Key Parameters

Substitute Part Grouping Explanation

Substitution of the MC12FD620F-TF is permissible when the following parameters remain constant or within acceptable engineering limits:

Fixed Parameters (No Variation Allowed):

• Capacitance value: 62 pF
• Voltage rating: 500 V
• Dielectric material: Mica
• Package / Case: 1210 (3225 Metric)
• Mounting type: Surface Mount
• Operating temperature range: -55°C ~ 125°C
• Physical dimensions: 0.126" L x 0.098" W (3.20mm x 2.50mm)
• Height seated (max): 0.079" (2.00mm)

Variable Parameters (Substitution Allowed Within Limits):

• Tolerance: ±1% (main part) to ±5% (substitute part) — substitution permitted when tolerance relaxation is acceptable for the application
• Packaging format: Bulk (substitute) versus standard (main part)

The MC12FD620J-F qualifies as a substitute because it maintains all fixed parameters while only the capacitance tolerance specification differs.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection (MC12FD620F-TF): The MC12FD620F-TF is the primary component choice when capacitance tolerance of ±1% is required for the application. This part maintains Active product status with full RoHS3 compliance and REACH unaffected designation. The ±1% tolerance specification provides tighter capacitance accuracy for precision RF circuits.

Substitute Selection (MC12FD620J-F): The MC12FD620J-F is a valid substitute when the application tolerates a ±5% capacitance tolerance. This part is also Active in product status with identical RoHS3 compliance and REACH unaffected designation. The substitute maintains all electrical performance characteristics (500 V rating, mica dielectric, RF/High Q/Low Loss features) and mechanical compatibility (1210 package, surface mount, identical dimensions). The MC12FD620J-F is available in Bulk packaging format with 1188 units in stock.

Compliance Verification: Both parts satisfy ROHS3 compliance requirements and are REACH unaffected. Both maintain Moisture Sensitivity Level 1 (Unlimited), indicating no special moisture handling is required during storage or assembly.

Frequently Asked Questions (FAQ)

Q: Can MC12FD620J-F replace MC12FD620F-TF in all applications?

A: The MC12FD620J-F can replace the MC12FD620F-TF only when the application circuit design accepts a ±5% capacitance tolerance. If the circuit requires ±1% tolerance accuracy, the MC12FD620F-TF must be used. Both parts are electrically and mechanically compatible in all other respects.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both the MC12FD620F-TF and MC12FD620J-F share identical dimensions: 0.126" L x 0.098" W (3.20mm x 2.50mm) with a maximum seated height of 0.079" (2.00mm). Both use the 1210 (3225 Metric) package format and are surface mount components. PCB footprints and assembly processes are interchangeable.

Q: What is the difference between these two parts?

A: The only electrical difference is capacitance tolerance. The MC12FD620F-TF specifies ±1% tolerance, while the MC12FD620J-F specifies ±5% tolerance. All other parameters—capacitance value (62 pF), voltage rating (500 V), dielectric material (mica), operating temperature range (-55°C ~ 125°C), and RF characteristics (High Q, Low Loss)—are identical.

Q: Are both parts currently available?

A: Yes. The MC12FD620F-TF has 1006 units in stock, and the MC12FD620J-F has 1188 units in stock. Both parts maintain Active product status.

Q: Do these parts require special handling during assembly?

A: No. Both parts have Moisture Sensitivity Level 1 (Unlimited), which means they do not require special moisture control or baking procedures prior to soldering. Standard surface mount assembly processes apply.

Q: Are there any compliance or regulatory differences?

A: No. Both parts are ROHS3 compliant and REACH unaffected. They carry identical environmental and regulatory designations (ECCN: EAR99, HTSUS: 8532.29.0020).
