S102S01F Solid State Relay - Equivalent & Substitute Parts

Part Overview

The S102S01F is a solid state relay (SSR) manufactured by Sharp Microelectronics, configured as a SPST-NO (Single Pole Single Throw - Normally Open) device with 1 Form A circuit topology. This component is designed for AC load switching applications with an 8A load current capacity at 80-120V output voltage range and 1.2VDC input control voltage. The product is currently classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing system maintenance and new design implementations where legacy component specifications must be maintained.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the S102S01F is determined by the following critical parameters:

Primary Compatibility Criteria:

• Circuit topology: SPST-NO (1 Form A) configuration
• Input control voltage: 1.2VDC
• Mounting type: Through Hole with PC Pin termination
• Moisture sensitivity level: MSL 1 (Unlimited)

Load Specification Considerations: The S102S01F operates with an 8A load current at 80-120V AC output. Substitute components must accommodate these electrical specifications within their rated parameters. The CPC1909J is identified as a functionally equivalent alternative, though with modified load current and voltage specifications that require engineering evaluation for specific application contexts.

Parameter Comparison

Engineering Selection Recommendations

The CPC1909J represents an active product alternative to the obsolete S102S01F. Both components share identical input control voltage (1.2VDC), circuit topology (SPST-NO 1 Form A), and moisture sensitivity classification (MSL 1). Both maintain through-hole mounting with PC pin termination.

Key differences in electrical specifications exist: the CPC1909J operates at reduced maximum load voltage (0-60V versus 80-120V) and reduced load current (6.5A versus 8A). The CPC1909J provides expanded output type capability (AC and DC versus AC only) and includes specified on-state resistance of 100 mOhms maximum.

The CPC1909J carries RoHS3 compliance and REACH unaffected status, providing regulatory alignment for modern applications. Package form factor differs (ISOPLUS264™ versus 4-SIP), requiring PCB layout verification for mechanical compatibility.

Selection of the CPC1909J as a substitute is appropriate for applications where the reduced load specifications (6.5A at 0-60V) satisfy system requirements. Applications requiring the full 8A capacity at 80-120V load voltage must evaluate alternative components outside this substitution group.

Frequently Asked Questions (FAQ)

Q: Can the CPC1909J directly replace the S102S01F in existing designs?

A: Direct replacement requires verification that application load specifications do not exceed CPC1909J ratings. The CPC1909J supports maximum 6.5A at 0-60V, compared to S102S01F specifications of 8A at 80-120V. PCB layout modification may be necessary due to package form factor differences (ISOPLUS264™ versus 4-SIP).

Q: What is the significance of the different package types (4-SIP versus ISOPLUS264™)?

A: Package form factor affects physical footprint and pin spacing on the PCB. While both use through-hole PC pin termination, the 4-SIP and ISOPLUS264™ packages have different dimensional specifications. PCB redesign or adapter solutions may be required for mechanical compatibility.

Q: Are there compliance differences between these components?

A: The CPC1909J is RoHS3 compliant and REACH unaffected. The S102S01F product status documentation does not specify these certifications. Both components carry identical ECCN (EAR99) and HTSUS (8536.41.0030) classifications and MSL 1 moisture sensitivity rating.

Q: What does the expanded output type (AC, DC) on the CPC1909J mean for substitution?

A: The CPC1909J supports both AC and DC load switching, providing broader application flexibility than the S102S01F (AC only). This capability difference does not prevent substitution in AC-only applications but enables use in DC switching scenarios where the S102S01F cannot be applied.

Q: How do the on-state resistance specifications affect performance?

A: The CPC1909J specifies 100 mOhms maximum on-state resistance. This parameter defines voltage drop across the relay during conduction. The S102S01F on-state resistance is not provided in available specifications. Lower on-state resistance reduces heat generation and power dissipation during operation.
