Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AX5PAF1-491.5200C is determined by the following critical parameters:

• Frequency: 491.52 MHz (exact match required)
• Output Type: LVPECL (exact match required)
• Function: Enable/Disable (exact match required)
• Package / Case: 8-SMD, No Lead (exact match required)
• Size / Dimension: 5.00mm x 3.20mm (exact match required)
• Operating Temperature Range: -40°C ~ 85°C (exact match required)
• Frequency Stability: ±20ppm (exact match required)

The substitute part AX5PBF1-491.5200C matches all critical parameters with one exception: the supply voltage is 2.5V instead of 3.3V. This voltage difference represents a functional variation that must be evaluated against specific circuit requirements.

Parameter Comparison

Engineering Selection Recommendations

Both the AX5PAF1-491.5200C and AX5PBF1-491.5200C are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory standards. Both parts carry MSL Level 1 (Unlimited) moisture sensitivity ratings, indicating equivalent handling and storage requirements.

The primary distinction between these parts is the supply voltage specification: 3.3V for the AX5PAF1-491.5200C and 2.5V for the AX5PBF1-491.5200C. Selection between these parts depends on the power supply architecture of the target application. The AX5PBF1-491.5200C is currently available in inventory (1107 Pcs New Original In Stock) and represents an active alternative to the discontinued AX5PAF1-491.5200C.

Frequently Asked Questions (FAQ)

Q: Can the AX5PBF1-491.5200C directly replace the AX5PAF1-491.5200C?

A: Direct replacement is possible only if the application circuit operates at 2.5V supply voltage. The substitute part maintains identical frequency, output type, function, package, and thermal specifications. If the original design requires 3.3V operation, circuit modification is necessary.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both parts share the same package type (8-SMD, No Lead), footprint dimensions (5.00mm x 3.20mm), and maximum seated height (1.50mm), ensuring PCB layout compatibility.

Q: What are the key parameters that must match for substitution?

A: Frequency (491.52 MHz), output type (LVPECL), function (Enable/Disable), package configuration (8-SMD, No Lead), operating temperature range (-40°C ~ 85°C), and frequency stability (±20ppm) must remain constant. Supply voltage may differ based on circuit requirements.

Q: Are both parts compliant with current environmental regulations?

A: Yes. Both the AX5PAF1-491.5200C and AX5PBF1-491.5200C are ROHS3 Compliant and REACH Unaffected, meeting current environmental standards for electronic components.

Q: What is the moisture sensitivity level for these oscillators?

A: Both parts carry MSL Level 1 (Unlimited), indicating no moisture sensitivity restrictions and unlimited shelf life under standard storage conditions.
