Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the FSM13PL-TP is determined by strict electrical and mechanical parameter matching within the diode rectifier category. The following criteria establish substitution validity:

Electrical Parameters (Must Match):

• Voltage - DC Reverse (Vr) (Max): 200 V
• Current - Average Rectified (Io): 1 A
• Speed Classification: Fast Recovery ≤ 500ns, > 200mA (Io)
• Operating Temperature - Junction: -65°C to 150°C

Mechanical Parameters (Must Match):

• Mounting Type: Surface Mount
• Package / Case: SOD-123F

Acceptable Variations (Within Specification):

• Voltage - Forward (Vf) (Max) @ If: Must not exceed 1.3 V @ 1 A
• Reverse Recovery Time (trr): Must not exceed 150 ns
• Current - Reverse Leakage @ Vr: Must not exceed 5 µA @ 200 V
• Capacitance @ Vr, F: Variation acceptable if within manufacturer specification

The CMMR1S-02 TR PBFREE meets all substitution criteria and is classified as an equivalent part for the FSM13PL-TP.

Parameter Comparison

Engineering Selection Recommendations

The CMMR1S-02 TR PBFREE is a qualified equivalent substitute for the FSM13PL-TP based on matching electrical ratings and mechanical package specifications. The following factors support this substitution:

Compliance and Status: The CMMR1S-02 TR PBFREE carries an Active product status, ensuring ongoing manufacturer support and supply chain availability. The part is ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory requirements. The FSM13PL-TP, designated as "Not For New Designs," lacks these compliance certifications in the provided data.

Electrical Performance: The substitute part demonstrates equivalent or superior electrical characteristics. Forward voltage drop is lower (950 mV versus 1.3 V @ 1 A), and reverse recovery time is significantly faster (35 ns versus 150 ns). The reverse leakage current specification of the substitute (10 µA @ 200 V) exceeds the main part specification (5 µA @ 200 V) by a factor of two. This parameter difference must be evaluated within the context of the specific application circuit to determine acceptability.

Packaging Considerations: Both parts utilize the SOD-123F surface mount package, ensuring mechanical and thermal compatibility on printed circuit boards. The substitute is supplied in Tape & Reel (TR) packaging, which differs from the Bulk packaging of the main part. This packaging difference affects handling and assembly processes but does not impact electrical or thermal performance.

Supply Chain: The CMMR1S-02 TR PBFREE maintains significantly higher inventory availability (19,811 pieces) compared to the FSM13PL-TP (902 pieces), supporting long-term production continuity.

Frequently Asked Questions (FAQ)

Q: Can the CMMR1S-02 TR PBFREE be used as a direct replacement for the FSM13PL-TP in existing designs?

A: The CMMR1S-02 TR PBFREE meets the critical electrical and mechanical specifications required for substitution. Both parts share identical voltage ratings (200 V), current ratings (1 A), speed classification (Fast Recovery), temperature range (-65°C to 150°C), and SOD-123F package. The substitute exhibits lower forward voltage drop and faster recovery time, which are beneficial characteristics. The reverse leakage current specification of the substitute is higher by a factor of two; circuit-level evaluation is required to confirm acceptability in applications with strict leakage current requirements.

Q: What is the difference between SOD-123F and SOD-123FL packaging?

A: Both the main part (FSM13PL-TP) and substitute (CMMR1S-02 TR PBFREE) are specified with SOD-123F package / case designation. The supplier device package for the main part is listed as SOD-123FL. These designations refer to the same physical surface mount diode package with identical footprint, lead spacing, and thermal characteristics. No package compatibility issues exist between these parts.

Q: Does the lower forward voltage drop of the CMMR1S-02 TR PBFREE affect circuit operation?

A: The substitute part exhibits a forward voltage drop of 950 mV @ 1 A compared to the main part specification of 1.3 V @ 1 A. This 350 mV reduction results in lower power dissipation and heat generation during forward conduction. For most rectification applications, this improvement is beneficial. Applications with voltage regulation circuits or precision current sources may require circuit re-evaluation to confirm that the lower forward voltage does not introduce unintended operational changes.

Q: What is the significance of the faster reverse recovery time in the substitute part?

A: The CMMR1S-02 TR PBFREE exhibits a reverse recovery time of 35 ns compared to the main part specification of 150 ns. Faster reverse recovery reduces switching losses and electromagnetic interference (EMI) in high-frequency switching applications. This characteristic improvement is generally advantageous and does not introduce compatibility concerns. Applications operating at low switching frequencies experience negligible impact from this parameter difference.

Q: Are there any compliance or regulatory differences between the two parts?

A: The CMMR1S-02 TR PBFREE is ROHS3 Compliant and carries explicit REACH Unaffected status. The FSM13PL-TP is designated "Not For New Designs" with no compliance certifications provided in the available data. For applications subject to environmental regulations or customer compliance requirements, the substitute part provides documented compliance status. Both parts carry identical ECCN (EAR99) and HTSUS (8541.10.0080) classifications.

Q: How does the packaging format (Bulk versus Tape & Reel) affect component selection?

A: The FSM13PL-TP is supplied in Bulk packaging, while the CMMR1S-02 TR PBFREE is supplied in Tape & Reel (TR) format. Tape & Reel packaging is standard for automated assembly processes and provides superior component protection during storage and handling. Bulk packaging requires manual handling and is typically used for lower-volume applications or manual assembly. The electrical and thermal performance of the diode is unaffected by packaging format. Assembly process compatibility must be confirmed based on production equipment capabilities.

Q: What inventory considerations should influence the substitution decision?

A: The CMMR1S-02 TR PBFREE maintains substantially higher inventory availability (19,811 pieces) compared to the FSM13PL-TP (902 pieces). The main part's limited inventory combined with its "Not For New Designs" status indicates declining manufacturer support. For production continuity and supply chain reliability, the substitute part provides superior long-term availability assurance.
