Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the GSA10 are identified from the Littelfuse Inc. 326 series ceramic fuse cartridge line. Substitution is based on the following critical parameters:

• Current Rating: 10 A
• Voltage Rating (AC): 250 V
• Fuse Type: Cartridge, Ceramic
• Response Time: Slow Blow (Time Delay)
• Package / Case: 3AB, 3AG, 1/4" x 1-1/4"
• Mounting Type: Requires Holder
• RoHS Compliance: ROHS3 Compliant
• ECCN Classification: EAR99
• HTSUS Code: 8536.10.0040

All three substitute parts (0326010.HXP, 0326010.MXP, 0326010.VXP) share identical electrical and mechanical specifications with the GSA10, differing only in packaging format (Bulk vs. Box) and internal construction variants.

Parameter Comparison

Engineering Selection Recommendations

All three Littelfuse 326 series substitutes maintain Active product status and ROHS3 compliance, matching the GSA10 specification. Selection among 0326010.HXP, 0326010.MXP, and 0326010.VXP is determined by inventory availability and packaging requirements:

• 0326010.MXP offers the highest inventory level (16029 Pcs) for applications requiring bulk quantities
• 0326010.HXP provides 1853 Pcs with CE, CSA, K-MARK, PSE, and UL certifications
• 0326010.VXP provides 798 Pcs with CE, CSA, KC, PSE, and UL certifications

All three parts share identical electrical characteristics, thermal operating range (-55°C ~ 125°C), and mechanical dimensions. Approval agency certifications differ slightly; selection should align with regional regulatory requirements.

Frequently Asked Questions (FAQ)

Q: What determines if a fuse can substitute for the GSA10?

A: Substitution is based on matching current rating (10 A), voltage rating (250 V AC), fuse type (ceramic cartridge), response time (slow blow/time delay), and package dimensions (3AB, 3AG, 1/4" x 1-1/4"). All three Littelfuse parts meet these criteria.

Q: Are the Littelfuse 326 series parts mechanically compatible with GSA10 applications?

A: Yes. All substitute parts share identical package specifications (3AB, 3AG, 1/4" x 1-1/4") and require the same holder type. Physical dimensions are 0.250" diameter by 1.250" length.

Q: What is the difference between 0326010.HXP, 0326010.MXP, and 0326010.VXP?

A: These parts are functionally equivalent with identical electrical and thermal specifications. Differences exist in packaging format (all Bulk), internal construction variants, and approval agency certifications. 0326010.VXP includes KC certification in addition to other agencies.

Q: Do all substitute parts maintain ROHS3 compliance?

A: Yes. All three Littelfuse substitutes are ROHS3 compliant, matching the GSA10 environmental specification.

Q: What is the breaking capacity of these fuses?

A: All substitute parts have a breaking capacity of 400A at rated voltage (250V AC).

Q: Are there temperature operating range differences?

A: No. All substitute parts operate across the identical temperature range of -55°C to 125°C.
