AB15CH Equivalent & Substitute Parts

Part Overview

The AB15CH is an active pushbutton switch manufactured by NKK Switches, designed for standard through-hole, right-angle mounting applications. This SPDT (Single Pole Double Throw) switch operates at 0.4VA across 28V AC/DC with a sealed, fully-protected design suitable for industrial and commercial control circuits. The part is ROHS3 compliant and carries an unlimited moisture sensitivity level (MSL 1), making it suitable for general-purpose switching applications requiring reliable mechanical and electrical performance over extended operational life.

Equivalent and substitute parts are identified to support procurement flexibility, inventory management, and supply chain continuity when the primary AB15CH becomes unavailable or when application requirements necessitate alternative specifications within compatible electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AB15CH is determined by the following critical parameters:

Circuit Configuration & Function: Both the main part and substitute must maintain SPDT circuit topology with On-Mom (momentary) switching function to ensure functional compatibility within existing control circuits.

Mounting & Termination: Through-hole, right-angle mounting with PC pin termination is required to maintain mechanical fit and electrical connection compatibility with printed circuit board layouts designed for the AB15CH.

Actuator Type: Round plunger actuators ensure consistent user interface and mechanical engagement characteristics across substitute selections.

Operating Temperature Range: The -30°C ~ 85°C operating window must be maintained or exceeded to ensure reliable operation across the intended environmental conditions.

Electrical Life & Mechanical Life: Minimum 50,000 cycles for both electrical and mechanical life ensures equivalent durability and reliability performance.

Compliance & Certifications: ROHS3 compliance and MSL 1 rating are mandatory to meet regulatory requirements and ensure compatibility with modern manufacturing and storage conditions.

The substitute part 800AWSP8M6QE from E-Switch meets these core substitution criteria while offering enhanced ingress protection (IP67) and higher current capacity (1A AC versus 0.4VA), making it suitable for applications requiring greater electrical headroom or environmental sealing.

Parameter Comparison

Engineering Selection Recommendations

Both the AB15CH and 800AWSP8M6QE are active products with ROHS3 compliance and MSL 1 ratings, ensuring regulatory alignment and manufacturing compatibility. Selection between these parts should be based on application-specific electrical requirements:

The AB15CH is appropriate for applications operating at 28V AC/DC with current demands up to 0.4VA, where standard sealing is sufficient and cost optimization is a priority.

The 800AWSP8M6QE is suitable for applications requiring higher voltage tolerance (120V AC), increased current capacity (1A AC), or enhanced environmental protection (IP67 rating). The higher electrical ratings provide design margin for applications with variable load conditions or future specification changes.

Both parts share identical mechanical life specifications (50,000 cycles), operating temperature range (-30°C ~ 85°C), and circuit topology (SPDT On-Mom), ensuring functional interchangeability within the specified parameter boundaries.

Frequently Asked Questions (FAQ)

Q: Can the 800AWSP8M6QE directly replace the AB15CH in all applications?

A: Direct replacement is possible when the application operates at or below 28V AC/DC and does not exceed 0.4VA current draw. The 800AWSP8M6QE's higher voltage and current ratings (120V AC, 1A AC) provide design margin but do not restrict operation at lower specifications. Mechanical fit and termination compatibility are identical, ensuring PCB-level interchangeability.

Q: What is the significance of the IP67 rating on the 800AWSP8M6QE?

A: IP67 (Dust Tight, Waterproof) provides enhanced environmental protection compared to the AB15CH's standard sealing. This rating is relevant only if the application environment includes moisture, dust ingress, or submersion requirements. For standard indoor control applications, this feature provides additional margin but is not functionally necessary.

Q: Are both parts suitable for the same operating temperature range?

A: Yes. Both the AB15CH and 800AWSP8M6QE operate across -30°C ~ 85°C, ensuring equivalent thermal performance across industrial and commercial temperature environments.

Q: What packaging considerations apply to these parts?

A: Both parts are supplied in bulk packaging. The AB15CH has 826 pieces in current inventory, while the 800AWSP8M6QE has 1183 pieces available. Packaging format does not affect electrical or mechanical compatibility; selection should be based on procurement quantity requirements and lead time availability.

Q: Do both parts meet current regulatory compliance requirements?

A: Yes. Both the AB15CH and 800AWSP8M6QE are ROHS3 compliant and carry MSL 1 (Unlimited) ratings, meeting current environmental and manufacturing standards for electronic components.
