Substitute Part Grouping Explanation

Substitute parts for the ABC-7-R are classified into two categories based on parametric equivalence:

Direct Manufacturer Equivalent: BK/ABC-7-R is an Eaton - Electronics Division part with identical electrical specifications, mechanical dimensions, response characteristics, and approval certifications to the ABC-7-R. This part differs only in packaging designation and inventory availability.

Parametric Equivalents: BK/GBB-7-R (Eaton - Electronics Division, GBB series) and the Littelfuse 314 series parts (0314007.HXP, 0314007.MXP, 0314007.VXP) share the following critical substitution parameters:

• Current Rating: 7 A
• Voltage Rating - AC: 250 V
• Voltage Rating - DC: 125 V
• Fuse Type: Cartridge, Ceramic
• Response Time: Fast Blow
• Package / Case: 3AB, 3AG, 1/4" x 1-1/4"
• Size / Dimension: 0.250" Dia x 1.250" L (6.35 mm x 31.75 mm)
• Mounting Type: Requires Holder
• RoHS Status: ROHS3 Compliant
• Product Status: Active

Substitution is valid when all critical parameters match. Variations in breaking capacity, melting I²t, DC cold resistance, operating temperature range, and approval agency certifications do not prevent functional substitution but reflect design differences between manufacturers.

Parameter Comparison

Engineering Selection Recommendations

BK/ABC-7-R (Eaton - Electronics Division): This direct manufacturer equivalent maintains identical electrical specifications, mechanical dimensions, and approval certifications (CSA, UL) to the ABC-7-R. Selection of this part is appropriate for applications requiring continuity with the original Eaton ABC series design and certification profile.

BK/GBB-7-R (Eaton - Electronics Division): This parametric equivalent from the Eaton GBB series matches all critical substitution parameters. The breaking capacity specification differs (10 kA versus 200 A AC, 10 kA DC for the ABC-7-R), and approval certifications include CSA and UR. This part is suitable for applications where GBB series compatibility is acceptable and the specified breaking capacity is adequate.

0314007.HXP, 0314007.MXP, 0314007.VXP (Littelfuse Inc., 314 Series): These parametric equivalents from Littelfuse match all critical substitution parameters and provide expanded approval certifications (CE, CSA, K-MARK, PSE, UL for HXP and MXP; CE, CSA, KC, PSE, UL for VXP). The 314 series fuses feature higher breaking capacity (750 A AC, 10 kA DC) and specified operating temperature range (-55°C ~ 125°C). These parts are suitable for applications requiring broader international certifications or extended temperature performance. The three variants (HXP, MXP, VXP) differ only in internal construction and are functionally equivalent for the specified electrical parameters.

All substitute parts are Active status products and ROHS3 compliant, ensuring regulatory alignment with the original ABC-7-R specification.

Frequently Asked Questions (FAQ)

Q: Can BK/ABC-7-R be used as a direct replacement for ABC-7-R?

A: Yes. BK/ABC-7-R is a direct manufacturer equivalent from Eaton - Electronics Division with identical electrical ratings (7 A, 250 V AC, 125 V DC), mechanical dimensions (0.250" Dia x 1.250" L), response time (Fast Blow), package designation (3AB, 3AG), and approval certifications (CSA, UL). The parts are functionally interchangeable.

Q: What is the difference between the Eaton ABC-7-R and the Littelfuse 0314007 series fuses?

A: Both product families meet the critical substitution parameters: 7 A current rating, 250 V AC / 125 V DC voltage ratings, ceramic cartridge construction, fast-blow response, and 3AB/3AG package compatibility. Differences include manufacturer (Eaton versus Littelfuse), breaking capacity (200 A AC for ABC-7-R versus 750 A AC for Littelfuse 314 series), melting I²t values (109.33 versus 71), DC cold resistance (0.016 Ohms versus 0.0187 Ohms), and approval certifications. The Littelfuse 314 series includes CE, K-MARK, and PSE certifications in addition to CSA and UL.

Q: Are 0314007.HXP, 0314007.MXP, and 0314007.VXP interchangeable?

A: Yes. These three Littelfuse 314 series variants are functionally equivalent for the specified electrical parameters (7 A, 250 V AC, 125 V DC, Fast Blow, 3AB/3AG package). All three share identical current rating, voltage rating, response time, mechanical dimensions, breaking capacity, melting I²t, DC cold resistance, operating temperature range, and approval certifications. Internal construction differences do not affect substitution compatibility.

Q: What holder types are compatible with these fuses?

A: All listed parts require a holder and are compatible with 3AB and 3AG holder types. The mechanical dimensions (0.250" diameter × 1.250" length, or 6.35 mm × 31.75 mm) are standardized across all substitute parts, ensuring mechanical fit in any 3AB or 3AG holder.

Q: Does the BK/GBB-7-R have lower breaking capacity than the ABC-7-R?

A: The BK/GBB-7-R specifies 10 kA breaking capacity, while the ABC-7-R specifies 200 A AC and 10 kA DC. The GBB series part meets the DC breaking capacity specification but differs in AC breaking capacity specification. Selection should be based on application requirements for AC breaking capacity.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts (BK/ABC-7-R, BK/GBB-7-R, 0314007.HXP, 0314007.MXP, 0314007.VXP) are ROHS3 compliant, matching the environmental compliance status of the original ABC-7-R.

Q: What approval certifications should I consider for international applications?

A: The ABC-7-R and BK/ABC-7-R carry CSA and UL certifications. The BK/GBB-7-R adds UR certification. The Littelfuse 314 series (0314007.HXP, 0314007.MXP, 0314007.VXP) provides the broadest certification coverage, including CE, CSA, K-MARK, PSE, and UL (with VXP including KC instead of K-MARK). Selection should align with regional regulatory requirements.
