SPP-7F1250 Equivalent & Substitute Parts

Part Overview

The SPP-7F1250 is a fuse link manufactured by Eaton - Bussmann Electrical Division, rated for 1.25kA at 700V. This component is classified as obsolete and requires a holder for installation. Due to its obsolete status, identifying functionally equivalent substitute parts is essential for system maintenance, repair, and continued operation in electrical and industrial applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SPP-7F1250 is based on matching the following critical electrical and mechanical parameters:

• Current Rating: 1.25kA
• Voltage Rating: 700V AC
• Manufacturer: Eaton - Bussmann Electrical Division
• Regulatory Compliance: REACH Unaffected, EAR99 classification

The substitute part 170M6716 meets these core requirements. While it differs in mounting type (bolt mount versus holder-based installation) and physical form factor (rectangular blade versus fuse link), it maintains electrical equivalence in current and voltage ratings. The difference in mounting configuration requires mechanical integration assessment during installation.

Parameter Comparison

Engineering Selection Recommendations

The 170M6716 is the designated substitute for the obsolete SPP-7F1250 based on electrical parameter equivalence. Both components share identical current (1.25kA) and voltage (700V) ratings and are manufactured by the same supplier. The 170M6716 holds active product status, ensuring availability and continued support.

Key considerations for selection:

• The 170M6716 is RoHS Compliant, whereas RoHS status for the SPP-7F1250 is not specified.
• Both components carry EAR99 export classification and fall under the same HTSUS tariff code.
• The 170M6716 provides documented breaking capacity (200kA) and melting I²t (290000), offering additional performance transparency.
• Mechanical integration differs: the SPP-7F1250 requires a holder assembly, while the 170M6716 uses bolt mount configuration. System redesign or adapter solutions may be necessary.

Frequently Asked Questions (FAQ)

Q: Can the 170M6716 directly replace the SPP-7F1250 without modification?

A: Both components are electrically equivalent at 1.25kA and 700V. However, the mounting configuration differs (holder-based versus bolt mount). Direct replacement requires mechanical compatibility assessment of the installation location.

Q: What is the significance of the SPP-7F1250 being obsolete?

A: Obsolete status indicates the manufacturer no longer produces this component. The 170M6716 substitute is actively manufactured, ensuring long-term availability for procurement and inventory planning.

Q: Are there compliance differences between these parts?

A: Both components share identical ECCN (EAR99) and HTSUS (8536.10.0040) classifications. The 170M6716 is RoHS Compliant; RoHS status for the SPP-7F1250 is not documented.

Q: What do the breaking capacity and melting I²t values indicate?

A: Breaking capacity (200kA) specifies the maximum fault current the 170M6716 can safely interrupt at rated voltage. Melting I²t (290000) characterizes the thermal energy required to melt the fuse element, affecting response time and protection characteristics.

Q: Does the difference in package type affect electrical performance?

A: No. The package difference (Fuse Link versus Rectangular Blade) reflects form factor and mounting method only. Electrical performance at rated current and voltage remains equivalent.
