Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 169.6885.5352 is determined by strict equivalence across the following critical electrical and mechanical parameters:

• Current Rating: 35 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)
• Breaking Capacity @ Rated Voltage: 1kA (exact match required)

The substitute part 0299035.ZXNV meets all mandatory electrical and mechanical criteria for direct substitution. Both components are manufactured by Littelfuse Inc. and maintain identical functional specifications within the automotive fuse category.

Parameter Comparison

Engineering Selection Recommendations

• Electrical Equivalence: Identical current rating (35 A), voltage rating (32 V), and breaking capacity (1kA)
• Mechanical Compatibility: Identical blade-type package and holder requirements
• Functional Equivalence: Matching slow-blow response characteristics for automotive circuit protection
• Compliance Status: Both components maintain ROHS3 compliance; the substitute part is active and readily available
• Manufacturer Continuity: Both parts are manufactured by Littelfuse Inc., ensuring consistent design and quality standards

The substitute part 0299035.ZXNV is suitable for direct replacement in all applications where the 169.6885.5352 was originally specified.

Frequently Asked Questions (FAQ)

Q: Can the 0299035.ZXNV be used as a direct replacement for the 169.6885.5352?

A: Yes. Both components share identical electrical ratings (35 A, 32 V DC), fuse type (automotive), response time (slow blow), package configuration (blade, max), and breaking capacity (1kA). The substitute part is mechanically and functionally equivalent.

Q: What is the difference in melting I²t between the two parts?

A: The main part specifies 8400 A²s while the substitute specifies 6032 A²s. Both values fall within the acceptable range for 35 A slow-blow automotive fuses and do not affect substitution eligibility, as the critical parameters (current rating, voltage, response time, and package) remain identical.

Q: Are there any physical dimension differences between these parts?

A: Minor dimensional variations exist. The 169.6885.5352 measures 1.169" L x 0.358" W x 0.839" H (29.70mm x 9.10mm x 21.30mm), while the 0299035.ZXNV measures 1.150" L x 0.348" W x 0.850" H (29.21mm x 8.85mm x 21.59mm). Both conform to the Blade, Max package specification and are compatible with standard automotive fuse holders designed for this package type.

Q: What is the availability status of the substitute part?

A: The 0299035.ZXNV is classified as active with 13,193 pieces in stock, compared to the obsolete status of the 169.6885.5352. This ensures reliable supply chain availability for current and future applications.

Q: Are both parts RoHS compliant?

A: Yes. Both the 169.6885.5352 and 0299035.ZXNV maintain ROHS3 compliance, meeting environmental and regulatory requirements for automotive applications.
