Substitute Part Grouping Explanation

Substitution eligibility for the IH5142CPE+ is determined by strict equivalence across the following critical parameters:

Switch circuit configuration (SPDT topology)
Multiplexer ratio (2:1 channel configuration)
Single circuit count
On-state resistance specification (100Ohm maximum)
Channel matching tolerance (5Ohm maximum)
Dual supply voltage range (±4.5V ~ 18V)
Switch timing performance (Ton ≤ 300ns, Toff ≤ 150ns)
Charge injection specification (15pC)
Leakage current rating (100nA maximum)
Operating temperature range (0°C ~ 70°C)

Engineering Selection Recommendations

The IH5142CPE+ maintains Active product status with full RoHS3 compliance and REACH unaffected classification, confirming ongoing manufacturing support and regulatory alignment for new designs. The part carries ECCN EAR99 classification and HTSUS code 8542.39.0001, establishing its export and tariff status for procurement planning.

Selection of equivalent parts must prioritize matching all specified electrical parameters without deviation. The 100Ohm on-state resistance, 5Ohm channel matching tolerance, and ±4.5V ~ 18V dual supply range define the functional envelope for this switch topology. Switch timing specifications (300ns turn-on, 150ns turn-off) and 15pC charge injection are critical for signal integrity in multiplexing applications.

The 16-DIP through-hole package format is mandatory for board-level compatibility. Substitutes must maintain identical pin configuration and mechanical footprint. MSL 1 (Unlimited) moisture sensitivity rating permits standard handling and storage without special precautions.

Frequently Asked Questions (FAQ)

Q: What defines an acceptable substitute for the IH5142CPE+?

A: An acceptable substitute must match all electrical specifications including SPDT switch topology, 2:1 multiplexer configuration, 100Ohm on-state resistance, 5Ohm channel matching, ±4.5V ~ 18V supply voltage, 300ns/150ns switch timing, 15pC charge injection, and 100nA leakage current. The part must be packaged in 16-DIP through-hole format with Active product status and RoHS3 compliance.

Q: Can parts with different on-state resistance values substitute for the IH5142CPE+?

A: No. The 100Ohm on-state resistance specification is a core functional parameter. Parts with different resistance values will alter signal attenuation and impedance matching characteristics in the circuit and are not acceptable substitutes.

Q: Are there compatibility considerations for the 16-DIP through-hole package?

A: Yes. The 16-DIP package with 0.300" (7.62mm) body width is specific to this device. PCB footprint, pin spacing, and insertion hole diameter must match exactly. Surface-mount alternatives or different DIP body widths are not compatible without board redesign.

Q: Does the ±4.5V ~ 18V dual supply voltage range affect substitution?

A: Yes. The specified supply voltage range is a critical operating parameter. Substitutes must support the identical voltage range. Parts with different supply specifications will not function correctly in circuits designed for ±4.5V ~ 18V operation.

Q: What is the significance of the 5Ohm channel-to-channel matching specification?

A: Channel-to-channel matching (ΔRon) of 5Ohm maximum ensures consistent signal attenuation across both switch channels. This parameter is essential for applications requiring balanced switching performance. Substitutes must meet or exceed this matching tolerance.

Q: Is RoHS3 compliance mandatory for substitution?

A: Yes. The IH5142CPE+ is RoHS3 compliant. Substitutes must maintain equivalent compliance status to ensure regulatory alignment and material composition consistency in production environments.

Q: Can the IH5142CPE+ be substituted with a different switch topology (e.g., SPST or DPDT)?

A: No. The SPDT (Single Pole Double Throw) topology with 2:1 multiplexer configuration is specific to this device function. Different switch topologies have different pin configurations and functional behavior and are not compatible substitutes.
