PYF14A Relay Socket - Equivalent & Substitute Parts

Part Overview

The PYF14A is a 14-position DIN rail relay socket manufactured by Omron Automation and Safety, designed for use with MY and MY2K series relays. This product is classified as obsolete, making identification of suitable substitute components essential for ongoing maintenance, repair, and system continuity in industrial automation applications.

The socket features screw terminal connections and is optimized for DIN rail mounting in control panel environments. Due to its obsolete status, equivalent parts from active manufacturers are necessary to ensure long-term component availability and supply chain reliability.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the PYF14A is determined by strict equivalence in the following critical parameters:

• Number of Positions: 14 positions (electrical interface requirement)
• Mounting Type: DIN Rail (mechanical form factor)
• Termination Style: Screw Terminal (connection method)
• Type: Socket (functional classification)

The substitute part 27E894 meets all four critical parameters, establishing functional and mechanical compatibility. Both parts are 14-position DIN rail sockets with screw terminal connections, enabling direct substitution in relay socket applications.

Parameter Comparison

Engineering Selection Recommendations

The 27E894 is the qualified substitute for the PYF14A based on the following factors:

Product Status: The PYF14A is obsolete, while the 27E894 maintains active product status with current manufacturing support and documented availability.

Compliance Certifications: Both parts meet RoHS requirements. The PYF14A is RoHS Compliant; the 27E894 is ROHS3 Compliant, representing current regulatory standards. The 27E894 is additionally REACH Unaffected, confirming compliance with European chemical regulations.

Electrical and Mechanical Equivalence: Both sockets are 14-position DIN rail devices with screw terminal connections, satisfying the core functional requirements for relay socket applications.

Supply Chain Continuity: The 27E894 is actively manufactured and stocked, providing reliable long-term availability compared to the obsolete PYF14A.

Frequently Asked Questions (FAQ)

Q: Can the 27E894 directly replace the PYF14A in existing installations?

A: Yes. Both parts are 14-position DIN rail sockets with screw terminal connections. The mechanical form factor and electrical interface are equivalent, enabling direct substitution without circuit modification.

Q: What is the significance of the product status difference?

A: The PYF14A is classified as obsolete, indicating discontinued manufacturing and limited future availability. The 27E894 is active, ensuring ongoing supply and manufacturer support for future orders and replacements.

Q: Are there compliance differences between these parts?

A: Both parts are RoHS compliant. The 27E894 carries ROHS3 Compliant status, representing the current RoHS directive version. The 27E894 is also REACH Unaffected, confirming compliance with European chemical substance regulations.

Q: Does the Moisture Sensitivity Level difference affect substitution?

A: No. The PYF14A specifies MSL 1 (Unlimited), indicating no moisture sensitivity constraints. The 27E894 lists MSL as Not Applicable, which is consistent with socket-type components that do not require moisture sensitivity classification. This difference does not impact substitution suitability.

Q: What relay series are compatible with the 27E894?

A: The 27E894 is designed for use with PT, PTH, and KHA series relays. Compatibility with the original MY and MY2K series relays should be verified through mechanical and electrical interface specifications before deployment.
