GMC7175CA Equivalent & Substitute Parts

Part Overview

The GMC7175CA is a 5 x 7 dot matrix display module manufactured by onsemi, featuring a common cathode row and common anode column configuration with red LEDs. This component is classified as obsolete, making equivalent substitute parts necessary for new designs and ongoing production requirements. The module operates at a forward voltage of 2.1V and delivers 3mcd brightness, housed in a compact 0.50" L x 0.70" W x 0.25" H form factor.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the GMC7175CA is determined by the following critical parameters:

• Configuration: Must be 5 x 7 dot matrix
• Internal Connection: Must be common cathode row, common anode column
• Color: Must be red
• Size / Dimension: Must be 0.50" L x 0.70" W x 0.25" H (12.70mm x 17.80mm x 6.30mm)
• Voltage - Forward (Vf): Acceptable range 2.0V to 2.1V
• Moisture Sensitivity Level: Must be MSL 1 (Unlimited)

The TA07-11EWA from Kingbright meets all substitution criteria, maintaining identical mechanical dimensions, configuration, and connection topology while operating within the acceptable forward voltage range.

Parameter Comparison

Engineering Selection Recommendations

The TA07-11EWA serves as a direct substitute for the GMC7175CA based on matching mechanical dimensions, identical pin configuration, and compatible electrical parameters. The TA07-11EWA is currently in active production status, ensuring long-term availability and supply chain continuity. The substitute part is RoHS3 compliant and carries REACH Unaffected status, meeting current regulatory requirements. The forward voltage differential of 0.1V falls within acceptable tolerance for standard display driver circuits. The increased brightness rating of the TA07-11EWA (8.2mcd versus 3mcd) provides enhanced visibility without requiring circuit modifications.

Frequently Asked Questions (FAQ)

Q: Can the TA07-11EWA replace the GMC7175CA in existing designs?

A: Yes. Both parts share identical mechanical dimensions (0.50" L x 0.70" W x 0.25" H), the same 5 x 7 configuration, and matching common cathode row / common anode column internal connections. The forward voltage difference of 0.1V is within standard operating tolerances for display driver circuits.

Q: What is the significance of the higher millicandela rating on the TA07-11EWA?

A: The TA07-11EWA delivers 8.2mcd compared to the GMC7175CA's 3mcd. This increased brightness is a performance enhancement that does not affect electrical compatibility or circuit operation.

Q: Are there packaging differences between these parts?

A: Both parts are supplied in tube packaging, maintaining consistent handling and storage requirements.

Q: Why is the GMC7175CA classified as obsolete?

A: The GMC7175CA is no longer in active production. The TA07-11EWA is the recommended active alternative for new designs and production continuity.

Q: Do both parts meet current compliance standards?

A: The TA07-11EWA is RoHS3 compliant and REACH Unaffected. Both parts carry MSL 1 (Unlimited) moisture sensitivity ratings and EAR99 ECCN classification.
