PCF0G681MCL1GS Equivalent & Substitute Parts

Part Overview

The PCF0G681MCL1GS is a 680 µF, 4 V aluminum polymer capacitor manufactured by Nichicon in the PCF series. This surface mount component is designed for general purpose applications requiring stable capacitance and low equivalent series resistance. The part is currently active in production with ROHS3 compliance and REACH affected status. Substitute parts are identified when equivalent electrical specifications, mechanical compatibility, and packaging standards align with the original component's functional requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict adherence to the following parameters:

• Capacitance value: 680 µF (exact match required)
• Voltage rating: 4 V (exact match required)
• Tolerance: ±20% (exact match required)
• Type: Aluminum Polymer (exact match required)
• Mounting: Surface Mount (exact match required)
• Package: Radial, Can - SMD (exact match required)
• Operating temperature range: -55°C to 105°C (exact match required)

All identified substitute parts meet these core electrical and mechanical criteria. Variations in ESR, ripple current capacity, physical dimensions, and lifetime ratings are secondary parameters that may influence selection based on specific application requirements but do not disqualify substitution eligibility.

Parameter Comparison

Engineering Selection Recommendations

All four parts meet the core substitution criteria for 680 µF, 4 V aluminum polymer capacitors in surface mount radial can packages. Selection among these alternatives depends on application-specific constraints:

PCJ0G681MCL1GS offers reduced ESR at 13 mOhm compared to the original PCF0G681MCL1GS at 17 mOhm, with equivalent 2000 hour lifetime rating. This part features a smaller physical footprint (8.00 mm diameter versus 10.00 mm), which may require PCB layout verification for land pattern compatibility.

RHA0G681MCN1GS provides the lowest ESR at 8 mOhm with the same 2000 hour lifetime, also in the smaller 8.00 mm package. REACH unaffected status may be advantageous for certain supply chain requirements.

APXA4R0ARA681MJ80G from Chemi-Con maintains the original 10.00 mm package footprint and offers extended lifetime of 15000 hours at 105°C. ESR is 20 mOhm, slightly higher than the original. REACH unaffected status is provided.

All parts maintain ROHS3 compliance and identical electrical specifications for capacitance, voltage, and tolerance.

Frequently Asked Questions (FAQ)

Q: Can PCJ0G681MCL1GS be used as a direct replacement for PCF0G681MCL1GS?

A: PCJ0G681MCL1GS meets all core electrical specifications (680 µF, 4 V, ±20%, polymer type, surface mount). However, the physical package differs: PCJ is 8.00 mm diameter while PCF is 10.00 mm diameter. PCB land pattern compatibility must be verified before substitution.

Q: What is the significance of ESR differences among these parts?

A: ESR values range from 8 mOhm (RHA0G681MCN1GS) to 20 mOhm (APXA4R0ARA681MJ80G). Lower ESR reduces heat generation and improves ripple current handling. Selection depends on application ripple current requirements and thermal constraints.

Q: Does lifetime rating affect substitution eligibility?

A: Lifetime rating is a secondary parameter. All parts meet the minimum 2000 hour requirement at 105°C. APXA4R0ARA681MJ80G offers 15000 hours, providing extended operational life for applications requiring higher reliability margins.

Q: Are there PCB layout considerations for smaller package alternatives?

A: Yes. PCJ0G681MCL1GS and RHA0G681MCN1GS use 8.30 mm x 8.30 mm land patterns, while PCF0G681MCL1GS and APXA4R0ARA681MJ80G use 10.30 mm x 10.30 mm patterns. Verify PCB footprint compatibility before design implementation.

Q: What is the difference between REACH Affected and REACH Unaffected status?

A: REACH Affected indicates the part contains substances of concern requiring compliance documentation. REACH Unaffected parts do not contain these substances. Selection depends on supply chain and regulatory requirements for the end application.

Q: Can these parts be used interchangeably in high ripple current applications?

A: Ripple current capacity varies: RHA0G681MCN1GS supports 5 A at 100 kHz, while PCJ0G681MCL1GS supports 3.95 A. Application ripple current specifications must be matched to the selected part's rated capacity.
