Substitute Part Grouping Explanation

Substitution eligibility for the LTR50UZPJ332 is determined by the following criteria:

• Identical resistance value: 3.3 kOhms
• Identical power rating: 1W
• Identical package: Wide 2010 (5025 Metric), 1020
• Identical physical dimensions: 0.098" L x 0.197" W (2.50mm x 5.00mm), height 0.026" (0.65mm) maximum
• Identical composition: Thick Film
• Identical operating temperature range: -55°C ~ 155°C
• Identical automotive qualification: AEC-Q200
• Identical RoHS compliance: ROHS3 Compliant
• Identical moisture sensitivity level: MSL 1 (Unlimited)

The LTR50UZPF3301 qualifies as a direct substitute based on these parameters. The tolerance specification may differ (±1% versus ±5%) without affecting mechanical or thermal compatibility, as tolerance represents a tighter specification of the same nominal value.

Parameter Comparison

Engineering Selection Recommendations

Both the LTR50UZPJ332 and LTR50UZPF3301 are active production components from Rohm Semiconductor with identical AEC-Q200 automotive qualification and ROHS3 compliance. Selection between these parts depends on application tolerance requirements. The LTR50UZPJ332 with ±5% tolerance is suitable for general automotive applications where standard tolerance specifications are acceptable. The LTR50UZPF3301 with ±1% tolerance provides enhanced precision and lower temperature coefficient (±100ppm/°C versus ±200ppm/°C), making it appropriate for circuits requiring tighter resistance accuracy and improved thermal stability. Both components share identical mechanical compatibility, thermal operating range, and regulatory compliance status.

Frequently Asked Questions (FAQ)

Q: Can LTR50UZPF3301 be used as a direct replacement for LTR50UZPJ332?

A: Yes. Both parts share identical resistance value, power rating, package dimensions, composition, operating temperature range, and automotive qualification. The LTR50UZPF3301 features tighter tolerance (±1% versus ±5%) and lower temperature coefficient, making it functionally compatible and electrically superior for precision applications.

Q: Are there any physical compatibility concerns when substituting these parts?

A: No. Both components use the identical Wide 2010 (5025 Metric) package with matching dimensions of 0.098" L x 0.197" W and maximum seated height of 0.026". PCB footprints and assembly processes remain unchanged.

Q: Do both parts meet automotive standards?

A: Yes. Both LTR50UZPJ332 and LTR50UZPF3301 carry AEC-Q200 qualification and ROHS3 compliance, meeting automotive industry requirements for reliability and environmental standards.

Q: What is the difference in temperature coefficient between these parts?

A: The LTR50UZPJ332 has a temperature coefficient of ±200ppm/°C, while the LTR50UZPF3301 has ±100ppm/°C. The lower coefficient in the substitute part indicates better resistance stability across the -55°C to 155°C operating range.

Q: Are moisture sensitivity levels identical?

A: Yes. Both parts are rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.
