AS22CP Equivalent & Substitute Parts

Part Overview

The AS22CP is an active DPDT slide switch manufactured by NKK Switches, designed for through-hole mounting applications requiring 0.4VA switching capacity at 28V. This component is a standard electromechanical switch suitable for control circuits and signal routing in industrial and consumer electronics. The part is actively produced and widely available in inventory (718 units in stock). Equivalent and substitute parts may be required due to supply chain constraints, design revisions, or specific application requirements that demand alternative electrical or mechanical characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AS22CP is determined by the following critical parameters:

• Circuit configuration must be DPDT
• Switch function must be On-On
• Current rating must be 0.4VA (AC/DC)
• Mounting type must be Through Hole
• Termination style must be PC Pin
• Voltage rating must support the application requirement (minimum 20V for both AC and DC)
• Contact timing should be Non-Shorting (BBM) for equivalent functionality
• RoHS3 compliance is required for regulatory alignment

The substitute parts ES21MCBE and TSS21NGPC meet the core electrical and mechanical requirements. However, voltage ratings differ from the main part: both substitutes are rated at 20V maximum, which is lower than the AS22CP's 28V rating. This represents a functional limitation that must be evaluated against specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

AS22CP (NKK Switches): Primary selection for applications requiring 28V operation. ROHS3 compliant with active product status. Supports full operating temperature range of -30°C to 85°C. Mechanical and electrical life rated at 50,000 cycles. Suitable for standard industrial control applications.

ES21MCBE (C&K): Applicable for applications operating at 20V or lower. ROHS3 compliant with active product status. Identical operating temperature range to the main part. Mechanical and electrical life rated at 40,000 cycles, representing a 20% reduction compared to AS22CP. Contact timing specification is not provided. REACH status is affected, requiring compliance verification for specific markets.

TSS21NGPC (TE Connectivity ALCOSWITCH): Applicable for applications operating at 20V or lower. RoHS status is not applicable; REACH status is vendor undefined. Operating temperature range is -20°C to 80°C, which is narrower than the main part. Mechanical and electrical life rated at 60,000 cycles, exceeding the AS22CP specification. Packaging is bulk format rather than tray. Non-Shorting (BBM) contact timing matches the main part specification.

Frequently Asked Questions (FAQ)

Q: Can ES21MCBE or TSS21NGPC be used in place of AS22CP in a 28V circuit?

A: No. Both substitute parts are rated for maximum 20V operation. Using them in a 28V circuit exceeds their voltage specification and may result in contact degradation or failure. Substitution is only valid for applications operating at 20V or lower.

Q: What is the difference in mechanical life between these parts?

A: AS22CP and ES21MCBE are rated for 50,000 and 40,000 cycles respectively. TSS21NGPC is rated for 60,000 cycles. Selection should be based on the expected number of switch actuations over the product lifetime.

Q: Are all three parts RoHS3 compliant?

A: AS22CP and ES21MCBE are ROHS3 compliant. TSS21NGPC has RoHS status listed as not applicable. For applications requiring RoHS3 compliance, AS22CP or ES21MCBE are the appropriate selections.

Q: What is the difference in packaging between these parts?

A: AS22CP and ES21MCBE are supplied in tray packaging. TSS21NGPC is supplied in bulk packaging. Packaging selection may affect handling, storage, and assembly processes.

Q: Does ES21MCBE have the same contact timing as AS22CP?

A: ES21MCBE contact timing is not specified in the available data. AS22CP and TSS21NGPC both specify Non-Shorting (BBM) contact timing. For applications sensitive to contact timing characteristics, TSS21NGPC provides confirmed equivalence.

Q: What is the operating temperature difference between these parts?

A: AS22CP and ES21MCBE support -30°C to 85°C. TSS21NGPC supports -20°C to 80°C. For applications requiring operation below -20°C or above 80°C, AS22CP or ES21MCBE are required.
