Key Parameters

Substitute Part Grouping Explanation

Substitution of the LXY35VB4R7M4X5LL is determined by the following critical parameters:

Electrical Compatibility Requirements:

• Capacitance value: 4.7 µF (primary functional parameter)
• Voltage rating: 35 V (minimum required rating)
• Tolerance: ±20% (acceptable variation range)
• Operating temperature range: -55°C ~ 105°C (environmental limits)
• Lifetime rating: 2000 Hrs @ 105°C (reliability specification)

Mechanical Compatibility Requirements:

• Mounting type: Through Hole (PCB assembly method)
• Package type: Radial, Can (physical form factor)
• Polarization: Polar (electrical orientation requirement)

The substitute part ELXY350ELL560MFB5D differs in capacitance value (56 µF versus 4.7 µF). This part is listed in the provided substitute data but does not meet the strict electrical compatibility criteria for direct substitution due to the significant capacitance difference. Direct substitutes maintaining the 4.7 µF capacitance specification are not provided in the available substitute list.

Parameter Comparison

Engineering Selection Recommendations

The LXY35VB4R7M4X5LL is classified as obsolete, requiring component replacement for new designs or production continuity. The listed substitute ELXY350ELL560MFB5D offers several advantages:

Compliance and Availability:

• Active product status ensures ongoing availability and supply chain stability
• ROHS3 compliance meets current environmental and regulatory requirements
• AEC-Q200 automotive qualification provides additional reliability assurance

Electrical and Mechanical Alignment:

• Identical voltage rating (35 V) and tolerance (±20%)
• Matching operating temperature range (-55°C ~ 105°C)
• Equivalent lifetime rating (2000 Hrs @ 105°C)
• Identical ripple current specifications and impedance characteristics
• Compatible through-hole radial can package

Critical Limitation: The capacitance value differs significantly (56 µF versus 4.7 µF). This substitution is valid only in applications where the higher capacitance value is functionally acceptable or where circuit design permits capacitance adjustment. Direct one-to-one replacement in circuits requiring precisely 4.7 µF is not supported by the provided substitute data.

Frequently Asked Questions (FAQ)

Q: Can ELXY350ELL560MFB5D directly replace LXY35VB4R7M4X5LL in all applications?

A: No. While both components share identical voltage ratings, temperature ranges, and mechanical compatibility, the capacitance values differ significantly (56 µF versus 4.7 µF). Direct replacement is only valid in applications where the higher capacitance value does not adversely affect circuit performance or where design specifications permit capacitance tolerance.

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

A: Substitution eligibility is determined by: capacitance value, voltage rating, tolerance, operating temperature range, lifetime rating, mounting type, and package configuration. All parameters must align with circuit requirements and PCB assembly constraints.

Q: Why is the main part listed as obsolete?

A: The LXY35VB4R7M4X5LL is classified as obsolete by the manufacturer, indicating discontinued production. This status necessitates identification of active alternative components for ongoing production or design updates.

Q: Does ELXY350ELL560MFB5D meet modern compliance standards?

A: Yes. ELXY350ELL560MFB5D is ROHS3 compliant and carries AEC-Q200 automotive qualification, meeting current environmental and reliability standards. The main part is RoHS non-compliant, reflecting its obsolete status.

Q: Are the physical dimensions compatible between these parts?

A: Both components use through-hole radial can packages. However, physical dimensions differ: the main part measures 0.157" diameter × 0.197" height, while the substitute measures 0.248" diameter × 0.512" height. PCB layout verification is required before substitution.

Q: What is the lead spacing difference?

A: The main part does not specify lead spacing. The substitute part specifies 0.098" (2.50mm) lead spacing. PCB hole pattern compatibility must be verified during design review.
