ICL7137CPL Display Driver 4.6 Digit 40-DIP Equivalent & Substitute Parts

Part Overview

The ICL7137CPL is a display driver IC designed for 4.6 digit applications in a 40-pin DIP package. This component is classified as obsolete, which necessitates identification of active equivalent parts for new designs and ongoing production requirements. The ICL7137CPL+ serves as the direct active substitute, maintaining identical electrical and mechanical specifications while offering improved compliance status.

Key Parameters

Substitute Part Grouping Explanation

The ICL7137CPL+ qualifies as a direct substitute based on the following critical parameters:

• Identical Resolution: Both parts support 4.6 digit display capability
• Identical Package: 40-DIP (0.600", 15.24mm) ensures mechanical and electrical pin compatibility
• Identical Channel Configuration: Single channel architecture maintained
• Identical Operating Temperature Range: 0°C ~ 70°C operational envelope
• Identical Moisture Sensitivity Level: MSL 1 (Unlimited) classification
• Same Base Product Number: ICL7137 series designation
• Identical Mounting Type: Through hole configuration for PCB assembly compatibility

The primary distinction is product status: ICL7137CPL is obsolete, while ICL7137CPL+ is active production. Additionally, ICL7137CPL+ achieves ROHS3 compliance, whereas the original ICL7137CPL is RoHS non-compliant.

Parameter Comparison

Engineering Selection Recommendations

The ICL7137CPL+ is the appropriate selection for new designs and production applications. This part maintains full electrical and mechanical compatibility with the obsolete ICL7137CPL while offering active product status and ROHS3 compliance. For applications requiring RoHS non-compliant components, the original ICL7137CPL remains available in inventory (2158 pcs), though long-term availability cannot be assured due to obsolete status. The ICL7137CPL+ is actively manufactured and stocked (2000 pcs), providing supply chain continuity and regulatory compliance for modern manufacturing environments.

Frequently Asked Questions (FAQ)

Q: Can ICL7137CPL+ be used as a direct replacement for ICL7137CPL?

A: Yes. Both parts share identical resolution (4.6 digit), package (40-DIP), channel configuration (1), operating temperature range (0°C ~ 70°C), and moisture sensitivity level (MSL 1). Pin-for-pin compatibility is maintained.

Q: What is the primary difference between ICL7137CPL and ICL7137CPL+?

A: The ICL7137CPL+ is the active production equivalent. The original ICL7137CPL is classified as obsolete. Additionally, ICL7137CPL+ achieves ROHS3 compliance, while ICL7137CPL is RoHS non-compliant.

Q: Are there any package or mounting differences?

A: No. Both parts use identical 40-DIP (0.600", 15.24mm) packaging with through-hole mounting. PCB layout and assembly processes require no modification.

Q: What supply chain considerations apply?

A: ICL7137CPL is obsolete with limited remaining inventory (2158 pcs). ICL7137CPL+ is actively manufactured with current inventory (2000 pcs) and represents the recommended selection for ongoing production.

Q: Does substitution require design verification?

A: No design changes are required. Electrical and mechanical parameters are identical. Direct substitution is supported at the component level.
