Substitute Part Grouping Explanation

Substitution of the 5SF 200-R is determined by strict equivalence across the following critical parameters:

Current Rating: 200 mA (exact match required)
Voltage Rating: 250 V AC (exact match required)
Package Dimensions: 5mm x 20mm (exact match required)
Response Time: Fast Blow (exact match required)
Fuse Type: Cartridge, Glass (exact match required)
Breaking Capacity: 35A (exact match required)

All substitute parts listed below meet these criteria. Secondary parameters such as melting I²t, DC cold resistance, and specific approval agencies may vary within acceptable engineering tolerances for this component category, but do not affect functional substitutability when the primary parameters are matched.

Engineering Selection Recommendations

All listed substitute parts are active products with current manufacturing status, providing supply continuity for the obsolete 5SF 200-R. Selection among these equivalents should be based on:

Compliance Requirements: The 5SF 200-R carries approvals from CCC, CE, CSA, cURus, IMQ, SEMKO, and VDE. Substitute parts maintain overlapping certification coverage. The Littelfuse 217 series (0217.200MXBP, 0217.200MXP, 0217.200TXP, 0217.200VXP, 0217.200HXP) provides the broadest approval alignment including CCC, CE, CSA, K-MARK/KC, SEMKO, UL, and VDE. The SCHURTER 0034.1509 covers CCC, cURus, and VDE. Eaton products (BK/S500-200-R, GDB-200MA) provide BSI, CCC, CSA, cULus, IMQ, SEMKO, and VDE certifications.

Resistance Characteristics: DC cold resistance varies across substitutes (1.1 to 6.8 Ohms). Applications sensitive to circuit resistance should prioritize Littelfuse 217 series parts (1.7 Ohms) or SCHURTER 0034.1509, which maintain resistance profiles closest to the original 5SF 200-R (1.1 Ohms). Eaton products exhibit higher resistance (6.8 Ohms) and should be selected only when circuit design accommodates this parameter.

Melting I²t Variation: Littelfuse 235 series (0235.200HXP) exhibits the lowest melting I²t (0.00867), indicating faster thermal response. Eaton products show melting I²t of 0.016. These variations remain within acceptable substitution parameters but should be cross-referenced against circuit protection requirements.

Inventory Availability: All substitute parts maintain active stock levels ranging from 665 to 1779 pieces, ensuring supply reliability for production and maintenance applications.

Frequently Asked Questions (FAQ)

Q: Can I use any of these substitute parts interchangeably with the 5SF 200-R?

A: Yes. All listed parts meet the critical substitution parameters: 200 mA current rating, 250 V AC voltage rating, 5mm x 20mm package dimensions, fast-blow response time, and 35A breaking capacity. Physical installation in existing fuse holders is compatible across all equivalents.

Q: What is the significance of DC cold resistance variation among substitutes?

A: DC cold resistance affects circuit behavior during normal operation. The original 5SF 200-R has 1.1 Ohms resistance. Littelfuse 217 series maintains 1.7 Ohms, while Eaton products exhibit 6.8 Ohms. For circuits where fuse resistance contributes to voltage drop or heat dissipation, select parts with resistance values closest to your design specification.

Q: Why do melting I²t values differ across substitutes?

A: Melting I²t represents the thermal energy required to melt the fuse element. Lower values indicate faster thermal response to overcurrent conditions. Littelfuse 235 series (0.00867) responds faster than Littelfuse 217 series (0.02) or Eaton products (0.016). Select based on your circuit's overcurrent protection timing requirements.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts carry RoHS3 compliance certification, meeting environmental and material restriction requirements for modern electronics manufacturing.

Q: Which substitute offers the broadest regulatory approval coverage?

A: Littelfuse 217 series parts (0217.200MXP, 0217.200TXP, 0217.200VXP, 0217.200HXP) provide the most comprehensive approval portfolio including CCC, CE, CSA, K-MARK, SEMKO, UL, and VDE certifications, suitable for global market applications.

Q: Can I substitute a part with different approval agencies than the original?

A: Substitution is permissible when the replacement part carries certifications required by your specific application or market. Verify that the substitute's approval agencies align with your system's regulatory requirements before implementation.

Q: What is the difference between direct and similar substitute classifications?

A: Direct substitutes (0034.1509, 0217.200MXBP, 0217.200MXP, 0217.200TXP, 0217.200VXP, BK/S500-200-R) are functionally equivalent across all critical parameters. Similar substitutes (0217.200HXP, 0235.200HXP, GDB-200MA) meet the same electrical and mechanical specifications but may have minor variations in secondary characteristics such as melting I²t or resistance. Both categories are suitable for replacement.
