8A2012C-Z Toggle Switch DPDT Equivalent & Substitute Parts

Part Overview

The 8A2012C-Z is a panel-mounted toggle switch with DPDT (Double Pole Double Throw) configuration manufactured by Nidec Components Corporation. This component is classified as obsolete, with 986 units currently in stock. The switch is designed for low-voltage DC applications with a maximum rating of 25mA at 20V DC. Due to its obsolete status, identifying functionally equivalent substitute parts is essential for ongoing system maintenance and new design implementations where similar switching functionality is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 8A2012C-Z is determined by the following critical parameters:

Mechanical Compatibility:

• Panel mount configuration with identical 6.50mm circular cutout diameter
• 1/4-40 bushing thread specification
• Standard round actuator with 10.50mm length
• PC pin termination style

Electrical Compatibility:

• DPDT circuit configuration (two independent poles, two throw positions each)
• On-On switch function
• Sealed flux protection feature
• Operating temperature range capability

Regulatory Compliance:

• ROHS3 compliance requirement
• Moisture Sensitivity Level 1 classification

The 8A2012-Z qualifies as a substitute part within the 8A series, sharing identical mechanical mounting specifications, circuit topology, and regulatory compliance status. Electrical parameter differences exist in current and voltage ratings, which must be evaluated against specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

The 8A2012-Z is an active-status substitute for the obsolete 8A2012C-Z within the Nidec 8A series. Both components maintain identical mechanical interfaces and ROHS3 compliance certification, ensuring direct panel-mount compatibility without mechanical redesign.

The 8A2012-Z provides higher electrical ratings (4A DC at 30V, 6A AC at 125V) compared to the 8A2012C-Z (25mA DC at 20V). This rating differential permits the substitute to function in applications matching or exceeding the original part's electrical requirements. The extended operating temperature range (-30°C to 85°C versus -20°C to 85°C) provides additional environmental margin.

Selection of the 8A2012-Z is appropriate for applications where the original 8A2012C-Z is no longer procurable and electrical load requirements do not exceed the substitute's ratings. The active product status of the 8A2012-Z ensures ongoing availability and supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can the 8A2012-Z directly replace the 8A2012C-Z in existing assemblies?

A: Mechanical and electrical compatibility exists for direct substitution. The 8A2012-Z maintains identical panel cutout dimensions (6.50mm circular), bushing thread (1/4-40), actuator geometry (10.50mm standard round), and PC pin termination. Both components feature DPDT On-On configuration with sealed flux protection. Substitution is valid when application current and voltage requirements do not exceed 4A DC at 30V or 6A AC at 125V.

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

A: The 8A2012C-Z is rated for 25mA DC at 20V DC. The 8A2012-Z is rated for 4A DC at 30V DC and 6A AC at 125V AC. The substitute part provides significantly higher current and voltage capacity. Applications operating within the original part's 25mA/20V specification will function within the substitute's ratings.

Q: Are there packaging differences between these parts?

A: The 8A2012C-Z is supplied in standard packaging. The 8A2012-Z is supplied in bulk packaging. Both maintain identical component specifications and mechanical form factors.

Q: Do both parts meet the same regulatory requirements?

A: Both the 8A2012C-Z and 8A2012-Z are ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited). Regulatory compliance is equivalent between the two parts.

Q: What is the operational temperature difference?

A: The 8A2012C-Z operates from -20°C to 85°C. The 8A2012-Z operates from -30°C to 85°C. The substitute provides a 10°C lower temperature limit, extending the operational envelope for cold-environment applications.

Q: Why is the 8A2012C-Z classified as obsolete?

A: Obsolete status indicates the part is no longer in active production. The 8A2012-Z, as an active-status component within the same series, provides functional continuity for ongoing system support and new designs.
