Renesas 342MIPLF Clock/Frequency Synthesizer IC - Equivalent & Substitute Parts

Part Overview

The Renesas 342MIPLF is a Clock/Frequency Synthesizer IC operating at 200MHz maximum frequency, housed in an 8-SOIC package. This component belongs to the VersaClock® series and features integrated PLL functionality with clock and crystal input options, delivering LVCMOS output signals. The product is currently classified as obsolete, making identification of functionally compatible alternatives essential for ongoing system support and new design implementations where legacy specifications must be maintained or adapted.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 342MIPLF requires evaluation against the following critical parameters that define functional compatibility:

Mandatory Compatibility Criteria:

• PLL functionality (must be present)
• Input capability (clock or crystal input support)
• Output signal type (LVCMOS standard)
• Operating temperature range (-40°C ~ 85°C minimum)
• Surface mount technology
• Moisture sensitivity level (MSL 1 preferred for unlimited shelf life)

Functional Flexibility Parameters:

• Maximum frequency (substitute may operate at different frequency)
• Supply voltage range (substitute may require different voltage)
• Package type (substitute may use different surface mount package)
• Number of circuits (substitute may provide multiple circuits)
• Input:Output ratio (substitute may have different multiplication/division ratio)

The identified substitute part 5L2503-000NVGI shares core PLL and signal processing architecture with the 342MIPLF but operates in a different frequency domain and packaging configuration, requiring design-level evaluation for specific applications.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The 342MIPLF is classified as obsolete, while the 5L2503-000NVGI is active production. Active status ensures ongoing availability, manufacturing consistency, and technical support from Renesas Electronics Corporation.

Compliance and Certification: Both parts maintain identical REACH status (REACH Unaffected) and ECCN classification (EAR99), ensuring equivalent regulatory compliance for export and supply chain purposes. Both components carry MSL 1 rating, providing unlimited shelf life under standard storage conditions.

Functional Differences Requiring Design Evaluation: The 5L2503-000NVGI operates at significantly lower maximum frequency (32.768kHz versus 200MHz) and requires lower supply voltage (1.71V ~ 1.89V versus 3.15V ~ 3.45V). The substitute provides three output circuits compared to the single circuit of the main part. These differences necessitate circuit-level analysis to determine applicability to specific timing and frequency requirements.

Frequently Asked Questions (FAQ)

Q: Can the 5L2503-000NVGI directly replace the 342MIPLF in existing designs?

A: Direct replacement is not possible without design modification. The substitute operates at 32.768kHz maximum frequency, suitable for real-time clock and low-frequency timing applications, whereas the 342MIPLF operates at 200MHz for high-speed clock synthesis. Supply voltage requirements also differ significantly (1.71V ~ 1.89V versus 3.15V ~ 3.45V). Application-specific evaluation is required.

Q: What are the key compatibility factors between these parts?

A: Both components feature integrated PLL functionality, LVCMOS output signaling, identical operating temperature range (-40°C ~ 85°C), surface mount technology, and MSL 1 moisture sensitivity rating. These shared characteristics define the substitution relationship, though frequency domain and voltage requirements differ substantially.

Q: Why does the substitute part have three circuits instead of one?

A: The 5L2503-000NVGI is designed as a multi-output clock generator for applications requiring multiple synchronized timing signals. The 342MIPLF provides single-circuit synthesis. The additional circuits in the substitute may provide design flexibility but require appropriate circuit design integration.

Q: Are there package compatibility considerations?

A: Yes. The 342MIPLF uses 8-SOIC packaging (0.154", 3.90mm width), while the 5L2503-000NVGI uses 12-UFDFN packaging (2.5x2.5mm). These are physically distinct packages requiring different PCB footprints and layout considerations. Mechanical redesign is necessary for substitution.

Q: What input options does each part support?

A: The 342MIPLF accepts both clock and crystal inputs, providing flexibility in timing source selection. The 5L2503-000NVGI accepts crystal input only. Applications requiring external clock input cannot use the substitute without alternative timing architecture.

Q: How do the input:output ratios differ?

A: The 342MIPLF provides 1:2 multiplication (input frequency doubled at output), while the 5L2503-000NVGI provides 1:3 multiplication. This difference affects the relationship between input crystal frequency and output clock frequency, requiring recalculation of timing parameters for any substitution scenario.
