Equivalent & Substitute Parts for 5HTP 8-R Ceramic Fuse

Part Overview

The 5HTP 8-R is an 8 A, 250 V AC ceramic cartridge fuse manufactured by Bel Fuse Inc. in a 5mm x 20mm axial through-hole package. This slow-blow fuse is designed for circuit protection in AC applications with a breaking capacity of 1.5 kA at rated voltage. The part is active in production with full RoHS3 compliance and international approvals (CE, CSA, cULus, PSE). Equivalent substitute parts may be required due to supply chain constraints, regional availability, or specific application requirements while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 5HTP 8-R is determined by strict alignment of the following electrical and mechanical parameters:

• Current Rating: 8 A (exact match required)
• Voltage Rating (AC): 250 V (exact match required)
• Package / Case: 5mm x 20mm (Axial) (exact match required)
• Fuse Type: Cartridge, Ceramic (exact match required)
• Mounting Type: Through Hole (exact match required)
• Response Time: Slow Blow (exact match required)
• Operating Temperature Range: -55°C ~ 125°C (minimum requirement)
• RoHS3 Compliance: Required

The following parts meet all substitution criteria:

1. 0001.2513.TR (SCHURTER Inc.) – Meets all core electrical and mechanical parameters with additional DC voltage rating (150 V DC) and equivalent breaking capacity specifications.
2. 0215008.MXEP (Littelfuse Inc.) – Meets all core electrical and mechanical parameters with equivalent breaking capacity and extended approval agency certifications.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts are active products with full RoHS3 compliance and meet the core electrical and mechanical requirements for direct substitution with the 5HTP 8-R.

0001.2513.TR (SCHURTER Inc.) provides additional DC voltage rating capability (150 V DC) and is certified by cURus. This part is suitable for applications requiring dual AC/DC voltage protection or where DC circuit protection is anticipated.

0215008.MXEP (Littelfuse Inc.) maintains AC-only specifications matching the original 5HTP 8-R and offers extended approval agency coverage (CE, CSA, KC, PSE, SEMKO, UL, VDE), providing broader regional compliance recognition. This part is suitable for applications requiring maximum international certification scope.

Both parts are physically compatible with standard 5mm x 20mm fuse holders and maintain the slow-blow response characteristic required for inrush current tolerance in AC circuits.

Frequently Asked Questions (FAQ)

Q: Can 0001.2513.TR be used as a direct replacement for 5HTP 8-R in AC-only circuits?

A: Yes. The 0001.2513.TR meets all AC electrical specifications (8 A, 250 V AC) and mechanical requirements (5mm x 20mm axial, through-hole, slow-blow ceramic cartridge). The additional DC voltage rating does not affect AC circuit operation.

Q: What is the difference in melting I²t values between the three parts?

A: The melting I²t values differ: 5HTP 8-R (330), 0001.2513.TR (268), and 0215008.MXEP (209.88). These variations reflect different thermal characteristics within the same 8 A current rating. Selection should be based on specific circuit thermal requirements and time-current curve compatibility.

Q: Are there physical size differences that affect installation?

A: Minor dimensional variations exist. The 5HTP 8-R is 5.50mm diameter x 21.00mm length, while both substitutes are approximately 5.40-5.80mm diameter x 22.50mm length. These differences are within standard fuse holder tolerances for 5mm x 20mm cartridge fuses and do not affect mechanical compatibility.

Q: Which substitute part has the broadest international approvals?

A: The 0215008.MXEP (Littelfuse) carries approvals from CE, CSA, KC, PSE, SEMKO, UL, and VDE, providing the widest regional certification coverage compared to the 5HTP 8-R (CE, CSA, cULus, PSE) and 0001.2513.TR (cURus).

Q: Can these parts be used interchangeably in the same circuit board design?

A: Yes, all three parts are mechanically and electrically compatible for use in standard 5mm x 20mm through-hole fuse holders. No circuit board modifications are required for substitution.
