LDC500001 Equivalent & Substitute Parts

Part Overview

The LDC500001 is a 125 MHz XO (Standard) LVDS Oscillator manufactured by Diodes Incorporated, designed for applications requiring precision frequency generation with enable/disable functionality. This surface mount device operates at 3.3V supply voltage with ±50ppm frequency stability across the -40°C to 85°C temperature range. The part is currently active in production with 1114 units in stock. Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are required for procurement flexibility, inventory management, or supply chain continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the LDC500001 are qualified based on the following critical parameters that must match or remain compatible:

• Frequency: 125 MHz (exact match required)
• Output Configuration: LVDS (exact match required)
• Supply Voltage: 3.3V (exact match required)
• Frequency Stability: ±50ppm (exact match required)
• Operating Temperature Range: -40°C ~ 85°C (exact match required)
• Enable/Disable Function: Present (exact match required)
• Package Type: 6-SMD, No Lead (exact match required)
• Physical Footprint: 5.00mm x 3.20mm (exact match required)
• Regulatory Compliance: ROHS3 Compliant, REACH Unaffected (exact match required)

The SXO53L3A481-125.000M from Suntsu Electronics, Inc. qualifies as a direct substitute based on matching all critical electrical and mechanical parameters. Variations in maximum supply current (47mA vs. 60mA) and seated height (1.30mm vs. 1.20mm) remain within acceptable tolerance ranges for this product category and do not affect functional compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the LDC500001 and SXO53L3A481-125.000M are active production parts with full ROHS3 compliance and REACH unaffected status, making them suitable for applications with regulatory requirements. Selection between these parts should be based on:

• Availability and lead time requirements
• Packaging preferences (Diodes Incorporated offers standard packaging; Suntsu provides bulk packaging)
• Supply chain strategy and preferred vendor relationships
• Current inventory levels (LDC500001: 1114 units; SXO53L3A481-125.000M: 1795 units)

The SXO53L3A481-125.000M demonstrates lower maximum seated height (1.20mm vs. 1.30mm) and higher maximum supply current rating (60mA vs. 47mA), both of which provide additional design margin in space-constrained or high-current applications.

Frequently Asked Questions (FAQ)

Q: Can the SXO53L3A481-125.000M be used as a direct replacement for the LDC500001 without PCB modifications?

A: Yes. Both parts share identical electrical specifications (125 MHz, LVDS output, 3.3V supply, ±50ppm stability, enable/disable function) and identical physical footprints (5.00mm x 3.20mm, 6-SMD No Lead package). The 0.10mm difference in seated height is within standard PCB assembly tolerances and does not require design changes.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution eligibility is determined by exact matching of: frequency (125 MHz), output type (LVDS), supply voltage (3.3V), frequency stability (±50ppm), operating temperature range (-40°C to 85°C), enable/disable function presence, package type (6-SMD No Lead), physical footprint (5.00mm x 3.20mm), and regulatory compliance status (ROHS3, REACH).

Q: Are there differences in supply current specifications between these parts?

A: The LDC500001 specifies maximum supply current of 47mA, while the SXO53L3A481-125.000M specifies 60mA. Both values are within acceptable operating ranges for 125 MHz LVDS oscillators. The higher rating on the Suntsu part provides additional current margin but does not affect compatibility.

Q: What packaging options are available for each part?

A: The LDC500001 is available in standard packaging, while the SXO53L3A481-125.000M is supplied in bulk packaging. Both use identical 6-SMD No Lead surface mount packages suitable for automated assembly processes.

Q: Are both parts compliant with current regulatory standards?

A: Yes. Both the LDC500001 and SXO53L3A481-125.000M are ROHS3 compliant and REACH unaffected, meeting current environmental and hazardous substance regulations for electronic components.
