Substitute Part Grouping Explanation

Substitution of the DS5002FPM-16 is determined by strict equivalence across the following critical parameters:

• Core Architecture: 8051 processor family
• Operating Frequency: 16MHz
• Memory Configuration: External NVSRAM program memory with 128K x 8 RAM
• Electrical Specifications: 4.5V to 5.5V supply voltage range
• I/O Count: 32 I/O pins
• Interface Standards: EBI/EMI, SIO, UART/USART connectivity
• Integrated Peripherals: Power-Fail Reset and Watchdog Timer
• Package Format: 80-MQFP (14x20) surface mount

The DS5002FPM-16+ maintains complete electrical and functional equivalence to the DS5002FPM-16 across all specified parameters, differing only in product status and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The DS5002FPM-16+ is the direct active equivalent of the DS5002FPM-16. Selection between these parts is determined by regulatory and compliance requirements:

DS5002FPM-16+ is the preferred choice for new designs and production applications due to its active product status and ROHS3 compliance certification. This part satisfies modern regulatory requirements and ensures long-term supply availability.

DS5002FPM-16 remains suitable for legacy system maintenance and repair applications where RoHS non-compliance does not present a constraint. This part is classified as obsolete and should not be selected for new designs.

Both parts are electrically and functionally identical across all specified parameters. The primary differentiator is product lifecycle status and environmental compliance certification. Moisture sensitivity level differences (MSL 3 versus MSL 4) reflect manufacturing process updates and do not affect functional equivalence.

Frequently Asked Questions (FAQ)

Q: Are DS5002FPM-16 and DS5002FPM-16+ pin-for-pin compatible?

A: Yes. Both parts use the 80-MQFP (14x20) package with identical pinout, I/O count (32), and electrical specifications. Direct substitution is possible without PCB redesign.

Q: What is the functional difference between these parts?

A: There is no functional difference. Both parts implement the 8051 core processor at 16MHz with external NVSRAM program memory and 128K x 8 RAM. All connectivity interfaces, peripherals, and electrical parameters are identical.

Q: Why does the DS5002FPM-16+ have a different MSL rating?

A: The MSL 4 (72 Hours) rating for DS5002FPM-16+ reflects updated manufacturing processes. This does not affect functional performance or electrical characteristics. MSL ratings determine moisture exposure limits during storage and handling; both parts require appropriate moisture control during assembly.

Q: Can DS5002FPM-16+ be used as a direct replacement in existing designs?

A: Yes. The DS5002FPM-16+ is a direct functional and electrical equivalent. No design modifications are required for substitution. The primary advantage is active product status and ROHS3 compliance.

Q: What is the supply status difference between these parts?

A: DS5002FPM-16 is classified as obsolete with limited availability. DS5002FPM-16+ is active and maintains ongoing production and distribution. For new applications, DS5002FPM-16+ ensures supply chain continuity.
