SL175M Equivalent & Substitute Parts

Part Overview

The SL175M is a 5-position circular connector receptacle with male pins manufactured by Switchcraft Inc. as part of the Slim-Line® SL17 series. This component is designed for panel mount applications with bulkhead front-side nut fastening and solder cup termination. The part is currently obsolete, making identification of suitable alternatives essential for ongoing system maintenance and new design implementations where this connector type is specified.

Key Parameters

Substitute Part Grouping Explanation

The SL175MX qualifies as a direct substitute for the SL175M based on identical electrical and mechanical parameters. Substitution is valid when the following criteria are met:

• Connector type, position count, and shell size match exactly (Receptacle, Male Pins; 5 positions; SL-5M)
• Mounting configuration is identical (Panel Mount, Bulkhead - Front Side Nut)
• Termination method is the same (Solder Cup)
• Material specifications are equivalent (Zinc Alloy shell, Nickel finish, Silver contact finish, Copper Alloy contacts)
• Current rating and flammability rating are maintained (5A, UL94 V-0)
• Shielding configuration is identical (Unshielded)

The primary distinction between these parts is product status and regulatory compliance, not functional or mechanical characteristics.

Parameter Comparison

Engineering Selection Recommendations

The SL175MX is the appropriate substitute for the obsolete SL175M. Both parts are functionally and mechanically identical across all specified electrical and mechanical parameters. The SL175MX offers the additional advantage of active product status, ensuring continued availability and manufacturer support.

For applications requiring RoHS3 compliance, the SL175MX is the mandated choice, as the SL175M does not meet this regulatory requirement. Both parts maintain REACH Unaffected status and EAR99 export classification.

The SL175MX is available in bulk packaging with unlimited moisture sensitivity level rating, suitable for standard storage and handling conditions in industrial, audio, marine, and medical applications.

Frequently Asked Questions (FAQ)

Q: Can SL175MX be used as a direct replacement for SL175M in existing designs?

A: Yes. The SL175MX is mechanically and electrically identical to the SL175M across all specified parameters including connector type, position count, shell size, mounting configuration, termination method, and current rating.

Q: What is the primary reason to transition from SL175M to SL175MX?

A: The SL175M is obsolete. The SL175MX is an active product from the same manufacturer and series, ensuring ongoing availability and support. Additionally, the SL175MX meets ROHS3 compliance requirements, whereas the SL175M does not.

Q: Are there any mechanical or dimensional differences between these parts?

A: No. Both parts share identical shell size (SL-5M), mounting type (Panel Mount, Bulkhead - Front Side Nut), and all material specifications (Zinc Alloy shell, Nickel finish, Silver contact finish).

Q: What is the difference in packaging between SL175M and SL175MX?

A: The SL175M packaging specification is not provided. The SL175MX is supplied in bulk packaging, which is standard for active production inventory.

Q: Are both parts suitable for the same applications?

A: Yes. Both parts are specified for Audio, Industrial, Marine, and Medical applications with identical current rating (5A) and flammability rating (UL94 V-0).
