CL10C181JB8NNWC Equivalent & Substitute Parts

Part Overview

The CL10C181JB8NNWC is a 180 pF ±5% 50V ceramic capacitor manufactured by Samsung Electro-Mechanics in the 0603 (1608 Metric) package with C0G/NP0 temperature coefficient. This multilayer ceramic capacitor (MLCC) is classified as Active product status with 814 pieces currently in stock. The component operates across -55°C to 125°C and is ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Substitute parts become necessary when addressing supply chain constraints, packaging format requirements (tape & reel versus bulk), automotive-grade certifications (AEC-Q200), enhanced tolerance specifications (±1% versus ±5%), or higher voltage ratings while maintaining identical capacitance and footprint compatibility.

Substitute Part Grouping Explanation

Substitution logic for the CL10C181JB8NNWC is strictly based on the following allowed parameters:

Critical Matching Parameters:

Capacitance value: 180 pF (exact match required)
Temperature coefficient: C0G/NP0 (interchangeable designations for same stability class)
Package/Case: 0603 (1608 Metric) footprint (PCB layout compatibility)
Mounting type: Surface Mount MLCC (assembly process compatibility)
Voltage rating: Minimum 50V (equal or higher acceptable)
Tolerance: ±5% baseline (±1% represents enhanced specification, acceptable as upgrade)

Acceptable Variation Parameters:

Manufacturer: Different manufacturers permitted if all critical parameters match
Packaging format: Tape & Reel (TR), Cut Tape (CT), or bulk formats are interchangeable for component selection
Product status: Active preferred; Last Time Buy acceptable; Obsolete requires end-of-life planning
Certifications: AEC-Q200 automotive rating is optional enhancement, not required for general-purpose applications

Non-Substitutable Parameters:

Operating temperature range exceeding -55°C to 125°C does not disqualify parts (higher ranges acceptable)
Thickness variations within 0.034" to 0.035" are acceptable (within manufacturing tolerance)

Engineering Selection Recommendations

Direct Substitutes (50V, ±5% Tolerance):

CL10C181JB81PND (Samsung Electro-Mechanics) serves as the primary upgrade path from CL10C181JB8NNWC, offering identical electrical specifications with Tape & Reel packaging and significantly higher inventory (77,559 units). Both components maintain Active product status and ROHS3 compliance.

C0603C181J5GAC7867 (KEMET) and KGM15ACG1H181JT (KYOCERA AVX) provide functionally equivalent alternatives with 65,032 and 64,203 units in stock respectively. All three alternatives maintain 50V rating, ±5% tolerance, C0G/NP0 temperature coefficient, and 0603 package compatibility.

VJ0603A181JXACW1BC (Vishay Vitramon) represents a fourth equivalent option with 3,989 units available, suitable when supplier diversification is required.

Enhanced Specification Substitutes (±1% Tolerance):

C0603C181F5GAC7867 (KEMET) upgrades tolerance from ±5% to ±1% while maintaining 50V rating and 0603 package. This component is appropriate for applications requiring tighter capacitance control. Inventory of 9,754 units supports production requirements.

Higher Voltage Substitutes (100V Rating):

C0603C181F1GAC7867 (KEMET) and C0603C181J1GAC7867 (KEMET) both provide 100V ratings with ±1% and ±5% tolerances respectively. These components are suitable for designs requiring voltage margin above the 50V minimum specification. Both maintain Active status and adequate inventory levels (14,994 and 8,632 units).

Obsolete/Last Time Buy Considerations:

C1608NP01H181J080AA (TDK Corporation) carries Last Time Buy status with 2,776 units available. This component matches all critical parameters but requires end-of-life planning for long-term production.

CGJ3E2C0G2A181J080AA and CGJ3E3C0G2D181J080AA (TDK Corporation) are classified Obsolete with 100V and 200V ratings respectively. These components should not be selected for new designs due to discontinued status.

Frequently Asked Questions (FAQ)

Q: Can CL10C181JB8NNWC be replaced with a higher voltage-rated capacitor such as C0603C181J1GAC7867 (100V)?

A: Yes. The 100V-rated C0603C181J1GAC7867 is a valid substitute. Higher voltage ratings provide additional safety margin and do not compromise circuit performance when the original 50V specification is met. The component maintains identical 180 pF capacitance, ±5% tolerance, C0G/NP0 temperature coefficient, and 0603 package footprint.

Q: What is the difference between Tape & Reel and bulk packaging formats?

A: Packaging format affects supply chain logistics and assembly automation compatibility. Tape & Reel (TR) format is optimized for high-volume automated pick-and-place assembly. Bulk format is suitable for manual assembly or lower-volume production. Both formats contain identical components; selection depends on manufacturing process requirements, not electrical performance.

Q: Is the ±1% tolerance upgrade from C0603C181F5GAC7867 necessary?

A: Tolerance upgrade is application-dependent. The original CL10C181JB8NNWC specifies ±5% tolerance. Upgrade to ±1% tolerance (C0603C181F5GAC7867) is appropriate only when circuit design requires tighter capacitance control. For general-purpose applications, ±5% tolerance substitutes are functionally equivalent.

Q: Why is C1608NP01H181J080AA marked as Last Time Buy?

A: Last Time Buy status indicates the manufacturer has discontinued production and existing inventory represents the final available supply. This component remains electrically equivalent to CL10C181JB8NNWC but should not be selected for designs requiring long-term component availability. Active-status alternatives are recommended for new designs.

Q: Are TDK CGJ series parts (100V and 200V) suitable replacements?

A: CGJ3E2C0G2A181J080AA (100V) and CGJ3E3C0G2D181J080AA (200V) are electrically compatible but carry Obsolete product status. These components should not be used in new designs. Active-status alternatives with equivalent or higher voltage ratings are available from KEMET, KYOCERA AVX, Vishay Vitramon, and Samsung Electro-Mechanics.

Q: What does C0G/NP0 temperature coefficient mean for substitution purposes?

A: C0G and NP0 designations refer to identical temperature stability classifications. These terms are manufacturer-specific nomenclature for the same dielectric material class. Components specified as either C0G or NP0 are interchangeable for substitution purposes. Both maintain capacitance stability across the -55°C to 125°C operating range.

Q: Can CL10C181JB8NNWC be substituted with parts from different manufacturers?

A: Yes. All listed substitute parts from KEMET, TDK Corporation, KYOCERA AVX, and Vishay Vitramon meet the critical electrical and mechanical parameters. Manufacturer selection depends on supply availability, pricing, and qualification requirements. All substitutes maintain ROHS3 compliance and MSL 1 rating.

Q: What inventory levels should influence substitute part selection?

A: CL10C181JB81PND (77,559 units) and C0603C181J5GAC7867 (65,032 units) offer the highest inventory availability. KGM15ACG1H181JT (64,203 units) and C0603C181F1GAC7867 (14,994 units) provide substantial stock. Selection should prioritize Active-status parts with inventory sufficient for production timelines and supply chain risk mitigation.
