5TTP 200-R Equivalent & Substitute Parts

Part Overview

The 5TTP 200-R is a 200 mA, 250 V AC/DC slow-blow glass cartridge fuse in a 5mm x 20mm through-hole package, manufactured by Bel Fuse Inc. This component is Active in product status and widely used in electronic circuit protection applications. Equivalent and substitute parts are identified when design requirements necessitate alternative sourcing, inventory optimization, or manufacturer selection based on identical or compatible electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 5TTP 200-R are qualified based on the following mandatory 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 Breaking Capacity, Melting I²t, DC Cold Resistance, and approval certifications are noted but do not disqualify substitution when the primary parameters align.

Parameter Comparison

Engineering Selection Recommendations

All four parts—5TTP 200-R, 5STP 200-R, 0239.200HXEP, and TSC-P-200MA—are Active products with ROHS3 compliance and meet the mandatory electrical and mechanical substitution criteria.

The 5TTP 200-R and TSC-P-200MA both provide 100A breaking capacity, while the 5STP 200-R and 0239.200HXEP provide 35A breaking capacity. Selection between these groups depends on circuit protection requirements at rated voltage.

Approval certifications vary across manufacturers: the 5TTP 200-R carries CE, CSA, and cULus approvals; the 5STP 200-R includes additional certifications (CCC, IMQ, SEMKO, VDE); the 0239.200HXEP includes CE, CSA, KC, and UL; and the TSC-P-200MA carries cULus and UL 248 approvals. Component selection should align with regional regulatory requirements and end-application standards.

Frequently Asked Questions (FAQ)

Q: Can the 5STP 200-R replace the 5TTP 200-R in all applications?

A: The 5STP 200-R meets all mandatory electrical and mechanical parameters (200 mA, 250 V AC, slow-blow, 5mm x 20mm, through-hole). However, the 5TTP 200-R provides 100A breaking capacity while the 5STP 200-R provides 35A. Substitution is valid only when the 35A breaking capacity is acceptable for the circuit design.

Q: What is the difference between the Littelfuse 0239.200HXEP and the Bel Fuse 5TTP 200-R?

A: Both parts are electrically and mechanically equivalent (200 mA, 250 V, slow-blow, 5mm x 20mm). The 0239.200HXEP has a slightly longer physical dimension (0.846" L vs. 0.827" L) and different DC cold resistance (3.8725 Ohms vs. 4.66 Ohms). Approval certifications also differ. Physical fit should be verified in space-constrained applications.

Q: Is the TSC-P-200MA from OptiFuse a direct substitute?

A: Yes. The TSC-P-200MA meets all mandatory parameters and provides 100A breaking capacity matching the 5TTP 200-R. Approval certifications (cULus, UL 248) differ from the original part, so compliance verification against end-application standards is required.

Q: Do all substitute parts have the same physical dimensions?

A: Nominal dimensions are 5mm x 20mm for all parts. The 0239.200HXEP has a specified length of 0.846" (21.50mm) compared to 0.827" (21.00mm) for other parts. Physical clearance verification is necessary in applications with tight mechanical tolerances.

Q: Are all substitute parts RoHS compliant?

A: Yes. All four parts—5TTP 200-R, 5STP 200-R, 0239.200HXEP, and TSC-P-200MA—are ROHS3 compliant.
