Equivalent & Substitute Parts for MDL-1/16-R

Part Overview

The MDL-1/16-R is a 63 mA, 250 V AC/DC slow-blow glass fuse cartridge manufactured by Eaton Electronics Division. This component is designed for circuit protection in applications requiring precise current limitation at low amperage levels. The fuse operates with a 3AB, 3AG form factor (1/4" x 1-1/4") and requires a compatible holder for installation. The part maintains Active product status with full compliance to CE, CSA, and UL approval agencies. Equivalent and substitute parts are identified to support procurement flexibility, inventory management, and supply chain continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MDL-1/16-R are classified based on strict electrical and mechanical parameter alignment:

Direct Equivalent (Identical Electrical and Mechanical Parameters): The BK/MDL-1/16-R maintains identical specifications across all critical parameters: 63 mA current rating, 250 V AC voltage rating, slow-blow response time, 3AB/3AG package form factor, 35 A breaking capacity, and identical physical dimensions. This part is manufactured by the same supplier (Eaton Electronics Division) and carries equivalent approval certifications. The primary distinction is enhanced RoHS3 compliance status and improved moisture sensitivity rating (MSL 1 Unlimited).

Similar Equivalent (Functionally Compatible with Minor Parameter Variance): The 0313.062MXP (Littelfuse Inc., Series 313) operates within the same electrical and mechanical envelope with a 62 mA current rating versus the 63 mA specification of the main part. Both parts share identical voltage rating (250 V AC), response time classification (slow-blow), package form factor (3AB, 3AG, 1/4" x 1-1/4"), breaking capacity (35 A), and physical dimensions. The 1 mA current rating difference falls within standard fuse tolerance bands for this product category. Both parts carry CE, CSA, and UL approvals and maintain RoHS3 compliance.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Identical Specifications): The BK/MDL-1/16-R is the direct equivalent to MDL-1/16-R. Both parts carry Active product status and maintain full compliance with CE, CSA, and UL approval requirements. Selection between these two parts is determined by supply availability and inventory status rather than technical performance criteria. The BK/MDL-1/16-R offers enhanced RoHS3 compliance and improved moisture sensitivity rating (MSL 1 Unlimited), making it suitable for applications with extended storage or high-humidity environments.

For Functionally Compatible Substitution: The 0313.062MXP (Littelfuse Inc.) operates as a functionally compatible substitute with a 62 mA current rating. This 1 mA variance from the 63 mA specification falls within standard fuse tolerance classifications for this product category and does not alter the protective function in circuits designed for the MDL-1/16-R. The part maintains identical voltage rating, response time, package form factor, breaking capacity, and physical dimensions. All three parts carry equivalent CE, CSA, and UL certifications and RoHS3 compliance status. Selection of the 0313.062MXP is appropriate when MDL-1/16-R or BK/MDL-1/16-R inventory is unavailable and the application tolerates the specified current rating variance.

Frequently Asked Questions (FAQ)

Q: Can the BK/MDL-1/16-R be used as a direct replacement for MDL-1/16-R? A: Yes. The BK/MDL-1/16-R is a direct equivalent with identical electrical and mechanical specifications. Both parts are manufactured by Eaton Electronics Division, carry the same current rating (63 mA), voltage rating (250 V AC), response time (slow-blow), package form factor (3AB, 3AG), and approval certifications (CE, CSA, UL). The BK variant offers enhanced RoHS3 compliance and improved moisture sensitivity rating.

Q: Is the 0313.062MXP compatible with circuits designed for the MDL-1/16-R? A: The 0313.062MXP is functionally compatible for applications tolerating a 62 mA current rating. The 1 mA difference from the 63 mA specification is within standard fuse tolerance bands. All other critical parameters—voltage rating (250 V AC), response time (slow-blow), package form factor (3AB, 3AG, 1/4" x 1-1/4"), breaking capacity (35 A), and approval certifications (CE, CSA, UL)—are identical. Compatibility depends on circuit design margins and application requirements.

Q: What are the key parameters that determine substitution eligibility? A: Substitution eligibility is determined by: current rating (63 mA or within tolerance), voltage rating (250 V AC minimum), fuse type (cartridge, glass), response time (slow-blow), package form factor (3AB, 3AG, 1/4" x 1-1/4"), breaking capacity (35 A), physical dimensions (0.250" Dia x 1.250" L), and approval agency certifications (CE, CSA, UL). All substitute parts must meet these criteria.

Q: Do all substitute parts require the same holder? A: Yes. All three parts—MDL-1/16-R, BK/MDL-1/16-R, and 0313.062MXP—use the identical 3AB, 3AG form factor with dimensions 1/4" x 1-1/4" (6.35mm x 31.75mm). They are mechanically interchangeable and require the same compatible holder.

Q: What is the difference between RoHS and RoHS3 compliance? A: Both designations indicate compliance with Restriction of Hazardous Substances regulations. RoHS3 represents the current regulatory standard with updated substance restrictions. The BK/MDL-1/16-R and 0313.062MXP carry RoHS3 certification, while the MDL-1/16-R carries RoHS compliance. All three parts meet hazardous substance restrictions for their respective regulatory frameworks.

Q: Are all substitute parts in active production? A: Yes. The MDL-1/16-R, BK/MDL-1/16-R, and 0313.062MXP all maintain Active product status with current inventory availability (1110 Pcs, 1881 Pcs, and 1837 Pcs respectively).
