Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 9B-8.192MAAJ-B are selected based on strict electrical and mechanical parameter matching. The primary substitution criteria are:

Critical Parameters (Must Match Exactly):

• Frequency: 8.192 MHz
• Load Capacitance: 18pF
• ESR: 80 Ohms
• Operating Mode: Fundamental
• Package / Case: HC-49/US
• Mounting Type: Through Hole
• Operating Temperature Range: -20°C ~ 70°C

Allowable Variation:

• Frequency Stability: Substitute parts with equal or tighter (lower) frequency stability tolerance are acceptable. The main part specifies ±30ppm; substitutes with ±10ppm, ±20ppm, or ±30ppm stability are functionally compatible.

All substitute parts listed maintain identical mechanical dimensions, electrical characteristics, and environmental compliance ratings. Substitutes are sourced from Abracon LLC, an active manufacturer, ensuring long-term component availability.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent (Identical Specifications): ABL-8.192MHZ-B4Y-T is the direct equivalent to 9B-8.192MAAJ-B, matching all electrical parameters including ±30ppm frequency stability. This part is manufactured by Abracon LLC with active product status, ensuring ongoing availability and supply chain continuity.

Enhanced Performance Alternatives: ABL-8.192MHZ-B1U-T and ABL-8.192MHZ-B2 provide tighter frequency stability tolerances (±10ppm and ±20ppm respectively) while maintaining all other electrical and mechanical specifications. These parts are suitable for applications where improved frequency accuracy is beneficial.

Compliance and Certification: All substitute parts maintain ROHS3 compliance and EAR99 export classification, matching the regulatory status of the original part. All parts are classified under HTSUS 8541.60.0050.

Physical Compatibility: All substitute parts use HC-49/US package with identical lateral dimensions (0.453" L x 0.197" W). Seated height of substitute parts (0.138" maximum) is slightly lower than the original part (0.145" maximum), presenting no compatibility issues for standard through-hole PCB applications.

Frequently Asked Questions (FAQ)

Q: Can ABL-8.192MHZ-B1U-T be used as a direct replacement for 9B-8.192MAAJ-B? A: Yes. ABL-8.192MHZ-B1U-T is electrically and mechanically compatible. It provides tighter frequency stability (±10ppm versus ±30ppm), which is an improvement over the original specification.

Q: What is the difference between the three Abracon substitute parts? A: The three Abracon substitutes differ only in frequency stability tolerance: ABL-8.192MHZ-B1U-T (±10ppm), ABL-8.192MHZ-B2 (±20ppm), and ABL-8.192MHZ-B4Y-T (±30ppm). All other electrical and mechanical parameters are identical.

Q: Are there any physical dimension differences between the main part and substitutes? A: Lateral dimensions are identical (0.453" L x 0.197" W). The seated height of substitute parts is 0.138" maximum compared to 0.145" maximum for the original part. This minor difference does not affect through-hole PCB mounting compatibility.

Q: Do all parts meet RoHS and export compliance requirements? A: Yes. All parts listed are ROHS3 compliant and classified as EAR99 for export purposes, matching the regulatory status of the original 9B-8.192MAAJ-B.

Q: Which substitute part should be selected for new designs? A: ABL-8.192MHZ-B4Y-T is the direct equivalent with matching ±30ppm stability. For applications requiring improved frequency accuracy, ABL-8.192MHZ-B1U-T or ABL-8.192MHZ-B2 are suitable alternatives.

Q: Are these parts available in different packaging options? A: ABL-8.192MHZ-B2 is available in Bulk packaging. ABL-8.192MHZ-B1U-T and ABL-8.192MHZ-B4Y-T are available in standard packaging configurations.

Q: What is the operating temperature range for all parts? A: All parts operate across the identical temperature range of -20°C to 70°C.
