Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MDA-V-30-R are classified based on strict electrical and mechanical parameter alignment. The substitution logic is determined by the following critical parameters:

Electrical Parameters:

• Current Rating: 30 A (exact match required)
• Voltage Rating AC: 250 V (exact match required)
• Voltage Rating DC: 125 V (exact match required)
• Response Time: Slow Blow (exact match required)

Mechanical Parameters:

• Fuse Type: Cartridge, Ceramic (exact match required)
• Package / Case: 3AB, 3AG, 1/4" x 1-1/4" (Axial) (exact match required)
• Mounting Type: Through Hole (exact match required)

Compliance Parameters:

• RoHS Status: ROHS3 Compliant (minimum requirement)
• Approval Agencies: CE, CSA, UL (minimum requirement)

Two substitute parts meet these criteria:

1. BK/MDA-V-30-R (Eaton - Electronics Division) - Parametric equivalent with identical electrical and mechanical specifications
2. 0325030.MXP (Littelfuse Inc.) - Direct manufacturer alternative with equivalent electrical and mechanical specifications

Parameter Comparison

Engineering Selection Recommendations

BK/MDA-V-30-R Selection Criteria:

The BK/MDA-V-30-R is a parametric equivalent manufactured by Eaton - Electronics Division. This substitute maintains identical electrical specifications (30 A, 250 V AC, 125 V DC), mechanical dimensions (0.266" Dia x 1.292" L), and performance characteristics (Slow Blow, 1096.7 Melting I²t). Both parts share the same approval agencies (CE, CSA, UL) and RoHS3 compliance status. This substitute is suitable for direct replacement in applications where Eaton sourcing is preferred or required. Inventory availability is 1655 pieces.

0325030.MXP Selection Criteria:

The 0325030.MXP is a direct manufacturer alternative produced by Littelfuse Inc. This substitute meets all critical electrical parameters (30 A, 250 V AC, 125 V DC, Slow Blow response). The part maintains mechanical compatibility within the 3AB, 3AG package standard, with dimensional variance of 0.009" in diameter and 0.004" in length. The 0325030.MXP provides additional approval certifications (K-MARK, PSE) beyond the minimum requirement and demonstrates superior inventory availability (16311 pieces). The higher breaking capacity (400A AC, 600A DC) and increased melting I²t (1690) indicate enhanced performance margins. This substitute is suitable for applications requiring cross-manufacturer sourcing flexibility or extended supply chain resilience.

Frequently Asked Questions (FAQ)

Q: Can BK/MDA-V-30-R be used as a direct replacement for MDA-V-30-R?

A: Yes. The BK/MDA-V-30-R is a parametric equivalent with identical electrical ratings (30 A, 250 V AC, 125 V DC), fuse type (Ceramic Cartridge), response time (Slow Blow), package designation (3AB, 3AG), and physical dimensions (0.266" Dia x 1.292" L). Both parts are manufactured by Eaton - Electronics Division and carry the same approval certifications (CE, CSA, UL). Direct substitution is supported.

Q: What are the dimensional differences between MDA-V-30-R and 0325030.MXP?

A: The 0325030.MXP has a diameter of 0.275" compared to 0.266" for the MDA-V-30-R, representing a 0.009" increase. The length is 1.288" for the 0325030.MXP versus 1.292" for the MDA-V-30-R, representing a 0.004" decrease. Both parts conform to the 3AB, 3AG package standard and are mechanically compatible with through-hole mounting applications.

Q: Are there electrical performance differences between the substitute parts?

A: The primary electrical parameters (current rating, voltage ratings, and response time) are identical across all three parts. However, the 0325030.MXP exhibits different secondary characteristics: breaking capacity of 400A AC and 600A DC (compared to 1.5kA AC and 10kA DC for the Eaton parts), and a melting I²t of 1690 (compared to 1096.7 for the Eaton parts). These differences indicate enhanced performance margins in the Littelfuse product but do not affect compatibility in applications designed for the MDA-V-30-R specifications.

Q: What is the DC cold resistance difference between parts?

A: The MDA-V-30-R and BK/MDA-V-30-R both have a DC cold resistance of 0.00243 Ohms. The 0325030.MXP has a lower DC cold resistance of 0.0019 Ohms, representing approximately 22% reduction. This lower resistance may result in marginally reduced voltage drop across the fuse element during normal operation.

Q: Which substitute part offers the best inventory availability?

A: The 0325030.MXP (Littelfuse Inc.) provides the highest inventory availability with 16311 pieces in stock, compared to 1655 pieces for BK/MDA-V-30-R and 1023 pieces for the main part MDA-V-30-R. This availability advantage may be significant for high-volume production requirements or extended supply chain planning.

Q: Are all three parts RoHS3 compliant?

A: Yes. The MDA-V-30-R, BK/MDA-V-30-R, and 0325030.MXP are all ROHS3 compliant. All three parts are also REACH unaffected and carry the same ECCN (EAR99) and HTSUS (8536.10.0040) classifications.

Q: What additional certifications does the 0325030.MXP carry?

A: The 0325030.MXP carries CE, CSA, K-MARK, PSE, and UL certifications. The MDA-V-30-R and BK/MDA-V-30-R carry CE, CSA, and UL certifications. The additional K-MARK and PSE certifications on the 0325030.MXP provide expanded geographic compliance coverage.
