Equivalent & Substitute Parts for ECH-S1333JZ

Part Overview

The ECH-S1333JZ is a 0.033 µF film capacitor manufactured by Panasonic Electronic Components, rated for 100V DC operation with ±5% tolerance. This radial through-hole component utilizes polyphenylene sulfide (PPS) dielectric material and is designed for high-frequency and switching applications. The product is currently obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ECH-S1333JZ requires matching the following critical electrical parameters: capacitance value (0.033 µF), voltage rating (100V DC minimum), tolerance specification (±5%), and dielectric material (PPS). The identified substitute parts ECH-U1333GC9 and ECH-U1333JC9 maintain electrical equivalence through identical capacitance, voltage rating, and dielectric composition. However, these substitutes employ surface-mount technology (2416 package) rather than through-hole radial construction, representing a packaging transition rather than direct pin-compatible replacement. Both substitutes are active products with enhanced compliance certifications and superior temperature operating ranges (-55°C ~ 105°C).

Parameter Comparison

Engineering Selection Recommendations

ECH-U1333JC9 is the primary electrical equivalent, maintaining identical capacitance (0.033 µF), tolerance (±5%), and DC voltage rating (100V) as the obsolete ECH-S1333JZ. This substitute is an active product with ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for new designs and ongoing procurement. ECH-U1333GC9 offers superior tolerance (±2%) and equivalent electrical performance but requires tolerance specification verification against circuit requirements.

Both substitutes require circuit board redesign due to transition from through-hole radial to surface-mount 2416 package format. The substitutes operate across a narrower maximum temperature range (-55°C ~ 105°C) compared to the original part (-40°C ~ 125°C); applications requiring operation above 105°C require alternative component evaluation. Metallized-stacked dielectric construction in substitutes differs from the original film construction, maintaining PPS material properties while reducing physical dimensions.

Frequently Asked Questions (FAQ)

Q: Can ECH-U1333GC9 or ECH-U1333JC9 be used as direct pin-compatible replacements for ECH-S1333JZ?

A: No. The substitute parts employ surface-mount 2416 package technology, while the original uses through-hole radial construction. Direct socket substitution is not possible; circuit board redesign is required.

Q: What is the difference between ECH-U1333GC9 and ECH-U1333JC9?

A: Both parts are electrically equivalent with identical capacitance (0.033 µF) and voltage rating (100V DC). The primary difference is tolerance specification: ECH-U1333GC9 provides ±2% tolerance, while ECH-U1333JC9 maintains ±5% tolerance matching the original part. Component selection depends on circuit tolerance requirements.

Q: Are the substitute parts suitable for high-frequency and switching applications?

A: The substitute parts are specified for general-purpose applications. Original application classification (high-frequency, switching) should be verified against substitute performance characteristics before implementation.

Q: What compliance certifications apply to the substitute parts?

A: Both ECH-U1333GC9 and ECH-U1333JC9 are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component procurement.

Q: Do the substitute parts operate across the same temperature range as the original?

A: No. The original ECH-S1333JZ operates from -40°C to 125°C, while substitutes operate from -55°C to 105°C. Applications requiring operation above 105°C require alternative component selection.
