AX7PAF3-100.0000C Equivalent & Substitute Parts

Part Overview

The AX7PAF3-100.0000C is a 100 MHz XO (Standard) LVPECL oscillator manufactured by Abracon LLC, part of the ClearClock™ AX7 series. This surface mount crystal oscillator operates at 3.3V with enable/disable functionality and is housed in an 8-SMD, No Lead package measuring 7.00mm x 5.00mm. The part is currently discontinued at DiGi Electronics, with 1046 units available in new original stock. Equivalent substitute parts are necessary for ongoing production, maintenance, and design flexibility when the primary part becomes unavailable.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AX7PAF3-100.0000C are qualified based on strict electrical and mechanical parameter matching:

Critical Matching 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)
• Package / Case: 8-SMD, No Lead (exact match required)
• Physical Dimensions: 7.00mm x 5.00mm (exact match required)
• Operating Temperature Range: -40°C ~ 85°C (exact match required)
• Frequency Stability: ±25ppm (exact match required)

Allowable Variations:

• Current Supply (Max): Substitute may equal or be lower than original specification
• Height - Seated (Max): Minor variations within PCB assembly tolerance
• Packaging Format: Strip or bulk packaging acceptable for equivalent functionality
• Product Status: Active status preferred for long-term availability

Parameter Comparison

Engineering Selection Recommendations

AX7PAF1-100.0000 (Parametric Equivalent - Abracon LLC)

This part is the primary substitute for the AX7PAF3-100.0000C. It maintains identical electrical specifications and physical dimensions while offering active product status. The only difference is packaging format (Strip vs. standard), which does not affect functional performance. This part is recommended for new designs and ongoing production due to its active status and equivalent performance characteristics.

ODEMDLLTNF-100.000000 (Direct Manufacturer Alternative - Taitien)

This part provides cross-manufacturer substitution with identical frequency, output type, voltage, function, and temperature range. The maximum supply current is 110mA compared to 94mA in the original specification, which remains within acceptable operating parameters for most applications. The seated height is 0.073" (1.85mm) versus 0.075" (1.90mm), representing a 0.05mm reduction that falls within standard PCB assembly tolerances. This part is suitable for applications requiring alternative sourcing or when Abracon parts are unavailable.

Frequently Asked Questions (FAQ)

Q: Can AX7PAF1-100.0000 be used as a direct replacement for AX7PAF3-100.0000C?

A: Yes. Both parts are manufactured by Abracon LLC and share identical electrical and mechanical specifications. The difference in packaging format (Strip) does not affect circuit performance or PCB assembly compatibility.

Q: What is the significance of the higher current specification (110mA) in the Taitien ODEMDLLTNF-100.000000?

A: The Taitien part specifies a maximum supply current of 110mA compared to 94mA in the Abracon parts. This represents the upper limit of current consumption under specified conditions. The higher specification does not prevent substitution; it indicates the part may consume more current under maximum operating conditions. Verify that your power supply and circuit design can accommodate this specification.

Q: Are there any physical compatibility concerns with the Taitien ODEMDLLTNF-100.000000?

A: The Taitien part has a seated height of 0.073" (1.85mm) versus 0.075" (1.90mm) for the Abracon parts. This 0.05mm difference is within standard PCB assembly tolerances and does not present physical compatibility issues for standard surface mount applications.

Q: Why is the AX7PAF3-100.0000C discontinued?

A: The AX7PAF3-100.0000C is discontinued at DiGi Electronics. The parametric equivalent AX7PAF1-100.0000 remains active and is the recommended substitute for new designs and ongoing production requirements.

Q: Do all substitute parts meet the same compliance standards?

A: Yes. All listed substitute parts are ROHS3 Compliant, carry MSL 1 (Unlimited) rating, and are REACH Unaffected, matching the compliance profile of the original AX7PAF3-100.0000C.

Q: Can these parts be used interchangeably in existing designs?

A: Yes, provided your circuit design accommodates the specified current consumption and physical dimensions. The AX7PAF1-100.0000 is the preferred substitute due to identical specifications. The Taitien ODEMDLLTNF-100.000000 is suitable when alternative sourcing is required, with verification of current supply capability in your application.
