Substitute Part Grouping Explanation

The AX7PAF3-125.0000C from Abracon LLC qualifies as a direct substitute for the ODEMDLLTNF-125.000000 based on the following critical parameters:

• Identical frequency specification: 125 MHz
• Matching output format: LVPECL
• Equivalent supply voltage: 3.3V
• Identical enable/disable function capability
• Matching frequency stability: ±25ppm
• Identical operating temperature range: -40°C ~ 85°C
• Identical package type and dimensions: 8-SMD, No Lead (7.00mm x 5.00mm)
• Equivalent surface mount mounting type
• Matching RoHS3 compliance and MSL 1 rating

Parameter Comparison

Engineering Selection Recommendations

The ODEMDLLTNF-125.000000 remains the primary selection for new designs due to its Active product status and current availability. The AX7PAF3-125.0000C serves as a qualified substitute when the primary part is unavailable, with the following considerations:

Both parts meet ROHS3 compliance and carry identical MSL 1 ratings, ensuring equivalent environmental and regulatory compliance. The AX7PAF3-125.0000C demonstrates lower maximum supply current specifications (94mA versus 110mA in normal operation, and 86mA versus 110mA in disable mode), which may provide marginal power consumption benefits in applications where this parameter is critical. However, the AX7PAF3-125.0000C is listed as Discontinued at DiGi Electronics, limiting its long-term availability for procurement.

Both oscillators are electrically and mechanically interchangeable within the specified parameter tolerances. The maximum seated height difference of 0.05mm (1.90mm versus 1.85mm) is negligible for standard PCB assembly processes.

Frequently Asked Questions (FAQ)

Q: Can the AX7PAF3-125.0000C be used as a direct replacement for the ODEMDLLTNF-125.000000?

A: Yes. Both parts share identical electrical specifications (125 MHz, LVPECL output, 3.3V supply, ±25ppm stability, -40°C to 85°C operating range) and mechanical compatibility (8-SMD, No Lead package, 7.00mm x 5.00mm footprint). The parts are pin-compatible and functionally equivalent.

Q: What are the differences between these two oscillators?

A: The primary differences are manufacturer (Taitien versus Abracon LLC) and supply current ratings. The AX7PAF3-125.0000C operates at lower maximum supply current (94mA versus 110mA). The AX7PAF3-125.0000C is discontinued at DiGi Electronics, while the ODEMDLLTNF-125.000000 remains in active production.

Q: Are there any height clearance concerns when substituting these parts?

A: The seated height difference is 0.05mm (1.85mm versus 1.90mm), which is within standard PCB assembly tolerances and does not present clearance issues for typical applications.

Q: Do both parts meet the same compliance standards?

A: Yes. Both oscillators are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity ratings, ensuring equivalent environmental and regulatory compliance.

Q: Which part should be selected for new designs?

A: The ODEMDLLTNF-125.000000 is recommended for new designs due to its Active product status and current inventory availability. The AX7PAF3-125.0000C should be reserved for applications where the primary part is unavailable.
