Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 512MILFT is determined by the following critical parameters:

• Package compatibility: 8-SOIC (0.154", 3.90mm Width) form factor
• Electrical interface: Clock and Crystal input support with CMOS output capability
• PLL architecture: Integrated PLL with bypass functionality
• Input:Output ratio: 1:2 multiplier configuration
• Supply voltage range: 3V ~ 5.5V operation
• Temperature range: -40°C ~ 85°C minimum specification
• Single circuit configuration
• RoHS3 compliance and MSL Level 1 rating

The identified substitute parts meet these core substitution criteria while maintaining pin-compatible packaging and functional equivalence for clock generation and multiplication applications.

Parameter Comparison

Engineering Selection Recommendations

NB3N502DG and NB3N502DR2G represent the primary substitutes for the obsolete 512MILFT. Both onsemi parts are Active status devices with identical electrical specifications, pin-compatible 8-SOIC packaging, and full compliance with RoHS3 and REACH requirements. The NB3N502 series provides enhanced frequency capability (190MHz versus 160MHz), supporting the original 1:2 input:output ratio with additional output format flexibility (CMOS and TTL). Selection between NB3N502DG (Tube packaging) and NB3N502DR2G (Tape & Reel packaging) depends on procurement and assembly requirements.

The 5P35021-000NDG28 is identified as a manufacturer-recommended alternative from Renesas Electronics Corporation with Active product status. Detailed electrical and packaging specifications for this part are not provided in the available data; verification of functional equivalence and package compatibility is required before selection.

Frequently Asked Questions (FAQ)

Q: Can NB3N502DG and NB3N502DR2G be used interchangeably with 512MILFT?

A: Yes, both NB3N502 variants meet the core substitution criteria: identical 8-SOIC package, matching supply voltage range (3V ~ 5.5V), equivalent operating temperature range (-40°C ~ 85°C), PLL with bypass architecture, and 1:2 input:output ratio. The primary difference is packaging format (Tube versus Tape & Reel). The higher maximum frequency rating (190MHz) of the NB3N502 series provides additional performance margin.

Q: What is the difference between NB3N502DG and NB3N502DR2G?

A: Both parts are electrically identical onsemi PLL Clock Multiplier ICs with 190MHz maximum frequency. The distinction is packaging: NB3N502DG is supplied in Tube format, while NB3N502DR2G is supplied in Tape & Reel (TR) format. Selection depends on assembly line requirements and procurement preferences.

Q: Are there packaging considerations when substituting for 512MILFT?

A: The 512MILFT is available in Cut Tape (CT) and Digi-Reel packaging. Substitute parts NB3N502DG and NB3N502DR2G use standard Tube and Tape & Reel packaging respectively. Verify that your assembly process accommodates the selected packaging format.

Q: What compliance certifications apply to the substitute parts?

A: Both NB3N502DG and NB3N502DR2G are ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited), matching the original 512MILFT specifications. Both are REACH Unaffected and carry EAR99 ECCN classification.

Q: Is the 5P35021-000NDG28 a suitable substitute?

A: The 5P35021-000NDG28 is manufacturer-recommended by Renesas Electronics Corporation and maintains Active product status. However, complete electrical and packaging specifications are not provided in the available documentation. Detailed datasheet review and compatibility verification are necessary before implementation.
