Key Parameters

Substitute Part Grouping Explanation

Substitution is determined strictly based on matching the following parameters: constant current output (700mA), maximum output voltage (32V), buck topology, one output channel, analog dimming capability, remote on/off and SCP features, through-hole 7-SIP package, input voltage range (7V–32V), 95% efficiency, and mechanical dimensions within practical tolerance. Product status and compliance form the final filters for viable substitutes. The substitute part, LEDdynamics 3021-D-I-700, matches all these mandatory criteria.

Parameter Comparison

Engineering Selection Recommendations

Selection must be based on product status and available compliance information. The 7021-D-I-700 is obsolete, which necessitates substitution. The 3021-D-I-700 is active and matches all specified electrical and mechanical parameters. Both models share the same ECCN and HTSUS. The substitute part lists RoHS3 compliance, while RoHS information for the 7021-D-I-700 is not provided.
