Key Parameters

Substitute Part Grouping Explanation

Substitute selection is based exclusively on critical electrical and mechanical parameters: current rating, voltage rating, and mounting type. Only those models from the same manufacturer with matching current and voltage specifications and compatible mounting requirements are considered viable substitutes. The substitute part must also have matching regulatory compliance, packaging style, and inventory status where specified.

Parameter Comparison

Engineering Selection Recommendations

The SPP-7M900 is currently obsolete, while the substitute 170M6563 is active with comparable electrical specifications. Both parts share the same manufacturer, current rating, voltage rating, and regulatory codes, supporting direct substitution strictly based on these matching parameters. The substitute 170M6563 is RoHS compliant and carries applicable certification (CSA, UR) as specified.

Frequently Asked Questions (FAQ)

Q1: What criteria must be met for a fuse link to be considered a direct substitute?

A fuse link can be considered a direct substitute when it matches the original's current rating, voltage rating, mounting type (requires holder), and regulatory compliance parameters.

Q2: Are there differences in package or case styles to consider with substitute parts?

Yes. The main part SPP-7M900 uses a fuse link style, while the substitute 170M6563 specifies a rectangular, blade package. Selection must ensure mechanical compatibility with holder requirements.

Q3: Is the substitute part certified to the same regulatory standards?

Both parts share ECCN EAR99 and HTSUS 8536.10.0040. The substitute also specifies CSA, UR certification and RoHS compliance.

Q4: How does product status affect part selection in this fuse link category?

Obsolete status necessitates substitution by an active, in-stock model with equivalent electrical and mechanical specifications from the same manufacturer.

Q5: What mounting requirements do both parts share?

Both SPP-7M900 and 170M6563 require a holder for correct installation and operation. This must be verified using only the data provided in the specifications.
