SPP-7H900 Equivalent & Substitute Parts

Part Overview

The SPP-7H900 is a fuse link manufactured by Eaton - Bussmann Electrical Division, rated for 900A at 700V operation. This component is classified as obsolete, requiring identification of active equivalent parts for continued system support and procurement. The fuse link design necessitates a compatible holder for installation, making substitute selection dependent on matching electrical ratings and mounting interface requirements.

Key Parameters

Substitute Part Grouping Explanation

The 170M6763 qualifies as a functional substitute based on matching electrical parameters: both components are rated for 900A current and 700V AC voltage operation, establishing electrical compatibility. The substitute maintains the same manufacturer source (Eaton - Bussmann Electrical Division) and HTSUS classification (8536.10.0040), confirming product category alignment.

Key substitution parameters:

• Current Rating: 900A (matched)
• Voltage Rating: 700V AC (matched)
• Manufacturer: Eaton - Bussmann Electrical Division (same source)
• ECCN Classification: EAR99 (matched)

The primary distinction lies in mounting configuration: the SPP-7H900 uses a fuse link design requiring external holder installation, while the 170M6763 employs bolt mount architecture with rectangular blade package geometry. This difference necessitates mechanical interface verification during integration.

Parameter Comparison

Engineering Selection Recommendations

The 170M6763 is an active product with current manufacturing status, addressing the obsolescence of the SPP-7H900. Both components share identical electrical ratings (900A, 700V AC) and regulatory classification (EAR99, HTSUS 8536.10.0040), establishing direct functional equivalence for circuit protection applications.

The 170M6763 provides additional documented specifications including breaking capacity (200kA) and melting I²t (100000), supporting detailed fault analysis and system coordination calculations. RoHS compliance status of the substitute aligns with current environmental regulations.

Mechanical integration requires verification: the transition from fuse link holder-dependent design to bolt mount configuration necessitates mechanical interface assessment within the target installation environment. Dimensional specifications for the 170M6763 (2.008" L x 2.992" W x 3.622" H) should be confirmed against available mounting space and bolt pattern compatibility.

Frequently Asked Questions (FAQ)

Q: Can the 170M6763 directly replace the SPP-7H900 in existing installations?

A: Electrical compatibility is confirmed through matched 900A and 700V ratings. Mechanical compatibility depends on mounting interface: the SPP-7H900 requires a separate holder, while the 170M6763 uses bolt mount architecture. Physical installation feasibility must be verified against existing mounting provisions.

Q: What are the critical parameters for substitution between these fuses?

A: Current rating (900A), voltage rating (700V AC), and manufacturer source (Eaton - Bussmann Electrical Division) are the primary electrical substitution criteria. Mounting type and package configuration are secondary mechanical considerations that do not affect electrical function but require installation verification.

Q: Why is the SPP-7H900 listed as obsolete?

A: Obsolete status indicates discontinued manufacturing. The 170M6763 represents the active equivalent product line from the same manufacturer, providing continued availability for 900A/700V circuit protection applications.

Q: Are there regulatory or compliance differences between these parts?

A: Both components share identical ECCN (EAR99) and HTSUS (8536.10.0040) classifications. The 170M6763 carries RoHS compliance certification, reflecting current environmental standards. REACH status for the substitute is not specified in available documentation.

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 170M6763 specification of 200kA at rated voltage establishes the maximum system fault level for which this component provides protection. This parameter was not specified for the obsolete SPP-7H900.
