Key Parameters

Substitute Part Grouping Explanation

Equivalent substitution for the Bourns 2027-09-BT1 is determined by strict alignment of the following critical parameters:

• Voltage - DC Spark Over (Nominal): 90 V
• Impulse Discharge Current (8/20µs): 10000A (10kA)
• Number of Poles: 2
• Mounting Type: Through Hole
• Package / Case: Axial Cylinder
• Fail Short Characteristic: No

The Littelfuse SL1411A090A meets all mandatory electrical and mechanical parameters required for direct substitution. Both components share identical spark-over voltage, discharge current rating, pole configuration, and mounting characteristics. Packaging format differs between Tape & Reel (main part) and Cut Tape (substitute), which affects supply chain logistics but does not impact electrical performance or circuit compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the Bourns 2027-09-BT1 and Littelfuse SL1411A090A are Active products suitable for 90V, 10kA GDT applications. Selection between these components should consider the following factors:

Compliance Requirements: The Littelfuse SL1411A090A offers ROHS3 compliance and REACH Unaffected status, making it preferable for applications subject to environmental regulations. The Bourns 2027-09-BT1 is RoHS non-compliant and REACH Affected, which may restrict use in regulated markets or end applications.

Supply Chain Considerations: The Littelfuse part provides higher current inventory (1600 units) compared to the Bourns part (834 units). Packaging format differs: Bourns supplies in Tape & Reel format while Littelfuse supplies in Cut Tape format. Packaging selection depends on assembly process requirements and volume handling procedures.

Electrical Equivalence: Both components deliver identical electrical performance with 90V spark-over voltage and 10kA impulse discharge current in 2-pole through-hole axial cylinder packages. Circuit-level substitution is direct without design modification.

Frequently Asked Questions (FAQ)

Q: Can the Littelfuse SL1411A090A directly replace the Bourns 2027-09-BT1 in existing designs?

A: Yes. Both components share identical electrical ratings (90V spark-over, 10kA discharge current), pole configuration (2-pole), mounting type (through-hole), and package form (axial cylinder). No circuit redesign is required for substitution.

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

A: Tape & Reel packaging supplies components on continuous carrier tape wound on reels, suitable for high-volume automated assembly. Cut Tape supplies the same carrier tape in smaller pre-cut lengths, typically for lower-volume or manual assembly processes. Electrical performance is identical; packaging choice depends on assembly equipment and order volume.

Q: Does the RoHS compliance difference affect circuit performance?

A: No. RoHS compliance relates to material composition and environmental regulations, not electrical function. The Littelfuse part's ROHS3 compliance makes it suitable for regulated applications and markets with environmental restrictions. The Bourns part's non-compliance may limit use in certain jurisdictions or end-market applications.

Q: Are there tolerance differences between these parts?

A: The Bourns 2027-09-BT1 specifies ±20% tolerance on spark-over voltage. The Littelfuse SL1411A090A does not provide tolerance specification in available data. Both parts meet the 90V nominal requirement for circuit protection purposes.

Q: Which part should be selected for new designs?

A: For new designs, the Littelfuse SL1411A090A is recommended due to ROHS3 compliance, REACH Unaffected status, higher inventory availability, and Active product status. This selection ensures regulatory compliance and supply chain continuity for long-term production.
