Key Parameters

Substitute Part Grouping Explanation

Substitution of the SPP-4B200 is based on the following critical electrical and mechanical parameters:

• Current Rating: 200A (must match exactly)
• Voltage Rating: 700V AC (must match exactly)
• Manufacturer: Eaton - Bussmann Electrical Division (same manufacturer ensures design compatibility)
• Mounting compatibility: The substitute must accommodate the electrical system's installation requirements
• Regulatory compliance: REACH and ECCN classifications must align with the original specification

The identified substitute, 170M3615, maintains the same current and voltage ratings while offering an active product status. Both components share the same HTSUS classification and regulatory framework, confirming their functional equivalence within the specified electrical parameters.

Parameter Comparison

Engineering Selection Recommendations

The 170M3615 serves as the direct electrical equivalent to the obsolete SPP-4B200, matching the critical 200A / 700V specifications. The substitute is manufactured by the same supplier, ensuring design and performance consistency.

Key selection factors:

• The 170M3615 maintains active product status, ensuring long-term availability and supply chain continuity
• Both components share identical HTSUS and ECCN classifications, confirming regulatory alignment
• The 170M3615 is RoHS Compliant, meeting current environmental standards
• Mounting configuration differs (bolt mount versus blade holder requirement); system integration must account for this mechanical difference
• The substitute provides documented breaking capacity (200kA) and melting I²t (2200), supporting design verification

Frequently Asked Questions (FAQ)

Q: Can the 170M3615 directly replace the SPP-4B200 without modification?

A: Both components share identical electrical ratings (200A, 700V AC). However, the mounting type differs: SPP-4B200 requires a dedicated holder, while 170M3615 uses bolt mount. System integration must accommodate this mechanical difference.

Q: Why is the SPP-4B200 listed as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The 170M3615 is the active equivalent, ensuring continued availability for new designs and system replacements.

Q: Are there compliance differences between the two parts?

A: Both components share the same ECCN (EAR99) and HTSUS (8536.10.0040) classifications. The 170M3615 is RoHS Compliant, meeting current environmental requirements.

Q: What is the significance of the 200kA breaking capacity specification?

A: Breaking capacity defines the maximum fault current the fuse can safely interrupt at rated voltage. The 170M3615 specification of 200kA at rated voltage confirms its ability to protect circuits under fault conditions.

Q: How do the melting I²t values affect substitution?

A: Melting I²t (2200 for the 170M3615) characterizes the fuse's thermal response. This parameter must be verified against circuit protection requirements to ensure proper coordination with upstream protective devices.

Q: What packaging considerations apply to the 170M3615?

A: The 170M3615 is supplied in bulk packaging. Verify that procurement quantities and handling procedures align with system assembly and inventory management requirements.
