Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the V802-074.25M is determined by the following critical parameters:

• Frequency Match: 74.25 MHz (exact match required)
• Output Compatibility: LVCMOS (required for signal integrity)
• Supply Voltage: 3.3V (required for circuit compatibility)
• Package Type: 6-SMD, No Lead (required for PCB footprint compatibility)
• Physical Dimensions: 7.00mm x 5.00mm x 1.80mm (required for mechanical fit)
• Function: Enable/Disable capability (required for operational compatibility)

The V803-074.25M qualifies as a direct substitute because it matches all critical parameters. Differences in frequency stability (±15ppm vs. ±50ppm) and supply current (30mA vs. 40mA) represent improvements over the original part and do not prevent substitution. The V803 series is active and available, addressing the obsolescence of the V802 series.

Parameter Comparison

Engineering Selection Recommendations

The V803-074.25M is the direct substitute for the V802-074.25M based on the following engineering criteria:

Product Status: The V803-074.25M is active and currently in production, whereas the V802-074.25M is obsolete. This ensures long-term supply chain availability and support.

Compliance & Certifications: The V803-074.25M carries ROHS3 compliance certification, meeting current regulatory requirements. Both parts maintain REACH Unaffected status and EAR99 ECCN classification.

Electrical Compatibility: All critical electrical parameters match exactly: 74.25 MHz frequency, LVCMOS output, 3.3V supply, ±50ppm APR, and 0°C to 70°C operating range. The improved frequency stability (±15ppm) and reduced supply current (30mA) of the V803 series provide performance benefits without introducing compatibility issues.

Mechanical Compatibility: Identical package type, physical dimensions, and MSL rating ensure direct PCB footprint compatibility and identical handling requirements.

Frequently Asked Questions (FAQ)

Q: Can the V803-074.25M be used as a direct replacement for the V802-074.25M without PCB modifications?

A: Yes. Both parts share identical package type (6-SMD, No Lead), physical dimensions (7.00mm x 5.00mm x 1.80mm), and pin configuration. No PCB layout changes are required.

Q: What are the key differences between the V802 and V803 series?

A: The V803-074.25M offers improved frequency stability (±15ppm vs. ±50ppm) and lower supply current (30mA vs. 40mA). The V803 series is active and ROHS3 compliant, whereas the V802 is obsolete. All functional and electrical parameters remain compatible.

Q: Are there any thermal or operating condition limitations when substituting the V803 for the V802?

A: No. Both parts operate across the identical temperature range (0°C to 70°C) and maintain the same MSL rating (1 - Unlimited). Thermal performance is equivalent.

Q: Does the improved frequency stability of the V803 affect circuit design or require recalibration?

A: No. The V803's tighter frequency stability (±15ppm) is a performance improvement that does not require design changes. Systems designed for the V802's ±50ppm specification will operate within acceptable parameters with the V803.

Q: What is the packaging difference between the V802 and V803?

A: The V802-074.25M is supplied in standard packaging, while the V803-074.25M is supplied in strip packaging. Both use identical 6-SMD, No Lead packages. Strip packaging is standard for active production parts and does not affect component functionality or compatibility.

Q: Are both parts RoHS compliant?

A: The V803-074.25M is ROHS3 compliant. The V802-074.25M RoHS status is not specified in available documentation. The V803 is the recommended choice for applications requiring documented RoHS compliance.
