CMR1-10M TR13 Equivalent & Substitute Parts

Part Overview

The CMR1-10M TR13 is a general-purpose rectifier diode rated for 1000 V DC reverse voltage and 1 A average rectified current in a surface mount SMA package. This component is classified as Active and employs standard recovery technology. Substitute parts are identified when equivalent electrical performance, mechanical compatibility, and thermal operating range are maintained across the specified parameters. Alternative sources become necessary to address inventory availability, packaging format requirements, or compliance certifications specific to end-application requirements.

Substitute Part Grouping Explanation

Substitute parts for the CMR1-10M TR13 are qualified based on strict equivalence across the following electrical and mechanical parameters:

Qualifying Criteria:

Voltage - DC Reverse (Vr) (Max): 1000 V minimum
Current - Average Rectified (Io): 1 A minimum
Voltage - Forward (Vf) (Max) @ If: 1.1 V or lower @ 1 A
Current - Reverse Leakage @ Vr: 5 µA or lower @ 1000 V
Operating Temperature - Junction: -65°C to 150°C minimum range
Package / Case: DO-214AC, SMA surface mount configuration
Product Status: Active

Parts meeting these criteria are classified as parametric equivalents and are suitable for direct substitution in applications where the CMR1-10M TR13 is specified. Packaging format (Tape & Reel versus Cut Tape) and manufacturer source do not affect electrical or thermal compatibility.

Engineering Selection Recommendations

CMR1-10M TR13 PBFREE (Central Semiconductor Corp)

This part is a direct parametric equivalent to the CMR1-10M TR13 with identical electrical specifications. The PBFREE designation indicates lead-free material composition. This substitute is ROHS3 compliant with MSL rating of 1 (Unlimited), providing enhanced environmental and regulatory compliance. Packaging is supplied in Tape & Reel (TR) format. Selection of this part is appropriate when ROHS3 compliance is required or when Tape & Reel packaging format is preferred for automated assembly operations.

S1M-13-F (Diodes Incorporated)

This part meets all electrical equivalence criteria with identical voltage, current, and thermal specifications. The S1M-13-F is ROHS3 compliant with MSL rating of 1 (Unlimited). Capacitance is specified at 10 pF versus 8 pF for the CMR1-10M TR13, representing a minor variance within acceptable tolerance for general-purpose rectification applications. Packaging is supplied in Cut Tape (CT) & Digi-Reel® format. Selection of this part is appropriate when sourcing from Diodes Incorporated is required or when Cut Tape packaging format is preferred.

Frequently Asked Questions (FAQ)

Q: Can the CMR1-10M TR13 PBFREE be used as a direct replacement for the CMR1-10M TR13?

A: Yes. The CMR1-10M TR13 PBFREE is a parametric equivalent with identical electrical performance across all specified parameters: 1000 V reverse voltage, 1 A average rectified current, 1.1 V forward voltage drop, and -65°C to 150°C operating range. The PBFREE designation refers to material composition and does not affect electrical function.

Q: What is the difference between the CMR1-10M TR13 and the S1M-13-F?

A: Both parts are parametric equivalents with identical voltage, current, and thermal ratings. The primary differences are manufacturer source (Central Semiconductor Corp versus Diodes Incorporated) and capacitance specification (8 pF versus 10 pF at 4V, 1MHz). The 2 pF capacitance variance is not significant for standard rectification applications.

Q: Are packaging format differences between Tape & Reel and Cut Tape significant for substitution?

A: Packaging format affects handling, storage, and assembly process compatibility but does not affect electrical or thermal performance. Selection between Tape & Reel (CMR1-10M TR13 PBFREE) and Cut Tape (S1M-13-F) depends on assembly equipment and process requirements, not component function.

Q: Do all substitute parts meet ROHS3 compliance?

A: The CMR1-10M TR13 PBFREE and S1M-13-F are both ROHS3 compliant. The original CMR1-10M TR13 does not specify ROHS status in the provided data. If ROHS3 compliance is required, use CMR1-10M TR13 PBFREE or S1M-13-F.

Q: Is reverse recovery time a factor in selecting between these parts?

A: Reverse recovery time (trr) is specified only for the S1M-13-F at 3 µs. This parameter is not provided for the CMR1-10M TR13 variants. For applications where reverse recovery time is critical, the S1M-13-F specification of 3 µs is available for design verification.

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

A: Yes. All three parts share identical operating temperature range of -65°C to 150°C junction temperature. Selection between parts is not affected by thermal operating range requirements within this specification.
