SP35W000000 Pushbutton Switch SPDT Equivalent & Substitute Parts

Part Overview

The SP35W000000 is an APEM Inc. pushbutton switch featuring SPDT (Single Pole Double Throw) circuitry with On-Momentary function. This Through Hole, Right Angle mounted component is rated for 100mA DC at 30V with a sealed design and 60,000 electrical life cycles. The part is Active status and ROHS3 compliant, making it suitable for industrial and commercial applications requiring reliable momentary switching.

Equivalent and substitute parts are identified based on matching core electrical and mechanical parameters: SPDT circuit configuration, On-Momentary switching function, Through Hole Right Angle mounting, PC Pin termination, Round Plunger actuator, and compatible voltage/current operating ranges within sealed pushbutton switch designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SP35W000000 is determined by the following mandatory parameters:

• Circuit Configuration: SPDT only
• Switch Function: On-Momentary operation
• Mounting: Through Hole, Right Angle orientation
• Termination: PC Pin connection
• Actuator: Round Plunger type
• Voltage Compatibility: DC rating must support minimum 30V application requirement
• Current Compatibility: DC current rating must support minimum 100mA application requirement
• Sealing: Sealed design preferred for environmental protection
• Compliance: ROHS3 compliance required

Five substitute parts meet these criteria across two manufacturers (C&K). Substitutes are grouped by electrical rating capability: lower-rated sealed designs (E112SD1ABE), standard-rated designs with tactile feedback (8121SD9AGE, 8121SH9AGE), and higher-rated sealed designs (E112SD1A3QE, E112SD1AQE).

Parameter Comparison

Engineering Selection Recommendations

All five substitute parts are Active status products with ROHS3 compliance, meeting regulatory requirements equivalent to the SP35W000000.

E112SD1ABE (C&K E010 Series): Suitable for applications with lower voltage requirements (20V DC maximum). Current rating of 0.4VA is below the SP35W000000 requirement and limits application scope. Electrical life of 40,000 cycles is lower than the original part. Process Sealed design provides environmental protection. Tray packaging available.

8121SD9AGE and 8121SH9AGE (C&K 8020 Series): Both rated for 1A AC/DC at 28V DC, exceeding the SP35W000000 current requirement. Electrical life matches at 60,000 cycles. Tactile Feedback feature provides enhanced user feedback. Operating temperature range (-30°C to 75°C) is narrower than the original part at the upper limit. Tray packaging available. REACH Affected status noted.

E112SD1A3QE and E112SD1AQE (C&K E010 Series): Both rated for 4A AC/DC at 28V DC, providing significant current margin above the 100mA requirement. Process Sealed design ensures environmental protection. Electrical life of 40,000 cycles is lower than the original part. Operating temperature range (-30°C to 75°C) is narrower at the upper limit. Bulk packaging available for E112SD1A3QE and E112SD1AQE. REACH Unaffected status for E112SD1AQE.

Frequently Asked Questions (FAQ)

Q: Can E112SD1ABE replace SP35W000000 in all applications?

A: E112SD1ABE has a maximum DC voltage rating of 20V, which is below the SP35W000000 rating of 30V. This part is suitable only for applications operating at 20V DC or lower. Current rating of 0.4VA is also below the 100mA requirement. Verify application voltage and current demands before selection.

Q: What is the difference between the 8121SD9AGE and 8121SH9AGE?

A: Both parts share identical electrical specifications (1A AC/DC, 28V DC), mounting configuration, and actuator type. The primary difference is the base product number designation (8121SD versus 8121SH). Both provide 60,000 electrical life cycles and Tactile Feedback features. Selection between these parts depends on inventory availability and packaging requirements (both available in Tray).

Q: Are the higher-rated C&K E010 parts (E112SD1A3QE, E112SD1AQE) direct replacements?

A: These parts meet all core substitution criteria: SPDT circuit, On-Momentary function, Through Hole Right Angle mounting, PC Pin termination, and Round Plunger actuator. Current rating of 4A AC/DC exceeds the 100mA requirement. DC voltage rating of 28V is slightly below the original 30V specification. Electrical life of 40,000 cycles is lower than the SP35W000000 at 60,000 cycles. Confirm application voltage does not exceed 28V DC and that reduced cycle life is acceptable for the intended use.

Q: What packaging options are available for substitutes?

A: E112SD1ABE, 8121SD9AGE, and 8121SH9AGE are supplied in Tray packaging. E112SD1A3QE and E112SD1AQE are supplied in Bulk packaging, matching the original SP35W000000 packaging format.

Q: Do all substitute parts meet RoHS compliance?

A: All five substitute parts are ROHS3 compliant, matching the regulatory status of SP35W000000. REACH status varies: 8121SD9AGE and 8121SH9AGE are REACH Affected; E112SD1ABE, E112SD1A3QE, and E112SD1AQE are REACH Unaffected.

Q: Which substitute offers the closest electrical life match?

A: 8121SD9AGE and 8121SH9AGE both provide 60,000 electrical life cycles, matching the SP35W000000 specification exactly. E112SD1ABE, E112SD1A3QE, and E112SD1AQE are rated for 40,000 cycles, representing a 33% reduction in cycle life.
