EM513-AP Equivalent & Substitute Parts

Part Overview

The EM513-AP is a general-purpose rectifier diode rated for 1600 V DC reverse voltage with 1 A average rectified current in a through-hole DO-41 package. Manufactured by Micro Commercial Co, this component is classified as obsolete. Due to its obsolete status, identifying equivalent and substitute parts is necessary to maintain design continuity and ensure component availability for production and repair applications. Substitute parts must maintain electrical and mechanical compatibility while meeting the same performance specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the EM513-AP are identified based on strict electrical and mechanical parameter matching. The substitution criteria are:

Primary Matching Parameters:

• Voltage - DC Reverse (Vr) (Max): 1600 V
• Current - Average Rectified (Io): 1 A
• Mounting Type: Through Hole
• Package / Case: DO-41 or DO-204AL (equivalent axial packages)
• Operating Temperature Range: -65°C to 150°C
• Technology: Standard Recovery

Secondary Compliance Parameters:

• RoHS3 Compliance
• Moisture Sensitivity Level (MSL): 1

Parts meeting all primary parameters are classified as direct substitutes. The EM513-AP has two identified substitutes: EM513GP-AP (direct manufacturer equivalent with different packaging) and GP10Y-E3/53 (parametric equivalent from Vishay General Semiconductor).

Parameter Comparison

Engineering Selection Recommendations

EM513GP-AP is the primary substitute for EM513-AP. Both parts are manufactured by Micro Commercial Co and share the same base product number (EM513). The EM513GP-AP is currently in active production status, ensuring long-term availability. The primary difference is packaging format (Tape & Box versus standard packaging) and a slightly elevated forward voltage specification (1.25 V versus 1.1 V at 1 A). Both parts maintain identical reverse voltage, current rating, leakage characteristics, and temperature range. ROHS3 compliance and MSL rating are equivalent.

GP10Y-E3/53 is a parametric equivalent from Vishay General Semiconductor. This part meets all primary electrical specifications and maintains the same voltage, current, and temperature ratings. The forward voltage matches the EM513-AP specification (1.1 V at 1 A). The capacitance specification is lower (5 pF versus 15 pF), which may be advantageous in certain circuit applications. This part is in active production and carries ROHS3 compliance with REACH Unaffected status.

Selection between EM513GP-AP and GP10Y-E3/53 depends on supply chain requirements, preferred manufacturer qualification, and specific circuit performance needs. Both parts are electrically and mechanically compatible with the EM513-AP in standard rectification applications.

Frequently Asked Questions (FAQ)

Q: Can EM513GP-AP be used as a direct replacement for EM513-AP?

A: Yes. Both parts share identical electrical specifications for reverse voltage (1600 V), average rectified current (1 A), reverse leakage (5 µA @ 1600 V), and operating temperature range (-65°C to 150°C). The primary difference is packaging format. EM513GP-AP is supplied in Tape & Box format, while EM513-AP uses standard packaging. Both are through-hole DO-41 components with equivalent mechanical compatibility.

Q: What is the difference in forward voltage between EM513-AP and EM513GP-AP?

A: EM513-AP specifies a maximum forward voltage of 1.1 V at 1 A, while EM513GP-AP specifies 1.25 V at 1 A. This 0.15 V difference is within typical manufacturing tolerance ranges for general-purpose rectifier diodes and does not affect functional compatibility in standard rectification circuits.

Q: Is GP10Y-E3/53 from Vishay compatible with EM513-AP?

A: Yes. GP10Y-E3/53 meets all primary electrical parameters: 1600 V reverse voltage, 1 A average rectified current, 5 µA reverse leakage at 1600 V, and -65°C to 150°C operating temperature. The forward voltage specification (1.1 V at 1 A) matches EM513-AP. The capacitance is lower (5 pF versus 15 pF), which may provide performance benefits in high-frequency applications.

Q: Are all three parts RoHS compliant?

A: Yes. EM513-AP, EM513GP-AP, and GP10Y-E3/53 are all ROHS3 compliant with MSL rating of 1 (Unlimited moisture sensitivity).

Q: Why is EM513-AP listed as obsolete?

A: EM513-AP is classified as obsolete by the manufacturer. Active substitutes (EM513GP-AP and GP10Y-E3/53) are available to support continued design implementation and component procurement.

Q: Can these diodes be used interchangeably in PCB designs?

A: Yes, for through-hole PCB designs. All three parts use DO-41 axial package configuration with identical pin spacing and mechanical dimensions. No PCB layout modifications are required when substituting between these parts.

Q: What is the difference in capacitance between GP10Y-E3/53 and the other parts?

A: GP10Y-E3/53 specifies 5 pF at 4V and 1 MHz, while both EM513-AP and EM513GP-AP specify 15 pF at the same conditions. The lower capacitance of GP10Y-E3/53 may reduce parasitic effects in high-frequency or high-impedance circuits.
