Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SCHURTER 1241.6423 is determined by strict equivalence across the following critical parameters:

• Circuit configuration: SPST-NO
• Switch function: Off-Mom (momentary operation)
• Current rating: 125mA DC
• Voltage rating: 48V DC
• Mounting type: Panel Mount, Front
• Actuator type: Round, Button, Flush
• Illumination type: LED, Yellow
• Ingress protection: IP65
• Panel cutout dimensions: Circular 30.30mm Dia
• Termination style: Wire Leads
• Operating temperature range: -20°C to 60°C
• Mechanical and electrical life: 1,000,000 cycles minimum

The SCHURTER 1241.6402 meets all substitution criteria. The primary distinction is the illumination voltage range, which expands from a fixed 12 VDC specification to a broader 5–28 VDC range, providing greater flexibility in circuit design while maintaining all other functional and mechanical parameters.

Engineering Selection Recommendations

The SCHURTER 1241.6402 is the direct functional equivalent for the obsolete 1241.6423. Selection of the 1241.6402 is supported by the following factors:

• Active product status ensures ongoing availability and supply chain continuity
• RoHS3 compliance of the 1241.6402 provides enhanced environmental and regulatory alignment
• Identical electrical and mechanical specifications across all critical parameters
• Expanded illumination voltage range (5–28 VDC versus fixed 12 VDC) provides design flexibility without compromising performance
• Identical panel cutout dimensions and mounting configuration ensure direct mechanical compatibility
• Both parts maintain equivalent ingress protection, operating temperature range, and lifecycle ratings

Frequently Asked Questions (FAQ)

Q: Can the 1241.6402 be used as a direct replacement for the 1241.6423 in existing applications?

A: Yes. The 1241.6402 maintains identical electrical ratings (125mA DC, 48V DC), circuit configuration (SPST-NO), switch function (Off-Mom), mounting type (Panel Mount, Front), and mechanical specifications (30.30mm circular cutout, wire leads). The expanded illumination voltage range does not affect compatibility.

Q: What is the significance of the illumination voltage difference between the two parts?

A: The 1241.6423 specifies a fixed illumination voltage of 12 VDC, while the 1241.6402 accepts 5–28 VDC. This expanded range in the substitute part allows operation across a broader range of circuit designs without requiring voltage regulation modifications. Both parts use identical yellow LED illumination.

Q: Are there packaging differences between these parts?

A: The 1241.6423 is listed with packaging designation "-" (undefined), while the 1241.6402 is supplied in Bulk packaging. This distinction does not affect electrical or mechanical compatibility; it reflects only the distribution format.

Q: Why is the 1241.6423 classified as obsolete?

A: Obsolescence indicates the part is no longer in active production. The 1241.6402 serves as the current production equivalent within the SCHURTER MCS series, offering identical functionality with enhanced regulatory compliance (RoHS3).

Q: Are the mechanical life and electrical life ratings equivalent?

A: Yes. Both parts are rated for 1,000,000 mechanical cycles and 1,000,000 electrical cycles, ensuring equivalent durability and operational lifespan.

Q: What compliance certifications apply to the substitute part?

A: The 1241.6402 is RoHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic components.
