A: Yes. The SS310L RUG is available in Tape & Reel (TR) packaging, matching the original SS310L packaging format. All electrical and mechanical specifications are identical.

Q: Do all substitute parts meet the same environmental and compliance standards?

A: Yes. All substitute parts are ROHS3 Compliant, REACH Unaffected, and carry Moisture Sensitivity Level 1 (Unlimited). Operating temperature range is -55°C to 150°C for all variants.

Q: What electrical parameters must remain constant when selecting a substitute?

A: The following parameters must match exactly: Voltage - DC Reverse (100 V), Current - Average Rectified (3 A), Voltage - Forward (850 mV @ 3 A), Speed (Fast Recovery ≤ 500 ns, > 200 mA), and Current - Reverse Leakage (100 µA @ 100 V).

Q: Are there any performance differences between the various SS310L substitute variants?

A: No. All variants (M2G, MHG, MQG, MTG, R3G, RFG, RHG, RQG, RTG, RUG) maintain identical electrical performance specifications. Variant designations reflect manufacturing process or date code differences without affecting functional characteristics.

Q: Which substitute part should I select for new design implementations?

A: Any of the listed substitute parts with "Active" product status are suitable for new designs. Selection should be based on packaging requirements (Tape & Reel versus standard) and current inventory availability. All variants provide equivalent performance and compliance.
