AC20070001 20 MHz CMOS Oscillator Equivalent & Substitute Parts

Part Overview

The AC20070001 is a 20 MHz XO (Standard) CMOS oscillator manufactured by TXC CORPORATION, designed for applications requiring a stable frequency reference with enable/disable functionality. This surface mount device operates at 3.3V supply voltage and is housed in a compact 4-SMD, No Lead package measuring 5.00mm x 3.20mm.

The part is currently Active in product status with 1058 pieces in stock. Substitute parts are identified to provide alternative sourcing options when the primary manufacturer part becomes unavailable, when inventory constraints exist, or when supply chain optimization is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AC20070001 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Frequency: 20 MHz (exact match required)
• Output Type: CMOS
• Supply Voltage: 3.3V
• Frequency Stability: ±50ppm
• Operating Temperature Range: -40°C ~ 85°C
• Function: Enable/Disable capability
• Package / Case: 4-SMD, No Lead
• Physical Dimensions: 5.00mm x 3.20mm footprint
• Base Resonator: Crystal-based XO

The substitute part SXO53C3A481-20.000M from Suntsu Electronics, Inc. meets all mandatory matching parameters and is therefore classified as a direct equivalent for the AC20070001.

Engineering Selection Recommendations

Primary Part Selection (AC20070001): The AC20070001 from TXC CORPORATION is the original specified component. It is Active in product status and RoHS Compliant. This part should be selected when TXC supply chain preference is established or when MSL 1 rating is a documented requirement.

Substitute Part Selection (SXO53C3A481-20.000M): The SXO53C3A481-20.000M from Suntsu Electronics, Inc. is a direct functional equivalent meeting all critical electrical and mechanical parameters. This part is Active in product status and ROHS3 Compliant. Selection of this substitute is appropriate when:

• TXC CORPORATION supply is constrained or unavailable
• Higher inventory availability is required (3733 pieces in stock versus 1058 pieces)
• Suntsu Electronics supply chain is preferred
• Maximum supply current specification (16mA) is documented in design requirements

Both parts are suitable for identical PCB layouts and circuit implementations. No design modifications are required when substituting between these parts.

Frequently Asked Questions (FAQ)

Q: Can the SXO53C3A481-20.000M be used as a direct replacement for the AC20070001 on existing PCBs?

A: Yes. Both parts share identical package specifications (4-SMD, No Lead), physical dimensions (5.00mm x 3.20mm x 1.40mm Max), and electrical characteristics (20 MHz, CMOS output, 3.3V supply, ±50ppm stability, -40°C ~ 85°C operating range, Enable/Disable function). No PCB layout modifications are required.

Q: What are the key differences between these two parts?

A: The parts differ in manufacturer (TXC versus Suntsu), series designation (AC versus SXO53C), and documentation completeness. The Suntsu part specifies maximum supply current at 16mA, while the TXC part does not provide this specification. The TXC part specifies MSL 1 rating; the Suntsu specification does not include this parameter. Both parts meet RoHS compliance standards.

Q: Are there any compatibility concerns when switching between these oscillators?

A: No compatibility concerns exist for electrical or mechanical integration. Both parts are crystal-based XO oscillators with identical frequency, output type, supply voltage, stability, temperature range, and enable/disable functionality. Footprint and height are identical.

Q: Which part should be selected for new designs?

A: Selection should be based on supply chain strategy and inventory availability. Both parts are Active and suitable for new designs. The Suntsu part offers higher current inventory (3733 pieces). The TXC part is the original specification. Consult supply chain and procurement requirements for final selection.

Q: Is there a performance difference between these oscillators?

A: No performance difference exists within the specified parameters. Both parts deliver 20 MHz frequency output with ±50ppm stability across the -40°C ~ 85°C operating range. Both support enable/disable control and operate from 3.3V supply.
