Substitute Part Grouping Explanation

Substitution of the K12GOBK1.59N is based on strict electrical and mechanical parameter matching within the K12 series. The substitute part K12GOBK1.56/12N qualifies as an equivalent based on the following criteria:

Electrical Parameters: Both parts maintain identical circuit configuration (DPST-NO), switch function (Off-Mom-Mom), current rating (100mA DC), and voltage rating (30V DC).

Mechanical Parameters: Both parts feature identical mounting type (through hole), actuator type (round button), termination style (PC pin), and ingress protection rating (IP40).

Environmental Specifications: Both parts operate across the same temperature range (-40°C to 85°C) and deliver equivalent electrical life (1,000,000 cycles) with tactile feedback.

Compliance: Both parts meet RoHS requirements and share identical moisture sensitivity level (MSL 1).

The primary distinction is product status: K12GOBK1.59N is obsolete, while K12GOBK1.56/12N is active production, making it the recommended substitute for new applications and replacements.
