TC7136CPL Equivalent & Substitute Parts

Part Overview

The TC7136CPL is a 4.6-digit display driver IC manufactured by Microchip Technology in a 40-DIP package. This component is classified as obsolete, making equivalent and substitute parts necessary for new designs and ongoing production support. The TC7136CPL operates on a 9V supply and supports through-hole mounting with an operating temperature range of 0°C to 70°C. Substitute parts maintain functional compatibility through matching electrical specifications and package form factors while offering active product status and improved compliance certifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TC7136CPL are qualified based on the following critical parameters:

• Package compatibility: 40-DIP (0.600", 15.24mm) form factor
• Mounting type: Through-hole configuration
• Voltage supply: 9V operation
• Operating temperature range: 0°C ~ 70°C
• Resolution: 4.6-digit display driver functionality
• Mounting interface: PDIP supplier device package

Substitute parts are grouped into two categories based on manufacturer source and channel configuration. All substitute parts maintain the 40-DIP package specification and support the required 9V supply voltage. Parts designated with the "Z" suffix (ICL7106CPLZ, ICL7126CPLZ, ICL7136CPLZ) feature dual-channel configurations from Renesas Electronics Corporation. Parts with the "+" suffix (ICL7106CPL+, ICL7126CPL+, ICL7136CPL+) are single-channel variants from Analog Devices Inc./Maxim Integrated.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed maintain active product status, providing long-term availability and supply chain stability compared to the obsolete TC7136CPL. All substitute parts achieve ROHS3 compliance, meeting current environmental and regulatory requirements.

For applications requiring 9V supply operation, ICL7106CPL+, ICL7126CPL+, ICL7126CPLZ, ICL7136CPL+, and ICL7136CPLZ are direct electrical equivalents. The ICL7106CPLZ operates at 5V supply voltage and is suitable only for designs with 5V power architecture.

Single-channel configurations (ICL7106CPL+, ICL7126CPL+, ICL7136CPL+) provide functional equivalence for applications requiring one display driver channel. Dual-channel configurations (ICL7106CPLZ, ICL7126CPLZ, ICL7136CPLZ) support multi-display applications within a single package footprint.

The ICL7136 series variants (ICL7136CPL+ and ICL7136CPLZ) represent the closest functional equivalents to the TC7136CPL, maintaining identical base product specifications and supply voltage requirements.

Frequently Asked Questions (FAQ)

Q: Can ICL7106CPLZ be used as a direct replacement for TC7136CPL?

A: ICL7106CPLZ is mechanically compatible through the 40-DIP package form factor and supports through-hole mounting. However, it operates at 5V supply voltage, whereas TC7136CPL requires 9V. This part is suitable only for designs with 5V power architecture.

Q: What is the difference between single-channel (+) and dual-channel (Z) variants?

A: Single-channel variants (ICL7106CPL+, ICL7126CPL+, ICL7136CPL+) provide one display driver channel per package. Dual-channel variants (ICL7106CPLZ, ICL7126CPLZ, ICL7136CPLZ) provide two display driver channels within the same 40-DIP package footprint. Channel count does not affect package dimensions or mounting compatibility.

Q: Are all substitute parts RoHS compliant?

A: All substitute parts listed are ROHS3 compliant. The original TC7136CPL is RoHS non-compliant. Compliance certification is a key differentiator for new designs and applications subject to environmental regulations.

Q: Which substitute part offers the best inventory availability?

A: ICL7106CPLZ from Renesas Electronics Corporation has the highest inventory level at 19,833 pieces. ICL7136CPLZ follows with 2,200 pieces. Inventory levels are subject to change and should be verified with suppliers.

Q: Can substitute parts be used interchangeably in existing TC7136CPL designs?

A: Substitute parts maintain identical package form factors, mounting types, and operating temperature ranges. Electrical compatibility depends on supply voltage requirements. Parts operating at 9V (ICL7106CPL+, ICL7126CPL+, ICL7126CPLZ, ICL7136CPL+, ICL7136CPLZ) are electrically compatible with TC7136CPL designs. Channel configuration differences do not affect pin-to-pin compatibility for single-channel applications.

Q: What is the significance of the base product number (ICL7106, ICL7126, ICL7136)?

A: The base product number identifies the core functional variant. ICL7106 and ICL7136 are display driver variants. ICL7126 is an ADC variant with display driver functionality. All three base products support 4.6-digit resolution and 40-DIP packaging. Selection between base product numbers depends on specific application requirements beyond display driving functionality.
