SA10C-B Equivalent & Substitute Parts

Part Overview

The SA10C-B is a transient voltage suppressor (TVS) diode manufactured by Littelfuse Inc., designed for telecom applications. This component is a unidirectional Zener-type TVS diode in a DO-204AC (DO-15) axial through-hole package with a 10V reverse standoff voltage and 17V maximum clamping voltage at peak pulse current.

The SA10C-B carries an obsolete product status. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production or repair requirements for systems utilizing this component.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SA10C-B is determined by strict equivalence across the following electrical and mechanical parameters:

Critical Substitution Parameters:

• Voltage - Reverse Standoff (Typ): 10V
• Voltage - Clamping (Max) @ Ipp: 17V
• Current - Peak Pulse (10/1000µs): 30A
• Power - Peak Pulse: 500W
• Type: Zener
• Bidirectional Channels: 1
• Package / Case: DO-204AC, DO-15, Axial
• Mounting Type: Through Hole

Substitute parts must maintain identical electrical performance across all voltage and current ratings, identical package geometry, and compatible through-hole mounting characteristics. Packaging format (bulk, tape & reel) and product status do not affect electrical substitutability but influence procurement and inventory considerations.

Parameter Comparison

Engineering Selection Recommendations

SA10CA-B (Littelfuse Inc., Bulk Packaging)

The SA10CA-B is the primary substitute for the obsolete SA10C-B. Both components are manufactured by Littelfuse Inc. and maintain identical electrical specifications across all critical parameters. The SA10CA-B carries an active product status and ROHS3 compliance certification, ensuring long-term availability and regulatory alignment. The operating temperature range is -55°C to 175°C, which is narrower than the original part's -65°C to 175°C range; this difference is significant only for applications requiring operation below -55°C. The SA10CA-B is supplied in bulk packaging format.

SA10CA (Taiwan Semiconductor Corporation, Tape & Reel Packaging)

The SA10CA is an equivalent substitute manufactured by Taiwan Semiconductor Corporation with identical electrical performance to the SA10C-B. This part maintains all critical voltage, current, and power specifications. The SA10CA carries an active product status and ROHS3 compliance certification. The operating temperature range is -55°C to 175°C. This part is supplied in tape & reel format, suitable for automated assembly processes. REACH unaffected status is documented.

Operating Temperature Consideration

Both substitute parts operate to a minimum of -55°C, compared to the original SA10C-B minimum of -65°C. Applications requiring operation below -55°C require design review and alternative component selection.

Frequently Asked Questions (FAQ)

Q: Can SA10CA-B and SA10CA be used interchangeably with SA10C-B in the same circuit?

A: Yes. Both substitute parts maintain identical electrical specifications: 10V reverse standoff voltage, 17V clamping voltage, 30A peak pulse current, and 500W peak pulse power. The DO-204AC axial through-hole package is mechanically identical. Substitution is valid from an electrical and mechanical standpoint.

Q: What is the difference between SA10CA-B and SA10CA?

A: The primary differences are manufacturer and packaging format. SA10CA-B is manufactured by Littelfuse Inc. and supplied in bulk packaging. SA10CA is manufactured by Taiwan Semiconductor Corporation and supplied in tape & reel format. Electrical specifications are identical. Tape & reel packaging is preferred for high-volume automated assembly; bulk packaging is suitable for manual assembly or lower-volume applications.

Q: Does the operating temperature range difference affect substitutability?

A: The substitute parts operate from -55°C to 175°C, while the original SA10C-B operates from -65°C to 175°C. For applications requiring operation below -55°C, the substitute parts are not suitable. For applications within the -55°C to 175°C range, the operating temperature difference does not affect substitutability.

Q: Are the substitute parts RoHS compliant?

A: Yes. Both SA10CA-B and SA10CA carry ROHS3 compliance certification, meeting current regulatory requirements. The original SA10C-B is RoHS compliant but does not carry the ROHS3 designation.

Q: What packaging formats are available?

A: SA10CA-B is supplied in bulk packaging. SA10CA is supplied in tape & reel format. Bulk packaging is used for manual assembly or component stocking. Tape & reel packaging is used for automated pick-and-place assembly processes.

Q: Can I use these parts in new designs?

A: Yes. Both SA10CA-B and SA10CA carry active product status, ensuring ongoing availability and manufacturing support. These parts are suitable for new design implementations.

Q: Are there any compliance or certification differences?

A: SA10CA carries documented REACH unaffected status. Both substitute parts carry ROHS3 compliance. The original SA10C-B carries RoHS compliance without ROHS3 designation. For applications subject to REACH or ROHS3 regulatory requirements, the substitute parts provide current compliance documentation.
