SCHURTER 0041.2302 Equivalent & Substitute Parts

Part Overview

The SCHURTER 0041.2302 is a pushbutton switch with DPST-NO (Double Pole Single Throw - Normally Open) circuit configuration, rated for 5A AC at 250V and 200mA DC. This component features standard illuminated panel mount construction with front mounting orientation and rectangular button actuator. The product is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system maintenance and new design implementations where this switch type is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SCHURTER 0041.2302 is determined by the following critical parameters:

Circuit Configuration Match: The substitute must maintain DPST-NO circuit topology to preserve electrical functionality in the target application.

Voltage Compatibility: The substitute must support minimum 250V AC rating. DC voltage rating of the substitute may differ provided it meets or exceeds application requirements.

Current Capacity: The substitute must support minimum 5A AC current rating. Higher current ratings provide design margin and are acceptable.

Switch Function: Off-Mom (momentary) operation must be preserved.

Mounting Compatibility: Panel mount configuration is required. Mounting orientation (front vs. snap-in) and panel cutout dimensions must be evaluated against physical installation constraints.

Termination Consideration: Solder lug termination of the original part may require adapter consideration if substitute uses quick connect termination.

Environmental Compliance: RoHS3 compliance is mandatory for modern applications.

The E-Switch PB1973HBLKGILEF3 qualifies as a functional substitute based on matching circuit configuration (DPST-NO), momentary operation, and exceeding voltage and current ratings. Mechanical life specification of the substitute (30,000 cycles) is lower than the original part, requiring application-specific cycle life evaluation.

Parameter Comparison

Engineering Selection Recommendations

Primary Consideration - Product Status: The SCHURTER 0041.2302 is obsolete. The E-Switch PB1973HBLKGILEF3 is actively manufactured and represents the available alternative for new procurement and system redesign.

Electrical Compatibility: Both components meet 250V AC voltage requirements and DPST-NO circuit topology. The substitute's higher AC current rating (15A vs. 5A) provides design margin for AC applications. However, the substitute's DC voltage rating (125V) is lower than the original (250V), requiring verification that DC application voltages do not exceed 125V.

Mechanical and Electrical Life Trade-off: The substitute exhibits significantly lower mechanical life (30,000 vs. 2,000,000 cycles) and electrical life (10,000 vs. 50,000 cycles). Applications requiring high-cycle operation must evaluate whether the substitute's life specifications are adequate for the intended duty cycle.

Physical Integration: The substitute uses snap-in mounting with rectangular panel cutout (19.20mm x 13.00mm) versus the original's front-mount circular cutout (16.20mm diameter). Panel modification or adapter hardware may be necessary. Termination differs (quick connect vs. solder lug), requiring wiring harness adaptation.

Temperature Range: The substitute's operating temperature range (-10°C to 55°C) is narrower than the original (-40°C to 55°C). Applications requiring operation below -10°C are not suitable for this substitute.

Compliance: Both components are ROHS3 compliant and REACH unaffected, meeting modern regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can the E-Switch PB1973HBLKGILEF3 directly replace the SCHURTER 0041.2302 without modification?

A: Direct replacement without modification is not possible. The substitute requires panel cutout modification (from circular 16.20mm to rectangular 19.20mm x 13.00mm), termination adapter (quick connect vs. solder lug), and mounting method change (snap-in vs. front mount). Electrical compatibility exists for AC applications within the specified voltage and current parameters.

Q: What is the impact of the lower mechanical life rating on the substitute?

A: The substitute's mechanical life of 30,000 cycles is substantially lower than the original's 2,000,000 cycles. Applications with high switching frequency or long operational life requirements must evaluate whether this specification is acceptable. Calculate expected cycle count over the product's intended service life to determine suitability.

Q: Is the substitute suitable for DC applications?

A: The substitute's DC voltage rating is 125V, compared to the original's 250V. DC applications must not exceed 125V. If the application requires 250V DC operation, this substitute is not suitable. Verify the actual DC voltage requirement before selection.

Q: What is the significance of the narrower operating temperature range?

A: The substitute operates from -10°C to 55°C, versus the original's -40°C to 55°C. Applications requiring operation below -10°C cannot use this substitute. Verify the minimum operating temperature requirement of the target application.

Q: Are there any compliance differences between the two parts?

A: Both components are ROHS3 compliant and REACH unaffected. No compliance disadvantage exists with the substitute for modern applications requiring these certifications.

Q: What termination options are available for the substitute?

A: The E-Switch PB1973HBLKGILEF3 uses quick connect 0.187" (4.7mm) termination. If solder lug termination is required, wiring harness modification or adapter hardware is necessary. Verify termination compatibility with the target circuit board or wiring harness design.
