5TTP 200 Equivalent & Substitute Parts

Part Overview

The 5TTP 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, making identification of functionally equivalent alternatives essential for ongoing system maintenance and component procurement. Substitute parts must maintain identical electrical ratings, mechanical dimensions, and thermal characteristics to ensure direct compatibility in existing circuit designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 5TTP 200 is determined by strict equivalence across the following 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 (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 approval agencies do not preclude substitution when primary parameters align.

Engineering Selection Recommendations

5TTP 200-R (Bel Fuse Inc.) — Direct manufacturer successor with active product status. Maintains identical electrical and mechanical specifications to the 5TTP 200. Achieves ROHS3 compliance and cULus certification. Melting I²t (0.476) and DC cold resistance (4.66 Ohms) are within 1% of the original part. Recommended as the primary replacement option.

5STP 200-R (Bel Fuse Inc.) — Active alternative from the same manufacturer. Meets all core electrical and mechanical requirements. Offers expanded approval agency coverage (CCC, CE, CSA, cULus, IMQ, SEMKO, VDE). Breaking capacity is reduced to 35A and melting I²t is significantly lower (0.15), reflecting different thermal response characteristics. Suitable for applications where lower breaking capacity is acceptable.

TSC-P-200MA (OptiFuse) — Active cross-manufacturer equivalent. Maintains all primary electrical and mechanical parameters. Achieves ROHS3 compliance and cULus/UL 248 certification. Breaking capacity matches the original part at 100A. Melting I²t (0.2224) differs from the original specification. Represents a viable alternative from an independent manufacturer.

Frequently Asked Questions (FAQ)

Q: Can the 5TTP 200-R be used as a direct replacement for the 5TTP 200?

A: Yes. The 5TTP 200-R maintains identical current rating (200 mA), voltage rating (250 V AC), fuse type (cartridge, glass), response time (slow blow), package dimensions (5mm x 20mm axial), and mounting type (through hole). It is the active successor to the obsolete 5TTP 200.

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

A: Both parts share identical electrical ratings and mechanical form factors. The primary differences are breaking capacity (5TTP 200-R: 100A vs. 5STP 200-R: 35A) and melting I²t (5TTP 200-R: 0.476 vs. 5STP 200-R: 0.15). The 5STP 200-R has broader approval agency coverage. Selection depends on circuit breaking capacity requirements.

Q: Is the TSC-P-200MA from OptiFuse compatible with the 5TTP 200?

A: Yes. The TSC-P-200MA meets all core substitution criteria: 200 mA current rating, 250 V AC voltage rating, cartridge glass fuse type, slow-blow response, 5mm x 20mm package, and through-hole mounting. It is manufactured by a different supplier but maintains electrical and mechanical equivalence.

Q: Are there RoHS compliance differences between these parts?

A: The original 5TTP 200 is RoHS non-compliant. All three substitute parts (5TTP 200-R, 5STP 200-R, TSC-P-200MA) are ROHS3 compliant, meeting current environmental regulations.

Q: Do these parts have the same approval certifications?

A: No. The 5TTP 200 carries CE, CSA, and UL certifications. The 5TTP 200-R adds cULus. The 5STP 200-R includes additional certifications (CCC, IMQ, SEMKO, VDE). The TSC-P-200MA carries cULus and UL 248. All certifications are sufficient for general industrial applications; specific application requirements may dictate certification preferences.

Q: Can I use the 5STP 200-R in a circuit designed for the 5TTP 200?

A: Yes, provided the circuit does not require the higher breaking capacity of the original part. The 5STP 200-R has a breaking capacity of 35A compared to the 5TTP 200's 100A. If the circuit is designed for 100A breaking capacity, the 5STP 200-R may not provide adequate protection in fault conditions.
