Substitute Part Grouping Explanation

Substitution of the 180M-01LF requires evaluation against the following critical parameters that define functional equivalence:

Primary Substitution Criteria:

• PLL architecture presence (mandatory for clock generation capability)
• Input compatibility (Clock and/or Crystal input support)
• Output signal type (CMOS output requirement)
• Supply voltage overlap (minimum 3.135V ~ 5.5V range support)
• Operating temperature range (minimum 0°C ~ 70°C coverage)
• Surface mount packaging availability
• RoHS3 compliance status

Renesas Electronics 9FGV1006C001LTGI qualifies as a manufacturer-recommended substitute based on the following alignment:

• Maintains PLL-based clock generation architecture
• Supports multiple input types including Clock and Crystal inputs
• Provides CMOS output capability alongside additional output formats
• Supply voltage range (3.135V ~ 3.465V) overlaps with the original part's 3.135V ~ 5.5V specification
• Operating temperature range (-40°C ~ 85°C) exceeds the original 0°C ~ 70°C requirement
• Surface mount packaging (16-TFLGA) maintains board-level compatibility
• RoHS3 compliant with REACH unaffected status

The 9FGV1006C001LTGI represents an upgrade path offering enhanced frequency capability (200MHz, 325MHz), expanded input/output options, and improved temperature performance while maintaining core functional compatibility.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The 180M-01LF is classified as obsolete, necessitating transition to active production parts for new designs and ongoing system support. The 9FGV1006C001LTGI maintains active product status with Renesas Electronics, ensuring long-term availability and manufacturing support.

Compliance & Certification: Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for industrial and commercial applications. The substitute part's extended operating temperature range (-40°C ~ 85°C) provides enhanced environmental performance compared to the original specification (0°C ~ 70°C).

Supply Voltage Compatibility: The substitute part operates within the 3.135V ~ 3.465V range, which overlaps with the lower portion of the original part's 3.135V ~ 5.5V specification. System designs operating at 3.3V nominal supply voltage will experience full compatibility. Designs requiring operation above 3.465V will require voltage regulation or alternative part selection.

Packaging & Board Integration: The transition from 8-SOIC to 16-TFLGA packaging requires PCB layout modification. The 16-TFLGA footprint (3x3mm) is larger than the 8-SOIC package, necessitating board redesign for physical placement and routing.

Functional Enhancement: The 9FGV1006C001LTGI provides expanded frequency capability (200MHz, 325MHz) and multiple input/output signal format options, enabling broader application scope while maintaining backward compatibility with legacy 28MHz clock generation requirements through programmable configuration.

Frequently Asked Questions (FAQ)

Q: Can the 9FGV1006C001LTGI directly replace the 180M-01LF without PCB modification?

A: No. The substitute part uses 16-TFLGA packaging versus the original 8-SOIC package. PCB footprint, trace routing, and component placement require redesign. Pin-to-pin functional mapping must be verified against device datasheets before implementation.

Q: What is the supply voltage compatibility between these parts?

A: The 180M-01LF operates at 3.135V ~ 5.5V. The 9FGV1006C001LTGI operates at 3.135V ~ 3.465V. The overlapping range is 3.135V ~ 3.465V. Systems designed for 3.3V nominal supply will function with both parts. Systems requiring 5V operation cannot use the substitute without voltage regulation.

Q: Does the substitute part support the same input/output signal types?

A: The 180M-01LF accepts Clock or Crystal inputs and provides CMOS outputs. The 9FGV1006C001LTGI accepts HCSL, LVCMOS, LVDS, or Crystal inputs and provides CML, HCSL, LP-HCSL, LVCMOS, LVDS, or LVPECL outputs. The substitute offers expanded signal format compatibility while maintaining CMOS input/output capability through appropriate configuration.

Q: What is the MSL (Moisture Sensitivity Level) difference, and does it affect handling?

A: The 180M-01LF has MSL 1 (unlimited shelf life). The 9FGV1006C001LTGI has MSL 3 (168-hour floor life after moisture exposure). The substitute requires stricter moisture control during storage and assembly. Baking procedures may be necessary if the part exceeds 168 hours in ambient conditions above 30% relative humidity.

Q: Are both parts RoHS compliant?

A: Yes. Both the 180M-01LF and 9FGV1006C001LTGI are ROHS3 compliant and REACH unaffected, meeting regulatory requirements for commercial and industrial applications.

Q: What is the frequency capability difference?

A: The 180M-01LF generates 28MHz output. The 9FGV1006C001LTGI supports 200MHz and 325MHz output frequencies through programmable configuration. Legacy 28MHz operation is achievable through appropriate device programming, enabling backward compatibility in upgraded designs.

Q: Are there additional substitute options listed for the 9FGV1006C001LTGI?

A: Yes. The manufacturer identifies 9FGV1005CQ505LTGI, 9FGV1005CQ506LTGI, and 9FGV1006CQ515LTGI as additional substitutes within the same product family, offering alternative configurations and performance specifications for specific application requirements.
