7W20000034 XTAL OSC XO 20.0000MHZ CMOS SMD Equivalent & Substitute Parts

Part Overview

The 7W20000034 is a 20 MHz crystal oscillator manufactured by TXC CORPORATION, designed for applications requiring a standard XO (Standard) CMOS oscillator with 3.3V supply and Enable/Disable functionality. This component operates across the industrial temperature range of -40°C to 85°C and is packaged in a 4-SMD, No Lead surface mount configuration.

The 7W20000034 has reached obsolete product status. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production requirements for legacy systems or redesign initiatives.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 7W20000034 are qualified based on strict electrical and mechanical parameter alignment. The following criteria determine substitution eligibility:

Electrical Parameters (Must Match):

• Frequency: 20 MHz
• Output Type: CMOS
• Supply Voltage: 3.3V
• Function: Enable/Disable
• Frequency Stability: ±50ppm
• Operating Temperature Range: -40°C ~ 85°C
• Base Resonator Type: Crystal

Mechanical Parameters (Must Match):

• Package Type: 4-SMD, No Lead
• Physical Dimensions: 0.276" L x 0.197" W (7.00mm x 5.00mm)
• Mounting Type: Surface Mount

All identified substitute parts meet these mandatory criteria. Variations in maximum supply current, seated height, and packaging format (Tape & Reel vs. Bulk) do not affect functional substitution capability within the specified electrical and mechanical constraints.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts are qualified replacements for the obsolete 7W20000034 based on electrical and mechanical parameter equivalence.

CPPC7L-A7BP-20.0TS (Cardinal Components Inc.): This part carries Active product status and ROHS3 compliance certification. It is supplied in Tape & Reel packaging format, suitable for automated assembly operations. The seated height of 0.075" (1.90mm) exceeds the original 7W20000034 specification of 0.056" (1.42mm); this difference must be evaluated against PCB layout constraints and clearance requirements. Maximum supply current is specified at 25mA.

SXO75C3A481-20.000M (Suntsu Electronics, Inc.): This part carries Active product status and ROHS3 compliance certification. It is supplied in Bulk packaging format. The seated height of 0.063" (1.60mm) is closer to the original specification than the Cardinal alternative. Maximum supply current is specified at 16mA, representing lower power consumption than the Cardinal option.

Both parts satisfy RoHS, REACH, and export control (ECCN EAR99) requirements equivalent to or exceeding the original component specifications.

Frequently Asked Questions (FAQ)

Q: Can CPPC7L-A7BP-20.0TS and SXO75C3A481-20.000M be used interchangeably with 7W20000034?

A: Both parts are electrical and mechanical equivalents within the specified parameter constraints. They share identical frequency (20 MHz), output type (CMOS), supply voltage (3.3V), function (Enable/Disable), frequency stability (±50ppm), operating temperature range (-40°C ~ 85°C), and package configuration (4-SMD, No Lead, 7.00mm x 5.00mm). Interchangeability is confirmed for applications where the seated height variation and maximum supply current differences do not create design conflicts.

Q: What is the significance of the seated height differences?

A: The 7W20000034 has a maximum seated height of 0.056" (1.42mm). The CPPC7L-A7BP-20.0TS measures 0.075" (1.90mm), and the SXO75C3A481-20.000M measures 0.063" (1.60mm). These differences must be evaluated against PCB layout, component clearance requirements, and enclosure constraints. The SXO75C3A481-20.000M presents a smaller height variance and may be preferred for space-constrained applications.

Q: What packaging formats are available?

A: The CPPC7L-A7BP-20.0TS is supplied in Tape & Reel (TR) format, optimized for high-volume automated assembly. The SXO75C3A481-20.000M is supplied in Bulk format. Selection depends on production volume, assembly equipment compatibility, and inventory management requirements.

Q: How do the supply current specifications compare?

A: The CPPC7L-A7BP-20.0TS specifies a maximum supply current of 25mA. The SXO75C3A481-20.000M specifies 16mA. The original 7W20000034 does not provide a maximum supply current specification. For power-sensitive applications, the SXO75C3A481-20.000M offers lower power consumption. Both values are typical for CMOS oscillators in this frequency range and should not create compatibility issues in standard applications.

Q: Are both substitute parts compliant with current regulatory standards?

A: Both CPPC7L-A7BP-20.0TS and SXO75C3A481-20.000M carry ROHS3 compliance certification and REACH Unaffected status, meeting current environmental and regulatory requirements. Both are classified under ECCN EAR99 and HTSUS 8542.39.0001, consistent with the original component classification.

Q: What is the product status significance?

A: The 7W20000034 is classified as Obsolete, indicating discontinued manufacturing and limited availability. Both substitute parts carry Active product status, ensuring ongoing availability, manufacturing support, and compliance with current industry standards. Active status provides supply chain stability for new designs and production continuity for legacy systems.
