Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SL1024B300RG is determined by strict equivalence across the following critical parameters:

• Voltage - DC Spark Over (Nominal): 300 V
• Impulse Discharge Current (8/20µs): 20000A (20kA)
• Number of Poles: 3
• Fail Short: Yes
• Mounting Type: Through Hole
• Package / Case: Axial Cylinder, 3 Lead (Radial Bend)
• RoHS Status: ROHS3 Compliant

The SL1021B300RF meets all substitution criteria. Both parts share identical electrical ratings, mechanical configuration, and compliance certifications. The primary distinction is product status: SL1024B300RG is obsolete, while SL1021B300RF is active.
