Substitute Part Grouping Explanation

Substitution eligibility for the 276PGILF is determined by the following critical parameters:

• Package Compatibility: 16-TSSOP (0.173", 4.40mm Width) surface mount package
• Functional Type: Clock/Frequency Synthesizer with integrated PLL and bypass capability
• Frequency Range: 200MHz maximum operating frequency
• Input/Output Configuration: Crystal input with CMOS output, 1:3 input-to-output ratio
• Supply Voltage: 3.135V ~ 3.465V operating range
• Electrical Characteristics: Single circuit, non-differential input and output

The Renesas 281PGLF qualifies as a substitute based on matching all critical electrical and mechanical parameters. The primary distinction is product status and operating temperature range, which do not affect functional substitutability in applications designed for the 276PGILF.

Parameter Comparison

Engineering Selection Recommendations

The Renesas 281PGLF is the manufacturer-recommended substitute for the obsolete 276PGILF. Both components share identical electrical specifications, package geometry, and functional architecture within the VersaClock® family.

The 281PGLF carries Active product status and RoHS3 compliance certification, providing long-term availability and regulatory alignment for new designs and production continuity. The operating temperature range of the 281PGLF (0°C ~ 70°C) is narrower than the 276PGILF (-40°C ~ 85°C); applications requiring extended temperature operation below 0°C or above 70°C must evaluate system thermal requirements against this specification.

The 281PGLF accepts both clock and crystal inputs, providing enhanced flexibility compared to the 276PGILF crystal-only input specification. This expanded input capability does not affect substitutability for existing 276PGILF applications.

Frequently Asked Questions (FAQ)

Q: Can the 281PGLF directly replace the 276PGILF in existing designs?

A: Yes. Both parts share identical package geometry (16-TSSOP), supply voltage range (3.135V ~ 3.465V), maximum frequency (200MHz), input-to-output ratio (1:3), and CMOS output configuration. Pin-for-pin compatibility is maintained.

Q: What is the primary difference between these parts?

A: The 276PGILF is obsolete; the 281PGLF is active production. The 281PGLF has a narrower operating temperature range (0°C ~ 70°C versus -40°C ~ 85°C) and accepts both clock and crystal inputs versus crystal-only input on the 276PGILF.

Q: Are there temperature-related constraints for substitution?

A: Applications requiring operation below 0°C or above 70°C must verify that system thermal management and operating conditions remain within the 281PGLF specification. The 276PGILF supports extended temperature operation to -40°C and 85°C.

Q: Does the 281PGLF's dual input capability (clock and crystal) affect compatibility?

A: No. The 281PGLF maintains full backward compatibility with crystal input applications designed for the 276PGILF. The additional clock input option provides design flexibility without affecting existing circuit operation.

Q: Are regulatory certifications equivalent?

A: Both parts carry REACH Unaffected status and EAR99 ECCN classification. The 281PGLF includes RoHS3 compliance certification, providing enhanced regulatory alignment for current manufacturing standards.
