Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the Littelfuse 036201.5H are qualified based on the following critical parameters:

• Current Rating: 1.5 A (exact match required)
• Voltage Rating: 250 V AC (exact match required)
• Fuse Type: Cartridge, Glass (exact match required)
• Package / Case: 8AG format with compatible physical dimensions
• Response Time: Fast Blow (exact match required)
• Mounting Type: Requires Holder (exact match required)

The Eaton BK/AGX-1-1/2 meets all substitution criteria. Physical dimension variance (1.042" L vs. 1.000" L) remains within 8AG package tolerance specifications and does not affect holder compatibility or electrical performance.

Parameter Comparison

Engineering Selection Recommendations

Both the Littelfuse 036201.5H and Eaton BK/AGX-1-1/2 are active products with current manufacturing support. Selection between these parts should be based on:

• Availability: Littelfuse 036201.5H has 971 units in stock; Eaton BK/AGX-1-1/2 has 831 units in stock
• Regulatory Compliance: Littelfuse carries CSA and UL approvals; Eaton carries cULus approval (combined Canadian/US certification)
• Supply Chain: Either part is suitable for new designs or replacement applications requiring 1.5 A 250 V fast-blow cartridge fuse protection

Both parts are RoHS non-compliant and carry identical moisture sensitivity ratings (MSL 1 - Unlimited).

Frequently Asked Questions (FAQ)

Q: Can the Eaton BK/AGX-1-1/2 be used as a direct replacement for the Littelfuse 036201.5H?

A: Yes. Both parts share identical electrical ratings (1.5 A, 250 V AC), fuse type (cartridge glass), response time (fast blow), and 8AG package format. The 0.042" length difference (1.042" vs. 1.000") is within 8AG specification tolerance and does not affect holder compatibility.

Q: Are there any compliance differences between these parts?

A: The Littelfuse part carries CSA and UL approvals. The Eaton part carries cULus approval, which represents combined Canadian and US certification. Both meet North American regulatory requirements for this fuse category.

Q: What is the significance of the 8AG package designation?

A: 8AG specifies a standardized cartridge fuse format: 1/4" diameter, approximately 1" length. This designation ensures mechanical compatibility with standard 8AG fuse holders regardless of manufacturer.

Q: Do these parts have different breaking capacities?

A: The Littelfuse 036201.5H does not specify breaking capacity. The Eaton BK/AGX-1-1/2 specifies 100 A breaking capacity at rated voltage. This parameter does not affect substitution eligibility for applications within the 1.5 A current rating.

Q: Are both parts suitable for AC and DC applications?

A: Both parts are rated for 250 V AC/DC operation. The fast-blow response time applies to both AC and DC circuit protection scenarios.
