Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the PI6C41204LE are categorized based on electrical parameter compatibility and product status. The substitution logic is strictly defined by the following key parameters:

Critical Matching Parameters:

• Input:Output Ratio: 2:4
• Input Logic Levels: LVCMOS, LVTTL
• Output Logic Levels: LVPECL
• Package / Case: 20-TSSOP (0.173", 4.40mm Width)
• Mounting Type: Surface Mount
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Substitution Categories:

Direct Equivalents (Parametric Match): Parts that maintain identical electrical specifications and operating temperature range (0°C ~ 70°C), with identical frequency maximum (266 MHz) and supply voltage range (3.135V ~ 3.465V). These parts are pin-compatible and functionally interchangeable without design modification.

Direct Substitutes (Active Status): Parts that maintain identical electrical specifications but may differ in packaging format (Tape & Reel, Tube, Cut Tape) or have extended operating temperature ranges (-40°C ~ 85°C). These parts are functionally equivalent with identical frequency and voltage specifications.

Upgrade Substitutes (Enhanced Temperature Range): Parts that maintain identical electrical specifications with extended operating temperature range (-40°C ~ 85°C), providing broader environmental compatibility while preserving all other electrical parameters.

Performance-Enhanced Alternatives (Manufacturer Recommended): Parts with increased frequency capability (1 GHz vs. 266 MHz) and extended operating temperature range (-40°C ~ 85°C). These parts provide superior performance headroom and are recommended for new designs requiring higher clock distribution speeds.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Identical Specifications): Select 8535AG-01LF, 8535AG-01LFT, or 8535AG-31LF for direct substitution when operating temperature range of 0°C ~ 70°C is acceptable. These parts maintain identical electrical specifications, frequency capability, and supply voltage range. All three are ROHS3 compliant with MSL rating of 1 (Unlimited). Packaging format selection depends on procurement requirements: 8535AG-01LFT (Tape & Reel), 8535AG-31LF (Tube), or 8535AG-01LF (standard packaging).

For Extended Temperature Range Applications: Select 8535AGI-01LF or 8535AGI-01LFT when operating temperature range of -40°C ~ 85°C is required. These parts maintain identical electrical specifications and frequency capability while providing broader environmental compatibility. Both are ROHS3 compliant with MSL rating of 1 (Unlimited). Packaging format selection: 8535AGI-01LF (Tube) or 8535AGI-01LFT (Cut Tape & Digi-Reel).

For Performance-Enhanced Applications: Select MC100ES6535EJ or MC100ES6535EJR2 when higher clock distribution frequency (1 GHz) is required. These parts provide extended operating temperature range (-40°C ~ 85°C) and broader supply voltage range (3.135V ~ 3.8V). Both are ROHS3 compliant. Note: MSL rating is 3 (168 Hours), requiring controlled storage conditions. These parts are manufacturer-recommended upgrades for new designs.

Compliance Considerations: All substitute parts maintain ROHS3 compliance and REACH unaffected status, matching the original PI6C41204LE specifications. All parts are classified under ECCN EAR99 and HTSUS 8542.39.0001.

Frequently Asked Questions (FAQ)

Q: Can I use 8535AG-01LF as a direct replacement for PI6C41204LE? A: Yes. The 8535AG-01LF maintains identical electrical specifications including 2:4 input:output ratio, LVCMOS/LVTTL input, LVPECL output, 266 MHz maximum frequency, and 3.135V ~ 3.465V supply voltage. Both are packaged in 20-TSSOP and are ROHS3 compliant. The operating temperature range is identical (0°C ~ 70°C).

Q: What is the difference between 8535AG-01LF and 8535AGI-01LF? A: The primary difference is operating temperature range. The 8535AG-01LF operates from 0°C ~ 70°C, while the 8535AGI-01LF operates from -40°C ~ 85°C. All other electrical specifications are identical. Select 8535AGI-01LF for applications requiring extended temperature range operation.

Q: Why would I choose MC100ES6535EJ over the 8535A series? A: The MC100ES6535EJ provides higher maximum frequency (1 GHz vs. 266 MHz) and extended operating temperature range (-40°C ~ 85°C). This part is suitable for new designs requiring higher clock distribution speeds. The supply voltage range is also broader (3.135V ~ 3.8V). Note that MSL rating is 3 (168 Hours), requiring controlled storage.

Q: Are all substitute parts pin-compatible with PI6C41204LE? A: Yes. All substitute parts use the identical 20-TSSOP package format (0.173", 4.40mm Width) with surface mount configuration, ensuring mechanical and electrical pin compatibility.

Q: What packaging options are available for the 8535A series? A: The 8535A series is available in multiple packaging formats: Tape & Reel (TR), Tube, and Cut Tape (CT) & Digi-Reel. Select based on procurement and assembly requirements.

Q: Do all substitute parts have the same RoHS and REACH compliance? A: Yes. All substitute parts are ROHS3 compliant and REACH unaffected, matching the original PI6C41204LE specifications.

Q: What is the significance of MSL rating differences? A: The 8535A series has MSL rating of 1 (Unlimited), allowing unlimited shelf life without moisture bake-out. The MC100ES6535 series has MSL rating of 3 (168 Hours), requiring controlled storage conditions and moisture bake-out procedures before assembly if storage exceeds 168 hours.
