Equivalent & Substitute Parts for 830154AMI-08LF

Part Overview

The 830154AMI-08LF is a Clock Fanout Buffer (Distribution) IC manufactured by Renesas, designed for 1:4 clock distribution applications with a maximum frequency of 160 MHz. This device features LVCMOS input and output signaling, operates across multiple supply voltage ranges (1.4V to 3.465V), and is housed in an 8-SOIC surface mount package.

The 830154AMI-08LF is classified as Obsolete, making it necessary to identify equivalent and substitute components for new designs or ongoing production requirements. Equivalent parts maintain identical or superior electrical and mechanical specifications, while substitute parts provide functional alternatives within acceptable parameter tolerances for clock distribution applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the 830154AMI-08LF is determined by the following critical parameters:

Functional Requirements:

• Fanout Buffer (Distribution) topology with 1:4 input-to-output ratio
• LVCMOS input and output compatibility
• Single circuit configuration

Electrical Requirements:

• Maximum frequency capability of 160 MHz or greater
• Supply voltage range compatibility with 1.4V minimum and 3.465V maximum
• Operating temperature range of -40°C to 85°C

Mechanical Requirements:

• 8-SOIC surface mount package with 0.154" (3.90mm) width
• Pin-compatible footprint

Substitute parts are grouped into two categories:

1. Parametric Equivalent: Parts matching all electrical specifications and frequency rating (160 MHz)
2. Functional Substitute: Parts exceeding frequency specifications (180 MHz) with expanded supply voltage ranges and enhanced signal compatibility

Engineering Selection Recommendations

NB3U1548CDG (onsemi) - Recommended Primary Substitute

The NB3U1548CDG is a parametric equivalent offering identical electrical specifications to the 830154AMI-08LF with the advantage of Active product status. This part maintains the 160 MHz maximum frequency, 1:4 fanout configuration, and LVCMOS signal compatibility. The NB3U1548CDG provides an expanded supply voltage range (1.4V to 3.465V) and achieves ROHS3 compliance with REACH Unaffected status. The MSL rating of 1 (Unlimited) provides superior moisture handling characteristics. Pin-compatible 8-SOIC packaging ensures direct footprint compatibility.

PI6C10804WE (Diodes Incorporated) - Alternative Functional Substitute

The PI6C10804WE provides enhanced frequency capability at 180 MHz, exceeding the 160 MHz requirement of the original part. This device supports both LVCMOS and LVTTL signal types, offering greater system flexibility. The supply voltage range of 1.4V to 2.7V covers the primary operating range of the 830154AMI-08LF. The PI6C10804WE is ROHS3 compliant with REACH Unaffected status and MSL rating of 1 (Unlimited). However, this part is Discontinued at DiGi Electronics, which may impact long-term availability. The 8-SOIC package maintains mechanical compatibility.

Compliance Considerations

Both substitute parts achieve ROHS3 compliance and REACH Unaffected status, addressing environmental regulatory requirements. The original 830154AMI-08LF is RoHS non-compliant and has Vendor Undefined REACH status. Selection of either substitute part improves regulatory compliance posture for new designs or production transitions.

Frequently Asked Questions (FAQ)

Q: Can the NB3U1548CDG directly replace the 830154AMI-08LF in existing designs?

A: Yes. The NB3U1548CDG is pin-compatible in the 8-SOIC package and maintains identical electrical specifications for the 1:4 fanout buffer function. The expanded supply voltage range (1.4V to 3.465V) encompasses all operating conditions of the original part. No circuit modifications are required.

Q: What is the primary advantage of the PI6C10804WE over the NB3U1548CDG?

A: The PI6C10804WE operates at 180 MHz maximum frequency, compared to 160 MHz for both the original part and the NB3U1548CDG. This provides additional frequency margin for clock distribution applications. The PI6C10804WE also supports both LVCMOS and LVTTL input/output signaling, offering greater system integration flexibility.

Q: Are there supply voltage compatibility concerns when substituting these parts?

A: The NB3U1548CDG supply voltage range (1.4V to 3.465V) fully encompasses the 830154AMI-08LF operating range. The PI6C10804WE range (1.4V to 2.7V) covers the primary operating voltages but does not extend to the 3.135V to 3.465V range of the original part. Verify system supply voltages before selecting the PI6C10804WE for applications requiring operation above 2.7V.

Q: What is the impact of the NB3U1548CDG Active product status compared to the Discontinued PI6C10804WE?

A: Active product status indicates ongoing manufacturing and long-term availability support from onsemi. The PI6C10804WE Discontinued at DiGi Electronics status indicates limited future availability through distribution channels. For new designs or extended production runs, the NB3U1548CDG provides superior supply chain continuity.

Q: Do the substitute parts maintain the same operating temperature range?

A: Yes. Both the NB3U1548CDG and PI6C10804WE operate across the -40°C to 85°C temperature range, matching the 830154AMI-08LF specification. No thermal design modifications are necessary.

Q: How do RoHS and REACH compliance differences affect part selection?

A: The 830154AMI-08LF is RoHS non-compliant with undefined REACH status. Both substitute parts achieve ROHS3 compliance and REACH Unaffected status. For applications subject to environmental regulations or customer compliance requirements, either substitute part provides improved regulatory alignment. The NB3U1548CDG is recommended for designs requiring certified compliance documentation.

Q: Are the 8-SOIC packages mechanically identical?

A: Yes. All three parts use the 8-SOIC (0.154", 3.90mm Width) package specification. PCB footprints, solder reflow profiles, and mechanical assembly processes are directly compatible. No layout or manufacturing process changes are required.
