Key Parameters

Substitute Part Grouping Explanation

Substitute selection for the RR2LAM4STR is strictly based on matching its key electrical parameters and mechanical characteristics. The essential parameters for establishing substitute compatibility are:

• Voltage - DC Reverse (Vr) (Max)
• Current - Average Rectified (Io)
• Voltage - Forward (Vf) (Max) @ If
• Speed (Recovery Time)
• Current - Reverse Leakage @ Vr
• Mounting Type
• Package / Case
• Supplier Device Package
• Operating Temperature (Junction)
• Environmental and Regulatory Compliance (RoHS, REACH, ECCN, MSL)

Only parts with identical or directly matching specifications to these key parameters are categorized as valid substitutes.

Parameter Comparison

Engineering Selection Recommendations

Both RR2LAM4STR and RR2LAM4STFTR are categorized as Not For New Designs. Environmental and regulatory compliance statuses match (RoHS3 Compliant, MSL 1, REACH Unaffected, ECCN EAR99). The RR2LAM4STFTR includes automotive grade classification and AEC-Q101 qualification, meeting stringent quality requirements in addition to standard compliance. Selection should consider only current inventory status and the identical electrical, mechanical, and regulatory features indicated.
