Key Parameters

Substitute Part Grouping Explanation

Substitution of the LDF620006 is determined by strict equivalence across the following critical parameters:

• Frequency: Exact match at 156.25 MHz
• Output Signaling: LVDS output required
• Supply Voltage: 3.3V operation
• Enable/Disable Function: Control capability must be present
• Frequency Stability: ±50ppm tolerance
• Operating Temperature: -20°C ~ 70°C range
• Package Configuration: 6-SMD, No Lead form factor
• Physical Dimensions: 5.00mm x 3.20mm footprint
• Compliance: ROHS3 Compliant, EAR99 classification

The SXO53L3A271-156.250M from Suntsu Electronics meets all specified parameters and qualifies as a direct substitute.

Parameter Comparison

Engineering Selection Recommendations

Both the LDF620006 and SXO53L3A271-156.250M are active products with identical core electrical specifications and ROHS3 compliance. Selection between these parts should be based on:

• Supply Chain Availability: The SXO53L3A271-156.250M currently has higher inventory (3313 Pcs vs. 675 Pcs).
• Current Consumption: The LDF620006 operates at 47mA maximum supply current, while the SXO53L3A271-156.250M draws up to 60mA. Applications with strict power budgets should account for this 13mA difference.
• Mounted Height: The SXO53L3A271-156.250M has a lower seated height (1.20mm vs. 1.30mm), which may be advantageous in space-constrained designs.
• Regulatory Compliance: Both parts maintain EAR99 classification and ROHS3 compliance, suitable for equivalent procurement decisions.

Frequently Asked Questions (FAQ)

Q: Can the SXO53L3A271-156.250M directly replace the LDF620006 on existing PCBs?

A: Yes. Both parts share identical package dimensions (5.00mm x 3.20mm), 6-SMD No Lead configuration, and pinout compatibility for LVDS output with Enable/Disable control at 3.3V. The mounted height difference (1.20mm vs. 1.30mm) is within typical PCB assembly tolerances.

Q: What is the impact of the 13mA current difference between these parts?

A: The SXO53L3A271-156.250M has a maximum supply current of 60mA compared to 47mA for the LDF620006. In applications where power consumption is critical, this 13mA increase should be evaluated against the power supply capacity and thermal design of the system.

Q: Are both parts suitable for the same operating temperature range?

A: Yes. Both the LDF620006 and SXO53L3A271-156.250M operate across -20°C to 70°C with identical ±50ppm frequency stability, ensuring equivalent performance across the specified temperature range.

Q: What compliance certifications apply to both substitute parts?

A: Both parts are ROHS3 Compliant, REACH Unaffected, and classified as EAR99 for export control purposes. They meet equivalent regulatory requirements for industrial and telecommunications applications.

Q: Is there a difference in disable mode current consumption?

A: The LDF620006 specifies 30µA maximum current in disable mode. The SXO53L3A271-156.250M does not provide a disable mode current specification in the available data. This parameter should be verified with the manufacturer if disable mode power consumption is a design requirement.
