D101J12S2APQF Rocker Switch SPDT 4A 125V - Equivalent & Substitute Parts

Part Overview

The D101J12S2APQF is a panel-mount rocker switch manufactured by C&K, featuring Single Pole Double Throw (SPDT) configuration with 4A AC current rating at 125V. This part is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and component procurement.

The D101J12S2APQF operates as an On-On switch with a concave black actuator, designed for snap-in installation with right-angle orientation. The part carries cULus approval and maintains RoHS compliance. Due to its obsolete status, sourcing equivalent active-production alternatives ensures supply chain continuity and long-term availability.

Substitute Part Grouping Explanation

Substitution eligibility for the D101J12S2APQF is determined by strict equivalence across the following critical parameters:

• Circuit Configuration: SPDT (Single Pole Double Throw)
• Switch Function: On-On operation
• Current Rating: 4A AC minimum
• Voltage Rating: 125V AC minimum
• Mounting Type: Panel Mount, Snap-In, Right Angle
• Actuator Type: Concave (Curved)
• Actuator Color: Black
• Termination Style: PC Pin
• Panel Cutout Dimensions: Rectangular - 19.20mm x 12.90mm
• Operating Temperature Range: -30°C to 65°C minimum
• Electrical Life: 10,000 Cycles minimum
• Approval Agency: cULus certification

The D101J12S2APQA meets all substitution criteria as an active-production equivalent from the same manufacturer (C&K) and base product series (D101J). Both parts share identical electrical specifications, mechanical dimensions, and regulatory certifications, with the primary distinction being product status and packaging configuration.
