XC74WL86AASR Equivalent & Substitute Parts

Part Overview

The XC74WL86AASR is a 2-channel, 2-input XOR (Exclusive OR) logic gate IC manufactured by Torex Semiconductor Ltd in 8-MSOPB surface mount packaging. This device operates across a 2V to 5.5V supply voltage range with low quiescent current of 1 µA maximum and propagation delay of 8.8ns at 5V with 50pF load. The XC74WL86AASR is classified as obsolete product status. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support long-term production requirements for applications utilizing this logic function.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the XC74WL86AASR is determined by strict equivalence in the following parameters:

Functional Equivalence: Logic type (XOR), number of circuits (2), and number of inputs (2) must be identical.

Electrical Compatibility: Supply voltage range must encompass or exceed the original specification (2V ~ 5.5V). Quiescent current must not exceed 1 µA maximum. Output current capability (8mA minimum for both high and low states) must be met or exceeded. Input logic levels and propagation delay characteristics must support the original application requirements.

Physical Compatibility: Surface mount packaging with 8-pin TSSOP or MSOP configuration. Pin count and footprint must be compatible with the original PCB design.

Compliance & Availability: Substitute parts must maintain ROHS3 compliance and REACH unaffected status. Active product status is preferred to ensure long-term supply availability.

The 74HC2G86DP,125 manufactured by Nexperia USA Inc. meets all substitution criteria as a direct functional and electrical equivalent with enhanced specifications and active product status.

Parameter Comparison

Engineering Selection Recommendations

The 74HC2G86DP,125 is a direct functional substitute for the obsolete XC74WL86AASR based on the following engineering criteria:

Product Status: The XC74WL86AASR is obsolete, creating supply chain risk. The 74HC2G86DP,125 maintains active product status with 17,132 pieces in stock, ensuring long-term availability and production continuity.

Compliance Alignment: Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for equivalent component selection.

Functional Equivalence: Both devices provide identical XOR logic functionality with 2 channels and 2 inputs per channel, ensuring pin-for-pin compatibility at the logic level.

Electrical Performance: The 74HC2G86DP,125 operates across a wider supply voltage range (2V ~ 6V versus 2V ~ 5.5V) and maintains identical quiescent current specifications. Output current capability is reduced (5.2mA versus 8mA), and propagation delay is increased (17ns versus 8.8ns). These differences must be evaluated against specific application load and timing requirements.

Thermal Performance: The 74HC2G86DP,125 supports an extended operating temperature range (-40°C ~ 125°C versus -40°C ~ 85°C), providing additional margin for high-temperature applications.

Packaging Compatibility: Both parts use 8-TSSOP surface mount packaging with compatible pinouts. Package width variation (3.00mm versus 2.80mm) is within standard PCB design tolerances for TSSOP footprints.

Frequently Asked Questions (FAQ)

Q: Can the 74HC2G86DP,125 be used as a direct replacement for the XC74WL86AASR?

A: The 74HC2G86DP,125 is functionally equivalent and pin-compatible. However, application-specific verification is required for output current and propagation delay specifications. If the original design operates at maximum output current (8mA) or requires propagation delay below 17ns, the reduced specifications of the substitute must be evaluated against actual circuit requirements.

Q: What are the key differences between these two parts?

A: The primary differences are: (1) Product status—XC74WL86AASR is obsolete while 74HC2G86DP,125 is active; (2) Output current—8mA versus 5.2mA; (3) Propagation delay—8.8ns versus 17ns; (4) Operating temperature range—85°C versus 125°C maximum; (5) Supply voltage range—5.5V versus 6V maximum. All other parameters including logic type, circuit count, input count, quiescent current, and packaging are equivalent.

Q: Are there any package compatibility concerns?

A: Both parts use 8-TSSOP surface mount packaging with identical pinouts. The package width differs slightly (2.80mm versus 3.00mm), but this variation is within standard PCB design tolerances for TSSOP footprints. No PCB redesign is required for package substitution.

Q: What compliance certifications apply to the substitute part?

A: The 74HC2G86DP,125 maintains ROHS3 compliance and REACH unaffected status, identical to the original XC74WL86AASR. Both parts satisfy equivalent regulatory requirements for component selection.

Q: How does the propagation delay difference affect circuit performance?

A: The 74HC2G86DP,125 exhibits 17ns propagation delay at 6V with 50pF load, compared to 8.8ns for the XC74WL86AASR at 5V with 50pF load. This represents approximately 93% longer delay. Applications with strict timing requirements must verify that the substitute delay specification does not violate system timing constraints.

Q: Is the reduced output current of the substitute part a concern?

A: The 74HC2G86DP,125 provides 5.2mA output current versus 8mA for the original part. This reduction must be evaluated against actual load requirements. If the circuit drives loads requiring more than 5.2mA per output, the substitute is not suitable without additional buffering.

Q: What is the inventory status for each part?

A: The XC74WL86AASR has 774 pieces in stock but is obsolete. The 74HC2G86DP,125 has 17,132 pieces in stock and maintains active product status, providing superior long-term supply availability.
