LP272M035C1P3 Equivalent & Substitute Parts

Part Overview

The LP272M035C1P3 is a 2700 µF, 35 V aluminum electrolytic capacitor manufactured by Cornell Dubilier Electronics (CDE) in a radial, can snap-in package. This component is classified as Active product status and is designed for general-purpose applications requiring stable capacitance and low equivalent series resistance in through-hole mounting configurations.

Substitute parts are identified when design requirements permit operation at higher voltage ratings or when extended operational lifetime specifications are required, while maintaining identical capacitance values, physical dimensions, and mounting compatibility.

Substitute Part Grouping Explanation

Substitution of the LP272M035C1P3 is permitted with the SLP272M050C1P3 based on the following engineering criteria:

Identical Parameters:

• Capacitance: 2700 µF (both parts)
• Tolerance: ±20% (both parts)
• Physical dimensions: 0.984" diameter, 0.984" height (both parts)
• Lead spacing: 10.00 mm (both parts)
• Package type: Radial, Can - Snap-In (both parts)
• Mounting type: Through Hole (both parts)
• Operating temperature range: -40°C to 105°C (both parts)
• Polarization: Polar (both parts)
• RoHS3 Compliance: Yes (both parts)
• MSL Rating: 1 - Unlimited (both parts)

Differing Parameters Permitting Substitution:

• Voltage rating: 35 V (LP272M035C1P3) vs. 50 V (SLP272M050C1P3) — higher voltage rating in substitute allows operation in circuits designed for 35 V
• ESR @ 120Hz: 155 mOhm (LP272M035C1P3) vs. 172 mOhm (SLP272M050C1P3) — acceptable variance within general-purpose application tolerance
• Lifetime @ 105°C: 1000 Hrs (LP272M035C1P3) vs. 3000 Hrs (SLP272M050C1P3) — extended lifetime in substitute provides improved reliability margin

Parameter Comparison

Engineering Selection Recommendations

LP272M035C1P3 Selection Criteria:

• Use when circuit design specifies 35 V maximum operating voltage
• Applications with space constraints where 1000-hour lifetime at 105°C meets reliability requirements
• Cost-sensitive designs where lower voltage rating is sufficient

SLP272M050C1P3 Selection Criteria:

• Use when circuit design permits 50 V operation or when 35 V is the nominal specification with margin requirements
• Applications requiring extended operational lifetime (3000 hours at 105°C vs. 1000 hours)
• Designs where higher voltage headroom improves system reliability
• Both parts maintain Active product status and full RoHS3 compliance, ensuring continued availability and regulatory conformance

The substitute part SLP272M050C1P3 is electrically and mechanically compatible with LP272M035C1P3 in all through-hole mounting applications where the higher voltage rating does not conflict with circuit design specifications.

Frequently Asked Questions (FAQ)

Q: Can SLP272M050C1P3 directly replace LP272M035C1P3 in my circuit?

A: Yes, provided your circuit design operates at or below 35 V. The substitute part is rated for 50 V, making it suitable for 35 V applications. Physical dimensions, lead spacing, and mounting type are identical, ensuring direct PCB compatibility.

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

A: LP272M035C1P3 has 155 mOhm ESR at 120 Hz, while SLP272M050C1P3 has 172 mOhm ESR at 120 Hz. This 17 mOhm difference is within acceptable variance for general-purpose aluminum electrolytic capacitors and does not affect functional compatibility in standard applications.

Q: Why does the substitute part have a longer lifetime specification?

A: SLP272M050C1P3 is rated for 3000 hours at 105°C compared to 1000 hours for LP272M035C1P3. This extended lifetime reflects the design characteristics of the higher voltage-rated component and provides improved reliability margin in thermal stress conditions.

Q: Are both parts RoHS3 compliant?

A: Yes, both LP272M035C1P3 and SLP272M050C1P3 are ROHS3 compliant with MSL Rating 1 (Unlimited), ensuring regulatory conformance and suitability for current manufacturing standards.

Q: What is the lead spacing for these capacitors?

A: Both parts have identical lead spacing of 10.00 mm (0.394"), ensuring direct compatibility with existing PCB layouts designed for either component.

Q: Can I use LP272M035C1P3 in a circuit designed for SLP272M050C1P3?

A: No. The LP272M035C1P3 is rated for 35 V maximum, while SLP272M050C1P3 is rated for 50 V. Using the lower-rated part in a 50 V circuit exceeds its voltage specification and creates reliability risk.
