Key Parameters

Substitute Part Grouping Explanation

Substitution for the LP272M025C1P3 is determined by maintaining identical capacitance (2700 µF) and compatible electrical and mechanical parameters. The following criteria establish valid substitute relationships:

Critical Parameters (Must Match):

• Capacitance: 2700 µF
• Tolerance: ±20%
• Lead Spacing: 0.394" (10.00 mm)
• Package / Case: Radial, Can - Snap-In
• Mounting Type: Through Hole
• Operating Temperature Range: -40°C ~ 105°C
• Polarization: Polar

Variable Parameters (May Differ):

• Voltage Rating: May be equal or higher
• ESR: May be lower (improved performance)
• Lifetime @ Temperature: May be extended
• Ripple Current Ratings: Scale with voltage capability

Two substitute models are identified: LP272M035C1P3 (equivalent with intermediate voltage rating) and SLP272M050C1P3 (upgrade with higher voltage rating and extended operational lifetime).

Engineering Selection Recommendations

LP272M025C1P3 (Original Specification) Selection is appropriate for circuits with 25 V supply voltage requirements where board space and cost are primary constraints. All three models maintain Active product status and ROHS3 compliance, ensuring regulatory alignment and long-term availability.

LP272M035C1P3 (Intermediate Voltage Equivalent) This model is functionally equivalent with a 35 V voltage rating and lower ESR (155 mOhm versus 180 mOhm). Selection applies to designs operating at voltage levels exceeding 25 V but not exceeding 35 V, or where improved ESR performance benefits signal integrity. Identical board footprint and mounting configuration enable direct substitution with no layout modifications required.

SLP272M050C1P3 (Upgraded Performance) This model provides the highest voltage rating (50 V) with extended operational lifetime (3000 Hrs at 105°C versus 1000 Hrs). Selection applies to applications requiring enhanced voltage margin, increased ripple current capacity, or extended service intervals. Higher voltage rating provides design margin for voltage transient protection. Identical mechanical dimensions ensure pin-compatible replacement.

All three models share identical mechanical specifications, lead spacing, and mounting type, enabling direct board-level interchange without PCB redesign.

Frequently Asked Questions (FAQ)

Q: Can LP272M035C1P3 or SLP272M050C1P3 be used as direct replacements for LP272M025C1P3? A: Direct electrical and mechanical substitution is valid. Both substitute models maintain identical capacitance (2700 µF), tolerance (±20%), lead spacing (10.00 mm), package style (Radial Can - Snap-In), and operating temperature range (-40°C to 105°C). No PCB modification is required.

Q: What is the advantage of the SLP272M050C1P3 over the LP272M025C1P3? A: The SLP272M050C1P3 provides three key advantages: higher voltage rating (50 V versus 25 V) for increased voltage margin, extended operational lifetime (3000 Hrs at 105°C versus 1000 Hrs), and higher ripple current capacity (1.8 A at 120 Hz versus 1 A). The ESR is slightly lower (172 mOhm), benefiting applications sensitive to impedance.

Q: Is the LP272M035C1P3 equivalent to the LP272M025C1P3? A: Yes. The LP272M035C1P3 is equivalent with the primary difference being voltage rating (35 V versus 25 V) and improved ESR (155 mOhm versus 180 mOhm). Capacitance, tolerance, mechanical dimensions, and mounting configuration are identical. Board-level substitution requires no design changes.

Q: What does the voltage rating difference mean for circuit design? A: Voltage rating indicates the maximum DC voltage the capacitor tolerates without risk of permanent damage or failure. A 35 V or 50 V capacitor can be used in 25 V circuits with voltage margin. However, circuits operating above 25 V require a capacitor rated at or above the operating voltage.

Q: Why does SLP272M050C1P3 have longer lifetime (3000 Hrs) compared to 1000 Hrs? A: Lifetime rating reflects accelerated aging at 105°C (the maximum rated temperature). Higher voltage-rated capacitors in this series typically incorporate improved dielectric and electrode materials, extending operational life under thermal stress. The 3000 Hrs rating indicates superior long-term reliability in high-temperature applications.

Q: Are all three models RoHS compliant? A: All three models are ROHS3 Compliant, meeting regulatory requirements for lead-free and restricted substance elimination in electronic components.
