• Output Type: CMOS (identical)
• Supply Voltage: 3.3V (identical)
• Function: Enable/Disable (identical)
• Package / Case: 4-SMD, No Lead (identical)
• Operating Temperature Range: -40°C ~ 85°C (identical)
• Mounting Type: Surface Mount (identical)
• Physical Dimensions: 0.126" L x 0.098" W (3.20mm x 2.50mm) (identical)
• Current - Supply (Max): 13mA (identical)
• Current - Supply (Disable) (Max): 10µA (identical)
• RoHS Status: ROHS3 Compliant (identical)
• Moisture Sensitivity Level: 1 (Unlimited) (identical)

Allowed Variance:

• Frequency Stability: Main part ±25ppm; Substitute ±50ppm (within acceptable tolerance range for this oscillator category)

Parameter Comparison

Engineering Selection Recommendations

Both the ASE-33.000MHZ-L-R-T and ASE-33.000MHZ-L-C-T are Active status products from Abracon LLC with identical ROHS3 compliance, REACH status, and regulatory classifications. The parts are electrically and mechanically interchangeable for applications requiring a 33 MHz CMOS oscillator with 3.3V supply and enable/disable control in a 4-SMD, No Lead package. The frequency stability difference (±25ppm versus ±50ppm) is the only technical variance and must be evaluated against application-specific timing requirements. Both parts maintain identical thermal operating range, current consumption, and physical dimensions, ensuring direct PCB compatibility.

Frequently Asked Questions (FAQ)

Q: Can ASE-33.000MHZ-L-C-T replace ASE-33.000MHZ-L-R-T in existing designs?

A: Yes. Both parts are electrically and mechanically equivalent with identical package, pinout, voltage supply, frequency, output type, and operating temperature range. The frequency stability specification differs (±50ppm versus ±25ppm); applications must confirm this tolerance is acceptable.

Q: What is the difference between these two part numbers?

A: The primary difference is frequency stability. ASE-33.000MHZ-L-R-T specifies ±25ppm, while ASE-33.000MHZ-L-C-T specifies ±50ppm. All other electrical and mechanical parameters are identical.

Q: Are the physical dimensions identical?

A: Yes. Both parts measure 0.126" L x 0.098" W (3.20mm x 2.50mm) with a maximum seated height of 0.047" (1.20mm), ensuring identical PCB footprint and assembly compatibility.

Q: Do both parts support enable/disable functionality?

A: Yes. Both oscillators include enable/disable control at 3.3V supply voltage with identical maximum supply current (13mA) and disable current (10µA).

Q: Are both parts RoHS compliant?

A: Yes. Both ASE-33.000MHZ-L-R-T and ASE-33.000MHZ-L-C-T are ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited).
