Phoenix Contact 2271073 SSR Relay SPST-NO Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 2271073 is a solid-state relay (SSR) module with SPST-NO (Single Pole Single Throw - Normally Open) configuration, rated for 100 mA load current and 24 VDC input control voltage. This component operates across a load voltage range of 8 V to 48 V and features through-hole PC pin termination in a module package format.

The 2271073 is classified as obsolete. Locating equivalent or substitute components becomes necessary when original stock is depleted or when system redesigns require active product alternatives that maintain functional compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 2271073 is determined by the following critical parameters:

• Circuit Configuration: Must be SPST-NO (1 Form A) to maintain identical switching logic
• Output Type: Must be DC to ensure compatible load switching characteristics
• Input Voltage: Must support 24 VDC control signal
• Load Voltage Range: Must encompass or exceed the 8 V ~ 48 V operating window
• Load Current: Must support minimum 100 mA rating
• Termination Compatibility: Pin configuration must allow integration into existing through-hole PCB layouts

The Phoenix Contact 2966618 qualifies as a functional substitute based on these parameters. While it differs in mounting approach (socketable versus through-hole) and series designation (OPT versus SIM-EI), it maintains electrical equivalence across all critical switching and load specifications.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 2966618 provides electrical substitution for the obsolete 2271073 across all critical switching parameters: identical SPST-NO circuit configuration, DC output type, 24 VDC input control, and 100 mA load current capacity. The substitute's load voltage range (3 V ~ 48 V) encompasses the original specification (8 V ~ 48 V), ensuring compatibility with existing load circuits.

The 2966618 carries active product status and maintains current RoHS3 compliance, supporting long-term supply chain continuity. Both components share unlimited moisture sensitivity ratings (MSL 1), indicating equivalent environmental robustness.

Physical integration requires accommodation of different mounting and termination approaches. The 2271073 uses through-hole PC pin termination, while the 2966618 employs socketable plug-in termination in a 4-SIP package format. PCB redesign or adapter solutions may be necessary depending on existing board layout constraints.

Frequently Asked Questions (FAQ)

Q: Can the 2966618 directly replace the 2271073 without PCB modification?

A: Electrical substitution is valid. Physical integration depends on board design. The 2271073 uses through-hole PC pins; the 2966618 uses socketable plug-in termination. Direct socket replacement is not possible without PCB rework or mechanical adaptation.

Q: Does the 2966618 support the same load voltage range?

A: The 2966618 supports 3 V ~ 48 V, which exceeds the 2271073 specification of 8 V ~ 48 V. The substitute is compatible with all loads within the original voltage window.

Q: Are both components RoHS compliant?

A: Yes. The 2271073 is RoHS Compliant; the 2966618 is ROHS3 Compliant. Both meet current environmental standards.

Q: What is the primary advantage of selecting the 2966618?

A: The 2966618 is an active product with current manufacturing support, addressing the obsolescence status of the 2271073. Electrical performance across switching and load specifications remains equivalent.

Q: Are there differences in control signal requirements?

A: Both components require 24 VDC input control voltage. No differences exist in control signal specifications.

Q: How do the package formats differ?

A: The 2271073 is a module with through-hole PC pin termination. The 2966618 is a 4-SIP package with socketable plug-in termination, requiring different board-level integration approaches.
