Sensata-Crydom D1210 Solid State Relay SPST-NO 10A 24-140V Equivalent & Substitute Parts

Part Overview

The Sensata-Crydom D1210 is an active SPST-NO (Single Pole Single Throw - Normally Open) solid state relay in a hockey puck form factor, rated for 10A load current with input voltage range of 3-32VDC and output voltage range of 24-140V. This component is designed for AC load switching with zero-cross detection capability and chassis mount installation. The part is ROHS3 compliant and REACH affected, making it suitable for industrial control and switching applications where solid state relay technology is required.

Equivalent and substitute parts are necessary when the original D1210 is unavailable, when higher voltage ratings are required, or when alternative manufacturer sourcing is needed while maintaining functional compatibility within the specified electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the D1210 is determined by the following critical parameters: circuit type (SPST-NO), output type (AC with zero-cross), mounting type (chassis mount), termination style (screw terminal), and package form factor (hockey puck). All substitute parts must maintain these core electrical and mechanical characteristics.

The substitute parts are grouped into two categories based on load voltage capability:

Category 1 - Extended Voltage Range (24-280V): Parts 84134000, 84137000N, and ASR-SI240D10Z-LR provide higher maximum load voltage ratings (280V) compared to the D1210 (140V). These parts are direct substitutes for applications requiring higher voltage switching capability while maintaining the 10A load current rating.

Category 2 - Higher Current Rating (25A): Part SSR-240D25 provides a 25A load current rating with extended voltage range (24-280V), suitable for applications requiring higher current capacity than the D1210's 10A rating.

All substitute parts maintain the same input voltage range (3-32VDC minimum), chassis mount configuration, screw terminal termination, and hockey puck package form factor as the original D1210.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent (Same Electrical Ratings): Part 84134000 from Sensata-Crydom is the primary direct equivalent, offering identical input voltage range, load current rating, and circuit configuration with extended load voltage capability (280V vs. 140V). Both parts are ROHS3 compliant and REACH affected, ensuring regulatory alignment.

Cross-Manufacturer Equivalent (Extended Voltage): Part 84137000N from Crouzet provides equivalent functionality with extended voltage range. The input voltage minimum is 4VDC (versus 3VDC for D1210), which may be a consideration in applications with very low input voltage requirements. This part is RoHS compliant and REACH unaffected.

Alternative Voltage Range (Higher Minimum Load Voltage): Part ASR-SI240D10Z-LR from Altran Magnetics, LLC maintains the 10A load current rating but specifies a minimum load voltage of 48V (versus 24V for D1210). This part is ROHS3 compliant and REACH unaffected, suitable for applications where the load voltage floor is 48V or higher.

Higher Current Capacity: Part SSR-240D25 from TE Connectivity Potter & Brumfield Relays provides 25A load current capacity with extended voltage range (24-280V). This part is ROHS3 compliant and REACH affected, appropriate for applications requiring higher current switching than the D1210's 10A rating.

Frequently Asked Questions (FAQ)

Q: Can I use part 84134000 as a direct replacement for D1210? A: Yes. Part 84134000 maintains identical input voltage range (3-32VDC), load current (10A), circuit type (SPST-NO), output type (AC with zero-cross), mounting configuration (chassis mount), termination style (screw terminal), and package form factor (hockey puck). The extended load voltage range (280V vs. 140V) provides additional capability without affecting compatibility in applications rated for 140V or below.

Q: What is the difference between 84137000N and 84134000? A: Both parts provide 10A load current with 24-280V load voltage range and SPST-NO circuit configuration. The primary differences are manufacturer (Crouzet vs. Sensata-Crydom), input voltage minimum (4VDC vs. 3VDC), RoHS certification level (RoHS vs. ROHS3), and REACH status (unaffected vs. affected). Part 84137000N is packaged in boxes rather than bulk.

Q: When should I use ASR-SI240D10Z-LR instead of D1210? A: Part ASR-SI240D10Z-LR is suitable when your application requires load voltages of 48V or higher. The D1210 supports load voltages starting at 24V, while ASR-SI240D10Z-LR specifies a 48V minimum. Both maintain 10A load current and identical circuit/output characteristics. ASR-SI240D10Z-LR is REACH unaffected, which may be advantageous in certain regulatory contexts.

Q: Is SSR-240D25 compatible with D1210 applications? A: Part SSR-240D25 is compatible with D1210 applications that can accommodate a 25A load current rating. The part maintains identical input voltage range (3-32VDC), circuit type (SPST-NO), output type (AC with zero-cross), mounting type (chassis mount), termination style (screw terminal), and package form factor (hockey puck). The higher current rating makes it suitable for applications requiring greater current capacity than D1210's 10A specification.

Q: Do all substitute parts use the same hockey puck package? A: Yes. All substitute parts (84134000, 84137000N, ASR-SI240D10Z-LR, and SSR-240D25) use the hockey puck form factor with chassis mount configuration and screw terminal termination, ensuring mechanical compatibility with D1210 mounting and installation requirements.

Q: What is the significance of the input voltage minimum difference (3VDC vs. 4VDC)? A: Parts D1210 and 84134000 specify a 3VDC minimum input voltage, while 84137000N and ASR-SI240D10Z-LR specify 4VDC minimum. This difference is relevant only in applications where input control voltage may drop below 4VDC. For applications with input voltages of 4VDC or higher, this parameter does not affect substitution eligibility.
