Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the LDF000002 are qualified based on strict electrical and mechanical parameter matching. The following criteria determine substitution eligibility:

• Identical frequency specification (150 MHz)
• Matching output type (LVDS)
• Identical supply voltage (3.3V)
• Matching function capability (Enable/Disable)
• Identical frequency stability (±50ppm)
• Overlapping or identical operating temperature range (-20°C ~ 70°C)
• Identical package type (6-SMD, No Lead)
• Compatible physical dimensions (5.00mm x 3.20mm)
• Surface Mount mounting compatibility
• RoHS3 compliance certification

The SXO53L3A271-150.000M from Suntsu Electronics, Inc. meets all substitution criteria and is classified as a direct equivalent.

Parameter Comparison

Engineering Selection Recommendations

Both the LDF000002 and SXO53L3A271-150.000M are active products with full RoHS3 compliance and REACH unaffected status. Selection between these parts should be based on:

• Supply chain availability and lead time requirements
• Inventory levels at component distributors
• Packaging format preference (Diodes Inc. offers tape/reel; Suntsu offers bulk)
• PCB layout constraints (Suntsu part has lower seated height of 1.20mm vs. 1.30mm)
• Power budget considerations (Suntsu part rated for 60mA maximum supply current vs. 47mA for Diodes Inc.)

Both parts are electrically and mechanically interchangeable for 150 MHz LVDS oscillator applications operating at 3.3V with Enable/Disable control.

Frequently Asked Questions (FAQ)

Q: Can the SXO53L3A271-150.000M directly replace the LDF000002 on existing PCBs?

A: Yes. Both parts share identical package type (6-SMD, No Lead), physical dimensions (5.00mm x 3.20mm), and pinout configuration. The Suntsu part has a lower seated height (1.20mm vs. 1.30mm), which provides additional PCB clearance margin.

Q: Are there differences in frequency stability between these parts?

A: No. Both parts specify ±50ppm frequency stability across the operating temperature range of -20°C to 70°C.

Q: What is the significance of the different maximum supply current ratings?

A: The LDF000002 is rated for 47mA maximum supply current, while the SXO53L3A271-150.000M is rated for 60mA. The Suntsu part has a higher current rating, making it suitable for applications with less stringent power constraints. Both parts will operate correctly in circuits designed for the lower current specification.

Q: Do both parts support Enable/Disable functionality?

A: Yes. Both the LDF000002 and SXO53L3A271-150.000M include Enable/Disable control functionality for power management applications.

Q: Are both parts RoHS3 compliant?

A: Yes. Both parts are certified RoHS3 compliant and REACH unaffected, meeting environmental and regulatory requirements for commercial and industrial applications.

Q: What packaging options are available?

A: The LDF000002 is available in tape/reel packaging, while the SXO53L3A271-150.000M is supplied in bulk packaging. Packaging selection depends on production volume and assembly process requirements.
