Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 169.5601 is determined by strict equivalence across the following critical parameters:

• Current Rating: 60 A (exact match required)
• Voltage Rating - DC: 32 V (exact match required)
• Fuse Type: Automotive (exact match required)
• Response Time: Slow Blow (exact match required)
• Package / Case: Blade, Max (exact match required)
• Mounting Type: Requires Holder (exact match required)

The substitute part 0299060.TXN meets all mandatory electrical and mechanical criteria for direct substitution. Both parts are manufactured by Littelfuse Inc. and maintain identical functional specifications within the automotive fuse category.

The 0299060.TXN offers the additional advantage of active product status and ROHS3 compliance, making it suitable for new designs and applications subject to environmental regulations. The substitute part is manufactured under the MAXI® series designation and carries DIN, ISO, and SAE approvals, supporting its use in regulated automotive applications.

Frequently Asked Questions (FAQ)

Q: Can the 0299060.TXN be used as a direct replacement for the 169.5601?

A: Yes. Both parts are 60A, 32VDC automotive blade fuses with slow-blow response, identical package dimensions, and holder-mount requirements. Electrical and mechanical specifications are equivalent.

Q: What is the primary difference between these parts?

A: The 169.5601 is obsolete, while the 0299060.TXN is active. The substitute part carries ROHS3 compliance and formal approvals (DIN, ISO, SAE), whereas the original part is RoHS non-compliant.

Q: Are there dimensional differences between the parts?

A: Dimensions are nominally equivalent. The 169.5601 measures 1.169" L × 0.358" W × 0.839" H, while the 0299060.TXN measures 1.150" L × 0.348" W × 0.850" H. These minor variations remain within the Blade, Max package specification and do not affect holder compatibility.

Q: What certifications does the substitute part carry?

A: The 0299060.TXN is certified to DIN, ISO, and SAE standards and is ROHS3 compliant. The original 169.5601 carries no listed approval agencies.

Q: Can both parts be used interchangeably in existing designs?

A: Yes, provided the application uses a standard automotive Max blade fuse holder. The electrical ratings, response characteristics, and physical form factors are equivalent.
