Key Parameters

Substitute Part Grouping Explanation

Substitution of the LTR50UZPJ101 is determined by the following critical parameters:

• Resistance value: 100 Ohms (exact match required)
• Power rating: 1W (exact match required)
• Package/Case: Wide 2010 (5025 Metric), 1020 (exact match required for PCB compatibility)
• Composition: Thick Film (maintained across all substitutes)
• Automotive compliance: AEC-Q200 (maintained for automotive applications)
• Operating temperature range: -55°C ~ 155°C (maintained)
• RoHS compliance: ROHS3 Compliant (maintained)

The LTR50UZPF1000 qualifies as a direct substitute based on these parameters. The primary difference is tolerance specification (±1% versus ±5%), which represents an upgrade in precision without affecting mechanical or thermal compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the LTR50UZPJ101 and LTR50UZPF1000 maintain identical mechanical compatibility and thermal performance within the specified operating range. Both parts are active products from Rohm Semiconductor with full AEC-Q200 automotive qualification and ROHS3 compliance.

The LTR50UZPF1000 offers improved tolerance specification (±1% versus ±5%) and lower temperature coefficient (±100ppm/°C versus ±200ppm/°C), making it suitable for applications requiring tighter resistance accuracy. The LTR50UZPJ101 remains appropriate for applications where ±5% tolerance meets circuit requirements.

Selection between these parts should be based on circuit tolerance requirements and application specifications. Both parts are suitable for direct substitution in Wide 2010 package footprints without PCB redesign.

Frequently Asked Questions (FAQ)

Q: Can LTR50UZPF1000 be used as a direct replacement for LTR50UZPJ101?

A: Yes. Both parts share identical package dimensions, power rating, resistance value, operating temperature range, and automotive compliance. The LTR50UZPF1000 provides tighter tolerance and lower temperature coefficient specifications.

Q: Are there any PCB layout considerations when substituting these parts?

A: No. Both parts use the identical Wide 2010 (5025 Metric) package with matching footprint dimensions (0.098" L x 0.197" W, 2.50mm x 5.00mm) and height (0.026" maximum). No PCB modifications are required.

Q: What is the difference in tolerance between these parts?

A: The LTR50UZPJ101 has ±5% tolerance, while the LTR50UZPF1000 has ±1% tolerance. The LTR50UZPF1000 provides tighter resistance accuracy for precision-critical applications.

Q: Do both parts meet automotive qualification requirements?

A: Yes. Both the LTR50UZPJ101 and LTR50UZPF1000 are rated to AEC-Q200 automotive standards and are ROHS3 compliant.

Q: What is the temperature coefficient difference?

A: The LTR50UZPJ101 has a temperature coefficient of ±200ppm/°C, while the LTR50UZPF1000 has ±100ppm/°C. The lower coefficient in the LTR50UZPF1000 provides better resistance stability across the -55°C to 155°C operating range.
