Key Parameters

Substitute Part Grouping Explanation

Substitute snap action switch components are identified by matching all key electrical and mechanical parameters. Substitution is based only on circuit type (SPDT), switch function (On-Mom), current rating, voltage rating, actuator type, mounting type, termination style, and critical travel/force parameters. The substitute DB3C-A1LC matches the required circuit, switch function, electrical parameters, actuator style, and termination. Additional consideration is given for manufacturer series if explicitly required.

Parameter Comparison

Engineering Selection Recommendations

DA3C-D1LB is obsolete and RoHS non-compliant. Substitute DB3C-A1LC is active and ROHS3 compliant. For applications requiring RoHS compliance or ongoing supply, DB3C-A1LC is suitable based on the provided part status and compliance information.
