M505012 Equivalent & Substitute Parts

Part Overview

The M505012 is a 50A 600V SCR power module manufactured by Sensata-Crydom, featuring a single-phase bridge configuration with integrated SCRs and diodes for chassis mount applications. This component is classified as obsolete, making identification of active equivalent parts essential for ongoing system support and new design implementations. The M505012 series operates across industrial temperature ranges (-40°C to 125°C) and is suitable for high-current thyristor switching applications requiring 600V off-state voltage capability.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the M505012 is determined by strict equivalence across the following critical parameters:

• Voltage rating (600V off-state)
• Current capacity (50A nominal)
• Bridge configuration (single-phase SCRs/Diodes Layout 1)
• Component count (2 SCRs, 2 Diodes)
• Gate trigger specifications (Vgt ≤ 3V, Igt ≤ 150mA)
• Surge current capability (600A @ 60Hz)
• Operating temperature range (-40°C to 125°C)
• Mounting interface (Chassis Mount Module)

The M505012F qualifies as a direct substitute based on identical electrical specifications and mechanical configuration within the M50 series. The primary distinction is product status: M505012F is active production, whereas M505012 is obsolete.

Parameter Comparison

Engineering Selection Recommendations

The M505012F is the direct active equivalent for the obsolete M505012. Selection between these parts is determined by availability and product lifecycle requirements:

• M505012F is recommended for new designs and ongoing production. This part maintains active product status with ROHS3 compliance and REACH affected designation, ensuring long-term supply chain viability and regulatory alignment.

• M505012 remains available in inventory (966 pcs) for legacy system maintenance and repair applications where original part specifications are required. This part carries REACH unaffected status and is suitable for non-regulated applications.

Both parts are electrically and mechanically identical across all specified parameters. Selection should be based on product lifecycle phase, regulatory compliance requirements, and supply chain strategy rather than technical performance differences.

Frequently Asked Questions (FAQ)

Q: Can M505012F directly replace M505012 in existing applications?

A: Yes. The M505012F is electrically and mechanically equivalent to M505012 across all specified parameters including voltage rating, current capacity, gate trigger specifications, and operating temperature range. The parts are interchangeable from a functional standpoint.

Q: What is the primary difference between M505012 and M505012F?

A: The M505012 is classified as obsolete, while M505012F is active production. M505012F also carries ROHS3 compliance and REACH affected status, whereas M505012 is REACH unaffected. These differences reflect product lifecycle and regulatory positioning rather than electrical or mechanical changes.
