Substitute Part Grouping Explanation

Substitution for the SN74LVC1G86DBVRG4 is determined by the following critical parameters:

Logic function: XOR gate with 1 channel and 2 inputs
Supply voltage range: 1.65V ~ 5.5V
Output drive capability: 32mA high and low
Propagation delay: 4ns @ 5V, 50pF
Operating temperature range: -40°C ~ 125°C
Surface mount packaging compatibility
RoHS3 compliance and MSL rating

Substitute parts are grouped into two categories: parametric equivalents (identical electrical specifications and packaging) and manufacturer-recommended alternatives (functionally equivalent with minor packaging or performance variations).

Engineering Selection Recommendations

Direct Parametric Equivalents (Recommended First Choice):

SN74LVC1G86DBVR and SN74LVC1G86DBVT are direct parametric equivalents manufactured by Texas Instruments with identical electrical specifications to the SN74LVC1G86DBVRG4. Both are active products with RoHS3 compliance and MSL rating of 1. The primary difference is packaging format: DBVR uses Cut Tape & Digi-Reel®, while DBVT uses Tape & Reel. SN74LVC1G86DBVR has significantly higher inventory availability (30700 Pcs).

Nexperia Alternatives:

74LVC1G86GW,125 and 74LVC1G86GV,125 are manufacturer-recommended alternatives from Nexperia USA Inc. Both maintain the 74LVC series designation and identical propagation delay. The GW variant uses 5-TSSOP packaging with lower quiescent current (4 µA), while the GV variant uses SC-74A packaging matching the original footprint. Both support the full -40°C to 125°C temperature range and are RoHS3 compliant.

onsemi Alternative:

NC7SZ86M5X from onsemi is functionally equivalent with superior quiescent current performance (2 µA). However, it operates at a reduced temperature range (-40°C to 85°C) and exhibits slightly higher propagation delay (5.4ns). This part is suitable for applications not requiring the full 125°C upper temperature limit.

Diodes Incorporated Alternative:

74LVC1G86W5-7 maintains electrical equivalence but uses SOT-25 packaging and exhibits significantly higher quiescent current (200 µA). This part is suitable only for applications where power consumption is not a constraint.

Frequently Asked Questions (FAQ)

Q: Can I directly replace SN74LVC1G86DBVRG4 with SN74LVC1G86DBVR?

A: Yes. SN74LVC1G86DBVR is a direct parametric equivalent with identical electrical specifications, supply voltage range, propagation delay, and operating temperature. The only difference is packaging format (Cut Tape & Digi-Reel® vs. the original). Both are RoHS3 compliant with MSL rating of 1.

Q: What is the difference between the Texas Instruments variants?

A: SN74LVC1G86DBVR and SN74LVC1G86DBVT are electrically identical. DBVR is supplied in Cut Tape & Digi-Reel® format, while DBVT is supplied in Tape & Reel format. Selection depends on your procurement and assembly requirements.

Q: Can I use the Nexperia 74LVC1G86GW,125 instead?

A: Yes, with packaging considerations. The GW variant uses 5-TSSOP packaging instead of SOT-23-5, requiring PCB layout changes. Electrical specifications are equivalent, including propagation delay and temperature range. Quiescent current is lower (4 µA vs. 10 µA), which is beneficial for power-sensitive applications.

Q: Is the onsemi NC7SZ86M5X suitable for my application?

A: NC7SZ86M5X is functionally equivalent with superior quiescent current (2 µA). However, it operates only to 85°C maximum, not 125°C. Use this part only if your application does not require the full temperature range and if the slightly higher propagation delay (5.4ns vs. 4ns) is acceptable.

Q: Why does 74LVC1G86W5-7 have higher quiescent current?

A: The Diodes Incorporated variant uses SOT-25 packaging and exhibits 200 µA quiescent current, significantly higher than other alternatives. This part is suitable only for non-power-critical applications. For power-sensitive designs, select SN74LVC1G86DBVR, 74LVC1G86GV,125, or NC7SZ86M5X.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts are RoHS3 compliant with MSL rating of 1 (Unlimited), matching the original part's compliance status.

Q: What packaging considerations apply to substitution?

A: The original SN74LVC1G86DBVRG4 uses SOT-23-5 packaging. Direct equivalents (SN74LVC1G86DBVR, SN74LVC1G86DBVT) maintain this package. Nexperia alternatives use 5-TSSOP (GW) or SC-74A (GV), requiring PCB layout verification. The Diodes part uses SOT-25. Confirm footprint compatibility before selection.
