters:

• Resistance value: 100 mOhms (exact match required)
• Power rating: 1W (exact match required)
• Package configuration: Wide 1206 (3216 metric), 0612 (exact match required)
• Physical dimensions: 0.063" L x 0.126" W, height 0.031" max (exact match required)
• Composition: Thick film (exact match required)
• Operating temperature range: -55°C to 155°C (exact match or better required)
• Automotive compliance: AEC-Q200 (exact match required)
• RoHS compliance: ROHS3 (exact match required)

The ERJ-B2CFR10V qualifies as a direct substitute because it maintains all critical electrical and mechanical parameters while offering improved tolerance specification (±1% versus ±5%) and superior temperature coefficient performance (0/+150ppm/°C versus 0/+200ppm/°C).

Parameter Comparison

Engineering Selection Recommendations

Both the ERJ-B2CJR10V and ERJ-B2CFR10V are active production components with full AEC-Q200 automotive qualification and ROHS3 compliance. The ERJ-B2CFR10V offers superior tolerance performance (±1% versus ±5%) and lower temperature coefficient drift (0/+150ppm/°C versus 0/+200ppm/°C), making it suitable for applications requiring tighter resistance accuracy. Both parts maintain identical mechanical compatibility and thermal operating range. Selection between these parts depends on application-specific tolerance requirements and inventory availability constraints.

Frequently Asked Questions (FAQ)
