Key Parameters

Substitute Part Grouping Explanation

Substitution for the 416F27022ILT is determined by the following critical electrical and mechanical parameters:

Electrical Parameters (Must Match):

• Frequency: 27 MHz
• Frequency Stability: ±20ppm
• Operating Mode: Fundamental
• ESR: 120 Ohms
• Operating Temperature Range: -40°C to 85°C

Mechanical Parameters (Must Match):

• Mounting Type: Surface Mount
• Package / Case: 4-SMD, No Lead
• Size / Dimension: 0.063" L x 0.047" W (1.60mm x 1.20mm)
• Height - Seated (Max): 0.018" (0.45mm)

Allowable Variation:

• Load Capacitance: 10pF or 12pF (circuit-dependent; verify load capacitance requirements in application schematic)

The 416F27022ILT has two identified substitutes within the CTS-Frequency Controls 416 series, both maintaining identical frequency, stability, ESR, temperature range, and physical dimensions. The primary difference between substitutes is load capacitance specification.

Parameter Comparison

Engineering Selection Recommendations

416F27022ILR (Parametric Equivalent): The 416F27022ILR is the direct parametric equivalent to the 416F27022ILT. Both parts maintain identical electrical specifications (27 MHz, ±20ppm stability, 120 Ohms ESR, 12pF load capacitance) and mechanical dimensions. The 416F27022ILR is currently in active production status with 881 pieces available in inventory. This part is supplied in Tape & Reel (TR) packaging format, suitable for automated assembly processes. ROHS3 compliance and MSL 1 rating are maintained.

416F27022IAR (Load Capacitance Variant): The 416F27022IAR shares all electrical and mechanical specifications with the 416F27022ILT except for load capacitance, which is specified at 10pF rather than 12pF. This part is suitable for substitution only when the application circuit is designed for 10pF load capacitance. The 416F27022IAR is in active production with 1101 pieces available in inventory and is supplied in Tape & Reel (TR) packaging. ROHS3 compliance and MSL 1 rating are maintained.

Both substitute parts are manufactured by CTS-Frequency Controls within the same 416 series product line, ensuring design continuity and manufacturing consistency.

Frequently Asked Questions (FAQ)

Q: Can the 416F27022ILR be used as a direct replacement for the 416F27022ILT?

A: Yes. The 416F27022ILR is a parametric equivalent with identical frequency (27 MHz), frequency stability (±20ppm), load capacitance (12pF), ESR (120 Ohms), operating temperature range (-40°C to 85°C), and physical dimensions. Both parts are 4-SMD, No Lead surface mount packages with 0.063" L x 0.047" W dimensions and 0.018" maximum seated height.

Q: What is the difference between the 416F27022ILT and 416F27022IAR?

A: The primary difference is load capacitance. The 416F27022ILT specifies 12pF load capacitance, while the 416F27022IAR specifies 10pF load capacitance. All other electrical parameters (frequency, stability, ESR, temperature range) and mechanical specifications (package, dimensions, height) are identical. Substitution is valid only if the application circuit is designed for 10pF load capacitance.

Q: Why does load capacitance matter in crystal selection?

A: Load capacitance is the capacitive load that the crystal oscillator circuit presents to the crystal element. The crystal is specified to operate at a particular frequency when connected to a circuit with a specific load capacitance value. Using a crystal with incorrect load capacitance can result in frequency deviation from the specified 27 MHz center frequency.

Q: What is the difference between bulk and Tape & Reel (TR) packaging?

A: The 416F27022ILT is supplied in bulk packaging, suitable for manual handling and small-quantity applications. The 416F27022ILR and 416F27022IAR are supplied in Tape & Reel (TR) format, which is standard for automated pick-and-place assembly processes in high-volume manufacturing. Both packaging formats contain the same electronic component.

Q: Are all three parts ROHS3 compliant?

A: Yes. The 416F27022ILT, 416F27022ILR, and 416F27022IAR are all ROHS3 compliant with Moisture Sensitivity Level (MSL) 1 rating, indicating unlimited shelf life under normal storage conditions.

Q: What is the current availability status of these parts?

A: The 416F27022ILT is discontinued at DiGi Electronics. The 416F27022ILR and 416F27022IAR are both in active production status with 881 and 1101 pieces in inventory, respectively.
