S1KLHMHG Equivalent & Substitute Parts

Part Overview

The S1KLHMHG is a general-purpose rectifier diode manufactured by Taiwan Semiconductor Corporation, rated for 800 V DC reverse voltage and 1 A average rectified current. This surface mount component operates across a junction temperature range of -55°C to 175°C and is qualified to AEC-Q101 automotive standards. The part is actively produced and maintains ROHS3 compliance with unlimited moisture sensitivity rating (MSL 1). Substitute parts are identified to provide alternative sourcing options when the primary part number becomes unavailable or when inventory requirements necessitate alternative procurement channels.

Substitute Part Grouping Explanation

Substitution of the S1KLHMHG with the S1KL is determined by equivalence across all critical electrical and mechanical parameters. Both parts share identical specifications for reverse voltage rating (800 V), average rectified current (1 A), forward voltage drop (1.1 V @ 1 A), reverse recovery time (1.8 µs), reverse leakage current (5 µA @ 800 V), and junction capacitance (9 pF @ 4V, 1MHz). Both components utilize the DO-219AB package with surface mount configuration and operate across the same temperature range (-55°C to 175°C). The substitute part maintains equivalent compliance status: ROHS3 compliance, AEC-Q101 automotive qualification, MSL 1 rating, and REACH unaffected status. The primary distinction between these parts is packaging format: S1KLHMHG is supplied in standard packaging, while S1KL is supplied in cut tape format. This difference affects inventory management and assembly line integration but does not alter electrical or thermal performance characteristics.

Engineering Selection Recommendations

The S1KL serves as a direct parametric equivalent to the S1KLHMHG for applications requiring an 800 V, 1 A general-purpose rectifier diode in DO-219AB surface mount configuration. Both parts maintain active product status and carry identical compliance certifications including AEC-Q101 automotive qualification and ROHS3 compliance. Selection between these parts should be based on packaging and supply chain requirements. The S1KLHMHG is available in standard packaging format with 748 units in current inventory. The S1KL is supplied in cut tape format with significantly higher inventory availability at 30,100 units. For high-volume production environments utilizing automated tape-and-reel assembly processes, the S1KL cut tape format provides operational advantages. For manual assembly or lower-volume applications, the S1KLHMHG standard packaging may be more appropriate. Both parts are manufactured by Taiwan Semiconductor Corporation and share identical electrical performance characteristics, thermal ratings, and regulatory compliance status.

Frequently Asked Questions (FAQ)

Q: Can S1KL be used as a direct replacement for S1KLHMHG in existing circuit designs?

A: Yes. The S1KL is electrically and mechanically equivalent to the S1KLHMHG across all specified parameters. Both components have identical voltage ratings (800 V), current ratings (1 A), forward voltage characteristics (1.1 V @ 1 A), reverse recovery time (1.8 µs), and operating temperature range (-55°C to 175°C). The DO-219AB package footprint is identical for both parts, enabling direct PCB-level substitution.

Q: What is the difference between S1KLHMHG and S1KL packaging?

A: The primary difference is the supply format. S1KLHMHG is supplied in standard packaging, while S1KL is supplied in cut tape (CT) format. Cut tape packaging is designed for automated pick-and-place assembly systems and provides higher unit quantities per reel. Standard packaging is suitable for manual assembly or lower-volume applications. The electrical and thermal performance of the diode itself is identical regardless of packaging format.

Q: Are both parts qualified for automotive applications?

A: Yes. Both S1KLHMHG and S1KL carry AEC-Q101 automotive qualification, indicating compliance with automotive industry reliability and quality standards. Both parts maintain this qualification status and are suitable for automotive circuit applications.

Q: Do both parts have the same compliance certifications?

A: Yes. Both parts are ROHS3 compliant, REACH unaffected, and carry MSL 1 (unlimited moisture sensitivity) rating. Both parts share identical ECCN (EAR99) and HTSUS (8541.10.0080) classifications.

Q: What is the reverse recovery time specification, and is it identical for both parts?

A: The reverse recovery time (trr) is 1.8 µs for both S1KLHMHG and S1KL. This parameter defines the time required for the diode to transition from forward conduction to reverse blocking state and is critical for switching applications. Identical specifications ensure equivalent performance in high-frequency rectification circuits.

Q: Can these parts be used interchangeably in high-temperature applications?

A: Yes. Both parts operate across the identical junction temperature range of -55°C to 175°C. The maximum junction temperature rating of 175°C applies to both S1KLHMHG and S1KL, enabling equivalent performance in thermal environments within this specification.
