Substitute Part Grouping Explanation

Substitution of the LTR50UZPJ270 is determined by strict equivalence in the following critical parameters:

• Resistance value: 27 Ohms (exact match required)
• Power rating: 1W (exact match required)
• Package format: Wide 2010 (5025 Metric), 1020 (exact match required)
• Composition: Thick Film (exact match required)
• Automotive qualification: AEC-Q200 (maintained)
• Operating temperature range: -55°C ~ 155°C (maintained or exceeded)
• RoHS compliance: ROHS3 (maintained)

The identified substitute part LTR50UZPF27R0 maintains all critical mechanical and electrical parameters while offering improved tolerance specification (±1% versus ±5%) and lower temperature coefficient (±100ppm/°C versus ±200ppm/°C). Both parts are manufactured by Rohm Semiconductor within the same LTR series and share identical package dimensions and automotive certifications.
