C230S Solid State Relay - Equivalent & Substitute Parts

Part Overview

The C230S is a solid state relay (SSR) manufactured by Coto Technology in the COTOMOS™ series. This device is a Surface Mount SPST-NO (1 Form A) relay rated for 100 mA load current across 0-400V AC/DC applications with a 4-SOP package form factor. The product is classified as obsolete, necessitating identification of equivalent substitute components for new design implementations and production continuity. Alternative models must meet or exceed the electrical and mechanical specifications required for drop-in replacement functionality.

Key Parameters

Substitute Part Grouping Explanation

The VOR1142B4 qualifies as a suitable substitute for the C230S based on the following critical substitution parameters:

Electrical Compatibility Requirements:

• Circuit Configuration: Both devices implement SPST-NO (1 Form A) topology
• Output Type: Both support AC and DC load switching
• Load Voltage Range: Both rated for 0 V ~ 400 V (identical specification)
• Input Control Voltage: VOR1142B4 (1.36 VDC) is functionally equivalent to C230S (1.37 VDC)
• Load Current: VOR1142B4 (140 mA) exceeds C230S requirement (100 mA), enabling drop-in replacement
• On-State Resistance: VOR1142B4 (27 Ohms max) remains within acceptable tolerance relative to C230S (24 Ohms max)

Mechanical and Environmental Compatibility:

• Mounting Type: Both devices are Surface Mount with Gull Wing termination
• RoHS Compliance: Both meet ROHS3 requirements
• Regulatory: Both carry REACH Unaffected and EAR99 ECCN designations

Product Status Consideration: The VOR1142B4 is classified as Active, providing long-term component availability and manufacturing support compared to the obsolete C230S.

Parameter Comparison

Engineering Selection Recommendations

The VOR1142B4 is the designated substitute for the obsolete C230S, meeting all critical electrical and mechanical compatibility criteria. Both devices meet ROHS3 compliance and carry identical REACH and ECCN regulatory designations, ensuring no additional compliance burden in design transitions.

The primary design consideration is package footprint: the VOR1142B4 employs a 4-SMD (0.300", 7.62mm) package compared to the C230S 4-SOP (0.173", 4.40mm) form factor. PCB layout modifications are required to accommodate the larger package dimensions. The enhanced load current capability (140 mA vs. 100 mA) and superior moisture sensitivity rating (MSL 1 vs. MSL 2) provide additional design margin for production applications.

Frequently Asked Questions (FAQ)

Q: Can the VOR1142B4 directly replace the C230S without circuit modifications?

A: Electrical parameters are compatible for direct functional replacement. However, the larger package footprint (4-SMD vs. 4-SOP) requires PCB layout revision. No modifications to control or load circuits are necessary if PCB space accommodates the larger package dimensions.

Q: What is the significance of the higher load current rating on the VOR1142B4?

A: The VOR1142B4 supports 140 mA versus the C230S 100 mA specification. This provides design margin for applications operating near the 100 mA limit of the original component and may extend component lifespan through reduced thermal stress at rated load conditions.

Q: Are there input voltage differences between these devices?

A: Control input voltage is nominally equivalent (1.37 VDC vs. 1.36 VDC), representing a 0.01 VDC variance. Both devices operate within standard logic-level control circuits without circuit redesign.

Q: What impact does the package size change have on thermal performance?

A: The larger 4-SMD package of the VOR1142B4 may provide marginally improved thermal characteristics compared to the compact 4-SOP form factor through increased surface area contact with the PCB and solder pad metallization.

Q: Is the VOR1142B4 suitable for long-term production applications?

A: Yes. The Active product status of the VOR1142B4 ensures sustained manufacturing support and component availability compared to the obsolete C230S. ROHS3 compliance and regulatory equivalence support continued production without lifecycle discontinuation risk.
