ISL84541IP Equivalent & Substitute Parts

Part Overview

The ISL84541IP is a dual-circuit SPST-NO (Single Pole Single Throw - Normally Open) analog switch manufactured by Renesas Electronics Corporation. This 8-DIP through-hole component features 60Ohm on-state resistance and operates across a 2.7V to 12V single supply range. The ISL84541IP is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support, design updates, and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ISL84541IP is determined by the following critical parameters:

• Switch Circuit Configuration: SPST - NO topology with 2 circuits
• On-State Resistance: 60Ohm maximum
• Channel-to-Channel Matching: 800mOhm tolerance
• Package Type: 8-DIP through-hole form factor
• Supply Voltage Range: Minimum 2.7V to 12V compatibility
• Leakage Current: 100pA maximum specification
• Operating Temperature Range: Overlap with -40°C to 85°C

The identified substitute parts (MAX323CPA+ and MAX323EPA+) maintain identical switch circuit topology, circuit count, on-state resistance, and physical packaging. Both alternatives are manufactured by Analog Devices Inc./Maxim Integrated and preserve the core electrical characteristics required for direct functional replacement in through-hole PCB applications.

Parameter Comparison

Engineering Selection Recommendations

MAX323CPA+ is the primary recommended substitute. This part maintains active product status with ROHS3 compliance, ensuring long-term availability and regulatory alignment. The MAX323CPA+ operates across an extended supply voltage range (2.7V to 16V), providing superior compatibility with systems requiring higher supply voltages. Switch timing specifications (150ns, 100ns) are slightly slower than the ISL84541IP but remain within acceptable margins for most analog switching applications. Channel capacitance is marginally higher (9pF vs. 8pF), and crosstalk performance is -85dB versus -90dB, representing minor trade-offs offset by active product status and modern compliance certifications.

MAX323EPA+ serves as a secondary alternative where bulk packaging is acceptable. This part shares identical electrical characteristics with MAX323CPA+ but carries obsolete product status, limiting its suitability for new designs or long-term procurement strategies.

For applications with strict temperature range requirements below 0°C or above 70°C, the ISL84541IP's extended operating range (-40°C to 85°C) cannot be matched by the MAX323CPA+. In such cases, alternative component families should be evaluated.

Frequently Asked Questions (FAQ)

Q: Can MAX323CPA+ directly replace ISL84541IP in existing PCB designs?

A: Yes. Both components share identical 8-DIP through-hole packaging, pinout compatibility, and core electrical specifications (SPST-NO topology, 2 circuits, 60Ohm on-state resistance, 100pA leakage). No PCB modifications are required.

Q: What are the key electrical differences between ISL84541IP and MAX323CPA+?

A: The MAX323CPA+ operates across a wider supply voltage range (2.7V to 16V vs. 2.7V to 12V). Switch timing is slightly slower (150ns/100ns vs. 100ns/75ns). Channel capacitance is marginally higher (9pF vs. 8pF), and crosstalk is -85dB versus -90dB. These differences are minor and do not affect functionality in standard analog switching applications.

Q: Why is MAX323CPA+ preferred over MAX323EPA+?

A: MAX323CPA+ maintains active product status, ensuring ongoing availability and supply chain stability. MAX323EPA+ is obsolete, presenting long-term procurement risk similar to the original ISL84541IP.

Q: Does operating temperature range affect substitution suitability?

A: The MAX323CPA+ operates from 0°C to 70°C, which is narrower than the ISL84541IP range (-40°C to 85°C). Applications requiring operation below 0°C or above 70°C cannot use MAX323CPA+ as a direct substitute.

Q: Are there compliance or regulatory considerations for substitution?

A: MAX323CPA+ is ROHS3 compliant, whereas ISL84541IP is RoHS non-compliant. For applications subject to RoHS regulations, MAX323CPA+ provides regulatory alignment. Both parts are REACH Unaffected and carry EAR99 ECCN classification.

Q: What packaging options are available for substitute parts?

A: MAX323CPA+ is supplied in Tube packaging, while MAX323EPA+ is supplied in Bulk packaging. Both maintain the 8-DIP through-hole form factor required for PCB compatibility.
