APEM Inc. 13235A Pushbutton Switch SPDT Equivalent & Substitute Parts

Part Overview

The APEM Inc. 13235A is an active-status SPDT pushbutton switch rated for 4A at 125V AC and 30V DC. This panel-mount rear component features a plunger actuator with PC pin termination and operates across -40°C to 85°C with 150,000 mechanical cycles and 50,000 electrical cycles. The part is ROHS3 compliant and MSL 1 rated. Substitute parts may be required due to inventory constraints, application-specific voltage or current requirements, or packaging format preferences.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 13235A is determined by the following critical parameters: circuit configuration (SPDT), switch function (On-Mom), mounting type (Panel Mount, Rear), termination style (PC Pin), and RoHS3 compliance. Current and voltage ratings establish application boundaries; substitutes must meet or exceed the electrical requirements of the target application. Operating temperature range, mechanical life, and electrical life define performance envelope compatibility. All identified substitutes maintain SPDT configuration, On-Mom function, panel-mount rear installation, and PC pin termination. Packaging format (Bulk vs. Tray) and actuator color variations do not affect electrical substitutability but may influence procurement and assembly workflows.

Parameter Comparison

Engineering Selection Recommendations

C&K 8168SHCGE2: This substitute provides the highest current rating (6A AC/DC) and maintains 120V AC / 28V DC voltage specifications. It is suitable for applications requiring equal or greater current capacity than the 13235A. Operating temperature range is reduced to -30°C to 65°C. Packaging is supplied in Tray format. ROHS3 compliance and MSL 1 rating are maintained.

C&K 8121SDCGE: This substitute is rated for 1A AC/DC at 120V AC / 28V DC. It is suitable only for low-current applications where the 13235A's 4A rating exceeds system requirements. Operating temperature range is -30°C to 75°C with electrical life of 60,000 cycles. Bulk packaging is provided. ROHS3 compliance and MSL 1 rating are maintained.

C&K 8125SDCBE: This substitute is rated for 0.4VA at 20V AC/DC. It is suitable only for very low-voltage, low-current applications and does not meet the electrical specifications of the 13235A for standard industrial use. Operating temperature range is -30°C to 75°C. Bulk packaging is provided. ROHS3 compliance and MSL 1 rating are maintained.

All substitutes maintain active product status and full regulatory compliance. Selection must be based on application voltage and current requirements.

Frequently Asked Questions (FAQ)

Q: Can the C&K 8168SHCGE2 directly replace the APEM 13235A in all applications?

A: The 8168SHCGE2 is electrically compatible for applications operating at or below 120V AC and 28V DC with current draw at or below 6A. However, the reduced operating temperature range (-30°C to 65°C versus -40°C to 85°C) must be verified against application requirements. Packaging format differs (Tray vs. Bulk).

Q: Is the C&K 8121SDCGE suitable as a substitute for the 13235A?

A: The 8121SDCGE maintains SPDT configuration, On-Mom function, and panel-mount rear installation. However, its 1A current rating is significantly lower than the 13235A's 4A rating. It is suitable only for applications where current demand does not exceed 1A. Voltage ratings (120V AC / 28V DC) are comparable.

Q: What are the limitations of the C&K 8125SDCBE?

A: The 8125SDCBE is rated for only 0.4VA at 20V AC/DC, making it unsuitable for most applications requiring the 13235A's 4A / 125V AC specifications. It is applicable only to very low-power control circuits.

Q: Do all substitutes maintain RoHS3 and MSL 1 compliance?

A: Yes. All three C&K substitutes (8168SHCGE2, 8121SDCGE, 8125SDCBE) are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, matching the 13235A.

Q: How does packaging format affect substitutability?

A: The 13235A and 8121SDCGE / 8125SDCBE are supplied in Bulk packaging. The 8168SHCGE2 is supplied in Tray packaging. Packaging format does not affect electrical substitutability but may influence procurement lead times, storage requirements, and assembly line integration.

Q: Are there temperature range considerations for substitute selection?

A: The 13235A operates from -40°C to 85°C. All C&K substitutes have narrower ranges (-30°C to 75°C or -30°C to 65°C). Applications requiring operation below -30°C or above 75°C must use the 13235A or verify substitute compatibility with specific temperature extremes.
