Sensata-Crydom 6201A AC Input Module 120V Equivalent & Substitute Parts

Part Overview

The Sensata-Crydom 6201A is an AC input module designed for 120VAC supply applications with 5VDC output capability. This module converts AC input signals to standardized DC output levels suitable for industrial control and automation systems. The 6201A is classified as obsolete, making identification of active equivalent parts essential for system maintenance, redesign, and procurement planning. Direct substitutes from active product lines ensure continued availability and support for legacy system upgrades.

Engineering Selection Recommendations

Primary Substitute: IAC5 (Sensata Technologies)

The IAC5 represents the direct successor within the Sensata product family. This part maintains identical electrical specifications across all critical parameters: 120VAC input, 5VDC output, 6mA input current, and 16mA output current with matching 20ms switching times. The IAC5 carries active product status with RoHS compliance certification, ensuring long-term availability and regulatory alignment. Packaging is supplied in tray format.

Secondary Substitute: IAC-5 (TE Connectivity Potter & Brumfield Relays)

The IAC-5 provides functional equivalence with minor parameter variations. Output current capability increases to 18mA, exceeding the 6201A specification and providing additional design margin. Turn-off time extends to 30ms compared to the 6201A baseline of 20ms. This part is actively manufactured with ROHS3 compliance and REACH affected status. Packaging is supplied in bulk format. The IAC-5 is suitable for applications where the increased output current and extended turn-off time do not conflict with system timing requirements.

Frequently Asked Questions (FAQ)

Q: Can the IAC5 directly replace the 6201A without circuit modification?

A: Yes. The IAC5 maintains identical electrical specifications for input voltage, output voltage, input current, output current, and switching times. Physical form factor and mounting features are equivalent. Direct substitution is supported.

Q: What is the difference between IAC5 and IAC-5 substitutes?

A: Both parts meet the core 120VAC input and 5VDC output requirements. The IAC-5 provides 18mA output current versus 16mA on the IAC5, and extends turn-off time to 30ms versus 20ms. These differences represent performance enhancements rather than incompatibilities. Selection depends on whether the application can accommodate the extended turn-off timing.

Q: Are there packaging differences between substitute options?

A: Yes. The IAC5 is supplied in tray packaging, while the IAC-5 is supplied in bulk packaging. Procurement and handling procedures may differ accordingly.

Q: What compliance certifications apply to each substitute?

A: The IAC5 carries RoHS compliance certification. The IAC-5 carries ROHS3 compliance certification and is subject to REACH regulations. Both parts meet the ECCN EAR99 and HTSUS 8536.49.0055 classifications of the original 6201A.

Q: Why is the 6201A listed as obsolete?

A: Obsolete status indicates the part is no longer manufactured by Sensata-Crydom. The IAC5 and IAC-5 represent active production alternatives that fulfill the same functional role in current system designs and legacy system support.
