7V20070003 20 MHz Crystal Equivalent & Substitute Parts

Part Overview

The 7V20070003 is a 20 MHz fundamental mode crystal oscillator manufactured by TXC CORPORATION, designed for surface mount applications requiring precise frequency stability. This Active product is specified with 12pF load capacitance, 60 Ohms equivalent series resistance (ESR), and operates across the -20°C to 85°C temperature range. The component is housed in a compact 4-SMD, No Lead package measuring 3.20mm × 2.50mm with a maximum seated height of 0.90mm.

Substitute parts are identified when equivalent electrical performance can be maintained across critical parameters including frequency, frequency stability, load capacitance, and operating temperature range, while accommodating variations in package dimensions and ESR specifications within acceptable engineering tolerances.

Substitute Part Grouping Explanation

Substitution eligibility for the 7V20070003 is determined by strict equivalence across the following critical electrical parameters:

Primary Equivalence Criteria:

• Frequency: 20 MHz (exact match required)
• Frequency Stability: ±10ppm (exact match required)
• Load Capacitance: 12pF (exact match required)
• Operating Mode: Fundamental (exact match required)
• Operating Temperature Range: -20°C to 85°C (minimum coverage required)

Secondary Compatibility Parameters:

• Mounting Type: Surface Mount (required)
• Package Type: 4-SMD, No Lead (required for mechanical fit)
• RoHS Compliance: Required for regulatory alignment
• Moisture Sensitivity Level: MSL 1 or better (required)

Allowable Variations:

• ESR (Equivalent Series Resistance): Variation permitted within circuit design tolerance
• Package Dimensions: Variation permitted provided component fits within PCB footprint constraints
• Packaging Format: Variation permitted (Tape & Reel acceptable for equivalent bulk quantities)

The FW2000008 from Diodes Incorporated qualifies as a substitute based on matching all primary equivalence criteria and secondary compatibility parameters.

Engineering Selection Recommendations

7V20070003 (TXC CORPORATION):

• Active product status with 726 units in stock
• RoHS Compliant certification
• Larger package footprint (3.20mm × 2.50mm) suitable for applications with standard PCB layout constraints
• 60 Ohms ESR specification

FW2000008 (Diodes Incorporated - SaRonix-eCera™ FW Series):

• Active product status with 4104 units in stock
• ROHS3 Compliant certification (enhanced RoHS standard)
• Compact package footprint (2.00mm × 1.60mm) with reduced height (0.55mm) for space-constrained applications
• 80 Ohms ESR specification
• Supplied in Tape & Reel packaging format

Both parts maintain identical electrical performance across frequency, stability, load capacitance, and operating temperature specifications. Selection between these parts is determined by PCB layout requirements, available inventory, and packaging format preferences. The FW2000008 provides a smaller form factor option while maintaining full electrical equivalence.

Frequently Asked Questions (FAQ)

Q: Can the FW2000008 directly replace the 7V20070003 in existing designs?

A: Yes, provided the PCB footprint accommodates the smaller package dimensions (2.00mm × 1.60mm versus 3.20mm × 2.50mm). The electrical specifications are equivalent across all critical parameters including frequency, stability, load capacitance, and operating temperature range.

Q: What is the significance of the ESR difference (60 Ohms versus 80 Ohms)?

A: ESR variation between these parts is within acceptable engineering tolerance for most applications. Circuit design must account for ESR as a component of the oscillator load. Verify ESR compatibility with your specific oscillator circuit design parameters before implementation.

Q: Are both parts suitable for high-reliability applications?

A: Both parts carry Active product status and meet RoHS compliance requirements. The 7V20070003 is RoHS Compliant, while the FW2000008 is ROHS3 Compliant. Both maintain MSL 1 (Unlimited) moisture sensitivity rating and REACH Unaffected status, suitable for industrial and commercial applications.

Q: What packaging format differences exist between these parts?

A: The 7V20070003 is specified with standard packaging (format not explicitly detailed). The FW2000008 is supplied in Tape & Reel (TR) format, which is standard for high-volume surface mount assembly operations.

Q: Can I use the FW2000008 in applications originally designed for the 7V20070003?

A: Electrical substitution is valid. Mechanical substitution requires verification that the smaller package dimensions (2.00mm × 1.60mm) fit within the PCB footprint and that the reduced height (0.55mm) does not create clearance conflicts with adjacent components or assembly fixtures.

Q: Are there any temperature or frequency stability concerns when substituting between these parts?

A: No. Both parts operate across the identical temperature range (-20°C to 85°C) and maintain the same frequency stability specification (±10ppm). Frequency tolerance is also equivalent at ±10ppm for both parts.
