Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the GSA 1.6-R is determined by strict equivalence across the following critical parameters:

• Current Rating: 1.6 A (exact match required)
• Voltage Rating (AC): 250 V (exact match required)
• Fuse Type: Cartridge, Ceramic (exact match required)
• Response Time: Slow Blow (exact match required)
• Package / Case: 3AB, 3AG, 1/4" x 1-1/4" (exact match required)
• Breaking Capacity @ Rated Voltage: 100 A (exact match required)
• Operating Temperature Range: -55°C ~ 125°C (exact match required)
• Size / Dimension: 0.250" Dia x 1.252" L (6.35mm x 31.80mm) (exact match required)

The TCA-1.6A manufactured by OptiFuse meets all substitution criteria and qualifies as a parametric equivalent for the GSA 1.6-R.

Parameter Comparison

Engineering Selection Recommendations

Both the GSA 1.6-R and TCA-1.6A maintain active product status with full regulatory compliance. The GSA 1.6-R carries approvals from CE, CSA, cULus, and PSE. The TCA-1.6A carries cULus and UL 248 approvals. Selection between these parts should be based on specific regulatory requirements applicable to the end application and regional compliance mandates. Both components satisfy ROHS3 compliance requirements and are suitable for industrial and commercial overcurrent protection applications within the specified operating temperature range of -55°C to 125°C.

Frequently Asked Questions (FAQ)

Q: Can the TCA-1.6A be used as a direct replacement for the GSA 1.6-R?

A: Yes. The TCA-1.6A meets all critical electrical and mechanical parameters required for substitution, including current rating, voltage rating, fuse type, response time, package configuration, breaking capacity, operating temperature range, and physical dimensions.

Q: Are there any differences in regulatory approvals between these parts?

A: The GSA 1.6-R carries CE, CSA, cULus, and PSE approvals. The TCA-1.6A carries cULus and UL 248 approvals. Verify that the substitute part's approval certifications align with your application's regional and industry-specific compliance requirements.

Q: Do these fuses require a specific holder?

A: Both the GSA 1.6-R and TCA-1.6A require a holder compatible with 3AB and 3AG standards. The physical dimensions of 0.250" diameter by 1.252" length (6.35mm x 31.80mm) ensure mechanical compatibility with standard cartridge fuse holders designed for this form factor.

Q: What is the difference between the DC Cold Resistance values?

A: The GSA 1.6-R specifies a DC Cold Resistance of 0.155 Ohms. This parameter is not provided for the TCA-1.6A in the available technical data. Consult the manufacturer's detailed specifications if DC resistance characteristics are critical to your application.

Q: Are both parts RoHS compliant?

A: Yes. Both the GSA 1.6-R and TCA-1.6A are ROHS3 compliant and suitable for applications subject to RoHS directives.
