Substitute Part Grouping Explanation

The LTR18EZPJLR20 has one identified substitute: LTR18EZPFLR200. Substitution eligibility is determined by the following criteria:

• Identical resistance value: 200 mOhms
• Identical package configuration: Wide 1206 (3216 Metric), 0612
• Identical composition: Thick Film
• Identical temperature coefficient: 0/+150 ppm/°C
• Identical operating temperature range: -55°C to +155°C
• Identical automotive qualification: AEC-Q200
• Identical RoHS and MSL compliance

The substitute part LTR18EZPFLR200 offers improved tolerance (±1% versus ±5%) and increased power rating (1.5W versus 1W), making it suitable for applications requiring tighter resistance accuracy or higher power dissipation within the same footprint and thermal environment.

Parameter Comparison

Engineering Selection Recommendations

Both the LTR18EZPJLR20 and LTR18EZPFLR200 are active production parts with full AEC-Q200 automotive qualification and ROHS3 compliance. Selection between these parts depends on application-specific requirements:

The LTR18EZPJLR20 is appropriate for applications where the ±5% tolerance specification is acceptable and the 1W power rating is sufficient for the circuit design.

The LTR18EZPFLR200 is appropriate for applications requiring tighter resistance tolerance (±1%) or where thermal margin is needed through the increased 1.5W power rating. Both parts occupy identical footprints and operate within the same temperature range, enabling direct substitution at the PCB level.
