AHKA21 Relay Socket 8 Position DIN Rail - Equivalent & Substitute Parts

Part Overview

The AHKA21 is an 8-position DIN rail relay socket manufactured by Panasonic Electric Works, designed for use with AHK Series relays. This component provides screw terminal connectivity for relay mounting on standard DIN rail installations. The AHKA21 is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing system maintenance and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AHKA21 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

The PTF08A from Omron Automation and Safety meets all four critical substitution criteria. Both components provide identical functional specifications for 8-position DIN rail relay socket applications with screw terminal connectivity. The PTF08A is compatible with LY Series relays and maintains the same electrical and mechanical interface requirements as the AHKA21.

Parameter Comparison

Engineering Selection Recommendations

The PTF08A is the qualified substitute for the AHKA21 based on matching electrical and mechanical specifications. The PTF08A holds active product status with ROHS3 compliance and REACH unaffected certification, providing regulatory compliance advantages over the obsolete AHKA21. Both components share identical core functional parameters: 8-position configuration, DIN rail mounting, and screw terminal termination.

Selection of the PTF08A is appropriate for applications requiring an 8-position DIN rail relay socket with screw terminal connectivity. The active product status and compliance certifications of the PTF08A support long-term component availability and regulatory adherence.

Frequently Asked Questions (FAQ)

Q: What makes PTF08A a suitable substitute for AHKA21?

A: The PTF08A matches all critical functional parameters of the AHKA21: 8-position configuration, DIN rail mounting type, and screw terminal termination. Both components provide identical electrical and mechanical interfaces for relay socket applications.

Q: Are there compatibility concerns when substituting AHKA21 with PTF08A?

A: The PTF08A is designed for LY Series relays, while the AHKA21 is specified for AHK Series relays. Mechanical and electrical compatibility must be confirmed based on the specific relay model used in the application.

Q: What is the significance of product status in this substitution?

A: The AHKA21 is obsolete, meaning it is no longer manufactured or supported by Panasonic Electric Works. The PTF08A is active, ensuring ongoing availability and manufacturer support for future procurement and technical assistance.

Q: Does the PTF08A offer any regulatory advantages?

A: The PTF08A carries ROHS3 compliance and REACH unaffected certification. These certifications support compliance with environmental and chemical safety regulations in applicable markets.

Q: Are packaging considerations relevant to this substitution?

A: The AHKA21 packaging is listed as unspecified, while the PTF08A is supplied in bulk packaging. Packaging format does not affect functional compatibility but may influence procurement quantities and handling procedures.
