Key Parameters

Substitute Part Grouping Explanation

Substitute selection for fuse links is determined strictly by matching the electrical and mechanical parameters provided. Only parts with identical current rating, voltage rating, and mounting compatibility are considered. The SPP-4B250 main part is obsolete, thus the substitutes listed must have the same current rating (250A), equivalent voltage rating (700V AC), mounting compatibility, and packaging/category alignment. Only parameters explicitly provided in the input define substitute suitability.

Parameter Comparison

Engineering Selection Recommendations

SPP-4B250 is classified as obsolete, while 170M3616 is active and currently available. Both share identical current and voltage ratings and are under the same ECCN and HTSUS classification. SPP-4B250 has an MSL of 1 (Unlimited), whereas 170M3616 lists MSL as Not Applicable, which does not restrict selection based on the provided categories. Compliance with EAR99 ensures proper export and trade classification for both parts.

Frequently Asked Questions (FAQ)

Q1: What determines compatibility between SPP-4B250 and 170M3616 fuse links?
Compatibility is determined by matching electrical specifications such as current rating (250A) and voltage rating (700V AC), mounting method, and packaging format as provided.

Q2: Can substitute part 170M3616 be used directly in place of SPP-4B250?
Substitution is based on identical current and voltage ratings. Mounting method and package/case should align with system requirements as per provided data.

Q3: Does the change in part status between obsolete and active affect selection?
Obsolete status of SPP-4B250 indicates the need to use substitutes like 170M3616, which is active and stocked, to ensure ongoing support and replacement.

Q4: Are MSL and compliance status relevant for choosing between these fuse links?
Both parts carry ECCN EAR99 and have unrestricted MSL, meeting compliance requirements per the provided classifications.

Q5: What package or mounting considerations should be observed?
Only the mounting type and package/case fields provided should be compared to verify physical compatibility. The substitute part must match the required form factor and installation method.
