74F10SC NAND Gate IC Equivalent & Substitute Parts

Part Overview

The 74F10SC is a NAND Gate IC featuring 3 channels with 3 inputs per channel in a 14-SOIC surface mount package, manufactured by onsemi. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement continuity. The 74F series logic family provides standard TTL-compatible switching functionality suitable for digital logic applications requiring NAND gate operations.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the 74F10SC is determined by strict equivalence across the following critical parameters: logic type (NAND Gate), circuit count (3 channels), input count (3 inputs per channel), supply voltage range (4.5V ~ 5.5V), output current specifications (1mA high, 20mA low), input logic levels (0.8V low, 2V high), propagation delay (5ns @ 5V, 50pF), and operating temperature range (0°C ~ 70°C). Package compatibility and mounting type are secondary considerations; however, pin-compatible packages within the 14-SOIC family are acceptable substitutes. All substitute parts listed maintain full functional and electrical equivalence to the original 74F10SC.

Parameter Comparison

Engineering Selection Recommendations

SN74F10DR (Texas Instruments) is the primary direct substitute for the 74F10SC. This part maintains active product status with full ROHS3 compliance and identical electrical specifications. The 14-SOIC package dimensions (0.154", 3.90mm Width) match the original exactly, ensuring PCB layout compatibility without modification.

SN74F10NSR (Texas Instruments) provides functional equivalence with identical electrical parameters. The package variant (14-SO, 0.209", 5.30mm Width) represents a wider body SOIC package. This part is suitable for applications where PCB footprint adjustment is acceptable and inventory availability is prioritized.

SN74F10D (Texas Instruments) is classified as Last Time Buy status, indicating limited future availability. This part maintains full electrical and package equivalence to the original 74F10SC (14-SOIC, 0.154", 3.90mm Width) and carries ROHS3 compliance. Selection of this part should account for end-of-life procurement constraints.

For new designs and ongoing production, SN74F10DR is recommended due to active product status and assured long-term availability. For existing inventory management or cost optimization, SN74F10NSR and SN74F10D remain functionally equivalent alternatives.

Frequently Asked Questions (FAQ)

Q: Can SN74F10NSR be used as a direct replacement for 74F10SC on existing PCBs?

A: SN74F10NSR is electrically equivalent but features a wider 14-SO package (0.209" width) compared to the original 14-SOIC (0.154" width). PCB footprint modification is required. If PCB layout cannot be altered, use SN74F10DR or SN74F10D instead.

Q: What is the difference between SN74F10DR and SN74F10D?

A: Both parts are electrically and mechanically identical with matching 14-SOIC packages. The primary difference is product status: SN74F10DR is Active, while SN74F10D is Last Time Buy. For new procurement, SN74F10DR is preferred for supply continuity.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. SN74F10DR, SN74F10NSR, and SN74F10D all carry ROHS3 compliance certification. The original 74F10SC (onsemi) does not specify RoHS status in the provided data.

Q: Can these parts operate outside the 0°C ~ 70°C temperature range?

A: No. All listed parts, including the original 74F10SC, are specified for 0°C ~ 70°C operation. Applications requiring extended temperature ranges require alternative component selection.

Q: What is the significance of MSL Level 1 (Unlimited)?

A: MSL Level 1 indicates unlimited shelf life without moisture bake-out requirements. All listed parts share this classification, simplifying storage and handling procedures.

Q: Are pin assignments identical across all substitute parts?

A: Yes. All parts maintain the 74F series standard pinout for 3-channel, 3-input NAND gate configurations in 14-pin packages. Direct pin-for-pin substitution is supported.
