Key Parameters

Substitute Part Grouping Explanation

Substitution of the P4SMA7.5CA BK is determined by strict equivalence across the following critical parameters:

• Voltage - Reverse Standoff: 7.5V (nominal)
• Voltage - Clamping (Max) @ Ipp: 12.9V
• Current - Peak Pulse (10/1000µs): 31A
• Package / Case: DO-214AC, SMA
• Bidirectional Channels: 1
• Type: Zener

The SMAJ7.5CA-13-F manufactured by Diodes Incorporated meets all these electrical and mechanical specifications. Both parts share identical voltage ratings, peak pulse current capability, and package configuration, making them functionally interchangeable for the specified application category of general-purpose transient voltage suppression.

Parameter Comparison

Engineering Selection Recommendations

The SMAJ7.5CA-13-F is the primary substitute for the P4SMA7.5CA BK. This part is manufactured by Diodes Incorporated and maintains active product status, ensuring ongoing availability and supply chain support. The substitute part is RoHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component procurement.

Selection of the SMAJ7.5CA-13-F eliminates obsolescence risk while maintaining full electrical and mechanical compatibility with the original design. The active product status provides long-term sourcing stability compared to the obsolete P4SMA7.5CA BK.

Frequently Asked Questions (FAQ)

Q: Can the SMAJ7.5CA-13-F be used as a direct replacement for the P4SMA7.5CA BK?

A: Yes. Both parts share identical electrical specifications (7.5V reverse standoff, 12.9V clamping voltage, 31A peak pulse current) and the same SMA package configuration. No circuit modifications are required.

Q: What is the difference between the P4SMA7.5CA BK and SMAJ7.5CA-13-F?

A: The primary difference is manufacturer and product status. The P4SMA7.5CA BK (Central Semiconductor) is obsolete, while the SMAJ7.5CA-13-F (Diodes Incorporated) is active. All electrical and mechanical parameters are equivalent.

Q: Does packaging format affect substitution?

A: The P4SMA7.5CA BK is supplied in standard packaging, while the SMAJ7.5CA-13-F is supplied in Tape & Reel (TR) format. Both use the same SMA package footprint and are compatible with standard surface-mount assembly processes.

Q: Are there compliance differences between these parts?

A: The SMAJ7.5CA-13-F carries RoHS3 compliance and REACH unaffected status. Both parts share the same ECCN (EAR99) and HTSUS classification (8541.10.0080).

Q: What inventory considerations apply to these parts?

A: The P4SMA7.5CA BK has 1076 pieces in stock but is obsolete. The SMAJ7.5CA-13-F has 5300 pieces in stock and active product status, providing superior long-term availability.
