Key Parameters

Substitute Part Grouping Explanation

Substitution of the P4SMA9.0CA BK is determined by strict equivalence across the following critical parameters:

• Voltage - Reverse Standoff: 9V (typ)
• Voltage - Clamping (Max) @ Ipp: 15.4V
• Current - Peak Pulse (10/1000µs): 26A
• Power - Peak Pulse: 400W
• Package / Case: DO-214AC, SMA
• Operating Temperature Range: -55°C ~ 150°C (TJ)
• Bidirectional Channels: 1
• Type: Zener

The substitute part SMAJ9.0CA-13-F manufactured by Diodes Incorporated meets all specified electrical and mechanical parameters. This part maintains identical voltage ratings, current handling capability, power dissipation, package configuration, and temperature operating range as the original component.

Frequently Asked Questions (FAQ)

Q: Can the SMAJ9.0CA-13-F be used as a direct replacement for the P4SMA9.0CA BK?

A: Yes. Both components share identical electrical specifications including reverse standoff voltage (9V), clamping voltage (15.4V), peak pulse current (26A), and power dissipation (400W). Both use the same DO-214AC SMA package and operate across the same temperature range (-55°C ~ 150°C).

Q: What is the primary difference between these two parts?

A: The P4SMA9.0CA BK is obsolete, while the SMAJ9.0CA-13-F is an active product. The substitute part is manufactured by Diodes Incorporated and is available in Tape & Reel packaging. Both parts meet identical functional and mechanical requirements.

Q: Are there any compliance or certification differences?

A: The SMAJ9.0CA-13-F carries RoHS3 compliance and REACH unaffected status. Both parts share equivalent moisture sensitivity levels (MSL 1, Unlimited).

Q: Does the packaging format affect compatibility?

A: Both parts use the DO-214AC SMA surface-mount package. The SMAJ9.0CA-13-F is supplied in Tape & Reel format, which is standard for automated assembly. This does not affect electrical or mechanical compatibility.

Q: What parameters must remain constant for substitution?

A: Substitution requires equivalence in reverse standoff voltage (9V), breakdown voltage (10V minimum), clamping voltage (15.4V maximum), peak pulse current (26A), power dissipation (400W), package type (DO-214AC SMA), and operating temperature range (-55°C ~ 150°C).
