Substitute Part Grouping Explanation

Substitution eligibility for aluminum polymer capacitors is determined by strict equivalence across the following parameters:

Primary Equivalence Criteria:

Capacitance value: 330 µF (exact match required)
Voltage rating: 16 V (exact match required)
Tolerance: ±20% (exact match required)
Type: Aluminum Polymer (exact match required)
Mounting type: Through Hole (exact match required)
Package style: Radial, Can (exact match required)
Operating temperature range: -55°C to 105°C (exact match required)
Lifetime specification: 2000 Hrs @ 105°C (exact match required)

Secondary Performance Parameters:

ESR (Equivalent Series Resistance): Lower values indicate improved performance but do not prevent substitution
Ripple current capability: Higher values indicate improved performance but do not prevent substitution
Physical dimensions: Variations in height and diameter are acceptable provided the component fits within the available board space and lead spacing remains compatible

All substitute parts listed meet the primary equivalence criteria. Variations in ESR, ripple current, and physical dimensions represent performance differences that may be advantageous depending on circuit requirements.

Engineering Selection Recommendations

All substitute parts listed are active products with current manufacturing status and full regulatory compliance. Selection among equivalent parts is based on the following engineering considerations:

PLF1C331MDO1 (Nichicon PLF Series): This substitute offers improved ESR performance at 9 mOhm compared to the original 14 mOhm specification, with increased ripple current capability of 6.1 A at 100 kHz. Physical dimensions are nearly identical to the main part, with lead spacing and diameter matching exactly. Height increases by 0.020" (0.50 mm). ROHS3 compliance provides enhanced regulatory alignment.

PLG1C331MCO1 (Nichicon PLG Series): This substitute features a more compact form factor with reduced diameter (0.315" vs. 0.394") and height (0.354" vs. 0.492"). Lead spacing is reduced to 0.138" (3.50 mm). ESR performance is 13 mOhm with ripple current of 4.7 A at 100 kHz. This option is suitable for space-constrained applications where the smaller footprint is advantageous and lead spacing compatibility exists.

RR71C331MDN1 (Nichicon FPCAP/RR7 Series): This substitute provides the lowest ESR specification at 7 mOhm with the highest ripple current capability at 6.1 A at 100 kHz. Physical dimensions match the main part in lead spacing and diameter, with maximum height of 0.551" (14.00 mm), representing a 0.059" (1.50 mm) increase. This option delivers superior performance characteristics for applications requiring minimal impedance and high ripple current handling.

All substitute parts maintain identical electrical specifications for capacitance, voltage rating, tolerance, operating temperature range, and lifetime rating. Selection should be based on available board space, lead spacing requirements, and performance optimization needs.

Frequently Asked Questions (FAQ)

Q: Can PLG1C331MCO1 be used as a direct replacement for APS-160ELL331MJC5S?

A: PLG1C331MCO1 meets all primary electrical equivalence criteria but features different physical dimensions and lead spacing. The reduced lead spacing of 0.138" (3.50 mm) versus 0.197" (5.00 mm) requires verification of PCB hole pattern compatibility. The smaller form factor (0.315" diameter, 0.354" height) fits within the space envelope of the original part but may not align with existing through-hole positions. Physical compatibility must be confirmed before substitution.

Q: What is the difference between ESR values across the substitute parts?

A: ESR (Equivalent Series Resistance) values range from 7 mOhm (RR71C331MDN1) to 14 mOhm (APS-160ELL331MJC5S). Lower ESR values reduce impedance and heat generation in high-frequency applications. RR71C331MDN1 and PLF1C331MDO1 offer improved ESR performance. PLG1C331MCO1 provides ESR of 13 mOhm, closely matching the original specification. ESR differences do not affect substitution eligibility but influence performance in ripple-current-sensitive circuits.

Q: Are all substitute parts RoHS compliant?

A: Yes. The original APS-160ELL331MJC5S is RoHS Compliant. All three substitute parts (PLF1C331MDO1, PLG1C331MCO1, and RR71C331MDN1) are ROHS3 Compliant, which represents an enhanced compliance standard. All parts are REACH Unaffected, confirming regulatory alignment for both original and substitute selections.

Q: What is the maximum height difference among these parts?

A: The original APS-160ELL331MJC5S has a maximum seated height of 0.492" (12.50 mm). PLF1C331MDO1 reaches 0.512" (13.00 mm), a difference of 0.020" (0.50 mm). RR71C331MDN1 reaches 0.551" (14.00 mm), a difference of 0.059" (1.50 mm). PLG1C331MCO1 is the most compact at 0.354" (9.00 mm). Height variations must be evaluated against available clearance in the target application.

Q: Do all parts share the same lead spacing?

A: No. APS-160ELL331MJC5S, PLF1C331MDO1, and RR71C331MDN1 all feature 0.197" (5.00 mm) lead spacing. PLG1C331MCO1 uses 0.138" (3.50 mm) lead spacing. Lead spacing compatibility with existing PCB hole patterns is critical for through-hole substitution. Verify hole spacing before selecting PLG1C331MCO1.

Q: Which substitute offers the best ripple current performance?

A: Both PLF1C331MDO1 and RR71C331MDN1 provide 6.1 A ripple current at 100 kHz, compared to 5.05 A for the original part. PLG1C331MCO1 provides 4.7 A at 100 kHz. RR71C331MDN1 additionally specifies ripple current at low frequency (610 mA @ 120 Hz). Selection depends on the frequency characteristics of the target application.

Q: Are all parts available in equivalent quantities?

A: Inventory levels vary. APS-160ELL331MJC5S has 935 units in stock. PLF1C331MDO1 has 1,541 units. PLG1C331MCO1 has 1,244 units. RR71C331MDN1 has 3,441 units. Availability should be confirmed for production requirements.
