MHS133G Equivalent & Substitute Parts

Part Overview

The MHS133G is a slide switch manufactured by TE Connectivity ALCOSWITCH Switches, configured as a single-pole triple-throw (SP3T) switch with a rated capacity of 0.4VA at 20V. This through-hole mounted component features gold-plated copper alloy contacts, polyoxymethylene actuator material, and epoxy sealed terminals. The MHS133G is classified as obsolete, making identification of equivalent active alternatives necessary for ongoing design support and procurement continuity.

Substitute Part Grouping Explanation

Substitution of the MHS133G is based on electrical and mechanical parameter equivalence within the MHS series. The substitute part 1825255-8 maintains identical electrical specifications including SP3T circuit configuration, 0.4VA current rating, and 20V voltage rating (both AC and DC). Mechanical parameters including actuator length (4.50mm), switch travel (2.00mm), operating force (600gf), and contact material composition (gold-plated copper alloy) are preserved. Both components feature through-hole mounting with PC pin termination, epoxy sealed terminals, and identical operating temperature range (-20°C to 85°C). The substitution is valid based on these matching parameters: circuit topology, electrical ratings, contact characteristics, mechanical dimensions, and environmental specifications.

Parameter Comparison

Engineering Selection Recommendations

The 1825255-8 serves as the direct equivalent substitute for the obsolete MHS133G. Both components are manufactured by TE Connectivity ALCOSWITCH Switches and share identical electrical and mechanical specifications across all critical parameters. The primary distinction is product status: the MHS133G is obsolete while 1825255-8 is active, ensuring ongoing availability and manufacturing support. The 1825255-8 carries ROHS3 compliance certification, meeting current regulatory requirements for electronic components. For applications requiring the MHS133G, the 1825255-8 provides full functional and dimensional compatibility with the added benefit of active product status and regulatory compliance. Packaging differences (bulk for 1825255-8 versus unspecified for MHS133G) do not affect electrical or mechanical performance in circuit applications.

Frequently Asked Questions (FAQ)

Q: Can the 1825255-8 directly replace the MHS133G in existing designs?

A: Yes. The 1825255-8 is electrically and mechanically equivalent to the MHS133G. All electrical ratings (0.4VA, 20V AC/DC), circuit configuration (SP3T), contact characteristics (gold-plated copper alloy), and mechanical dimensions (4.50mm actuator length, 2.00mm travel, 600gf operating force) are identical. Through-hole mounting and PC pin termination are preserved, enabling direct substitution in PCB layouts.

Q: What is the primary reason for substituting the MHS133G?

A: The MHS133G is classified as obsolete. The 1825255-8 is the active equivalent from the same manufacturer and series, ensuring continued component availability and manufacturing support for new production and field replacements.

Q: Are there compliance differences between these parts?

A: The 1825255-8 is certified ROHS3 compliant, meeting current regulatory standards for restricted substances. The MHS133G compliance status is not specified in available documentation. For applications subject to ROHS3 requirements, the 1825255-8 is the appropriate selection.

Q: Do packaging differences affect circuit performance?

A: No. The 1825255-8 is supplied in bulk packaging while the MHS133G packaging is unspecified. Packaging format does not alter electrical performance, mechanical function, or circuit compatibility. Packaging selection is determined by procurement and inventory requirements rather than technical performance.

Q: Are the contact materials and finishes identical?

A: Yes. Both the MHS133G and 1825255-8 feature copper alloy contacts with gold plating and epoxy sealed terminals. Contact material composition and finish specifications are identical, ensuring equivalent electrical performance and environmental protection.

Q: What is the operating temperature range for both components?

A: Both components operate across the identical temperature range of -20°C to 85°C, ensuring equivalent thermal performance in specified environmental conditions.

Q: Are mechanical life and electrical life ratings the same?

A: Yes. Both components are rated for 15,000 mechanical cycles and 15,000 electrical cycles, providing identical reliability specifications for switch operation and contact durability.
