Parameter Comparison

Engineering Selection Recommendations

TSM104WAID (STMicroelectronics)

The TSM104WAID is an active product from the original manufacturer, STMicroelectronics, with identical electrical specifications to the TSM104AID. This part maintains full parameter equivalence including input bias current, input offset voltage, and maximum supply voltage rating. The primary distinction is packaging format (Tube versus unspecified) and moisture sensitivity level (MSL 3 versus MSL 1). This substitute is suitable for applications where the original manufacturer continuity is required and moisture sensitivity handling procedures are implemented.

TSM104WAIDR (Texas Instruments)

The TSM104WAIDR is a cross-manufacturer substitute from Texas Instruments, currently in Last Time Buy status. Electrical specifications are equivalent with the exception of input bias current (30 nA versus 20 nA) and maximum supply voltage (30 V versus 32 V). The part is supplied in Tape & Reel packaging with MSL 1 rating. This substitute is applicable for applications where the reduced maximum supply voltage and slightly elevated input bias current are within design tolerances.

TSM104WIDR (Texas Instruments)

The TSM104WIDR is a cross-manufacturer substitute from Texas Instruments, currently in Last Time Buy status. This part exhibits equivalent electrical performance with the exception of input bias current (30 nA versus 20 nA), input offset voltage (1 mV versus 500 µV), and maximum supply voltage (30 V versus 32 V). The part is supplied in Tape & Reel packaging with MSL 1 rating. This substitute is applicable for applications where the elevated input offset voltage and reduced maximum supply voltage are within design tolerances.

Frequently Asked Questions (FAQ)

Q: Can TSM104WAID be used as a direct replacement for TSM104AID?

A: The TSM104WAID is electrically equivalent to the TSM104AID with identical core amplifier specifications. The primary differences are packaging format and moisture sensitivity level. Direct substitution is permissible provided that moisture handling procedures appropriate for MSL 3 are implemented during storage and assembly.

Q: What is the significance of the maximum supply voltage difference between TSM104AID (32 V) and the Texas Instruments substitutes (30 V)?

A: The TSM104AID supports a maximum supply voltage of 32 V, while TSM104WAIDR and TSM104WIDR support 30 V maximum. Applications operating at supply voltages between 30 V and 32 V cannot use the Texas Instruments variants without circuit redesign. Applications operating at 30 V or below are unaffected by this parameter difference.

Q: How do the input bias current specifications differ among the substitute parts?

A: The TSM104AID and TSM104WAID specify 20 nA input bias current. The TSM104WAIDR and TSM104WIDR specify 30 nA input bias current. Applications with stringent input bias current requirements must verify that the 30 nA specification is acceptable for their circuit design.

Q: What is the difference between TSM104WAIDR and TSM104WIDR?

A: Both parts are manufactured by Texas Instruments and supplied in Tape & Reel packaging. The primary electrical difference is input offset voltage: TSM104WAIDR specifies 500 µV (matching the original part), while TSM104WIDR specifies 1 mV. Applications requiring input offset voltage of 500 µV or lower must use TSM104WAIDR.

Q: Why is TSM104WAID in Active status while TSM104WAIDR and TSM104WIDR are in Last Time Buy status?

A: Product status reflects manufacturer production plans. TSM104WAID remains in active production by STMicroelectronics, ensuring continued availability. TSM104WAIDR and TSM104WIDR are in Last Time Buy status from Texas Instruments, indicating limited future availability. For long-term supply assurance, TSM104WAID is the preferred substitute.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. The TSM104AID and all three substitute parts (TSM104WAID, TSM104WAIDR, TSM104WIDR) are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: What packaging formats are available for these parts?

A: TSM104AID packaging format is not specified in the documentation. TSM104WAID is supplied in Tube packaging. TSM104WAIDR and TSM104WIDR are supplied in Tape & Reel (TR) packaging. Packaging selection affects handling, storage, and assembly processes.
