84115501 AC Input Module 120V Equivalent & Substitute Parts

Part Overview

The Sensata-Crydom 84115501 is an AC Input Module designed for 120VAC supply applications with 4.5–30VDC output capability. This component is classified as obsolete, making identification of active equivalent parts essential for system maintenance and new designs. The module features DIN Rail Mount configuration, status LED indication, and RoHS compliance. Substitute parts must maintain functional compatibility across input voltage, output voltage range, current ratings, and switching characteristics.

Substitute Part Grouping Explanation

Substitution eligibility for the 84115501 is determined by the following critical parameters:

• Input Voltage: Must accept 120VAC supply
• Output Voltage Range: Must support the required DC output voltage(s) for the application
• Output Current Capacity: Must meet or exceed the 32mA output current requirement
• Switching Times: Turn-on and turn-off times must be compatible with system timing requirements
• Form Factor: DIN Rail Mount configuration must be maintained
• Compliance: RoHS and regulatory certifications must be verified

The substitute parts DR-IAC5 and DRIAC24 are manufacturer-recommended alternatives from the active DR series. Both maintain 120VAC input compatibility and DIN Rail Mount configuration. However, each substitute provides a fixed output voltage (5VDC or 24VDC respectively) rather than the variable 4.5–30VDC range of the original part. Selection depends on the specific DC output voltage required by the application.

Parameter Comparison

Engineering Selection Recommendations

For 5VDC Output Applications: DR-IAC5 is the appropriate substitute. This part is active, ROHS3 compliant, and maintains the 120VAC input specification. Output current capacity is 28mA, which is within 4mA of the original 32mA rating. Turn-off time increases from 20ms to 30ms; this difference must be evaluated against system timing requirements.

For 24VDC Output Applications: DRIAC24 is the appropriate substitute. This part is active, ROHS3 compliant, and maintains the 120VAC input specification. Output current capacity is 28mA, matching the DR-IAC5 specification. Turn-off time is 30ms, consistent with the DR-IAC5 variant.

For Variable Output Voltage (4.5–30VDC) Applications: No direct substitute exists within the provided part list. The original 84115501 provides a variable output voltage range; both DR-IAC5 and DRIAC24 provide fixed output voltages. Applications requiring variable output voltage capability must either source the original 84115501 from remaining inventory or evaluate alternative product families.

Both substitute parts reduce input current consumption from 14mA to 5mA, which may provide system-level benefits. All substitute parts maintain DIN Rail Mount form factor and status LED functionality.

Frequently Asked Questions (FAQ)

Q: Can DR-IAC5 or DRIAC24 replace 84115501 in any application?

A: Substitution is possible only if the application's DC output voltage requirement matches the fixed output of the substitute part. DR-IAC5 provides 5VDC; DRIAC24 provides 24VDC. The original 84115501 supports variable output from 4.5–30VDC. If the application requires a voltage outside the substitute's fixed output, substitution is not possible.

Q: What is the impact of the increased turn-off time in the substitute parts?

A: Both DR-IAC5 and DRIAC24 have a turn-off time of 30ms compared to the original 20ms. This 10ms increase must be evaluated against system timing constraints. If the application has strict turn-off timing requirements, this difference may affect system performance.

Q: Are the substitute parts physically compatible with the original mounting?

A: Yes. Both DR-IAC5 and DRIAC24 maintain DIN Rail Mount configuration, matching the original 84115501 form factor.

Q: What is the difference in input current between the original and substitute parts?

A: The original 84115501 draws 14mA input current. Both substitute parts (DR-IAC5 and DRIAC24) draw 5mA input current. This 9mA reduction may provide benefits in power supply sizing and thermal management.

Q: Are the substitute parts RoHS compliant?

A: Yes. Both DR-IAC5 and DRIAC24 are ROHS3 compliant, meeting current regulatory requirements. The original 84115501 is RoHS compliant but does not specify ROHS3 status.

Q: What is the output current capacity difference?

A: The original 84115501 provides 32mA output current. Both substitute parts provide 28mA output current. This 4mA reduction must be verified against the application's load requirements.
