IH5042C/D Equivalent & Substitute Parts

Part Overview

The IH5042C/D is a single-circuit SPDT (Single Pole Double Throw) IC switch with 80Ohm on-state resistance, manufactured by Analog Devices Inc./Maxim Integrated. This die-form component operates with dual supply voltages (±4.5V to ±18V) and features a 2:1 multiplexer/demultiplexer configuration. The part is classified as obsolete, making identification of active equivalent components essential for new designs and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the IH5042C/D is determined by electrical and functional equivalence across the following critical parameters:

• Switch topology: SPDT configuration with 2:1 multiplexer/demultiplexer function
• On-state resistance: 80Ohm maximum specification
• Channel matching: 5Ohm typical ΔRon tolerance
• Supply voltage range: ±4.5V to ±18V dual supply operation
• Switching performance: 400ns maximum turn-on time, 200ns maximum turn-off time
• Leakage current: 5nA maximum off-state specification
• Operating temperature: 0°C to 70°C range
• Compliance standards: ROHS3 compliance and MSL Level 1 rating

The IH5042CWE+ represents the active production equivalent, maintaining identical electrical specifications while transitioning from die form to a 16-SOIC surface-mount package.

Parameter Comparison

Engineering Selection Recommendations

The IH5042CWE+ is the direct active equivalent for the obsolete IH5042C/D. Both components maintain identical electrical specifications and compliance certifications (ROHS3, MSL Level 1, REACH Unaffected status). The primary design consideration is the package transition from die form to 16-SOIC surface-mount configuration, which requires PCB layout modification but presents no electrical incompatibility.

Selection of the IH5042CWE+ is appropriate for applications requiring SPDT switching with 80Ohm on-state resistance, dual supply operation within the ±4.5V to ±18V range, and switching performance specifications of 400ns turn-on and 200ns turn-off times. The active product status ensures long-term availability and supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can the IH5042CWE+ directly replace the IH5042C/D in existing designs?

A: Electrical substitution is complete. The IH5042CWE+ maintains all specified electrical parameters. However, the package change from die to 16-SOIC requires PCB redesign and layout modifications. No circuit-level changes are necessary.

Q: What is the primary difference between these two parts?

A: The IH5042C/D is supplied as a bare die, while the IH5042CWE+ is packaged in a 16-SOIC surface-mount configuration. Electrical performance and specifications are identical.

Q: Are there any compliance or certification differences?

A: Both parts maintain ROHS3 compliance, MSL Level 1 rating, and REACH Unaffected status. No compliance differences exist between the two components.

Q: What are the critical parameters for substitution compatibility?

A: Substitution is valid when the following parameters match: SPDT switch topology, 2:1 multiplexer/demultiplexer configuration, 80Ohm on-state resistance, ±4.5V to ±18V dual supply voltage range, 400ns/200ns switching times, and 5nA maximum leakage current.

Q: Is the 16-SOIC package suitable for high-density PCB layouts?

A: The 16-SOIC package (0.295" width, 7.50mm) is a standard surface-mount configuration. PCB layout feasibility depends on specific design constraints and available board space.
