Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MMWA6P47K-F is determined by strict electrical and mechanical parameter matching within the following constraints:

Critical Matching Parameters:

• Capacitance value: 0.47 µF (exact match required)
• DC voltage rating: minimum 630V
• Dielectric material: Polyester, Metallized
• Tolerance: ±10%
• Operating temperature range: -55°C ~ 125°C
• Mounting type: Through Hole
• Package type: Axial
• Termination type: PC Pins

The substitute part 150474K630RF satisfies all critical electrical parameters while maintaining equivalent functional characteristics. Physical dimensions may vary within acceptable Through Hole assembly tolerances for PCB mounting applications.

Parameter Comparison

Engineering Selection Recommendations

Both MMWA6P47K-F and 150474K630RF maintain Active product status with full ROHS3 compliance and REACH Unaffected certification. Selection between these components should be based on PCB layout constraints and available inventory. The dimensional difference reflects design variations within the CDE film capacitor product line while maintaining electrical equivalency. Both components satisfy identical electrical specifications and regulatory requirements, making either suitable for applications requiring 0.47 µF, 630V axial film capacitors with polyester metallized dielectric.

Frequently Asked Questions (FAQ)

Q: Can 150474K630RF directly replace MMWA6P47K-F in existing PCBs? A: Direct substitution is electrically valid. Physical dimensions differ: 150474K630RF has a larger diameter (0.591" vs 0.469") and shorter length (1.299" vs 1.748"). PCB hole spacing and clearance verification is required before implementation.

Q: Are there voltage derating considerations between these parts? A: Both parts maintain identical 630V DC ratings and -55°C ~ 125°C operating temperature ranges. The AC voltage rating difference (250V vs 220V) does not affect DC circuit applications.

Q: What substitution constraints apply to these parts? A: Substitution is valid exclusively for applications requiring 0.47 µF capacitance at ±10% tolerance with 630V DC minimum rating. Dielectric material (Polyester, Metallized), mounting type (Through Hole), and termination type (PC Pins) must match application requirements.

Q: Do compliance certifications affect component selection? A: Both components carry identical ROHS3 Compliant, REACH Unaffected, and EAR99 ECCN designations. No compliance-based differentiation exists between these parts.

Q: What inventory advantages exist between these options? A: 150474K630RF maintains higher stock levels (1884 Pcs) compared to MMWA6P47K-F (934 Pcs). Packaging format differs: MMWA6P47K-F utilizes standard packaging while 150474K630RF ships in Bulk format.
