D75AS-020.0M-T Equivalent & Substitute Parts

Part Overview

The D75AS-020.0M-T is a 20 MHz Temperature Compensated Crystal Oscillator (TCXO) manufactured by Connor Winfield. This surface mount oscillator provides clipped sine wave output with 3.3V supply voltage and integrated enable/disable functionality. The device is designed for applications requiring stable frequency reference with temperature compensation across the 0°C to 70°C operating range. The part is currently active in production with full RoHS3 compliance and unlimited moisture sensitivity rating.

Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained within the specified parameter tolerances for this product category.

Substitute Part Grouping Explanation

Substitution eligibility for the D75AS-020.0M-T is determined by strict equivalence across the following critical parameters:

• Frequency: 20 MHz (exact match required)
• Type: TCXO (temperature compensation required)
• Output: Clipped Sine Wave (output waveform specification)
• Voltage - Supply: 3.3V (supply voltage compatibility)
• Frequency Stability: ±250ppb (frequency accuracy tolerance)
• Operating Temperature: 0°C ~ 70°C (thermal operating range)
• Current - Supply (Max): 6mA (power consumption limit)
• Package / Case: 10-SMD, No Lead (mechanical and electrical interface)
• Size / Dimension: 0.276" L x 0.197" W (7.00mm x 5.00mm) (PCB footprint compatibility)

The substitute part D75AS-020.0M meets all electrical parameter requirements. Mechanical compatibility is maintained within the specified package and dimensional constraints.

Parameter Comparison

Engineering Selection Recommendations

Both the D75AS-020.0M-T and D75AS-020.0M are active production parts from Connor Winfield with identical electrical specifications and RoHS3 compliance. The parts are functionally equivalent for 20 MHz TCXO applications requiring 3.3V supply and clipped sine wave output.

The D75AS-020.0M-T features a maximum seated height of 0.079" (2.00mm), while the D75AS-020.0M has a maximum seated height of 0.094" (2.40mm). Component selection should account for PCB clearance requirements and available vertical space in the application assembly.

Both parts maintain ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1), supporting equivalent handling and storage protocols.

Frequently Asked Questions (FAQ)

Q: Can D75AS-020.0M be used as a direct replacement for D75AS-020.0M-T?

A: Yes, the D75AS-020.0M is electrically equivalent to the D75AS-020.0M-T. Both parts deliver identical frequency, stability, output characteristics, and supply voltage specifications. The primary difference is the maximum seated height: 0.094" (2.40mm) versus 0.079" (2.00mm). Verify available PCB clearance before substitution.

Q: What are the critical parameters for TCXO substitution?

A: Frequency, output waveform, supply voltage, frequency stability, operating temperature range, and package type must match exactly. For the D75AS-020.0M-T, these parameters are: 20 MHz, clipped sine wave, 3.3V, ±250ppb, 0°C to 70°C, and 10-SMD No Lead package.

Q: Are there compliance differences between the substitute parts?

A: No. Both parts are ROHS3 compliant with MSL 1 (unlimited) moisture sensitivity rating. Handling, storage, and environmental compliance requirements are identical.

Q: Does the height difference affect electrical performance?

A: No. The height difference does not affect electrical performance. Height variation is a mechanical consideration relevant only to PCB assembly clearance and component placement constraints.
