AS23BH/328 Equivalent & Substitute Parts

Part Overview

The AS23BH/328 is a slide switch manufactured by NKK Switches, configured as a DPDT (Double Pole Double Throw) switch with On-Off-On functionality. This component is rated for 0.4VA at 28V AC/DC and features a through-hole, right-angle mounting configuration with gold-plated phosphor bronze contacts. The AS23BH/328 is currently classified as obsolete, making identification of equivalent substitute parts essential for ongoing system maintenance and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the AS23BH/328 is determined by strict equivalence across the following critical parameters:

• Circuit configuration (DPDT)
• Switch function (On-Off-On)
• Electrical ratings (0.4VA at 28V AC/DC)
• Contact timing specification (Non-Shorting BBM)
• Mounting configuration (Through Hole, Right Angle)
• Termination style (PC Pin)
• Contact material and finish (Phosphor Bronze, Gold)
• Operating temperature range (-30°C to 85°C)
• Mechanical and electrical life ratings (50,000 cycles each)

The AS23BH represents a direct substitute for the AS23BH/328, maintaining identical electrical and mechanical specifications while differing only in packaging format and product status.

Parameter Comparison

Engineering Selection Recommendations

The AS23BH serves as the direct functional equivalent to the AS23BH/328. Both components are manufactured by NKK Switches within the AS series and maintain identical electrical and mechanical specifications. The primary distinction is product status: the AS23BH/328 is obsolete, while the AS23BH is active and currently in production.

For new designs or component replacement, the AS23BH is the appropriate selection. This part maintains full compatibility with applications originally specified for the AS23BH/328, with no modification to circuit design or PCB layout required. The AS23BH carries ROHS3 compliance certification, meeting current regulatory requirements for electronic components.

Frequently Asked Questions (FAQ)

Q: Can the AS23BH directly replace the AS23BH/328 in existing applications?

A: Yes. Both parts are electrically and mechanically identical. The AS23BH maintains the same DPDT circuit configuration, 0.4VA/28V rating, non-shorting contact timing, through-hole right-angle mounting, and PC pin termination. No circuit modifications are required.

Q: What is the difference between the AS23BH/328 and AS23BH?

A: The components are functionally equivalent. The AS23BH/328 is obsolete and supplied in tube packaging, while the AS23BH is active and supplied in tray packaging. All electrical and mechanical parameters are identical.

Q: Are there packaging considerations when switching from AS23BH/328 to AS23BH?

A: Yes. The AS23BH/328 is packaged in tubes, while the AS23BH is packaged in trays. This affects handling and storage procedures but does not impact component performance or compatibility.

Q: Does the AS23BH meet current compliance standards?

A: The AS23BH is ROHS3 compliant and maintains REACH unaffected status. Both parts carry EAR99 ECCN classification and the same HTSUS code (8536.50.9050).

Q: What is the operating temperature range for these components?

A: Both the AS23BH/328 and AS23BH operate across -30°C to 85°C, with mechanical and electrical life rated at 50,000 cycles under specified conditions.
