SD840CS_S2_00001 Equivalent & Substitute Parts

Part Overview

The SD840CS_S2_00001 is a Schottky diode array manufactured by Panjit International Inc., configured as 1 pair common cathode with a maximum reverse voltage of 40 V and average rectified current of 8 A per diode. The device is packaged in TO-252-3 (DPAK) surface mount configuration and is classified as Active product status.

Substitute parts are identified when equivalent electrical and mechanical parameters are maintained across the same diode configuration, voltage rating, current capacity, and package type. The primary substitute differs in packaging format (Cut Tape versus Tape & Reel) and product status classification.

Substitute Part Grouping Explanation

Substitution eligibility for the SD840CS_S2_00001 is determined by strict equivalence across the following critical parameters:

• Diode Configuration: 1 Pair Common Cathode (electrical topology must match)
• Voltage Rating: 40 V DC reverse maximum (Vr)
• Current Rating: 8 A average rectified current per diode (Io)
• Forward Voltage Characteristics: 550 mV maximum at 4 A (Vf)
• Recovery Speed: Fast Recovery ≤ 500 ns, > 200 mA (Io)
• Reverse Leakage: 200 µA @ 40 V
• Package Type: TO-252-3, DPAK surface mount configuration
• Temperature Range: -55°C ~ 150°C junction operating range
• Compliance: ROHS3 Compliant, REACH Unaffected

The identified substitute maintains all electrical and mechanical parameters within these specifications. Differences in packaging format (Tape & Reel versus Cut Tape) and product status do not affect functional equivalence in circuit applications.

Engineering Selection Recommendations

SD840CS_S2_00001 (Primary Selection)

The SD840CS_S2_00001 is the recommended selection for new designs and ongoing production. This part maintains Active product status, ensuring continued manufacturer support and availability. The Tape & Reel packaging format is optimized for high-volume automated assembly processes. ROHS3 compliance and REACH unaffected status satisfy current environmental and regulatory requirements.

SD840CS_L2_00001 (Substitute - Obsolete Status)

The SD840CS_L2_00001 is electrically and mechanically equivalent but carries Obsolete product status classification. This part is suitable only for legacy system maintenance, repair, or replacement applications where the original part number must be preserved. The Cut Tape packaging format is appropriate for manual assembly or low-volume applications. Availability may be limited due to obsolete status; inventory verification is required prior to procurement.

Both parts share identical electrical performance characteristics, thermal operating range, and compliance certifications. Selection between these parts is determined by application context (new design versus legacy support) and packaging requirements (automated versus manual assembly).

Frequently Asked Questions (FAQ)

Q: Can SD840CS_L2_00001 be used as a direct replacement for SD840CS_S2_00001 in new designs?

A: Yes. The SD840CS_L2_00001 is electrically and mechanically equivalent. However, the SD840CS_S2_00001 is recommended for new designs due to Active product status and superior availability. The substitute is appropriate for legacy applications or when Cut Tape packaging is specifically required.

Q: What is the difference between Tape & Reel and Cut Tape packaging?

A: Tape & Reel (TR) packaging supplies components on continuous carrier tape wound on reels, optimized for automated pick-and-place assembly. Cut Tape (CT) packaging supplies the same components on cut segments of carrier tape, suitable for manual assembly or lower-volume applications. Both formats contain identical components in the same TO-252-3 package.

Q: Are the electrical specifications identical between these two parts?

A: Yes. Both parts share identical specifications for voltage rating (40 V), current capacity (8 A), forward voltage (550 mV @ 4 A), reverse leakage (200 µA @ 40 V), recovery speed (≤ 500 ns), and operating temperature range (-55°C ~ 150°C).

Q: Why is SD840CS_L2_00001 marked as Obsolete?

A: Obsolete status indicates the manufacturer has discontinued active production and support for this part number. The substitute SD840CS_S2_00001 represents the current active equivalent. Existing inventory of the obsolete part may still be available from distributors.

Q: Can these parts be used interchangeably on the same PCB assembly?

A: Yes. Both parts use identical TO-252-3 DPAK surface mount packages with the same pinout and footprint. They are mechanically and electrically interchangeable at the circuit level. Packaging format differences (Tape & Reel versus Cut Tape) affect only the supply and handling method, not the component itself.

Q: What compliance certifications apply to both parts?

A: Both parts are ROHS3 Compliant and REACH Unaffected. These certifications confirm compliance with European environmental and hazardous substance restrictions.

Q: Is there a moisture sensitivity concern with these components?

A: No. Both parts carry Moisture Sensitivity Level (MSL) 1, which indicates Unlimited shelf life without moisture control requirements. Standard storage conditions are sufficient.
