TS419ID Equivalent & Substitute Parts

Part Overview

The TS419ID is a Class AB mono amplifier IC manufactured by STMicroelectronics, housed in an 8-SOIC surface mount package. This device delivers 367mW output power at 16Ohm load with a supply voltage range of 2V to 5.5V. The TS419ID is classified as obsolete, making identification of equivalent and substitute parts essential for ongoing design support and production continuity. Substitute parts must maintain functional equivalence in amplifier topology, output power delivery, package form factor, and electrical operating parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TS419ID are selected based on strict electrical and mechanical compatibility criteria. The primary substitution parameters are:

Electrical Compatibility:

• Amplifier topology: Class AB mono configuration
• Output power capability: minimum 350mW at 16Ohm load (within acceptable range of original 367mW specification)
• Supply voltage range: 2V to 5.5V (identical to main part)
• Operating temperature range: -40°C to 85°C (identical to main part)
• Package form factor: 8-SOIC with 0.154" (3.90mm) width (identical to main part)

Regulatory Compliance:

• RoHS3 compliance required
• REACH unaffected status required
• Surface mount technology for PCB integration

The substitute parts LM4818MX/NOPB and LM4819MX/NOPB from Texas Instruments meet all electrical and mechanical parameters. Both devices are active products with superior moisture sensitivity ratings (MSL 1 versus MSL 3), ensuring better long-term reliability and availability compared to the obsolete TS419ID.

Parameter Comparison

Engineering Selection Recommendations

LM4819MX/NOPB is the primary substitute for TS419ID applications. This device maintains identical electrical operating parameters (supply voltage, temperature range, output power within specification) and identical package form factor. The LM4819MX/NOPB includes differential inputs and shutdown features, matching the feature set of the original TS419ID. Active product status ensures long-term availability and supply chain continuity. Superior moisture sensitivity rating (MSL 1) provides enhanced reliability for storage and handling.

LM4818MX/NOPB is an alternative substitute when differential input capability is not required. This device delivers equivalent output power and maintains all other electrical and mechanical specifications. The LM4818MX/NOPB includes depop and shutdown features. Active product status and MSL 1 rating provide equivalent reliability advantages.

Both substitute parts are ROHS3 compliant and REACH unaffected, meeting regulatory requirements identical to the original TS419ID. Selection between LM4819MX/NOPB and LM4818MX/NOPB depends on circuit requirements for differential input functionality.

Frequently Asked Questions (FAQ)

Q: Can LM4818MX/NOPB or LM4819MX/NOPB be used as direct replacements for TS419ID in existing designs?

A: Both devices are direct pin-compatible substitutes. The 8-SOIC package dimensions are identical. Electrical operating parameters (supply voltage, temperature range, output power) are equivalent. Verify differential input requirements in your circuit design to select between LM4818MX/NOPB (single-ended inputs) and LM4819MX/NOPB (differential inputs).

Q: What is the output power difference between TS419ID (367mW) and the substitute parts (350mW)?

A: The substitute parts deliver 350mW at 16Ohm load, compared to 367mW for the TS419ID. This 17mW difference represents a 4.6% reduction in maximum output power. Verify that your application can operate within this reduced power specification before implementation.

Q: Why is the moisture sensitivity level (MSL) different between TS419ID and the substitute parts?

A: The TS419ID has MSL 3 (168 hours maximum floor life), while LM4818MX/NOPB and LM4819MX/NOPB have MSL 1 (unlimited floor life). MSL 1 rating indicates superior moisture resistance and longer shelf life, providing advantages for inventory management and long-term storage.

Q: Are the substitute parts available in the same packaging options as TS419ID?

A: LM4818MX/NOPB and LM4819MX/NOPB are supplied in Cut Tape (CT) and Digi-Reel® packaging. Both devices use the 8-SOIC package form factor identical to TS419ID. Verify packaging format requirements for your procurement and assembly processes.

Q: What features differ between LM4818MX/NOPB and LM4819MX/NOPB?

A: LM4819MX/NOPB includes differential inputs and shutdown functionality. LM4818MX/NOPB includes depop and shutdown functionality. Both devices include shutdown capability. Select LM4819MX/NOPB if your circuit design requires differential input configuration; otherwise, LM4818MX/NOPB is suitable.

Q: Are both substitute parts RoHS3 compliant?

A: Yes. Both LM4818MX/NOPB and LM4819MX/NOPB are ROHS3 compliant and REACH unaffected, matching the regulatory compliance status of TS419ID.

Q: What is the product status difference between TS419ID and the substitute parts?

A: TS419ID is classified as obsolete, indicating discontinued manufacturing and limited availability. LM4818MX/NOPB and LM4819MX/NOPB are active products with ongoing manufacturing and guaranteed long-term supply availability.
