Substitute Part Grouping Explanation

Substitute parts for the MMP1P68K-F are identified based on strict electrical and mechanical equivalence. The substitution logic requires:

Mandatory Matching Parameters:

• Capacitance value: 0.68 µF (exact match)
• DC voltage rating: 100V minimum
• Dielectric material: Polyester, Metallized
• Mounting type: Through Hole, Axial
• Termination: PC Pins
• Operating temperature range: -55°C ~ 125°C or better
• RoHS compliance: ROHS3 Compliant

Acceptable Variations:

• Tolerance: ±5% is acceptable as a tighter specification than ±10%
• AC voltage rating: May vary within design margins
• Physical dimensions: Minor variations acceptable if mounting compatibility maintained
• Packaging format: Bulk or standard packaging acceptable

The substitute part 150684J100FC meets all mandatory parameters while offering improved tolerance specification (±5% versus ±10%), making it functionally equivalent for circuit applications.

Engineering Selection Recommendations

Primary Part: MMP1P68K-F

• Use when ±10% tolerance specification is acceptable for circuit design
• Preferred when MMP series continuity is required for production consistency
• 933 units currently available

Substitute Part: 150684J100FC

• Use when tighter ±5% tolerance improves circuit performance or meets design specifications
• Functionally equivalent across all critical electrical parameters
• Higher inventory availability (1180 units) supports supply chain continuity
• Both parts maintain identical RoHS3 compliance and REACH unaffected status

Both parts are manufactured by Cornell Dubilier Electronics and carry active product status. Selection between primary and substitute should be based on tolerance requirements and inventory availability for your specific application timeline.

Frequently Asked Questions (FAQ)

Q: Can 150684J100FC replace MMP1P68K-F in existing designs? A: Yes. Both parts share identical capacitance (0.68 µF), voltage rating (100V DC), dielectric material (polyester metallized), operating temperature range (-55°C ~ 125°C), and mounting configuration (through-hole axial). The substitute offers improved tolerance (±5% versus ±10%).

Q: What is the difference in physical size between these parts? A: MMP1P68K-F dimensions are 0.433" W × 0.256" T × 0.906" L (11.00mm × 6.50mm × 23.00mm). The 150684J100FC measures 0.335" diameter × 0.807" L (8.50mm × 20.50mm). The substitute is more compact. Verify PCB layout compatibility before substitution.

Q: Are both parts RoHS compliant? A: Yes. Both MMP1P68K-F and 150684J100FC are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements.

Q: What does the ±5% tolerance improvement mean for circuit performance? A: The 150684J100FC tolerance of ±5% provides tighter capacitance accuracy compared to the ±10% specification of MMP1P68K-F. This reduces capacitance variation across production batches, beneficial for precision filtering, timing, or frequency-dependent applications.

Q: Can I use these parts interchangeably in production? A: Both parts are suitable for through-hole PCB assembly with identical electrical performance at rated specifications. Verify mechanical fit given the dimensional differences, particularly lead spacing and component body diameter relative to your PCB hole layout.

Q: What is the moisture sensitivity level for both parts? A: Both parts carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.
