Key Parameters

Substitute Part Grouping Explanation

Substitution of the BB153,115 is determined by strict equivalence across the following electrical and mechanical parameters:

• Capacitance characteristics: Capacitance value at specified reverse voltage (2.754 pF @ 28V, 1MHz) and capacitance ratio (15, C1/C28 condition)
• Voltage rating: Peak reverse voltage of 32 V
• Diode configuration: Single junction topology
• Operating temperature range: -55°C to 125°C (TJ)
• Package compatibility: Surface mount in SOD-323 (SC-76) form factor
• Regulatory compliance: ROHS3 compliance and REACH unaffected status

The BB172X meets all these criteria and is classified as an active product, providing direct functional and mechanical compatibility with the obsolete BB153,115.
