Key Parameters

Substitute Part Grouping Explanation

Substitution of the Sensata-Crydom 6131 is determined by the following critical parameters:

• Input Voltage Compatibility: 24VDC supply requirement
• Output Voltage Specification: 15VDC output level
• Output Current Capacity: Minimum 14mA requirement
• Input Current Draw: 16 mA specification
• Switching Response Time: Turn-on and turn-off timing characteristics
• Physical Features: Hold down screw mounting compatibility
• Form Factor: Standard style DC input module configuration

The IDC15 series from Sensata-Crydom meets these substitution criteria while offering improved switching performance and enhanced compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The IDC15 serves as the manufacturer-recommended substitute for the 6131. Both components are classified as obsolete products from Sensata-Crydom. The IDC15 maintains electrical compatibility across all critical parameters: 24VDC input supply, 15VDC output voltage, and 16 mA input current specification.

The IDC15 provides enhanced output current capacity (16mA versus 14mA) and superior switching response times (1ms versus 5ms for both turn-on and turn-off). These improvements ensure functional compatibility while offering performance advantages in legacy system replacements.

The IDC15 carries RoHS Compliant certification, whereas the 6131 status is not specified. Both components share identical ECCN (EAR99) and HTSUS (8536.41.0030) classifications, confirming regulatory equivalence for export and tariff purposes.

Frequently Asked Questions (FAQ)

Q: Can the IDC15 directly replace the 6131 in existing installations?

A: Yes. The IDC15 maintains identical input voltage (24VDC), output voltage (15VDC), and input current (16 mA) specifications. The physical mounting feature (hold down screw) is preserved. The faster switching times (1ms versus 5ms) represent an improvement that does not compromise backward compatibility.

Q: What is the significance of the higher output current rating on the IDC15?

A: The IDC15 provides 16mA output current capacity compared to the 6131's 14mA. This 2mA increase ensures the substitute can handle the original application load with additional margin, supporting system reliability in replacement scenarios.

Q: Are there packaging differences between the 6131 and IDC15?

A: Both components are specified as standard style DC input modules with hold down screw features. No packaging incompatibilities are indicated in the provided specifications.

Q: What compliance certifications apply to these components?

A: Both the 6131 and IDC15 are classified under ECCN EAR99 and HTSUS 8536.41.0030. The IDC15 carries RoHS Compliant certification. Both components have Moisture Sensitivity Level (MSL) marked as Not Applicable.

Q: Why are both the original and substitute parts classified as obsolete?

A: Obsolete status indicates these components are no longer in active production. For applications requiring active production support, consultation with Sensata-Crydom regarding current-generation DC input module alternatives is recommended.
