Substitute Part Grouping Explanation

Substitute parts for the 290PGLF are identified based on the following critical parameters that determine functional compatibility:

• Package / Case: 20-TSSOP (0.173", 4.40mm Width) — ensures PCB footprint compatibility
• Voltage - Supply: 3.135V ~ 3.465V — maintains power supply compatibility
• Operating Temperature: 0°C ~ 70°C — ensures thermal operating range alignment
• Frequency - Max: 200MHz — confirms maximum frequency capability
• Output Type: CMOS — maintains signal interface compatibility
• Mounting Type: Surface Mount — preserves assembly process compatibility
• PLL with Bypass: Yes — ensures functional feature availability
• Input: Clock, Crystal — confirms input source flexibility

The Input:Output Ratio parameter (1:8 for 290PGLF versus 1:6 for 291PGLF) represents a functional difference in frequency multiplication capability and does not prevent substitution when the application's specific frequency requirements are met through alternative ratio configurations.

Parameter Comparison

Engineering Selection Recommendations

The 291PGLF serves as a parametric equivalent substitute for the obsolete 290PGLF. Both components share identical electrical specifications across supply voltage, operating temperature range, maximum frequency, and package form factor. The primary distinction is product status: the 291PGLF is Active, providing ongoing manufacturer support and availability, whereas the 290PGLF is Obsolete.

The 291PGLF carries ROHS3 compliance certification, meeting current environmental and regulatory requirements for new designs and manufacturing processes. The Input:Output Ratio difference (1:6 versus 1:8) requires verification that the application's frequency synthesis requirements can be satisfied through the alternative multiplication ratio. Both components maintain identical Moisture Sensitivity Level (MSL 1) and share the same supply voltage and thermal operating specifications.

Frequently Asked Questions (FAQ)

Q: Can the 291PGLF directly replace the 290PGLF without PCB modifications?

A: Yes, the 291PGLF uses the identical 20-TSSOP package footprint, enabling direct PCB placement without layout changes. Pin compatibility and electrical interface characteristics are maintained.

Q: What is the significance of the different Input:Output Ratio (1:8 versus 1:6)?

A: The Input:Output Ratio defines the frequency multiplication capability. The 290PGLF multiplies input frequency by up to 8x, while the 291PGLF multiplies by up to 6x. Application-specific frequency requirements must be verified to confirm the 1:6 ratio meets system needs.

Q: Are there supply voltage or thermal operating range differences?

A: No. Both the 290PGLF and 291PGLF operate within identical supply voltage (3.135V ~ 3.465V) and temperature ranges (0°C ~ 70°C), ensuring compatibility in existing power distribution and thermal management designs.

Q: What compliance advantage does the 291PGLF provide?

A: The 291PGLF is ROHS3 compliant, meeting current environmental regulations. The 290PGLF RoHS status is not specified. For new designs and manufacturing environments subject to RoHS requirements, the 291PGLF is the appropriate selection.

Q: Is the 291PGLF available in the same packaging specification?

A: Yes. Both components are supplied in 20-TSSOP (0.173", 4.40mm Width) surface mount packages with identical Moisture Sensitivity Level (MSL 1 - Unlimited).

Q: Why is the 290PGLF classified as Obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The 291PGLF, as an Active product within the same VersaClock® series, represents the current manufacturing alternative for equivalent clock synthesis functionality.
