Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TL3116IDG4 are qualified based on the following criteria:

Electrical Parameter Equivalence: All substitute parts maintain identical specifications for input offset voltage (3mV @ ±5V), input bias current (1.1µA @ ±5V), output current (20mA typical), quiescent current (15mA maximum), CMRR (100dB typical), and propagation delay (12ns maximum). Supply voltage range (5V ~ 10V, ±2.5V ~ 5V) and operating temperature range (-40°C ~ 85°C) are preserved across all qualified substitutes.

Functional Equivalence: All substitute parts are single-element general-purpose comparators with complementary push-pull TTL output configuration, ensuring functional compatibility in existing circuit designs.

Package Compatibility: All substitute parts utilize the 8-SOIC surface mount package (0.154", 3.90mm width), maintaining mechanical and thermal compatibility with existing PCB layouts.

Compliance Alignment: All substitute parts maintain ROHS3 compliance and MSL rating of 1 (Unlimited), ensuring regulatory and environmental compatibility.

Parameter Comparison

Engineering Selection Recommendations

TL3116ID: This part is electrically and functionally identical to the TL3116IDG4 with identical electrical specifications and 8-SOIC package configuration. However, TL3116ID is also classified as obsolete. This part is suitable for applications requiring exact electrical equivalence but does not address long-term procurement sustainability due to its obsolete status.

TL3116IDR: This part is the recommended substitute for the TL3116IDG4. It maintains complete electrical and functional equivalence across all specified parameters while carrying an active product status from Texas Instruments. The TL3116IDR provides procurement continuity and long-term availability assurance. All electrical characteristics, package specifications, compliance certifications, and operating parameters are identical to the TL3116IDG4, enabling direct substitution without circuit redesign.

Frequently Asked Questions (FAQ)

Q: Can TL3116ID be used as a direct replacement for TL3116IDG4?

A: Yes, TL3116ID is electrically and functionally equivalent to TL3116IDG4. Both parts share identical electrical specifications, output configuration, and 8-SOIC package. However, both parts are classified as obsolete. For new designs or long-term procurement, TL3116IDR is the preferred substitute due to its active product status.

Q: What is the difference between TL3116IDG4 and TL3116IDR?

A: The primary difference is product status: TL3116IDG4 is obsolete while TL3116IDR is active. All electrical parameters, functional characteristics, and package specifications are identical. TL3116IDR is the direct successor and recommended substitute for procurement and design continuity.

Q: Are there any package or pinout differences between these parts?

A: No. All three parts (TL3116IDG4, TL3116ID, and TL3116IDR) utilize the identical 8-SOIC surface mount package with 0.154" width (3.90mm). Pinout and mechanical compatibility are fully preserved across all variants.

Q: Can these parts be used interchangeably in existing designs?

A: Yes. TL3116ID and TL3116IDR are direct substitutes for TL3116IDG4 without requiring circuit modifications. All electrical specifications, supply voltage ranges, operating temperature ranges, and output characteristics are identical, enabling pin-for-pin replacement.

Q: What compliance certifications apply to substitute parts?

A: All substitute parts maintain ROHS3 compliance and MSL rating of 1 (Unlimited), matching the compliance profile of the original TL3116IDG4. No additional compliance considerations are required for substitution.
