Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 0312.100MXCCP are qualified based on the following critical parameters:

• Current Rating: 100 mA (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: 3AB, 3AG, 1/4" x 1-1/4" (exact match required for holder compatibility)
• Breaking Capacity @ Rated Voltage: 35 A (exact match required)
• Size / Dimension: 0.250" Dia x 1.250" L (exact match required)
• Operating Temperature Range: -55°C ~ 125°C (exact match required)

All substitute parts listed maintain these critical parameters, ensuring mechanical and electrical interchangeability within 3AB and 3AG holder assemblies.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain identical electrical and mechanical specifications to the 0312.100MXCCP. Selection among these parts is based on the following factors:

Littelfuse 0312.100MXP and 0312.100VXP: These parts are direct Littelfuse series equivalents with identical specifications and full CE, CSA, and UL certifications. The 0312.100MXP offers the highest inventory availability at 2501 units.

Eaton AGC-1/10-R and BK/AGC-1/10-R: These parts are cross-manufacturer equivalents from Eaton's AGC series. Both maintain CSA and UL certifications. The BK/AGC-1/10-R carries ROHS3 compliance matching the main part, while AGC-1/10-R carries standard RoHS compliance. Both are suitable for applications requiring multi-source qualification.

All parts are active in production and suitable for direct substitution in 3AB and 3AG holder assemblies.

Frequently Asked Questions (FAQ)

Q: Can the 0312.100MXP be used as a direct replacement for the 0312.100MXCCP?

A: Yes. Both parts share identical current rating (100 mA), voltage rating (250 V AC), fuse type (cartridge, glass), response time (fast blow), package dimensions (3AB, 3AG, 1/4" x 1-1/4"), breaking capacity (35 A), and operating temperature range (-55°C ~ 125°C). They are functionally interchangeable in 3AB and 3AG holder applications.

Q: What is the difference between Littelfuse and Eaton substitute parts?

A: The Littelfuse parts (0312.100MXP, 0312.100VXP) are from the same manufacturer as the main part and carry CE certification in addition to CSA and UL. The Eaton parts (AGC-1/10-R, BK/AGC-1/10-R) are from a different manufacturer but maintain identical electrical and mechanical specifications with CSA and UL certifications. Selection depends on supply chain requirements and multi-source qualification needs.

Q: Are the Eaton AGC-1/10-R and BK/AGC-1/10-R interchangeable?

A: Yes. Both parts are identical in electrical and mechanical specifications. The primary difference is RoHS compliance status: BK/AGC-1/10-R is ROHS3 compliant, while AGC-1/10-R carries standard RoHS compliance. Selection depends on specific environmental or regulatory requirements.

Q: What holder types are compatible with these fuses?

A: All listed parts are designed for 3AB and 3AG holder assemblies with 1/4" x 1-1/4" (6.35mm x 31.75mm) dimensions. Verify holder compatibility before installation.

Q: Can these 100 mA fuses be used in applications rated for higher current?

A: No. The 100 mA current rating is the maximum design specification. Using these fuses in applications requiring higher current ratings will result in nuisance blowing and circuit protection failure.
