Substitute Part Grouping Explanation

Substitution eligibility for the LLS1C563MELC is determined by strict equivalence across the following critical parameters:

• Capacitance value: 56000 µF (exact match required)
• Voltage rating: 16 V (exact match required)
• Tolerance: ±20% (exact match required)
• Package configuration: Radial, Can - Snap-In (exact match required)
• Mounting type: Through Hole (exact match required)
• Lead spacing: 0.394" (10.00 mm) (exact match required)
• Case diameter: 1.378" (35.00 mm) (exact match required)
• Operating temperature range: -40°C to 85°C (exact match required)
• Lifetime rating: 3000 Hrs @ 85°C (exact match required)
• Compliance certifications: ROHS3 Compliant, REACH Unaffected (exact match required)

The SLPX563M016H4P3 manufactured by Cornell Dubilier Electronics (CDE) meets all substitution criteria and is classified as an equivalent part.

Parameter Comparison

Engineering Selection Recommendations

Both the LLS1C563MELC and SLPX563M016H4P3 are active production components with identical electrical ratings, mechanical dimensions, and compliance certifications. Selection between these parts may be based on:

• Inventory availability and lead time requirements
• ESR specifications: The SLPX563M016H4P3 provides specified ESR of 12 mOhm @ 120 Hz, whereas the LLS1C563MELC does not specify this parameter
• Ripple current performance: Both parts meet general-purpose application requirements with comparable ripple current ratings at 120 Hz
• Physical height tolerance: The SLPX563M016H4P3 has a maximum seated height of 1.772" (45.00 mm) compared to 1.850" (47.00 mm) for the LLS1C563MELC, which may be relevant for space-constrained applications

Both parts satisfy ROHS3 compliance and REACH regulatory requirements for equivalent substitution.

Frequently Asked Questions (FAQ)

Q: Can the SLPX563M016H4P3 be used as a direct replacement for the LLS1C563MELC?

A: Yes. Both parts share identical capacitance (56000 µF), voltage rating (16 V), tolerance (±20%), package configuration (Radial, Can - Snap-In), lead spacing (0.394" / 10.00 mm), case diameter (1.378" / 35.00 mm), lifetime rating (3000 Hrs @ 85°C), and operating temperature range (-40°C to 85°C). Both are ROHS3 compliant and REACH unaffected.

Q: Are there physical dimension differences between these parts?

A: The maximum seated height differs: LLS1C563MELC is 1.850" (47.00 mm) and SLPX563M016H4P3 is 1.772" (45.00 mm). This 2 mm difference may be relevant for applications with strict height constraints.

Q: What is the significance of the ESR specification on the SLPX563M016H4P3?

A: The SLPX563M016H4P3 specifies ESR of 12 mOhm @ 120 Hz. The LLS1C563MELC does not provide this specification. ESR affects ripple current handling and thermal performance; the specified value on the CDE part provides additional design certainty for applications sensitive to impedance characteristics.

Q: Are both parts suitable for the same applications?

A: Both parts are rated for general-purpose applications with identical electrical and thermal specifications. Application suitability depends on specific circuit requirements and physical space constraints.

Q: What compliance certifications apply to both parts?

A: Both the LLS1C563MELC and SLPX563M016H4P3 are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component procurement.
