- Identical package type (32-LQFP, 7x7)
- Identical input configuration (Crystal)
- Identical output configuration (PECL)
- Identical supply voltage range (3.135V ~ 5.25V)
- Identical operating temperature range (0°C ~ 70°C)
- Identical mounting type (Surface Mount)
- Identical RoHS and REACH compliance status
- Identical number of circuits (1)
- Identical input:output ratio (1:1)
- Identical differential input/output configuration (No/Yes)
Differing Parameters:
- Maximum frequency: NBC12430FAR2G operates at 800MHz; NBC12429FAR2G operates at 400MHz
- Packaging format: NBC12430FAR2G supplied in Cut Tape (CT); NBC12429FAR2G supplied in Tape & Reel (TR)

Engineering Selection Recommendations
Both NBC12430FAR2G and NBC12429FAR2G are active production parts with ROHS3 compliance and REACH unaffected status, suitable for regulated applications. Selection between these parts depends on two primary factors:
Frequency Requirement: The NBC12430FAR2G supports maximum frequency of 800MHz, while the NBC12429FAR2G supports 400MHz maximum. Select the NBC12429FAR2G only when application frequency specifications do not exceed 400MHz.
Packaging Format: The NBC12430FAR2G is supplied in Cut Tape format; the NBC12429FAR2G is supplied in Tape & Reel format. Verify packaging compatibility with assembly equipment and procurement requirements before selection.
Both parts share identical electrical specifications for supply voltage, operating temperature, input/output configuration, and package footprint, ensuring functional interchangeability within frequency constraints.
Frequently Asked Questions (FAQ)
Q: Can NBC12429FAR2G replace NBC12430FAR2G in all applications?
A: No. The NBC12429FAR2G has a maximum frequency rating of 400MHz compared to 800MHz for the NBC12430FAR2G. Substitution is valid only when the application frequency requirement does not exceed 400MHz. Verify your circuit's frequency specification before substitution.
Q: Are the physical packages identical?
A: Yes. Both parts use the 32-LQFP (7x7) package with identical footprint and pin configuration. PCB layout compatibility is confirmed between these parts.
Q: What is the difference between Cut Tape and Tape & Reel packaging?
A: Cut Tape (CT) is supplied in smaller quantities on individual tape segments, suitable for manual assembly or small production runs. Tape & Reel (TR) is supplied on continuous reels, optimized for automated pick-and-place assembly equipment. Select based on your assembly process requirements.
Q: Are both parts RoHS compliant?
A: Yes. Both NBC12430FAR2G and NBC12429FAR2G are ROHS3 compliant and REACH unaffected, meeting regulatory requirements for restricted substance use.
Q: Can I use NBC12430FAR2G as a substitute for NBC12429FAR2G?
A: Yes. The NBC12430FAR2G is a higher-frequency variant (800MHz) of the NBC12429FAR2G (400MHz). It can be used as a direct substitute in applications designed for the NBC12429FAR2G, as it meets or exceeds all electrical specifications.
Q: What is the supply voltage range for both parts?
A: Both parts operate with a supply voltage range of 3.135V to 5.25V, providing compatibility with standard 3.3V and 5V logic systems.
