Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SA051C331KAR is determined by the following critical parameters:

• Capacitance value: 330 pF (exact match required)
• Tolerance: ±10% (exact match required)
• Voltage rating: 100V (exact match required)
• Temperature coefficient: X7R (exact match required)
• Operating temperature range: -55°C to 125°C (exact match required)
• Mounting type: Through Hole (exact match required)
• Package type: Axial (exact match required)
• Lead style: Straight (exact match required)

The identified substitute part A331K15X7RH5TAA meets all critical electrical and mechanical parameters. Physical dimensions vary within acceptable tolerances for through-hole axial mounting applications.

Parameter Comparison

Engineering Selection Recommendations

Both the SA051C331KAR and A331K15X7RH5TAA are active production components with ROHS3 compliance and REACH unaffected status, making them suitable for applications requiring regulatory compliance. Selection between these parts should be based on:

• PCB layout constraints: The SA051C331KAR has a smaller physical footprint (2.30mm diameter vs. 2.50mm), while the A331K15X7RH5TAA is slightly longer (3.80mm vs. 3.00mm).
• Supply chain availability: The A331K15X7RH5TAA currently has higher inventory (4275 units) compared to the SA051C331KAR (1021 units).
• Packaging format: SA051C331KAR is supplied in Tape & Reel format; A331K15X7RH5TAA is supplied in Cut Tape format.

Both parts satisfy identical electrical specifications and operating conditions.

Frequently Asked Questions (FAQ)

Q: Can A331K15X7RH5TAA be used as a direct replacement for SA051C331KAR?

A: Yes. Both parts have identical electrical specifications: 330 pF capacitance, ±10% tolerance, 100V rating, X7R temperature coefficient, and -55°C to 125°C operating range. Physical dimensions differ slightly but remain compatible with standard through-hole axial mounting.

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

A: The SA051C331KAR measures 0.091" diameter x 0.118" length (2.30mm x 3.00mm). The A331K15X7RH5TAA measures 0.098" diameter x 0.150" length (2.50mm x 3.80mm). These differences may affect PCB layout in space-constrained applications.

Q: Are both parts RoHS compliant?

A: Yes. Both SA051C331KAR and A331K15X7RH5TAA are ROHS3 compliant and REACH unaffected.

Q: What packaging formats are available?

A: SA051C331KAR is supplied in Tape & Reel (TR) format. A331K15X7RH5TAA is supplied in Cut Tape (CT) format. Packaging selection depends on assembly process requirements and order quantities.

Q: Are there any temperature or voltage derating considerations?

A: Both parts operate identically across the -55°C to 125°C temperature range with a 100V rated voltage. No derating differences exist between these components.
