Substitute Part Grouping Explanation

Substitution for the 416F30033CAT is determined by the following critical parameters that must remain constant across all equivalent parts:

Frequency: 30 MHz (exact match required)
Frequency Stability: ±30ppm (exact match required)
ESR: 80 Ohms (exact match required)
Operating Mode: Fundamental (exact match required)
Operating Temperature Range: -20°C to 70°C (exact match required)
Package / Case: 4-SMD, No Lead (exact match required)
Physical Dimensions: 0.063" L x 0.047" W, 0.018" max height (exact match required)

The substitute parts listed below maintain all critical electrical and mechanical parameters. The primary variation among substitutes is the load capacitance specification, which is a design parameter that must be selected based on the specific circuit application and PCB layout characteristics.

Engineering Selection Recommendations

416F30033CAR is the parametric equivalent to the 416F30033CAT. Both parts share identical electrical specifications including 10pF load capacitance, 80 Ohms ESR, and ±30ppm frequency stability. The 416F30033CAR is currently active in production and available in Tape & Reel packaging, making it the direct replacement for discontinued stock.

416F30033CKR (8pF load capacitance) and 416F30033CLR (12pF load capacitance) are load capacitance variants within the same 416 series. These parts maintain all other electrical and mechanical specifications but differ in load capacitance. Selection between these variants depends on the specific circuit design requirements and PCB layout characteristics that determine the optimal load capacitance for frequency stability.

All substitute parts maintain ROHS3 compliance, MSL 1 rating, and identical physical dimensions, ensuring compatibility with existing PCB layouts and assembly processes.

Frequently Asked Questions (FAQ)

Q: Can I substitute 416F30033CKR or 416F30033CLR for the 416F30033CAT?

A: These parts are load capacitance variants. The 416F30033CKR has 8pF load capacitance while the 416F30033CLR has 12pF. Substitution is possible only if your circuit design accommodates the different load capacitance value. The load capacitance specification must match the circuit's total capacitive load for proper frequency accuracy.

Q: What is the difference between the main part and 416F30033CAR?

A: The 416F30033CAR is a parametric equivalent with identical electrical and mechanical specifications. The primary difference is product status: 416F30033CAT is discontinued while 416F30033CAR is active. The 416F30033CAR is available in Tape & Reel packaging versus bulk packaging for the main part.

Q: Are all substitute parts RoHS compliant?

A: Yes. All listed substitute parts are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity level, matching the compliance profile of the 416F30033CAT.

Q: Do the substitute parts fit the same PCB footprint?

A: Yes. All substitute parts share identical physical dimensions (0.063" L x 0.047" W, 0.018" max height) and 4-SMD, No Lead package configuration, ensuring direct PCB compatibility.

Q: Which substitute should I select for new designs?

A: For new designs requiring the 10pF load capacitance specification, use 416F30033CAR. For designs requiring different load capacitance values, select 416F30033CKR (8pF) or 416F30033CLR (12pF) based on circuit requirements.
