Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ABLS-8.000MHZ-B4H-T is determined by strict equivalence across the following critical parameters:

• Frequency: 8 MHz (exact match required)
• Frequency Tolerance: ±30ppm (exact match required)
• Load Capacitance: 18pF (exact match required)
• ESR: 80 Ohms (exact match required)
• Package / Case: HC-49/US (exact match required)
• Operating Mode: Fundamental (exact match required)
• Operating Temperature Range: -20°C ~ 70°C (exact match required)
• Mounting Type: Surface Mount (exact match required)

The substitute part ABLS-8.000MHZ-B-4-Y-T meets all these criteria and is therefore classified as a parametric equivalent within the ABLS series.
