Engineering Selection Recommendations

The MAX4614CPD+ is the direct equivalent substitute for the MAX4614CPD. Both components share identical electrical specifications and package configurations, ensuring functional interchangeability in circuit applications.

The primary distinction between these parts is product lifecycle status and regulatory compliance:

MAX4614CPD: Classified as obsolete with RoHS non-compliant status. This part number should be reserved for legacy system maintenance and repair applications where original component specifications are mandatory.
MAX4614CPD+: Designated as active product status with ROHS3 compliance certification. This variant is the appropriate selection for new designs, production continuations, and systems requiring current regulatory compliance. The active status ensures ongoing manufacturer support and availability.

Both components maintain identical electrical performance characteristics, including on-state resistance, switching speed, bandwidth, and signal integrity parameters. The 14-DIP through-hole package format is consistent across both variants, permitting direct PCB-level substitution without layout modifications.

Frequently Asked Questions (FAQ)

Q: Can MAX4614CPD+ be used as a direct replacement for MAX4614CPD in existing designs?

A: Yes. The MAX4614CPD+ provides complete electrical and mechanical equivalence to the MAX4614CPD. All performance parameters, including on-state resistance (10Ohm), switching times (12ns/10ns), bandwidth (70MHz), and package dimensions (14-DIP, 0.300" pitch) are identical. Direct PCB substitution is possible without circuit modifications.

Q: What is the difference between MAX4614CPD and MAX4614CPD+?

A: The primary differences are product status and regulatory compliance. The MAX4614CPD is obsolete and RoHS non-compliant, while the MAX4614CPD+ is an active product with ROHS3 compliance. Electrical specifications and package format are identical.

Q: Why should new designs use MAX4614CPD+ instead of MAX4614CPD?

A: The MAX4614CPD+ carries active product status, ensuring manufacturer support, ongoing availability, and compliance with current regulatory requirements (ROHS3). The MAX4614CPD is obsolete and may face supply constraints. For new product development, MAX4614CPD+ is the recommended selection.

Q: Are there any package or pinout differences between these parts?

A: No. Both components use the 14-DIP package with 0.300" (7.62mm) pitch and through-hole mounting. Pinout and physical dimensions are identical, permitting direct substitution on existing PCBs.

Q: What are the critical parameters that define substitution eligibility for this switch IC?

A: Substitution eligibility is determined by: SPST-NO switch circuit configuration, 4-circuit count, 1:1 multiplexer topology, 10Ohm maximum on-state resistance, 200mOhm channel matching, 2V-5.5V supply voltage range, 12ns/10ns switching times, 70MHz bandwidth, and 14-DIP through-hole package format. All parameters must match or exceed the original specification.

Q: Can MAX4614CPD be used in applications requiring RoHS compliance?

A: No. The MAX4614CPD is RoHS non-compliant. For applications requiring RoHS compliance certification, the MAX4614CPD+ (ROHS3 compliant) must be used.
