Substitute Part Grouping Explanation

Substitution of the LTR50UZPJ221 is permissible when the following conditions are met:

The substitute part must maintain identical electrical specifications for resistance value (220 Ohms) and power rating (1W). The substitute must use the same package type (Wide 2010 / 5025 Metric) to ensure mechanical compatibility with existing PCB layouts and assembly processes. The substitute must retain automotive qualification (AEC-Q200) and maintain the same operating temperature range (-55°C ~ 155°C). The substitute must comply with the same environmental standards (ROHS3, REACH Unaffected).

Tolerance can be improved from ±5% to ±1% when circuit design permits tighter component specifications. Temperature coefficient can be improved from ±200ppm/°C to ±100ppm/°C without affecting functional compatibility. These improvements represent upgrades that enhance circuit performance without introducing incompatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the LTR50UZPJ221 and LTR50UZPF2200 are active production parts from Rohm Semiconductor with full AEC-Q200 automotive qualification. Both components comply with ROHS3 and REACH requirements. The LTR50UZPF2200 offers improved tolerance (±1% versus ±5%) and superior temperature coefficient stability (±100ppm/°C versus ±200ppm/°C) while maintaining identical mechanical and thermal specifications. Selection between these parts depends on circuit tolerance requirements and application-specific precision needs. Both parts are suitable for direct substitution in Wide 2010 package footprints.

Frequently Asked Questions (FAQ)

Q: Can LTR50UZPF2200 replace LTR50UZPJ221 in existing designs?

A: Yes. Both parts share identical resistance value (220 Ohms), power rating (1W), package type (Wide 2010), and operating temperature range (-55°C ~ 155°C). The LTR50UZPF2200 provides improved tolerance and temperature coefficient specifications.

Q: What are the key differences between these parts?

A: The primary differences are tolerance specification (±5% versus ±1%) and temperature coefficient (±200ppm/°C versus ±100ppm/°C). All other electrical, mechanical, and environmental specifications are identical.

Q: Are both parts AEC-Q200 qualified?

A: Yes. Both LTR50UZPJ221 and LTR50UZPF2200 carry AEC-Q200 automotive qualification and are suitable for automotive applications.

Q: Do these parts have the same physical dimensions?

A: Yes. Both components use the Wide 2010 (5025 Metric) package with identical dimensions: 0.098" L x 0.197" W (2.50mm x 5.00mm) and maximum seated height of 0.026" (0.65mm).

Q: Which part should be selected for high-precision applications?

A: The LTR50UZPF2200 with ±1% tolerance is appropriate for applications requiring tighter resistance specifications. The LTR50UZPJ221 with ±5% tolerance is suitable for general-purpose applications where wider tolerance is acceptable.

Q: Are both parts RoHS compliant?

A: Yes. Both parts are ROHS3 compliant and REACH unaffected, meeting current environmental regulations.
