DOC052F-012.8M OCXO Oscillator Equivalent & Substitute Parts

Part Overview

The DOC052F-012.8M is a 12.8 MHz OCXO (Oven Controlled Crystal Oscillator) with LVCMOS output, designed for applications requiring stable frequency generation at 3.3V supply voltage. This component operates across the industrial temperature range of -40°C to 85°C with frequency stability of ±50ppb. The part is currently obsolete, making identification of suitable substitute components essential for ongoing system support and new designs requiring equivalent functionality.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DOC052F-012.8M is determined by strict equivalence across the following critical parameters:

• Frequency: Must be 12.8 MHz
• Output Configuration: Must be LVCMOS
• Supply Voltage: Must be 3.3V
• Frequency Stability: Must be ±50ppb or better
• Operating Temperature Range: Must cover -40°C to 85°C
• Package Type: Must be 6-SMD, No Lead surface mount
• Compliance: Must maintain ROHS3 compliance and MSL 1 rating

The DOCAT052F-012.8M meets all substitution criteria as an active product from the same manufacturer (Connor Winfield) with identical electrical specifications and package footprint compatibility.

Parameter Comparison

Engineering Selection Recommendations

The DOCAT052F-012.8M is the direct substitute for the obsolete DOC052F-012.8M. Both components are manufactured by Connor Winfield and share identical electrical and functional specifications. The substitute part is currently in active production status, ensuring long-term availability and supply chain continuity.

The maximum seated height difference of 0.028" (0.71mm) between the two parts is within typical PCB design tolerances for surface mount applications and does not affect electrical performance or thermal management characteristics. Both parts maintain equivalent compliance certifications (ROHS3, REACH Unaffected, EAR99) and moisture sensitivity ratings.

Selection of the DOCAT052F-012.8M is appropriate for new designs and replacement applications where the DOC052F-012.8M is no longer available.

Frequently Asked Questions (FAQ)

Q: Can the DOCAT052F-012.8M be used as a direct replacement for the DOC052F-012.8M?

A: Yes. Both parts are electrically and mechanically equivalent with identical frequency, output type, supply voltage, stability, temperature range, and package footprint. The minor height difference (0.028") does not impact PCB layout or performance.

Q: What is the primary reason for substitution?

A: The DOC052F-012.8M is obsolete. The DOCAT052F-012.8M is the active equivalent from the same manufacturer with identical specifications.

Q: Are there any compliance or certification differences?

A: No. Both parts maintain ROHS3 compliance, REACH Unaffected status, MSL 1 rating, and EAR99 classification.

Q: Will the substitute part work in existing PCB designs?

A: Yes. The 6-SMD, No Lead package and footprint dimensions (0.555" L x 0.358" W) are identical. The maximum seated height of 0.335" for the substitute is within standard PCB design clearances.

Q: Are both parts available from the same manufacturer?

A: Yes. Both DOC052F-012.8M and DOCAT052F-012.8M are Connor Winfield products.
