Key Parameters

Substitute Part Grouping Explanation

Substitution of the PCF2119IU/2DA/2Z is determined by strict equivalence across the following parameters:

• Base product number (PCF2119 series)
• Display type (LCD)
• Display configuration (7 Segment + DP, 14 Segment + DP + AP, Dot Matrix)
• Interface protocol (I2C and Parallel support)
• Display element capacity (16, 32, or 40 elements)
• Supply current specification (35 µA)
• Supply voltage range (1.5V ~ 5.5V)
• Operating temperature range (-40°C ~ 85°C)
• Mounting type (Surface Mount)
• Package form (Die)
• Regulatory compliance (ROHS3, REACH Unaffected)

The primary distinction between the main part and its substitute lies in product status and packaging configuration. The substitute part maintains identical electrical and functional specifications while offering active product status and alternative packaging.

Parameter Comparison

Engineering Selection Recommendations

The PCF2119RU/2/F2Z is the direct active equivalent for the obsolete PCF2119IU/2DA/2Z. Both parts maintain identical electrical specifications, functional capabilities, and regulatory compliance status. The substitute part is currently in active production status with confirmed inventory availability.

Selection of the PCF2119RU/2/F2Z is appropriate for applications requiring:

• LCD driver functionality with 7-segment, 14-segment, or dot matrix display support
• I2C or parallel interface communication
• Supply voltage operation within 1.5V to 5.5V range
• Low-power operation at 35 µA supply current
• Extended temperature operation from -40°C to 85°C
• ROHS3 compliance and REACH regulatory adherence

The packaging difference (tray configuration for the substitute versus die configuration for the original) reflects standard distribution practices and does not affect functional or electrical compatibility.

Frequently Asked Questions (FAQ)

Q: What is the primary reason for substituting PCF2119IU/2DA/2Z?

A: The PCF2119IU/2DA/2Z is classified as obsolete. The PCF2119RU/2/F2Z provides identical electrical and functional specifications while maintaining active product status and current manufacturing availability.

Q: Are the electrical specifications identical between the main part and substitute?

A: Yes. Both parts share identical supply current (35 µA), supply voltage range (1.5V ~ 5.5V), operating temperature range (-40°C ~ 85°C), display configurations, and interface protocols.

Q: What is the difference between the packaging configurations?

A: The original part (PCF2119IU/2DA/2Z) is supplied as a die. The substitute (PCF2119RU/2/F2Z) is supplied in tray packaging. Both are surface mount die packages with identical functional performance.

Q: Are both parts ROHS3 compliant?

A: Yes. Both PCF2119IU/2DA/2Z and PCF2119RU/2/F2Z are ROHS3 compliant and REACH unaffected.

Q: Can PCF2119RU/2/F2Z support the same display configurations as the original part?

A: Yes. The substitute part supports identical display configurations: 7 Segment + DP, 14 Segment + DP + AP, and Dot Matrix, with support for 16, 32, or 40 display elements.

Q: What interface protocols are supported by the substitute part?

A: The PCF2119RU/2/F2Z supports both I2C and parallel interface protocols, identical to the original PCF2119IU/2DA/2Z.
