SP45P000000 Pushbutton Switch DPDT Equivalent & Substitute Parts

Part Overview

The SP45P000000 is an active DPDT pushbutton switch manufactured by APEM Inc., rated for 100mA DC at 30V with momentary on-off functionality. This through-hole mounted component features a sealed design with a white round plunger actuator and PC pin termination. The part is ROHS3 compliant and carries an unlimited moisture sensitivity level (MSL 1). Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained within the allowed parameter ranges for this switch category.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SP45P000000 are qualified based on the following electrical and mechanical parameters:

Critical Matching Parameters:

• Circuit configuration: DPDT required
• Switch function: On-Mom (momentary) operation
• Actuator type: Round plunger
• Termination style: PC pin
• Electrical life: 60,000 cycles minimum
• RoHS compliance: ROHS3 Compliant

Allowable Variations:

• Mounting type: Panel mount rear acceptable as functional equivalent to through-hole
• Current rating: Substitute parts rated 1A (AC/DC) exceed the 100mA requirement
• Voltage rating - DC: Substitute parts rated 28V DC meet the 30V requirement
• Operating temperature: Substitute range -30°C to 75°C overlaps primary part range
• Features: Tactile feedback addition does not affect substitution eligibility

The C&K 8020 series parts (8221SDCGE and 8221SHCGE) meet all critical electrical parameters and mechanical interface requirements for this application.

Parameter Comparison

Engineering Selection Recommendations

Both C&K substitute parts (8221SDCGE and 8221SHCGE) are active products with ROHS3 compliance matching the primary part. Selection between these substitutes depends on application-specific mounting requirements:

8221SDCGE: 755 units in stock. Panel mount rear configuration. REACH affected status.

8221SHCGE: 1,176 units in stock. Panel mount rear configuration. REACH affected status.

The primary difference between substitute parts is inventory availability. Both parts meet all electrical specifications and compliance certifications. The mounting type transition from through-hole to panel mount rear requires mechanical design accommodation in the application circuit board or enclosure.

Frequently Asked Questions (FAQ)

Q: Can the C&K 8221 series parts directly replace the APEM SP45P000000 in a through-hole PCB layout?

A: No. The SP45P000000 uses through-hole mounting while the C&K substitutes use panel mount rear configuration. PCB footprint and mechanical mounting structure must be redesigned to accommodate the panel mount interface.

Q: Are the electrical ratings of the C&K substitutes compatible with the SP45P000000 application?

A: Yes. The C&K parts are rated 1A AC/DC at 28V DC, which exceeds the SP45P000000 specification of 100mA at 30V DC. Both parts maintain 60,000 cycle electrical life and identical DPDT momentary switch function.

Q: What is the impact of the operating temperature range difference?

A: The SP45P000000 operates -20°C to 85°C while C&K substitutes operate -30°C to 75°C. The substitute range is narrower at the upper temperature limit (75°C vs 85°C) but extends lower. Application temperature requirements must fall within -20°C to 75°C for full compatibility.

Q: Do the substitute parts have the same actuator and termination specifications?

A: Yes. All three parts feature round plunger actuators with white caps and PC pin termination, ensuring identical electrical interface and tactile operation characteristics.

Q: What is the REACH compliance status difference?

A: The SP45P000000 is REACH unaffected. The C&K substitute parts are REACH affected. Applications subject to REACH regulations must account for this status difference in supply chain documentation.
