Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DOC102F-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 ±100ppb
• Operating Temperature Range: Must span -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 DOCAT102F-012.8M meets all substitution criteria and is classified as the manufacturer-recommended equivalent. Both parts share identical electrical specifications and package footprint compatibility, with the primary distinction being product status and minor dimensional variation in seated height.

Parameter Comparison

Engineering Selection Recommendations

The DOCAT102F-012.8M is the appropriate substitute for the obsolete DOC102F-012.8M. Both components are manufactured by Connor Winfield and maintain identical electrical performance specifications. The substitute part is currently in active production status with confirmed inventory availability (967 pcs), ensuring supply chain continuity.

Both parts satisfy ROHS3 compliance requirements and carry REACH Unaffected status, meeting regulatory requirements for industrial and commercial applications. The 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 functionality or signal integrity.

Selection of the DOCAT102F-012.8M is supported by manufacturer recommendation and equivalent performance across all specified electrical and mechanical parameters.

Frequently Asked Questions (FAQ)

Q: Can the DOCAT102F-012.8M be used as a direct replacement for the DOC102F-012.8M?

A: Yes. Both parts are electrically identical with matching frequency, output type, supply voltage, stability, and temperature range specifications. The package footprint is identical, and the minor seated height variation does not impact PCB layout or assembly compatibility.

Q: What is the significance of the product status difference?

A: The DOC102F-012.8M is obsolete and no longer manufactured. The DOCAT102F-012.8M is in active production, ensuring long-term availability and supply chain reliability for new designs and system maintenance.

Q: Are there any compliance differences between these parts?

A: No. Both parts maintain ROHS3 compliance, REACH Unaffected status, and identical moisture sensitivity levels. Regulatory and environmental requirements are equivalent.

Q: Does the seated height difference affect circuit performance?

A: No. The 0.028" (0.71mm) height difference is a mechanical dimension only and does not affect electrical characteristics, signal integrity, or frequency stability. Standard PCB design practices accommodate this variation.

Q: What parameters must match for substitution eligibility?

A: Frequency (12.8 MHz), output type (LVCMOS), supply voltage (3.3V), frequency stability (±100ppb), operating temperature range (-40°C to 85°C), and package type (6-SMD, No Lead) must all be identical. All specified parameters match between these two parts.
