Engineering Selection Recommendations

The SCHURTER 1241.6402 is the appropriate substitute for the obsolete 1241.6407. Both components are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements. The 1241.6402 maintains identical electrical and mechanical specifications while offering active product status and extended illumination voltage compatibility (5–28VDC versus 24VDC fixed).

For applications currently using the 1241.6407, direct replacement with the 1241.6402 is supported by matching circuit topology, current and voltage ratings, mechanical life specifications, and physical mounting dimensions. The expanded illumination voltage range of the 1241.6402 provides design flexibility without compromising compatibility with existing 24VDC illumination circuits.

Frequently Asked Questions (FAQ)

Q: Can the 1241.6402 directly replace the 1241.6407 in existing designs?

A: Yes. Both components share identical SPST-NO circuit configuration, 125mA current rating, 48V voltage rating, momentary switch function, anti-vandal design, yellow LED illumination, IP65 ingress protection, and 30.30mm panel cutout dimensions. Physical and electrical compatibility is maintained.

Q: What is the significance of the illumination voltage difference?

A: The 1241.6407 specifies 24VDC nominal illumination voltage, while the 1241.6402 operates across 5–28VDC. This expanded range in the 1241.6402 allows operation in systems with varying illumination supply voltages without circuit modification. Existing 24VDC illumination circuits remain fully compatible.

Q: Why is the 1241.6407 listed as obsolete?

A: Product obsolescence indicates the manufacturer has discontinued production. The 1241.6402 serves as the active equivalent, ensuring continued availability and support for this component category.

Q: Are there packaging differences between these parts?

A: The 1241.6407 is listed with packaging designation "-" while the 1241.6402 is supplied in Bulk packaging. Both use Wire Leads termination style.

Q: Do both parts meet current compliance standards?

A: Yes. Both the 1241.6407 and 1241.6402 are ROHS3 compliant and REACH unaffected, meeting current environmental regulations.
