Substitute Part Grouping Explanation

Substitution of the FR1A-13-F is determined by electrical and mechanical parameter equivalence. The primary substitution criteria are:

Electrical Parameters (Must Match):

• Voltage - DC Reverse (Vr) (Max): 50 V
• Current - Average Rectified (Io): 1 A
• Voltage - Forward (Vf) (Max) @ If: 1.3 V @ 1 A
• Speed Classification: Fast Recovery ≤ 500 ns, > 200 mA (Io)
• Reverse Recovery Time (trr): 150 ns
• Current - Reverse Leakage @ Vr: 5 µA @ 50 V

Mechanical Parameters (Must Match):

• Package / Case: DO-214AA, SMB
• Mounting Type: Surface Mount

Compliance Parameters (Must Match or Exceed):

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

The RS1AB-13-F meets all electrical and mechanical substitution criteria and maintains equivalent compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The RS1AB-13-F is a direct electrical and mechanical equivalent to the FR1A-13-F. Both components are manufactured by Diodes Incorporated and share identical electrical specifications for voltage, current, forward voltage drop, recovery time, and leakage current characteristics. Both are packaged in the DO-214AA SMB surface mount package and maintain equivalent RoHS3 compliance and MSL ratings.

The primary distinction is product status: the FR1A-13-F is obsolete, while the RS1AB-13-F is active in production. The RS1AB-13-F has a maximum operating junction temperature of 150°C compared to 175°C for the FR1A-13-F. For applications operating within the 150°C maximum junction temperature limit, the RS1AB-13-F provides full functional equivalence with the advantage of active availability and ongoing manufacturer support.

Frequently Asked Questions (FAQ)

Q: Can the RS1AB-13-F be used as a direct replacement for the FR1A-13-F in existing designs?

A: Yes. The RS1AB-13-F meets all electrical and mechanical specifications of the FR1A-13-F. Both components have identical voltage ratings (50 V), current ratings (1 A), forward voltage characteristics (1.3 V @ 1 A), recovery time (150 ns), and package configuration (DO-214AA SMB). No circuit modifications are required for substitution.

Q: What is the difference in operating temperature range between these parts?

A: The FR1A-13-F operates from -65°C to 175°C junction temperature, while the RS1AB-13-F operates from -65°C to 150°C. For applications where the junction temperature remains below 150°C, both parts are functionally equivalent. Applications requiring operation above 150°C junction temperature cannot use the RS1AB-13-F as a substitute.

Q: Are both parts RoHS compliant?

A: Yes. Both the FR1A-13-F and RS1AB-13-F are ROHS3 compliant and carry MSL rating of 1 (Unlimited), indicating no moisture sensitivity restrictions for storage and handling.

Q: What packaging formats are available for the RS1AB-13-F?

A: The RS1AB-13-F is supplied in Tape & Reel (TR) packaging format. The FR1A-13-F packaging format is not specified in the provided data.

Q: Why is the FR1A-13-F listed as obsolete?

A: The FR1A-13-F has been discontinued from active production by Diodes Incorporated. The RS1AB-13-F represents the active equivalent part for ongoing procurement and new design implementations.
