Key Parameters

Substitute Part Grouping Explanation

Substitute relationships for the 2SA1576UBTLR are determined strictly by the alignment of essential electrical and mechanical parameters, including transistor type, collector-emitter breakdown voltage, collector current rating, saturation voltage, collector cutoff current, DC current gain, maximum power dissipation, transition frequency, operating temperature, mounting type, package/case, compliance standards, and supply chain classification. Only parts matching or exceeding specified levels within these fields are considered suitable equivalents.

Parameter Comparison

Engineering Selection Recommendations

Selection of substitute parts should prioritize components with "Active" product status and confirmed ROHS3 and REACH compliance. Both the 2SA1576UBTLR and 2SAR523UBTL meet these compliance conditions, but only 2SAR523UBTL is listed as "Active." Inventory availability and environmental compliance classifications (MSL 1, ROHS3, REACH Unaffected) are directly referenced for suitability. Product status "Not For New Designs" prompts replacement with an "Active" alternative for ongoing and future applications.

Frequently Asked Questions (FAQ)

Q1: What are the critical parameters for selecting substitutes for 2SA1576UBTLR?
A1: Substitute selection is based on transistor type, collector-emitter breakdown voltage, maximum collector current, saturation voltage, collector cutoff current, DC current gain, maximum power rating, transition frequency, operating temperature, package, mounting type, RoHS and REACH compliance, and moisture sensitivity level.

Q2: Is the package type of substitute parts identical to 2SA1576UBTLR?
A2: Both 2SA1576UBTLR and 2SAR523UBTL use the SC-85 case and UMT3F supplier device package, ensuring mechanical compatibility.

Q3: Does the substitute part comply with environmental and supply chain standards?
A3: Yes, both parts are listed as ROHS3 compliant, REACH unaffected, and have MSL 1 classification.

Q4: Should new designs continue to use 2SA1576UBTLR?
A4: The product status "Not For New Designs" indicates that substitutes such as 2SAR523UBTL (Active status) should be used for new projects.

Q5: How does transition frequency affect part substitution?
A5: Transition frequency is a comparison metric; 2SA1576UBTLR is specified at 140MHz and 2SAR523UBTL at 300MHz, both values are referenced for compatibility assessment within allowed design criteria.
