ATE1FGRA1 Equivalent & Substitute Parts

Part Overview

The ATE1FGRA1 is a toggle switch manufactured by TE Connectivity ALCOSWITCH Switches, configured as a Single Pole Double Throw (SPDT) momentary contact switch with a 0.4VA current rating at 20V. The switch features through-hole right-angle mounting with a 6.00mm standard round actuator and PC pin termination. This component is classified as obsolete, necessitating identification of equivalent substitute parts for ongoing design requirements and procurement needs.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ATE1FGRA1 are identified based on strict electrical and mechanical compatibility criteria. The following parameters must align for valid substitution:

Critical Matching Parameters:

• Circuit configuration: SPDT
• Current rating: 0.4VA (AC/DC)
• Voltage rating: 20V AC and 20V DC
• Termination style: PC Pin
• Actuator type: Standard Round
• Mounting type: Through Hole

Allowable Variations:

• Actuator length may differ (6.00mm to 10.16mm) provided mechanical clearance is verified in the application
• Switch function may vary between On-Mom and On-On configurations depending on circuit requirements
• Operating temperature range may be extended without affecting substitution validity
• Electrical life ratings may exceed the original specification
• RoHS and REACH compliance status may differ based on regulatory requirements

The identified substitute parts ET08SD1CBE and ET01SD1ABE satisfy all critical electrical parameters and mounting requirements while offering enhanced environmental protection and compliance certifications.

Engineering Selection Recommendations

ET08SD1CBE (Primary Substitute for On-Mom Applications)

The ET08SD1CBE is the direct functional equivalent for applications requiring momentary contact operation. This C&K toggle switch maintains identical electrical specifications (SPDT, 0.4VA, 20V) and PC pin termination. The part is currently in active production status, ensuring long-term availability. The ET08SD1CBE provides ROHS3 compliance, addressing regulatory requirements that the obsolete ATE1FGRA1 does not meet. Enhanced ingress protection (IP57) and extended operating temperature range (-30°C to 85°C) provide improved environmental performance. The increased electrical life rating of 30,000 cycles extends component reliability compared to the original 10,000-cycle specification. The 10.16mm actuator length requires mechanical clearance verification in the application enclosure.

ET01SD1ABE (Alternative for On-On Applications)

The ET01SD1ABE functions as a substitute when circuit design permits On-On (maintained contact) operation instead of momentary contact. This part shares identical electrical ratings and termination style with the ATE1FGRA1. The ET01SD1ABE offers the highest electrical life rating at 60,000 cycles and maintains ROHS3 compliance with IP57 ingress protection. The extended operating temperature range and active product status support long-term procurement. Selection of this part requires confirmation that the application circuit design accommodates On-On switch function rather than momentary operation.

Mechanical Considerations

Both substitute parts feature 10.16mm actuators compared to the original 6.00mm length. Panel cutout dimensions and mechanical mounting clearances must be evaluated for the specific application. Through-hole mounting compatibility is maintained across all three parts.

Frequently Asked Questions (FAQ)

Q: Can ET08SD1CBE directly replace ATE1FGRA1 in existing designs?

A: The ET08SD1CBE provides electrical and functional equivalence for momentary contact applications. The primary consideration is the increased actuator length (10.16mm versus 6.00mm), which requires verification of mechanical clearance within the application enclosure. All electrical parameters, circuit configuration, and termination style are compatible.

Q: What is the difference between ET08SD1CBE and ET01SD1ABE?

A: Both parts share identical electrical specifications and mounting characteristics. The primary difference is switch function: ET08SD1CBE operates as On-Mom (momentary), while ET01SD1ABE operates as On-On (maintained contact). ET01SD1ABE also provides superior electrical life (60,000 cycles versus 30,000 cycles). Selection depends on circuit requirements for momentary or maintained contact operation.

Q: Are the substitute parts RoHS compliant?

A: Both ET08SD1CBE and ET01SD1ABE are ROHS3 compliant, addressing regulatory requirements that the obsolete ATE1FGRA1 does not satisfy. This compliance status is relevant for applications subject to RoHS directives.

Q: What is the significance of IP57 ingress protection on the substitute parts?

A: The IP57 rating indicates dust protection and waterproof operation, providing enhanced environmental performance compared to the original ATE1FGRA1. This specification is relevant only if the application environment requires such protection. Standard indoor applications may not require this enhanced rating.

Q: How does the extended operating temperature range affect substitution?

A: Both substitute parts operate across -30°C to 85°C, compared to the original -20°C to 80°C range. This extended range provides additional margin for applications operating at temperature extremes. The extended range does not restrict substitution in applications within the original temperature specification.

Q: Is the increased electrical life rating of the substitute parts significant?

A: The ET08SD1CBE provides 30,000 cycles and ET01SD1ABE provides 60,000 cycles, compared to 10,000 cycles for the ATE1FGRA1. Higher electrical life ratings indicate extended component reliability and reduced failure risk in high-cycle applications. Applications with lower cycle requirements are unaffected by this difference.

Q: What packaging format is available for the substitute parts?

A: Both ET08SD1CBE and ET01SD1ABE are supplied in bulk packaging. Inventory availability is confirmed at 867 pieces for ET08SD1CBE and 800 pieces for ET01SD1ABE.
