Frequently Asked Questions (FAQ)

Q: Can SS1P6L-M3/85A be used as a direct replacement for SS1P6L-E3/85A?

A: Yes. The SS1P6L-M3/85A is electrically and mechanically equivalent to the SS1P6L-E3/85A. Both parts share identical voltage ratings (60 V), current ratings (1 A), forward voltage characteristics (590 mV @ 1 A), and thermal operating range (-55°C ~ 150°C). The primary difference is product status: SS1P6L-M3/85A is active, while SS1P6L-E3/85A is obsolete.

Q: What is the difference between the /84A and /85A suffix designations?

A: The /84A and /85A suffixes indicate different packaging tape specifications within the same electrical family. Both variants maintain identical electrical performance. Selection between these variants depends on packaging format compatibility with assembly equipment.

Q: Are the automotive-qualified variants (SS1P6LHM3/84A and SS1P6LHM3/85A) suitable for non-automotive applications?

A: Yes. The automotive-qualified variants maintain identical electrical specifications to the standard variants. AEC-Q101 qualification represents an additional quality assurance level and does not restrict use in non-automotive applications. These parts are fully compatible with any circuit design using the standard variants.

Q: What is the significance of the "HM" designation in part numbers SS1P6LHM3/84A and SS1P6LHM3/85A?
