OTETGLLTNF-125.000000 Equivalent & Substitute Parts

Part Overview

The OTETGLLTNF-125.000000 is a 125 MHz XO (Standard) LVPECL oscillator manufactured by Taitien, designed for applications requiring precision frequency generation with enable/disable functionality. This surface mount crystal oscillator operates at 3.3V supply voltage and is housed in a 6-SMD, No Lead package. The part is currently active in production with ROHS3 compliance and unlimited moisture sensitivity rating. Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are maintained across the critical performance parameters.

Key Parameters

Substitute Part Grouping Explanation

The P223-125.0M from Connor Winfield qualifies as a direct substitute based on the following critical parameters:

• Identical frequency specification: 125 MHz
• Matching output type: LVPECL
• Identical supply voltage: 3.3V
• Matching function: Enable/Disable capability
• Identical frequency stability: ±50ppm
• Matching operating temperature range: -40°C ~ 85°C
• Identical mounting type: Surface Mount
• Identical package type: 6-SMD, No Lead
• Matching footprint dimensions: 0.276" L x 0.197" W (7.00mm x 5.00mm)
• Equivalent compliance: ROHS3 Compliant, MSL 1 (Unlimited)

Substitution is valid when the receiving circuit design accommodates the specified electrical and thermal characteristics of the substitute part.

Parameter Comparison

Engineering Selection Recommendations

Both the OTETGLLTNF-125.000000 and P223-125.0M are active production parts with ROHS3 compliance and equivalent regulatory status (REACH Unaffected, ECCN EAR99). Selection between these parts should be based on:

• Supply chain availability and lead time requirements
• Current consumption budget: The P223-125.0M specifies a maximum supply current of 90mA compared to 75mA for the OTETGLLTNF-125.000000
• Physical height constraint: The P223-125.0M has a maximum seated height of 0.079" (2.00mm) versus 0.063" (1.60mm) for the OTETGLLTNF-125.000000
• Disable mode current: The P223-125.0M specifies 30µA disable current, whereas this parameter is not provided for the OTETGLLTNF-125.000000

Both parts maintain identical electrical performance specifications and are suitable for direct substitution in 125 MHz LVPECL oscillator applications with 3.3V supply.

Frequently Asked Questions (FAQ)

Q: Can the P223-125.0M replace the OTETGLLTNF-125.000000 in existing designs?

A: Yes, the P223-125.0M is electrically and mechanically compatible as a direct substitute. Both parts share identical frequency, output type, supply voltage, function, frequency stability, operating temperature range, and package footprint. Design review should confirm that the higher maximum supply current (90mA vs 75mA) and greater seated height (2.00mm vs 1.60mm) are acceptable for the application.

Q: What are the critical parameters for substitution between these oscillators?

A: The critical parameters are frequency (125 MHz), output type (LVPECL), supply voltage (3.3V), enable/disable function, frequency stability (±50ppm), operating temperature range (-40°C ~ 85°C), and package type (6-SMD, No Lead with 7.00mm x 5.00mm footprint). Deviation in any of these parameters invalidates substitution.

Q: Are there differences in power consumption between these parts?

A: Yes. The OTETGLLTNF-125.000000 specifies a maximum supply current of 75mA, while the P223-125.0M specifies 90mA maximum. The P223-125.0M also provides a disable mode current specification of 30µA. Power budget analysis should account for these differences.

Q: Do both parts meet the same compliance requirements?

A: Yes. Both parts are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99. Both carry MSL 1 (Unlimited) moisture sensitivity rating. Regulatory and environmental compliance is equivalent.

Q: What is the impact of the height difference between these parts?

A: The P223-125.0M has a maximum seated height of 0.079" (2.00mm) compared to 0.063" (1.60mm) for the OTETGLLTNF-125.000000. This 0.016" (0.40mm) difference should be evaluated against PCB clearance and enclosure constraints in the target application.
