EM513-TP Equivalent & Substitute Parts

Part Overview

The EM513-TP is a general-purpose rectifier diode rated for 1600 V DC reverse voltage and 1 A average rectified current in a DO-41 axial through-hole package. This component is classified as obsolete, indicating that the original part is no longer in active production. Locating equivalent substitute parts is necessary to maintain design continuity, support ongoing repairs, and ensure component availability for legacy systems and applications currently utilizing this diode specification.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the EM513-TP is determined by electrical and mechanical parameter equivalence. The critical parameters that define substitutability are:

• Voltage Rating: DC reverse voltage must equal or exceed 1600 V
• Current Rating: Average rectified current must equal or exceed 1 A
• Package Type: Must be DO-41 axial through-hole configuration
• Mounting: Through-hole mounting compatibility
• Recovery Speed: Standard recovery characteristics >500ns at >200mA
• Temperature Range: Operating junction temperature range of -65°C to 150°C
• Reverse Leakage: Maximum 5 µA at 1600 V

The EM513GP-TP qualifies as a direct substitute based on matching all electrical ratings, package specifications, and thermal operating range. The primary distinction is product status: EM513GP-TP is active production, whereas EM513-TP is obsolete.

Parameter Comparison

Engineering Selection Recommendations

The EM513GP-TP is the direct equivalent substitute for the obsolete EM513-TP. Both components are manufactured by Micro Commercial Co and share identical electrical specifications, thermal ratings, and package configurations.

Compliance Status: Both parts maintain ROHS3 compliance and MSL Level 1 (unlimited moisture sensitivity), ensuring regulatory alignment for applications requiring environmental compliance certification.

Product Status Consideration: The EM513GP-TP is in active production status, providing assured long-term availability and supply chain continuity compared to the obsolete EM513-TP. This status change is the primary driver for substitution in new procurement and legacy system support.

Packaging Difference: The EM513-TP is supplied in bulk packaging, while EM513GP-TP is supplied in Tape & Reel (TR) format. This packaging distinction does not affect electrical or mechanical compatibility; it reflects manufacturing and distribution methodology.

Forward Voltage Variance: The EM513GP-TP exhibits a maximum forward voltage of 1.25 V at 1 A compared to 1.1 V for the EM513-TP. This 0.15 V difference remains within acceptable tolerance for standard rectifier applications and does not compromise circuit performance in typical general-purpose rectification circuits.

Frequently Asked Questions (FAQ)

Q: Can EM513GP-TP directly replace EM513-TP in existing circuit designs?

A: Yes. The EM513GP-TP is electrically and mechanically equivalent to the EM513-TP. Both components share identical voltage ratings (1600 V), current ratings (1 A), package type (DO-41 axial), and operating temperature range (-65°C to 150°C). Direct substitution is supported without circuit modification.

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

A: The EM513GP-TP has a maximum forward voltage of 1.25 V at 1 A, compared to 1.1 V for the EM513-TP. This 0.15 V difference is typical manufacturing variation within the standard rectifier diode category and does not affect circuit functionality in general-purpose rectification applications. Circuit designs accommodating standard rectifier forward voltage tolerances will operate without issue.

Q: Why is EM513-TP listed as obsolete?

A: The EM513-TP is no longer in active production. The EM513GP-TP represents the current production equivalent, ensuring ongoing availability and supply chain support for applications requiring this diode specification.

Q: Does the Tape & Reel packaging of EM513GP-TP affect compatibility?

A: No. Tape & Reel packaging is a distribution format used for automated assembly processes. The individual diode component, its electrical characteristics, and physical dimensions remain identical to bulk-packaged versions. The DO-41 axial package configuration is unchanged.

Q: Are both parts RoHS compliant?

A: Yes. Both EM513-TP and EM513GP-TP are ROHS3 compliant and carry MSL Level 1 (unlimited) moisture sensitivity rating, meeting environmental and regulatory requirements for industrial and commercial applications.

Q: What are the critical parameters for confirming substitutability?

A: Substitutability is confirmed by matching: (1) DC reverse voltage rating (1600 V), (2) average rectified current rating (1 A), (3) package type (DO-41 axial through-hole), (4) operating temperature range (-65°C to 150°C), and (5) recovery speed characteristics (standard >500ns). All parameters are identical between EM513-TP and EM513GP-TP.
