• Frequency: 125 MHz (exact match required)
• Output Type: LVDS (exact match required)
• Supply Voltage: 3.3V (exact match required)
• Function: Enable/Disable capability (exact match required)
• Package Type: 6-SMD, No Lead (exact match required)
• Operating Temperature Range: -40°C ~ 85°C (exact match required)
• Frequency Stability: ±50ppm (exact match required)

The XUL535125.000JS6I from Renesas Electronics Corporation meets all critical substitution criteria. This part maintains identical electrical specifications and package configuration while offering active product status and improved compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The XUL535125.000JS6I is the direct substitute for the FXO-LC535R-125M. Both parts are manufactured by Renesas Electronics Corporation and maintain identical electrical and functional specifications across all critical parameters.

The XUL535125.000JS6I offers the following advantages:

• Active product status ensures ongoing availability and manufacturing support
• ROHS3 compliance and REACH Unaffected certification provide regulatory alignment with current environmental standards
• Reduced maximum supply current (97mA versus 100mA) offers improved power efficiency
• Smaller physical dimensions (5.00mm x 3.20mm versus 5.15mm x 3.35mm) and lower profile (1.20mm versus 1.40mm) provide enhanced PCB layout flexibility

The dimensional differences are within typical PCB assembly tolerances and do not impact functional compatibility or signal integrity for LVDS output applications.

Frequently Asked Questions (FAQ)

Q: Can the XUL535125.000JS6I be used as a direct replacement for the FXO-LC535R-125M?

A: Yes. Both parts operate at 125 MHz with LVDS output, 3.3V supply, enable/disable function, ±50ppm frequency stability, and -40°C to 85°C operating temperature range. The 6-SMD, No Lead package configuration is identical. The XUL535125.000JS6I is the active equivalent.

Q: Are there any physical compatibility concerns with the XUL535125.000JS6I?
