Sensata-Crydom 6351 DC Output Module - Equivalent & Substitute Parts

Part Overview

The Sensata-Crydom 6351 is a DC output module rated for 4.6A continuous output current with a 15VDC supply input. This module provides isolated DC switching capability across a 3 to 60VDC output range and features hold-down screw mounting. The 6351 is classified as obsolete, making identification of active equivalent parts essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Sensata-Crydom 6351 is determined by electrical and mechanical parameter matching:

Critical Matching Parameters:

• Output current rating: 4.6A
• Output voltage range: 3 ~ 60VDC
• Input supply voltage: 15VDC
• Mechanical interface: Hold-down screw mounting
• Module type: DC output switching module

The Grayhill Inc. 70-ODC15 satisfies all critical electrical parameters and mechanical requirements. While input current consumption differs (9 mA versus 25 mA), this represents improved efficiency and does not affect functional compatibility. Switching speed improvements (0.02ms turn-on, 0.05ms turn-off) provide performance enhancement without compromising backward compatibility.

Parameter Comparison

Engineering Selection Recommendations

The Grayhill Inc. 70-ODC15 is the direct functional equivalent for the obsolete Sensata-Crydom 6351. Selection of the 70-ODC15 is supported by:

• Active product status ensuring long-term availability and supply chain continuity
• Identical electrical ratings for output current (4.6A) and voltage range (3 ~ 60VDC)
• Matching input supply voltage (15VDC) and mechanical interface (hold-down screw)
• Improved switching performance characteristics
• Equivalent ECCN and HTSUS classifications

The 70-ODC15 is available in bulk packaging with 863 units in stock.

Frequently Asked Questions (FAQ)

Q: Can the Grayhill 70-ODC15 directly replace the Sensata-Crydom 6351 in existing applications?

A: Yes. Both modules share identical output current (4.6A), output voltage range (3 ~ 60VDC), input supply voltage (15VDC), and mechanical mounting interface (hold-down screw). The 70-ODC15 provides equivalent or superior performance.

Q: What is the difference in input current consumption between these modules?

A: The 6351 draws 25 mA while the 70-ODC15 draws 9 mA. This difference reflects improved efficiency in the 70-ODC15 design and does not affect functional compatibility or output performance.

Q: Are there switching speed differences between these modules?

A: Yes. The 70-ODC15 offers faster switching: 0.02ms turn-on (versus 0.10ms) and 0.05ms turn-off (versus 0.10ms). These improvements enhance system response time without introducing compatibility issues.

Q: What packaging format is the 70-ODC15 supplied in?

A: The 70-ODC15 is supplied in bulk packaging.

Q: Why is the 6351 listed as obsolete?

A: The Sensata-Crydom 6351 has reached end-of-life status. The Grayhill 70-ODC15 represents the active equivalent for new designs and replacement applications.
