Engineering Selection Recommendations

The S1J-E3/61T is the appropriate selection for applications currently specified with the CS1J-E3/H. The substitute part is manufactured by the same supplier and maintains all critical electrical parameters within the specified operating range. The S1J-E3/61T carries active product status, ensuring long-term availability and supply chain continuity.

The S1J-E3/61T is RoHS3 Compliant and REACH Unaffected, meeting current regulatory requirements. The part is available in Cut Tape (CT) and Digi-Reel® packaging formats with substantial inventory levels, supporting both prototype and production-volume requirements.

Minor parameter variations exist within acceptable engineering tolerances: forward voltage is 0.02 V lower, reverse recovery time is 0.3 µs longer, reverse leakage current is lower, and junction capacitance is higher. These variations remain within standard rectifier diode performance specifications and do not affect functional compatibility in standard rectification applications.

Frequently Asked Questions (FAQ)

Q: Can the S1J-E3/61T be used as a direct replacement for the CS1J-E3/H in existing designs?

A: Yes. Both parts share identical voltage ratings (600 V), current ratings (1 A), package type (DO-214AC, SMA), and mounting configuration (surface mount). The electrical parameters fall within compatible ranges for rectification applications.

Q: What is the primary reason for substitution?

A: The CS1J-E3/H is classified as obsolete. The S1J-E3/61T is an active product from the same manufacturer with equivalent specifications and superior availability.

Q: Are there differences in forward voltage between these parts?

A: The S1J-E3/61T exhibits a forward voltage of 1.1 V at 1 A compared to 1.12 V for the CS1J-E3/H. This 0.02 V difference is within standard rectifier diode tolerances and does not affect circuit performance in typical applications.

Q: How do the reverse recovery times compare?

A: The CS1J-E3/H specifies 1.5 µs reverse recovery time, while the S1J-E3/61T specifies 1.8 µs. Both fall within the standard recovery classification (>500 ns, >200 mA). This difference is negligible for general-purpose rectification applications.

Q: What packaging options are available for the S1J-E3/61T?

A: The S1J-E3/61T is supplied in Cut Tape (CT) and Digi-Reel® formats, supporting both prototype and production procurement methods.

Q: Does the S1J-E3/61T meet current regulatory standards?

A: Yes. The S1J-E3/61T is RoHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory requirements.

Q: Are there any differences in reverse leakage current?

A: The S1J-E3/61T exhibits lower reverse leakage current (1 µA @ 600 V) compared to the CS1J-E3/H (5 µA @ 600 V). Lower leakage current represents improved performance characteristics and does not affect compatibility.

Q: What is the moisture sensitivity level of the S1J-E3/61T?

A: The S1J-E3/61T carries Moisture Sensitivity Level (MSL) 1, indicating unlimited shelf life without moisture control requirements.
