Substitute Part Grouping Explanation

Substitute parts for the SA16CA-TP are qualified based on the following critical parameters that determine functional equivalence:

• Voltage - Reverse Standoff (Typ): 16V
• Voltage - Breakdown (Min): 17.8V
• Voltage - Clamping (Max) @ Ipp: 26V
• Current - Peak Pulse (10/1000µs): ≥19.6A
• Power - Peak Pulse: 500W
• Operating Temperature Range: -55°C to 175°C
• Mounting Type: Through Hole
• Package / Case: DO-204AC or DO-15 Axial
• Type: Zener
• Bidirectional Channels: 1

The SA16CA manufactured by Taiwan Semiconductor Corporation qualifies as a direct substitute. This part maintains identical voltage specifications, equivalent peak pulse current (20A vs. 19.6A), matching power dissipation, and compatible through-hole axial packaging. Both parts share the same base product number (SA16) and are ROHS3 compliant with unlimited moisture sensitivity rating.

Parameter Comparison

Engineering Selection Recommendations

The SA16CA manufactured by Taiwan Semiconductor Corporation is electrically and mechanically equivalent to the SA16CA-TP. Both parts are active production components with ROHS3 compliance and identical regulatory status (REACH Unaffected, ECCN EAR99, HTSUS 8541.10.0080).

Selection between these parts should be based on:

• Packaging format requirements: SA16CA-TP is supplied in Cut Tape (CT) format, while SA16CA is supplied in Tape & Reel (TR) format. Choose based on assembly process and volume requirements.
• Current capacity margin: SA16CA provides 20A peak pulse current versus 19.6A for SA16CA-TP, offering a 2% higher current capacity within the same 500W power dissipation envelope.
• Inventory availability: SA16CA-TP has 2793 pieces in stock; SA16CA has 1621 pieces in stock.

Both parts maintain identical voltage protection characteristics and operating temperature specifications, ensuring functional interchangeability in general-purpose transient voltage suppression applications.

Frequently Asked Questions (FAQ)

Q: Can SA16CA be used as a direct replacement for SA16CA-TP?

A: Yes. Both parts have identical voltage specifications (16V standoff, 26V clamping), equivalent peak pulse current ratings, matching power dissipation, and compatible through-hole DO-15 axial packaging. The primary difference is packaging format (Cut Tape vs. Tape & Reel).

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

A: Cut Tape (CT) packaging provides individual component strips suitable for manual assembly or small-volume pick-and-place operations. Tape & Reel (TR) packaging supplies components on continuous reels optimized for high-volume automated assembly. Both formats contain the same component in identical DO-15 packages.

Q: Are there any compliance differences between SA16CA-TP and SA16CA?

A: No. Both parts are ROHS3 compliant, REACH unaffected, and share identical regulatory classifications (ECCN EAR99, HTSUS 8541.10.0080). Moisture sensitivity level is 1 (Unlimited) for both parts.

Q: Does the 20A vs. 19.6A current difference affect circuit design?

A: No. The SA16CA's 20A peak pulse current exceeds the SA16CA-TP's 19.6A specification while maintaining the same 500W power dissipation limit. This represents a 2% increase in current capacity and does not require circuit redesign.

Q: What is the operating temperature range for both parts?

A: Both parts operate across -55°C to 175°C. SA16CA-TP specifies this as ambient temperature (TA), while SA16CA specifies junction temperature (TJ). Both ranges are functionally equivalent for general-purpose applications.

Q: Can these parts be used interchangeably in existing designs?

A: Yes, provided the circuit board layout accommodates the through-hole DO-15 axial package format. No electrical redesign is required due to identical voltage and power specifications.
