Omron PTF08A-E Relay Socket 8 Position DIN Rail – Equivalent & Substitute Parts

Part Overview

The Omron PTF08A-E is an 8-position DIN rail relay socket designed for use with Omron LY Series relays (SPDT/DPDT configurations). This component provides screw terminal connectivity for relay mounting on standard DIN rail installations. The PTF08A-E is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing system maintenance and new design implementations where LY Series relay compatibility is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PTF08A-E is determined by the following critical parameters:

• Number of Positions: Must be 8
• Mounting Type: Must be DIN Rail
• Termination Style: Must be Screw Terminal
• Type: Must be Socket
• Relay Series Compatibility: Must support LY Series relays or equivalent relay families

Two substitute parts meet these criteria:

1. PTFZ08E (Omron Automation and Safety) – Manufacturer-recommended substitute with active product status and enhanced LY1/LY2 Series compatibility
2. 27E895 (TE Connectivity Potter & Brumfield Relays) – Similar substitute from alternative manufacturer, compatible with K10 Series relays

Both substitutes maintain identical mechanical and electrical specifications for the core socket function while offering improved availability and active product support compared to the obsolete PTF08A-E.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: PTFZ08E

The PTFZ08E is the manufacturer-recommended substitute for the obsolete PTF08A-E. Both are Omron products with identical mechanical and electrical socket specifications. The PTFZ08E carries active product status with ROHS3 compliance and is specifically rated for LY1 and LY2 Series relay compatibility. This substitute provides direct functional equivalence with improved long-term availability and support.

Alternative Substitute: 27E895

The 27E895 from TE Connectivity Potter & Brumfield Relays meets all critical substitution parameters: 8-position DIN rail socket with screw terminal configuration. This part is rated for K10 Series relay compatibility and maintains active product status with ROHS3 compliance. Selection of this alternative is appropriate when TE Connectivity supply chain or packaging requirements (Tray format) are preferred over Omron sourcing.

Both substitutes are suitable for direct replacement in applications requiring 8-position DIN rail relay sockets with screw terminal connectivity. Selection between PTFZ08E and 27E895 should be based on relay series compatibility requirements and supply chain preferences.

Frequently Asked Questions (FAQ)

Q: Can the PTFZ08E directly replace the PTF08A-E in existing installations?

A: Yes. Both parts are 8-position DIN rail sockets with screw terminal configuration. The PTFZ08E is the manufacturer-recommended substitute and maintains full mechanical and electrical compatibility with LY Series relays.

Q: What is the difference between PTFZ08E and 27E895?

A: Both are 8-position DIN rail relay sockets with screw terminals. The primary difference is manufacturer: PTFZ08E is Omron (recommended for LY1/LY2 Series relays), while 27E895 is TE Connectivity (rated for K10 Series relays). Packaging differs (Bulk vs. Tray). Electrical and mechanical socket specifications are equivalent.

Q: Why is the PTF08A-E obsolete?

A: The PTF08A-E has been discontinued by Omron. The PTFZ08E represents the active product line replacement with identical functionality and improved compliance certifications.

Q: Are there any compliance differences between the three parts?

A: All three parts are EAR99 classified. The PTF08A-E is RoHS Compliant. Both PTFZ08E and 27E895 are ROHS3 Compliant, representing enhanced environmental compliance standards. All three carry EAR99 export classification.

Q: Which substitute should I select for new designs?

A: For new designs using Omron LY Series relays, specify PTFZ08E. For designs using TE Connectivity K10 Series relays, specify 27E895. Both are active products with full manufacturer support.

Q: Does packaging format affect socket performance?

A: No. Packaging format (Bulk for PTFZ08E, Tray for 27E895) affects logistics and handling only. Socket electrical and mechanical performance is identical regardless of packaging.
