Key Parameters

Substitute Part Grouping Explanation

Substitution for the LTR18EZPJ621 is determined by strict equivalence in the following critical parameters: resistance value (620 Ohms), power rating (1.5W), package configuration (Wide 1206/3216 Metric), operating temperature range (-55°C to 155°C), and automotive AEC-Q200 certification. The identified substitute part maintains all these core specifications while offering improved tolerance performance. Tolerance improvement from ±5% to ±1% represents an upgrade path for applications requiring tighter resistance accuracy without any compromise to mechanical fit, thermal performance, or regulatory compliance.

Parameter Comparison

Engineering Selection Recommendations

The LTR18EZPF6200 serves as a direct substitute for the LTR18EZPJ621 with enhanced specifications. Both parts maintain identical mechanical compatibility, thermal performance, and automotive AEC-Q200 certification. The substitute offers improved tolerance accuracy (±1% versus ±5%) and superior temperature coefficient stability (±100ppm/°C versus ±200ppm/°C), making it suitable for applications with stricter resistance value requirements. Both parts are ROHS3 compliant with unlimited moisture sensitivity rating (MSL 1), ensuring equivalent environmental performance. Selection between these parts depends on circuit tolerance requirements; the substitute is appropriate for precision-critical applications while the main part remains suitable for general-purpose automotive applications.

Frequently Asked Questions (FAQ)

Q: Can LTR18EZPF6200 be used as a direct replacement for LTR18EZPJ621?

A: Yes. Both parts share identical resistance value (620 Ohms), power rating (1.5W), package configuration (Wide 1206), operating temperature range (-55°C to 155°C), and AEC-Q200 automotive qualification. The substitute offers improved tolerance and temperature coefficient performance.

Q: What are the mechanical compatibility considerations?

A: Both parts use identical Wide 1206 (3216 Metric) packaging with 0612 supplier device package designation. Physical dimensions, termination count, and maximum seated height are equivalent, ensuring PCB layout and assembly compatibility without modification.

Q: Are there compliance or certification differences?

A: No. Both parts are ROHS3 compliant, REACH unaffected, and carry identical MSL 1 (unlimited) moisture sensitivity ratings. Both maintain AEC-Q200 automotive qualification and pulse withstanding capability.

Q: When should the substitute part be selected over the main part?

A: Select LTR18EZPF6200 when circuit design requires tighter resistance tolerance (±1%) or improved temperature stability (±100ppm/°C). The main part remains appropriate for applications with ±5% tolerance acceptance.

Q: Are there inventory or lead time considerations?

A: LTR18EZPF6200 has higher inventory availability (5578 units versus 1057 units), potentially offering improved procurement lead times for high-volume requirements.
