Key Parameters

Substitute Part Grouping Explanation

The SCHURTER 1241.6401 qualifies as a direct substitute for the 1241.6422 based on the following critical parameters:

• Circuit Configuration: Both parts maintain SPST-NO circuit topology
• Current Rating: Both rated at 125mA DC
• Voltage Rating: Both rated at 48V DC
• Mounting Configuration: Both feature panel mount, front installation with identical 30.30mm circular cutout
• Actuator Design: Both use round, flush button actuators with silver coloring
• Illumination Type: Both incorporate green LED illumination
• Ingress Protection: Both meet IP65 specification
• Mechanical and Electrical Life: Both rated for 1,000,000 cycles
• Operating Temperature: Both operate across -20°C to 60°C range
• Termination: Both use wire leads

The primary distinction is the illumination voltage specification: the 1241.6422 operates at 12VDC nominal, while the 1241.6401 accepts 5–28VDC. This expanded voltage range in the substitute part provides greater flexibility in circuit design without compromising functional equivalence.

Parameter Comparison

Engineering Selection Recommendations

The SCHURTER 1241.6401 is the appropriate selection for applications currently using or requiring the 1241.6422. The substitute part maintains identical electrical and mechanical specifications across all critical parameters, ensuring direct functional compatibility.

The 1241.6401 offers the additional advantage of active product status, ensuring continued availability and supply chain reliability. The expanded illumination voltage range (5–28VDC versus 12VDC) provides design flexibility without introducing compatibility constraints. Both parts carry identical regulatory classifications (REACH Unaffected, EAR99) and comply with the same tariff codes.

For new designs or system replacements, the 1241.6401 is the recommended choice due to its active status and broader voltage tolerance for LED illumination circuits.

Frequently Asked Questions (FAQ)

Q: Can the 1241.6401 be used as a direct replacement for the 1241.6422 in existing installations?

A: Yes. Both parts share identical circuit configuration (SPST-NO), current and voltage ratings (125mA at 48V DC), mounting geometry (30.30mm panel cutout), and mechanical specifications (1,000,000 cycle life). Physical installation and electrical integration are identical.

Q: What is the significance of the different illumination voltage specifications?

A: The 1241.6422 requires 12VDC nominal for LED illumination, while the 1241.6401 accepts 5–28VDC. This difference does not affect substitution compatibility. If your circuit supplies 12VDC to the illumination circuit, both parts function identically. The 1241.6401's broader voltage tolerance simply provides additional design flexibility for future applications.

Q: Why is the 1241.6422 classified as obsolete?

A: Obsolete status indicates the part is no longer in active production. The 1241.6401 remains in active production and serves the same functional role, making it the appropriate long-term solution for supply continuity.

Q: Are there packaging differences between these parts?

A: The 1241.6422 is packaged as individual units (indicated by "-" in packaging specification), while the 1241.6401 is supplied in bulk packaging. This distinction affects procurement and inventory management but does not impact electrical or mechanical performance.

Q: Do both parts meet the same regulatory and compliance standards?

A: Yes. Both parts carry identical REACH status (REACH Unaffected), ECCN classification (EAR99), and HTSUS tariff codes (8536.50.9031). Regulatory compliance is equivalent.
