TYKTALSANF-26.000000 Equivalent & Substitute Parts

Part Overview

The TYKTALSANF-26.000000 is a 26 MHz Temperature Compensated Crystal Oscillator (TCXO) manufactured by Taitien, designed for applications requiring stable frequency output with clipped sine wave characteristics. This component operates at 1.8V supply voltage and is housed in a compact 4-SMD, No Lead surface mount package. The part is currently in active production status with robust inventory availability (1258 pcs in stock). Substitute parts are identified when equivalent electrical performance and mechanical compatibility are required due to supply constraints, design flexibility, or procurement optimization.

Substitute Part Grouping Explanation

The RTX-2520AD31-S-26.000-TR from Raltron Electronics qualifies as a parametric equivalent based on the following critical substitution criteria:

Electrical Compatibility:

• Identical frequency: 26 MHz
• Identical oscillator type: TCXO
• Identical output format: Clipped Sine Wave
• Identical supply voltage: 1.8V
• Identical frequency stability: ±500ppb
• Identical operating temperature range: -40°C ~ 85°C

Mechanical Compatibility:

• Identical package type: 4-SMD, No Lead
• Identical physical dimensions: 0.098" L x 0.079" W (2.50mm x 2.00mm)
• Identical maximum seated height: 0.031" (0.80mm)
• Identical mounting type: Surface Mount

Regulatory & Compliance Alignment:

• Identical RoHS status: ROHS3 Compliant
• Identical MSL rating: 1 (Unlimited)
• Identical REACH status: REACH Unaffected
• Identical ECCN classification: EAR99

The substitute part exhibits a marginal increase in maximum supply current (2.5mA vs. 2mA), which does not disqualify substitution as the difference remains within typical design margin tolerances for 1.8V TCXO applications.

Parameter Comparison

Engineering Selection Recommendations

Both the TYKTALSANF-26.000000 and RTX-2520AD31-S-26.000-TR are active production components with full regulatory compliance (ROHS3 and REACH). Selection between these parts should be based on:

Primary Factors:

• Supply availability and lead time requirements
• Procurement cost and volume pricing
• Existing supplier relationships and qualification status

Secondary Considerations:

• The RTX-2520AD31-S-26.000-TR exhibits higher maximum supply current (2.5mA vs. 2mA), which may impact power budget calculations in battery-powered or ultra-low-power applications
• Both components maintain identical frequency stability (±500ppb) and operating temperature performance across the full -40°C to 85°C range
• Identical MSL rating (1) eliminates moisture sensitivity as a differentiation factor

Frequently Asked Questions (FAQ)

Q: Can RTX-2520AD31-S-26.000-TR be used as a direct replacement for TYKTALSANF-26.000000?

A: Yes. Both components share identical electrical specifications (26 MHz, TCXO, clipped sine wave output, 1.8V supply, ±500ppb stability, -40°C to 85°C operating range) and mechanical form factor (4-SMD, No Lead, 2.50mm x 2.00mm x 0.80mm max height). No circuit modifications are required for substitution.

Q: What is the significance of the current supply difference (2mA vs. 2.5mA)?

A: The RTX-2520AD31-S-26.000-TR specifies a maximum supply current of 2.5mA compared to 2mA for the TYKTALSANF-26.000000. This 0.5mA difference is marginal and typically accommodated within standard power supply design margins. Applications with strict power budgets should account for this variance during design validation.

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

A: Both components are ROHS3 compliant and REACH unaffected, meeting standard environmental and regulatory requirements. Both maintain MSL rating 1 (unlimited moisture sensitivity), indicating robust handling characteristics. Specific high-reliability qualifications (military, aerospace, automotive) must be verified against individual application requirements and manufacturer datasheets.

Q: Do the parts require different PCB footprints?

A: No. Both components use identical 4-SMD, No Lead packaging with matching physical dimensions (0.098" L x 0.079" W, 2.50mm x 2.00mm) and maximum seated height (0.031", 0.80mm). PCB footprints and assembly processes remain unchanged.

Q: What is the frequency stability specification and how does it affect application suitability?

A: Both parts specify ±500ppb frequency stability across the -40°C to 85°C operating range. This specification defines the maximum frequency deviation from the nominal 26 MHz center frequency. Applications requiring tighter stability must confirm this specification meets system-level timing requirements.
