P4SMA200C Equivalent & Substitute Parts

Part Overview

The P4SMA200C is a transient voltage suppressor (TVS) diode manufactured by Littelfuse Inc., designed for general-purpose voltage clamping applications. This bidirectional Zener diode operates with a reverse standoff voltage of 171V and provides clamping at 287.7V maximum. The part is classified as obsolete, making identification of suitable substitute components essential for ongoing design support and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the P4SMA200C are qualified based on the following critical parameters that must remain consistent:

• Reverse Standoff Voltage: 171V (Typ)
• Current - Peak Pulse (10/1000µs): 1.5A
• Power - Peak Pulse: 400W
• Mounting Type: Surface Mount
• Package / Case: DO-214AC or SMA variant
• Bidirectional Channels: 1
• Type: Zener

Acceptable variation exists in clamping voltage (274V to 287.7V maximum) and operating temperature range, provided the substitute maintains the core electrical performance envelope. All identified substitutes maintain these critical parameters within the allowed tolerance band for this product category.

Parameter Comparison

Engineering Selection Recommendations

Both P4SMA200CA (Eaton) and SMAJP4KE200CA-TP (Micro Commercial Co) are active production alternatives to the obsolete P4SMA200C. Selection between these substitutes is based on the following criteria:

P4SMA200CA (Eaton - Electronics Division): This part maintains identical reverse standoff voltage and peak pulse specifications. It is actively produced and RoHS compliant. The clamping voltage is reduced to 274V (from 287.7V), which is within acceptable tolerance for this product category. Operating temperature minimum is -55°C compared to -65°C on the original part. Packaging is specified as Tape & Reel (TR), suitable for automated assembly environments.

SMAJP4KE200CA-TP (Micro Commercial Co): This part also maintains the critical electrical parameters with identical reverse standoff voltage and peak pulse current. It offers an extended upper operating temperature of 175°C (versus 150°C on the original), providing additional thermal margin. The clamping voltage matches the Eaton substitute at 274V. Packaging is specified as Bulk. The SMAJ package variant is mechanically compatible with DO-214AC footprints.

Both substitutes are compliant with applicable environmental and regulatory standards. Selection should be based on procurement availability, packaging requirements (Tape & Reel versus Bulk), and thermal operating range requirements for the specific application.

Frequently Asked Questions (FAQ)

Q: Can P4SMA200CA or SMAJP4KE200CA-TP be used as direct replacements for P4SMA200C?

A: Yes, both parts qualify as substitutes based on matching reverse standoff voltage (171V), peak pulse current (1.5A), and power dissipation (400W). The clamping voltage reduction from 287.7V to 274V is within acceptable tolerance for this TVS diode category. Both maintain surface mount DO-214AC package compatibility.

Q: What is the significance of the clamping voltage difference between P4SMA200C (287.7V) and the substitutes (274V)?

A: The clamping voltage represents the maximum voltage across the diode during transient suppression. The 13.7V reduction in maximum clamping voltage on the substitute parts provides slightly improved transient suppression performance while remaining within the electrical specification envelope for this product category.

Q: Are there temperature range considerations when selecting between P4SMA200CA and SMAJP4KE200CA-TP?

A: P4SMA200CA operates from -55°C to 150°C, while SMAJP4KE200CA-TP extends to 175°C maximum. The original P4SMA200C operates from -65°C to 150°C. If the application requires operation below -55°C, neither substitute is suitable. If operation above 150°C is required, SMAJP4KE200CA-TP provides additional thermal margin.

Q: What is the difference between Tape & Reel and Bulk packaging?

A: Tape & Reel (TR) packaging is formatted for automated pick-and-place assembly equipment, typical in high-volume manufacturing. Bulk packaging is suitable for manual assembly or lower-volume applications. Selection depends on production methodology and assembly equipment capabilities.

Q: Are both substitutes RoHS compliant?

A: P4SMA200CA is RoHS compliant. SMAJP4KE200CA-TP is listed as REACH Unaffected. Both meet current environmental compliance requirements for electronic component procurement.

Q: Is the SMAJ package variant mechanically compatible with SMA footprints?

A: SMAJP4KE200CA-TP uses the DO-214AC (SMAJ) package, which is mechanically compatible with standard SMA footprints used by P4SMA200C. Both packages are surface mount variants of the DO-214AC form factor.
