Parameter Comparison

Engineering Selection Recommendations

Substitution Feasibility:

The ELXY350ELL270MEB5D is electrically compatible with the LXY35VB22RM6X5LL based on matching voltage rating, operating temperature range, lifetime specification, and ripple current capabilities. Both components are aluminum electrolytic capacitors in radial can packages with identical impedance and tolerance specifications.

Key Considerations:

1. Capacitance Variance: The substitute part provides 27 µF compared to the original 22 µF specification. This 5 µF increase (22.7% higher) remains within the ±20% tolerance band of the original part. Circuit design must verify that increased capacitance does not adversely affect frequency response, timing characteristics, or voltage regulation performance in the target application.

2. Physical Dimensions: The substitute exhibits reduced diameter (5.00mm versus 6.30mm) but increased height (13.00mm versus 5.00mm). PCB layout must accommodate the taller profile. Lead spacing differs (2.00mm versus 2.50mm), requiring footprint verification or minor PCB redesign.

3. Product Status and Compliance: The substitute is Active status with ROHS3 compliance and AEC-Q200 automotive qualification, ensuring current manufacturing availability and regulatory acceptability. The original part is Obsolete and RoHS non-compliant, making the substitute the preferred choice for new designs or ongoing production.

4. Inventory and Availability: The substitute maintains significantly higher inventory (3719 Pcs) compared to the original part (688 Pcs), supporting supply chain continuity.

Selection Criteria:

• Select ELXY350ELL270MEB5D when circuit design permits 27 µF capacitance and vertical clearance accommodates 13.00mm height
• Verify PCB footprint compatibility with 2.00mm lead spacing
• Confirm that increased capacitance does not degrade circuit performance in filtering, timing, or voltage regulation functions
• Prioritize the substitute for new designs due to Active status and regulatory compliance

Frequently Asked Questions (FAQ)

Q1: Can the ELXY350ELL270MEB5D directly replace the LXY35VB22RM6X5LL without circuit modification?

A: Electrical substitution is feasible based on voltage rating, temperature range, and ripple current specifications. However, physical dimensions differ significantly. Lead spacing changes from 2.50mm to 2.00mm, and height increases from 5.00mm to 13.00mm. PCB layout verification is mandatory. Additionally, the 5 µF capacitance increase must be evaluated within the circuit design to ensure no adverse effects on frequency response or system performance.

Q2: Why does the substitute part have higher capacitance (27 µF versus 22 µF)?

A: The substitute is selected from the same LXY series with identical electrical ratings (voltage, temperature, lifetime, ripple current, impedance). The capacitance difference reflects the available product range within Chemi-Con's portfolio. The 27 µF value remains within acceptable substitution parameters when the application circuit design permits higher capacitance values without performance degradation.

Q3: What is the significance of the lead spacing difference (2.50mm versus 2.00mm)?

A: Lead spacing determines PCB footprint compatibility. The original part uses 2.50mm spacing; the substitute uses 2.00mm spacing. Existing PCB designs with 2.50mm hole patterns require modification to accommodate the substitute. This may involve drilling new holes or using adapter techniques. New PCB designs should incorporate 2.00mm spacing to utilize the substitute part.

Q4: How does the height difference (5.00mm versus 13.00mm) affect board assembly?

A: The substitute is significantly taller (13.00mm versus 5.00mm). PCB designs must verify vertical clearance above the component to prevent interference with other components, shielding, or enclosure constraints. The increased height may require layout modifications or component repositioning. Height verification is essential before committing to the substitute in existing designs.

Q5: What does "Obsolete" status mean for the original part, and why is "Active" status important for the substitute?

A: Obsolete status indicates the LXY35VB22RM6X5LL is no longer manufactured by Chemi-Con. Existing inventory may be available from distributors, but long-term sourcing is not guaranteed. Active status for the ELXY350ELL270MEB5D confirms current manufacturing and reliable supply chain availability. For ongoing production or new designs, Active status components are strongly preferred.

Q6: What is the impact of RoHS3 compliance on the substitute part?

A: RoHS3 compliance indicates the ELXY350ELL270MEB5D meets current environmental regulations restricting hazardous substances in electrical and electronic equipment. The original part is RoHS non-compliant, reflecting its obsolete status and older manufacturing standards. For applications subject to regulatory requirements or customer specifications mandating RoHS compliance, the substitute is the appropriate choice.

Q7: Does AEC-Q200 automotive qualification on the substitute affect its use in non-automotive applications?

A: AEC-Q200 is an automotive industry qualification standard indicating enhanced reliability testing and quality assurance. This certification does not restrict use in non-automotive applications; rather, it demonstrates superior reliability and quality control. Non-automotive applications benefit from the enhanced qualification without any negative consequences.

Q8: How should I verify that the 27 µF capacitance is acceptable in my circuit?

A: Evaluate the circuit's functional requirements for capacitance value. Determine whether the circuit is capacitance-sensitive (e.g., timing circuits, frequency-dependent filters) or capacitance-tolerant (e.g., power supply filtering, general decoupling). For capacitance-sensitive circuits, perform circuit simulation or analysis with 27 µF to confirm acceptable performance. For capacitance-tolerant applications, the 5 µF increase typically poses no risk. Consult circuit design documentation or perform empirical testing if uncertainty exists.

Q9: Are there any other substitute parts available for the LXY35VB22RM6X5LL?

A: Based on the provided input parameters, ELXY350ELL270MEB5D is the identified substitute. The substitute part itself lists additional alternatives (EEU-FC1V270, UPM1V270MDD, UPW1V270MDD), indicating a broader ecosystem of compatible components. However, evaluation of those alternatives requires their detailed specifications and is outside the scope of this reference.

Q10: What should I do if the physical dimensions of the substitute are incompatible with my PCB design?

A: If the substitute's dimensions cannot be accommodated, evaluate whether other capacitors from the LXY series or alternative manufacturers offer compatible physical profiles while maintaining the required electrical specifications (35 V, 2000 Hrs @ 105°C, ripple current ratings). Consult with component suppliers or manufacturers for alternatives matching your specific dimensional constraints. PCB redesign may also be considered if the substitute's superior compliance and availability justify the engineering effort.
