Substitute Part Grouping Explanation

Substitutes for the FS1ME_HF diode are grouped based on strict parametric equivalence. Only diodes that match or exceed the following parameters are considered: voltage (Vr), current rating (Io), forward voltage (Vf) at the rated current, reverse recovery time (trr), reverse leakage current, capacitance, mounting type, package or case, operating temperature range, RoHS and REACH compliance, and active product status. Mechanical compatibility and identical package references (DO-219AA) are required.

Parameter Comparison

Engineering Selection Recommendations

Both FS1ME_HF and FS1MED-7 are active and share ROHS3 compliant and REACH unaffected status, indicating alignment with environmental standards. Product status and compliance data confirm suitability for direct substitution in applications requiring regulatory conformity and continued availability under ECCN EAR99 and HTSUS 8541.10.0080.

Frequently Asked Questions (FAQ)

Q1: What parameters must match for substituting FS1ME_HF with FS1MED-7?
A1: Substitute parts must match the voltage rating (1000 V), current rating (1A), forward voltage (1.1 V @ 1A), reverse leakage current (5 µA @ 1000 V), capacitance, package (DO-219AA), mounting type (surface mount), operating temperature range, and compliance status.

Q2: Is the reverse recovery time a critical consideration for compatibility?
A2: Reverse recovery time is provided for both parts and should be evaluated based on specific design requirements. Both values fall within the standard recovery range for this product category.

Q3: Are there package or mounting differences between FS1ME_HF and FS1MED-7?
A3: Both diodes use the DO-219AA surface mount package, ensuring mechanical interchangeability.

Q4: Does the compliance status affect substitution eligibility?
A4: Both models are ROHS3 compliant and REACH unaffected, meeting standard environmental and safety regulations for electronic components.

Q5: Are there inventory or sourcing advantages to using the substitute part?
A5: Both FS1ME_HF and FS1MED-7 are listed as active status with available inventory, supporting supply chain flexibility provided key parameters are matched.
