Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 19218-11 are qualified based on the following critical electrical and mechanical parameters:

• Voltage Rating: 600V (exact match required)
• Current Rating: 125A (exact match required)
• Type: Switch (functional equivalence)
• RoHS3 Compliance: Required for environmental and regulatory alignment
• REACH Unaffected Status: Required for supply chain continuity

The VKA3125N from Altech Corporation meets all substitution criteria, maintaining identical voltage and current specifications while providing active product status and equivalent compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The VKA3125N is a direct functional equivalent for the obsolete 19218-11. Both components share identical electrical specifications (600V, 125A) and maintain equivalent compliance certifications (ROHS3 Compliant, REACH Unaffected, EAR99 classification). The VKA3125N offers the advantage of active product status, ensuring continued availability and supply chain support. Packaging differs (bulk versus box), which may affect logistics and inventory management but does not impact electrical or mechanical compatibility.

Frequently Asked Questions (FAQ)

Q: Can the VKA3125N directly replace the 19218-11 in existing installations?

A: Yes. Both components are rated for 600V and 125A operation with identical compliance certifications. Mechanical mounting and terminal configurations must be verified against installation documentation to ensure physical fit.

Q: Why is the 19218-11 classified as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The VKA3125N provides equivalent electrical performance with active manufacturing support.

Q: Are there differences in packaging between these parts?

A: The 19218-11 is supplied in bulk packaging, while the VKA3125N is supplied in box packaging. This affects handling and storage but not component functionality.

Q: Do both parts meet current environmental regulations?

A: Yes. Both the 19218-11 and VKA3125N are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory requirements.

Q: What is the inventory status for these parts?

A: The 19218-11 has 874 pieces in stock (new original). The VKA3125N has 843 pieces in stock (new original, active product).
