MSS2225G Equivalent & Substitute Parts

Part Overview

The MSS2225G is a slide switch manufactured by TE Connectivity ALCOSWITCH Switches, configured as a Double Pole Double Throw (DPDT) switch with a rated capacity of 0.4VA at 20V. This component features through-hole mounting with gold-plated copper alloy contacts and is designed for applications requiring reliable switching with momentary or maintained contact operation.

The MSS2225G is classified as obsolete. Locating equivalent substitute parts is necessary to support ongoing maintenance, repair, and production requirements for systems utilizing this component. Active alternatives with compatible electrical and mechanical specifications are available to ensure design continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MSS2225G is determined by strict equivalence across the following critical parameters:

Electrical Compatibility Requirements:

• Circuit configuration must be DPDT
• Contact timing must be Shorting (MBB)
• Switch function must be On-On
• Current rating must be 0.4VA (AC/DC)
• Voltage ratings must be 20V (both AC and DC)

Mechanical Compatibility Requirements:

• Mounting type must be Through Hole
• Termination style must be PC Pin
• Contact material must be Copper Alloy with Gold finish
• Operating temperature range must be -20°C to 85°C
• Mechanical and electrical life must be 15,000 cycles
• Operating force must be 600gf
• Switch travel must be 2.00mm

Acceptable Variations:

• Actuator length may vary (5.41mm to 6.20mm) without affecting electrical or mechanical function
• Product status may differ (obsolete to active)
• Packaging configuration may differ (bulk vs. standard)
• RoHS compliance status may differ
• Moisture Sensitivity Level (MSL) may differ

The substitute part 1825262-2 meets all critical electrical and mechanical parameters while offering improved product status and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The MSS2225G is an obsolete component. The substitute part 1825262-2 provides direct functional equivalence with all critical electrical and mechanical parameters matched identically.

Selection Basis:

The 1825262-2 is the appropriate substitute for the MSS2225G based on the following factors:

1. Electrical Equivalence: All voltage ratings, current capacity, circuit configuration, and contact timing specifications are identical between the two parts.

2. Mechanical Equivalence: Mounting type, termination style, contact material, operating temperature range, mechanical life, electrical life, operating force, and switch travel are identical.

3. Product Status: The 1825262-2 is classified as active, ensuring ongoing availability and manufacturer support, whereas the MSS2225G is obsolete.

4. Compliance Improvement: The 1825262-2 is ROHS3 compliant, addressing regulatory requirements that may apply to new designs or production runs. The MSS2225G is RoHS non-compliant.

5. Actuator Length Variation: The 1825262-2 features a 6.20mm actuator length compared to the MSS2225G at 5.41mm. This 0.79mm difference does not affect electrical or mechanical function and is acceptable for through-hole mounted slide switches in standard applications.

6. Packaging: The 1825262-2 is available in bulk packaging with higher inventory levels (2830 pcs), supporting production requirements.

Frequently Asked Questions (FAQ)

Q: Can the 1825262-2 be used as a direct replacement for the MSS2225G in existing designs?

A: Yes. The 1825262-2 meets all critical electrical and mechanical specifications of the MSS2225G. The actuator length difference (6.20mm vs. 5.41mm) does not affect electrical performance or standard through-hole mounting applications. Physical clearance in the enclosure or PCB layout should be verified for the increased actuator length.

Q: What is the significance of the actuator length difference between these parts?

A: The actuator length determines the physical extension of the switch lever from the mounting surface. The 1825262-2 extends 0.79mm further than the MSS2225G. This variation is acceptable for most applications but should be confirmed against mechanical drawings and enclosure constraints to ensure adequate clearance and proper operation.

Q: Are there any electrical performance differences between the MSS2225G and 1825262-2?

A: No. Both parts are rated for 0.4VA at 20V (AC/DC), feature identical DPDT configuration with Make Before Break contact timing, and support the same operating temperature range (-20°C to 85°C). Mechanical life, electrical life, and operating force specifications are identical.

Q: Why is the 1825262-2 classified as active while the MSS2225G is obsolete?

A: Product status reflects manufacturer support and availability. The MSS2225G has been discontinued by TE Connectivity. The 1825262-2 is the current production equivalent and is actively manufactured and supported.

Q: Does the RoHS3 compliance of the 1825262-2 affect compatibility with the MSS2225G application?

A: RoHS3 compliance indicates the 1825262-2 meets current environmental and regulatory standards for restricted substances. This is an improvement over the MSS2225G and does not create incompatibility. Applications subject to RoHS requirements should use the 1825262-2.

Q: What is the MSL rating difference, and does it matter?

A: The MSS2225G has MSL Not Applicable, while the 1825262-2 is rated MSL 1 (Unlimited). MSL 1 indicates the component has unlimited shelf life without moisture sensitivity concerns. This is an improvement and does not affect compatibility.

Q: Are both parts available from the same manufacturer?

A: Yes. Both the MSS2225G and 1825262-2 are manufactured by TE Connectivity ALCOSWITCH Switches. The 1825262-2 represents the current production line for this switch type.

Q: Can the 1825262-2 be used in high-volume production to replace existing MSS2225G inventory?

A: Yes. The 1825262-2 is available in bulk packaging with substantial inventory (2830 pcs). All electrical and mechanical specifications support direct substitution in production environments. Actuator length clearance should be confirmed during design validation.
