Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 0337005.PXS is determined by the following critical parameters:

• Current Rating: 5 A (exact match required)
• Voltage Rating - DC: 32 V (exact match required)
• Package / Case: Blade, Micro (exact match required)
• Operating Temperature Range: -40°C ~ 125°C (exact match required)
• Physical Dimensions: 0.567" L x 0.165" W x 0.417" H (exact match required)
• Melting I²t: 17 (exact match required)

Both identified substitute parts meet all critical electrical and mechanical parameters. Substitution is valid based on identical current rating, voltage rating, package type, thermal operating range, physical dimensions, and thermal characteristics.

Parameter Comparison

Engineering Selection Recommendations

The 0337005.PXS is obsolete and should be replaced with either 0337005.PX2S or 0337005.LXS for new designs and procurement. Both substitute parts are active products from Littelfuse Inc. and maintain full electrical and mechanical compatibility.

0337005.PX2S is designated as MICRO2™ series and represents the current generation equivalent. 0337005.LXS is part of the 337 series and provides an alternative active source. Both parts carry ROHS3 compliance and are suitable for automotive applications within the specified temperature and voltage parameters.

Selection between the two substitutes may be based on packaging format (bulk availability) and internal resistance specifications, though both satisfy the core functional requirements of the obsolete 0337005.PXS.

Frequently Asked Questions (FAQ)

Q: Can 0337005.PX2S and 0337005.LXS be used interchangeably with 0337005.PXS?

A: Yes. Both substitute parts match the critical electrical parameters (5A current rating, 32V DC voltage rating), thermal characteristics (melting I²t of 17), physical dimensions (0.567" L x 0.165" W x 0.417" H), and operating temperature range (-40°C ~ 125°C). All three parts use the Blade, Micro package and require a holder for mounting.

Q: What is the primary reason for substitution?

A: The 0337005.PXS is classified as obsolete. The substitute parts 0337005.PX2S and 0337005.LXS are active products with equivalent specifications and improved availability.

Q: Are there differences in internal resistance between the substitutes?

A: The 0337005.PXS and 0337005.LXS specify DC cold resistance as 17.4 mOhms. The 0337005.PX2S specifies 0.0174 Ohms (17.4 mOhms equivalent). All three parts are functionally equivalent for automotive fuse applications.

Q: Do all substitute parts meet compliance requirements?

A: Yes. All three parts are ROHS3 compliant and carry MSL rating of 1 (Unlimited). Both substitute parts maintain REACH Unaffected status.

Q: What packaging options are available?

A: The 0337005.PXS was supplied with standard packaging. The 0337005.PX2S is available in bulk packaging. The 0337005.LXS is available in bulk packaging. Packaging format should be confirmed based on procurement requirements.
