Substitute Part Grouping Explanation

Substitution of the TXC CORPORATION 7B16000113 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

  • Frequency: 16 MHz
  • Frequency Tolerance: ±10ppm
  • Frequency Stability: ±9ppm
  • Load Capacitance: 9pF
  • Operating Mode: Fundamental
  • Operating Temperature Range: -20°C ~ 75°C
  • Mounting Type: Surface Mount
  • Package / Case: 4-SMD, No Lead

Acceptable Variation:

  • ESR (Equivalent Series Resistance): The main part specifies 40 Ohms; substitute parts specify 60 Ohms. This variation remains within acceptable operating parameters for the specified load capacitance and frequency.
  • Physical Dimensions: Substitute parts feature reduced dimensions (3.20mm x 2.50mm vs. 5.00mm x 3.20mm) and lower profile (0.60mm vs. 1.05mm), enabling direct PCB footprint compatibility while providing improved space efficiency.

The EPSON TSX-3225 series parts (16.0000MF09Z-AC0, 16.0000MF09Z-AC3, 16.0000MF09Z-AC6) satisfy all mandatory electrical parameters and maintain full functional equivalence with the obsolete TXC part.

Engineering Selection Recommendations

Primary Substitutes: The EPSON TSX-3225 series (16.0000MF09Z-AC0, 16.0000MF09Z-AC3, 16.0000MF09Z-AC6) are direct functional equivalents to the TXC 7B16000113. All three variants maintain identical electrical specifications and operating characteristics while offering active product status and enhanced compliance certifications (ROHS3).

Packaging Considerations:

  • TSX-3225 16.0000MF09Z-AC0: Available in Cut Tape (CT) & Digi-Reel® packaging (146,029 units in stock)
  • TSX-3225 16.0000MF09Z-AC3: Available in Cut Tape (CT) & Digi-Reel® packaging (91,720 units in stock)
  • TSX-3225 16.0000MF09Z-AC6: Available in Tape & Reel (TR) packaging (818 units in stock)

Selection between these three variants depends on procurement volume requirements and supply chain logistics. All three parts are electrically and mechanically interchangeable.

Compliance Status: All substitute parts exceed the compliance requirements of the obsolete TXC part, offering ROHS3 certification and REACH Unaffected status, ensuring regulatory compliance for current and future applications.

Frequently Asked Questions (FAQ)

Q: Can the EPSON TSX-3225 series parts directly replace the TXC 7B16000113 in existing designs?

A: Yes. The EPSON TSX-3225 16.0000MF09Z-AC0, AC3, and AC6 variants are direct functional replacements. All critical electrical parameters (frequency, tolerance, stability, load capacitance, and operating temperature) are identical. The 4-SMD, No Lead package format is equivalent, enabling direct PCB footprint compatibility.

Q: What is the difference between the three EPSON TSX-3225 variants?

A: The three variants (AC0, AC3, AC6) are electrically identical. The primary differences are packaging format and inventory availability. AC0 and AC3 are supplied in Cut Tape (CT) & Digi-Reel® format, while AC6 is supplied in Tape & Reel (TR) format. Selection depends on procurement volume and supply chain requirements.

Q: Does the higher ESR of the EPSON parts (60 Ohms vs. 40 Ohms) affect circuit performance?

A: The ESR difference does not compromise functional equivalence. Both specifications operate within acceptable parameters for the specified 9pF load capacitance and 16 MHz frequency. Circuit design margins accommodate this variation.

Q: Are the physical dimension differences between the TXC and EPSON parts significant?

A: The EPSON TSX-3225 parts feature smaller dimensions (3.20mm x 2.50mm vs. 5.00mm x 3.20mm) and lower profile (0.60mm vs. 1.05mm). These differences enable improved space efficiency while maintaining full PCB footprint compatibility. No design modifications are required.

Q: What compliance certifications do the substitute parts provide?

A: All EPSON TSX-3225 variants are ROHS3 Compliant and REACH Unaffected, exceeding the RoHS Compliance status of the obsolete TXC part. Both the main part and substitutes maintain MSL 1 (Unlimited) moisture sensitivity rating.

Q: Which EPSON variant should be selected for new production?

A: For new production applications, selection between AC0, AC3, and AC6 depends on procurement volume and supply chain logistics. All three variants are electrically and mechanically interchangeable. Higher inventory availability (AC0: 146,029 units; AC3: 91,720 units) supports sustained production requirements.
