Substitute Part Grouping Explanation

Substitute parts for the S1KL MHG are identified through parametric equivalence matching. The substitution logic is based on the following critical parameters that must remain constant across all equivalent devices:

Voltage - DC Reverse (Vr) (Max): 800 V
Current - Average Rectified (Io): 1 A
Voltage - Forward (Vf) (Max) @ If: 1.1 V @ 1 A
Reverse Recovery Time (trr): 1.8 µs
Current - Reverse Leakage @ Vr: 5 µA @ 800 V
Capacitance @ Vr, F: 9 pF @ 4 V, 1 MHz
Package / Case: DO-219AB
Mounting Type: Surface Mount
Operating Temperature - Junction: -55°C ~ 175°C

All substitute parts must maintain identical electrical performance characteristics and mechanical compatibility to ensure direct interchangeability in circuit designs.

Engineering Selection Recommendations

The S1KL substitute part is a direct parametric equivalent to the S1KL MHG. Both components are manufactured by Taiwan Semiconductor Corporation and maintain identical electrical and mechanical specifications. Both parts carry Active product status, indicating ongoing manufacturing support and availability.

Regulatory compliance is equivalent across both parts: both are ROHS3 Compliant and REACH Unaffected, meeting current environmental and hazardous substance restrictions. Moisture sensitivity classification is identical at MSL 1 (Unlimited), indicating no special moisture control requirements during storage or handling.

The primary distinction between the two parts is packaging format: the S1KL MHG is supplied in standard packaging, while the S1KL is supplied in Cut Tape (CT) format. This difference affects procurement and assembly logistics but does not impact electrical performance or functional compatibility.

Selection between these parts should be based on packaging and inventory requirements rather than technical performance criteria, as all electrical and thermal characteristics are identical.
