Engineering Selection Recommendations

Selections should be based on product status (Active vs. Not For New Designs), RoHS compliance (ROHS3 Compliant), moisture sensitivity level (MSL 1, Unlimited), and inventory availability. All substitutes and parametric equivalents listed above match the electrical and mechanical parameters provided. The following are suitable for direct substitution as engineering equivalents for 2SC4617EBTLR:

2SC4617EBTLS
2SC4617EBHZGTLQ
2SC4617EBHZGTLR
2SC4617EBTLQ
2SCR523EBTL

Parts with "Active" product status may be prioritized for new designs or ongoing procurement, while those designated "Not For New Designs" remain suitable for maintenance or legacy designs per project requirements.

Frequently Asked Questions (FAQ)

Q1: What parameters must match when substituting a Bipolar (BJT) NPN transistor like 2SC4617EBTLR?
A1: Substitute parts must match NPN polarity, collector-emitter breakdown voltage, maximum collector current, saturation voltage, cutoff current, minimum DC current gain, power dissipation, transition frequency, operating temperature, mounting type, and package/case type.

Q2: Why must the package and mounting type be identical for substitution?
A2: For direct board-level replacement and assembly compatibility, the substitute must match the SC-89, SOT-490 package and EMT3F (SOT-416FL) supplier device package in surface mount format.

Q3: Is RoHS or MSL relevant for substitution selection?
A3: Yes. All listed substitutes comply with ROHS3 and have an MSL of 1 (Unlimited), ensuring suitability for compliant, high-volume assembly requirements.

Q4: Can 2SCR523EBTL be used as a substitute for 2SC4617EBTLR?
A4: 2SCR523EBTL matches the required electrical and mechanical specifications, with a lower maximum collector current (100mA). It shares the same package and compliance features and is designated as "Active" status.

Q5: How do I prioritize among listed substitutes?
A5: Prioritize substitutes with "Active" product status if long-term supply is required. Ensure part number and package compatibility for direct replacement on existing designs.

Q6: Are the automotive-series devices compatible for substitution in general applications?
A6: Devices marked as Automotive, AEC-Q101 (e.g., 2SC4617EBHZGTLQ, 2SC4617EBHZGTLR) retain identical parameters and package compatibility; they can be used wherever the original part’s specifications are required.
