ICL7126CPL Equivalent & Substitute Parts

Part Overview

The ICL7126CPL is a 4.6-digit display driver integrated circuit manufactured by Analog Devices Inc./Maxim Integrated, housed in a 40-pin DIP package. This component is classified as obsolete, with 4,935 units currently in stock. The ICL7126CPL operates on a single 9V supply and supports through-hole mounting, making it suitable for legacy display applications requiring 4.6-digit numeric output.

Due to the obsolete status of the ICL7126CPL, identifying equivalent and substitute parts is essential for design continuity, system maintenance, and procurement planning. Active alternatives are available from multiple manufacturers with compatible electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ICL7126CPL is determined by the following critical parameters:

• Package Type: All substitutes must use 40-DIP (0.600", 15.24mm) through-hole packaging for direct PCB compatibility
• Voltage Supply: All substitutes must operate on 9V single supply
• Resolution: All substitutes must support 4.6-digit display capability
• Mounting Type: All substitutes must support through-hole mounting
• Moisture Sensitivity Level: All substitutes must maintain MSL 1 (Unlimited) rating

The identified substitute parts meet these core electrical and mechanical requirements. Variations in manufacturer, product status, RoHS compliance, and operating temperature ranges are secondary considerations that do not affect functional substitutability within the specified parameter constraints.

Parameter Comparison

Engineering Selection Recommendations

All identified substitute parts satisfy the core electrical and mechanical requirements for direct substitution with the ICL7126CPL. Selection among these alternatives should be based on the following factors:

Product Status: ICL7126CPL+ (Analog Devices Inc./Maxim Integrated), ICL7126CPLZ (Renesas Electronics Corporation), TC7126ACPL, TC7126CPL, and TC7126IPL (Microchip Technology) are all active products with ongoing manufacturer support and availability.

RoHS Compliance: All substitute parts except the original ICL7126CPL are ROHS3 compliant. For applications requiring RoHS compliance, any of the five substitute parts are suitable. The original ICL7126CPL is RoHS non-compliant.

Operating Temperature Range: TC7126IPL offers an extended operating temperature range of -25°C ~ 85°C, compared to the standard 0°C ~ 70°C range of the ICL7126CPL and other substitutes. Selection of TC7126IPL is appropriate for applications requiring operation outside the standard temperature range.

Manufacturer Continuity: ICL7126CPL+ maintains the original Analog Devices Inc./Maxim Integrated manufacturer lineage and is the closest functional equivalent. TC7126 variants from Microchip Technology represent alternative manufacturer sources with established product status.

Frequently Asked Questions (FAQ)

Q: Can ICL7126CPL+ be used as a direct replacement for ICL7126CPL?

A: Yes. ICL7126CPL+ shares identical electrical specifications (9V supply, 4.6-digit resolution, single channel) and mechanical packaging (40-DIP through-hole). The primary differences are product status (active vs. obsolete) and RoHS compliance (ROHS3 vs. non-compliant).

Q: What is the difference between TC7126ACPL, TC7126CPL, and TC7126IPL?

A: All three are Microchip Technology display drivers with 4.6-digit resolution and 40-DIP packaging. TC7126IPL operates across an extended temperature range (-25°C ~ 85°C) compared to the standard 0°C ~ 70°C range of TC7126ACPL and TC7126CPL. All three are ROHS3 compliant and active products.

Q: Is ICL7126CPLZ compatible with the original ICL7126CPL?

A: Yes. ICL7126CPLZ (Renesas Electronics Corporation) meets all core substitution criteria: 9V supply, 4.6-digit resolution, 40-DIP through-hole package, and MSL 1 rating. It is an active product with ROHS3 compliance.

Q: Does the 40-DIP package ensure pin-for-pin compatibility?

A: The 40-DIP package specification (0.600", 15.24mm) ensures mechanical and electrical interface compatibility for through-hole mounting. All substitute parts use this identical package type, supporting direct PCB socket replacement.

Q: Which substitute part has the best availability?

A: TC7126CPL (Microchip Technology) has the highest current inventory at 2,064 units in stock, followed by ICL7126CPLZ (Renesas) at 1,172 units and TC7126ACPL (Microchip) at 1,206 units.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All five substitute parts (ICL7126CPL+, ICL7126CPLZ, TC7126ACPL, TC7126CPL, TC7126IPL) are ROHS3 compliant. The original ICL7126CPL is RoHS non-compliant.
