Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 7W-33.333MBE-T is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Frequency: 33.333 MHz (exact match required)
• Output Type: CMOS
• Supply Voltage: 3.3V
• Function: Enable/Disable
• Frequency Stability: ±50ppm
• Operating Temperature Range: -40°C ~ 85°C
• Package Type: 4-SMD, No Lead
• Package Dimensions: 7.00mm x 5.00mm
• Mounting Type: Surface Mount
• Base Resonator: Crystal

Both identified substitute parts meet all mandatory matching parameters. Variations in current consumption, maximum seated height, and disable current specifications do not affect functional substitution within the defined electrical and mechanical constraints.

Parameter Comparison

Engineering Selection Recommendations

CPPC7L-A7BP-33.333TS (Cardinal Components Inc.)

This substitute part carries Active product status and holds ROHS3 compliance certification. The component meets all mandatory electrical and mechanical parameters. Maximum supply current is specified at 25mA, which exceeds the original 20mA specification. Maximum seated height is 1.90mm, representing a 0.48mm increase over the original part. This substitute is suitable for applications where the increased height and current specifications do not present physical or thermal constraints.

OCETGLJANF-33.333000 (Taitien)

This substitute part carries Active product status and holds ROHS3 compliance certification. The component meets all mandatory electrical and mechanical parameters. Maximum supply current is specified at 10mA, which is lower than the original 20mA specification. Maximum seated height is 1.50mm, representing a 0.08mm increase over the original part. This substitute is suitable for applications where lower power consumption is beneficial and physical space constraints are minimal.

Both substitute parts are suitable for direct replacement based on electrical equivalence and compliance certifications. Selection between the two substitutes depends on specific application requirements regarding current consumption and available PCB clearance.

Frequently Asked Questions (FAQ)

Q: Can the CPPC7L-A7BP-33.333TS be used as a direct replacement for the 7W-33.333MBE-T?

A: Yes. Both parts operate at 33.333 MHz with CMOS output, 3.3V supply, enable/disable function, ±50ppm frequency stability, and -40°C to 85°C temperature range. Both use identical 4-SMD, No Lead packaging with 7.00mm x 5.00mm dimensions. The CPPC7L-A7BP-33.333TS is electrically and mechanically equivalent.

Q: Can the OCETGLJANF-33.333000 be used as a direct replacement for the 7W-33.333MBE-T?

A: Yes. Both parts operate at 33.333 MHz with CMOS output, 3.3V supply, enable/disable function, ±50ppm frequency stability, and -40°C to 85°C temperature range. Both use identical 4-SMD, No Lead packaging with 7.00mm x 5.00mm dimensions. The OCETGLJANF-33.333000 is electrically and mechanically equivalent.

Q: What is the difference in current consumption between these parts?

A: The 7W-33.333MBE-T specifies 20mA maximum supply current. The CPPC7L-A7BP-33.333TS specifies 25mA maximum. The OCETGLJANF-33.333000 specifies 10mA maximum. Applications with strict power budgets should select the OCETGLJANF-33.333000. Applications with no power constraints can use either substitute.

Q: Are there height differences that affect PCB layout?

A: Yes. The 7W-33.333MBE-T has a maximum seated height of 1.42mm. The CPPC7L-A7BP-33.333TS measures 1.90mm maximum. The OCETGLJANF-33.333000 measures 1.50mm maximum. For designs with minimal vertical clearance, the OCETGLJANF-33.333000 is preferred. The CPPC7L-A7BP-33.333TS requires verification of available clearance above the component.

Q: Do all three parts have the same RoHS compliance status?

A: The 7W-33.333MBE-T is RoHS Compliant. Both substitutes are ROHS3 Compliant. ROHS3 represents an updated compliance standard. Both substitutes meet or exceed the original compliance requirement.

Q: What packaging formats are available for these parts?

A: The 7W-33.333MBE-T is supplied in Cut Tape (CT) packaging. The CPPC7L-A7BP-33.333TS and OCETGLJANF-33.333000 are supplied in Tape & Reel (TR) packaging. Tape & Reel format is standard for high-volume production and automated assembly processes.
