Parameter Comparison

Engineering Selection Recommendations

AX7DCF1-2100.0000C (MFR Recommended Substitute): This part is designated as the manufacturer-recommended substitute. It maintains identical electrical performance and mechanical compatibility with the main part across all critical parameters. The primary difference is the reduced supply voltage of 1.8V versus 2.5V. This substitute is appropriate for designs where 1.8V supply rails are available or preferred. Current inventory of 839 pcs is available.

AX7DBF1-2100.0000C (Parametric Equivalent): This part provides parametric equivalence with identical supply voltage (2.5V) and all other electrical specifications matching the main part. It serves as a direct functional replacement for applications requiring 2.5V operation. Current inventory of 786 pcs is available.

All substitute parts maintain ROHS3 compliance and MSL 1 (Unlimited) rating, ensuring compatibility with standard manufacturing and storage requirements.

Frequently Asked Questions (FAQ)

Q: Can AX7DCF1-2100.0000C be used as a direct replacement for AX7DBF4-2100.0000C? A: AX7DCF1-2100.0000C is the manufacturer-recommended substitute and maintains all electrical and mechanical specifications. The supply voltage differs at 1.8V versus 2.5V. Substitution is valid only if your circuit design supports 1.8V operation.

Q: What is the difference between the MFR Recommended and Parametric Equivalent substitutes? A: AX7DCF1-2100.0000C (MFR Recommended) operates at 1.8V supply voltage. AX7DBF1-2100.0000C (Parametric Equivalent) operates at 2.5V supply voltage, matching the original part. Both maintain identical frequency, output type, package, and thermal specifications.

Q: Are all three parts pin-compatible? A: All three parts use the 8-SMD, No Lead package with identical physical dimensions (7.00mm x 5.00mm) and height (1.90mm). Pin compatibility depends on circuit design and supply voltage requirements.

Q: Do the substitute parts have the same frequency stability? A: Yes. All three parts maintain ±25ppm frequency stability across the -40°C ~ 85°C operating temperature range.

Q: What is the current consumption difference between the main part and substitutes? A: All three parts have identical maximum supply current specifications: 70mA during operation and 65mA in disable mode.

Q: Are there any compliance or certification differences? A: All three parts are ROHS3 compliant with MSL 1 (Unlimited) rating. No compliance differences exist between the main part and substitutes.
