MHS133 Equivalent & Substitute Parts

Part Overview

The MHS133 is a slide switch manufactured by TE Connectivity ALCOSWITCH Switches, configured as a single-pole triple-throw (SP3T) switch with a 300mA AC current rating at 125V. This through-hole mounted component features shorting contact timing (make-before-break) and is designed for on-on-on switching applications. The MHS133 is classified as obsolete, necessitating identification of active equivalent parts to maintain design continuity and ensure component availability for new production and repair applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete MHS133 is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part must maintain identical specifications in the following categories:

Electrical Parameters: Circuit configuration (SP3T), contact timing (shorting/MBB), current rating (300mA AC), and voltage rating (125V AC) must be identical to ensure functional compatibility within existing circuit designs.

Mechanical Parameters: Mounting type (through hole), termination style (PC pin), actuator length (4.50mm), switch travel (2.00mm), and operating force (600gf) must match to ensure physical compatibility with printed circuit board layouts and mechanical assemblies.

Material and Environmental Parameters: Contact material (copper alloy), contact finish (silver), actuator material (POM), and operating temperature range (-20°C to 85°C) must be equivalent to maintain electrical performance and environmental durability.

Performance Parameters: Mechanical life (15,000 cycles) and electrical life (15,000 cycles) must be maintained to ensure equivalent service life expectations.

The substitute part 1825255-7 meets all these criteria and is classified as active, providing continued component availability.

Parameter Comparison

Engineering Selection Recommendations

The part 1825255-7 is the direct equivalent substitute for the obsolete MHS133. All electrical, mechanical, and environmental parameters are identical, ensuring drop-in compatibility for circuit designs and PCB layouts.

Product Status Advantage: The MHS133 is classified as obsolete, while 1825255-7 is active. Selection of the active part ensures long-term component availability and supply chain continuity for production and field repair applications.

Compliance Enhancement: The 1825255-7 carries ROHS3 compliance certification, providing improved environmental and regulatory alignment compared to the MHS133, which does not specify RoHS status. Both parts maintain identical ECCN (EAR99) and HTSUS (8536.50.9050) classifications.

Packaging Consideration: The 1825255-7 is supplied in bulk packaging, whereas the MHS133 packaging specification is not provided. Bulk packaging is standard for production environments and offers cost efficiency for volume applications.

For new designs, repair operations, and production continuity, 1825255-7 is the specified equivalent replacement for MHS133.

Frequently Asked Questions (FAQ)

Q: Can 1825255-7 be used as a direct replacement for MHS133 in existing circuit designs?

A: Yes.
