1812J0500104FCT Equivalent & Substitute Parts

Part Overview

The 1812J0500104FCT is a 0.1 µF ceramic capacitor manufactured by Knowles Syfer, rated for 50V with C0G/NP0 temperature coefficient and ±1% tolerance. This surface mount multilayer ceramic capacitor (MLCC) is designed for general purpose applications requiring stable capacitance across the operating temperature range of -55°C to 125°C. The part is currently active in production and ROHS3 compliant. Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are required due to inventory constraints, supply chain considerations, or design flexibility needs.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1812J0500104FCT is determined by strict equivalence across the following critical parameters:

• Capacitance value: 0.1 µF (exact match required)
• Tolerance: ±1% (exact match required)
• Voltage rating: 50V (exact match required)
• Temperature coefficient: C0G/NP0 (exact match required)
• Operating temperature range: -55°C to 125°C (exact match required)
• Package: 1812 (4532 Metric) (exact match required)
• Mounting type: Surface Mount, MLCC (exact match required)
• Moisture sensitivity level: 1 (Unlimited) (exact match required)
• Compliance: ROHS3 Compliant, REACH Unaffected (exact match required)

The substitute part C1812C104F5GAC7800 from KEMET meets all these criteria and is therefore electrically and mechanically interchangeable with the original part.

Parameter Comparison

Engineering Selection Recommendations

Both the 1812J0500104FCT and C1812C104F5GAC7800 are active production parts with identical electrical specifications and mechanical compatibility. Selection between these parts may be based on availability, lead time, or supply chain requirements. Both parts maintain ROHS3 compliance and REACH unaffected status, meeting regulatory requirements for industrial and commercial applications. The KEMET substitute exhibits a reduced maximum thickness (1.10mm versus 2.50mm), which may provide design flexibility in space-constrained applications while maintaining all electrical and thermal performance characteristics.

Frequently Asked Questions (FAQ)

Q: Can C1812C104F5GAC7800 be used as a direct replacement for 1812J0500104FCT?

A: Yes. Both parts share identical electrical specifications (0.1 µF, ±1%, 50V, C0G/NP0), operating temperature range (-55°C to 125°C), package dimensions (1812/4532 Metric), and compliance certifications (ROHS3, REACH Unaffected). They are electrically and mechanically interchangeable.

Q: Are there any physical differences between these parts?

A: The maximum thickness differs: the Knowles Syfer part is 0.098" (2.50mm) while the KEMET part is 0.043" (1.10mm). Both fit the 1812 package footprint and are compatible with standard PCB assembly processes.

Q: Do both parts have the same moisture sensitivity rating?

A: Yes. Both parts have Moisture Sensitivity Level 1 (Unlimited), indicating no special moisture handling requirements during storage or assembly.

Q: Are both parts currently in production?

A: Yes. Both the 1812J0500104FCT and C1812C104F5GAC7800 maintain active product status with current inventory availability.
