Key Parameters

Substitute Part Grouping Explanation

Substitution of the MC1408PC is determined by the following core electrical and mechanical parameters:

• Resolution: 8-bit digital-to-analog conversion capability
• Architecture: Multiplying DAC topology
• Output Configuration: Current output, unbuffered
• Data Interface: Parallel digital input
• Reference Type: External reference requirement
• Supply Voltage Range: ±4.5V to ±18V analog supply compatibility
• Package Type: Surface mount or through-hole equivalent with compatible pinout
• Compliance: ROHS3 compliance and REACH unaffected status
• Regulatory Classification: EAR99 export control classification

The DAC0808LCM/NOPB meets all substitution criteria as a direct functional equivalent with active product status and verified compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The DAC0808LCM/NOPB is the designated manufacturer-recommended substitute for the obsolete MC1408PC. Both components share identical electrical specifications for 8-bit multiplying DAC functionality, external reference configuration, and unbuffered current output operation. The substitute maintains full compliance with ROHS3 requirements and REACH regulations, with equivalent moisture sensitivity classification and export control status.

The primary distinction is product lifecycle status: the MC1408PC has reached end-of-life, while the DAC0808LCM/NOPB maintains active manufacturing and distribution status. The substitute offers documented settling time performance of 150 nanoseconds typical, providing measurable performance data for system design validation.

Frequently Asked Questions (FAQ)

Q: Can the DAC0808LCM/NOPB directly replace the MC1408PC in existing designs?

A: Yes. Both components implement 8-bit multiplying DAC architecture with identical electrical parameters: external reference requirement, ±4.5V to ±18V analog supply range, parallel digital interface, and unbuffered current output. Pinout compatibility and functional equivalence are established.

Q: What is the primary reason for substitution?

A: The MC1408PC has reached obsolete product status. The DAC0808LCM/NOPB is the active equivalent maintained by Texas Instruments for continued system support and new production requirements.

Q: Are there compliance or regulatory differences between these parts?

A: No. Both components carry identical ROHS3 compliance, REACH unaffected status, EAR99 export classification, and moisture sensitivity level 1 rating. Regulatory and environmental compliance requirements are fully maintained.

Q: What packaging differences exist?

A: The MC1408PC packaging specification is not provided in available data. The DAC0808LCM/NOPB is supplied in 16-SOIC surface mount package (0.154" width, 3.90mm). Verify original MC1408PC package type against application requirements before implementation.

Q: Is settling time performance a critical factor for substitution?

A: The DAC0808LCM/NOPB specifies 150 nanoseconds typical settling time. Original MC1408PC settling time data is not provided. For applications with strict timing requirements, confirm that 150ns settling time meets system specifications.
