Equivalent & Substitute Parts for 8525BGLF

Part Overview

The 8525BGLF is a Clock Fanout Buffer (Distribution), Multiplexer IC manufactured by Renesas Electronics Corporation. This 2:4 clock buffer operates at a maximum frequency of 266 MHz and is packaged in a 20-TSSOP form factor. The device accepts LVCMOS and LVTTL inputs and provides LVHSTL outputs, making it suitable for clock distribution applications requiring single-ended signal conversion.

The 8525BGLF is classified as obsolete. Identifying equivalent and substitute parts is necessary to ensure continued availability for new designs, production continuity, and long-term system support.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the 8525BGLF is determined by the following critical parameters:

Primary Substitution Criteria:

• Input:Output Ratio (2:4)
• Fanout Buffer (Distribution), Multiplexer functionality
• Maximum frequency capability (minimum 266 MHz)
• Input signal compatibility (LVCMOS, LVTTL support)
• Output signal type compatibility
• Supply voltage range overlap
• Surface mount packaging

Substitution Groups:

Group 1: Direct Package and Frequency Match (20-TSSOP, 266 MHz) Parts maintaining the original 20-TSSOP package and 266 MHz maximum frequency specification:

• NB3N853501EDTG (onsemi)
• NB3N853501EDTR2G (onsemi)

Group 2: Enhanced Performance Alternative (16-VFQFN, 2 GHz) Part offering higher frequency capability and differential signal support with different package:

• 8SLVP1204ANLGI (Renesas Electronics Corporation)

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Same Package, Same Frequency):

NB3N853501EDTR2G is the preferred direct substitute. This part maintains the 20-TSSOP package and 266 MHz maximum frequency of the original 8525BGLF. The device is currently in active production status, ensuring long-term availability. It is ROHS3 compliant and carries unlimited moisture sensitivity rating. The operating temperature range extends to -40°C to 85°C, providing broader environmental coverage than the original part.

NB3N853501EDTG is an alternative direct substitute with identical electrical specifications but obsolete product status. This part should be considered only when NB3N853501EDTR2G is unavailable.

For Enhanced Performance Applications:

8SLVP1204ANLGI offers significantly higher frequency capability (2 GHz maximum) and supports differential input and output signaling (CML, LVDS, LVPECL). This part requires a different package footprint (16-VFQFN Exposed Pad) and introduces higher moisture sensitivity (MSL 3). Selection of this part is appropriate only when the application requires frequencies exceeding 266 MHz and the PCB layout can accommodate the 16-VFQFN package. The extended supply voltage range (2.375V ~ 3.63V) provides additional design flexibility.

Compliance Considerations:

All active substitute parts are ROHS3 compliant. The 8525BGLF REACH status is unaffected; all substitute parts maintain this same classification.

Frequently Asked Questions (FAQ)

Q: Can NB3N853501EDTR2G be used as a direct replacement for 8525BGLF in existing designs?

A: Yes. NB3N853501EDTR2G maintains the same 20-TSSOP package, 2:4 input:output ratio, 266 MHz maximum frequency, and supply voltage range as the 8525BGLF. The device accepts identical input signal types (LVCMOS, LVTTL) and provides compatible output signaling. The extended operating temperature range (-40°C to 85°C versus 0°C to 70°C) and active product status make this the recommended direct substitute.

Q: What is the difference between LVHSTL and LVPECL output signaling?

A: LVHSTL (Low Voltage High Speed Transceiver Logic) and LVPECL (Low Voltage Positive Emitter Coupled Logic) are different single-ended and differential output standards. The 8525BGLF provides LVHSTL outputs, while NB3N853501EDTR2G provides LVPECL outputs. Both are low-voltage standards suitable for clock distribution, but they have different impedance and signal swing characteristics. System-level compatibility depends on the receiving circuitry.

Q: Why does 8SLVP1204ANLGI have a different package than the original part?

A: The 8SLVP1204ANLGI uses a 16-VFQFN package instead of the 20-TSSOP package of the 8525BGLF. This smaller package reflects the more advanced integration and higher frequency capability (2 GHz) of the newer device. PCB layout modifications are required to accommodate this package change.

Q: Is NB3N853501EDTG still available for new designs?

A: NB3N853501EDTG is classified as obsolete. While inventory may be available from existing stock, this part should not be selected for new designs. NB3N853501EDTR2G is the recommended alternative, as it is in active production and offers the same electrical specifications with extended environmental operating range.

Q: What does MSL 3 (168 Hours) mean for the 8SLVP1204ANLGI?

A: Moisture Sensitivity Level 3 indicates that the component can be exposed to moisture for a maximum of 168 hours before soldering. This is more restrictive than the MSL 1 (Unlimited) rating of the original 8525BGLF and its direct substitutes. Proper storage and handling procedures must be followed to prevent moisture absorption, which could cause soldering defects.

Q: Can the 8SLVP1204ANLGI operate at lower frequencies if my application only requires 266 MHz?

A: Yes. The 8SLVP1204ANLGI is rated for a maximum frequency of 2 GHz but can operate at lower frequencies including 266 MHz. However, selection of this part introduces unnecessary complexity (differential signaling, smaller package, higher moisture sensitivity) if the application does not require its enhanced frequency capability. NB3N853501EDTR2G remains the more appropriate choice for 266 MHz applications.
