DOC100F-012.8M OCXO Oscillator Equivalent & Substitute Parts

Part Overview

The DOC100F-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 part operates across the 0°C to 70°C temperature range with ±100ppb frequency stability and is packaged in a 6-SMD, No Lead surface mount configuration.

The DOC100F-012.8M is currently listed as obsolete. Identifying equivalent substitute parts is necessary to maintain design continuity and ensure supply chain availability for new production runs or system upgrades.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DOC100F-012.8M is determined by strict alignment across the following critical parameters:

• Frequency: Exact match at 12.8 MHz
• Output Type: LVCMOS compatibility required
• Supply Voltage: 3.3V operation mandatory
• Frequency Stability: ±100ppb specification
• Package / Case: 6-SMD, No Lead form factor
• Mounting Type: Surface Mount
• Operating Temperature Range: 0°C ~ 70°C minimum coverage
• Compliance: ROHS3 Compliant, REACH Unaffected

The DOCAT100F-012.8M meets all substitution criteria. Both parts are manufactured by Connor Winfield and share identical electrical specifications and package footprint compatibility.

Parameter Comparison

Engineering Selection Recommendations

The DOCAT100F-012.8M is the direct substitute for the obsolete DOC100F-012.8M. Both parts are manufactured by Connor Winfield and maintain identical electrical performance specifications, frequency accuracy, and output characteristics.

The DOCAT100F-012.8M carries Active product status, ensuring ongoing availability and supply chain support. Both parts satisfy ROHS3 compliance and REACH regulatory requirements, making them suitable for applications with environmental and regulatory constraints.

The maximum seated height difference of 0.028" (0.71mm) between the two parts is within typical PCB design tolerances for surface mount oscillators and does not impact circuit board layout compatibility.

Frequently Asked Questions (FAQ)

Q: Can the DOCAT100F-012.8M be used as a direct replacement for the DOC100F-012.8M?

A: Yes. Both parts share identical frequency, output type, supply voltage, frequency stability, package footprint, and operating temperature specifications. The DOCAT100F-012.8M is the active production equivalent.

Q: Are there any physical compatibility concerns between these parts?

A: The DOCAT100F-012.8M has a maximum seated height of 0.335" (8.51mm) compared to 0.307" (7.80mm) for the DOC100F-012.8M. This 0.028" (0.71mm) difference is within standard PCB design clearances for surface mount components and does not affect footprint compatibility.

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

A: Yes. Both the DOC100F-012.8M and DOCAT100F-012.8M are ROHS3 Compliant and REACH Unaffected, with identical Moisture Sensitivity Level ratings of 1 (Unlimited).

Q: What is the primary reason for substitution?

A: The DOC100F-012.8M is obsolete. The DOCAT100F-012.8M is the active production part from the same manufacturer with identical electrical and mechanical specifications.

Q: Are the frequency stability and output characteristics identical?

A: Yes. Both parts operate at 12.8 MHz with ±100ppb frequency stability and LVCMOS output at 3.3V supply voltage.
