Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LTR50UZPJ471 is determined by the following criteria:

Critical Parameters (Must Match):

• Resistance value: 470 Ohms
• Power rating: 1W
• Package type: Wide 2010 (5025 Metric), 1020
• Physical dimensions: 0.098" L x 0.197" W (2.50mm x 5.00mm)
• Operating temperature range: -55°C ~ 155°C
• Automotive qualification: AEC-Q200
• Composition: Thick Film

Allowable Variation Parameters:

• Tolerance: Can be improved from ±5% to ±1% (tighter tolerance is acceptable)
• Temperature coefficient: Can be improved from ±200ppm/°C to ±100ppm/°C (lower coefficient is acceptable)

The LTR50UZPF4700 qualifies as a direct substitute because it maintains all critical parameters while offering improved tolerance and temperature coefficient specifications.

Parameter Comparison

Engineering Selection Recommendations

The LTR50UZPF4700 is a qualified substitute for the LTR50UZPJ471 based on the following engineering criteria:

Both parts are manufactured by Rohm Semiconductor and maintain identical mechanical compatibility with the Wide 2010 package footprint. Both components carry AEC-Q200 automotive qualification and ROHS3 compliance, ensuring regulatory and quality standards are met in automotive applications.

The LTR50UZPF4700 provides improved tolerance specification (±1% versus ±5%) and superior temperature coefficient performance (±100ppm/°C versus ±200ppm/°C). These enhancements do not introduce any incompatibility with the original design and are suitable for applications where tighter tolerance control is beneficial.

Selection between these parts should be based on circuit tolerance requirements and inventory availability. The LTR50UZPF4700 offers higher stock availability (1489 units versus 756 units).
