Key Parameters

Substitute Part Grouping Explanation

Substitution of the 141SM102 is determined by strict alignment of electrical and mechanical parameters. The primary substitution criteria are:

Electrical Compatibility Parameters:

• Circuit configuration (SPDT)
• Switch function (On-Mom)
• Current and voltage ratings (AC/DC)
• Operating temperature range

Mechanical Compatibility Parameters:

• Actuator type (Round Pin Plunger)
• Mounting type (Chassis Mount)
• Termination style (Solder Lug)
• Operating position and force characteristics

Compliance Parameters:

• RoHS status
• Moisture sensitivity level

The substitute parts are grouped into two categories based on electrical rating alignment:

Category 1 - Direct Electrical Equivalents (11A/250V AC):

• 41SM1 (Honeywell SM Series) - Active status, identical electrical ratings
• MBZ101A01C01X01 and MBZ101A01C02X01 (APEM MBZ Series) - 10A AC rating with 250V AC, active status

Category 2 - Reduced Rating Substitutes (5A/125V AC):

• MS0850500F060S1A, MS0850500F080S1A, MS0850500F250S1A, MS0850500F295S1A (E-Switch MS Series) - 5A AC at 125V, active status

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute - 41SM1 (Honeywell SM Series)

The 41SM1 is the optimal substitute for the 141SM102. Both components share identical electrical ratings (11A at 250V AC, 5A at 30V DC), mechanical characteristics (141gf operating force, 28gf release force), and operating temperature range (-55°C to 125°C). The 41SM1 maintains active product status and RoHS compliance. This part provides direct functional equivalence with no electrical or mechanical derating.

Secondary Substitutes - MBZ101A01C01X01 and MBZ101A01C02X01 (APEM MBZ Series)

These APEM components provide SPDT On-Mom functionality with 10A AC at 250V, representing a 1A reduction from the 141SM102 specification. Both parts feature identical 0.330" operating position and maintain chassis mount solder lug configuration. Operating temperature range is reduced to -40°C to 85°C. These parts are suitable for applications where the 11A rating is not fully utilized and the narrower temperature range is acceptable. Both are active products with ROHS3 compliance.

Tertiary Substitutes - E-Switch MS0850500 Series (MS0850500F060S1A, MS0850500F080S1A, MS0850500F250S1A, MS0850500F295S1A)

The E-Switch MS series components provide SPDT On-Mom functionality with reduced electrical ratings (5A at 125V AC). These parts are suitable only for applications where the 141SM102 is operated at reduced current and voltage levels. Operating force variants range from 60gf to 295gf, allowing selection based on actuation requirements. Operating temperature range is limited to -25°C to 85°C. All E-Switch variants are active products with ROHS3 compliance and higher mechanical life ratings (1,000,000 cycles).

Frequently Asked Questions (FAQ)

Q: Can the 41SM1 directly replace the 141SM102 in all applications?

A: Yes. The 41SM1 provides identical electrical ratings, mechanical characteristics, and operating temperature range. Both components are SPDT On-Mom switches with 11A at 250V AC and 5A at 30V DC ratings. The primary difference is product status: 141SM102 is obsolete while 41SM1 is active.

Q: What is the difference between the Honeywell 41SM1 and APEM MBZ101 series substitutes?

A: The 41SM1 maintains the full 11A AC rating at 250V, while the APEM MBZ101 series is rated for 10A AC at 250V. The APEM parts also have a reduced operating temperature range (-40°C to 85°C versus -55°C to 125°C) and significantly higher mechanical life (10,000,000 cycles versus 80,000 cycles). The APEM parts are suitable when the 1A current reduction and narrower temperature range are acceptable.

Q: When should the E-Switch MS0850500 series be used as a substitute?

A: The E-Switch MS series should be used only when the application operates at reduced electrical levels (5A at 125V AC maximum). These parts are not suitable for applications requiring the full 11A at 250V AC rating of the 141SM102. The E-Switch variants offer higher mechanical life (1,000,000 cycles) and multiple operating force options (60gf to 295gf).

Q: Are all substitute parts RoHS compliant?

A: Yes. The 141SM102 is RoHS Compliant, and all substitute parts (41SM1, MBZ101A01C01X01, MBZ101A01C02X01, and all E-Switch MS0850500 variants) are either RoHS Compliant or ROHS3 Compliant.

Q: What is the difference in operating force between the 141SM102 and substitute parts?

A: The 141SM102 and 41SM1 both require 141gf operating force with 28gf release force. The APEM MBZ101 series requires 285gf operating force. The E-Switch MS series offers variable operating force: MS0850500F060S1A (60gf), MS0850500F080S1A (80gf), MS0850500F250S1A (250gf), and MS0850500F295S1A (295gf). Operating force selection depends on the mechanical actuation requirements of the application.

Q: What packaging options are available for substitute parts?

A: The 41SM1 is supplied in Bulk packaging. The APEM MBZ101A01C01X01 and MBZ101A01C02X01 are supplied in Tray packaging. All E-Switch MS0850500 variants are supplied in Bulk packaging.

Q: How do the operating temperature ranges compare?

A: The 141SM102 operates from -55°C to 125°C. The 41SM1 maintains this full range. The APEM MBZ101 series operates from -40°C to 85°C. The E-Switch MS series operates from -25°C to 85°C. Application temperature requirements determine which substitutes are suitable.

Q: What is the mechanical life difference between the 141SM102 and substitutes?

A: The 141SM102 is rated for 80,000 mechanical cycles. The 41SM1 matches this specification. The APEM MBZ101 series is rated for 10,000,000 cycles. The E-Switch MS series is rated for 1,000,000 cycles. Higher mechanical life ratings indicate greater durability for high-cycle applications.
