Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the D75A-020.0M-T is determined by strict equivalence across the following critical parameters:

• Frequency: 20 MHz (exact match required)
• Output Configuration: LVCMOS (exact match required)
• Supply Voltage: 3.3V (exact match required)
• Frequency Stability: ±280ppb (exact match required)
• Operating Temperature Range: 0°C ~ 70°C (exact match required)
• Package Type: 10-SMD, No Lead (exact match required)
• Enable/Disable Function: Present (exact match required)
• RoHS and Compliance Status: ROHS3 Compliant (exact match required)

The D75A-020.0M qualifies as a direct substitute based on identical electrical specifications and functional characteristics across all critical parameters. Mechanical height variation (2.40mm vs. 2.00mm) remains within acceptable PCB assembly tolerances for surface mount components in this package class.

Parameter Comparison

Engineering Selection Recommendations

Both D75A-020.0M-T and D75A-020.0M are Active products with identical electrical specifications and full ROHS3 compliance. Selection between these parts is based on availability and inventory status. The D75A-020.0M offers higher inventory availability (1327 pcs vs. 658 pcs) while maintaining complete electrical and functional equivalence. The 0.40mm height difference (2.40mm vs. 2.00mm) is within standard PCB assembly clearance specifications for 10-SMD packages and does not impact circuit performance or board layout compatibility.

Frequently Asked Questions (FAQ)

Q: Can D75A-020.0M be used as a direct replacement for D75A-020.0M-T?

A: Yes. Both parts are electrically identical with matching frequency (20 MHz), output type (LVCMOS), supply voltage (3.3V), frequency stability (±280ppb), operating temperature range (0°C ~ 70°C), and package configuration (10-SMD, No Lead). The height difference of 0.40mm is within acceptable tolerances for surface mount assembly.

Q: What are the critical parameters that must match for substitution?

A: Frequency, output type, supply voltage, frequency stability, operating temperature range, enable/disable function, package type, and compliance certifications must all match exactly. Any deviation in these parameters disqualifies a part as a substitute.

Q: Does the height difference affect PCB design?

A: No. The 0.40mm height variation (2.00mm vs. 2.40mm) remains within standard clearance specifications for 10-SMD surface mount components and does not require PCB layout modifications.

Q: Are both parts RoHS compliant?

A: Yes. Both D75A-020.0M-T and D75A-020.0M are ROHS3 Compliant with Moisture Sensitivity Level 1 (Unlimited).

Q: What is the difference between these two part numbers?

A: The parts are functionally and electrically equivalent. The primary difference is the seated height specification (2.00mm vs. 2.40mm) and inventory availability. Both maintain identical electrical performance and compliance status.
