Substitute Part Grouping Explanation

Substitution eligibility for the SCHURTER 1241.6421 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 geometry (Round, Button, Flush)
• Panel cutout dimensions (30.30mm circular)
• Ingress protection rating (IP65)
• Operating temperature range (-20°C to +60°C)
• Mechanical and electrical life (1,000,000 cycles minimum)
• Termination style (Wire Leads)

The SCHURTER 1241.6400 meets all substitution criteria as an active product within the same MCS series, maintaining identical electrical specifications, mechanical dimensions, and environmental ratings.

Frequently Asked Questions (FAQ)

Q: Can the 1241.6400 be used as a direct replacement for the 1241.6421 in existing applications?

A: Yes. The 1241.6400 maintains identical electrical ratings (125mA at 48V DC), circuit configuration (SPST-NO), mechanical dimensions (30.30mm panel cutout), and environmental specifications (IP65, -20°C to +60°C). The illumination voltage range of the 1241.6400 (5 ~ 28VDC) fully supports the 12VDC nominal requirement of the original part.

Q: What is the primary difference between these two parts?

A: The 1241.6421 is obsolete, while the 1241.6400 is in active production. The 1241.6400 features an expanded illumination voltage range (5 ~ 28VDC versus 12VDC fixed) and carries RoHS3 compliance certification.

Q: Are there packaging differences between the 1241.6421 and 1241.6400?

A: The 1241.6421 is supplied with unspecified packaging, while the 1241.6400 is packaged in trays. Both use identical wire lead termination.

Q: Does the wider illumination voltage range of the 1241.6400 affect circuit design?

A: No. The 1241.6400 is fully backward compatible. Existing circuits designed for 12VDC illumination operate identically with the 1241.6400, as 12VDC falls within its 5 ~ 28VDC specification range.

Q: Are regulatory certifications equivalent between these parts?

A: Both parts carry REACH Unaffected and EAR99 ECCN classifications. The 1241.6400 additionally carries RoHS3 compliance, making it suitable for applications requiring current regulatory compliance.
