The substitute part 0314.375HXP manufactured by Littelfuse Inc. meets all critical electrical, mechanical, and compliance requirements for direct substitution with the ABC-3/8-R.

Parameter Comparison

Engineering Selection Recommendations

Both the ABC-3/8-R and 0314.375HXP maintain active product status and satisfy identical electrical and mechanical specifications. Selection between these parts is based on the following engineering considerations:

ABC-3/8-R (Eaton - Electronics Division):

• Current inventory: 989 units
• Certifications: CSA, UL
• Established supply chain for Eaton-standardized designs

0314.375HXP (Littelfuse Inc.):

• Current inventory: 935 units
• Certifications: CE, CSA, UL (includes CE marking)
• Additional technical data available: Breaking Capacity (35A AC, 10kA DC), Melting I²t (0.05), DC Cold Resistance (0.82 Ohms), Operating Temperature (-55°C ~ 125°C)
• REACH Status: REACH Unaffected
• Moisture Sensitivity Level: 1 (Unlimited)

Both parts are ROHS3 compliant and classified under identical ECCN (EAR99) and HTSUS (8536.10.0040) codes. Selection should be based on existing design standards, supply chain preferences, and regional certification requirements.

Frequently Asked Questions (FAQ)

Q: Can the 0314.375HXP directly replace the ABC-3/8-R in existing designs?

A: Yes. Both parts are electrically and mechanically equivalent across all critical parameters: 375 mA current rating, 250 V AC / 125 V DC voltage ratings, fast-blow response, ceramic cartridge construction, and 3AB/3AG holder compatibility with identical 0.250" Dia x 1.250" L dimensions.

Q: Are there any holder compatibility differences between these fuses?

A: No. Both the ABC-3/8-R and 0314.375HXP are designed for 3AB, 3AG, and 1/4" x 1-1/4" holder configurations with identical physical dimensions (6.35mm x 31.75mm). No holder modifications are required for substitution.

Q: What certifications apply to each part?

A: The ABC-3/8-R carries CSA and UL certifications. The 0314.375HXP carries CE, CSA, and UL certifications. Both parts are ROHS3 compliant. Applications requiring CE marking should specify the 0314.375HXP.

Q: Are both parts currently available?

A: Yes. The ABC-3/8-R has 989 units in inventory. The 0314.375HXP has 935 units in inventory. Both maintain active product status.

Q: What is the difference in operating temperature range?

A: The ABC-3/8-R does not specify an operating temperature range in the provided data. The 0314.375HXP specifies -55°C ~ 125°C. For applications with defined temperature requirements, the 0314.375HXP provides documented thermal performance.

Q: Can these parts be used interchangeably in the same circuit?

A: Yes. Identical electrical ratings (375 mA, 250 V AC, 125 V DC), response time (fast-blow), and mechanical form factor ensure functional interchangeability in any application designed for either part number.
