ES03MAKE Equivalent & Substitute Parts Reference

Part Overview

The ES03MAKE is a slide switch manufactured by C&K, featuring SPDT (Single Pole Double Throw) configuration with 0.4VA current rating and 20V voltage rating. This component is classified as obsolete, making identification of equivalent substitute parts essential for design continuity and procurement planning. The switch is designed for through-hole, right-angle mounting applications with epoxy sealed terminals rated to IP57.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ES03MAKE is determined by strict alignment with the following core parameters:

• Circuit configuration must be SPDT
• Current rating must support 0.4VA (AC/DC) minimum
• Voltage rating must meet or exceed 20V (AC and DC)
• Switch function must be On-Off-On
• Mounting type must be through-hole, right-angle configuration
• Termination style must be PC Pin
• Epoxy sealed terminals required

The identified substitute parts meet these mandatory criteria. Variations in secondary parameters such as actuator length, switch travel, mechanical life, and operating force do not preclude substitution when core electrical and mechanical requirements are satisfied.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts satisfy the core electrical and mechanical requirements of the ES03MAKE. Selection between them depends on regulatory and compliance requirements:

The 1571984-2 (TE Connectivity) maintains electrical parity with the original part at 20V rating and provides enhanced mechanical durability with 60,000 cycle life. However, RoHS compliance status is not applicable, and REACH status is vendor-undefined, requiring clarification for regulated applications.

The AS13AH (NKK Switches) offers superior voltage rating at 28V, extended mechanical life of 50,000 cycles, and full ROHS3 compliance with REACH unaffected status. This part is suitable for applications requiring regulatory compliance documentation and higher voltage margin.

For applications without specific compliance mandates, either substitute provides functional equivalence. For regulated or safety-critical applications, the AS13AH is the preferred selection due to established compliance certifications.

Frequently Asked Questions (FAQ)

Q: Can the 1571984-2 be used as a direct replacement for ES03MAKE?

A: Yes. Both parts share identical SPDT circuit configuration, 0.4VA current rating, 20V voltage rating, On-Off-On function, through-hole right-angle mounting, and PC pin termination. The 1571984-2 is an active product with enhanced mechanical life specifications.

Q: What is the voltage difference between ES03MAKE and AS13AH?

A: The ES03MAKE is rated for 20V (AC/DC), while the AS13AH is rated for 28V (AC/DC). The higher voltage rating of the AS13AH provides additional design margin and does not prevent substitution in 20V applications.

Q: Are there packaging differences between these parts?

A: Yes. The ES03MAKE is supplied in standard packaging, the 1571984-2 in bulk packaging, and the AS13AH in tray packaging. Packaging format does not affect electrical or mechanical compatibility.

Q: Which substitute part has better compliance documentation?

A: The AS13AH provides ROHS3 compliance certification and REACH unaffected status. The 1571984-2 has not applicable RoHS status and vendor-undefined REACH status. For regulated applications, the AS13AH offers clearer compliance documentation.

Q: Do actuator length differences affect substitution?

A: Actuator length variations (ES03MAKE: 3.07mm, 1571984-2: 2.79mm, AS13AH: 2.50mm) are secondary parameters that do not preclude substitution. Physical fit must be verified against specific PCB layout and mechanical envelope requirements.

Q: What is the contact timing specification for the substitute parts?

A: Both substitute parts feature non-shorting (BBM) contact timing, which is a performance enhancement compared to the ES03MAKE specification where contact timing is not specified.
