Key Parameters

Substitute Part Grouping Explanation

The AX5PAF1-300.0000T qualifies as a parametric equivalent to the AX5PAF4-300.0000T based on the following critical substitution criteria:

Electrical Parameters (Identical):

• Frequency: 300 MHz
• Output: LVPECL
• Supply Voltage: 3.3V
• Function: Enable/Disable
• Frequency Stability: ±20ppm
• Operating Temperature: -40°C ~ 85°C
• Maximum Supply Current: 110mA
• Maximum Disable Current: 100mA

Mechanical Parameters (Identical):

• Package: 8-SMD, No Lead
• Dimensions: 5.00mm x 3.20mm x 1.50mm (max height)
• Mounting Type: Surface Mount

Compliance & Certifications (Identical):

• RoHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)
• REACH Status: REACH Unaffected
• ECCN: EAR99
• HTSUS: 8542.39.0001

The primary difference is packaging format: AX5PAF4-300.0000T uses standard packaging, while AX5PAF1-300.0000T is supplied in Cut Tape (CT) & Digi-Reel® format. This distinction affects procurement and handling but does not impact electrical or mechanical performance.

Parameter Comparison

Engineering Selection Recommendations

Both the AX5PAF4-300.0000T and AX5PAF1-300.0000T are Active products from Abracon LLC with identical electrical and mechanical specifications. Selection between these parts should be based on procurement requirements and supply chain considerations:

AX5PAF4-300.0000T is suitable for standard procurement channels with 917 units currently in stock.

AX5PAF1-300.0000T is suitable for high-volume automated assembly operations utilizing tape-and-reel handling, with 838 units currently in stock.

Both parts meet ROHS3 compliance and REACH requirements, ensuring regulatory compatibility for industrial and commercial applications. The identical frequency stability (±20ppm), operating temperature range (-40°C ~ 85°C), and current specifications (110mA max supply, 100mA max disable) confirm functional interchangeability in circuit designs.

Frequently Asked Questions (FAQ)

Q: Can AX5PAF1-300.0000T be used as a direct replacement for AX5PAF4-300.0000T?

A: Yes. Both parts are electrically and mechanically identical. The only difference is packaging format (Cut Tape & Digi-Reel® versus standard packaging). Pin configuration, electrical performance, and physical footprint are identical, enabling direct substitution in PCB designs.

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

A: AX5PAF4-300.0000T uses standard packaging suitable for manual handling and small-quantity procurement. AX5PAF1-300.0000T is supplied in Cut Tape (CT) & Digi-Reel® format, optimized for automated pick-and-place assembly equipment in high-volume manufacturing environments.

Q: Are there any compliance or certification differences?

A: No. Both parts carry identical certifications: ROHS3 Compliant, REACH Unaffected status, Moisture Sensitivity Level 1 (Unlimited), ECCN EAR99, and HTSUS 8542.39.0001.

Q: What are the critical electrical parameters for substitution?

A: The critical parameters are frequency (300 MHz), output type (LVPECL), supply voltage (3.3V), frequency stability (±20ppm), and operating temperature range (-40°C ~ 85°C). Both parts match all these specifications.

Q: Can these parts be used interchangeably on the same PCB?

A: Yes. The 8-SMD, No Lead package with identical dimensions (5.00mm x 3.20mm x 1.50mm max height) ensures mechanical and electrical compatibility. No PCB redesign is required.
