Key Parameters

Substitute Part Grouping Explanation

Substitution for FST73100M follows a strict comparison of the parameters that define electrical and mechanical fit within the Diodes, Rectifiers category. Key elements for substitution include:

• Diode Configuration: 1 Pair Common Cathode
• Technology: Schottky
• Voltage - DC Reverse (Vr) (Max)
• Current - Average Rectified (Io) (per Diode)
• Voltage - Forward (Vf) (Max) @ If
• Speed: Fast Recovery =< 500ns, > 200mA (Io)
• Current - Reverse Leakage @ Vr
• Operating Temperature - Junction
• Mounting Type: Chassis Mount
• Package / Case

Parts listed as substitutes must match or exceed these critical electrical and mechanical specifications. No substitution is accepted without explicit alignment in all provided parameters.

Parameter Comparison

Engineering Selection Recommendations

The FST73100M is classified as Obsolete. The substitute 83CNQ100 from SMC Diode Solutions maintains an Active product status and is ROHS3 Compliant with REACH status as REACH Affected. Both parts are at Moisture Sensitivity Level (MSL): 1 (Unlimited), which aligns with standard handling procedures. ECCN and HTSUS codes are equivalent and do not impact substitution in this category.

Frequently Asked Questions (FAQ)

Q1: What are the main criteria for substituting FST73100M with 83CNQ100?
A1: Substitution is strictly based on matching diode configuration, technology, voltage ratings, rectified current, forward voltage, recovery speed, reverse leakage, operating temperature range, mounting type, and package/case per input parameters.

Q2: Is there any compliance difference between FST73100M and 83CNQ100?
A2: 83CNQ100 is ROHS3 Compliant and REACH Affected. FST73100M compliance is not specified beyond ECCN and HTSUS, both parts sharing ECCN: EAR99 and HTSUS: 8541.10.0080.

Q3: How does the package/case variation affect compatibility?
A3: FST73100M uses D61-3M and 83CNQ100 uses PRM2. Mechanical interfacing should be verified with provided package/case data to ensure direct mounting compatibility.

Q4: Why is it necessary to find a substitute for FST73100M?
A4: The part is Obsolete and no longer in production, necessitating identification of compatible alternatives for continued procurement and system maintenance.

Q5: Are there considerations for operating temperature range between these parts?
A5: Both parts cover at least -55°C at their lower specification; 83CNQ100 provides an extended upper limit to 175°C, compared to 150°C for FST73100M. Selection based on this parameter is determined by application requirements as stated in the provided parameters.
