Substitute Part Grouping Explanation

Substitute parts for the 74LVC2G157DCUTE4 are identified based on strict parametric equivalence. The following criteria determine substitutability:

• Base product number: 74LVC2G157
• Circuit configuration: 1 x 2:1 multiplexer
• Package type: 8-VSSOP
• Voltage supply range: 1.65V ~ 5.5V
• Output current specifications: 32mA (High), 32mA (Low)
• Operating temperature range: -40°C ~ 85°C
• Compliance certifications: ROHS3, REACH Unaffected

All substitute parts listed maintain identical electrical and mechanical specifications. Differences exist only in packaging format (Cut Tape vs. Digi-Reel) and product status (Active vs. Discontinued/Obsolete).

Parameter Comparison

Engineering Selection Recommendations

For applications currently using the 74LVC2G157DCUTE4, the following selection criteria apply:

Active Status Priority: SN74LVC2G157DCUR and SN74LVC2G157DCUT are both Active products with full manufacturer support. These parts are preferred for new designs and ongoing production.

Inventory Availability: SN74LVC2G157DCUR offers the highest inventory level (35,300 Pcs), providing supply chain stability. SN74LVC2G157DCUT provides an alternative with moderate availability (4,267 Pcs).

Compliance Certification: All substitute parts maintain ROHS3 compliance and REACH Unaffected status, meeting regulatory requirements equivalent to the original part.

Packaging Format: SN74LVC2G157DCUR and SN74LVC2G157DCUT are supplied in Cut Tape (CT) & Digi-Reel format, standard for production environments. The 74LVC2G157DCURG4 is available but listed as Discontinued at DiGi Electronics.

Frequently Asked Questions (FAQ)

Q: Can SN74LVC2G157DCUR directly replace 74LVC2G157DCUTE4 in existing designs?

A: Yes. Both parts share identical electrical specifications (1.65V ~ 5.5V supply, 32mA output current, -40°C ~ 85°C operating range) and the same 8-VSSOP package. Pin configuration and functional behavior are equivalent.

Q: What is the difference between SN74LVC2G157DCUR and SN74LVC2G157DCUT?

A: Both parts are parametrically identical. The difference lies in packaging format and inventory availability. SN74LVC2G157DCUR is supplied in Digi-Reel format with higher stock levels, while SN74LVC2G157DCUT is supplied in Cut Tape format with lower availability.

Q: Why is 74LVC2G157DCUTE4 listed as Obsolete?

A: The original part number has reached end-of-life status. Texas Instruments continues to manufacture equivalent variants under different part numbers (SN74LVC2G157DCUR and SN74LVC2G157DCUT) that maintain full functional and electrical compatibility.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts carry ROHS3 Compliant certification and REACH Unaffected status, matching the compliance profile of the original 74LVC2G157DCUTE4.

Q: What is the Moisture Sensitivity Level for substitute parts?

A: All substitute parts maintain MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.
