SN74AUC1G19DBVT Equivalent & Substitute Parts

Part Overview

The SN74AUC1G19DBVT is a single decoder/demultiplexer integrated circuit manufactured by Texas Instruments, configured as a 1 x 1:2 logic decoder in a SOT-23-6 surface mount package. This device is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing design support, maintenance, and production continuity. The obsolete status necessitates sourcing from alternative stock channels or identifying active production equivalents that maintain identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SN74AUC1G19DBVT is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Criteria:

• Decoder/Demultiplexer circuit topology: 1 x 1:2 configuration
• Voltage supply range: 0.8V ~ 2.7V (single supply)
• Output current specifications: 9mA high, 9mA low
• Operating temperature range: -40°C ~ 85°C

Mechanical Equivalence Criteria:

• Package type: SOT-23-6
• Mounting method: Surface Mount
• Pin count and pinout compatibility

Compliance Equivalence Criteria:

• RoHS3 compliance
• MSL rating: 1 (Unlimited)
• REACH status: Unaffected

Parts meeting all these parameters are classified as parametric equivalents and direct substitutes. Packaging format (bulk versus tape & reel) does not affect functional or electrical equivalence.

Parameter Comparison

Engineering Selection Recommendations

The SN74AUC1G19DBVR is a direct parametric equivalent to the SN74AUC1G19DBVT. Both parts share identical electrical specifications, mechanical packaging, and compliance certifications. The primary distinction is product status: the DBVT variant is obsolete, while the DBVR variant maintains active production status from Texas Instruments.

For new designs or production continuity, the SN74AUC1G19DBVR is the appropriate selection. Both parts are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements. The packaging format difference (bulk versus tape & reel) reflects supply chain configuration only and does not affect functional performance or circuit compatibility.

Frequently Asked Questions (FAQ)

Q: Can the SN74AUC1G19DBVR directly replace the SN74AUC1G19DBVT in existing designs?

A: Yes. Both parts are electrically and mechanically identical. They share the same SOT-23-6 pinout, voltage specifications (0.8V ~ 2.7V), output current ratings (9mA), and operating temperature range (-40°C ~ 85°C). No circuit modifications are required.

Q: What is the difference between the DBVT and DBVR part numbers?

A: The suffix indicates packaging format. DBVT denotes bulk packaging, while DBVR denotes tape & reel (TR) packaging. The functional device is identical; the difference is in supply format only.

Q: Why is the SN74AUC1G19DBVT listed as obsolete?

A: Obsolete status indicates Texas Instruments has discontinued active production of this specific part number variant. The SN74AUC1G19DBVR remains in active production and serves as the current equivalent.

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

A: No. Both parts carry identical certifications: ROHS3 compliance, MSL rating 1 (Unlimited), and REACH unaffected status.

Q: Can I use these parts interchangeably in high-volume production?

A: Yes, provided your supply chain accommodates the packaging format. The DBVR tape & reel format is standard for automated assembly processes. Verify tape specifications with your assembly partner if transitioning from bulk to reel format.
