Engineering Selection Recommendations

S1MSP1M-7 is the direct substitute with active product status. This part carries automotive-grade qualification (AEC-Q101) and is supplied in Tape & Reel packaging. The S1MSP1M-7 is suitable for applications requiring automotive-level reliability and traceability. Moisture Sensitivity Level (MSL) is rated 1 (Unlimited), indicating no moisture sensitivity constraints.

S1MSP1N-7 is the manufacturer-recommended substitute with active product status. This part maintains identical electrical specifications and package configuration to the original S1MSP1-7. The S1MSP1N-7 provides direct functional equivalence for general-purpose rectification applications.

Both substitute parts are manufactured by Diodes Incorporated and are ROHS3 compliant. Selection between S1MSP1M-7 and S1MSP1N-7 depends on application requirements for automotive qualification and packaging format.

Frequently Asked Questions (FAQ)

Q: Can S1MSP1M-7 and S1MSP1N-7 be used interchangeably with S1MSP1-7?

A: Both S1MSP1M-7 and S1MSP1N-7 are electrical and mechanical equivalents to S1MSP1-7. They share identical voltage ratings (1000 V), current ratings (1 A), forward voltage characteristics (1.1 V @ 1 A), reverse recovery time (1.2 µs), and package configuration (POWERDI®123). Direct substitution is supported for applications within these specifications.

Q: What is the difference between S1MSP1M-7 and S1MSP1N-7?

A: S1MSP1M-7 carries automotive-grade qualification (AEC-Q101) and is supplied in Tape & Reel packaging with MSL 1 rating. S1MSP1N-7 is the manufacturer-recommended substitute without automotive qualification. Both parts are electrically identical and use the same POWERDI®123 package.

Q: Why is S1MSP1-7 listed as obsolete?

A: S1MSP1-7 has reached end-of-life status. S1MSP1M-7 and S1MSP1N-7 are active alternatives that provide equivalent electrical performance and package compatibility for continued design support.

Q: Are there packaging differences between these parts?

A: S1MSP1-7 and S1MSP1N-7 do not specify packaging format. S1MSP1M-7 is supplied in Tape & Reel (TR) format. All three parts use the POWERDI®123 surface mount package.

Q: Do these parts meet RoHS compliance requirements?

A: All three parts (S1MSP1-7, S1MSP1M-7, and S1MSP1N-7) are ROHS3 compliant. S1MSP1M-7 is REACH Unaffected, while S1MSP1-7 and S1MSP1N-7 are REACH Unaffected.

Q: What is the operating temperature range for these diodes?

A: All three parts operate across a junction temperature range of -55°C to 150°C, supporting both industrial and automotive temperature environments.
