SLP681M200C7P3 Equivalent & Substitute Parts

Part Overview

The SLP681M200C7P3 is a 680 µF, 200 V aluminum electrolytic capacitor in a radial, can snap-in package manufactured by Cornell Dubilier Electronics (CDE). This component is classified as obsolete, though 682 pieces remain in stock as new original inventory. The part operates across a temperature range of -25°C to 105°C with a rated lifetime of 3000 hours at 105°C and an equivalent series resistance (ESR) of 293 mOhm.

Due to the obsolete product status, identifying equivalent and substitute parts is necessary to ensure continued availability for maintenance, repair, and new design implementations. Substitute parts must maintain electrical compatibility while meeting the same or superior performance specifications.

Frequently Asked Questions (FAQ)

Q: Can SLP681M200C5P3 be used as a direct replacement for SLP681M200C7P3?

A: Yes. SLP681M200C5P3 is a direct electrical and mechanical substitute. Both parts share identical capacitance (680 µF), voltage rating (200 V), tolerance (±20%), ESR (293 mOhm), and lifetime specifications (3000 Hrs @ 105°C). Lead spacing (10.00 mm) and package type (radial snap-in) are identical. The primary difference is reduced height (35.00 mm versus 40.00 mm), which provides improved space efficiency without compromising performance.

Q: What is the difference between the CDE SLP series and the EPCOS B43508 series?

A: Both series meet the same electrical specifications (680 µF, 200 V, ±20% tolerance, 3000 Hrs @ 105°C). The primary difference is ESR performance: B43508B2687M000 specifies 170 mOhm @ 100Hz, while SLP parts specify 293 mOhm. The EPCOS part also extends the operating temperature range to -40°C ~ 105°C. Both are RoHS3 compliant and suitable for general-purpose applications. Selection depends on whether lower ESR performance is required for the specific application.

A: Yes, for applications where the circuit voltage does not exceed 200 V. The 220 V rated part provides additional voltage margin and is electrically compatible. Physical dimensions are identical (25.00 mm diameter, 40.00 mm height, 10.00 mm lead spacing). This substitution is suitable when higher voltage headroom is beneficial for circuit reliability.

Q: Are SLP681M200A9P3 and SLP681M200E3P3 suitable substitutes?

A: These parts are electrically equivalent but feature different physical dimensions. SLP681M200A9P3 has a smaller diameter (22.00 mm) with greater height (50.00 mm). SLP681M200E3P3 has a larger diameter (30.00 mm) with reduced height (30.00 mm). Substitution is possible only if the alternative form factor fits the PCB layout and mounting constraints. Lead spacing remains 10.00 mm on both parts.

Q: What compliance certifications apply to all substitute parts?

A: All substitute parts listed maintain RoHS3 compliance, REACH unaffected status, and Moisture Sensitivity Level 1 (unlimited). These certifications ensure compatibility with modern manufacturing and environmental standards.

Q: Which substitute part offers the best performance improvement?

A: B43508B2687M000 provides the lowest ESR (170 mOhm @ 100Hz) and extended temperature range (-40°C ~ 105°C). 381LX681M200J042 also extends the temperature range to -40°C ~ 105°C and includes specified ripple current ratings. Selection depends on whether lower ESR or extended temperature performance is required for the application.

Q: Is inventory availability a consideration for part selection?

A: Yes. SLP681M200C5P3 offers the highest inventory level (2664 pieces), ensuring long-term availability. 381LX681M200J042 (875 pieces), SLP681M220C7P3 (1048 pieces), and B43508B2687M000 (1384 pieces) also maintain substantial stock levels.
