Key Parameters

Substitute Part Grouping Explanation

Substitution of the T103KAKE is determined by strict equivalence across the following critical parameters:

• Circuit Configuration: SPDT topology must be maintained
• Switch Function: On-Off-On operation required
• Electrical Ratings: 0.4VA at 20V AC/DC
• Mechanical Interface: Panel mount, right angle orientation with 6.35mm circular cutout and 1/4-40 bushing thread
• Actuator Specifications: Locking lever with 16.26mm length
• Termination: PC pin connection
• Environmental Performance: Operating temperature -30°C ~ 85°C, 30,000 cycle electrical life

The T103KAPE qualifies as a direct substitute, maintaining identical electrical and mechanical specifications while offering active product status and improved availability.

Parameter Comparison

Engineering Selection Recommendations

The T103KAPE is a direct functional and mechanical equivalent to the T103KAKE. Both components share identical electrical specifications, mechanical interfaces, and environmental operating parameters. The primary distinction is product lifecycle status: the T103KAKE is obsolete while the T103KAPE maintains active production status.

For new designs and ongoing system support, the T103KAPE is the appropriate selection. Both components meet RoHS compliance requirements, with the T103KAPE offering the advantage of current manufacturing availability and supply chain continuity. No design modifications or re-qualification are required when transitioning from T103KAKE to T103KAPE.
