Substitute Part Grouping Explanation

Substitute parts for the LXY35VB10RM5X5LL are classified into two categories based on electrical and mechanical compatibility:

Direct Substitutes (Identical Electrical Specifications): Parts that maintain the same capacitance (10 µF), voltage rating (35 V), tolerance (±20%), and mounting configuration (through-hole radial, can package) are classified as direct substitutes. These parts satisfy the core electrical requirements and physical footprint constraints of the original design.

Similar Substitutes (Equivalent Electrical Performance): Parts that maintain capacitance, voltage rating, tolerance, and mounting type but may differ in physical dimensions, thermal lifetime, or ripple current ratings are classified as similar substitutes. These parts are electrically compatible but require verification of board layout constraints due to dimensional differences.

The following parameters determine substitution eligibility:

Capacitance: 10 µF (fixed requirement)
Voltage Rating: 35 V (fixed requirement)
Tolerance: ±20% (fixed requirement)
Polarization: Polar (fixed requirement)
Mounting Type: Through Hole (fixed requirement)
Package Type: Radial, Can (fixed requirement)
Lead Spacing: 0.079" (2.00 mm) (fixed requirement)

Engineering Selection Recommendations

For New Designs and Active Production:

The Würth Elektronik 860020572003 is the recommended substitute for new designs and active production applications. This part maintains identical electrical specifications (10 µF, 35 V, ±20% tolerance) and physical footprint (0.079" lead spacing, 0.197" diameter) as the original LXY35VB10RM5X5LL. The 860020572003 is currently active in production, ROHS3 compliant, and available in high inventory quantities (7834 pcs). The increased seated height (0.492" vs. 0.197") requires board layout verification but does not affect electrical compatibility.

For Legacy System Maintenance:

The Nichicon UPW1V100MDD provides electrical equivalence for field service and legacy system support. This part matches the original capacitance, voltage rating, tolerance, and thermal lifetime specifications. However, the UPW1V100MDD is classified as obsolete and has higher impedance (600 mOhms vs. 120 mOhms) and lower ripple current ratings compared to the original part. The increased seated height (0.433" vs. 0.197") requires board layout verification. This part is suitable only for direct replacement in existing assemblies where inventory is available.

Compliance Considerations:

The original LXY35VB10RM5X5LL is RoHS non-compliant. The Würth Elektronik 860020572003 is ROHS3 compliant and is the preferred choice for applications requiring regulatory compliance. The Nichicon UPW1V100MDD is also ROHS3 compliant but is obsolete.

Frequently Asked Questions (FAQ)

Q: Can the Würth Elektronik 860020572003 be used as a direct replacement for the LXY35VB10RM5X5LL?

A: Yes, the 860020572003 is electrically equivalent. Both parts have identical capacitance (10 µF), voltage rating (35 V), tolerance (±20%), and lead spacing (0.079" / 2.00 mm). The primary difference is the seated height: the 860020572003 measures 0.492" (12.50 mm) compared to 0.197" (5.00 mm) for the original part. Board layout verification is required to confirm clearance for the taller component.

Q: What is the difference between the LXY35VB10RM5X5LL and the Nichicon UPW1V100MDD?

A: Both parts share identical capacitance (10 µF), voltage rating (35 V), tolerance (±20%), and thermal lifetime (2000 Hrs @ 105°C). The UPW1V100MDD has higher impedance (600 mOhms vs. 120 mOhms) and lower ripple current ratings. The seated height is 0.433" (11.00 mm) compared to 0.197" (5.00 mm). The UPW1V100MDD is obsolete and should be used only for legacy system maintenance.

Q: Why is the Würth Elektronik 860020572003 recommended over the Nichicon UPW1V100MDD?

A: The 860020572003 is currently active in production with high inventory availability (7834 pcs), while the UPW1V100MDD is obsolete. The 860020572003 is ROHS3 compliant and has lower impedance (120 mOhms), providing better electrical performance for new designs and active production applications.

Q: Are there any temperature range differences between the substitute parts?

A: The LXY35VB10RM5X5LL and Nichicon UPW1V100MDD both operate from -55°C to 105°C. The Würth Elektronik 860020572003 operates from -40°C to 105°C, which is a narrower range at the lower temperature limit. For applications requiring operation below -40°C, the original part or the Nichicon part must be used.

Q: What is the impact of the different ripple current ratings?

A: The LXY35VB10RM5X5LL has ripple current ratings of 250 mA @ 120 Hz and 625 mA @ 100 kHz. The Würth Elektronik 860020572003 has lower ratings (46 mA @ 120 Hz and 78.2 mA @ 100 kHz), while the Nichicon UPW1V100MDD has intermediate ratings (54 mA @ 120 Hz and 180 mA @ 100 kHz). Applications with high ripple current requirements must verify that the substitute part meets the circuit's ripple current specifications.

Q: Can the ELXY350ELL121MJC5S be used as a substitute?

A: No. The ELXY350ELL121MJC5S has a capacitance of 120 µF, which differs from the required 10 µF. Although it shares the same voltage rating (35 V) and tolerance (±20%), the different capacitance value makes it unsuitable as a direct substitute. This part is listed as a cross-reference but does not meet the electrical requirements of the original design.
