LLK1C103MHSA Equivalent & Substitute Parts

Part Overview

The LLK1C103MHSA is a 10000 µF, 16 V aluminum electrolytic capacitor manufactured by Nichicon in a radial, can snap-in package. This component is classified as obsolete, making equivalent substitutes necessary for new designs and ongoing production support. The part serves general-purpose applications requiring high capacitance energy storage in through-hole configurations with standard 10 mm lead spacing.

Key Parameters

Voltage Rating	16 V
Tolerance	±20%
Package Type	Radial, Can - Snap-In
Mounting Type	Through Hole
Lead Spacing	0.394" (10.00 mm)
Operating Temperature Range	-40°C ~ 85°C
Polarization	Polar

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence in the following parameters:

Capacitance: 10000 µF (exact match required)
Voltage Rating: 16 V (exact match required)
Tolerance: ±20% (exact match required)
Package Type: Radial, Can - Snap-In (exact match required)
Lead Spacing: 0.394" (10.00 mm) (exact match required)
Mounting Type: Through Hole (exact match required)
Polarization: Polar (exact match required)

All four substitute parts meet these core electrical and mechanical criteria. Variations in lifetime rating, ESR, ripple current capacity, physical dimensions (diameter and height), operating temperature range, and product status are secondary considerations that do not disqualify substitution but may affect application suitability.

Engineering Selection Recommendations

All four substitute parts are electrically and mechanically compatible with the LLK1C103MHSA based on core parameters. Selection should prioritize active product status and compliance certifications:

LLS1C103MELZ (Nichicon) maintains manufacturer continuity within the Nichicon product line and offers improved lifetime (3000 Hrs @ 85°C versus 2000 Hrs). This part is active and suitable for direct replacement in applications where Nichicon sourcing is preferred.

SLP103M016C1P3 (Cornell Dubilier Electronics) provides the highest operating temperature range (-40°C ~ 105°C) and specified ESR (66 mOhm @ 120 Hz). ROHS3 compliance and active status support long-term availability. This part is suitable for applications requiring extended temperature performance.

380LX103M016J012 (Cornell Dubilier Electronics) offers the highest ripple current capacity (3.8 A @ 120 Hz) and is ROHS3 compliant. This part is appropriate for applications with elevated ripple current demands.

SLPX103M016A3P3 (Cornell Dubilier Electronics) provides balanced performance with 3000 Hrs lifetime @ 85°C, specified ESR (66 mOhm @ 120 Hz), and ROHS3 compliance. This part is suitable for general-purpose replacement applications.

Frequently Asked Questions (FAQ)

Q: Can I use any of these substitute parts as a direct replacement for the LLK1C103MHSA?

A: Yes. All four substitute parts meet the core electrical and mechanical requirements: 10000 µF capacitance, 16 V voltage rating, ±20% tolerance, radial snap-in package, 10 mm lead spacing, and through-hole mounting. Physical board layout compatibility depends on verifying the specific diameter and height dimensions of the selected substitute against available PCB space.

Q: What are the physical dimension differences between substitute parts?

A: The LLK1C103MHSA has a 0.984" diameter and 0.984" height. LLS1C103MELZ measures 0.866" diameter and 1.181" height. SLP103M016C1P3 matches the original at 0.984" diameter and 0.984" height. 380LX103M016J012 measures 0.984" diameter and 1.063" height. SLPX103M016A3P3 measures 0.866" diameter and 1.181" height. Verify available PCB space before selection.

Q: Which substitute offers the longest operational lifetime?

A: All substitute parts except LLS1C103MELZ offer 3000 Hrs @ 85°C lifetime, compared to the original 2000 Hrs @ 85°C. SLP103M016C1P3 additionally supports 3000 Hrs @ 105°C, providing extended performance at elevated temperatures.

Q: Are all substitute parts RoHS compliant?

A: The three Cornell Dubilier Electronics parts (SLP103M016C1P3, 380LX103M016J012, and SLPX103M016A3P3) are ROHS3 compliant. RoHS status for LLS1C103MELZ is not specified in the provided data.

Q: What is the difference in ripple current capacity?

A: Ripple current @ 120 Hz varies: LLK1C103MHSA (2.85 A), LLS1C103MELZ (2.89 A), SLP103M016C1P3 (2.6 A), 380LX103M016J012 (3.8 A), and SLPX103M016A3P3 (2.89 A). Applications with high ripple current demands should prioritize 380LX103M016J012.

Q: Can I use SLP103M016C1P3 in applications requiring operation above 85°C?

A: Yes. SLP103M016C1P3 supports operation up to 105°C, with a rated lifetime of 3000 Hrs @ 105°C. Other substitutes are rated to 85°C maximum.
