The substitute parts TSM104WAID, TSM104WAIDR, and TSM104WIDR all maintain the core electrical performance characteristics and mechanical compatibility required for direct substitution in applications designed for the primary part number.

Parameter Comparison

Engineering Selection Recommendations

TSM104WAID (STMicroelectronics, Tube Packaging)

This part maintains active product status with the highest inventory availability at 1116 units. It is the primary selection for new designs and applications requiring tube packaging format. The part meets all ROHS3 compliance requirements and operates across the full specified supply voltage range of 3V to 32V. The MSL rating of 3 (168 hours) requires standard moisture control during storage and handling.

TSM104WAID (STMicroelectronics, Tube Packaging - Duplicate Entry)

This entry is identical to the primary part and represents the same component specification.

TSM104WAIDR (Texas Instruments, Tape & Reel Packaging)

This substitute is designated as Last Time Buy status, indicating limited future availability. It is suitable for high-volume manufacturing processes requiring tape and reel packaging format. The part exhibits improved moisture sensitivity characteristics with MSL rating of 1 (Unlimited), eliminating moisture control requirements. The maximum supply voltage specification is reduced to 30V, which remains compatible with applications designed for the primary part's 32V maximum rating. Current input bias specification increases to 30 nA, which remains within acceptable tolerance for general-purpose amplifier applications. Inventory availability is 3720 units.

TSM104WIDR (Texas Instruments, Tape & Reel Packaging)

This substitute is designated as Last Time Buy status. It is compatible with tape and reel packaging processes and provides the same MSL rating of 1 (Unlimited) as the TSM104WAIDR. The voltage input offset specification increases to 1 mV, which represents a deviation from the primary part's 500 µV specification. This parameter variation remains within acceptable limits for general-purpose amplifier applications. The maximum supply voltage is specified at 30V. Inventory availability is 1900 units.

Frequently Asked Questions (FAQ)

Q: Can TSM104WAIDR and TSM104WIDR be used interchangeably with TSM104WAID?

A: Both parts maintain the same core electrical performance characteristics including slew rate, gain bandwidth product, output current capability, and operating temperature range. The primary differences are packaging format (tape and reel versus tube), input bias current specification (30 nA versus 20 nA), and input offset voltage specification (500 µV to 1 mV). These variations fall within acceptable tolerance parameters for general-purpose amplifier applications. However, the reduced maximum supply voltage specification of 30V in the Texas Instruments parts requires verification that applications do not exceed this limit.

Q: What is the significance of the MSL rating difference between parts?

A: The TSM104WAID carries an MSL rating of 3 (168 hours), requiring moisture control during storage and handling. The TSM104WAIDR and TSM104WIDR carry an MSL rating of 1 (Unlimited), eliminating moisture sensitivity requirements. For manufacturing environments with controlled humidity, this difference has minimal impact. For applications with extended storage periods or high-humidity environments, the MSL 1 rated parts provide operational advantages.

Q: Why do the Texas Instruments parts have Last Time Buy status?

A: Last Time Buy status indicates that these parts are in the final stages of product lifecycle and will not be manufactured beyond a specified date. While current inventory is available, future procurement may not be possible. For new designs or long-term production requirements, the active status TSM104WAID from STMicroelectronics is the recommended selection.

Q: Are there packaging considerations for PCB assembly?

A: The TSM104WAID is supplied in tube packaging, suitable for manual assembly or lower-volume pick-and-place operations. The TSM104WAIDR and TSM104WIDR are supplied in tape and reel format, optimized for high-speed automated assembly processes. The physical package dimensions are identical (16-SOIC, 0.154" width, 3.90mm), so PCB footprints and reflow profiles remain unchanged across all three parts.

Q: What is the maximum supply voltage for each part?

A: The TSM104WAID supports a maximum supply voltage of 32V. The TSM104WAIDR and TSM104WIDR support a maximum supply voltage of 30V. Applications designed for the primary part operating at voltages between 30V and 32V require verification before substituting with the Texas Instruments alternatives.

Q: How do the input bias current specifications differ?

A: The TSM104WAID specifies 20 nA input bias current. The TSM104WAIDR and TSM104WIDR specify 30 nA input bias current. This 10 nA difference represents a 50% increase and may impact precision applications requiring extremely low input bias current. For general-purpose amplifier applications, this variation is typically acceptable.

Q: What is the difference between TSM104WAIDR and TSM104WIDR?

A: Both parts are manufactured by Texas Instruments and supplied in tape and reel packaging. The primary difference is the input offset voltage specification: TSM104WAIDR specifies 500 µV, while TSM104WIDR specifies 1 mV. For applications requiring tighter input offset voltage tolerance, the TSM104WAIDR is the appropriate selection. Both parts maintain identical slew rate, gain bandwidth product, and output current specifications.
