Substitute Part Grouping Explanation

Substitution of the DOC102F-049.152M is determined by strict equivalence across the following critical parameters:

• Frequency: 49.152 MHz (exact match required)
• Output Configuration: LVCMOS (no alternative output types acceptable)
• Supply Voltage: 3.3V (no voltage variation permitted)
• Frequency Stability: ±100ppb (stability specification must be met or exceeded)
• Operating Temperature Range: -40°C ~ 85°C (full range coverage required)
• Package and Mounting: 6-SMD, No Lead surface mount (physical and electrical compatibility)
• Compliance Standards: ROHS3 Compliant, REACH Unaffected (regulatory alignment)

The DOCAT102F-049.152M qualifies as a direct substitute based on identical electrical specifications and package compatibility. The primary distinction is product status: the DOC102F-049.152M is obsolete, while the DOCAT102F-049.152M is active production.

Engineering Selection Recommendations

The DOCAT102F-049.152M is the recommended substitute for the obsolete DOC102F-049.152M. Selection is based on the following engineering criteria:

Product Status Alignment: The DOCAT102F-049.152M is in active production status, ensuring long-term availability and supply chain continuity. The DOC102F-049.152M obsolete status creates risk for future procurement and support.

Electrical Equivalence: All critical electrical parameters are identical, including frequency, output type, supply voltage, and frequency stability. No circuit redesign or signal conditioning modifications are required.

Regulatory Compliance: Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying current environmental and regulatory requirements.

Physical Compatibility: Identical footprint and mounting type ensure direct PCB layout compatibility. The maximum seated height difference of 0.028" (0.71mm) is within standard PCB assembly tolerances and does not impact board-level integration.

Manufacturer Continuity: Both parts are manufactured by Connor Winfield, ensuring consistent quality standards and technical support.

Frequently Asked Questions (FAQ)

Q: Can the DOCAT102F-049.152M be used as a direct replacement for the DOC102F-049.152M without circuit modifications?

A: Yes. The DOCAT102F-049.152M is electrically and mechanically equivalent. No circuit redesign is required. The parts are pin-compatible and functionally identical across all specified parameters.

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

A: The DOC102F-049.152M has a maximum seated height of 0.307" (7.80mm), while the DOCAT102F-049.152M is 0.335" (8.51mm). This 0.028" (0.71mm) difference is within standard PCB assembly tolerances and does not affect board-level clearance or component placement for typical applications.

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

A: No. Both parts are ROHS3 compliant and REACH unaffected. Regulatory and environmental certifications are identical.

Q: Why is the DOC102F-049.152M classified as obsolete?

A: Product obsolescence is determined by the manufacturer based on production lifecycle decisions. The DOCAT102F-049.152M represents the active production equivalent within the Connor Winfield product line.

Q: What inventory considerations should be evaluated when transitioning from DOC102F-049.152M to DOCAT102F-049.152M?

A: The DOC102F-049.152M has 920 pieces in stock, while the DOCAT102F-049.152M has 793 pieces available. For new designs and ongoing production, the DOCAT102F-049.152M should be specified to ensure supply continuity and avoid future obsolescence issues.

Q: Are there any thermal or frequency stability differences between these oscillators?

A: No. Both parts operate across the identical temperature range (-40°C ~ 85°C) and maintain the same frequency stability specification of ±100ppb. Thermal performance and frequency accuracy are equivalent.
