Key Parameters

Substitute Part Grouping Explanation

The 0337010.LXS is identified as a parametric equivalent to the 0337010.PX2S based on the following critical parameters:

• Current Rating: Both parts are rated at 10 A
• Voltage Rating - DC: Both parts are rated at 32 V
• Fuse Type: Both are automotive fuses
• Package / Case: Both use Blade, Micro form factor
• Melting I²t: Both have a melting I²t value of 89
• Operating Temperature Range: Both operate from -40°C to 125°C
• Size / Dimension: Both share identical physical dimensions (0.567" L x 0.165" W x 0.417" H)
• RoHS Status: Both are ROHS3 Compliant
• Mounting Type: Both require a holder for installation

These parameters define the substitution criteria for automotive micro blade fuses in this current and voltage class.

Frequently Asked Questions (FAQ)

Q: Can the 0337010.LXS be used as a direct replacement for the 0337010.PX2S?

A: Yes. Both parts share identical current rating (10 A), voltage rating (32 V DC), package type (Blade, Micro), melting I²t (89), operating temperature range (-40°C to 125°C), and physical dimensions. They are functionally interchangeable in automotive fuse holder applications.

Q: Are there any differences in breaking capacity between these parts?

A: The 0337010.PX2S does not specify a breaking capacity value. The 0337010.LXS specifies a breaking capacity of 1 kA at rated voltage. This difference does not affect substitution eligibility based on the provided parameters.

Q: What is the significance of the DC Cold Resistance difference?

A: The 0337010.PX2S has a DC Cold Resistance of 0.0078 Ohms, while the 0337010.LXS has 7.8 Ohms. This parameter was not identified as a substitution criterion and does not prevent functional equivalence for automotive fuse applications.

Q: Do both parts require the same holder type?

A: Yes. Both parts are Blade, Micro form factor fuses that require a compatible micro blade fuse holder for installation.

Q: Are both parts compliant with automotive and environmental standards?

A: Yes. Both parts are ROHS3 compliant and REACH unaffected, meeting current automotive and environmental regulatory requirements.
