Toggle Switch DP3T 8A4111-Z Equivalent & Substitute Parts

Part Overview

The 8A4111-Z is a panel-mount toggle switch manufactured by Nidec Components Corporation, configured as a DP3T (double-pole, triple-throw) switch with On-On-Mom functionality. This component is rated for 6A AC at 125V and 4A DC at 30V, featuring a standard round actuator with 10.50mm length and solder lug termination. The product is currently obsolete, making identification of functionally equivalent alternatives essential for system maintenance, repair, and redesign applications where continued component availability is required.

Key Parameters

Substitute Part Grouping Explanation

The 5664TH1RAB manufactured by APEM Inc. qualifies as a direct functional substitute for the 8A4111-Z based on the following critical parameters:

Matching Electrical Specifications:

• DP3T circuit configuration with On-On-Mom switching function
• Identical current ratings: 6A AC and 4A DC
• Identical voltage ratings: 125V AC and 30V DC

Matching Mechanical Specifications:

• Panel mount installation method
• Standard round actuator with 10.50mm length
• Circular panel cutout of 6.50mm diameter
• 1/4-40 bushing thread
• Solder lug termination style

Compliance Alignment:

• Both components are ROHS3 compliant
• Both carry EAR99 ECCN classification
• Both share identical HTSUS code 8536.50.9065

The 5664TH1RAB operates across an extended temperature range (-40°C ~ 85°C versus -20°C ~ 85°C) and provides increased electrical life (30,000 cycles versus 25,000 cycles), representing performance improvements over the obsolete original part.

Parameter Comparison

Engineering Selection Recommendations

The 5664TH1RAB is the qualified substitute for the obsolete 8A4111-Z. Both components maintain identical electrical and mechanical specifications across all critical parameters, ensuring direct functional compatibility in existing circuit designs and panel installations.

The 5664TH1RAB offers additional advantages: active product status ensures ongoing availability and supply chain continuity, extended operating temperature range provides broader environmental tolerance, and increased electrical life rating extends component service intervals. Both parts maintain equivalent regulatory compliance through ROHS3 certification and identical trade classification codes.

Selection of the 5664TH1RAB eliminates obsolescence risk while maintaining full electrical and mechanical interchangeability with the original 8A4111-Z specification.

Frequently Asked Questions (FAQ)

Q: Can the 5664TH1RAB directly replace the 8A4111-Z without circuit modification?

A: Yes. The 5664TH1RAB provides identical electrical ratings (6A AC at 125V, 4A DC at 30V), matching circuit configuration (DP3T On-On-Mom), and equivalent mechanical interface (panel mount, 6.50mm cutout, 1/4-40 bushing, solder lug termination). No circuit redesign is required.

Q: What are the key differences between these two parts?

A: The 5664TH1RAB operates across a wider temperature range (-40°C to 85°C versus -20°C to 85°C) and provides extended electrical life (30,000 cycles versus 25,000 cycles). The 8A4111-Z is obsolete; the 5664TH1RAB is an active product with current manufacturing support.

Q: Are both parts RoHS compliant?

A: Yes. Both the 8A4111-Z and 5664TH1RAB are ROHS3 compliant and carry identical HTSUS classification 8536.50.9065.

Q: What does the "Jumper needed to achieve triple throw" specification mean?

A: Both components require a jumper configuration to achieve full DP3T (triple-throw) functionality. This is a standard design feature for both the original and substitute part.

Q: Is the 5664TH1RAB available in the same packaging as the 8A4111-Z?

A: The 5664TH1RAB is supplied in bulk packaging. Verify packaging requirements for your application, as the original 8A4111-Z packaging specification was not provided in the technical data.
