A: Yes. SLPX682M035E1P3 matches all critical parameters: 6800 µF capacitance, 35 V voltage rating, ±20% tolerance, radial snap-in package, and 10.00 mm lead spacing. The substitute provides improved reliability with 3000-hour lifetime at 85°C compared to the original 1000-hour specification. Physical dimensions differ slightly (25.00 mm height versus 30.00 mm), requiring verification of PCB clearance.

Q: What is the difference between SLPX682M035E1P3 and SLP682M035E1P3?

A: Both parts share identical electrical specifications (6800 µF, 35 V, ±20%, 78 mOhm ESR, 3000-hour lifetime). The primary difference is operating temperature range: SLPX682M035E1P3 operates -40°C to 85°C, while SLP682M035E1P3 extends to -40°C to 105°C. Select SLP682M035E1P3 for applications requiring higher temperature performance.

Q: Are the physical dimensions of substitute parts critical for PCB compatibility?

A: Yes. While all substitutes maintain the 10.00 mm lead spacing required for PCB footprint compatibility, diameter and height vary. The original LPW682M1VP30V-W measures 30.00 mm diameter by 30.00 mm height. Substitutes range from 22.00 mm to 35.00 mm diameter and 22.00 mm to 40.00 mm height. Verify PCB layout clearance before selecting a substitute with different dimensions.

Q: Can I use 688LBB035M2DC as a substitute despite the different manufacturer?

A: Yes. 688LBB035M2DC is manufactured by Cornell Dubilier / Illinois Capacitor and meets all critical electrical and mechanical specifications. It provides superior ESR performance (60.95 mOhm versus 85 mOhm) with identical 30.00 mm diameter and 27.00 mm height. Verify manufacturer qualification requirements for your application.

Q: What does the ESR difference mean for circuit performance?

A: ESR (Equivalent Series Resistance) affects ripple current handling and voltage regulation. Lower ESR values indicate better high-frequency performance and reduced heat generation. Substitutes with lower ESR (69-70.95 mOhm) provide improved performance compared to the original 85 mOhm specification. This is beneficial for applications with high ripple current requirements.

Q: Is the 3000-hour lifetime improvement significant compared to the original 1000-hour specification?

A: Yes. The 3x improvement in lifetime at 85°C indicates enhanced reliability and extended service life. All active substitute parts provide 3000-hour lifetime, making them suitable for long-term production applications. This improvement reduces field failure risk and supports extended product lifecycle requirements.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed maintain RoHS3 compliance and REACH unaffected status, matching the original LPW682M1VP30V-W regulatory requirements. This ensures compatibility with environmental and regulatory standards across all markets.

Q: Which substitute offers the best overall performance?

A: SLPX682M035E1P3 provides the optimal balance of direct compatibility, improved reliability, and active product status. It maintains the original operating temperature range (-40°C to 85°C) with 3x improved lifetime (3000 hours) and reduced ESR (78 mOhm). For applications requiring extended temperature operation, SLP682M035E1P3 is recommended. For superior ESR performance, 688LBB035M2DC is the preferred choice.
