Substitute Part Grouping Explanation

Substitution eligibility for the ASE-14.31818MHZ-C-T3 is determined by strict equivalence across the following critical parameters:

• Frequency: 14.31818 MHz (exact match required)
• Output: CMOS
• Supply Voltage: 3.3V
• Function: Enable/Disable capability
• Frequency Stability: ±50ppm
• Operating Temperature: -10°C ~ 70°C
• Package: 4-SMD, No Lead with matching footprint dimensions (3.20mm x 2.50mm)
• Base Resonator: Crystal
• Type: XO (Standard)

The identified substitute part 7X-14.31818MBB-T from TXC CORPORATION meets all electrical and mechanical requirements for direct substitution. Both parts share identical frequency, output characteristics, supply voltage, enable/disable function, frequency stability, operating temperature range, and physical package specifications. Differences in maximum supply current and seated height do not affect substitution eligibility within the defined parameter set.

Parameter Comparison

Engineering Selection Recommendations

Both the ASE-14.31818MHZ-C-T3 and 7X-14.31818MBB-T are Active status products with full regulatory compliance. The Abracon part carries ROHS3 certification, while the TXC part carries standard RoHS certification. Both maintain REACH Unaffected status and Moisture Sensitivity Level 1 (Unlimited), indicating equivalent environmental and handling requirements.

Selection between these parts should be based on:

• Inventory availability and lead time requirements
• Supply chain continuity and preferred vendor relationships
• Maximum supply current tolerance (7mA vs. 20mA)
• Seated height constraints (1.20mm vs. 1.10mm)
• Packaging format preference (standard vs. Tape & Reel)

Both parts are electrically and mechanically interchangeable within the specified parameter constraints.

Frequently Asked Questions (FAQ)

Q: Can the 7X-14.31818MBB-T replace the ASE-14.31818MHZ-C-T3 in existing designs?

A: Yes. Both parts share identical frequency (14.31818 MHz), CMOS output, 3.3V supply voltage, enable/disable function, ±50ppm frequency stability, -10°C ~ 70°C operating temperature range, and 4-SMD No Lead package with 3.20mm x 2.50mm footprint. The parts are electrically and mechanically equivalent for direct substitution.

Q: What are the differences between these two parts?

A: The primary differences are maximum supply current (7mA vs. 20mA) and seated height (1.20mm vs. 1.10mm). The TXC part has higher current consumption and slightly lower profile. Both differences fall outside the critical substitution parameters and do not affect functional compatibility.

Q: Are there packaging differences?

A: The ASE part is supplied in standard packaging, while the 7X part is supplied in Tape & Reel (TR) format. Both use identical 4-SMD, No Lead package geometry. Tape & Reel packaging is standard for high-volume surface mount assembly and does not affect component performance.

Q: Do both parts meet the same regulatory requirements?

A: Both parts are RoHS compliant, REACH Unaffected, and carry Moisture Sensitivity Level 1 (Unlimited). The Abracon part carries ROHS3 certification while the TXC part carries standard RoHS certification. Both meet current environmental and regulatory standards.

Q: What is the frequency stability specification?

A: Both parts maintain ±50ppm frequency stability across the -10°C ~ 70°C operating temperature range, ensuring consistent timing performance in target applications.
