Engineering Selection Recommendations

Selection of substitute diodes for 1PS193,115 is based on matching electrical parameters, package compatibility, and compliance certifications. All listed substitutes are ROHS3 compliant, carry MSL 1 (Unlimited) ratings, and are REACH unaffected. Product status should be reviewed; 1PS193,115 is obsolete, whereas BAS16,215 is active. Substitute parts also conform to the same diode rectifier category and provide at least the required reverse voltage, forward current, and corresponding packaging.

Frequently Asked Questions (FAQ)

Q1: What are the absolute required parameters for substituting the 1PS193,115?
A1: Substitution requires matching or exceeding the voltage rating (Vr), current rating (Io), forward voltage (Vf), reverse recovery time (trr), reverse leakage current, capacitance, and ensuring identical mounting type and package compatibility.

Q2: Are all listed substitutes compatible with the TO-236-3, SC-59, SOT-23-3 footprint?
A2: All listed substitutes specify compatibility with the TO-236-3, SC-59, or SOT-23-3 packages, ensuring appropriate fit for standard surface mount layouts.

Q3: Does ROHS and MSL compliance vary between alternatives?
A3: All substitutes and the original part are ROHS3 compliant and have Moisture Sensitivity Level (MSL) 1 (Unlimited). All parts indicate REACH Unaffected status.

Q4: Is the reverse recovery speed and leakage current equivalent in all suggested alternatives?
A4: All substitutes, except BAS116-7-F, indicate fast recovery characteristics and comparable leakage. BAS116-7-F has a longer reverse recovery time.

Q5: Are there any differences in rated current or voltage among substitutes?
A5: Substitute parts match or exceed the 215 mA current and 80 V reverse voltage specified for 1PS193,115.

Q6: How important is the supplier device package in selecting a substitute?
A6: The supplier device package is important for mechanical fit and automated assembly. All listed substitutes provide compatible surface mount options.
