Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SCHURTER 1241.6631.1120000 is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Circuit Configuration: SPDT
• Switch Function: On-Mom (Momentary)
• Current Rating: 5A (AC)
• Voltage Rating: 125V AC
• Mounting Type: Panel Mount, Front
• Type: Anti-Vandal
• Actuator Type: Round, Button, Flush
• Termination Style: Quick Connect - 0.110" (2.8mm)
• Ingress Protection: IP40
• Panel Cutout Dimensions: Circular - 22.10mm Dia
• Series: MSM

Acceptable Parameter Variations:

• Operating Temperature Range: Extended ranges are acceptable (original: -25°C ~ 85°C; substitute may extend to -30°C ~ 85°C)
• Mechanical Life: Substitute values must meet or exceed original specification (original: 1,500,000 cycles)
• Product Status: Active status is preferred for ongoing availability
• RoHS and REACH Compliance: Must maintain or exceed original compliance level

The substitute part SCHURTER 3-145-478 meets all mandatory matching parameters and maintains equivalent electrical and mechanical performance characteristics within the MSM series.

Parameter Comparison

Engineering Selection Recommendations

The SCHURTER 3-145-478 is the manufacturer-recommended substitute for the obsolete 1241.6631.1120000. Both components are manufactured by SCHURTER Inc. within the MSM series and share identical electrical ratings, circuit configuration, and mechanical interface specifications.

Selection Basis:

The substitute part maintains active product status, ensuring ongoing availability and supply chain support. All critical functional parameters—SPDT circuit, 5A/125V AC rating, momentary switch function, anti-vandal construction, and quick connect termination—are identical between the original and substitute.

The substitute provides an extended operating temperature range (-30°C to 85°C versus -25°C to 85°C), offering improved performance in lower-temperature environments. However, the original part specifies higher mechanical life (1,500,000 cycles versus 200,000 cycles). Applications requiring the original mechanical life specification should evaluate this difference against actual duty cycle requirements.

Both components maintain equivalent ingress protection (IP40), panel cutout dimensions (22.10mm circular), and actuator characteristics (round flush button, silver color).

Frequently Asked Questions (FAQ)

Q: Can the SCHURTER 3-145-478 be used as a direct replacement for 1241.6631.1120000?

A: Yes. Both parts share identical electrical ratings (5A, 125V AC), circuit configuration (SPDT), switch function (momentary), mounting interface (panel mount, front), and termination style (quick connect 0.110"). The panel cutout dimensions and actuator specifications are identical, enabling direct mechanical and electrical substitution.

Q: What is the difference in mechanical life between these parts?

A: The original 1241.6631.1120000 specifies 1,500,000 mechanical cycles, while the substitute 3-145-478 specifies 200,000 mechanical cycles. Applications with high-frequency switching requirements should evaluate whether the substitute's mechanical life meets the intended duty cycle.

Q: Does the extended temperature range of the substitute affect compatibility?

A: No. The substitute's extended operating range (-30°C to 85°C) is a performance enhancement. Applications operating within the original range (-25°C to 85°C) will function identically. Applications requiring operation below -25°C benefit from the substitute's extended lower limit.

Q: Are there packaging or inventory differences?

A: The original part is obsolete with 754 units in stock. The substitute is active production with 1041 units available, providing improved long-term supply availability.

Q: What electrical specifications must match for substitution?

A: Current rating (5A AC), voltage rating (125V AC), and circuit configuration (SPDT) are non-negotiable matching parameters. Any deviation in these specifications disqualifies a part from substitution.

Q: Are both parts RoHS compliant?

A: The original 1241.6631.1120000 is ROHS3 compliant. RoHS compliance status for the substitute 3-145-478 is not specified in the provided data.
