Substitute Part Grouping Explanation

Substitution eligibility for the 150334J100EB is determined by the following criteria:

Mandatory Matching Parameters:

• Capacitance value: 0.33 µF (exact match required)
• Voltage Rating - DC: 100V (substitute must equal or exceed)
• Dielectric Material: Polyester (metallized construction acceptable)
• Mounting Type: Through Hole
• Package / Case: Axial
• Termination: PC Pins
• Operating Temperature Range: -55°C to 125°C (substitute must cover this range)
• RoHS Status: ROHS3 Compliant

Acceptable Variation Parameters:

• Tolerance: ±5% to ±10% (wider tolerance acceptable for general-purpose applications)
• Voltage Rating - AC: 63V to 65V (minor variation acceptable if DC rating maintained)
• Physical dimensions: Variation acceptable provided axial form factor and through-hole compatibility maintained
• Product Status: Active substitutes preferred for obsolete parts

Both identified substitute parts (MMP1P33K-F and WMF1P33K-F) meet all mandatory matching criteria and are classified as active products from the same manufacturer.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (PCB Layout Compatibility Critical):

The MMP1P33K-F provides the closest dimensional compatibility to the 150334J100EB while maintaining all electrical specifications. Both parts share identical capacitance (0.33 µF), DC voltage rating (100V), operating temperature range (-55°C to 125°C), and dielectric material composition (polyester, metallized). The MMP1P33K-F is an active product with ROHS3 compliance and unlimited moisture sensitivity rating, making it suitable for immediate procurement and deployment in replacement applications where PCB hole spacing and component density are constrained.

For New Design Applications (Layout Flexibility Available):

The WMF1P33K-F offers an alternative with identical electrical core specifications (0.33 µF, 100V DC, -55°C to 125°C operating range) and active product status. This part features a longer axial length (1.185" vs. 0.650" for the original part) and polyester dielectric without specified metallization. The WMF1P33K-F is appropriate for applications where PCB layout permits increased component length and where the polyester dielectric meets circuit requirements.

Compliance and Regulatory Considerations:

Both substitute parts maintain ROHS3 compliance and REACH unaffected status, matching the regulatory profile of the obsolete 150334J100EB. Both substitutes carry MSL rating of 1 (unlimited), indicating no moisture sensitivity constraints for storage and handling.

Tolerance Consideration:

The 150334J100EB specifies ±5% tolerance, while both substitutes specify ±10% tolerance. For general-purpose applications, the wider tolerance of the substitute parts is acceptable. Applications requiring tighter capacitance tolerance should evaluate circuit sensitivity to the additional ±5% variation.

Frequently Asked Questions (FAQ)

Q: Can MMP1P33K-F and WMF1P33K-F be used interchangeably with 150334J100EB?

A: Both parts are electrically equivalent for the core specifications (0.33 µF, 100V DC, -55°C to 125°C). However, physical dimensions differ. MMP1P33K-F dimensions are 11.00mm x 6.00mm x 17.00mm; WMF1P33K-F dimensions are 10.50mm diameter x 30.10mm length; original part dimensions are 8.00mm diameter x 16.50mm length. PCB layout compatibility must be verified before substitution.

Q: What is the impact of ±10% tolerance on circuit performance compared to ±5%?

A: The tolerance specification defines the acceptable capacitance variation from the nominal 0.33 µF value. The original part allows ±0.0165 µF variation; substitute parts allow ±0.033 µF variation. Circuit performance impact depends on application requirements. General-purpose applications typically tolerate this wider tolerance range.

Q: Are both substitute parts suitable for high-temperature applications?

A: Yes. Both MMP1P33K-F and WMF1P33K-F maintain the same operating temperature range as the original part: -55°C to 125°C. No thermal performance degradation occurs with either substitute.

Q: What is the difference between metallized and non-metallized polyester dielectric?

A: The original 150334J100EB and MMP1P33K-F specify metallized polyester construction. The WMF1P33K-F specifies polyester without metallization specification. Metallized construction typically provides self-healing properties in case of dielectric breakdown. For general-purpose applications, both constructions are acceptable; applications requiring self-healing capability should prioritize the metallized option (MMP1P33K-F).

Q: Are there inventory considerations for selecting between MMP1P33K-F and WMF1P33K-F?

A: Current inventory levels are: MMP1P33K-F (959 pcs), WMF1P33K-F (2893 pcs). WMF1P33K-F offers significantly higher stock availability. For time-sensitive procurement, WMF1P33K-F may provide faster delivery; for applications with specific dimensional constraints, MMP1P33K-F may be preferred despite lower inventory.

Q: Do both substitute parts maintain RoHS3 compliance?

A: Yes. Both MMP1P33K-F and WMF1P33K-F are ROHS3 compliant and REACH unaffected, matching the regulatory status of the original 150334J100EB.
