MSS4335 Equivalent & Substitute Parts

Part Overview

The MSS4335 is a slide switch manufactured by TE Connectivity ALCOSWITCH Switches, configured as a 4-pole 3-throw (4P3T) switch with a 300mA AC current rating at 125V. This through-hole mounted component features a standard actuator with 9.00mm length and silver-plated copper alloy contacts. The MSS4335 is classified as an obsolete product. Locating equivalent and substitute parts is necessary due to the discontinued status of this component, which may impact procurement availability for new designs or replacement applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MSS4335 is determined by strict equivalence across all electrical and mechanical parameters. The substitute part must maintain identical specifications in the following critical areas:

Electrical Parameters: Circuit configuration (4P3T), current rating (300mA AC), voltage rating (125V AC), and contact timing (Shorting MBB) must be identical.

Mechanical Parameters: Mounting type (through hole), termination style (PC pin), actuator length (9.00mm), switch travel (2.00mm), and operating force (600gf) must match exactly.

Material and Environmental Specifications: Contact material (copper alloy with silver finish), actuator material (polyoxymethylene/acetal), operating temperature range (-20°C to 85°C), mechanical life (15,000 cycles), and electrical life (15,000 cycles) must be equivalent.

Functional Characteristics: Switch function (On-On-On) and contact finish (silver) must be identical.

Parts meeting all these criteria are classified as direct equivalents and may be substituted without circuit redesign or board layout modification.

Parameter Comparison

Engineering Selection Recommendations

The part 1825269-1 is a direct equivalent to the MSS4335 based on complete parameter alignment across all electrical, mechanical, and material specifications. Both components are manufactured by TE Connectivity ALCOSWITCH Switches and share identical circuit configuration, current and voltage ratings, contact characteristics, and physical dimensions.

Both parts carry obsolete product status, indicating that neither component is in active production. Selection between these parts should be based on procurement availability and inventory status. The MSS4335 has 661 pieces in stock, while the 1825269-1 has 875 pieces available. Both components carry identical export classification (EAR99) and tariff codes (8536.50.9050).

No circuit redesign, board layout modification, or functional testing is required when substituting between these parts. The components are mechanically and electrically interchangeable for all applications within the specified operating parameters.

Frequently Asked Questions (FAQ)

Q: Can the 1825269-1 be used as a direct replacement for the MSS4335?

A: Yes. The 1825269-1 is a direct equivalent to the MSS4335. All electrical parameters (4P3T configuration, 300mA AC, 125V AC), mechanical parameters (through-hole mounting, 9.00mm actuator length, 2.00mm travel), and material specifications (copper alloy contacts with silver finish, POM actuator) are identical. No circuit modifications are required.

Q: Are there any differences in the contact material or finish between these parts?

A: No. Both the MSS4335 and 1825269-1 use copper alloy contacts with silver finish. Contact timing is shorting (MBB) for both parts, and both feature epoxy sealed terminals.

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

A: Both the MSS4335 and 1825269-1 operate across the temperature range of -20°C to 85°C.

Q: Do both parts have the same mechanical and electrical life ratings?

A: Yes. Both components are rated for 15,000 mechanical cycles and 15,000 electrical cycles with an operating force of 600gf.

Q: Are there any compliance or certification differences between these parts?

A: Both parts carry identical export classification (EAR99) and tariff codes (8536.50.9050). Both are classified as obsolete products. REACH status differs slightly: MSS4335 is listed as REACH Unaffected, while 1825269-1 is listed as Vendor Undefined. This does not affect substitution eligibility.

Q: What is the through-hole termination style for these switches?

A: Both parts use PC pin termination for through-hole mounting on printed circuit boards.

Q: Can these parts be used in applications requiring 300mA at 125V AC?

A: Yes. Both the MSS4335 and 1825269-1 are rated for 300mA AC at 125V AC and are suitable for applications within these electrical parameters.
