AX3PBF2-125.0000 Equivalent & Substitute Parts

Part Overview

The AX3PBF2-125.0000 is a 125 MHz XO (Standard) LVPECL oscillator manufactured by Abracon LLC, part of the ClearClock™ AX3 series. This surface mount crystal oscillator operates at 2.5V with enable/disable functionality, designed for applications requiring stable frequency generation with low voltage differential signaling output. The part is currently active in production with full RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Substitute parts are identified when equivalent electrical and mechanical parameters are maintained across the same product family.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AX3PBF2-125.0000 are identified based on strict equivalence of the following critical parameters:

• Frequency: 125 MHz
• Output Type: LVPECL
• Supply Voltage: 2.5V
• Frequency Stability: ±25ppm
• Operating Temperature Range: -40°C ~ 85°C
• Package / Case: 6-SMD, No Lead
• Physical Dimensions: 0.126" L x 0.098" W (3.20mm x 2.50mm)
• Height - Seated (Max): 0.043" (1.10mm)
• Current - Supply (Max): 50mA
• Current - Supply (Disable) (Max): 10µA
• Mounting Type: Surface Mount
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

The AX3PBF1-125.0000 meets all these criteria and is classified as a parametric equivalent. The only difference is packaging format (Strip vs. standard packaging), which does not affect electrical or mechanical compatibility in the application circuit.

Frequently Asked Questions (FAQ)

Q: Can AX3PBF1-125.0000 be used as a direct replacement for AX3PBF2-125.0000?

A: Yes. Both parts are parametric equivalents with identical electrical characteristics (125 MHz, LVPECL output, 2.5V supply, ±25ppm stability) and mechanical specifications (6-SMD package, 3.20mm x 2.50mm dimensions). The only difference is packaging format (Strip vs. standard), which does not affect circuit performance or PCB assembly compatibility.

Q: Are there any differences in frequency stability or temperature performance?

A: No. Both parts maintain ±25ppm frequency stability across the -40°C to 85°C operating temperature range. Electrical performance is identical.

Q: Do both parts have the same moisture sensitivity rating?

A: Yes. Both parts carry MSL 1 (Unlimited) moisture sensitivity level, indicating no moisture sensitivity restrictions for storage or handling.

Q: What is the difference between the two packaging options?

A: AX3PBF2-125.0000 uses standard packaging format, while AX3PBF1-125.0000 uses Strip packaging. Both are surface mount 6-SMD, No Lead packages with identical physical dimensions and mounting characteristics. The packaging difference relates to supply format and does not affect electrical or mechanical compatibility.

Q: Are both parts RoHS compliant?

A: Yes. Both AX3PBF2-125.0000 and AX3PBF1-125.0000 are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards.
