Key Parameters

Substitute Part Grouping Explanation

Substitution of the FCA1206C334M is determined by strict equivalence across the following critical parameters:

• Capacitance Value: 0.33 µF (exact match required)
• Capacitance Tolerance: ±20% (exact match required)
• Voltage Rating - DC: 16V (minimum acceptable rating)
• Voltage Rating - AC: 12V (minimum acceptable rating)
• Dielectric Material: Acrylic, Metallized (material class equivalence)
• Package / Case: 1206 (3216 Metric) (physical and electrical footprint compatibility)
• Mounting Type: Surface Mount (assembly process compatibility)
• Operating Temperature Range: -40°C ~ 85°C (thermal performance envelope)
• RoHS Status: ROHS3 Compliant (regulatory compliance requirement)

The FCA1206C334M-H2 qualifies as a direct substitute based on identical electrical specifications, matching physical dimensions, and equivalent environmental ratings. The primary distinction is product status (active vs. obsolete) and packaging format (Tape & Reel vs. standard packaging).

Parameter Comparison

Engineering Selection Recommendations

The FCA1206C334M-H2 is the direct active equivalent for the obsolete FCA1206C334M. Selection of FCA1206C334M-H2 is supported by:

• Physical Compatibility: Matching 1206 package dimensions and solder pad termination enable direct PCB footprint compatibility without layout modifications.
• Environmental Compliance: Both parts maintain ROHS3 compliance and identical moisture sensitivity ratings, ensuring equivalent handling and storage requirements.
• Product Status: FCA1206C334M-H2 is active production status, providing supply continuity and long-term availability compared to the obsolete FCA1206C334M.
• Packaging Consideration: FCA1206C334M-H2 is supplied in Tape & Reel format, which is standard for high-volume surface mount assembly operations.

Frequently Asked Questions (FAQ)

Q: Can FCA1206C334M-H2 be used as a direct replacement for FCA1206C334M in existing designs?

A: Yes. The FCA1206C334M-H2 is electrically and mechanically equivalent. All critical parameters—capacitance, tolerance, voltage ratings, package dimensions, and operating temperature range—are identical. No circuit redesign or PCB layout modification is required.

Q: What is the difference between FCA1206C334M and FCA1206C334M-H2?

A: The primary differences are product status and packaging format. FCA1206C334M is obsolete and supplied in standard packaging. FCA1206C334M-H2 is active production status and supplied in Tape & Reel (TR) format. All electrical and mechanical specifications are identical.

Q: Does the Tape & Reel packaging of FCA1206C334M-H2 affect compatibility?

A: No. Tape & Reel is a standard packaging format for surface mount components and is compatible with automated pick-and-place assembly equipment. The component itself is identical; only the delivery format differs.

Q: Are there any compliance or certification differences between these parts?

A: No. Both parts are ROHS3 compliant, REACH unaffected, and carry identical moisture sensitivity levels (MSL 4, 72 Hours). Regulatory and environmental compliance is equivalent.

Q: What is the maximum seated height difference between these parts?

A: The seated height maximum differs by 0.01mm (FCA1206C334M: 1.19mm vs. FCA1206C334M-H2: 1.20mm). This difference is negligible for PCB assembly and does not affect component placement or clearance in standard applications.

Q: Can FCA1206C334M-H2 be used in applications requiring the exact obsolete part number?

A: FCA1206C334M-H2 is the direct active equivalent. For applications with strict part number requirements, engineering documentation should be updated to reflect the active equivalent. Electrical and mechanical performance is identical.
