Key Parameters

Substitute Part Grouping Explanation

Substitution of the B512F-2-YEC is determined by strict equivalence across the following critical parameters:

• Bridge, single-phase SCR/diode structure with identical layout (Layout 1)
• Identical component count: 2 SCRs and 2 Diodes
• Matching off-state voltage rating: 600V
• Identical gate trigger specifications: Vgt Max 2.5V, Igt Max 60mA
• Identical surge current rating: 250A @ 60Hz
• Matching operating temperature range: -40°C to 125°C
• Chassis mount configuration
• Common base product number: B512

The B512FSE-2T-YEB meets all these criteria and is classified as an active product, making it a direct functional equivalent for the obsolete B512F-2-YEC.
