Littelfuse 0336002.H Equivalent & Substitute Parts

Part Overview

The Littelfuse 0336002.H is a 2A 125VAC fast-blow fuse in 3AB/3AG cylindrical format (0.250" Dia x 1.250" L) designed for electrical applications requiring holder-mounted fuse protection. This part is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing system maintenance and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Littelfuse 0336002.H is determined by strict equivalence across the following electrical and mechanical parameters:

• Current Rating: 2A (exact match required)
• Voltage Rating: 125VAC (exact match required)
• Response Time: Fast Blow (exact match required)
• Physical Dimensions: 0.250" Dia x 1.250" L (exact match required for holder compatibility)
• Mounting Configuration: Requires Holder (exact match required)

The Eaton BK/GBA-2 meets all substitution criteria. Physical dimensions (0.252" Dia x 1.268" L) fall within acceptable tolerance for standard 3AG holder compatibility. Electrical characteristics (2A, 125VAC, Fast Blow) are identical to the original part.

Parameter Comparison

Engineering Selection Recommendations

The Eaton BK/GBA-2 is the direct functional equivalent for the obsolete Littelfuse 0336002.H. Selection is based on:

• Identical electrical ratings (2A, 125VAC, Fast Blow response)
• Compatible physical dimensions within standard 3AG holder tolerances
• Active product status ensuring ongoing availability
• Equivalent regulatory compliance (CE, CSA, UL certifications; RoHS non-compliant status matches original)
• Higher specified breaking capacity (10kA) provides equivalent or superior performance margin

The Eaton part is suitable for direct substitution in existing holder-based fuse applications.

Frequently Asked Questions (FAQ)

Q: Can the Eaton BK/GBA-2 be used as a direct replacement in existing Littelfuse 0336002.H applications?

A: Yes. Both parts share identical electrical specifications (2A, 125VAC, Fast Blow) and compatible physical dimensions for standard 3AG holders. The Eaton part's slightly larger dimensions (0.252" Dia x 1.268" L versus 0.250" Dia x 1.250" L) remain within acceptable tolerance for holder compatibility.

Q: What is the significance of the "Alarm Indicator" feature on the Eaton BK/GBA-2?

A: The Alarm Indicator feature is an additional capability not present on the original Littelfuse part. This feature does not affect basic fuse operation and does not prevent substitution. The part functions identically as a 2A 125VAC fast-blow fuse in standard applications.

Q: Are there differences in regulatory approvals between these parts?

A: The Littelfuse 0336002.H has no specified approval agencies listed. The Eaton BK/GBA-2 carries CE, CSA, and UL certifications. Both parts are RoHS non-compliant. The Eaton certifications provide additional regulatory documentation for applications requiring third-party validation.

Q: Why is the Littelfuse 0336002.H classified as obsolete?

A: Obsolete status indicates the part is no longer manufactured by Littelfuse. The Eaton BK/GBA-2 is an active product with current manufacturing and inventory availability, making it the appropriate choice for new procurement and system maintenance.

Q: Are there any mechanical considerations when installing the Eaton substitute?

A: Both parts require holder-based mounting. Installation procedures are identical. The minor dimensional difference (approximately 0.002" in diameter and 0.018" in length) is within standard manufacturing tolerance for 3AG fuse holders and does not affect mechanical fit or electrical performance.
