Substitute Part Grouping Explanation

Substitution eligibility for the ECJ-2VF1H333Z is determined by strict equivalence across the following parameters:

• Capacitance value: 0.033 µF (exact match required)
• Tolerance: -20%, +80% (exact match required)
• Voltage rating: 50V (minimum; higher ratings acceptable)
• Temperature coefficient: Y5V (F) (exact match required)
• Operating temperature range: -30°C ~ 85°C (minimum; wider ranges acceptable)
• Package: 0805 (2012 Metric) (exact match required)
• Mounting type: Surface Mount, MLCC (exact match required)
• Moisture sensitivity: MSL 1 (Unlimited) (exact match required)

The identified substitute parts meet all critical electrical and mechanical parameters. Both alternatives are from active product lines, providing improved long-term availability compared to the obsolete ECJ-2VF1H333Z.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts are functionally equivalent to the ECJ-2VF1H333Z and meet all specified electrical and mechanical requirements. Selection between alternatives should be based on the following factors:

C0805C333Z5VAC7800 (KEMET): Active product status with ROHS3 compliance and REACH unaffected certification. Available in Tape & Reel packaging. Maximum thickness of 0.035" (0.88mm) is within acceptable tolerance for standard PCB assembly processes.

CL21F333ZBANNNC (Samsung Electro-Mechanics): Active product status with ROHS3 compliance and REACH unaffected certification. Maximum thickness of 0.030" (0.75mm) provides closer dimensional match to the original part. Packaging format not specified in available data.

Both parts carry identical electrical specifications and operating parameters. The choice between them may be influenced by existing supply chain relationships, packaging requirements, or specific PCB assembly constraints related to component height.

Frequently Asked Questions (FAQ)

Q: Can C0805C333Z5VAC7800 or CL21F333ZBANNNC be used as direct replacements for ECJ-2VF1H333Z?

A: Yes. Both parts are electrically and mechanically equivalent. They share identical capacitance (0.033 µF), tolerance (-20%, +80%), voltage rating (50V), temperature coefficient (Y5V), operating temperature range (-30°C ~ 85°C), and package format (0805 / 2012 Metric). All three parts are surface mount MLCCs with MSL 1 rating.

Q: What is the significance of the thickness difference between the three parts?

A: The original ECJ-2VF1H333Z has a maximum thickness of 0.028" (0.70mm), while the KEMET substitute is 0.035" (0.88mm) and the Samsung substitute is 0.030" (0.75mm). All values remain within standard PCB assembly tolerances for 0805 packages. Thickness differences do not affect electrical performance or standard reflow soldering processes.

Q: Why is the ECJ-2VF1H333Z classified as obsolete?

A: Obsolete status indicates the part is no longer manufactured by Panasonic Electronic Components. The identified substitutes from KEMET and Samsung Electro-Mechanics are active products, ensuring continued availability for new designs and ongoing production support.

Q: Are there compliance differences between the original and substitute parts?

A: The substitute parts carry explicit ROHS3 compliance and REACH unaffected certifications. The original part's compliance status is not specified in available documentation. Both substitutes meet current regulatory requirements for electronic component manufacturing and distribution.

Q: Does packaging format affect substitution eligibility?

A: Packaging format (Tape & Reel versus bulk) does not affect electrical or mechanical compatibility. The KEMET part is specified as Tape & Reel; the Samsung part's packaging format is not detailed. Both are suitable for automated PCB assembly processes. Verify packaging availability with your supplier based on production volume requirements.
