TVECCLSANF-25.000000 Equivalent & Substitute Parts

Part Overview

The TVECCLSANF-25.000000 is a 25 MHz Temperature Compensated Crystal Oscillator (TCXO) manufactured by Taitien, designed for applications requiring stable frequency output with clipped sine wave characteristics. This oscillator operates across a 2.8V to 3.3V supply range with ±2ppm frequency stability and is housed in a 4-SMD, No Lead surface mount package.

The product is classified as Obsolete, making identification of functionally equivalent substitute components essential for ongoing system support, design updates, and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TVECCLSANF-25.000000 is determined by the following critical parameters:

• Frequency Match: 25 MHz (exact match required)
• Oscillator Type: TCXO (Temperature Compensated Crystal Oscillator)
• Output Signal: Clipped Sine Wave
• Package Type: 4-SMD, No Lead surface mount configuration
• Operating Temperature Range: -40°C to 85°C minimum
• Supply Voltage Compatibility: Overlap within 2.8V ~ 3.3V range

The AST3TQ53-T-25.000MHZ-2-SW from Abracon LLC meets these core substitution criteria. While dimensional and electrical specifications show minor variations, the part maintains functional equivalence for the specified frequency, oscillator class, output type, and thermal operating envelope.

Parameter Comparison

Engineering Selection Recommendations

The AST3TQ53-T-25.000MHZ-2-SW qualifies as a functional substitute for the obsolete TVECCLSANF-25.000000 based on matching core oscillator specifications: 25 MHz frequency, TCXO type, clipped sine wave output, and 4-SMD No Lead package configuration.

Both parts maintain ROHS3 compliance and operate across the -40°C to 85°C temperature range. The Abracon part is currently in Active product status, ensuring ongoing availability and supply chain continuity.

Design considerations for substitution include:

• Supply voltage operation at 3.3V nominal (versus the Taitien part's 2.8V ~ 3.3V range)
• Frequency stability improvement: ±280ppb versus ±2ppm
• Increased maximum supply current: 6mA versus 2mA
• Dimensional increase: 5.20mm x 3.40mm versus 5.00mm x 3.20mm
• Height increase: 1.60mm versus 1.20mm
• MSL rating change from 1 to 3, requiring adjusted moisture handling procedures

Frequently Asked Questions (FAQ)

Q: Can the AST3TQ53-T-25.000MHZ-2-SW directly replace the TVECCLSANF-25.000000 in existing designs?

A: Direct substitution is possible if the design accommodates the dimensional differences (5.20mm x 3.40mm footprint, 1.60mm height), operates at 3.3V supply voltage, and can tolerate the increased current draw of 6mA. PCB layout verification is required to confirm clearance for the larger package dimensions.

Q: What is the impact of the frequency stability difference (±280ppb vs ±2ppm)?

A: The Abracon part provides superior frequency stability at ±280ppb compared to the Taitien part's ±2ppm specification. This represents an improvement and poses no compatibility risk for applications requiring the original stability level.

Q: Are there moisture handling differences between these parts?

A: Yes. The TVECCLSANF-25.000000 carries MSL 1 (Unlimited), while the AST3TQ53-T-25.000MHZ-2-SW carries MSL 3 (168 Hours). MSL 3 components require storage in dry conditions and have a 168-hour floor life after moisture exposure. Implement appropriate moisture control procedures per IPC-A-610 standards.

Q: Do both parts meet RoHS requirements?

A: Yes, both components are ROHS3 Compliant, ensuring compatibility with RoHS-regulated applications and supply chains.

Q: What is the significance of the product status difference?

A: The TVECCLSANF-25.000000 is Obsolete, indicating discontinued manufacturing and limited availability. The AST3TQ53-T-25.000MHZ-2-SW is Active, ensuring reliable long-term procurement and supply chain support for new designs and ongoing production.
