Key Parameters

Substitute Part Grouping Explanation

Substitution of the F1827HD1000 is based on the following critical electrical and mechanical parameters:

• Off-state voltage rating of 1 kV
• Gate trigger current (Igt) maximum of 150 mA
• Gate trigger voltage (Vgt) maximum of 3 V or lower
• Non-repetitive surge current (Itsm) capability of 400A or greater
• Series connection configuration with 1 SCR and 1 Diode
• Chassis mount packaging
• Operating temperature range of -40°C to 125°C

The VS-VSKH26/10 meets all critical substitution criteria within these parameters.

Parameter Comparison

Engineering Selection Recommendations

The VS-VSKH26/10 is qualified as a direct substitute for the F1827HD1000 based on electrical parameter equivalence and compliance certifications. The substitute part maintains identical off-state voltage, gate trigger current, and operating temperature specifications. The gate trigger voltage of the substitute is lower (2.5 V vs. 3 V maximum), which represents an improvement in gate sensitivity.

The VS-VSKH26/10 carries Active product status with ROHS3 compliance and REACH Unaffected designation, ensuring long-term availability and regulatory compliance. The primary design consideration is the package difference: the substitute uses ADD-A-PAK (3 + 4) format versus the original Module packaging. Physical mounting and thermal interface requirements must be evaluated for the specific application.

Frequently Asked Questions (FAQ)

Q: What electrical parameters determine substitution compatibility for the F1827HD1000?

A: The critical parameters are 1 kV off-state voltage, 150 mA maximum gate trigger current, gate trigger voltage of 3 V or lower, and 400A or greater non-repetitive surge current capability. The module must maintain series connection configuration with 1 SCR and 1 Diode.

Q: How does the VS-VSKH26/10 compare electrically to the F1827HD1000?

A: Both parts share identical off-state voltage (1 kV), gate trigger current (150 mA maximum), and operating temperature range (-40°C to 125°C). The substitute has a lower gate trigger voltage maximum (2.5 V vs. 3 V), indicating improved gate sensitivity. Non-repetitive surge current capability is equivalent or superior.

Q: What is the primary difference between these parts?

A: The packaging format differs. The F1827HD1000 uses standard Module packaging, while the VS-VSKH26/10 uses ADD-A-PAK (3 + 4) format. Both are chassis mount configurations. Physical dimensions, mounting hole patterns, and thermal interface characteristics must be verified for the specific application.

Q: Is the VS-VSKH26/10 suitable for new designs?

A: Yes. The VS-VSKH26/10 carries Active product status with current compliance certifications (ROHS3, REACH Unaffected), making it appropriate for new product development and long-term production.

Q: Are there any compliance considerations when substituting?

A: Both parts are RoHS compliant. The substitute carries ROHS3 certification and is REACH Unaffected, providing enhanced regulatory alignment for current manufacturing standards.
