Core Substitution Parameters:

• Frequency: 33.333 MHz (exact match required)
• Output Type: CMOS (exact match required)
• Supply Voltage: 3.3V (exact match required)
• Function: Enable/Disable (exact match required)
• Package / Case: 4-SMD, No Lead (exact match required)
• Size / Dimension: 5.00mm x 3.20mm (exact match required)
• Height - Seated (Max): 1.40mm (exact match required)
• Mounting Type: Surface Mount (exact match required)
• Operating Temperature: -10°C ~ 70°C (exact match required)
• Current - Supply (Max): 30mA (exact match required)
• Manufacturer: TXC CORPORATION (exact match required)
• Series: 7C (exact match required)

Variable Parameters Allowing Substitution:

• Frequency Stability: Tolerance variation permitted (±25ppm, ±50ppm, ±100ppm)
• Product Status: Active substitutes acceptable for Obsolete main part
• Packaging Format: Tape & Reel (TR) or standard packaging acceptable

The substitute parts 7C-33.3330MBB-T and 7C-33.3330MBC-T meet all core substitution criteria while differing only in frequency stability tolerance and product status.
