Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the COG-T430T6566-04 is determined by strict equivalence across the following critical parameters:

• Display Specifications: Diagonal screen size of 4.3" (109.22mm), pixel resolution of 480 x 272, and transmissive TFT color display type
• Interface Compatibility: Parallel 24-bit RGB interface for direct signal compatibility
• Physical Dimensions: Viewing area of 95.04mm W x 53.86mm H and dot pitch of 0.20mm W x 0.20mm H
• Backlight Configuration: LED white backlight
• Environmental Compliance: RoHS compliance status and MSL rating of 1

The substitute part TCG043WQLBAANN-GN50 meets all these criteria, enabling direct functional replacement in applications originally designed for the COG-T430T6566-04.

Parameter Comparison

Engineering Selection Recommendations

The TCG043WQLBAANN-GN50 from Kyocera International, Inc. is the qualified substitute for the obsolete COG-T430T6566-04. Selection is based on the following engineering criteria:

• Functional Equivalence: All critical display parameters—resolution, interface type, screen size, and backlight configuration—are identical between the main part and substitute
• Compliance Status: Both parts meet RoHS requirements. The substitute carries ROHS3 compliance, which exceeds the original RoHS compliance specification
• Product Availability: The substitute part is currently active in production with confirmed inventory, ensuring long-term supply continuity
• Environmental Rating: Both parts share MSL 1 (Unlimited) moisture sensitivity classification, indicating equivalent handling and storage requirements

The substitute part is suitable for direct replacement in applications where the COG-T430T6566-04 is no longer available.

Frequently Asked Questions (FAQ)

Q: Can the TCG043WQLBAANN-GN50 be used as a direct replacement for the COG-T430T6566-04?

A: Yes. Both parts share identical display specifications (4.3" transmissive TFT, 480 x 272 resolution), interface configuration (parallel 24-bit RGB), and physical dimensions (95.04mm W x 53.86mm H viewing area). No design modifications are required for substitution.

Q: What are the key parameters that determine substitution compatibility?

A: Substitution is determined by equivalence in display type, screen size, pixel resolution, interface type, backlight configuration, viewing area dimensions, and dot pitch. All these parameters are identical between the main part and substitute.

Q: Are there any compliance differences between the two parts?

A: Both parts are RoHS compliant. The substitute carries ROHS3 compliance, which represents an updated standard. Both parts share the same MSL rating of 1 (Unlimited), indicating equivalent environmental handling requirements.

Q: What is the packaging difference?

A: The COG-T430T6566-04 is packaged with standard packaging, while the TCG043WQLBAANN-GN50 is supplied in bulk packaging. Packaging format does not affect functional compatibility.

Q: Why is the original part listed as obsolete?

A: The COG-T430T6566-04 has been discontinued by Varitronix. The TCG043WQLBAANN-GN50 remains in active production, providing a viable long-term alternative for system maintenance and component replacement.
