Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PCR1C680MCL1GS is determined by the following critical parameters:

• Capacitance value: 68 µF (exact match required)
• Voltage rating: 16 V (exact match required)
• Capacitor type: Aluminum polymer (exact match required)
• Tolerance: ±20% (exact match required)
• Package: Radial, Can - SMD surface mount (exact match required)
• RoHS compliance: ROHS3 Compliant (required for regulatory alignment)

The PCS1C680MCL1GS meets all substitution criteria. While it differs in ESR, lifetime rating, and ripple current specifications, these variations remain within acceptable parameters for equivalent component selection. The substitute maintains identical electrical ratings and package configuration, ensuring mechanical and electrical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The PCS1C680MCL1GS is a direct functional equivalent for the obsolete PCR1C680MCL1GS. Both components are manufactured by Nichicon and maintain ROHS3 compliance. The substitute offers improved ESR performance (30 mOhm versus 65 mOhm) and higher ripple current capability (2.2 A versus 800 mA at 100 kHz), providing enhanced electrical performance characteristics.

The primary design consideration is the dimensional difference. The substitute has a larger case diameter (6.30mm versus 5.00mm) and different land size footprint (6.60mm x 6.60mm versus 5.30mm x 5.30mm). PCB layout modifications are required to accommodate the larger package footprint. Height specifications are comparable (6.00mm versus 6.10mm), presenting no clearance concerns.

The operating temperature range of the substitute extends to 105°C maximum, compared to 125°C for the original part. Applications requiring sustained operation above 105°C require thermal analysis to confirm suitability. For general-purpose and automotive applications operating within the 105°C limit, the PCS1C680MCL1GS provides equivalent or superior performance.

Frequently Asked Questions (FAQ)

Q: Can the PCS1C680MCL1GS be used as a direct drop-in replacement?

A: Electrical substitution is valid. However, the larger package diameter and different land size require PCB layout modification. Direct PCB mounting without layout changes is not possible.

Q: What are the key differences between these two parts?

A: The substitute offers lower ESR (30 mOhm versus 65 mOhm) and higher ripple current rating (2.2 A versus 800 mA). The case diameter increases from 5.00mm to 6.30mm, and the surface mount land size increases from 5.30mm x 5.30mm to 6.60mm x 6.60mm. Operating temperature maximum decreases from 125°C to 105°C.

Q: Is the substitute suitable for automotive applications?

A: The original PCR1C680MCL1GS carries AEC-Q200 automotive certification. The substitute PCS1C680MCL1GS is rated for general-purpose applications without automotive certification listed. Application suitability depends on specific automotive qualification requirements.

Q: Are both parts RoHS compliant?

A: Yes, both the PCR1C680MCL1GS and PCS1C680MCL1GS are ROHS3 compliant.

Q: What is the impact of the larger package size?

A: The substitute requires a larger footprint on the PCB. Existing PCB designs must be modified to accommodate the 6.30mm diameter case and 6.60mm x 6.60mm land size. Height clearance is not a concern, as both parts are comparable in seated height.
