Engineering Selection Recommendations

All three parts—PLF1C101MDL4, RNE1C101MDS1PX, and RR71C101MDN1—are electrically and functionally equivalent for general-purpose 100 µF, 16 V aluminum polymer capacitor applications. Each part maintains ROHS3 compliance, active production status, and identical electrical specifications for capacitance, voltage rating, tolerance, and operating temperature range.

Selection between these parts should be based on:

Packaging availability: PLF1C101MDL4 and RR71C101MDN1 are supplied in Bulk packaging; RNE1C101MDS1PX is supplied in Cut Tape (CT) packaging.
Physical dimensions and lead spacing: Verify that the selected part's footprint and lead spacing are compatible with the printed circuit board layout. The three parts differ in diameter, height, and lead spacing.
ESR and ripple current performance: RR71C101MDN1 offers the lowest ESR (7 mOhm) and highest ripple current capability (5.6 A @ 100 kHz), suitable for high-frequency switching applications. PLF1C101MDL4 provides mid-range performance (24 mOhm, 2.9 A @ 100 kHz). RNE1C101MDS1PX has the highest ESR (35 mOhm) and lowest ripple current (2.3 A @ 100 kHz).
Inventory and supply chain: All three parts are in active stock with Nichicon.

Frequently Asked Questions (FAQ)

Q: Can RNE1C101MDS1PX be used as a direct replacement for PLF1C101MDL4?

A: Yes. Both parts are electrically equivalent with identical capacitance (100 µF), voltage rating (16 V), tolerance (±20%), operating temperature range (-55°C ~ 105°C), and lifetime rating (2000 Hrs @ 105°C). However, RNE1C101MDS1PX has different physical dimensions and lead spacing, so PCB layout compatibility must be confirmed before substitution.

Q: Can RR71C101MDN1 be used as a direct replacement for PLF1C101MDL4?

A: Yes. Both parts are electrically equivalent with identical capacitance, voltage rating, tolerance, operating temperature range, and lifetime rating. RR71C101MDN1 offers superior ESR performance (7 mOhm versus 24 mOhm) and higher ripple current capability (5.6 A @ 100 kHz versus 2.9 A @ 100 kHz). Physical dimensions and lead spacing differ, requiring PCB layout verification.

Q: What is the difference in ESR between these parts?

A: PLF1C101MDL4 has 24 mOhm ESR, RNE1C101MDS1PX has 35 mOhm ESR, and RR71C101MDN1 has 7 mOhm ESR. Lower ESR reduces heat generation and improves performance in high-frequency ripple current applications. Selection depends on the specific thermal and ripple current requirements of the application.

Q: Are all three parts RoHS compliant?

A: Yes. All three parts—PLF1C101MDL4, RNE1C101MDS1PX, and RR71C101MDN1—are ROHS3 compliant and REACH unaffected.

Q: What packaging formats are available?

A: PLF1C101MDL4 and RR71C101MDN1 are supplied in Bulk packaging. RNE1C101MDS1PX is supplied in Cut Tape (CT) packaging. Packaging selection affects handling, storage, and automated assembly compatibility.

Q: Do these parts have different physical footprints?

A: Yes. The three parts have different diameters, heights, and lead spacing. PLF1C101MDL4 has a 6.30 mm diameter with 2.50 mm lead spacing. RNE1C101MDS1PX has a 5.00 mm diameter with 5.00 mm lead spacing. RR71C101MDN1 has an 8.00 mm diameter with 4.60 mm lead spacing. PCB layout must accommodate the selected part's physical dimensions.
