Parameter Comparison

Engineering Selection Recommendations

SLP682M025C1P3 Selection Criteria: This part is the primary direct equivalent to SLP682M025A3P3. Both components share identical electrical specifications, including 6800 µF capacitance, 25 V voltage rating, ±20% tolerance, 88 mOhm ESR @ 120Hz, and 3000 hour lifetime at 105°C. Both are members of the SLP0712TE series and maintain ROHS3 compliance. Physical dimensions differ slightly (0.984" diameter and 0.984" height versus 0.866" diameter and 1.181" height), but lead spacing remains constant at 0.394" (10.00mm), ensuring PCB footprint compatibility. This substitute is suitable for direct replacement in applications where the slightly larger can diameter and reduced height do not present mechanical constraints.

381LX682M025J012 Selection Criteria: This part provides functional equivalence with matching 6800 µF capacitance, 25 V voltage rating, and 3000 hour lifetime at 105°C. The 381LX series designation indicates a different manufacturer series. Physical dimensions are larger (0.984" diameter, 1.063" height), and ripple current at 20 kHz is specified at 2.8 A versus 3 A for the primary part. ESR is not specified for this part. Lead spacing remains 0.394" (10.00mm). This substitute is applicable when the larger physical envelope is accommodated by the design and when the slightly reduced high-frequency ripple current rating is acceptable for the application.

SLP682M035A7P3 Selection Criteria: This part is a higher voltage variant rated at 35 V versus 25 V, maintaining the same 6800 µF capacitance and 3000 hour lifetime at 105°C. The 35 V rating provides voltage derating margin for applications operating below 25 V nominal. ESR is specified at 78 mOhm, which is lower than the primary part's 88 mOhm, indicating improved high-frequency performance. Physical dimensions differ significantly (0.866" diameter, 1.575" height), requiring verification of mechanical clearance. This substitute is selected when applications require voltage margin or when the improved ESR characteristic is beneficial. Lead spacing remains 0.394" (10.00mm).

Compliance and Certification: All substitute parts maintain ROHS3 compliance, MSL rating of 1 (Unlimited), REACH Unaffected status, and EAR99 ECCN classification, ensuring regulatory and supply chain compatibility with the primary part.

Frequently Asked Questions (FAQ)

Q1: Can SLP682M025C1P3 be used as a direct drop-in replacement for SLP682M025A3P3?

A: SLP682M025C1P3 is electrically and functionally equivalent to SLP682M025A3P3. Both parts share identical capacitance (6800 µF), voltage rating (25 V), tolerance (±20%), ESR (88 mOhm @ 120Hz), and lifetime (3000 Hrs @ 105°C). Lead spacing is identical at 0.394" (10.00mm), ensuring PCB footprint compatibility. Physical dimensions differ slightly: SLP682M025C1P3 has a diameter of 0.984" and height of 0.984", while SLP682M025A3P3 has a diameter of 0.866" and height of 1.181". Verify that the larger diameter and reduced height of SLP682M025C1P3 do not conflict with mechanical constraints in your assembly.

Q2: What are the key differences between 381LX682M025J012 and SLP682M025A3P3?

A: Both parts maintain 6800 µF capacitance, 25 V voltage rating, ±20% tolerance, and 3000 hour lifetime at 105°C. The primary differences are: (1) Series designation: 381LX versus SLP0712TE; (2) Physical dimensions: 381LX682M025J012 is larger (0.984" diameter, 1.063" height) compared to SLP682M025A3P3 (0.866" diameter, 1.181" height); (3) High-frequency ripple current: 381LX682M025J012 is rated at 2.8 A @ 20 kHz versus 3 A @ 20 kHz for SLP682M025A3P3; (4) ESR specification: ESR is not provided for 381LX682M025J012. Lead spacing remains constant at 0.394" (10.00mm). This substitute is suitable when the larger physical envelope is acceptable and the slightly reduced high-frequency ripple current rating meets application requirements.

Q3: When should SLP682M035A7P3 be selected over SLP682M025A3P3?

A: SLP682M035A7P3 is selected when applications require voltage derating margin or when improved ESR performance is beneficial. This part maintains the same 6800 µF capacitance and 3000 hour lifetime at 105°C but is rated at 35 V instead of 25 V, providing additional voltage safety margin for circuits operating below 25 V nominal. The ESR is specified at 78 mOhm, which is lower than SLP682M025A3P3's 88 mOhm, resulting in improved high-frequency performance and reduced heat generation. Physical dimensions are different (0.866" diameter, 1.575" height), requiring verification of mechanical clearance in the assembly. Lead spacing remains 0.394" (10.00mm).

Q4: Are all substitute parts ROHS3 compliant?

A: Yes. SLP682M025C1P3, 381LX682M025J012, and SLP682M035A7P3 are all ROHS3 compliant, matching the compliance status of SLP682M025A3P3. All parts maintain MSL rating of 1 (Unlimited), REACH Unaffected status, and EAR99 ECCN classification.

Q5: What is the significance of lead spacing in substitution?

A: Lead spacing of 0.394" (10.00mm) is critical for PCB footprint compatibility. All substitute parts maintain this identical lead spacing, ensuring that the through-hole mounting holes on the printed circuit board remain aligned with the component leads. While physical diameter and height may vary between parts, the constant lead spacing guarantees mechanical compatibility with existing PCB designs without requiring layout modifications.

Q6: How do ripple current ratings affect part selection?

A: Ripple current ratings specify the maximum AC current the capacitor can safely handle at specified frequencies without exceeding temperature limits. SLP682M025A3P3 is rated at 2.4 A @ 120 Hz and 3 A @ 20 kHz. SLP682M025C1P3 matches these ratings exactly. 381LX682M025J012 is rated at 2.4 A @ 120 Hz but only 2.8 A @ 20 kHz, which is slightly lower. If your application requires the full 3 A @ 20 kHz ripple current, 381LX682M025J012 may not be suitable. Verify that the substitute part's ripple current rating meets or exceeds your circuit's requirements at the operating frequency.

Q7: Can physical dimension differences affect circuit performance?

A: Physical dimension differences do not directly affect electrical performance, as capacitance, voltage rating, ESR, and ripple current are independent of can size. However, larger physical dimensions may present mechanical constraints in compact assemblies. SLP682M025C1P3 has a larger diameter (0.984" versus 0.866") but reduced height (0.984" versus 1.181"). SLP682M035A7P3 has the same diameter as the primary part but significantly greater height (1.575" versus 1.181"). Verify that the substitute part's dimensions fit within the available space on your PCB and within the enclosure.

Q8: What does ESR (Equivalent Series Resistance) indicate?

A: ESR represents the internal resistance of the capacitor at a specified frequency, typically 120 Hz. Lower ESR values indicate better high-frequency performance and reduced heat generation during ripple current operation. SLP682M025A3P3 and SLP682M025C1P3 both specify 88 mOhm @ 120Hz. SLP682M035A7P3 specifies 78 mOhm, which is lower and indicates superior performance. 381LX682M025J012 does not provide ESR specification. If ESR is critical to your application, verify that the substitute part's ESR meets your requirements.

Q9: Are there any temperature-related considerations for substitution?

A: All substitute parts maintain the same operating temperature range of -40°C to 105°C and the same lifetime specification of 3000 hours at 105°C as SLP682M025A3P3. Temperature performance is therefore equivalent across all parts. No additional thermal analysis is required for substitution based on temperature specifications alone.

Q10: What inventory considerations apply to these substitute parts?

A: Current inventory levels are: SLP682M025A3P3 (991 Pcs), SLP682M025C1P3 (5333 Pcs), 381LX682M025J012 (3457 Pcs), and SLP682M035A7P3 (2934 Pcs). All parts are classified as Active product status with new original stock available. Inventory availability should be considered in procurement planning, particularly if long-term supply continuity is required.
