Key Parameters

Substitute Part Grouping Explanation

Substitution of the TC-22.5792MBD-T is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Frequency: 22.5792 MHz (exact match required)
• Output Type: CMOS
• Supply Voltage: 3.3V
• Function: Enable/Disable capability
• Frequency Stability: ±25ppm
• Operating Temperature Range: -40°C ~ 85°C
• Package Type: 4-SMD, No Lead
• Package Dimensions: 3.20mm × 2.50mm
• Mounting Type: Surface Mount

The substitute part 7X-22.5792MBD-T meets all mandatory matching parameters. The primary difference between the main part and substitute is the base resonator technology (MEMS versus Crystal) and current supply specifications, which do not affect functional compatibility within the defined electrical and mechanical constraints.

Engineering Selection Recommendations

7X-22.5792MBD-T as Primary Substitute:

The 7X-22.5792MBD-T is the direct equivalent substitute for the obsolete TC-22.5792MBD-T. Selection of this substitute is supported by the following factors:

1. Product Status: The 7X-22.5792MBD-T maintains Active status, ensuring ongoing availability and supply chain continuity.

2. Electrical Equivalence: All critical electrical parameters match the original specification: 22.5792 MHz frequency, 3.3V supply, CMOS output, Enable/Disable function, ±25ppm stability, and -40°C ~ 85°C operating range.

3. Mechanical Compatibility: Package type, dimensions (3.20mm × 2.50mm), and surface mount configuration are identical, enabling direct PCB layout compatibility.

4. Compliance Certifications: The substitute carries RoHS Compliance and REACH Unaffected status, meeting current regulatory requirements.

5. Current Supply Differential: The substitute operates at 15mA maximum supply current versus 25mA for the original. This represents a reduction in power consumption and does not create compatibility issues in applications designed for the original specification.

6. Height Consideration: The substitute seated height is 1.10mm compared to 0.80mm for the original. Verification of PCB clearance in height-constrained applications is required.

7. Packaging Format: The substitute is supplied in Tape & Reel format, standard for production environments, versus bulk packaging for the original.

Frequently Asked Questions (FAQ)

Q1: Can the 7X-22.5792MBD-T be used as a direct replacement for the TC-22.5792MBD-T?

A: Yes. The 7X-22.5792MBD-T meets all mandatory electrical and mechanical parameters required for functional equivalence. Identical frequency, output type, supply voltage, function, stability, temperature range, package type, and dimensions enable direct substitution in circuit designs.

Q2: What is the difference between MEMS and Crystal base resonators in these oscillators?

A: The TC-22.5792MBD-T uses MEMS technology while the 7X-22.5792MBD-T uses Crystal technology. Both deliver the same electrical performance within the specified ±25ppm stability. The resonator technology difference does not affect functional compatibility when electrical specifications are matched.

Q3: Does the lower current consumption of the 7X-22.5792MBD-T (15mA vs. 25mA) affect circuit design?

A: No. The substitute's lower maximum supply current is a performance advantage. Circuits designed for the original 25mA specification will operate correctly with the 15mA substitute. Power supply and decoupling design based on the original specification remains valid.

Q4: Is the increased height of the 7X-22.5792MBD-T (1.10mm vs. 0.80mm) a concern?

A: Height difference must be evaluated in the context of specific PCB layout and enclosure constraints. The 0.30mm increase may be significant in height-limited applications. Verify clearance in your mechanical design before implementation.

Q5: What compliance advantages does the 7X-22.5792MBD-T provide?

A: The substitute carries RoHS Compliance and REACH Unaffected certifications. These regulatory certifications support compliance requirements in markets with environmental and hazardous substance restrictions.

Q6: Are there packaging considerations when transitioning from TC to 7X series?

A: The original TC-22.5792MBD-T is supplied in bulk packaging. The 7X-22.5792MBD-T is supplied in Tape & Reel format. Tape & Reel packaging is standard for automated assembly processes and provides improved component protection and handling efficiency in production environments.

Q7: What is the inventory status of these parts?

A: The TC-22.5792MBD-T (Obsolete) has 1114 pieces in stock. The 7X-22.5792MBD-T (Active) has 985 pieces in stock. Active product status ensures continued availability for future procurement.
