CMD48110 Solid State Relay SPST-NO 110A 48-530V

Part Overview

The CMD48110 is an active Sensata-Crydom solid state relay (SSR) featuring SPST-NO (1 Form A) configuration in a hockey puck package. This chassis-mount component handles 110A load current across 48V to 530V AC output range with zero-cross switching capability. The part operates from 4-32VDC input control voltage and uses screw terminal connections. With 689 units in current inventory and RoHS compliance certification, this relay serves industrial switching applications requiring reliable AC load control without mechanical contacts.

Substitute parts become necessary when load current requirements exceed 110A, when higher output voltage ratings are required beyond 530V, or when alternative manufacturer sourcing is preferred for supply chain optimization.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CMD48110 is determined by three critical parameters: circuit configuration (SPST-NO), output switching type (AC with zero-cross), and package form factor (hockey puck chassis mount with screw terminals). Load current and voltage ratings establish the substitution hierarchy.

The CMD48110 accepts substitutes rated for equal or greater load current (minimum 110A) and equal or greater maximum output voltage (minimum 530V). Both substitute parts listed—CWD48125 and 84137180—meet these criteria with 125A current ratings and 660V maximum voltage ratings. Input control voltage (4-32VDC), mounting configuration, and termination style remain identical across all qualified substitutes.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts maintain active product status and meet or exceed the electrical specifications of the CMD48110. The CWD48125 (Sensata-Crydom, Series CW48) provides a direct manufacturer continuation with ROHS3 compliance and REACH affected status. The 84137180 (Sensata Technologies, Series GN) offers equivalent performance with ROHS3 compliance, REACH affected status, and higher inventory availability (9880 units versus 667 units for CWD48125).

Selection between substitutes depends on supply chain requirements and manufacturer preference. Both parts are electrically and mechanically compatible with CMD48110 applications. The CWD48125 maintains the original CMD48 series lineage, while 84137180 represents the GN series alternative from the same manufacturer group.

Frequently Asked Questions (FAQ)

Q: Can CWD48125 or 84137180 directly replace CMD48110 in existing applications?

A: Yes. Both substitutes maintain identical input voltage range (4-32VDC), circuit configuration (SPST-NO), output switching type (AC zero-cross), mounting style (chassis mount), termination method (screw terminal), and package form factor (hockey puck). The substitutes are rated for higher load current (125A versus 110A) and higher maximum output voltage (660V versus 530V), making them electrically compatible for all CMD48110 applications.

Q: What are the key differences between CWD48125 and 84137180?

A: Both parts share identical electrical ratings (125A, 48-660V output). The primary differences are manufacturer designation (Sensata-Crydom versus Sensata Technologies), series designation (CW48 versus GN), and inventory levels (667 units versus 9880 units). Both hold ROHS3 compliance and REACH affected status.

Q: Are there any mechanical compatibility concerns when substituting these parts?

A: No. All three parts use identical chassis mount configuration, screw terminal termination, and hockey puck package form factor. Physical installation and electrical connection methods remain unchanged.

Q: What compliance certifications apply to substitute parts?

A: Both CWD48125 and 84137180 are ROHS3 compliant and REACH affected. The original CMD48110 is RoHS compliant. All three parts carry EAR99 export classification.
