Key Parameters

Substitute Part Grouping Explanation

Substitution of the CH141DMS is determined by electrical and mechanical compatibility across the following parameters:

• Current Rating: 40 A (exact match required)
• Voltage Rating: 600V (exact match required)
• Fuse Size: 14mm x 51mm cartridge (exact match required)
• Mounting Type: DIN Rail (exact match required)
• Number of Circuits: 1 (exact match required)
• Termination Style: Screw Terminal (exact match required)

The CH141BMS meets all substitution criteria, maintaining identical electrical specifications and mechanical form factor while offering active product status and current compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The CH141BMS is the direct equivalent for CH141DMS replacement. Both components share identical electrical ratings (40 A, 600V) and mechanical specifications (14mm x 51mm cartridge, DIN Rail mounting, single circuit, screw terminal). The CH141BMS offers the advantage of active product status and RoHS compliance, making it suitable for new installations and systems requiring current regulatory alignment.

Frequently Asked Questions (FAQ)

Q: Can CH141BMS be used as a direct replacement for CH141DMS? A: Yes. Both components have identical current rating (40 A), voltage rating (600V), fuse size (14mm x 51mm), mounting type (DIN Rail), circuit count (1), and termination style (screw terminal). Mechanical and electrical compatibility is complete.

Q: What is the significance of the product status difference? A: CH141DMS is classified as obsolete, indicating it is no longer manufactured. CH141BMS is active, ensuring ongoing availability and manufacturer support. For new designs or system upgrades, CH141BMS is the appropriate selection.

Q: Are there any compliance differences between these parts? A: CH141BMS is RoHS Compliant, meeting current environmental regulations. CH141DMS compliance status is not specified in available documentation. For applications requiring RoHS certification, CH141BMS is the required choice.

Q: Will CH141BMS fit existing CH141DMS mounting locations? A: Yes. Both components use identical DIN Rail mounting and have the same physical dimensions. No mechanical modifications to existing installations are required.

Q: What fuse types are compatible with these holders? A: Both holders accept 14mm x 51mm cartridge fuses rated for 40 A at 600V. Fuse selection must match the holder's electrical specifications.
