Substitute Part Grouping Explanation

Substitution eligibility for the 281PGILF is determined by strict alignment across the following critical parameters:

• Package and Pinout: 16-TSSOP surface mount package with identical physical dimensions (0.173", 4.40mm Width)
• Functional Specifications: Clock/Frequency Synthesizer with 200MHz maximum frequency, 1:3 input-to-output ratio, and CMOS output
• PLL Architecture: Integrated PLL with bypass capability
• Input/Output Configuration: Clock and crystal input support, single circuit, non-differential input and output
• Supply Voltage Range: 3.135V ~ 3.465V operating range
• Divider/Multiplier Capability: Both divider and multiplier functions present
• Moisture Sensitivity: MSL 1 classification

The 281PGLF qualifies as a direct substitute based on identical electrical specifications, package configuration, and functional architecture. The primary distinction is product status: the 281PGLF is active and available, whereas the 281PGILF is obsolete.

Parameter Comparison

Engineering Selection Recommendations

The 281PGLF is the direct active equivalent for the obsolete 281PGILF. All electrical and mechanical parameters are identical, ensuring pin-for-pin and functional compatibility within existing PCB designs.

Substitution Considerations:

• Operating Temperature Range: The 281PGLF operates within 0°C ~ 70°C, compared to the 281PGILF range of -40°C ~ 85°C. Applications requiring extended low-temperature operation below 0°C or high-temperature operation above 70°C must evaluate thermal requirements against the substitute's specifications.

• Compliance Status: The 281PGLF carries ROHS3 compliance certification, providing enhanced regulatory alignment for new designs and manufacturing environments subject to RoHS directives.

• Supply Chain Availability: The 281PGLF is actively manufactured and stocked (875 Pcs available), whereas the 281PGILF is obsolete with limited remaining inventory (648 Pcs). Transition to the 281PGLF ensures long-term component availability.

Frequently Asked Questions (FAQ)

Q: Can the 281PGLF be used as a direct replacement for the 281PGILF in existing designs?

A: Yes. The 281PGLF is electrically and mechanically identical to the 281PGILF across all specified parameters, including package type, frequency rating, supply voltage, and functional architecture. No PCB modifications are required.

Q: What is the primary difference between these two parts?

A: The 281PGILF is obsolete, while the 281PGLF is an active product. The 281PGLF also features a narrower operating temperature range (0°C ~ 70°C versus -40°C ~ 85°C) and carries ROHS3 compliance certification.

Q: Are there any thermal or environmental limitations when substituting the 281PGLF for the 281PGILF?

A: The 281PGLF operates within 0°C ~ 70°C. If your application requires operation below 0°C or above 70°C, the substitute's temperature range must be evaluated against your system requirements. For applications within the 0°C ~ 70°C window, no thermal limitations apply.

Q: Is the 16-TSSOP package identical between both parts?

A: Yes. Both parts use the same 16-TSSOP surface mount package with dimensions of 0.173" × 4.40mm width. Footprint and land pattern compatibility is assured.

Q: Does the 281PGLF support the same input and output configurations?

A: Yes. Both parts support identical input types (Clock, Crystal) and output type (CMOS), with the same 1:3 input-to-output ratio and integrated PLL with bypass capability.

Q: What is the moisture sensitivity classification for the 281PGLF?

A: The 281PGLF carries MSL 1 (Unlimited) classification, identical to the 281PGILF. This indicates minimal moisture sensitivity and unlimited shelf life under standard storage conditions.
