Substitute Part Grouping Explanation

Substitution of the LTR50UZPJ6R8 is permissible with parts that maintain the following critical parameters:

• Resistance value: 6.8 Ohms (exact match required)
• Power rating: 1W (minimum requirement)
• Package: Wide 2010 (5025 Metric), 1020 (mechanical and thermal compatibility)
• Composition: Thick Film (electrical performance characteristics)
• Operating temperature range: -55°C to 155°C (minimum coverage required)
• Automotive qualification: AEC-Q200 (mandatory for automotive applications)
• RoHS compliance: ROHS3 Compliant (regulatory requirement)

Tolerance and temperature coefficient may vary within acceptable engineering limits provided all other parameters remain equivalent. The LTR50UZPF6R80 meets all substitution criteria with an enhanced tolerance specification (±1% versus ±5%) and improved temperature coefficient (±100ppm/°C versus ±200ppm/°C).

Parameter Comparison

Engineering Selection Recommendations

The LTR50UZPF6R80 is a direct substitute for the LTR50UZPJ6R8 based on identical resistance value, power rating, package dimensions, and automotive AEC-Q200 qualification. Both parts are manufactured by Rohm Semiconductor and maintain ROHS3 compliance and MSL 1 rating.

The LTR50UZPF6R80 provides enhanced performance characteristics with tighter tolerance (±1% versus ±5%) and lower temperature coefficient (±100ppm/°C versus ±200ppm/°C). These improvements result in superior stability across the full operating temperature range and reduced resistance drift in precision circuit applications.

Selection between these parts depends on circuit requirements for tolerance and temperature stability. Both parts are active in production with established supply availability.

Frequently Asked Questions (FAQ)

Q: Can the LTR50UZPF6R80 replace the LTR50UZPJ6R8 in existing designs?
