TLV2452CDGK Equivalent & Substitute Parts

Part Overview

The TLV2452CDGK is a general-purpose operational amplifier manufactured by Texas Instruments, featuring dual circuits in a rail-to-rail output configuration. This device is classified as an active linear amplifier component and is currently in active product status. The TLV2452CDGK is packaged in an 8-VSSOP surface-mount package and is RoHS3 compliant with unlimited moisture sensitivity rating.

Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be achieved within the specified parameter ranges. Alternative components may be required due to inventory availability, packaging format preferences, or extended operating temperature requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TLV2452CDGK are qualified based on the following electrical and mechanical compatibility criteria:

Functional Equivalence Requirements:

• Dual-circuit general-purpose operational amplifier configuration
• Rail-to-rail output capability
• Surface-mount package with 8-pin TSSOP/MSOP footprint (0.118", 3.00mm width)
• RoHS3 compliance and MSL Level 1 rating

Electrical Parameter Tolerance Ranges:

• Slew rate within ±5% of specified value
• Gain bandwidth product within ±10% of specified value
• Input bias current at or below specified maximum
• Input offset voltage at or below specified maximum
• Supply current within ±15% of specified value
• Output current per channel at or above specified minimum
• Supply voltage span encompassing or exceeding the original specification

Operating Conditions:

• Operating temperature range must support the original 0°C to 70°C specification or extend beyond it

The MAX4163EUA+ and MAX4163EUA+T variants meet these criteria and are classified as manufacturer-recommended substitutes.

Engineering Selection Recommendations

TLV2452CDGK (Original Part)

The TLV2452CDGK remains the primary selection when the specified electrical characteristics and operating temperature range of 0°C to 70°C are required. This device is active in production status with 2990 units in current inventory. The component is RoHS3 compliant and carries unlimited moisture sensitivity rating, suitable for standard industrial and commercial applications.

MAX4163EUA+ (Tube Packaging)

The MAX4163EUA+ is a direct functional equivalent available in tube packaging format. This variant provides extended operating temperature range (-40°C to 85°C), higher maximum supply voltage (10 V versus 6 V), and improved output current capability (15 mA versus 10 mA per channel). The substitute maintains identical mechanical compatibility with 8-TSSOP/8-MSOP footprint. RoHS3 compliance and MSL Level 1 rating are preserved. Inventory availability is 3100 units.

MAX4163EUA+T (Tape & Reel Packaging)

The MAX4163EUA+T is functionally identical to the MAX4163EUA+ but supplied in tape and reel format for automated assembly processes. Electrical specifications, operating temperature range, and compliance certifications are equivalent. This variant is recommended for high-volume production environments requiring continuous-feed component handling. Inventory availability is 3800 units.

Both MAX4163 variants are active products from Analog Devices Inc./Maxim Integrated and carry identical regulatory compliance status (RoHS3, REACH Unaffected, EAR99 ECCN classification).

Frequently Asked Questions (FAQ)

Q: Can the MAX4163EUA+ be used as a direct replacement for the TLV2452CDGK in all applications?

A: The MAX4163EUA+ and MAX4163EUA+T are electrically compatible substitutes within the specified parameter ranges. Both devices feature identical dual-circuit, rail-to-rail general-purpose amplifier architecture and share the same 8-TSSOP/8-MSOP footprint. The substitute parts provide enhanced performance characteristics including lower input bias current (1 pA versus 500 pA), higher output current capability (15 mA versus 10 mA per channel), and extended supply voltage range (2.5 V to 10 V versus 2.7 V to 6 V). Applications operating within the original 0°C to 70°C temperature range will function identically with either part.

Q: What is the difference between MAX4163EUA+ and MAX4163EUA+T?

A: The MAX4163EUA+ and MAX4163EUA+T are electrically and functionally identical. The primary distinction is packaging format: MAX4163EUA+ is supplied in tube packaging, while MAX4163EUA+T is supplied in tape and reel format. Tube packaging is suitable for manual assembly and lower-volume applications. Tape and reel packaging is designed for automated pick-and-place assembly systems and high-volume production environments. Selection between these variants depends on manufacturing process requirements rather than electrical performance.

Q: Are there any temperature range limitations when substituting the MAX4163 for the TLV2452CDGK?

A: The TLV2452CDGK operates from 0°C to 70°C. The MAX4163EUA+ and MAX4163EUA+T extend this range to -40°C to 85°C. Applications requiring operation below 0°C or above 70°C must use the MAX4163 variants. For applications within the original 0°C to 70°C specification, both the original and substitute parts are qualified.

Q: Do the substitute parts maintain the same pin configuration and footprint?

A: Yes. The MAX4163EUA+ and MAX4163EUA+T use identical 8-pin TSSOP/MSOP package with 0.118" (3.00mm) width. Pin configuration and PCB footprint are mechanically compatible with the TLV2452CDGK. No layout modifications are required for substitution.

Q: What are the compliance and regulatory differences between these parts?

A: All three parts (TLV2452CDGK, MAX4163EUA+, and MAX4163EUA+T) are RoHS3 compliant, carry MSL Level 1 (unlimited) moisture sensitivity rating, and are REACH unaffected. All are classified under ECCN EAR99 and HTSUS 8542.33.0001. No regulatory or compliance barriers exist for substitution.

Q: How do the electrical specifications compare for critical parameters?

A: The MAX4163 variants provide superior input bias current performance (1 pA versus 500 pA) and higher output current per channel (15 mA versus 10 mA). Supply current is marginally higher (25 µA versus 23 µA per dual channels). Slew rate is slightly improved (0.115 V/µs versus 0.11 V/µs). Gain bandwidth product is slightly lower (200 kHz versus 220 kHz). Input offset voltage is higher (500 µV versus 300 µV). These differences are within acceptable tolerance ranges for general-purpose amplifier applications.

Q: What inventory considerations should guide part selection?

A: Current inventory levels are: TLV2452CDGK (2990 units in tube), MAX4163EUA+ (3100 units in tube), and MAX4163EUA+T (3800 units in tape & reel). Selection based on packaging format and immediate availability is appropriate when application requirements are met by all three variants.
