HIN241CAZ Equivalent & Substitute Parts

Part Overview

The HIN241CAZ is a 4/5 full-duplex RS232 transceiver manufactured by Renesas Electronics Corporation in a 28-SSOP surface mount package. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing system support and new design implementations. The HIN241CAZ operates within a 4.5V to 5.5V supply range with a 120 kbps data rate and 500 mV receiver hysteresis, suitable for legacy RS232 communication applications requiring full transceiver functionality.

Duplex: Full
Data Rate: 120 kbps
Package / Case: 28-SSOP (0.209", 5.30mm Width)
Mounting Type: Surface Mount
RoHS Status: ROHS3 Compliant

Substitute parts are grouped into three categories based on additional parameter alignment:

Parametric Equivalent: HIN213ECAZ matches all critical parameters with identical supply voltage range (4.5V ~ 5.5V) and receiver hysteresis (500 mV). Product status is Active, providing improved availability.

Upgrade Category: MAX241EAI+ maintains all critical parameters while offering extended operating temperature range (-40°C ~ 85°C versus 0°C ~ 70°C) and improved moisture sensitivity level (MSL 1 versus MSL 3). Supply voltage and receiver hysteresis remain identical.

Similar Category: ADM241LARSZ, ADM241LARSZ-REEL, ADM241LJRSZ, ADM241LJRSZ-REEL, MAX211ECAI+T, MAX211EEAI+, MAX211EEAI+T, and MAX211IDB maintain all critical parameters with variations in receiver hysteresis (650 mV for ADM241 variants), supply voltage range (4.75V ~ 5.25V for ADM241 variants), operating temperature, and moisture sensitivity level. These parts are functionally compatible for RS232 transceiver applications within their specified operating conditions.

Engineering Selection Recommendations

For direct replacement of the obsolete HIN241CAZ in existing designs operating within 0°C to 70°C temperature range, HIN213ECAZ from Renesas Electronics Corporation provides parametric equivalence with Active product status and identical electrical specifications. This option maintains supply voltage range, receiver hysteresis, and operating temperature parameters while improving component availability.

For new designs or systems requiring extended operating temperature capability, MAX241EAI+ from Analog Devices Inc./Maxim Integrated offers superior performance with -40°C to 85°C operating range, improved moisture sensitivity level (MSL 1), and identical receiver hysteresis and supply voltage specifications. This part is ROHS3 compliant and carries Active product status.

For applications where receiver hysteresis of 650 mV is acceptable and supply voltage range of 4.75V to 5.25V is compatible with system design, ADM241LARSZ and ADM241LJRSZ variants from Analog Devices Inc. provide Active product status with MSL 1 rating and extended temperature ranges. ADM241LARSZ supports -40°C to 85°C operation, while ADM241LJRSZ maintains 0°C to 70°C operation matching the original part's temperature range.

MAX211 series parts (MAX211ECAI+T, MAX211EEAI+, MAX211EEAI+T) from Analog Devices Inc./Maxim Integrated maintain identical receiver hysteresis and supply voltage to the HIN241CAZ with improved MSL 1 rating and Active product status. MAX211EEAI+ and MAX211EEAI+T offer extended temperature range to -40°C to 85°C.

All recommended substitutes maintain ROHS3 compliance and are suitable for surface mount assembly in 28-SSOP packages.

Frequently Asked Questions (FAQ)

Q: Can HIN213ECAZ directly replace HIN241CAZ without design modifications?

A: Yes. HIN213ECAZ is a parametric equivalent with identical supply voltage (4.5V ~ 5.5V), receiver hysteresis (500 mV), operating temperature range (0°C ~ 70°C), and 28-SSOP package. The primary difference is improved product status from Obsolete to Active.

Q: What is the difference between ADM241LARSZ and ADM241LJRSZ?

A: Both parts are from Analog Devices Inc. with identical electrical specifications. The primary difference is operating temperature range: ADM241LARSZ operates from -40°C to 85°C, while ADM241LJRSZ operates from 0°C to 70°C. ADM241LARSZ-REEL and ADM241LJRSZ-REEL are tape and reel packaging variants of these parts.

Q: Why do some substitutes have 650 mV receiver hysteresis instead of 500 mV?

A: ADM241 variants from Analog Devices Inc. feature 650 mV receiver hysteresis compared to the HIN241CAZ specification of 500 mV. This higher hysteresis value remains within RS232 protocol specifications and is functionally compatible for standard RS232 communication applications. System design must confirm this parameter is acceptable for the intended application.

Q: What does MSL rating mean and why does it differ between parts?

A: Moisture Sensitivity Level (MSL) indicates the component's sensitivity to moisture during storage and handling. HIN241CAZ has MSL 3 (168 hours), while most active substitutes have MSL 1 (unlimited). Lower MSL ratings provide greater flexibility in storage and handling conditions without requiring special moisture control measures.

Q: Are MAX211 series parts suitable replacements for HIN241CAZ?

A: Yes. MAX211ECAI+T, MAX211EEAI+, and MAX211EEAI+T maintain identical receiver hysteresis (500 mV) and supply voltage range (4.5V ~ 5.5V) to HIN241CAZ. All feature improved MSL 1 rating and Active product status. MAX211EEAI+ and MAX211EEAI+T offer extended operating temperature to -40°C ~ 85°C.

Q: What packaging options are available for substitute parts?

A: Substitute parts are available in multiple packaging formats: Tube, Tape & Reel (TR), and Cut Tape (CT) & Digi-Reel. Selection depends on assembly requirements and procurement volume. All maintain the 28-SSOP (0.209", 5.30mm Width) physical package specification.

Q: Is MAX211IDB a suitable replacement despite being obsolete?

A: MAX211IDB is classified as Obsolete and should not be selected for new designs or long-term supply requirements. While it maintains identical electrical specifications to HIN241CAZ, its obsolete status creates the same supply risk as the original part. Active alternatives such as MAX211EEAI+ or MAX241EAI+ are recommended.
