Engineering Selection Recommendations
511MLF and 511MLFT (Renesas Electronics Corporation)
These parts provide full electrical and mechanical compatibility with the NB3N511DG. Both support 200MHz maximum frequency, matching the original specification. The 511MLF is supplied in Tube packaging, while the 511MLFT is available in Cut Tape (CT) & Digi-Reel® format. Both are ROHS3 Compliant and carry REACH Unaffected status. The operating temperature range is 0°C ~ 70°C, which is narrower than the original part's -40°C ~ 85°C range. Selection between these two should be based on packaging and procurement requirements.
511MILF (Renesas Electronics Corporation)
This part meets all core substitution criteria with identical supply voltage, PLL functionality, and package specifications. The maximum frequency rating is 160MHz, which is lower than the NB3N511DG's 200MHz specification. The operating temperature range is -40°C ~ 85°C, matching the original part. The 511MILF is suitable for applications where the 160MHz frequency ceiling is acceptable. This part is supplied in Tube packaging.
All substitute parts are ROHS3 Compliant, carry REACH Unaffected status, and are classified as obsolete, consistent with the original component's status.
Frequently Asked Questions (FAQ)
Q: Can the 511MILF be used as a direct replacement for the NB3N511DG?
A: The 511MILF is mechanically and electrically compatible in terms of package, supply voltage, and core functionality. However, its maximum frequency rating is 160MHz compared to the NB3N511DG's 200MHz. Use this substitute only if your application operates at or below 160MHz.
Q: What is the difference between 511MLF and 511MLFT?
A: Both parts are electrically identical with 200MHz maximum frequency and identical electrical specifications. The difference is packaging: 511MLF is supplied in Tube format, while 511MLFT is supplied in Cut Tape (CT) & Digi-Reel® format. Select based on your procurement and assembly process requirements.
Q: Are there temperature range considerations when substituting?
A: The 511MLF and 511MLFT operate from 0°C ~ 70°C, which is narrower than the NB3N511DG's -40°C ~ 85°C range. If your application requires operation below 0°C or above 70°C, use the 511MILF, which supports -40°C ~ 85°C.
Q: Do all substitute parts support TTL output?
A: No. The NB3N511DG supports both CMOS and TTL outputs. The Renesas substitutes (511MLF, 511MILF, 511MLFT) support CMOS output only. Verify that your application can operate with CMOS-only output before substitution.
Q: Are all parts RoHS compliant?
A: Yes. The NB3N511DG and all listed substitutes are ROHS3 Compliant and REACH Unaffected.
