OPA241PAG4 Equivalent & Substitute Parts

Part Overview

The OPA241PAG4 is a general-purpose operational amplifier manufactured by Texas Instruments, featuring rail-to-rail output capability in an 8-PDIP through-hole package. This device is designed for low-power applications requiring single-supply operation across a wide voltage range of 2.7 V to 36 V. The OPA241PAG4 is currently discontinued at DiGi Electronics, necessitating identification of functionally equivalent substitute components for ongoing design support and procurement.

Parameter Comparison

Engineering Selection Recommendations

The OPA241PA is a direct functional equivalent to the OPA241PAG4 and is suitable for substitution in applications where the OPA241PAG4 is no longer available. Both devices share identical electrical specifications, package configuration, and regulatory compliance status.

Product Status Consideration: The OPA241PAG4 is discontinued at DiGi Electronics. The OPA241PA carries a Last Time Buy status, indicating limited future availability. For long-term procurement planning, alternative sourcing strategies should be evaluated.

Compliance Status: Both the OPA241PAG4 and OPA241PA maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory compatibility in applications subject to these requirements.

Packaging Difference: The OPA241PAG4 is supplied in standard packaging, while the OPA241PA is supplied in tube packaging. This difference does not affect electrical performance or mechanical compatibility in through-hole PCB applications.

Frequently Asked Questions (FAQ)

Q: Can the OPA241PA be used as a direct replacement for the OPA241PAG4?

A: Yes. The OPA241PA meets all electrical performance specifications and mechanical compatibility requirements of the OPA241PAG4. Both devices feature identical amplifier type, output characteristics, frequency response, and supply voltage range.

Q: What is the difference between OPA241PAG4 and OPA241PA?

A: The primary difference is packaging format. The OPA241PAG4 uses standard packaging, while the OPA241PA uses tube packaging. Electrically and mechanically, both devices are equivalent for through-hole PCB applications.

Q: Are there any compliance concerns when substituting OPA241PA for OPA241PAG4?

A: No. Both devices maintain ROHS3 compliance and REACH unaffected status. Regulatory requirements are satisfied by either component.

Q: What is the significance of the Last Time Buy status for OPA241PA?

A: Last Time Buy status indicates that the manufacturer has announced end-of-life for this product. Existing inventory may be available, but future production is not planned. For applications requiring long-term component availability, alternative solutions should be evaluated.

Q: Are the pin configurations identical between OPA241PAG4 and OPA241PA?

A: Yes. Both devices use the 8-DIP (0.300", 7.62mm) package with identical through-hole pin configuration, enabling direct PCB substitution without layout modifications.

Q: What supply voltage range is supported by the OPA241PA?

A: The OPA241PA supports a supply voltage range of 2.7 V to 36 V, identical to the OPA241PAG4, enabling operation in single-supply or dual-supply configurations across this range.
