HC4-SS-K Relay Socket 14 Position Panel Mount - Equivalent & Substitute Parts

Part Overview

The HC4-SS-K is a 14-position panel mount relay socket manufactured by Panasonic Electric Works, designed for use with HC4 series relays. This component is classified as obsolete, making identification of equivalent and substitute parts essential for ongoing maintenance, repair, and system support applications. The socket provides solder lug termination and includes mounting hardware for secure panel installation.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the HC4-SS-K are identified based on the following critical parameters that determine functional compatibility:

Primary Substitution Criteria:

• Number of Positions: 14 (exact match required)
• Type: Socket (exact match required)
• Termination Style: Solder Lug (exact match required)
• Mounting Type: Panel Mount (preferred) or Chassis Mount (with installation considerations)

Substitute Classification:

Direct Substitute (PY14): Omron Automation and Safety PY14 matches all primary criteria—14-position socket with panel mount configuration and solder lug termination. Designed for MY4/MY2K relay series. Product status is active with current inventory availability.

Similar Substitute (27E006): TE Connectivity Potter & Brumfield 27E006 provides 14-position socket configuration with solder lug termination but uses chassis mount instead of panel mount. Includes grounding terminal feature. Designed for PT, PTH, and KHA series relays. Product status is active.

Similar Substitute (V23105A5405A201): TE Connectivity Potter & Brumfield V23105A5405A201 is a telecom relay (not a socket) with DPDT contact form, 24VDC coil, and through-hole termination. This part represents a different product category and is included in the original substitute list but does not meet socket substitution criteria.

Parameter Comparison

Engineering Selection Recommendations

PY14 (Omron Automation and Safety) is the primary substitute for HC4-SS-K applications. This part maintains identical mechanical and electrical interface specifications: 14-position configuration, panel mount mounting, and solder lug termination. PY14 holds active product status with ROHS3 compliance and unlimited moisture sensitivity rating, providing superior long-term availability and regulatory alignment compared to the obsolete HC4-SS-K.

27E006 (TE Connectivity Potter & Brumfield) serves as an alternative when chassis mount configuration is acceptable within system design constraints. This part provides 14-position socket functionality with solder lug termination and includes a grounding terminal. Chassis mount installation requires mechanical redesign of mounting provisions. Product status is active with RoHS compliance.

V23105A5405A201 is not recommended as a substitute for HC4-SS-K socket applications. This component is a telecom relay with DPDT contact form and through-hole termination, representing a different functional category. Inclusion in the original substitute list does not indicate socket compatibility.

Frequently Asked Questions (FAQ)

Q: Can PY14 directly replace HC4-SS-K in existing applications? A: PY14 provides direct mechanical and electrical compatibility. Both parts feature 14-position configuration, panel mount mounting type, and solder lug termination. Verify relay series compatibility: HC4-SS-K is designed for HC4 relays, while PY14 is designed for MY4/MY2K relays. Confirm that MY4/MY2K relay pin configuration matches HC4 relay specifications for your application.

Q: What is the primary difference between PY14 and 27E006? A: The primary difference is mounting type. PY14 uses panel mount configuration identical to HC4-SS-K, while 27E006 uses chassis mount configuration. Both provide 14-position socket functionality with solder lug termination. Selection depends on available mounting space and mechanical design constraints in your system.

Q: Why is V23105A5405A201 listed as a substitute if it is not a socket? A: V23105A5405A201 is a telecom relay, not a relay socket. This part does not provide socket functionality and is not suitable for HC4-SS-K replacement in applications requiring a 14-position socket interface. This part appears in the original substitute list but does not meet socket substitution criteria.

Q: What compliance certifications should I verify for substitute parts? A: PY14 holds ROHS3 compliance and REACH unaffected status. 27E006 holds RoHS compliance. Both parts carry EAR99 export classification. Verify that selected substitute parts meet your system's regulatory and compliance requirements before implementation.

Q: Are there packaging considerations when selecting a substitute? A: HC4-SS-K is supplied in standard packaging. PY14 is supplied in bulk packaging, while 27E006 is supplied in tray packaging. Verify packaging format compatibility with your procurement and assembly processes. All parts maintain MSL 1 (unlimited) or not applicable ratings, indicating no special moisture handling requirements during storage or assembly.
