2. Market Trends & Insights (2026)

The market for the DAC7631E series is currently in a "Maintenance & Transition" phase.

• Lifecycle Status: ACTIVE, but considered a legacy component Ti. Texas Instruments recommends DAC80501 for new designs as it offers integrated references and a smaller WSON package Ti.
• Inventory & Lead Times:
• Stock Levels: Major distributors like Mouser and DigiKey maintain low on-hand stock (typically <50 units), indicating it is primarily sourced for maintenance DigikeyMouser.
• Lead Times: Standard manufacturer lead times are currently 12 to 18 weeks MouserDigikey.
• Pricing Trends:
• Wholesale/Distribution: Prices range from $10.37 to $12.44 for 1k units Ti.
• Retail/Immediate Stock: Unit prices can spike to $50+ on secondary markets for immediate delivery of original 2026 date-code parts Alibaba.
• Market Dynamics: The broader data converter market is projected to reach $6.3 billion in 2026, driven by a 7.08% CAGR in high-speed, high-precision applications DatainsightsreportsMordorintelligence.

3. Buying Advice

• For New Projects: Avoid designing with DAC7631E; opt for modern alternatives like the DAC80501 to ensure long-term availability and lower component costs.
• For Maintenance: Secure inventory early due to the 4-month lead time. Verified B2B suppliers in hubs like Shenzhen currently show active orders for this part Alibaba.
