Substitute Part Grouping Explanation

Substitution eligibility for the 942C8P22K is determined by strict equivalence across the following critical parameters:

• Capacitance: 0.22 µF (exact match required)
• Tolerance: ±10% (exact match required)
• Voltage Rating - DC: 850V (minimum acceptable value)
• Voltage Rating - AC: 360V (minimum acceptable value)
• Dielectric Material: Polypropylene (PP), Metallized (exact match required)
• ESR: 7 mOhms (exact match required)
• Operating Temperature Range: -55°C to 105°C (exact match required)
• Mounting Type: Through Hole (exact match required)
• Package / Case: Axial (exact match required)
• Size / Dimension: 0.709" Dia x 1.339" L (exact match required)
• Termination: PC Pins (exact match required)

The 942C8P22K-F qualifies as a direct substitute due to identical electrical and mechanical specifications. The primary distinction is packaging format and product status.

Parameter Comparison

Engineering Selection Recommendations

The 942C8P22K-F is the recommended substitute for the obsolete 942C8P22K due to:

1. Product Status Alignment: The 942C8P22K-F is currently in active production status, ensuring continued component availability and supply chain reliability.

2. Compliance Enhancement: The 942C8P22K-F meets ROHS3 compliance requirements, whereas the original part is RoHS non-compliant. This compliance improvement addresses modern manufacturing and environmental standards.

3. Electrical and Mechanical Equivalence: All critical electrical parameters (capacitance, voltage rating, dielectric material, ESR, temperature range) and mechanical specifications (mounting type, package, dimensions, termination) are identical.

4. Performance Parity: Both components are rated for identical high pulse and DV/DT applications, confirming functional interchangeability within circuit designs.

Frequently Asked Questions (FAQ)

Q1: Can 942C8P22K-F directly replace 942C8P22K in existing circuit designs?

Yes. The 942C8P22K-F is electrically and mechanically equivalent. All performance characteristics, voltage ratings, capacitance values, and operating parameters match the original specification. Physical dimensions and mounting interfaces are identical, permitting direct substitution without circuit modification.

Q2: What is the difference between 942C8P22K and 942C8P22K-F?

The primary differences are product status and compliance certification. The 942C8P22K is obsolete and RoHS non-compliant. The 942C8P22K-F is an active production component that meets ROHS3 compliance standards. Packaging format differs (bulk versus standard), but electrical and mechanical specifications are identical.

Q3: Are there inventory considerations when selecting between these parts?

The 942C8P22K has 878 pieces in stock, while the 942C8P22K-F has 959 pieces available. For long-term procurement, the active status of 942C8P22K-F ensures sustained availability and reduces obsolescence risk.

Q4: Does the packaging difference affect circuit board assembly?

No. Packaging format (bulk versus standard) applies only to distribution and handling. Both parts use identical axial through-hole mounting with PC pin termination and are functionally equivalent in assembly operations.

Q5: Can this capacitor be used in automotive or high-reliability applications?

Selection for automotive or high-reliability applications depends on specific circuit requirements and compliance certifications beyond the provided parameters. Consult detailed application notes and regulatory documentation for your specific use case.

Q6: What is the moisture sensitivity classification of these capacitors?

Both 942C8P22K and 942C8P22K-F carry MSL (Moisture Sensitivity Level) 1 classification, indicating unlimited shelf life under standard storage conditions without moisture-sensitive component handling requirements.
