DLP4500FQD Digital Micromirror Device Equivalent & Substitute Parts

Part Overview

The DLP4500FQD is a Digital Micromirror Device (DMD) manufactured by Texas Instruments in a 98-LCCC surface mount package. This component is classified as obsolete, making identification of suitable substitute parts essential for ongoing system support and new design implementations. The DLP4500FQD serves applications in 3D projection and medical imaging systems where precise micromirror array control is required. Due to its obsolete status, sourcing alternatives from the active product line is necessary for procurement continuity.

Substitute Part Grouping Explanation

Substitution of the DLP4500FQD is determined by strict alignment of the following parameters:

Critical Substitution Criteria:

• Identical base product number (DLP4500)
• Identical package type (98-CLCC / 98-LCCC 20.7x9.1)
• Identical mounting type (Surface Mount)
• Compatible application scope (3D, Medical Imaging)
• Matching RoHS and REACH compliance status
• Equivalent or superior product status

The DLP4500AFQD meets all substitution criteria as a direct equivalent within the DLP4500 product family. Both components share identical mechanical and electrical specifications, with the primary distinction being product lifecycle status.

Parameter Comparison

Engineering Selection Recommendations

DLP4500AFQD is the direct substitute for DLP4500FQD based on the following engineering criteria:

1. Product Status Alignment: The DLP4500AFQD maintains active product status with Texas Instruments, ensuring long-term availability and manufacturing support. The DLP4500FQD is obsolete, creating supply chain risk.

2. Compliance Certification: Both components maintain identical ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for new designs and legacy system support.

3. Package and Mechanical Compatibility: Identical 98-LCCC surface mount package specifications (20.7x9.1 mm) ensure direct PCB layout compatibility without redesign requirements.

4. Application Scope: Both components support identical application domains (3D projection and medical imaging), confirming functional equivalence for system-level requirements.

5. Supply Chain Continuity: The DLP4500AFQD is available in significantly higher inventory (3200 pcs) compared to the obsolete DLP4500FQD (940 pcs), providing procurement reliability.
