MAX214EPI Equivalent & Substitute Parts

Part Overview

The MAX214EPI is a full-duplex RS232 transceiver manufactured by Analog Devices Inc./Maxim Integrated, featuring 3 drivers and 5 receivers in a 28-pin DIP package. This component is classified as obsolete, making identification of compatible substitute parts essential for system maintenance, repair, and legacy design support. The transceiver operates across the 4.5V to 5.5V supply range with a maximum data rate of 116 Kbps and is rated for industrial temperature environments from -40°C to 85°C.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MAX214EPI is determined by strict equivalence across the following critical parameters:

• Protocol Compatibility: RS232 full-duplex transceiver architecture
• Driver/Receiver Configuration: 3 drivers and 5 receivers
• Electrical Performance: 116 Kbps data rate, 500 mV receiver hysteresis
• Supply Voltage Range: 4.5V ~ 5.5V operation
• Temperature Rating: -40°C to 85°C operating range
• Package Specification: 28-pin DIP form factor with identical pinout
• Mounting Technology: Through-hole PCB assembly compatibility

The MAX214EPI+ qualifies as a direct substitute based on identical electrical specifications, configuration, and physical packaging. Differences in product status and compliance certifications do not affect functional interchangeability in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

The MAX214EPI+ provides functional equivalence to the MAX214EPI across all electrical and mechanical parameters. Selection between these parts should be based on:

Compliance Requirements: The MAX214EPI+ carries ROHS3 compliance certification, whereas the MAX214EPI is RoHS non-compliant. Applications subject to RoHS regulatory requirements must use the MAX214EPI+.

Packaging Considerations: The MAX214EPI+ is supplied in tube packaging, while the MAX214EPI uses standard packaging. Tube packaging may affect handling procedures and inventory management in production environments.

Availability: Both parts are classified as obsolete. Current inventory levels should be verified with the supplier before design commitment or procurement planning.

Regulatory Status: Both parts maintain identical REACH and ECCN classifications (REACH Unaffected, EAR99), indicating no additional regulatory constraints on substitution.

Frequently Asked Questions (FAQ)

Q: Can MAX214EPI+ be used as a direct replacement for MAX214EPI in existing designs?

A: Yes. The MAX214EPI+ is electrically and mechanically equivalent. All functional parameters—protocol, driver/receiver configuration, data rate, supply voltage, temperature range, and package pinout—are identical. Substitution requires no circuit modifications.

Q: What is the difference between MAX214EPI and MAX214EPI+?

A: The primary differences are RoHS compliance status (MAX214EPI+ is ROHS3 compliant; MAX214EPI is non-compliant) and packaging format (MAX214EPI+ uses tube packaging). Electrical performance and pinout are identical.

Q: Are there any compatibility issues with the 28-DIP package?

A: No. Both parts use the same 28-pin DIP package with 0.600" (15.24mm) body width. PCB footprints, through-hole spacing, and mounting procedures are identical.

Q: Why is the MAX214EPI classified as obsolete?

A: Obsolete status indicates the part is no longer in active production. Existing inventory may be available through authorized distributors, but long-term availability cannot be guaranteed.

Q: Should I select MAX214EPI+ over MAX214EPI for new designs?

A: Selection should be based on regulatory requirements. If RoHS3 compliance is mandatory, MAX214EPI+ is the appropriate choice. Both parts are obsolete; availability should be confirmed before design commitment.

Q: What parameters determine substitution eligibility for RS232 transceivers?

A: Critical parameters include protocol (RS232), driver/receiver count (3/5), duplex mode (full), data rate (116 Kbps), supply voltage range (4.5V–5.5V), operating temperature (-40°C to 85°C), and package type (28-DIP). All must match for direct substitution.
