Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DOC102V-012.8M is determined by strict alignment of the following critical parameters:

• Frequency: 12.8 MHz (exact match required)
• Output Type: LVCMOS (exact match required)
• Supply Voltage: 3.3V (exact match required)
• Package Type: 6-SMD, No Lead (exact match required)
• Mounting Type: Surface Mount (exact match required)
• Operating Temperature Range: -40°C to 85°C (exact match required)
• Frequency Stability: ±100ppb (exact match required)
• RoHS Compliance: ROHS3 Compliant (exact match required)

The DOCAT102V-012.8M qualifies as a direct substitute based on full alignment with all critical electrical and mechanical parameters. The addition of amplitude control functionality and the specified absolute pull range (±10ppm) represent enhancements that do not compromise compatibility with applications designed for the original DOC102V-012.8M.

Parameter Comparison

Engineering Selection Recommendations

The DOCAT102V-012.8M is the active production equivalent for the obsolete DOC102V-012.8M. Both components maintain identical electrical specifications for frequency, output type, supply voltage, and frequency stability. Both are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements.

The DOCAT102V-012.8M is currently in active production status with confirmed inventory availability (1096 pcs), whereas the DOC102V-012.8M is obsolete. For new designs and ongoing system support, the DOCAT102V-012.8M is the appropriate selection.

The maximum seated height difference of 0.71mm (8.51mm versus 7.80mm) must be evaluated within the context of specific PCB layout and enclosure constraints. The addition of amplitude control functionality in the DOCAT series provides enhanced performance characteristics without introducing incompatibility.

Frequently Asked Questions (FAQ)

Q: Can the DOCAT102V-012.8M directly replace the DOC102V-012.8M in existing designs?

A: Yes. Both components share identical frequency (12.8 MHz), output type (LVCMOS), supply voltage (3.3V), package configuration (6-SMD, No Lead), and operating temperature range (-40°C to 85°C). The DOCAT102V-012.8M is the active production equivalent.

Q: What is the significance of the amplitude control function in the DOCAT102V-012.8M?

A: Amplitude control is an additional feature that does not affect core oscillator compatibility. It provides enhanced performance flexibility without introducing electrical incompatibility with applications designed for the original DOC102V-012.8M.

Q: Does the 0.71mm height difference affect PCB compatibility?

A: The DOCAT102V-012.8M has a maximum seated height of 8.51mm compared to 7.80mm for the DOC102V-012.8M. This difference must be verified against specific PCB layout, component clearance requirements, and enclosure constraints for your application.

Q: Are both components compliant with current regulatory standards?

A: Yes. Both the DOC102V-012.8M and DOCAT102V-012.8M are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component manufacturing and use.

Q: What is the absolute pull range (APR) specification?

A: The DOCAT102V-012.8M specifies an APR of ±10ppm. The DOC102V-012.8M does not provide this specification in available documentation. APR defines the frequency adjustment range achievable through the control voltage input on VCOCXO devices.

Q: Is the DOCAT102V-012.8M currently available?

A: Yes. The DOCAT102V-012.8M is in active production status with 1096 pcs confirmed in new original inventory, whereas the DOC102V-012.8M is obsolete.
