Substitute Part Grouping Explanation

Substitution eligibility for the TP11SHWKE is determined by strict equivalence across the following critical parameters:

• Circuit configuration: SPST-NO
• Switch function: Off-Mom (momentary operation)
• Current rating: 0.4VA (AC/DC)
• Voltage rating: 20V AC and 20V DC
• Mounting type: Panel Mount, Rear
• Panel cutout dimensions: Circular - 4.95mm Dia
• Actuator type: Round, Plunger
• Termination style: Wire Wrap
• Operating temperature range: -30°C to 85°C
• Electrical life: 60,000 Cycles

The TP11SHWPE meets all these criteria and qualifies as a direct substitute. This part maintains identical electrical specifications, mechanical dimensions, and functional characteristics while offering active product status and improved compliance documentation.

Parameter Comparison

Engineering Selection Recommendations

The TP11SHWPE is the appropriate substitute for the obsolete TP11SHWKE. Both components share identical electrical and mechanical specifications, ensuring direct functional compatibility in existing circuit designs and panel assemblies.

The TP11SHWPE offers the advantage of active product status, providing assured long-term availability and supply chain stability. Both parts maintain equivalent RoHS compliance and moisture sensitivity ratings. The TP11SHWPE carries REACH Affected status compared to the TP11SHWKE's REACH Unaffected designation; however, this distinction does not affect component functionality or electrical performance.

For applications currently using the TP11SHWKE, transition to the TP11SHWPE requires no design modifications, circuit alterations, or panel cutout changes. Pin configuration, termination method, and all operational parameters remain identical.
