Renesas 341MIPLF Clock/Frequency Synthesizer IC Equivalent & Substitute Parts

Part Overview

The Renesas 341MIPLF is a Clock/Frequency Synthesizer IC designed for 200MHz operation in an 8-SOIC surface mount package. This component belongs to the VersaClock® series and features integrated PLL functionality with LVCMOS output. The 341MIPLF is currently classified as obsolete, making identification of functionally compatible substitute parts essential for ongoing system support, design updates, and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete 341MIPLF requires evaluation based on the following critical parameters:

Functional Compatibility Criteria:

• PLL capability (Yes/No)
• Input type support (Clock, Crystal, or both)
• Output signal type (LVCMOS)
• Operating temperature range (-40°C ~ 85°C minimum)
• Supply voltage compatibility

Physical Compatibility Criteria:

• Surface mount technology
• Package footprint and pin count
• Moisture sensitivity level

Regulatory & Compliance Criteria:

• REACH compliance status
• ECCN classification
• RoHS compliance status

The substitute part 5L2503-000NVGI is identified as a manufacturer-recommended alternative. However, this substitute exhibits significant functional differences from the 341MIPLF, including different frequency specifications, circuit count, and input/output ratios. Substitution requires careful application-level verification.

Parameter Comparison

Engineering Selection Recommendations

Substitution Feasibility Assessment:

The 5L2503-000NVGI is listed as a manufacturer-recommended substitute for the 341MIPLF. However, direct substitution is not recommended without comprehensive application-level verification due to the following factors:

Limiting Factors:

• Maximum frequency specification differs significantly (200MHz vs. 32.768kHz)
• Supply voltage ranges are incompatible (3.15V-3.45V vs. 1.71V-1.89V)
• Package footprints differ (8-SOIC vs. 12-UFDFN), requiring PCB redesign
• Input type support differs (Clock/Crystal vs. Crystal only)
• Circuit count and input/output ratios are different

Compliance Advantages:

• Both parts maintain REACH Unaffected status
• Both parts share EAR99 export classification
• Both parts have MSL 1 (Unlimited) rating
• The 5L2503-000NVGI provides documented ROHS3 compliance

Selection Guidance: For applications requiring the specific frequency, voltage, and functional characteristics of the 341MIPLF, direct substitution with the 5L2503-000NVGI is not suitable. Alternative clock/timing components from Renesas or other manufacturers with matching electrical specifications should be evaluated. If the 5L2503-000NVGI is considered, application requirements must be re-evaluated against its 32.768kHz maximum frequency and 1.71V-1.89V supply voltage specifications.

Frequently Asked Questions (FAQ)

Q: Can the 5L2503-000NVGI be used as a direct drop-in replacement for the 341MIPLF?

A: No. While both are Renesas clock/timing components with PLL capability, they have fundamentally different electrical specifications. The 5L2503-000NVGI operates at a maximum frequency of 32.768kHz compared to the 341MIPLF's 200MHz, and requires a supply voltage of 1.71V-1.89V versus 3.15V-3.45V. Additionally, the package types differ (12-UFDFN vs. 8-SOIC), requiring PCB redesign. Application-level verification is mandatory before considering this substitute.

Q: What are the key differences in functional capability between these parts?

A: The 341MIPLF is a Clock/Frequency Synthesizer with support for both Clock and Crystal inputs, a 1:1 input/output ratio, and multiplier capability. The 5L2503-000NVGI is a Clock Generator with Crystal input only, a 1:3 input/output ratio, and no multiplier capability. The 5L2503-000NVGI provides three output circuits compared to the 341MIPLF's single circuit.

Q: Are there package compatibility considerations?

A: Yes. The 341MIPLF uses an 8-SOIC (0.154", 3.90mm Width) package, while the 5L2503-000NVGI uses a 12-UFDFN (2.5x2.5) package. These are physically incompatible footprints, requiring PCB layout redesign if substitution is attempted.

Q: What is the significance of the 341MIPLF being classified as obsolete?

A: Obsolete status indicates the part is no longer manufactured by Renesas. This necessitates identification of alternative components for new designs, design revisions, or continued system support. The manufacturer-recommended substitute should be evaluated against specific application requirements.

Q: Do both parts meet current regulatory compliance standards?

A: Both the 341MIPLF and 5L2503-000NVGI maintain REACH Unaffected status and share EAR99 export classification. The 5L2503-000NVGI provides documented ROHS3 compliance. Both parts have MSL 1 (Unlimited) ratings, indicating no moisture sensitivity restrictions.

Q: What supply voltage considerations apply to substitution?

A: The 341MIPLF requires 3.15V-3.45V supply voltage, while the 5L2503-000NVGI requires 1.71V-1.89V. These ranges do not overlap. Any substitution attempt would require separate power supply design modifications or use of voltage regulation circuitry.

Q: Are there frequency specification constraints for substitution?

A: Yes. The 341MIPLF supports frequencies up to 200MHz, while the 5L2503-000NVGI is limited to 32.768kHz maximum frequency. Applications requiring high-frequency clock synthesis cannot use the 5L2503-000NVGI as a substitute.
