DOC020F-025.0M OCXO Oscillator Equivalent & Substitute Parts

Part Overview

The DOC020F-025.0M is a 25 MHz OCXO (Oven Controlled Crystal Oscillator) manufactured by Connor Winfield, designed for applications requiring stable frequency output with LVCMOS logic levels at 3.3V supply voltage. This component operates across the 0°C to 70°C temperature range with ±20ppb frequency stability. The part is classified as obsolete, making identification of suitable substitute components essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the DOC020F-025.0M is determined by strict equivalence across the following critical parameters:

• Frequency: 25 MHz (exact match required)
• Output Type: LVCMOS (logic family compatibility)
• Supply Voltage: 3.3V (electrical interface requirement)
• Frequency Stability: ±20ppb (performance specification)
• Operating Temperature Range: 0°C to 70°C (thermal envelope)
• Mounting Type: Surface Mount (assembly compatibility)
• Package Configuration: 6-SMD, No Lead (footprint compatibility)
• Physical Dimensions: 0.555" L × 0.358" W (14.10mm × 9.10mm) (board layout constraint)
• Compliance Standards: ROHS3 Compliant, REACH Unaffected (regulatory requirement)

The DOXSC020F-025.0M qualifies as a direct substitute based on matching all critical electrical and mechanical parameters. The primary distinction is product status: DOXSC020F-025.0M is active production, whereas DOC020F-025.0M is obsolete.

Parameter Comparison

Engineering Selection Recommendations

The DOXSC020F-025.0M is the direct substitute for the obsolete DOC020F-025.0M. Both components maintain identical electrical specifications, frequency output, and thermal operating range. The DOXSC020F-025.0M is currently in active production status, ensuring long-term availability and supply chain continuity.

Both parts satisfy ROHS3 compliance and REACH regulatory requirements. The DOXSC020F-025.0M is available in Tape & Reel packaging, which is standard for production environments. The seated height difference of 0.028" (0.71mm) between the two parts is within typical PCB assembly tolerances and does not present a constraint for standard surface mount applications.

Frequently Asked Questions (FAQ)

Q: Can DOXSC020F-025.0M be used as a direct replacement for DOC020F-025.0M in existing designs?

A: Yes. Both parts share identical frequency, output logic, supply voltage, frequency stability, operating temperature range, and physical footprint dimensions. The DOXSC020F-025.0M is electrically and mechanically compatible with designs originally specified for DOC020F-025.0M.

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

A: The DOC020F-025.0M has a maximum seated height of 0.307" (7.80mm), while the DOXSC020F-025.0M measures 0.335" (8.51mm). This 0.028" (0.71mm) difference is within standard PCB assembly clearance specifications and does not affect compatibility in typical applications.

Q: Why is DOC020F-025.0M classified as obsolete?

A: The DOC020F-025.0M has been discontinued by Connor Winfield. The DOXSC020F-025.0M represents the active production equivalent within the same product family.

Q: Are there packaging differences between these parts?

A: The DOC020F-025.0M is supplied in bulk packaging, while the DOXSC020F-025.0M is available in Tape & Reel (TR) format. Tape & Reel packaging is standard for automated assembly processes and provides improved handling and traceability.

Q: Do both parts meet the same regulatory compliance standards?

A: Yes. Both DOC020F-025.0M and DOXSC020F-025.0M are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: What is the Absolute Pull Range (APR) specification for these oscillators?

A: The DOC020F-025.0M does not specify an APR value. The DOXSC020F-025.0M specifies ±15ppm APR. This parameter does not affect substitution compatibility, as both parts maintain the required ±20ppb frequency stability across the operating temperature range.
