Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence across the following critical parameters:

• Frequency: 50 MHz (exact match required)
• Output Type: CMOS (exact match required)
• Supply Voltage: 3.3V (exact match required)
• Function: Enable/Disable (exact match required)
• Frequency Stability: ±50ppm (exact match required)
• Operating Temperature Range: -40°C ~ 85°C (exact match required)
• Package / Case: 4-SMD, No Lead (exact match required)
• Mounting Type: Surface Mount (exact match required)
• Size / Dimension: 0.276" L x 0.197" W (7.00mm x 5.00mm) (exact match required)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)

All five substitute parts meet these criteria and are therefore electrically and mechanically interchangeable with the 7W50002033.

Parameter Comparison

Engineering Selection Recommendations

All five substitute parts are electrically and mechanically equivalent to the 7W50002033 based on the critical parameters that determine interchangeability. Selection among these alternatives should be based on the following factors:

Product Status: All substitute parts carry active product status, ensuring long-term availability and manufacturing support compared to the obsolete 7W50002033.

Compliance Certifications: The Raltron CO4305-50.000-EXT-T-TR, Cardinal CPPC7L-A7BP-50.0TS, Cardinal CPPC7LT-A7BP-50.0TS, and Cardinal CPPLC7L-A7BP-50.0TS, and Suntsu SXO75C3A481-50.000M all carry ROHS3 compliance. The Skyworks 510CAA50M0000AAGR does not specify RoHS status in the provided data.

Physical Height Considerations: The 7W50002033 has a maximum seated height of 0.056" (1.42mm), which is lower than all substitute parts. The Suntsu SXO75C3A481-50.000M offers the closest height match at 0.063" (1.60mm), followed by the Skyworks and Raltron options at 0.071" (1.80mm), and the Cardinal variants at 0.075" (1.90mm). PCB layout clearance must be evaluated for applications with height constraints.

Current Supply Specifications: The Skyworks part specifies 26mA maximum supply current, while all other substitutes specify 25mA. This difference is negligible for most applications.

Packaging Availability: The Suntsu SXO75C3A481-50.000M is available in bulk packaging with the highest inventory (4079 pcs), while all other substitutes are supplied in tape and reel format.

Frequently Asked Questions (FAQ)

Q: Are all listed parts direct pin-for-pin replacements for the 7W50002033?

A: Yes. All substitute parts are electrically and mechanically equivalent across all critical parameters: 50 MHz frequency, CMOS output, 3.3V supply, enable/disable function, ±50ppm frequency stability, -40°C to 85°C operating range, 4-SMD no-lead package, and 7.00mm x 5.00mm footprint. They are suitable for direct PCB substitution.

Q: What is the significance of the height difference between the 7W50002033 and the substitute parts?

A: The 7W50002033 has a maximum seated height of 1.42mm, while substitute parts range from 1.60mm to 1.90mm. For applications with tight vertical clearance constraints, the Suntsu SXO75C3A481-50.000M (1.60mm) offers the closest match. PCB layout and enclosure design must be evaluated to confirm compatibility.

Q: Why is the 7W50002033 classified as obsolete?

A: The 7W50002033 is marked as obsolete by the manufacturer, indicating it is no longer in active production. The substitute parts listed are all active products from alternative manufacturers, ensuring continued availability for new designs and ongoing production support.

Q: Does the difference in current supply specifications affect circuit design?

A: The maximum supply current difference between the Skyworks part (26mA) and other substitutes (25mA) is minimal and does not require circuit redesign. Power supply and decoupling capacitor sizing should accommodate the highest specified current (26mA) for conservative design practice.

Q: What packaging formats are available for these substitute parts?

A: The Suntsu SXO75C3A481-50.000M is supplied in bulk packaging. The Skyworks, Raltron, and Cardinal parts are supplied in tape and reel (TR) format. Packaging selection depends on production volume and assembly process requirements.

Q: Are all substitute parts RoHS compliant?

A: Four of the five substitute parts carry ROHS3 compliance: Raltron CO4305-50.000-EXT-T-TR, Cardinal CPPC7L-A7BP-50.0TS, Cardinal CPPC7LT-A7BP-50.0TS, and Cardinal CPPLC7L-A7BP-50.0TS, and Suntsu SXO75C3A481-50.000M. The Skyworks 510CAA50M0000AAGR does not specify RoHS status in the provided data. For applications requiring RoHS compliance, the other four options are confirmed compliant.
