S500-16-R Glass Cartridge Fuse Equivalent & Substitute Parts

Part Overview

The S500-16-R is a 16 A, 250 V AC/DC glass cartridge fuse manufactured by Eaton - Electronics Division. This component is classified as obsolete product status. The S500-16-R requires a fuse holder for installation and operates as a fast-blow cartridge fuse in the 5mm x 20mm package format. Due to its obsolete classification, equivalent and substitute parts from active product lines are necessary for ongoing system maintenance and new design implementations.

Substitute Part Grouping Explanation

Substitute parts for the S500-16-R are qualified based on strict electrical and mechanical parameter alignment. The following parameters determine substitution eligibility:

Critical Matching Parameters:

  • Current Rating: 16 A (exact match required)
  • Voltage Rating (AC): 250 V (exact match required)
  • Fuse Type: Cartridge, Glass (exact match required)
  • Response Time: Fast Blow (exact match required)
  • Package / Case: 5mm x 20mm (exact match required)
  • Mounting Type: Requires Holder (exact match required)

All substitute parts listed below meet these critical parameters. Substitute parts may differ in manufacturer, product status, compliance certifications, and operating temperature ranges, but maintain functional equivalence within the specified electrical and mechanical constraints.

Engineering Selection Recommendations

BK/GDB-16A (Eaton - Electronics Division): This substitute maintains manufacturer continuity with the original S500-16-R, both sourced from Eaton - Electronics Division. The BK/GDB-16A series is active product status and RoHS Compliant, providing a direct upgrade path from the obsolete S500-16-R. Selection of this part is appropriate for applications requiring Eaton product line consistency and RoHS compliance.

FSC-16A (OptiFuse): The FSC-16A is an active product with UL 248 approval agency certification and ROHS3 compliance. Operating temperature range is -55°C ~ 90°C. This part is suitable for applications requiring UL 248 certification and standard industrial temperature operating conditions.

FSD-16A (OptiFuse): The FSD-16A is an active product with IEC 60127 approval agency certification and ROHS3 compliance. Operating temperature range extends to -55°C ~ 125°C, providing broader thermal operating capability. This part is suitable for applications requiring IEC 60127 certification and extended high-temperature operation. REACH Unaffected status is documented.

Frequently Asked Questions (FAQ)

Q: Can the BK/GDB-16A directly replace the S500-16-R in existing applications?

A: Yes. The BK/GDB-16A meets all critical electrical and mechanical parameters: 16 A current rating, 250 V AC voltage rating, fast-blow response, cartridge glass fuse type, and 5mm x 20mm package dimensions. Both parts require a fuse holder for installation. The BK/GDB-16A is active product status, addressing the obsolescence of the S500-16-R.

Q: What is the difference between FSC-16A and FSD-16A?

A: Both parts are OptiFuse 16 A, 250 V AC/DC fast-blow glass cartridge fuses in 5mm x 20mm packages. The FSC-16A carries UL 248 certification with -55°C ~ 90°C operating temperature. The FSD-16A carries IEC 60127 certification with -55°C ~ 125°C operating temperature, providing extended high-temperature capability. Selection depends on required certification standard and operating temperature range.

Q: Are all substitute parts compatible with existing S500-16-R fuse holders?

A: Yes. All substitute parts maintain the 5mm x 20mm package dimensions and require a fuse holder for installation, identical to the S500-16-R. Physical compatibility with existing holder hardware is maintained.

Q: What compliance certifications are available across substitute options?

A: BK/GDB-16A provides RoHS Compliant status. FSC-16A provides UL 248 certification and ROHS3 compliance. FSD-16A provides IEC 60127 certification, ROHS3 compliance, and REACH Unaffected status. Selection should align with application compliance requirements.

Q: Why is the S500-16-R classified as obsolete?

A: The S500-16-R is obsolete product status. Active equivalent products from both Eaton (BK/GDB-16A) and OptiFuse (FSC-16A, FSD-16A) are available to support ongoing system requirements and new designs.
