Key Parameters

Substitute Part Grouping Explanation

The SL1021B090X qualifies as a direct substitute for the PMT809014 based on the following critical parameters:

• Voltage Rating: Both parts specify 90V DC spark-over voltage
• Discharge Current: Both rated at 20000A (20kA) impulse discharge current
• Pole Configuration: Both are 3-pole devices
• Mounting Architecture: Both use through-hole mounting with identical Axial Cylinder, 3 Lead (T-Shape) package
• Fail Mode: Both configured as non-fail-short devices
• Regulatory Compliance: Both meet ROHS3 requirements and carry identical ECCN and HTSUS classifications

The substitution is valid across all specified electrical and mechanical parameters. The primary distinction is product lifecycle status: PMT809014 is obsolete while SL1021B090X maintains active status.

Parameter Comparison

Engineering Selection Recommendations

The SL1021B090X is the direct equivalent for PMT809014 applications. Selection of the active substitute is justified by:

• Electrical Equivalence: Identical voltage and current ratings ensure functional compatibility in all circuit applications
• Mechanical Compatibility: Matching package geometry and lead configuration enable direct PCB footprint compatibility
• Regulatory Alignment: Both parts maintain ROHS3 compliance and identical trade classification codes
• Supply Continuity: Active product status of SL1021B090X provides sustained availability and manufacturing support, eliminating obsolescence risk associated with PMT809014

No design modifications or circuit re-qualification are required when transitioning from PMT809014 to SL1021B090X.

Frequently Asked Questions (FAQ)

Q: Can SL1021B090X be used as a direct replacement for PMT809014 without PCB modifications?
