416F25035ILR Crystal Oscillator Equivalent & Substitute Parts

Part Overview

The 416F25035ILR is a 25 MHz fundamental mode crystal oscillator manufactured by CTS-Frequency Controls, designed for surface mount applications requiring precise frequency stability. This Active product operates across the industrial temperature range of -40°C to 85°C with a 12pF load capacitance and 120 Ohms equivalent series resistance. The component is packaged in a 4-SMD, No Lead configuration measuring 1.60mm × 1.20mm with a maximum seated height of 0.45mm. Substitute parts are identified when equivalent frequency, stability, tolerance, operating mode, temperature range, and package specifications can be maintained while accommodating minor variations in load capacitance and ESR within acceptable design margins.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 416F25035ILR is permissible when the following critical parameters remain constant or within acceptable engineering tolerances:

• Frequency: 25 MHz (exact match required)
• Frequency Tolerance: ±30ppm (exact match required)
• Frequency Stability: ±50ppm (exact match required)
• Operating Mode: Fundamental (exact match required)
• Operating Temperature Range: -40°C to 85°C (exact match required)
• Mounting Type: Surface Mount (exact match required)
• Package / Case: 4-SMD, No Lead (exact match required)
• Physical Dimensions: 1.60mm L × 1.20mm W (exact match required)

Secondary parameters that may vary within acceptable design margins:

• Load Capacitance: 10pF to 12pF (minor variation acceptable)
• ESR (Equivalent Series Resistance): 120 to 150 Ohms (minor variation acceptable)
• Height - Seated (Max): 0.40mm to 0.45mm (minor variation acceptable)

Parameter Comparison

Engineering Selection Recommendations

Both the 416F25035ILR and EB1216YA10-25.000M TR are Active products with ROHS3 compliance and MSL 1 rating, ensuring regulatory and environmental compatibility. The EB1216YA10-25.000M TR carries AEC-Q200 qualification, indicating automotive-grade reliability testing. Selection between these parts should be based on application-specific requirements regarding load capacitance tolerance and ESR specifications. The 2pF load capacitance difference and 30 Ohms ESR variation between parts are within typical crystal oscillator design margins and do not preclude substitution in most applications. The EB1216YA10-25.000M TR offers a lower seated height (0.40mm vs. 0.45mm), which may be advantageous in space-constrained designs.

Frequently Asked Questions (FAQ)

Q: Can the EB1216YA10-25.000M TR directly replace the 416F25035ILR?

A: Yes, the EB1216YA10-25.000M TR is a qualified substitute. Both parts share identical frequency (25 MHz), tolerance (±30ppm), stability (±50ppm), operating mode (Fundamental), temperature range (-40°C to 85°C), mounting type (Surface Mount), and package configuration (4-SMD, No Lead). The load capacitance difference (10pF vs. 12pF) and ESR variation (150 Ohms vs. 120 Ohms) are within acceptable engineering tolerances for most applications.

Q: What is the significance of the load capacitance difference?

A: Load capacitance affects the crystal's resonant frequency in the circuit. The 2pF difference between 12pF and 10pF may require minor circuit tuning adjustments. Circuit designers should verify that the substitute part's load capacitance is compatible with the oscillator circuit's design specifications.

Q: Does the ESR difference impact performance?

A: ESR (Equivalent Series Resistance) influences power consumption and frequency stability. The 30 Ohms difference (120 Ohms vs. 150 Ohms) represents a 25% increase. For most industrial applications, this variation remains within acceptable limits. Applications with stringent power or stability requirements should evaluate this parameter against design specifications.

Q: What advantage does the lower height of the EB1216YA10-25.000M TR provide?

A: The EB1216YA10-25.000M TR has a maximum seated height of 0.40mm compared to 0.45mm for the 416F25035ILR. This 0.05mm reduction may be beneficial in applications with strict PCB assembly height constraints or where multiple components must fit within limited vertical space.

Q: Are both parts suitable for automotive applications?

A: The EB1216YA10-25.000M TR carries AEC-Q200 qualification, indicating automotive-grade reliability testing. The 416F25035ILR does not list this qualification. For automotive applications, the EB1216YA10-25.000M TR is the preferred choice.

Q: What is the difference between packaging types (Tape & Reel vs. Cut Tape & Digi-Reel)?

A: Tape & Reel (TR) and Cut Tape (CT) & Digi-Reel® represent different supply formats for automated assembly. Both formats are compatible with standard pick-and-place equipment. Selection depends on production volume and assembly line configuration rather than component functionality.
