AX7PAF4-100.0000C Equivalent & Substitute Parts

Part Overview

The AX7PAF4-100.0000C is a 100 MHz XO (Standard) LVPECL Oscillator manufactured by Abracon LLC, part of the ClearClock™ AX7 series. This surface mount oscillator operates at 3.3V with Enable/Disable functionality and is housed in an 8-SMD, No Lead package. The part is currently discontinued at DiGi Electronics, making equivalent substitutes necessary for ongoing production and maintenance applications. Substitute parts must maintain identical electrical performance and mechanical compatibility to ensure seamless integration into existing designs.

Substitute Part Grouping Explanation

Substitute parts for the AX7PAF4-100.0000C are qualified based on the following critical parameters:

• Frequency: 100 MHz (exact match required)
• Output Type: LVPECL (exact match required)
• Supply Voltage: 3.3V (exact match required)
• Function: Enable/Disable (exact match required)
• Frequency Stability: ±25ppm (exact match required)
• Operating Temperature Range: -40°C ~ 85°C (exact match required)
• Package / Case: 8-SMD, No Lead (exact match required)
• Mounting Type: Surface Mount (exact match required)
• Physical Dimensions: 7.00mm x 5.00mm footprint (exact match required)
• Compliance: ROHS3 Compliant, MSL 1 (exact match required)

Two substitute parts meet these criteria: the AX7PAF1-100.0000 from Abracon LLC and the ODEMDLLTNF-100.000000 from Taitien. Both maintain identical electrical specifications and mechanical compatibility with the original part.

Parameter Comparison

Engineering Selection Recommendations

AX7PAF1-100.0000 (Abracon LLC): This part is the primary substitute, offering identical electrical and mechanical specifications to the main part. As an active product from the same manufacturer and series, it provides the highest compatibility assurance. The part is available in Strip packaging and maintains all compliance certifications including ROHS3 and MSL 1.

ODEMDLLTNF-100.000000 (Taitien): This part qualifies as a direct substitute with all critical electrical parameters matching the original. The maximum supply current is higher (110mA vs. 94mA), and the seated height is slightly lower (1.85mm vs. 1.90mm), both within acceptable mechanical tolerances for the 8-SMD, No Lead package. The part maintains ROHS3 compliance and MSL 1 rating. This option provides an alternative source from a different manufacturer.

Both substitutes are suitable for direct replacement in applications requiring a 100 MHz LVPECL oscillator with 3.3V supply and Enable/Disable functionality.

Frequently Asked Questions (FAQ)

Q: Can the AX7PAF1-100.0000 be used as a direct replacement for the AX7PAF4-100.0000C?

A: Yes. Both parts share identical electrical specifications (100 MHz, LVPECL output, 3.3V supply, ±25ppm stability, -40°C ~ 85°C operating range) and mechanical compatibility (8-SMD, No Lead package, 7.00mm x 5.00mm footprint). The primary difference is product status: AX7PAF1-100.0000 is active while AX7PAF4-100.0000C is discontinued.

Q: What are the differences between the Abracon and Taitien substitutes?

A: Both parts meet all critical electrical and mechanical requirements. The Taitien ODEMDLLTNF-100.000000 has a maximum supply current of 110mA compared to 94mA for the Abracon parts, and a seated height of 1.85mm versus 1.90mm. These differences do not affect functional compatibility in standard applications.

Q: Are there any compliance or certification differences between these parts?

A: All three parts are ROHS3 compliant with MSL 1 (Unlimited) rating. Both substitutes maintain the same compliance profile as the original part.

Q: Which substitute should be selected for new designs?

A: The AX7PAF1-100.0000 is recommended for new designs as it is from the same manufacturer and series as the original part, ensuring maximum design continuity. The Taitien ODEMDLLTNF-100.000000 is suitable as an alternative source option.

Q: Are the package dimensions identical across all three parts?

A: The footprint dimensions are identical (7.00mm x 5.00mm). The seated height of the Taitien part is 0.05mm lower (1.85mm vs. 1.90mm), which is negligible for standard PCB assembly processes.
