SA82CB0 Equivalent & Substitute Parts

Part Overview

The SA82CB0 is a thermal cutoff (TCO) breaker manufactured by Bourns Inc., designed for AC/DC applications with a functioning temperature of 82°C (180°F) and a reset temperature of 40°C (104°F). This component is classified as obsolete, which necessitates identification of active equivalent parts for ongoing design and procurement requirements. The SA82CB0 operates at 12 A current rating with a 28 V DC voltage rating and is housed in a nonstandard package configuration suitable for surface-mount applications.

Substitute Part Grouping Explanation

The SA82SB0 qualifies as a direct substitute for the SA82CB0 based on the following alignment of critical electrical and mechanical parameters:

• Identical manufacturer (Bourns Inc.) and series designation (SA)
• Identical functioning temperature (82°C / 180°F) and reset temperature (40°C / 104°F)
• Identical voltage rating (28 V DC)
• Identical package classification (nonstandard)
• Identical approval certifications (cUL, TUV, UL)
• Identical RoHS and REACH compliance status

The primary distinction between these parts is the current rating: SA82CB0 is rated at 12 A, while SA82SB0 is rated at 25 A. This difference permits the SA82SB0 to function in applications requiring higher current capacity while maintaining all other thermal and electrical characteristics. The SA82SB0 is currently in active production status, whereas the SA82CB0 is obsolete.

Parameter Comparison

Engineering Selection Recommendations

The SA82SB0 is the appropriate substitute for the SA82CB0 in applications where the original part is no longer available. Both components maintain identical thermal trip points (82°C functioning, 40°C reset) and voltage specifications (28 V DC), ensuring functional compatibility in existing circuit designs. The SA82SB0 carries active product status with full availability, whereas the SA82CB0 is obsolete. Both parts maintain equivalent compliance certifications (cUL, TUV, UL) and RoHS3 compliance, satisfying regulatory requirements for new designs and production runs. The increased current rating of the SA82SB0 (25 A versus 12 A) provides additional design margin and does not introduce incompatibility when substituted into circuits originally specified for 12 A operation.

Frequently Asked Questions (FAQ)

Q: Can SA82SB0 be used as a direct replacement for SA82CB0?

A: Yes. Both parts share identical thermal characteristics (82°C functioning temperature, 40°C reset temperature), voltage rating (28 V DC), package type (nonstandard), and regulatory certifications (cUL, TUV, UL). The SA82SB0 is suitable for direct substitution.

Q: What is the primary difference between SA82CB0 and SA82SB0?

A: The current rating differs: SA82CB0 is rated at 12 A, while SA82SB0 is rated at 25 A. All other electrical and thermal parameters are identical.

Q: Why is the SA82CB0 marked as obsolete?

A: The SA82CB0 has been discontinued by the manufacturer. The SA82SB0 represents the active equivalent in the Bourns SA series thermal cutoff lineup.

Q: Are packaging specifications identical between these parts?

A: Yes. Both the SA82CB0 and SA82SB0 use nonstandard package configurations. The SA82SB0 is available in Tape & Reel (TR) packaging for production environments.

Q: Do both parts meet the same regulatory standards?

A: Yes. Both SA82CB0 and SA82SB0 carry identical approval certifications (cUL, TUV, UL) and maintain ROHS3 compliance and REACH unaffected status.
