Engineering Selection Recommendations

AX7PBF1-2100.0000C (MFR Recommended Substitute): This part is designated as the manufacturer-recommended substitute. It maintains all critical electrical and mechanical parameters with the exception of supply voltage, which operates at 2.5V instead of 3.3V. Selection of this part requires circuit design compatibility with 2.5V supply rails. This part carries ROHS3 compliance and MSL 1 rating identical to the main part.

AX7PAF1-2100.0000C (Parametric Equivalent): This part is a parametric equivalent offering identical electrical and mechanical specifications to the main part, including 3.3V supply voltage. It provides direct functional replacement without circuit modification requirements. This part also maintains ROHS3 compliance and MSL 1 rating.

Both substitute parts are discontinued at DiGi Electronics, consistent with the main part status. Selection between substitutes depends on circuit supply voltage requirements and design constraints.

Frequently Asked Questions (FAQ)

Q: Can AX7PBF1-2100.0000C be used as a direct replacement for AX7PAF3-2100.0000C? A: AX7PBF1-2100.0000C is electrically and mechanically compatible with the main part. The primary difference is supply voltage: 2.5V versus 3.3V. Direct substitution is possible only if your circuit design operates on 2.5V supply rails. Verify power supply compatibility before implementation.

Q: What is the difference between the MFR Recommended and Parametric Equivalent substitutes? A: AX7PBF1-2100.0000C (MFR Recommended) operates at 2.5V supply voltage. AX7PAF1-2100.0000C (Parametric Equivalent) operates at 3.3V supply voltage, matching the original part. Both maintain identical frequency, output type, package, and thermal specifications. Choose based on your circuit's supply voltage requirements.

Q: Are all three parts pin-compatible? A: Yes. All three parts use the 8-SMD, No Lead package with identical physical dimensions (0.276" L x 0.197" W, 7.00mm x 5.00mm) and maximum seated height (0.075" / 1.90mm). PCB layout compatibility is assured across all variants.

Q: Do these parts meet RoHS and environmental compliance requirements? A: All three parts are ROHS3 compliant and REACH unaffected. Moisture sensitivity level is MSL 1 (Unlimited) for all variants, indicating no moisture sensitivity restrictions during storage or handling.

Q: What is the frequency stability specification for these oscillators? A: All three parts maintain ±25ppm frequency stability across the operating temperature range of -40°C to 85°C.
