5STP 200-R Equivalent & Substitute Parts

Part Overview

The 5STP 200-R is a 200 mA, 250 V AC/DC slow-blow glass cartridge fuse in a 5mm x 20mm axial package manufactured by Bel Fuse Inc. This component is actively produced and widely used in electronic equipment requiring overcurrent protection. Equivalent and substitute parts are identified based on matching electrical ratings, mechanical dimensions, and functional characteristics to ensure direct replacement capability in circuit designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following critical parameters:

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

All identified substitute parts meet these core electrical and mechanical parameters. Variations in secondary characteristics such as breaking capacity, melting I²t, DC cold resistance, and dimensional tolerances are noted but do not preclude substitution when primary parameters align.

Engineering Selection Recommendations

All five parts listed are active products with ROHS3 compliance. Selection among these substitutes should be based on:

Approval Agency Requirements: The 5STP 200-R carries approvals from CCC, CE, CSA, cULus, IMQ, SEMKO, and VDE. The 0218.200MXEP (Littelfuse) provides the broadest certification coverage including CCC, CE, CSA, K-MARK, SEMKO, UL, and VDE. The 5TTP 200-R and TSC-P-200MA carry cULus and UL 248 certifications respectively. The 0034.3110.PT (SCHURTER) carries cURus approval. Selection should align with the specific regulatory requirements of the target application.

Breaking Capacity Considerations: The 5TTP 200-R and TSC-P-200MA offer 100A breaking capacity compared to 35A for the 5STP 200-R, 0034.3110.PT, and 0218.200MXEP. Higher breaking capacity provides enhanced protection in high-fault-current environments.

Dimensional Tolerances: The 0034.3110.PT exhibits slightly different physical dimensions (5.40mm x 22.50mm) and the 0218.200MXEP (5.80mm x 22.50mm) compared to the nominal 5.50mm x 21.00mm specification. These minor variations may affect fit in space-constrained applications.

Frequently Asked Questions (FAQ)

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

A: Yes. Both parts share identical electrical ratings (200 mA, 250 V AC), fuse type (cartridge glass), response time (slow blow), package dimensions (5mm x 20mm), and operating temperature range (-55°C ~ 125°C). The 5TTP 200-R offers higher breaking capacity (100A vs. 35A) and different melting I²t characteristics, but these do not prevent direct substitution when primary electrical parameters match.

Q: Are there dimensional differences between substitute parts?

A: Minor dimensional variations exist. The 0034.3110.PT measures 5.40mm x 22.50mm and the 0218.200MXEP measures 5.80mm x 22.50mm, compared to the nominal 5.50mm x 21.00mm. These tolerances may affect mechanical fit in applications with tight spatial constraints. Verify mounting hole spacing and clearances before substitution.

Q: Which substitute part has the best regulatory coverage?

A: The 0218.200MXEP (Littelfuse) carries the most comprehensive approvals: CCC, CE, CSA, K-MARK, SEMKO, UL, and VDE. Selection should match the specific regulatory requirements of your target market and application.

Q: What is the significance of melting I²t values?

A: Melting I²t indicates the thermal energy required to melt the fuse element. Values range from 0.15 (5STP 200-R) to 0.476 (5TTP 200-R). Lower values indicate faster response to overcurrent conditions. All listed parts are slow-blow fuses and remain functionally equivalent for standard overcurrent protection applications.

Q: Can I use these parts interchangeably in production?

A: Yes, provided that approval agency certifications align with your application requirements and dimensional tolerances are verified for your specific PCB layout and mechanical assembly. All listed parts meet the core electrical and mechanical substitution criteria.
