SL405M Equivalent & Substitute Parts

Part Overview

The SL405M is a 5-position circular connector plug with male pins and solder cup termination, manufactured by Switchcraft Inc. as part of the Slim-Line® SL40 series. This connector is designed for audio, industrial, marine, and medical applications requiring shielded connections with a 5-ampere current rating.

The SL405M is classified as obsolete. Locating equivalent or substitute components is necessary to support ongoing maintenance, repair, and system integration where this connector type is specified or currently deployed.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SL405M is determined by strict equivalence across the following critical parameters:

• Connector type and pin configuration (Plug, Male Pins, 5-position)
• Shell size and insert designation (SL-5M)
• Termination method (Solder Cup)
• Fastening mechanism (Threaded coupling nut)
• Electrical performance (5A current rating, shielded design)
• Physical dimensions (0.280" cable opening)
• Material and finish specifications (Copper Alloy shell, Nickel finish, Silver contact finish)

The SL405MX meets all these criteria and is therefore a direct substitute for the SL405M. Both parts share identical electrical, mechanical, and material specifications within the Slim-Line® SL40 series.

Parameter Comparison

Engineering Selection Recommendations

The SL405MX is the direct substitute for the SL405M. Both connectors are electrically and mechanically identical across all specified parameters.

The primary distinction between the two parts is product status and regulatory compliance. The SL405M is obsolete and RoHS non-compliant, while the SL405MX is active and ROHS3 compliant. For new designs, system upgrades, or applications subject to RoHS requirements, the SL405MX is the appropriate selection. For legacy system maintenance where the original SL405M specification must be maintained, the SL405M remains available in inventory.

Both parts are REACH unaffected and classified under ECCN EAR99, with identical tariff classification (HTSUS 8536.69.4020).

Frequently Asked Questions (FAQ)

Q: Can the SL405MX be used as a direct replacement for the SL405M?

A: Yes. The SL405MX is a direct substitute. All electrical, mechanical, and material specifications are identical. The connectors are pin-compatible and mechanically interchangeable.

Q: What is the difference between SL405M and SL405MX?

A: The SL405MX is the active production variant of the SL405M. The SL405M is obsolete. The SL405MX is ROHS3 compliant, while the SL405M is RoHS non-compliant. Functionally and mechanically, they are equivalent.

Q: Are there packaging differences between SL405M and SL405MX?

A: The SL405MX is supplied in bulk packaging. The SL405M packaging designation is not specified. Both parts are identical connectors; packaging differences do not affect connector performance or compatibility.

Q: What applications are these connectors suitable for?

A: Both the SL405M and SL405MX are specified for audio, industrial, marine, and medical applications. The 5-ampere current rating, shielded design, and UL94 V-0 flammability rating support these application categories.

Q: What is the cable opening specification?

A: The cable opening for both connectors is 0.280 inches (7.10 millimeters). This dimension determines the maximum cable diameter that can be accommodated by the connector strain relief and cable clamp.

Q: Are these connectors RoHS compliant?

A: The SL405M is RoHS non-compliant. The SL405MX is ROHS3 compliant. For applications requiring RoHS compliance, the SL405MX must be specified.
