Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for tactile switches is determined by compatibility across the following critical parameters:

• Circuit configuration (SPST-NO maintained)
• Contact rating voltage and current capacity
• Actuator type and orientation (round button, top actuated)
• Mounting method (through hole)
• Mechanical life rating
• RoHS and regulatory compliance status

The SCHURTER Inc. 1241.1624.41 qualifies as a substitute based on matching circuit topology, mounting configuration, and mechanical life specification. Both components maintain SPST-NO functionality with through-hole termination and equivalent mechanical durability.

Parameter Comparison

Engineering Selection Recommendations

The SCHURTER 1241.1624.41 is an active product with current manufacturing support, addressing the obsolescence status of the E-Switch 320.02E11.08WHT. Both components maintain ROHS3 compliance and equivalent mechanical life ratings of 1,000,000 cycles.

The substitute component offers an extended operating temperature range (-40°C to 85°C versus -20°C to 70°C) and higher contact current capacity (0.05A versus 0.025A), providing design margin for applications within the original voltage specification. The SCHURTER component features IP40 ingress protection, not specified for the original part.

Physical differences include increased actuator height (16.60mm versus 14.40mm), reduced outline footprint (11.40mm x 11.40mm versus 12.40mm x 12.40mm), and reduced switch travel (0.35mm versus 0.60mm). These dimensional variations require PCB layout verification and mechanical clearance assessment.

Frequently Asked Questions (FAQ)

Q: Can the SCHURTER 1241.1624.41 directly replace the E-Switch 320.02E11.08WHT in existing designs?

A: Direct replacement requires verification of three factors: PCB layout accommodation for the increased actuator height (16.60mm), mechanical clearance for the reduced outline dimensions, and functional compatibility with the reduced switch travel (0.35mm). The higher operating force (180gf versus 135gf) may affect user interface feel.

Q: What are the voltage and current rating differences between these components?

A: The E-Switch component is rated 0.025A @ 50VDC. The SCHURTER substitute is rated 0.05A @ 42VDC. Applications operating at the original 50VDC specification must confirm the substitute's 42VDC rating is acceptable for the circuit design.

Q: Are both components RoHS compliant?

A: Yes, both the E-Switch 320.02E11.08WHT and SCHURTER 1241.1624.41 are ROHS3 compliant and REACH unaffected.

Q: What is the significance of the product status difference?

A: The E-Switch component is obsolete with no ongoing manufacturing. The SCHURTER component is active with current production support, ensuring long-term availability for new designs and ongoing procurement.

Q: How do the mechanical life ratings compare?

A: Both components specify 1,000,000 cycles mechanical life, providing equivalent durability for switch actuation applications.
