PSD2410 Solid State Relay - Equivalent & Substitute Parts

Part Overview

The PSD2410 is a solid state relay (SSR) manufactured by Sensata-Crydom, classified as a SPST-NO (1 Form A) hockey puck configuration. This component is rated for 10A load current with AC output and zero-cross switching capability. The part is currently obsolete, making identification of functionally equivalent alternatives necessary for system maintenance and component sourcing.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PSD2410 is determined by the following critical parameters:

• Circuit configuration: SPST-NO (1 Form A)
• Output type: AC with zero-cross switching
• Load current rating: 10 A minimum
• Mounting type: Chassis Mount
• Termination style: Screw Terminal
• Package form factor: Hockey Puck
• Input voltage range: 3 ~ 32VDC or compatible subset
• Load voltage range: Must accommodate the application's operating voltage

Two substitute parts meet these criteria with varying load voltage ranges and compliance profiles.

Parameter Comparison

Engineering Selection Recommendations

SSRT-240D10 (TE Connectivity Potter & Brumfield Relays)

This part provides direct functional equivalence with identical input voltage range (3 ~ 32VDC) and load current (10 A). The load voltage range of 24 V ~ 280 V encompasses the PSD2410's 90 V ~ 280 V specification. However, this part carries RoHS non-compliant status, which may conflict with system-level compliance requirements. Selection is appropriate for applications without RoHS mandates.

ASR-SI240D10ZW-L (Altran Magnetics, LLC)

This part meets all functional requirements with ROHS3 compliance, making it suitable for applications with RoHS3 regulatory requirements. The load voltage range of 48 V ~ 280 V covers the PSD2410's operating range above 48 V. Input voltage range is 4 ~ 32VDC, which is compatible with the PSD2410's 3 ~ 32VDC specification for applications operating at 4VDC or higher. Selection is appropriate for RoHS3-compliant system designs.

Frequently Asked Questions (FAQ)

Q: Can SSRT-240D10 replace PSD2410 in all applications?

A: SSRT-240D10 provides functional equivalence for circuit operation. The lower load voltage minimum (24 V vs. 90 V) does not restrict applications operating within the PSD2410's 90 V ~ 280 V range. RoHS compliance status must be evaluated against system requirements.

Q: What is the load voltage difference between the substitutes?

A: PSD2410 operates from 90 V ~ 280 V. SSRT-240D10 operates from 24 V ~ 280 V, providing broader low-voltage capability. ASR-SI240D10ZW-L operates from 48 V ~ 280 V. For applications requiring operation below 48 V, only SSRT-240D10 is suitable.

Q: Are all three parts mechanically interchangeable?

A: Yes. All three parts share identical mounting type (Chassis Mount), termination style (Screw Terminal), and package form factor (Hockey Puck), enabling direct mechanical substitution.

Q: Which substitute is recommended for new designs?

A: Selection depends on regulatory requirements. ASR-SI240D10ZW-L is recommended for systems requiring ROHS3 compliance. SSRT-240D10 is recommended where RoHS compliance is not mandated and load voltage operation below 48 V is required.

Q: What is the input voltage compatibility range across all parts?

A: PSD2410 and SSRT-240D10 both accept 3 ~ 32VDC input. ASR-SI240D10ZW-L accepts 4 ~ 32VDC input. For applications operating at 3VDC input, only PSD2410 or SSRT-240D10 are suitable.
