Key Parameters

Substitute Part Grouping Explanation

Substitution of the DOC020F-012.8M is determined by strict equivalence across the following critical parameters:

• Frequency: 12.8 MHz (exact match required)
• Output Type: LVCMOS (signal compatibility requirement)
• Supply Voltage: 3.3V (power supply compatibility)
• Frequency Stability: ±20ppb (performance specification)
• Operating Temperature Range: 0°C ~ 70°C (thermal operating envelope)
• Package / Case: 6-SMD, No Lead (physical and electrical footprint compatibility)
• Mounting Type: Surface Mount (assembly process compatibility)
• RoHS Status: ROHS3 Compliant (regulatory compliance)
• Moisture Sensitivity Level: 1 (Unlimited) (handling and storage requirements)

The DOCAT020F-012.8M qualifies as a direct substitute based on full alignment with all critical parameters. The primary distinction is product status: the substitute is active production, whereas the original part is obsolete.

Parameter Comparison

Engineering Selection Recommendations

The DOCAT020F-012.8M is the manufacturer-recommended substitute for the obsolete DOC020F-012.8M. Both components maintain identical electrical specifications, frequency output, supply voltage, and thermal operating range. The substitute is currently in active production status, ensuring long-term availability and supply chain continuity.

The height differential of 0.028" (0.71mm) between the original and substitute components must be evaluated within the context of specific PCB assembly clearance requirements. This dimension variance falls within typical manufacturing tolerances for surface-mount oscillators and does not affect electrical performance or signal integrity.

Both components carry ROHS3 compliance and REACH unaffected status, satisfying current regulatory requirements for electronic component procurement and deployment.

Frequently Asked Questions (FAQ)

Q: Can the DOCAT020F-012.8M be used as a direct replacement for the DOC020F-012.8M?

A: Yes. The substitute maintains identical electrical specifications, frequency output, supply voltage, frequency stability, operating temperature range, package type, and mounting configuration. The components are pin-compatible and functionally equivalent.

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

A: The original part has a maximum seated height of 0.307" (7.80mm), while the substitute measures 0.335" (8.51mm). This 0.028" (0.71mm) difference must be verified against PCB assembly clearance specifications, including proximity to other components, shielding enclosures, or mechanical constraints. In most applications, this variance is accommodated within standard design tolerances.

Q: Why is the original DOC020F-012.8M classified as obsolete?

A: Obsolescence typically reflects manufacturer discontinuation of a product line. The DOCAT020F-012.8M represents the active production equivalent within the Connor Winfield oscillator portfolio, offering identical performance characteristics with ongoing manufacturing support.

Q: Are there any compliance or certification differences between the two parts?

A: No. Both components are ROHS3 compliant, REACH unaffected, and carry identical ECCN and HTSUS classifications. Regulatory and compliance status is equivalent.

Q: What parameters must remain constant for substitution to be valid?

A: Frequency (12.8 MHz), output type (LVCMOS), supply voltage (3.3V), frequency stability (±20ppb), operating temperature range (0°C ~ 70°C), package configuration (6-SMD, No Lead), and mounting type (Surface Mount) must all match exactly. Any deviation in these parameters requires re-evaluation of compatibility.
