COM-11440 Equivalent & Substitute Parts Reference

Part Overview

The COM-11440 is a 4-digit addressable LED 7-segment display module with I2C, SPI, and UART interface capabilities, featuring green LEDs and an ATMega328 controller. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system design and maintenance applications. The module's compact form factor (40.60mm L × 22.90mm W) and multi-protocol interface support make it suitable for digital display applications requiring addressable control.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the COM-11440 is determined by strict alignment with the following critical parameters:

• Configuration & Display Type: 7-segment, 4-digit format
• Controller Architecture: ATMega328 microcontroller
• Interface Protocols: I2C, SPI, and UART support
• Physical Dimensions: 40.60mm L × 22.90mm W
• Mounting Compatibility: User-defined mounting type
• Environmental Compliance: RoHS compliance and MSL rating

The COM-11629 qualifies as a substitute based on identical configuration, controller type, interface protocols, physical dimensions, and mounting specifications. The primary distinction is LED color (white vs. green) and product status (active vs. obsolete), which do not affect functional substitutability in applications where display color is not a critical design constraint.

Parameter Comparison

Engineering Selection Recommendations

The COM-11629 is the designated substitute for the obsolete COM-11440 based on functional equivalence across all critical electrical and mechanical parameters. Both components share identical configuration, controller architecture, interface protocol support, and physical dimensions, ensuring direct compatibility in existing designs.

The COM-11629 offers the additional advantage of active product status, ensuring continued availability and supply chain reliability. Both parts maintain equivalent environmental compliance certifications (RoHS and MSL 1), supporting deployment in standard industrial and commercial applications.

Selection between these parts should be based solely on LED color requirements: green for COM-11440 applications or white for COM-11629 applications. No functional or electrical modifications are required when transitioning between these parts.

Frequently Asked Questions (FAQ)

Q: Can COM-11629 directly replace COM-11440 in existing designs?

A: Yes. Both parts share identical configuration (7-segment, 4-digit), controller type (ATMega328), interface protocols (I2C, SPI, UART), physical dimensions (40.60mm L × 22.90mm W), and mounting specifications. Direct substitution is supported without circuit or firmware modifications.

Q: What is the primary difference between COM-11440 and COM-11629?

A: The primary difference is LED color: COM-11440 features green LEDs, while COM-11629 features white LEDs. COM-11629 also maintains active product status, whereas COM-11440 is obsolete.

Q: Are there any compatibility concerns with the packaging difference?

A: COM-11440 is listed with standard packaging, while COM-11629 is supplied in bulk packaging. This distinction affects only procurement and handling procedures, not functional compatibility or electrical performance.

Q: Do both parts meet the same environmental compliance standards?

A: Both parts are RoHS compliant and maintain MSL 1 (Unlimited) moisture sensitivity ratings. COM-11629 specifically carries ROHS3 certification, representing an updated compliance standard. Both are suitable for equivalent environmental applications.

Q: Which part should be selected for new designs?

A: COM-11629 is the appropriate choice for new designs due to its active product status and continued availability. COM-11440 should be reserved for legacy system maintenance only.
