Key Parameters

Substitute Part Grouping Explanation

Substitution of the MM033C104KCZ2A is determined by strict equivalence in the following parameters:

• Capacitance Value: 0.1 µF (exact match required)
• Tolerance: ±10% (exact match required)
• Temperature Coefficient: X7R (exact match required)
• Package / Case: 0603 (1608 Metric) (exact match required)
• Mounting Type: Surface Mount, MLCC (exact match required)
• Operating Temperature Range: -55°C ~ 125°C (exact match required)

The substitute part MM035C104KCZ2A meets all these criteria. The voltage rating increase from 25V to 50V represents an upgrade that maintains backward compatibility, as the higher voltage rating does not compromise performance in circuits designed for 25V operation.

Parameter Comparison

Engineering Selection Recommendations

The MM035C104KCZ2A is a direct functional substitute for the MM033C104KCZ2A. Both parts are manufactured by KYOCERA AVX and share identical electrical specifications for capacitance, tolerance, temperature coefficient, and operating temperature range. Both maintain identical physical dimensions and mounting characteristics for 0603 surface mount applications.

The MM035C104KCZ2A offers the advantage of active product status with higher inventory availability (7005 Pcs in stock versus 1155 Pcs for the discontinued part). The increased voltage rating of 50V provides additional design margin without affecting performance in 25V-rated circuits. Both parts maintain ROHS3 compliance and MSL 1 rating, ensuring compatibility with standard manufacturing and storage requirements.

Frequently Asked Questions (FAQ)

Q: Can MM035C104KCZ2A replace MM033C104KCZ2A in existing designs?

A: Yes. The MM035C104KCZ2A is electrically and mechanically equivalent to the MM033C104KCZ2A. Identical capacitance (0.1 µF), tolerance (±10%), temperature coefficient (X7R), package (0603), and operating temperature range (-55°C ~ 125°C) ensure direct substitution. The higher voltage rating (50V vs 25V) does not compromise performance in circuits designed for 25V operation.

Q: Are there physical compatibility concerns with the substitute part?

A: No. Both parts share identical dimensions (0.063" L x 0.032" W / 1.60mm x 0.81mm) and maximum thickness (0.029" / 0.74mm). PCB footprints and assembly processes remain unchanged.

Q: What is the difference in packaging between these parts?

A: The MM033C104KCZ2A is supplied in Cut Tape (CT) & Digi-Reel® packaging, while the MM035C104KCZ2A is supplied in Tape & Reel (TR) packaging. Packaging format does not affect component performance or compatibility.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the MM033C104KCZ2A and MM035C104KCZ2A are ROHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity rating. Compliance profiles are identical.

Q: Why is the substitute part rated for higher voltage?

A: The MM035C104KCZ2A is rated for 50V compared to the 25V rating of the MM033C104KCZ2A. This represents a design upgrade within the same product series. Higher voltage rating provides additional safety margin and does not affect electrical performance in lower-voltage applications.
