APEM 302SCNE Pushbutton Switch - Equivalent & Substitute Parts

Part Overview

The APEM 302SCNE is a panel-mounted pushbutton switch with SPST-NO (Single Pole Single Throw - Normally Open) circuit configuration. This component features a round plunger actuator with black cap, rear panel mounting, and PC pin termination. The product is currently obsolete, with 685 units available in original stock inventory. Due to its discontinued status, identifying active equivalent parts is essential for ongoing system maintenance and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 302SCNE is determined by the following critical parameters:

• Circuit Configuration: SPST-NO (mandatory match)
• Switch Function: Off-Mom momentary operation (mandatory match)
• Mounting Type: Panel Mount, Rear (mandatory match)
• Actuator Type: Round, Plunger (mandatory match)
• Actuator Color: Black (mandatory match)
• Panel Cutout Dimensions: Circular - 6.35mm Dia (mandatory match)
• Termination Style: PC Pin (mandatory match)
• Operating Temperature Range: -30°C ~ 85°C (mandatory match)
• Series: 300 (mandatory match)
• RoHS Compliance: ROHS3 Compliant (mandatory match)

The APEM 302SCBE qualifies as a direct substitute based on full alignment with all mandatory parameters. The 302SCBE maintains identical mechanical and electrical interface specifications while offering active product status and extended electrical life rating of 250,000 cycles.

Engineering Selection Recommendations

The APEM 302SCBE is the qualified substitute for the obsolete 302SCNE. Selection of the 302SCBE is supported by the following factors:

• Product Status: The 302SCBE maintains active manufacturing status, ensuring long-term availability and supply chain continuity.
• Regulatory Compliance: Both parts maintain identical ROHS3 compliance and REACH unaffected status, satisfying current environmental and regulatory requirements.
• Interface Compatibility: Mechanical and electrical interfaces are fully preserved, including panel cutout dimensions, termination style, and operating temperature specifications.
• Electrical Performance: The 302SCBE provides specified electrical ratings (0.4VA at 20V AC/DC) and documented electrical life of 250,000 cycles, establishing quantified performance parameters absent from the obsolete part.

Frequently Asked Questions (FAQ)

Q: Can the 302SCBE be used as a direct replacement for the 302SCNE in existing designs?

A: Yes. The 302SCBE maintains identical mechanical mounting specifications (6.35mm circular panel cutout, rear panel mount), electrical interface (PC pin termination), and functional characteristics (SPST-NO, Off-Mom operation). No design modifications are required for panel cutout or wiring harness interfaces.

Q: What are the electrical operating limits of the 302SCBE?

A: The 302SCBE is rated for 0.4VA at 20V AC or DC. Applications requiring higher current or voltage ratings require evaluation of alternative part numbers within the APEM 300 series.

Q: Are there differences in packaging between the 302SCNE and 302SCBE?

A: Packaging information is not specified for either part number. Contact APEM Inc. directly for packaging and quantity per reel specifications if required for automated assembly processes.

Q: Does the 302SCBE meet the same environmental specifications as the 302SCNE?

A: Yes. Both parts operate across the identical temperature range (-30°C ~ 85°C), maintain MSL 1 (Unlimited) moisture sensitivity rating, and comply with ROHS3 and REACH requirements.

Q: What is the mechanical life expectancy of the 302SCBE?

A: Mechanical life is not specified in the available technical data. Electrical life is documented at 250,000 cycles. For detailed mechanical life specifications, consult APEM Inc. technical documentation.
