Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ST-0600-BLT-STD is determined by the following critical parameters:

• Voltage - DC Spark Over (Nominal): Must be 600 V to maintain circuit protection specifications
• Number of Poles: Must be 2-pole configuration for electrical topology compatibility
• Mounting Type: Must be Through Hole to ensure mechanical and electrical fit within existing PCB designs
• Package / Case: Must be Axial Cylinder to maintain form factor compatibility
• Fail Short Characteristic: Must be No to preserve fail-safe behavior
• Regulatory Compliance: Must maintain ROHS3 and REACH compliance status

The identified substitute part 2027-60-BT1LF meets all critical substitution criteria while offering enhanced impulse discharge current rating and active product status.

Parameter Comparison

Engineering Selection Recommendations

The 2027-60-BT1LF is a direct functional substitute for the obsolete ST-0600-BLT-STD. Both components are manufactured by Bourns Inc. and share identical critical electrical parameters: 600V DC spark-over voltage, 2-pole configuration, and through-hole axial cylinder packaging. Both maintain ROHS3 compliance and REACH unaffected status.

The primary distinction is product lifecycle status: the ST-0600-BLT-STD is obsolete, while the 2027-60-BT1LF is active. The 2027-60-BT1LF provides specified impulse discharge current rating of 10kA (8/20µs), whereas the original part does not specify this parameter. The tolerance specification differs slightly (±15% versus ±12%), which remains within acceptable engineering margins for gas discharge tube applications.

Frequently Asked Questions (FAQ)

Q: Can the 2027-60-BT1LF be used as a direct replacement for the ST-0600-BLT-STD?

A: Yes. Both components share identical voltage rating (600V), pole configuration (2-pole), mounting type (through hole), and package form factor (axial cylinder). Electrical and mechanical compatibility is established.

Q: What is the significance of the impulse discharge current specification?

A: The 2027-60-BT1LF specifies 10kA impulse discharge current (8/20µs), indicating its surge handling capability. The original ST-0600-BLT-STD does not provide this specification. This parameter does not affect substitution eligibility but indicates the substitute's performance envelope.

Q: Does the tolerance difference (±12% vs ±15%) affect substitution?

A: No. Both tolerance ranges are acceptable for gas discharge tube applications and do not prevent substitution. The ±15% tolerance of the 2027-60-BT1LF remains within acceptable engineering margins for circuit protection.

Q: Are there any packaging or form factor differences?

A: No. Both components use axial cylinder packaging and through-hole mounting, ensuring identical PCB footprint and mechanical fit.

Q: What is the compliance status of the substitute part?

A: The 2027-60-BT1LF maintains ROHS3 compliance and REACH unaffected status, matching the original part's regulatory requirements.
