Substitute Part Grouping Explanation

Substitution for the AX7PBF2-1000.0000C is determined by strict equivalence across the following critical parameters:

• Frequency: 1 GHz (exact match required)
• Output Type: LVPECL (signal integrity dependent)
• Supply Voltage: 2.5V (circuit compatibility)
• Function: Enable/Disable (operational requirement)
• Frequency Stability: ±25ppm (timing tolerance)
• Operating Temperature: -40°C ~ 85°C (environmental specification)
• Package Type: 8-SMD, No Lead (PCB footprint compatibility)
• Package Dimensions: 7.00mm x 5.00mm (board layout constraint)
• Current Specifications: 94mA max, 86mA disable (power budget)

The AX7PBF1-1000.0000C meets all these criteria and qualifies as a parametric equivalent substitute.

Parameter Comparison

Engineering Selection Recommendations

Both the AX7PBF2-1000.0000C and AX7PBF1-1000.0000C are discontinued at DiGi Electronics. Selection between these parts should be based on current inventory availability and procurement lead times. Both parts carry identical electrical and mechanical specifications, ROHS3 compliance, and REACH unaffected status, making them functionally interchangeable for circuit design purposes. The AX7PBF1-1000.0000C currently maintains higher inventory levels (829 Pcs) compared to the main part (1068 Pcs), though both are subject to discontinuation constraints.

Frequently Asked Questions (FAQ)

Q: Can the AX7PBF1-1000.0000C be used as a direct replacement for the AX7PBF2-1000.0000C?

A: Yes. Both parts are identical in electrical performance, frequency output, supply voltage, enable/disable function, and package specifications. No circuit modifications are required for substitution.

Q: Are there any differences in the 8-SMD, No Lead package between these parts?

A: No. Both parts use the same 8-SMD, No Lead package with identical dimensions of 7.00mm x 5.00mm and maximum seated height of 1.90mm. PCB footprints are directly compatible.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the AX7PBF2-1000.0000C and AX7PBF1-1000.0000C are ROHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity rating.

Q: What is the significance of the frequency stability specification?

A: Both parts maintain ±25ppm frequency stability across the -40°C to 85°C operating temperature range. This specification determines timing accuracy for applications requiring precise 1 GHz clock signals.

Q: Are there any power consumption differences between these oscillators?

A: No. Both parts draw a maximum of 94mA during normal operation and 86mA in disable mode, making them equivalent for power budget calculations.
