HD6050 Solid State Relay SPST-NO 50A 48-660V Equivalent & Substitute Parts

Part Overview

The HD6050 is an active Solid State Relay (SSR) manufactured by Sensata Technologies, configured as a SPST-NO (1 Form A) hockey puck package. This component functions as an AC output relay with zero-cross switching capability, designed for industrial switching applications requiring 50A load current at 48-660V AC. The part is ROHS3 compliant and REACH affected. Equivalent and substitute parts are identified to support procurement flexibility, inventory management, and supply chain continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HD6050 is determined by strict equivalence across the following critical parameters:

• Circuit configuration: SPST-NO (1 Form A)
• Output type: AC with zero-cross switching
• Load current rating: 50A
• Load voltage range: 48-660V
• Mounting type: Chassis mount
• Termination: Screw terminal
• Package: Hockey puck form factor

The identified substitute parts (84134120 and 84137120N) maintain these core electrical and mechanical specifications. Variations in input voltage range (4-32VDC vs. 3-32VDC), packaging format (bulk vs. box), and regulatory compliance status do not affect functional substitutability within the specified load and control parameters.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain active product status and meet RoHS compliance requirements. The HD6050 and 84134120 are both REACH affected, while 84137120N is REACH unaffected. Selection between these parts should be based on:

• Supply chain availability and inventory levels
• Regulatory compliance requirements specific to the end application
• Input voltage tolerance requirements (HD6050 supports 3VDC minimum; substitutes support 4VDC minimum)
• Packaging format preference (bulk vs. box)

The electrical and mechanical specifications are equivalent across all three parts for the specified 50A, 48-660V AC load switching application.

Frequently Asked Questions (FAQ)

Q: Can 84134120 directly replace HD6050 in existing designs? A: Yes. Both parts share identical circuit configuration, output type, load current rating, load voltage range, mounting type, termination style, and package form factor. The input voltage range difference (4-32VDC vs. 3-32VDC) is not a functional barrier if the control circuit operates at 4VDC or higher.

Q: What is the difference between bulk and box packaging for these relays? A: Packaging format (bulk vs. box) affects order quantity and handling but does not alter electrical or mechanical performance. HD6050 is supplied in bulk; 84137120N is supplied in box format.

Q: Are there input voltage compatibility concerns when substituting? A: The HD6050 accepts input voltage from 3-32VDC, while both substitute parts accept 4-32VDC. If the control circuit operates at 3VDC, only the HD6050 is suitable. For control circuits operating at 4VDC or higher, all three parts are compatible.

Q: Does REACH compliance status affect substitutability? A: REACH compliance status reflects regulatory obligations in specific markets but does not affect the functional equivalence of the parts. Selection should align with the regulatory requirements of the end application and target market.

Q: Are the hockey puck packages mechanally interchangeable? A: Yes. All three parts use identical hockey puck form factor with screw terminal connections and chassis mount configuration, ensuring mechanical interchangeability in the same mounting footprint.
