Substitute Part Grouping Explanation

Substitution eligibility for the 0337015.PXS is determined by strict equivalence across the following critical parameters:

• Current Rating: 15 A (exact match required)
• Voltage Rating - DC: 32 V (exact match required)
• Package / Case: Blade, Micro (exact match required)
• Physical Dimensions: 0.567" L x 0.165" W x 0.417" H (exact match required)
• Operating Temperature Range: -40°C ~ 125°C (exact match required)
• Melting I²t: 189 (exact match required)

Two substitute parts meet these criteria and are manufactured by Littelfuse Inc.:

1. 0337015.PX2S - Direct manufacturer substitute, MICRO2™ series, active product status
2. 0337015.LXS - Parametric equivalent, 337 series, active product status

Both substitutes maintain identical electrical and mechanical specifications to the original part, ensuring functional interchangeability within automotive fuse holder applications.

Parameter Comparison

Engineering Selection Recommendations

Both 0337015.PX2S and 0337015.LXS are active products suitable for replacing the obsolete 0337015.PXS in automotive fuse applications. Selection between the two substitutes should be based on availability and procurement requirements:

• 0337015.PX2S represents the current generation MICRO2™ series offering from Littelfuse Inc., with higher inventory availability (3045 units) and bulk packaging options.
• 0337015.LXS maintains the original 337 series designation with equivalent electrical and mechanical performance, offering 1151 units in stock.

Both parts carry ROHS3 compliance and identical electrical ratings. The 0337015.LXS additionally carries REACH Unaffected status. Physical dimensions, thermal operating range, and fuse characteristics remain identical across all three part numbers, ensuring direct functional substitution within existing automotive fuse holder assemblies.

Frequently Asked Questions (FAQ)

Q: Can 0337015.PX2S and 0337015.LXS be used interchangeably with 0337015.PXS?

A: Yes. Both substitute parts maintain identical current ratings (15A), voltage ratings (32V DC), physical dimensions (0.567" L x 0.165" W x 0.417" H), melting I²t values (189), and operating temperature ranges (-40°C ~ 125°C). They are mechanically and electrically equivalent for automotive fuse holder applications.

Q: Why is the original 0337015.PXS listed as obsolete?

A: Product obsolescence reflects Littelfuse Inc.'s manufacturing and product line decisions. The active substitutes 0337015.PX2S and 0337015.LXS provide equivalent functionality and are recommended for new procurement and system support.

Q: Are there differences in DC cold resistance between the substitutes?

A: The 0337015.PXS and 0337015.LXS both specify 4.9 Ohms DC cold resistance. The 0337015.PX2S specifies 0.0049 Ohms. This difference does not affect substitution eligibility, as DC cold resistance is not a critical parameter for automotive fuse selection in this application category.

Q: Do all three parts require the same fuse holder?

A: Yes. All three parts share identical blade micro form factor specifications and mounting requirements. They are compatible with the same automotive fuse holder assemblies.

Q: What compliance certifications apply to these parts?

A: All three parts are ROHS3 compliant. The 0337015.LXS and 0337015.PX2S additionally carry REACH Unaffected status. All parts are classified under ECCN EAR99 and HTSUS 8536.10.0040.
