Substitute Part Grouping Explanation

Substitution eligibility for the COM-11648 is determined by the following critical parameters:

• Configuration & Display Type: 7-segment format with 4-digit display capacity
• LED Color: White LEDs only
• Controller Architecture: ATMega328 microcontroller
• Communication Interfaces: I2C, SPI, and UART support
• Physical Dimensions: 40.60mm L × 22.90mm W form factor
• Compliance Standards: RoHS compliance and MSL rating

The COM-11629 qualifies as a direct substitute based on matching all critical electrical and mechanical parameters while offering improved product status and compliance certification.

Parameter Comparison

Engineering Selection Recommendations

The COM-11629 is the qualified substitute for COM-11648. Both parts maintain identical electrical specifications, interface capabilities, and physical form factors. The primary distinction is product lifecycle status: COM-11648 is obsolete while COM-11629 remains in active production. Additionally, COM-11629 carries ROHS3 compliance certification, representing an updated compliance standard relative to the RoHS Compliant designation of the original part. For new designs or production continuity, COM-11629 is the appropriate selection.

Frequently Asked Questions (FAQ)

Q: Can COM-11629 be used as a direct replacement for COM-11648?

A: Yes. Both parts share identical configuration (7-segment, 4-digit), LED color (white), controller type (ATMega328), communication interfaces (I2C, SPI, UART), and physical dimensions (40.60mm L × 22.90mm W). Electrical and mechanical compatibility is complete.

Q: What is the difference between RoHS Compliant and ROHS3 Compliant?

A: ROHS3 represents the current iteration of the RoHS directive with updated substance restrictions. COM-11629 meets the latest compliance standard, while COM-11648 meets the earlier RoHS standard. Both are compliant with their respective regulatory frameworks.

Q: Why is COM-11648 listed as obsolete?

A: Product obsolescence typically reflects end-of-life status in the manufacturer's product line. COM-11629 is the active production equivalent and is recommended for all new applications.

Q: Are there any packaging differences between these parts?

A: COM-11648 packaging is not specified in available documentation. COM-11629 is supplied in bulk packaging. Confirm packaging requirements with your procurement department.

Q: Do both parts support the same communication protocols?

A: Yes. Both COM-11648 and COM-11629 support I2C, SPI, and UART interfaces without modification. Protocol selection and implementation remain identical between the two parts.
