Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SLP151M350C3P3 must maintain compatibility across the following critical parameters:

Mandatory Equivalence Criteria:

• Capacitance: 150 µF (identical)
• Tolerance: ±20% (identical)
• Package / Case: Radial, Can - Snap-In (identical)
• Lead Spacing: 0.394" (10.00 mm) (identical)
• Size / Dimension: 0.984" Dia (25.00 mm) (identical)
• Height - Seated (Max): 1.260" (32.00 mm) (identical)
• Mounting Type: Through Hole (identical)
• Polarization: Polar (identical)
• Applications: General Purpose (identical)

Permissible Upgrade Parameters:

• Voltage - Rated: Substitutes rated at 450 V exceed the 350 V original requirement, providing higher voltage headroom
• Lifetime @ 105°C: Substitutes rated at 5000 Hrs exceed the 3000 Hrs original specification
• ESR: Lower ESR values in substitutes improve thermal performance and ripple current handling
• Ripple Current: Higher ratings at specified frequencies indicate improved performance margins

All four substitute parts meet these criteria through voltage upgrade (350 V to 450 V) while maintaining identical mechanical and electrical core specifications. Substitutes are sourced from manufacturers including Rubycon, EPCOS - TDK Electronics, and Nichicon, all with active product status and ROHS3 compliance.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts are active products with ROHS3 compliance and REACH Unaffected status, meeting current environmental and regulatory requirements.

Voltage Upgrade Performance: All four substitutes are rated at 450 V, providing 100 V additional voltage margin over the original 350 V specification. This upgrade does not affect form factor or mounting compatibility.

Lifetime Selection:

• Parts with 5000 Hrs @ 105°C (450VXG150MEFCSN25X30, 450VXH150MEFCSN25X30, LGX2W151MELA30) provide extended operational life versus the original 3000 Hrs specification.
• Parts with 3000 Hrs @ 105°C (B43508B5157M000) match the original lifetime rating.

Temperature Range Consideration: The EPCOS - TDK part (B43508B5157M000) extends the lower operating temperature to -40°C, compared to -25°C for all other options, providing wider temperature envelope coverage.

Inventory Availability: The 450VXH150MEFCSN25X30 from Rubycon offers the highest inventory level at 274,082 units, followed by 450VXG150MEFCSN25X30 at 3,200 units, LGX2W151MELA30 at 3,348 units, and B43508B5157M000 at 1,064 units.

Frequently Asked Questions (FAQ)

Q: Can the SLP151M350C3P3 be directly replaced with a 450 V rated substitute? A: Yes. All substitutes maintain identical capacitance (150 µF), tolerance (±20%), physical dimensions, lead spacing, and mounting configuration. The higher voltage rating (450 V vs. 350 V) provides additional design margin without affecting circuit board layout or mechanical fit.

Q: What determines if a part qualifies as an equivalent substitute? A: Equivalent substitutes must match capacitance value, tolerance, package type (Radial, Can - Snap-In), lead spacing (0.394"), physical dimensions (0.984" diameter, 1.260" maximum height), mounting type (Through Hole), and polarization (Polar). Voltage rating and lifetime are permitted to upgrade while maintaining full compatibility.

Q: Are there differences in ripple current handling between the original and substitute parts? A: Yes. Ripple current specifications vary by frequency and manufacturer. The original SLP151M350C3P3 is rated at 830 mA @ 120 Hz and 1.22 A @ 20 kHz. Substitutes show varying performance at different frequencies. Selection should consider specific application frequency requirements.

Q: Do substitute parts require circuit board layout modifications? A: No. All substitutes share identical lead spacing (0.394"), case diameter (0.984"), and maximum seated height (1.260"), ensuring direct mechanical compatibility with existing PCB designs without alteration.

Q: Which substitute offers the longest operational lifetime? A: Three substitutes (450VXG150MEFCSN25X30, 450VXH150MEFCSN25X30, and LGX2W151MELA30) are rated at 5000 Hrs @ 105°C, compared to 3000 Hrs for both the original part and the B43508B5157M000.

Q: Are all substitutes compliant with current environmental regulations? A: Yes. All substitute parts are ROHS3 Compliant and REACH Unaffected, meeting current environmental and chemical substance restrictions.
