Key Parameters

Substitute Part Grouping Explanation

Substitution for the TC7126RCPL is determined by strict alignment of the following critical parameters:

• Package Format: 40-DIP (0.600", 15.24mm) — physical and electrical pin compatibility
• Voltage Supply: 9V single supply operation
• Operating Temperature Range: 0°C ~ 70°C
• Mounting Type: Through Hole configuration
• Functional Classification: Display Driver for 4.6-digit applications
• Compliance Standards: ROHS3 Compliant, REACH Unaffected, EAR99 classification

The ICL7126CPL+ from Analog Devices Inc./Maxim Integrated meets all these criteria and is classified as an active product, making it a direct functional equivalent for the obsolete TC7126RCPL.

Engineering Selection Recommendations

The ICL7126CPL+ is the primary substitute for the obsolete TC7126RCPL. Selection is based on the following engineering criteria:

• Product Status Alignment: The ICL7126CPL+ maintains active production status, ensuring long-term availability and supply chain continuity compared to the obsolete TC7126RCPL.
• Electrical Compatibility: Identical voltage supply (9V), operating temperature range (0°C ~ 70°C), and functional resolution (4.6-digit display driver) ensure direct functional replacement.
• Physical Compatibility: Both parts utilize the 40-DIP package format with identical pin spacing (0.600", 15.24mm), enabling direct PCB footprint compatibility without layout modifications.
• Regulatory Compliance: Both parts maintain ROHS3 compliance, REACH unaffected status, and EAR99 export classification, ensuring regulatory requirements are met across manufacturing and distribution.
• Moisture Handling: Both parts carry MSL Level 1 (Unlimited), indicating no moisture sensitivity constraints during storage or handling.

Frequently Asked Questions (FAQ)

Q: Can the ICL7126CPL+ be used as a direct replacement for TC7126RCPL in existing designs?

A: Yes. The ICL7126CPL+ is electrically and physically compatible with the TC7126RCPL. Both parts share identical package format (40-DIP), voltage supply (9V), operating temperature range (0°C ~ 70°C), and functional resolution (4.6-digit display driver). No PCB modifications or design changes are required.

Q: What is the primary reason for substitution?

A: The TC7126RCPL is classified as obsolete, meaning Microchip Technology has discontinued production. The ICL7126CPL+ is an active product from Analog Devices Inc./Maxim Integrated, ensuring continued availability and supply chain reliability.

Q: Are there any compliance or certification differences between these parts?

A: No. Both parts maintain identical compliance status: ROHS3 compliant, REACH unaffected, and EAR99 export classification. Moisture sensitivity levels are also identical (MSL Level 1 - Unlimited).

Q: What package format do these parts use?

A: Both the TC7126RCPL and ICL7126CPL+ use the 40-DIP package with 0.600" (15.24mm) pin spacing. This is a through-hole mounting configuration suitable for standard PCB assembly processes.

Q: Are there any supply voltage or temperature range differences?

A: No. Both parts operate on a single 9V supply and function across the identical temperature range of 0°C to 70°C, ensuring seamless substitution in existing applications.
