The EM516GP-AP is manufactured by Micro Commercial Co and carries an active product status, ensuring long-term availability and supply chain continuity.

Parameter Comparison

Engineering Selection Recommendations

The EM516GP-AP is the direct equivalent substitute for the obsolete EM516-AP. Both parts are manufactured by Micro Commercial Co and share identical electrical and mechanical specifications across all critical parameters. The forward voltage (Vf) of the EM516GP-AP is 1.25 V at 1 A, compared to 1.1 V for the EM516-AP; this variance remains within acceptable tolerance for general-purpose rectifier applications and does not affect functional compatibility.

The EM516GP-AP carries an active product status, ensuring availability for new designs and ongoing production requirements. Both parts maintain ROHS3 compliance and unlimited moisture sensitivity classification (MSL 1), supporting deployment in standard industrial and commercial environments.

The EM516GP-AP is supplied in Tape & Box (TB) packaging, providing standard handling and storage conditions suitable for automated assembly processes and manual component selection.

Frequently Asked Questions (FAQ)

Q: Can the EM516GP-AP be used as a direct replacement for the EM516-AP in existing designs?

A: Yes. The EM516GP-AP is electrically and mechanically equivalent to the EM516-AP across all specified parameters. Both components share identical voltage ratings (1800 V DC reverse), current ratings (1 A average rectified), recovery speed, leakage characteristics, and thermal operating range. The DO-41 axial through-hole package is identical, enabling direct board-level substitution without layout modifications.

Q: What is the difference in forward voltage between these parts?

A: The EM516-AP specifies a maximum forward voltage of 1.1 V at 1 A, while the EM516GP-AP specifies 1.25 V at 1 A. This 0.15 V difference is within normal manufacturing tolerance for general-purpose rectifier diodes and does not affect circuit functionality in standard rectification applications.

Q: Why is the EM516-AP classified as obsolete?

A: The EM516-AP is listed as obsolete, indicating it is no longer in active production. The EM516GP-AP, manufactured by the same supplier, serves as the active equivalent for ongoing procurement and design support.

Q: Are there any compliance or certification differences between these parts?

A: Both parts are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity classification. No compliance or certification differences exist between the two components.

Q: What packaging options are available for the substitute part?

A: The EM516GP-AP is supplied in Tape & Box (TB) packaging, which is standard for through-hole axial components and suitable for both manual and automated assembly processes.

Q: Can these parts be used interchangeably in high-voltage applications?

A: Yes. Both parts are rated for 1800 V DC reverse voltage and maintain identical reverse leakage characteristics (5 µA @ 1800 V). They are suitable for equivalent high-voltage rectification applications within the specified voltage and current ratings.
