Substitute Part Grouping Explanation

Substitution eligibility for the 0603SFS150F/32-2 is determined by strict equivalence across the following parameters:

  • Current Rating: 1.5 A (exact match required)
  • Voltage Rating (DC): 32 V (exact match required)
  • Response Time: Slow Blow (exact match required)
  • Package / Case: 0603 (1608 Metric) (exact match required)
  • Mounting Type: Surface Mount (exact match required)
  • Fuse Type: Board Mount (Cartridge Style Excluded) (exact match required)
  • Breaking Capacity @ Rated Voltage: 50A (exact match required)

Two substitute parts meet these criteria and are available as active alternatives:

  1. 0ABB-1500-TM (Bel Fuse Inc.) - Direct manufacturer equivalent with Active product status
  2. SF-0603SP150M-2 (Bourns Inc.) - Manufacturer recommended equivalent with Active product status

Engineering Selection Recommendations

Both substitute parts satisfy the electrical and mechanical requirements for direct replacement of the 0603SFS150F/32-2. Selection between alternatives should be based on the following factors:

0ABB-1500-TM (Bel Fuse Inc.):

  • Active product status with current manufacturing support
  • AEC-Q200 and cURus certifications provide automotive and regulatory compliance
  • Extended operating temperature range to 150°C
  • Tape & Reel packaging available

SF-0603SP150M-2 (Bourns Inc.):

  • Active product status with current manufacturing support
  • Extended operating temperature range to 150°C
  • Tape & Reel packaging available
  • Part of the SinglFuse™ SF-0603SPxxxM series

Both parts are ROHS3 compliant and maintain MSL 1 (Unlimited) moisture sensitivity classification. The choice between these alternatives depends on supply chain availability, procurement agreements, and specific application certifications required.

Frequently Asked Questions (FAQ)

Q: Can the 0ABB-1500-TM or SF-0603SP150M-2 be used as direct replacements for the 0603SFS150F/32-2?

A: Yes. Both parts meet all critical electrical and mechanical parameters: 1.5A current rating, 32V DC voltage rating, slow blow response, 0603 package format, 50A breaking capacity, and surface mount configuration. They are electrically and mechanically interchangeable.

Q: What is the difference between the two substitute parts?

A: The primary differences are manufacturer identity and certifications. The 0ABB-1500-TM includes AEC-Q200 and cURus certifications, making it suitable for automotive applications. Both parts offer extended operating temperature ranges to 150°C compared to the original part's 125°C maximum. DC cold resistance values differ (150 Ohms for 0ABB-1500-TM versus 0.1 Ohms for SF-0603SP150M-2), but this does not affect substitution eligibility as both meet the 50A breaking capacity requirement.

Q: Why is the original 0603SFS150F/32-2 marked as Obsolete?

A: Obsolete status indicates that Littelfuse Inc. has discontinued manufacturing this part. Active equivalent alternatives from other manufacturers ensure continued availability for circuit protection applications requiring these specifications.

Q: Are packaging options consistent across all three parts?

A: The original 0603SFS150F/32-2 packaging is not specified in available data. Both substitute parts are available in Tape & Reel (TR) packaging, which is standard for surface mount 0603 fuses in production environments.

Q: Do all three parts comply with RoHS requirements?

A: Yes. The original part and both substitutes are ROHS3 compliant, meeting current environmental and hazardous substance restrictions.
