DOC102F-024.576M OCXO Oscillator Equivalent & Substitute Parts

Part Overview

The DOC102F-024.576M is a 24.576 MHz OCXO (Oven Controlled Crystal Oscillator) with LVCMOS output, designed for applications requiring stable frequency generation at 3.3V supply voltage. This part is classified as obsolete, making identification of suitable substitute components essential for ongoing system support and new design implementations. The DOCAT102F-024.576M serves as the manufacturer-recommended active alternative, offering identical electrical specifications with improved availability.

Key Parameters

Substitute Part Grouping Explanation

Substitution between the DOC102F-024.576M and DOCAT102F-024.576M is determined by the following critical parameters:

• Frequency Match: Both parts operate at 24.576 MHz
• Output Compatibility: Both provide LVCMOS output
• Supply Voltage: Both require 3.3V supply
• Frequency Stability: Both maintain ±100ppb stability
• Temperature Range: Both operate across -40°C ~ 85°C
• Package Compatibility: Both use 6-SMD, No Lead surface mount package with identical footprint dimensions (14.10mm x 9.10mm)
• Regulatory Compliance: Both are ROHS3 compliant with MSL 1 rating

The primary distinction is product status: DOC102F-024.576M is obsolete, while DOCAT102F-024.576M is active production. Physical height differs slightly (7.80mm vs 8.51mm seated height), which must be verified against PCB clearance requirements.

Parameter Comparison

Engineering Selection Recommendations

The DOCAT102F-024.576M is the manufacturer-recommended substitute for the obsolete DOC102F-024.576M. Both parts meet identical electrical and mechanical specifications for frequency, output type, supply voltage, stability, and temperature range. Selection between these parts should be based on:

1. Availability: DOCAT102F-024.576M is in active production with higher inventory availability (1127 pcs vs 810 pcs)
2. PCB Clearance: Verify that the 0.71mm height difference (8.51mm vs 7.80mm seated height) does not conflict with component placement or enclosure constraints
3. Regulatory Compliance: Both parts satisfy ROHS3, REACH, and EAR99 requirements
4. Long-term Support: Active production status of DOCAT102F-024.576M ensures continued availability for future production runs and field replacements

Frequently Asked Questions (FAQ)

Q: Can DOCAT102F-024.576M directly replace DOC102F-024.576M in existing designs?

A: Yes, provided PCB clearance accommodates the 0.71mm height difference. All electrical parameters, package footprint dimensions, and mounting type are identical.

Q: What is the significance of the product status change from Obsolete to Active?

A: Active status indicates the DOCAT102F-024.576M is in current production with manufacturer support. Obsolete status for DOC102F-024.576M means limited or no future availability from the manufacturer.

Q: Are there any compliance differences between these parts?

A: No. Both parts carry identical ROHS3, REACH Unaffected, and EAR99 classifications.

Q: Does the seated height difference affect electrical performance?

A: No. The 0.71mm height difference is a physical dimension only and does not impact frequency, stability, output type, or supply voltage characteristics. Verification is required only for mechanical clearance in the application.

Q: What parameters must match for substitution eligibility?

A: Frequency (24.576 MHz), output type (LVCMOS), supply voltage (3.3V), frequency stability (±100ppb), operating temperature range (-40°C ~ 85°C), and package type (6-SMD, No Lead) must be identical.
