TC7117RCPL Equivalent & Substitute Parts

Part Overview

The TC7117RCPL is a 7-segment display driver IC manufactured by Microchip Technology, designed for 4.6-digit display applications in a 40-DIP through-hole package. This component is classified as obsolete, which necessitates identification of equivalent and substitute parts for ongoing design support and production continuity. The part operates at 5V supply voltage with an operating temperature range of 0°C to 70°C and is ROHS3 compliant.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the TC7117RCPL is determined by the following critical parameters:

• Display Driver Functionality: All substitute parts must provide 7-segment display driving capability
• Digit Resolution: The main part supports 4.6-digit display; substitutes must support equivalent or greater digit capacity
• Supply Voltage Compatibility: Primary substitute (TC7117CPL) operates at identical 5V supply; alternative substitutes operate within compatible voltage ranges (4V–6V or 9V single supply)
• Mounting Type: Through-hole mounting is preferred for direct replacement; surface-mount alternatives are listed where functional equivalence exists
• Package Compatibility: 40-DIP through-hole is the primary form factor; alternative packages (28-DIP, 44-QFP) represent functional equivalents with different physical configurations
• Compliance Standards: All substitutes maintain ROHS3 compliance and REACH unaffected status

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: TC7117CPL

The TC7117CPL is the manufacturer-recommended direct replacement for the TC7117RCPL. Both parts share identical electrical specifications (5V supply, 0°C–70°C operating range), functional capability (4.6-digit 7-segment display driving), and physical form factor (40-DIP through-hole). The TC7117CPL is in active production status with higher inventory availability (4615 units), ensuring supply chain continuity. This part is the preferred choice for direct substitution in existing designs.

Secondary Substitutes: ICL7136CMH+TD, ICM7228AIPIZ, ICM7228CIPIZ

These alternatives provide functional equivalence for 7-segment display driving but require design modifications:

• ICL7136CMH+TD: Supports 4.6-digit resolution matching the main part specification. Operates at 9V single supply (not 5V) and uses surface-mount 44-QFP packaging. Suitable for redesigned circuits with different power supply architecture and PCB layout.

• ICM7228AIPIZ and ICM7228CIPIZ: Both support 8-digit 7-segment display driving, exceeding the 4.6-digit requirement. Operate within 4V–6V supply range (compatible with 5V systems). Use 28-DIP through-hole packaging, reducing board footprint compared to 40-DIP. Extended operating temperature range (-40°C–85°C) provides broader environmental capability. Both parts are functionally identical with different temperature grade designations.

All substitute parts maintain ROHS3 compliance and REACH unaffected status, meeting regulatory requirements equivalent to the main part.

Frequently Asked Questions (FAQ)

Q: Can TC7117CPL be used as a direct replacement for TC7117RCPL without circuit modification?

A: Yes. The TC7117CPL is electrically and functionally identical to the TC7117RCPL, with matching 5V supply voltage, 40-DIP through-hole package, and 4.6-digit display driver capability. No circuit redesign is required.

Q: What are the key differences between TC7117CPL and ICL7136CMH+TD?

A: The primary differences are supply voltage (5V vs. 9V), package type (40-DIP through-hole vs. 44-QFP surface-mount), and digit resolution (4.6-digit vs. 4.6-digit). The ICL7136CMH+TD requires circuit redesign for power supply and PCB layout changes.

Q: Why are ICM7228AIPIZ and ICM7228CIPIZ listed as substitutes if they support 8 digits instead of 4.6 digits?

A: The ICM7228 series provides functional equivalence for 7-segment display driving applications. The 8-digit capability exceeds the 4.6-digit requirement, allowing these parts to function in the same application role. The reduced package size (28-DIP vs. 40-DIP) and extended temperature range (-40°C–85°C) offer design advantages in certain applications.

Q: Are there supply voltage compatibility concerns with ICM7228AIPIZ and ICM7228CIPIZ?

A: No. Both ICM7228 variants operate within the 4V–6V supply range, which encompasses the 5V supply voltage of the TC7117RCPL. These parts are compatible with existing 5V power supplies.

Q: What is the difference between ICM7228AIPIZ and ICM7228CIPIZ?

A: Both parts are functionally identical 7-segment display drivers with 8-digit capability. The designation difference reflects temperature grade or manufacturing lot classification. Electrical specifications, package, and performance characteristics are equivalent.

Q: Does moisture sensitivity affect component handling for these substitutes?

A: The TC7117RCPL, TC7117CPL, ICM7228AIPIZ, and ICM7228CIPIZ all have MSL 1 (Unlimited), requiring no special moisture control during storage or handling. The ICL7136CMH+TD has MSL 3 (168 Hours), requiring moisture control measures and baking procedures if storage exceeds 168 hours in standard humidity conditions.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts (TC7117CPL, ICL7136CMH+TD, ICM7228AIPIZ, ICM7228CIPIZ) are ROHS3 compliant and REACH unaffected, meeting regulatory requirements equivalent to the main part.
