Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MX3A-L1DN is determined by strict equivalence across the following critical parameters:

• Circuit configuration: SPST-NO
• Switch function: Off-Mom (momentary operation)
• Current rating: 10mA AC/DC
• Voltage rating: 12V AC and 12V DC
• Mounting type: Through hole
• Actuator type: Plunger for cap
• Actuator color: Red
• Termination style: PC pin
• Ingress protection: IP40
• Operating temperature range: -10°C to 70°C
• Mechanical life: 50,000,000 cycles

The MX3A-L1DN has one identified substitute within the MX series: MX3A-L1NN. This substitute maintains identical electrical specifications, mechanical characteristics, and physical form factor while offering active product status and improved availability.

Parameter Comparison

Engineering Selection Recommendations

The MX3A-L1NN is a direct functional equivalent to the MX3A-L1DN. Both components share identical electrical ratings, mechanical specifications, and physical characteristics. The primary distinction is product status: the MX3A-L1DN is obsolete while the MX3A-L1NN is active.

For new designs and ongoing production, the MX3A-L1NN is the appropriate selection. It provides equivalent performance with the advantage of current manufacturer support and active inventory availability. The MX3A-L1NN carries ROHS3 compliance, meeting current regulatory requirements.

For legacy system maintenance where the original MX3A-L1DN is specified, the MX3A-L1NN provides drop-in compatibility without circuit redesign or functional compromise.
