SY4S-61 Relay Socket Equivalent & Substitute Parts

Part Overview

The SY4S-61 is a 14-position through-hole relay socket manufactured by IDEC, designed for PCB mounting applications with RU4S/RY4S relay series compatibility. This component is classified as active product status with 791 units currently in stock. Substitute parts become necessary when the primary part experiences supply constraints, extended lead times, or when design requirements permit alternative mounting or termination configurations while maintaining functional compatibility with 14-position relay applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SY4S-61 is determined by the following critical parameters:

Primary Compatibility Criteria:

• Number of Positions: 14 (mandatory match)
• Type: Socket (mandatory match)
• Relay Socket Function: 14-position relay interface (mandatory match)

Secondary Compatibility Criteria:

• Mounting Type: Through Hole preferred; Chassis Mount acceptable with design modification
• Termination Style: PC Pin preferred; Solder Lug acceptable with PCB redesign
• Product Status: Active (ensures ongoing availability and support)

The substitute parts listed below satisfy the primary criteria. Variations in mounting type and termination style indicate design-level considerations rather than functional incompatibility with the 14-position relay socket requirement.

Engineering Selection Recommendations

Direct Substitutes (Identical Mounting and Termination):

PY14-02 and 3-1415043-1 are direct substitutes for the SY4S-61, both featuring 14-position through-hole sockets with PC pin termination. Both parts carry active product status. PY14-02 is manufactured by Omron Automation and Safety with ROHS3 compliance and MSL rating of 1 (Unlimited). Part 3-1415043-1 is manufactured by TE Connectivity Potter & Brumfield Relays with ROHS3 compliance and MSL rating of Not Applicable. Selection between these two depends on relay series compatibility requirements and inventory availability.

Alternative Substitute (Different Mounting Configuration):

27E006 is a 14-position relay socket manufactured by TE Connectivity Potter & Brumfield Relays with chassis mount configuration and solder lug termination. This part is suitable only when PCB design permits chassis mounting and solder lug connection methods. The part carries active product status and includes a grounding terminal feature. RoHS compliance is confirmed.

Frequently Asked Questions (FAQ)

Q: Can 27E006 replace SY4S-61 directly on the same PCB?

A: No. The 27E006 features chassis mount configuration and solder lug termination, whereas the SY4S-61 uses through-hole mounting with PC pin termination. Direct substitution requires PCB redesign to accommodate the different mounting and connection methods.

Q: Are PY14-02 and 3-1415043-1 interchangeable with SY4S-61?

A: Both parts match the SY4S-61 in mounting type (through hole), termination style (PC pin), and position count (14). Interchangeability depends on relay series compatibility. PY14-02 is specified for MY4/MY2K relay series, while 3-1415043-1 is specified for PT, PTH, and KHA relay series. Verify relay series compatibility before selection.

Q: What is the significance of packaging differences (Bulk, Tray, Box)?

A: Packaging type affects order quantities, storage, and handling but does not impact electrical or mechanical function. Bulk packaging typically accommodates smaller order quantities, while Tray and Box packaging may impose minimum order requirements. Verify packaging availability with your supplier.

Q: Do all substitute parts have the same RoHS compliance status?

A: No. PY14-02 and 3-1415043-1 are ROHS3 compliant. The 27E006 is RoHS compliant. Verify compliance requirements for your application before selection.

Q: What does MSL (Moisture Sensitivity Level) indicate?

A: MSL defines moisture sensitivity for storage and handling. PY14-02 has MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. Both 27E006 and 3-1415043-1 have MSL Not Applicable, indicating no moisture sensitivity concern. This parameter does not affect substitution eligibility.
