Substitute parts for the N74F260D,602 are qualified based on the following criteria:

Electrical Parameters (Must Match):

• Logic Type: NOR Gate
• Number of Circuits: 2
• Number of Inputs: 5
• Voltage - Supply: 4.5V ~ 5.5V
• Current - Output High, Low: 1mA, 20mA
• Input Logic Level - Low: 0.8V
• Input Logic Level - High: 2V
• Max Propagation Delay @ V, Max CL: 5.5ns @ 5V, 50pF
• Operating Temperature: 0°C ~ 70°C

Mechanical Parameters (Must Match):

• Mounting Type: Surface Mount
• Package / Case: 14-SOIC (0.154", 3.90mm Width)

Compliance Parameters (Must Match):

Parameter Comparison

Engineering Selection Recommendations

SN74F260DR (Texas Instruments) is the primary substitute for the N74F260D,602. This part carries Active product status, ensuring long-term availability and supply chain stability. It is supplied in Tape & Reel format, suitable for automated assembly processes. All electrical, mechanical, and compliance parameters are equivalent to the original part.

SN74F260D (Texas Instruments) is a secondary substitute with Last Time Buy status. This part is supplied in Tube packaging and includes a specified quiescent current maximum of 6.5 mA. While electrically equivalent, the Last Time Buy status indicates limited future availability. This option is suitable for applications where Tube packaging is preferred or where existing inventory management systems require this format.

Both substitute parts maintain ROHS3 compliance and MSL Level 1 rating, ensuring compatibility with modern manufacturing and environmental standards.

Frequently Asked Questions (FAQ)

Q: Can SN74F260DR and SN74F260D be used interchangeably with N74F260D,602?

A: Yes. Both Texas Instruments parts are electrically and mechanically equivalent. They share identical logic type, circuit count, input count, supply voltage range, output current specifications, input logic levels, propagation delay, operating temperature range, and package dimensions. All three parts are ROHS3 compliant with MSL Level 1 rating.

Q: What is the difference between SN74F260DR and SN74F260D?

A: The primary differences are packaging format and product status. SN74F260DR is supplied in Tape & Reel format with Active status, while SN74F260D is supplied in Tube format with Last Time Buy status. SN74F260D also specifies a maximum quiescent current of 6.5 mA. Electrical performance and package dimensions are identical.

Q: Why is the original N74F260D,602 marked as obsolete?

A: Obsolete status indicates the part is no longer manufactured by NXP USA Inc. and is no longer recommended for new designs. Substitute parts from active manufacturers ensure continued availability and support for new and existing applications.

Q: Are there any compatibility concerns when substituting these parts?

A: No compatibility concerns exist when substituting SN74F260DR or SN74F260D for N74F260D,602. All three parts use the same 14-SOIC package footprint, pin configuration, and electrical specifications. Direct board-level replacement is possible without design modifications.

Q: Which substitute should be selected for new production designs?

A: SN74F260DR is recommended for new production designs due to its Active product status, ensuring long-term supply availability. Tape & Reel packaging is optimized for automated assembly processes typical in modern manufacturing environments.
