TS952IN Equivalent & Substitute Parts

Part Overview

The TS952IN is a general-purpose operational amplifier manufactured by STMicroelectronics, configured as a dual-channel (2 circuit) integrated circuit in an 8-Mini DIP through-hole package. This device features rail-to-rail output capability and is qualified to AEC-Q100 automotive standards with ROHS3 compliance.

The TS952IN is classified as an obsolete product. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support legacy system maintenance where this component is specified in existing applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TS952IN is determined by the following critical parameters:

Mechanical Compatibility:

• Package type: 8-DIP (0.300", 7.62mm) through-hole configuration
• Pin count and footprint must match for direct board-level replacement

Functional Compatibility:

• Dual-channel (2 circuit) configuration required
• Rail-to-rail output capability
• General-purpose amplifier topology

Electrical Operating Range:

• Supply voltage span: minimum 2.7 V to maximum 12 V
• Operating temperature range: -40°C to 125°C
• Output current capability: minimum 10 mA per channel

Regulatory & Compliance:

• RoHS3 compliance
• Automotive-grade qualification (AEC-Q100) preferred for applications requiring automotive standards

The ALD2702APAL is identified as a substitute part. While this device maintains the same physical package (8-DIP) and dual-channel configuration, it operates within a narrower supply voltage range (4 V to 10 V) and temperature range (0°C to 70°C), which restricts its use to applications within these constraints.

Parameter Comparison

Engineering Selection Recommendations

For Direct Substitution (Identical Operating Conditions):

The ALD2702APAL is suitable as a direct substitute only when the application operates within the following constraints:

• Supply voltage range: 4 V to 10 V (narrower than TS952IN specification)
• Operating temperature range: 0°C to 70°C (narrower than TS952IN specification)
• Output current requirement: 8 mA per channel or less

For Automotive or Extended Temperature Applications:

The TS952IN carries AEC-Q100 automotive qualification. The ALD2702APAL does not carry automotive qualification. Applications requiring automotive-grade components or extended temperature operation (-40°C to 125°C) cannot use the ALD2702APAL as a substitute.

For Low Supply Voltage Applications:

The TS952IN supports operation at 2.7 V minimum supply voltage. The ALD2702APAL requires a minimum of 4 V. Applications operating below 4 V supply voltage cannot use the ALD2702APAL.

Product Status Consideration:

The TS952IN is obsolete. The ALD2702APAL is active and available. For new designs or long-term supply assurance, the ALD2702APAL is the preferred choice when operating parameters align with its specifications.

Frequently Asked Questions (FAQ)

Q: Can the ALD2702APAL replace the TS952IN in all applications?

A: No. The ALD2702APAL operates within a narrower supply voltage range (4 V to 10 V versus 2.7 V to 12 V) and narrower temperature range (0°C to 70°C versus -40°C to 125°C). Substitution is valid only when the application operates within both the ALD2702APAL's voltage and temperature specifications.

Q: Is the ALD2702APAL suitable for automotive applications?

A: The ALD2702APAL is not qualified to AEC-Q100 automotive standards. The TS952IN carries AEC-Q100 qualification. For automotive applications, the TS952IN or an equivalent automotive-qualified alternative is required.

Q: Are the packages physically identical?

A: Yes. Both the TS952IN and ALD2702APAL use the 8-DIP (0.300", 7.62mm) through-hole package. Pin-to-pin compatibility is maintained, allowing direct board-level replacement from a mechanical standpoint.

Q: What are the key electrical differences between these parts?

A: The ALD2702APAL features higher slew rate (2.8 V/µs versus 1 V/µs) and lower input bias current (1 pA versus 35 nA), but lower gain bandwidth product (1.5 MHz versus 3 MHz) and reduced output current per channel (8 mA versus 10 mA). Supply current consumption is higher in the ALD2702APAL (2 mA versus 950 µA).

Q: Can I use the TS952IN in place of the ALD2702APAL?

A: The TS952IN is obsolete and not recommended for new designs. However, if the TS952IN is already in inventory and the application requirements are met, it can be used. The TS952IN's broader operating range makes it compatible with more applications than the ALD2702APAL.

Q: What compliance certifications do both parts carry?

A: Both the TS952IN and ALD2702APAL are ROHS3 compliant and REACH unaffected. The TS952IN additionally carries AEC-Q100 automotive qualification, which the ALD2702APAL does not possess.

Q: Are there any moisture sensitivity concerns with these parts?

A: Both parts carry Moisture Sensitivity Level (MSL) 1, indicating unlimited moisture sensitivity. Standard handling and storage practices for electronic components apply.
