5STP 200 Glass Cartridge Fuse Equivalent & Substitute Parts

Part Overview

The 5STP 200 is a 200 mA, 250 V AC/DC slow-blow glass cartridge fuse with a 5mm x 20mm axial form factor, manufactured by Bel Fuse Inc. This component is classified as obsolete, though 951 pieces remain in stock. Due to its obsolete status, identifying equivalent and substitute parts is essential for ongoing design support, maintenance, and production continuity. Equivalent alternatives are available from multiple manufacturers with active product status and improved compliance certifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 5STP 200 is determined by strict equivalence across the following critical parameters:

• Current Rating: 200 mA (exact match required)
• Voltage Rating (AC): 250 V (exact match required)
• Fuse Type: Cartridge, Glass (exact match required)
• Response Time: Slow Blow (exact match required)
• Package / Case: 5mm x 20mm (Axial) (exact match required)
• Mounting Type: Through Hole (exact match required)
• Operating Temperature Range: -55°C ~ 125°C (minimum requirement)

All identified substitute parts meet these core electrical and mechanical criteria. Variations in secondary parameters such as Breaking Capacity, Melting I²t, DC Cold Resistance, and dimensional tolerances are noted but do not preclude substitution when primary parameters align.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: 5STP 200-R

The 5STP 200-R is the direct manufacturer equivalent from Bel Fuse Inc., maintaining identical electrical and mechanical specifications to the obsolete 5STP 200. This part is active in production, ROHS3 compliant, and carries expanded approval certifications including CCC and cULus. Inventory availability is substantial at 1,786 pieces. This is the preferred substitution path for direct replacement.

Secondary Recommendation: 0034.3110.PT

The SCHURTER Inc. 0034.3110.PT (FST 5x20 series) meets all core electrical parameters and maintains the same 35 A breaking capacity as the original 5STP 200. This part is active, ROHS3 compliant, and carries cURus certification. Dimensional tolerance variation (5.40mm x 22.50mm versus 5.50mm x 21.00mm) is within acceptable mechanical substitution range for through-hole mounting applications. Inventory is robust at 3,652 pieces.

Tertiary Recommendation: 0218.200MXEP

The Littelfuse Inc. 0218.200MXEP (218 series) provides full electrical equivalence with the broadest approval agency coverage, including CCC, CE, CSA, K-MARK, SEMKO, UL, and VDE. This part is active and ROHS3 compliant. Dimensional variation (5.80mm x 22.50mm) is within acceptable tolerance for through-hole applications. Inventory is available at 1,200 pieces.

Alternative Consideration: TSC-P-200MA and 5TTP 200-R

The OptiFuse TSC-P-200MA and Bel Fuse Inc. 5TTP 200-R both feature elevated breaking capacity (100 A) and higher melting I²t values. These parts are suitable for applications requiring enhanced fault tolerance. Both are active, ROHS3 compliant, and carry appropriate certifications. Selection of these alternatives should be based on specific circuit protection requirements rather than direct replacement necessity.

Frequently Asked Questions (FAQ)

Q: Can the 5STP 200-R directly replace the obsolete 5STP 200?

A: Yes. The 5STP 200-R is the direct manufacturer equivalent with identical electrical ratings (200 mA, 250 V AC/DC), fuse type (cartridge, glass), response time (slow blow), and package dimensions (5mm x 20mm axial). It is the recommended substitution.

Q: What is the difference between the 5STP 200-R and 5TTP 200-R?

A: Both are Bel Fuse Inc. products with identical current and voltage ratings. The primary differences are: 5TTP 200-R has a breaking capacity of 100 A (versus 35 A for 5STP 200-R) and a higher melting I²t of 0.476 (versus 0.15). The 5TTP 200-R is suitable for applications requiring enhanced fault tolerance.

Q: Are there dimensional differences between substitute parts?

A: Yes. The 0034.3110.PT measures 5.40mm x 22.50mm, and the 0218.200MXEP measures 5.80mm x 22.50mm, compared to the original 5.50mm x 21.00mm. These variations are within acceptable tolerance for through-hole mounting applications and do not affect electrical performance.

Q: Which substitute part has the best compliance certifications?

A: The 0218.200MXEP (Littelfuse Inc.) carries the broadest approval agency coverage: CCC, CE, CSA, K-MARK, SEMKO, UL, and VDE. All substitute parts are ROHS3 compliant.

Q: Can I use TSC-P-200MA as a direct replacement?

A: Yes, electrically and mechanically. The TSC-P-200MA meets all core parameters. However, it features a higher breaking capacity (100 A) and different melting I²t (0.2224), making it suitable for applications requiring enhanced protection characteristics.

Q: What is the inventory status of substitute parts?

A: All substitute parts are in active production with substantial inventory: 5STP 200-R (1,786 pcs), 5TTP 200-R (1,854 pcs), 0034.3110.PT (3,652 pcs), 0218.200MXEP (1,200 pcs), and TSC-P-200MA (5,772 pcs).
