Key Parameters

Substitute Part Grouping Explanation

Substitution of the NB2304AI2DR2G is determined by strict equivalence across the following critical parameters:

• Frequency Performance: Maximum frequency of 133.3MHz
• Signal Type: CMOS input and CMOS output
• Distribution Ratio: 1:4 input-to-output configuration
• Supply Voltage: 3V to 3.6V operating range
• Package Format: 8-SOIC (0.154", 3.90mm Width) surface mount
• Temperature Range: -40°C to 85°C operational limits
• Functional Classification: Zero Delay Buffer with integrated PLL

The NB2304AI1DR2G meets all these criteria and is classified as a parametric equivalent. The primary distinction between the main part and its substitute is the packaging format (tape reel versus cut tape), which does not affect electrical or mechanical compatibility in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

Both the NB2304AI2DR2G and NB2304AI1DR2G are classified as obsolete products. Selection between these parts should be based on procurement and assembly requirements rather than electrical performance, as all functional and mechanical parameters are identical.

The NB2304AI1DR2G offers higher current inventory availability (2192 Pcs) compared to the NB2304AI2DR2G (2078 Pcs), which may influence procurement decisions for volume applications. Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for current manufacturing standards.

The packaging format difference (tape reel versus cut tape) affects only the supply chain and assembly process. Circuit-level performance and PCB integration are unaffected by this distinction.

Frequently Asked Questions (FAQ)

Q: Can NB2304AI1DR2G be used as a direct replacement for NB2304AI2DR2G?

A: Yes. All electrical specifications, frequency performance, signal characteristics, supply voltage requirements, and package dimensions are identical. The only difference is the packaging format (cut tape versus tape reel), which does not affect circuit functionality or PCB mounting compatibility.

Q: What does the packaging format difference mean for assembly?

A: NB2304AI2DR2G arrives in tape reel format, suitable for automated pick-and-place assembly systems. NB2304AI1DR2G arrives in cut tape format, typically used for manual assembly or smaller batch operations. Both formats contain the same component with identical electrical properties.

Q: Are there any compliance or certification differences between these parts?

A: No. Both parts maintain identical RoHS3 compliance status and REACH unaffected classification. Regulatory and environmental compliance requirements are fully satisfied by either part.

Q: Why is the NB2304AI2DR2G classified as obsolete?

A: Product status reflects onsemi's manufacturing and support lifecycle decisions. Obsolete classification indicates the part is no longer in active production, making the NB2304AI1DR2G a viable alternative for ongoing applications requiring this functionality.

Q: What are the critical parameters for substitution compatibility?

A: Substitution compatibility is determined by matching frequency (133.3MHz), supply voltage (3V to 3.6V), signal type (CMOS input/output), distribution ratio (1:4), package format (8-SOIC), and temperature range (-40°C to 85°C). All these parameters are identical between the main part and its substitute.
