TL851CDRG4 Equivalent & Substitute Parts

Part Overview

The TL851CDRG4 is a sonar ranging control IC manufactured by Texas Instruments, designed for RF applications operating in the 20kHz to 90kHz frequency range. This component features synchronous 4-bit gain control and is packaged in a 16-SOIC surface mount configuration. The TL851CDRG4 is currently discontinued at DiGi Electronics, necessitating identification of functionally equivalent alternatives for ongoing design requirements and production needs.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TL851CDRG4 is determined by strict adherence to the following electrical and mechanical parameters:

• Frequency Range: 20kHz ~ 90kHz (exact match required)
• RF Type: Sonar Control (functional category match required)
• Package / Case: 16-SOIC (0.154", 3.90mm Width) (mechanical compatibility required)
• Mounting Type: Surface Mount (assembly compatibility required)
• RoHS Status: ROHS3 Compliant (regulatory compliance required)
• Moisture Sensitivity Level: 1 (Unlimited) (handling and storage compatibility required)

The TL851CDR meets all substitution criteria as an active product from the same manufacturer within the same base product family (TL851), maintaining electrical and mechanical compatibility while offering improved availability.

Parameter Comparison

Engineering Selection Recommendations

The TL851CDR is the qualified substitute for the discontinued TL851CDRG4. Both components share identical electrical specifications across frequency range, RF type classification, and sonar control functionality. Mechanical compatibility is assured through identical 16-SOIC packaging and surface mount configuration. Regulatory compliance is maintained with matching ROHS3 and REACH certifications. The TL851CDR offers the additional advantage of active product status with established supply chain availability, making it the appropriate selection for applications requiring the TL851CDRG4.

Frequently Asked Questions (FAQ)

Q: Can the TL851CDR directly replace the TL851CDRG4 in existing designs?

A: Yes. Both components share identical package geometry (16-SOIC), mounting type (surface mount), frequency range (20kHz ~ 90kHz), and RF classification (sonar control). Pin-level compatibility is maintained within the TL851 base product family.

Q: What is the difference between the TL851CDRG4 and TL851CDR?

A: The primary difference is product status. The TL851CDRG4 is discontinued, while the TL851CDR is active. The TL851CDR is specified as a sonar ranging receiver with TTL-compatible interface, whereas the TL851CDRG4 features synchronous 4-bit gain control. Both operate within the identical frequency range and package specification.

Q: Are there any compliance or regulatory differences between these parts?

A: No. Both components maintain identical RoHS3 compliance, REACH unaffected status, and moisture sensitivity level (MSL 1 - Unlimited). Regulatory requirements are satisfied equally by either component.

Q: What packaging options are available for the TL851CDR?

A: The TL851CDR is available in Cut Tape (CT) and Digi-Reel® packaging formats, providing flexibility for both prototype and production volume requirements.

Q: Is the TL851CDR suitable for new design implementations?

A: Yes. The TL851CDR is an active product with established supply chain availability, making it appropriate for new designs requiring sonar ranging control functionality in the 20kHz to 90kHz frequency band.
