Substitute Part Grouping Explanation

Substitution of the PCX1D680MCS1GS is permissible with parts that maintain identical specifications across all critical electrical and mechanical parameters. The substitution logic is based on the following key parameters:

Electrical Parameters: Capacitance value (68 µF), voltage rating (20 V), ESR (34 mOhm), tolerance (±20%), lifetime rating (1500 Hrs @ 125°C), and ripple current capability (1.45 A @ 100 kHz) must remain unchanged.

Mechanical Parameters: Package type (Radial, Can - SMD), mounting type (Surface Mount), physical dimensions (0.248" diameter, 0.319" height), and surface mount land size (0.260" L x 0.260" W) must be identical.

Compliance Parameters: RoHS3 compliance and REACH affected status must be maintained.

Parts meeting these criteria are classified as parametric equivalents and are directly interchangeable in circuit design and PCB assembly without modification.

The PCX1D680MCL1GS is a direct parametric equivalent suitable for immediate substitution in any application currently using the PCX1D680MCS1GS.

Frequently Asked Questions (FAQ)

Q: Can the PCX1D680MCL1GS replace the PCX1D680MCS1GS in my design?

A: Yes. The PCX1D680MCL1GS is a parametric equivalent with identical capacitance (68 µF), voltage rating (20 V), ESR (34 mOhm), tolerance (±20%), lifetime rating (1500 Hrs @ 125°C), and physical dimensions. Direct substitution is permissible without circuit modification.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both parts share identical package dimensions: 0.248" diameter (6.30 mm), 0.319" maximum seated height (8.10 mm), and surface mount land size of 0.260" L x 0.260" W (6.60 mm x 6.60 mm). PCB layout and assembly tooling require no adjustment.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the PCX1D680MCS1GS and PCX1D680MCL1GS are ROHS3 compliant and REACH affected, meeting current regulatory requirements for electronic component manufacturing and use.

Q: What is the difference between these two part numbers?

A: The PCX1D680MCS1GS and PCX1D680MCL1GS are both Nichicon PCX series aluminum polymer capacitors with identical electrical and mechanical specifications. Differences are limited to internal manufacturing codes or packaging batch designations that do not affect functional performance or interchangeability.

Q: Can I use these capacitors in high-ripple-current applications?

A: Both parts support a ripple current of 1.45 A at 100 kHz with an ESR of 34 mOhm. Application suitability depends on your specific circuit's ripple current requirements and thermal management conditions.
