H12D4840D Solid State Relay - Equivalent & Substitute Parts

Part Overview

The H12D4840D is a solid state relay (SSR) manufactured by Sensata-Crydom, classified as SPST-NO (Single Pole Single Throw - Normally Open) with dual Form A circuits in a Hockey Puck package. This component is designed for AC load switching applications with zero-cross detection capability. The part is currently in active production status with 870 units available in inventory. Substitute parts may be required due to supply constraints, application-specific voltage requirements, or packaging preferences while maintaining equivalent electrical performance.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the H12D4840D is determined by the following critical parameters:

Primary Compatibility Criteria:

• Circuit configuration: SPST-NO (1 Form A) x 2
• Output type: AC with zero-cross detection
• Input voltage range: 4 ~ 15VDC
• Load current rating: 40 A
• Termination style: Quick Connect - 0.250" (6.3mm)
• Mounting type: Chassis Mount

Secondary Compatibility Criteria:

• Load voltage range (must encompass or match the application requirement)
• Package type (Hockey Puck or Module formats)
• RoHS compliance status

The identified substitute parts maintain identical input voltage, load current, circuit configuration, and termination specifications. Variations exist in maximum load voltage ratings and package formats, which determine suitability for specific applications.

Parameter Comparison

Engineering Selection Recommendations

84140600 (Sensata-Crydom GN2 Series): This substitute maintains identical input voltage, load current, circuit configuration, and termination specifications as the H12D4840D. The maximum load voltage rating extends to 660V, providing broader application coverage compared to the 530V maximum of the main part. Both components are RoHS Compliant and in active production. The Hockey Puck package format ensures mechanical compatibility with existing mounting infrastructure designed for the H12D4840D.

ASR-SID480D40ZL (Altran Magnetics SID Series): This substitute maintains identical input voltage, load current, circuit configuration, and termination specifications. The load voltage range is 24V to 530V, which covers the lower end of the H12D4840D specification (48V minimum) but matches the upper limit. The component is ROHS3 Compliant and in active production. The Module package format differs from the Hockey Puck configuration, requiring evaluation of mechanical fit within the target application.

Selection between substitutes depends on application-specific load voltage requirements and physical space constraints. Both alternatives maintain full electrical compatibility with the control circuit interface.

Frequently Asked Questions (FAQ)

Q: Can the 84140600 be used in place of the H12D4840D? A: Yes. Both components share identical input voltage (4~15VDC), load current (40A), circuit configuration (SPST-NO x 2), and termination style (Quick Connect 0.250"). The 84140600 supports a higher maximum load voltage (660V vs. 530V), making it suitable for applications operating within the H12D4840D's 48~530V range.

Q: What is the key difference between the 84140600 and ASR-SID480D40ZL? A: The primary differences are manufacturer (Sensata-Crydom vs. Altran Magnetics), load voltage range (48~660V vs. 24~530V), and package format (Hockey Puck vs. Module). Both maintain identical input voltage, load current, and circuit configuration.

Q: Is the ASR-SID480D40ZL compatible with applications requiring 48V minimum load voltage? A: The ASR-SID480D40ZL supports load voltages from 24V to 530V. Applications requiring a 48V minimum load voltage fall within this range; however, the lower minimum specification (24V vs. 48V) should be evaluated against application requirements.

Q: Does package format affect electrical performance? A: No. The Hockey Puck and Module package formats do not affect electrical performance. Package selection is determined by mechanical mounting requirements and available space within the target application.

Q: Are all three components RoHS compliant? A: Yes. The H12D4840D and 84140600 are RoHS Compliant. The ASR-SID480D40ZL is ROHS3 Compliant, which represents an updated compliance standard.
