Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 167333K100A-F are qualified based on electrical and mechanical parameter equivalence. The following criteria determine substitution validity:

Electrical Parameters (Critical):

• Capacitance value: 0.033 µF
• Capacitance tolerance: ±10%
• Voltage rating - DC: 100V minimum
• Voltage rating - AC: 63V minimum
• Operating temperature range: -55°C to 125°C minimum
• Dielectric material: Polyester, Metallized composition

Mechanical Parameters (Critical):

• Mounting type: Through Hole
• Package configuration: Radial
• Termination style: PC Pins

Compliance Parameters:

• RoHS3 compliance status
• REACH compliance status

The substitute parts B32529C1333K189 and B32529C1333K289, both manufactured by EPCOS - TDK Electronics, meet all electrical and mechanical equivalence criteria. Both parts are actively produced, ROHS3 compliant, and feature identical electrical specifications. Physical dimensions differ slightly, which may impact board layout considerations in space-constrained applications.

Parameter Comparison

Engineering Selection Recommendations

All three parts—167333K100A-F, B32529C1333K189, and B32529C1333K289—are actively produced and maintain full ROHS3 and REACH compliance. Electrical specifications are identical across all three components, ensuring functional equivalence in circuit applications.

The primary distinction between the CDE 167333K100A-F and the EPCOS - TDK alternatives lies in physical dimensions and lead spacing. The CDE part features larger overall dimensions (10.50mm x 3.50mm) with 7.50mm lead spacing, while both EPCOS - TDK substitutes are more compact (7.30mm x 2.50mm) with 5.00mm lead spacing. This dimensional difference is significant for printed circuit board layout and should be evaluated against available board space and existing hole patterns.

The EPCOS - TDK B32529C1333K189 and B32529C1333K289 parts carry AEC-Q200 automotive qualification ratings, indicating suitability for automotive and EMI/RFI suppression applications. The CDE 167333K100A-F is designated for general-purpose applications. Selection between substitute parts should account for application-specific requirements and board design constraints.

Frequently Asked Questions (FAQ)

Q: Can B32529C1333K189 and B32529C1333K289 be used interchangeably with 167333K100A-F?

A: Yes, from an electrical standpoint. Both EPCOS - TDK parts are electrically equivalent, meeting identical capacitance, voltage, tolerance, and temperature specifications. However, physical dimensions and lead spacing differ, requiring board layout verification before substitution.

Q: What is the difference between B32529C1333K189 and B32529C1333K289?

A: Both parts are electrically and mechanically identical. The difference lies in packaging format: B32529C1333K189 is supplied in Cut Tape (CT) packaging with 56,412 pieces in stock, while B32529C1333K289 is also supplied in Cut Tape (CT) packaging with 12,793 pieces in stock. Electrical specifications, dimensions, and performance characteristics are identical.

Q: Will the smaller EPCOS - TDK parts fit in existing PCB designs for the CDE 167333K100A-F?

A: The EPCOS - TDK substitutes have different lead spacing (5.00mm versus 7.50mm) and smaller overall dimensions. Existing PCB hole patterns designed for the CDE part will not accommodate the EPCOS - TDK alternatives without board redesign or adapter solutions.

Q: Are there temperature or voltage derating considerations when substituting these parts?

A: No. All three parts operate identically across the -55°C to 125°C temperature range with 100V DC and 63V AC ratings. No derating adjustments are required for equivalent substitution.

Q: What packaging options are available for these parts?

A: The CDE 167333K100A-F is supplied in Bulk packaging. Both EPCOS - TDK substitutes (B32529C1333K189 and B32529C1333K289) are supplied in Cut Tape (CT) packaging, which may affect procurement workflows and handling procedures.

Q: Are all three parts RoHS and REACH compliant?

A: Yes. The 167333K100A-F, B32529C1333K189, and B32529C1333K289 are all ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.
