Key Parameters

Substitute Part Grouping Explanation

Substitution of the LTR50UZPJ331 is determined by maintaining electrical and mechanical compatibility across the following critical parameters:

Resistance value must remain 330 Ohms. Package configuration must be Wide 2010 (5025 Metric), 1020 to ensure PCB footprint compatibility. Power rating must be maintained at 1W minimum. Automotive AEC-Q200 qualification must be retained. Operating temperature range must span -55°C to 155°C. Composition must be thick film. RoHS3 compliance must be maintained.

The LTR50UZPJ331 can be substituted with parts that meet or exceed these baseline requirements. Tolerance specifications may be tightened from ±5% to ±1% without affecting mechanical or thermal compatibility, provided all other parameters remain equivalent.

Parameter Comparison

Engineering Selection Recommendations

The LTR50UZPJ331 and LTR50UZPF3300 are both active production parts from Rohm Semiconductor with identical mechanical compatibility and automotive qualification. Both components maintain ROHS3 compliance and AEC-Q200 certification, ensuring suitability for automotive applications.

The primary distinction between these parts is tolerance specification. The LTR50UZPF3300 provides ±1% tolerance compared to the ±5% tolerance of the LTR50UZPJ331, with a corresponding improvement in temperature coefficient from ±200ppm/°C to ±100ppm/°C. This substitution is appropriate when circuit designs require tighter resistance accuracy or improved thermal stability while maintaining identical package footprint and power handling characteristics.

Both parts are suitable for direct substitution on existing PCB layouts without modification to land patterns or assembly procedures.

Frequently Asked Questions (FAQ)

Q: Can the LTR50UZPF3300 replace the LTR50UZPJ331 in existing designs?

A: Yes. Both parts share identical package dimensions (Wide 2010, 5025 Metric), resistance value (330 Ohms), power rating (1W), and operating temperature range (-55°C to 155°C). PCB footprints and assembly processes require no modification.

Q: What is the primary advantage of the LTR50UZPF3300 over the LTR50UZPJ331?

A: The LTR50UZPF3300 provides tighter tolerance (±1% versus ±5%) and improved temperature coefficient (±100ppm/°C versus ±200ppm/°C), resulting in enhanced resistance accuracy and thermal stability across the operating temperature range.
