Substitute Part Grouping Explanation

The TLC339IDR qualifies as a direct substitute for the TLC339IDRG4 based on the following substitution criteria:

Electrical Compatibility: Both parts share identical electrical specifications including supply voltage range (3V ~ 16V), input offset voltage (5mV @ 10V), input bias current (5pA @ 5V), output current (20mA typical), quiescent current (125µA maximum), CMRR (84dB typical), propagation delay (4.5µs maximum), and operating temperature range (-40°C ~ 85°C).

Mechanical Compatibility: Both parts use the 14-SOIC package with identical dimensions (0.154", 3.90mm width) and surface-mount mounting type, ensuring PCB footprint compatibility.

Functional Equivalence: Both devices contain four general-purpose comparator elements with CMOS open-drain outputs, maintaining identical functional architecture.

Regulatory Compliance: Both parts carry ROHS3 compliance, REACH unaffected status, and identical moisture sensitivity level (MSL 1 - Unlimited).

Product Status Distinction: The primary difference is product status—TLC339IDRG4 is obsolete while TLC339IDR is active, making TLC339IDR the recommended procurement choice.

Parameter Comparison

Engineering Selection Recommendations

The TLC339IDR is the appropriate selection for applications currently specified with TLC339IDRG4. The substitute part maintains full electrical and mechanical compatibility while offering the advantage of active product status, ensuring long-term availability and manufacturing support from Texas Instruments.

The packaging difference—tube for TLC339IDRG4 versus tape & reel for TLC339IDR—reflects standard industry practice for active products and does not affect component functionality or PCB assembly compatibility. Both packaging formats are suitable for surface-mount assembly processes.

Both parts satisfy ROHS3 compliance requirements and carry identical regulatory certifications (REACH unaffected, MSL 1), making them interchangeable from a compliance perspective.

Frequently Asked Questions (FAQ)

Q: Can TLC339IDR directly replace TLC339IDRG4 on existing PCBs?

A: Yes. Both parts use the 14-SOIC package with identical pin configuration, footprint dimensions, and electrical specifications. No PCB modifications are required.

Q: What is the primary reason for substitution?
