IH5145CPE Equivalent & Substitute Parts

Part Overview

The IH5145CPE is a dual DPST (Double Pole Single Throw) IC switch manufactured by Analog Devices Inc./Maxim Integrated, designed for 2:1 multiplexing applications with 100Ohm on-state resistance. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and procurement planning. The part operates across a dual supply voltage range of ±4.5V to ±18V and is packaged in a 16-pin DIP configuration suitable for through-hole mounting.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the IH5145CPE is determined by strict equivalence across the following critical parameters:

Switch circuit topology (DPST - NO configuration), multiplexer ratio (2:1), number of circuits (2), on-state resistance specification (100Ohm maximum), channel-to-channel matching tolerance (5Ohm), dual supply voltage range (±4.5V ~ 18V), switching time characteristics (300ns Ton, 150ns Toff maximum), charge injection (15pC), leakage current specification (100nA maximum), and package form factor (16-DIP through-hole).

The IH5145CPE+ qualifies as a direct substitute based on identical electrical specifications and compatible packaging. The primary distinction is RoHS compliance status: the IH5145CPE+ achieves ROHS3 compliance, whereas the original IH5145CPE does not. Both parts share the same base product number (IH5145), confirming functional equivalence.

Parameter Comparison

Engineering Selection Recommendations

The IH5145CPE+ is the direct equivalent substitute for the IH5145CPE. Both parts are classified as obsolete and share identical electrical and mechanical specifications. Selection between these parts should be based on regulatory compliance requirements:

For applications subject to RoHS3 compliance mandates, the IH5145CPE+ is the appropriate choice. For legacy systems or applications without RoHS compliance requirements, either part is functionally equivalent. Both parts maintain REACH Unaffected status and identical export classification (EAR99), ensuring consistent regulatory treatment across procurement channels.

Frequently Asked Questions (FAQ)

Q: Can the IH5145CPE+ be used as a direct replacement for the IH5145CPE in existing designs?

A: Yes. The IH5145CPE+ is electrically and mechanically identical to the IH5145CPE. Both parts feature the same 2:1 DPST switch configuration, 100Ohm on-state resistance, dual supply voltage range (±4.5V ~ 18V), switching characteristics, and 16-DIP through-hole package. No circuit modifications are required.

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

A: The IH5145CPE+ achieves ROHS3 compliance, while the IH5145CPE does not. All electrical specifications and package form factors are identical.

Q: Are both parts still available for procurement?

A: Both parts are classified as obsolete. Availability should be confirmed with authorized distributors or component suppliers prior to procurement planning.

Q: Does the RoHS compliance difference affect circuit performance?

A: No. RoHS compliance relates to material composition and environmental standards, not electrical performance. Both parts deliver identical switching characteristics, impedance, and signal integrity.

Q: Can these parts be used in surface-mount applications?

A: No. Both the IH5145CPE and IH5145CPE+ are packaged exclusively in 16-DIP through-hole configuration. Surface-mount alternatives would require a different part number and package designation.

Q: What are the critical parameters for substitution eligibility?

A: Substitution requires equivalence in switch circuit type (DPST - NO), multiplexer configuration (2:1), number of circuits (2), on-state resistance (100Ohm maximum), channel matching tolerance (5Ohm), dual supply voltage range (±4.5V ~ 18V), switching time specifications (300ns Ton, 150ns Toff), charge injection (15pC), leakage current (100nA maximum), and 16-DIP through-hole package form factor.
