Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MC22FD511G-F is determined by the following criteria:

Mandatory Match Parameters:

• Capacitance value: 510 pF (exact match required)
• Dielectric material: Mica (RF and high Q performance dependent)
• Package / Case: 2220 (5750 Metric) (PCB footprint compatibility)
• Mounting type: Surface Mount (assembly process compatibility)
• Voltage rating: 500 V minimum (electrical safety requirement)
• Operating temperature range: -55°C ~ 125°C minimum (thermal performance)

Allowable Variation Parameters:

• Tolerance: ±2% to ±5% (design margin dependent; wider tolerance acceptable if circuit design permits)
• RoHS and REACH compliance status (regulatory alignment)

The MC22FD511J-F qualifies as a substitute part because it maintains all mandatory match parameters while permitting tolerance relaxation from ±2% to ±5%, provided circuit design specifications allow this variation.

Parameter Comparison

Engineering Selection Recommendations

MC22FD511G-F (Primary Selection):

• Select when circuit design requires ±2% tolerance specification
• Active product status with established supply (771 pcs in stock)
• ROHS3 compliant and REACH unaffected
• Suitable for precision RF applications with tight capacitance tolerance requirements

MC22FD511J-F (Substitute Selection):

• Select when circuit design permits ±5% tolerance relaxation
• Higher inventory availability (1,333 pcs in stock)
• Active product status with identical regulatory compliance (ROHS3, REACH unaffected)
• Functionally equivalent for RF applications where tolerance margin exists
• Identical physical footprint, thermal range, and electrical performance characteristics

Both parts maintain Active product status, ROHS3 compliance, and REACH unaffected designation. Selection between these parts depends solely on tolerance requirements specified in the circuit design documentation.

Frequently Asked Questions (FAQ)

Q: Can MC22FD511J-F replace MC22FD511G-F in all applications?

A: MC22FD511J-F can replace MC22FD511G-F only when the circuit design specification permits ±5% capacitance tolerance. If the design requires ±2% tolerance, substitution is not acceptable. Review the circuit schematic and design documentation to confirm tolerance requirements.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both parts use the 2220 (5750 Metric) package with identical dimensions: 0.224" L x 0.197" W (5.70mm x 5.00mm) and maximum seated height of 0.079" (2.00mm). PCB footprints are interchangeable.

Q: Do both parts have the same operating temperature range?

A: Yes. Both MC22FD511G-F and MC22FD511J-F operate across -55°C to 125°C. Thermal performance is identical.

Q: What is the difference between these two parts?

A: The only difference is capacitance tolerance: MC22FD511G-F specifies ±2% tolerance, while MC22FD511J-F specifies ±5% tolerance. All other electrical, mechanical, and regulatory parameters are identical.

Q: Are both parts RoHS compliant?

A: Yes. Both MC22FD511G-F and MC22FD511J-F are ROHS3 compliant and REACH unaffected.

Q: Which part should I select if tolerance is not critical?

A: If circuit design permits ±5% tolerance, MC22FD511J-F is acceptable. Verify tolerance requirements in the design specification before making this determination.

Q: Are these parts suitable for RF applications?

A: Yes. Both parts feature RF, High Q, and Low Loss characteristics and are designed for RF circuit applications.
