Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LTR18EZPJ2R2 is determined by the following critical parameters:

• Resistance value must remain 2.2 Ohms
• Power rating must be 1.5W or greater
• Package / Case must be Wide 1206 (3216 Metric), 0612
• Operating temperature range must cover -55°C ~ 155°C
• Automotive AEC-Q200 qualification must be maintained
• Composition must be Thick Film
• RoHS3 compliance must be present

The LTR18EZPF2R20 meets all substitution criteria. This part maintains identical resistance, power rating, package dimensions, and automotive qualification while offering improved tolerance (±1% versus ±5%) and superior temperature coefficient (±100ppm/°C versus ±200ppm/°C).

Parameter Comparison

Engineering Selection Recommendations

Both the LTR18EZPJ2R2 and LTR18EZPF2R20 are active production parts from Rohm Semiconductor with full AEC-Q200 automotive qualification and ROHS3 compliance. The parts are mechanically and electrically interchangeable within the specified operating temperature range of -55°C to 155°C.

The LTR18EZPF2R20 provides enhanced performance characteristics through tighter tolerance specification (±1% versus ±5%) and improved temperature stability (±100ppm/°C versus ±200ppm/°C). Selection between these parts depends on circuit requirements for tolerance and temperature coefficient performance. Both parts maintain identical power dissipation capability, package footprint, and automotive qualification status.
