Substitute Part Grouping Explanation

Substitution of the RABF156-13 is determined by strict equivalence across the following electrical and mechanical parameters:

• Voltage - Peak Reverse (Max): 600 V
• Current - Average Rectified (Io): 1.5 A
• Voltage - Forward (Vf) (Max) @ If: 1.3 V @ 1.5 A
• Current - Reverse Leakage @ Vr: 5 µA @ 600 V
• Operating Temperature Range: -55°C ~ 150°C (TJ)
• Diode Type: Single Phase
• Technology: Standard
• Mounting Type: Surface Mount
• Package / Case: 4-SMD, Gull Wing

The FTB6F-15F meets all specified electrical parameters and mechanical requirements, qualifying as a parametric equivalent. Both parts share identical voltage ratings, current specifications, forward voltage characteristics, and temperature operating range. Surface mount configuration and gull wing package geometry are compatible for direct board-level substitution.

Parameter Comparison

Engineering Selection Recommendations

The FTB6F-15F qualifies as a direct parametric equivalent to the RABF156-13 based on complete electrical and mechanical specification alignment. Both components are ROHS3 compliant and carry identical moisture sensitivity ratings, ensuring regulatory and environmental compatibility. The obsolete status of the RABF156-13 makes the FTB6F-15F a suitable alternative for new procurement and design continuity applications. Packaging format differences (Tape & Reel versus Cut Tape) do not affect electrical performance or board-level functionality.

Frequently Asked Questions (FAQ)

Q: Can the FTB6F-15F be used as a direct replacement for the RABF156-13?

A: Yes. The FTB6F-15F meets all electrical specifications, operating temperature range, and mechanical package requirements of the RABF156-13. Both components are 4-SMD gull wing surface mount devices with identical voltage and current ratings.

Q: Are there differences in packaging that affect substitution?

A: The RABF156-13 is supplied in Tape & Reel format while the FTB6F-15F is supplied in Cut Tape format. This difference affects procurement and handling but does not impact electrical performance or board-level compatibility.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the RABF156-13 and FTB6F-15F are ROHS3 compliant with MSL rating of 1 (Unlimited), ensuring equivalent environmental and regulatory compliance.

Q: What are the critical parameters for substitution?

A: Voltage rating (600 V), current rating (1.5 A), forward voltage (1.3 V @ 1.5 A), reverse leakage (5 µA @ 600 V), and operating temperature range (-55°C ~ 150°C) must remain constant for functional equivalence.

Q: Is the FTB6F-15F available in higher inventory quantities?

A: Yes. The FTB6F-15F has 14,362 pieces in stock compared to 846 pieces for the RABF156-13, providing improved procurement availability.
