Substitute Part Grouping Explanation

Substitution of the PCF8576CU/2/F2,026 is determined by strict alignment of the following electrical and mechanical parameters:

Critical Substitution Criteria:

• Identical base product number (PCF8576 series)
• Matching display configuration support (7 Segment + DP, 14 Segment + DP + AP, Dot Matrix)
• Identical I2C interface protocol
• Compatible character/element capacity (10, 20 characters or 160 elements)
• Overlapping supply voltage range
• Identical operating temperature range (-40°C ~ 85°C)
• Same mounting type (Surface Mount) and package form (Die)
• Equivalent RoHS and REACH compliance status

The PCF8576DU/2DA/2,02 meets all substitution criteria as an active product variant within the same PCF8576 family, offering improved power efficiency and expanded voltage compatibility.

Engineering Selection Recommendations

The PCF8576DU/2DA/2,02 is the qualified substitute for the obsolete PCF8576CU/2/F2,026. Selection is based on the following engineering factors:

Product Status: The substitute part maintains active production status with NXP USA Inc., ensuring long-term availability and supply chain continuity compared to the obsolete main part.

Compliance Certification: Both parts maintain identical ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for new designs and manufacturing environments.

Electrical Compatibility: The substitute operates within the main part's supply voltage range (1.8V ~ 5.5V encompasses the original 2V ~ 6V specification) and maintains identical operating temperature specifications (-40°C ~ 85°C). The reduced supply current (8 µA versus 120 µA) represents an improvement in power efficiency without functional compromise.

Functional Equivalence: Both parts support identical display configurations, character capacities, and I2C interface protocols, ensuring direct functional substitution in existing circuit designs.

Frequently Asked Questions (FAQ)

Q: Can the PCF8576DU/2DA/2,02 directly replace the PCF8576CU/2/F2,026 in existing designs?

A: Yes. Both parts share identical display configuration support, I2C interface protocol, character/element capacity, operating temperature range, and package form. The substitute operates within the original part's supply voltage specification and maintains equivalent compliance certifications.

Q: What are the key differences between these two parts?

A: The primary differences are product status (obsolete versus active), supply voltage range (2V ~ 6V versus 1.8V ~ 5.5V), and supply current (120 µA versus 8 µA). The substitute offers improved power efficiency and slightly expanded lower voltage operation while maintaining all functional specifications.

Q: Are there packaging differences between the main part and substitute?

A: Both parts are supplied as dies in surface mount configuration. The main part uses die packaging, and the substitute is supplied in tray packaging. The die form factor remains identical for both parts.

Q: Does the lower supply current of the substitute affect circuit design?

A: No. The reduced supply current (8 µA) of the PCF8576DU/2DA/2,02 represents improved efficiency and does not require circuit modifications. Existing designs will function identically with reduced power consumption.

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both the PCF8576CU/2/F2,026 and PCF8576DU/2DA/2,02 maintain ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for electronic component manufacturing and distribution.
