SYF-41T-P0.5A Equivalent & Substitute Parts

Part Overview

The SYF-41T-P0.5A is a rectangular connector socket contact manufactured by JST Sales America Inc. This component is a tin-plated crimp socket designed for 16-20 AWG wire gauges and is part of the YL and YLN series. The part maintains Active product status with RoHS compliance and unlimited moisture sensitivity rating (MSL 1). Alternative equivalent parts are necessary when addressing supply chain constraints, series compatibility requirements, or specific connector interface specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SYF-41T-P0.5A is determined by the following critical parameters:

Primary Substitution Criteria:

• Contact type: Socket
• Wire gauge compatibility: 16-20 AWG
• Termination method: Crimp
• Contact finish: Tin
• RoHS compliance status
• MSL rating: 1 (Unlimited)

Substitute Parts Identified:

Group 1 - Rectangular Connector Sockets (Direct Category Match):

• 173631-6 (TE Connectivity AMP Connectors, Multi-Lock series)
• 175027-6 (TE Connectivity AMP Connectors, Multi-Lock series)

These parts match the primary substitution criteria as rectangular connector socket contacts with identical wire gauge, crimp termination, tin finish, and RoHS compliance.

Group 2 - Quick Connect Terminals (Alternative Interface):

• 1-160759-2 (TE Connectivity AMP Connectors, Mark I series, 0.250" tab width)
• 353250-2 (TE Connectivity AMP Connectors, Positive Lock EX-III series, 0.110" tab width)

These parts share wire gauge, crimp termination, tin finish, and RoHS compliance but differ in connector interface type (quick connect female terminals versus rectangular socket contacts). Substitution requires mechanical interface compatibility verification.

Parameter Comparison

Engineering Selection Recommendations

For Direct Rectangular Connector Socket Substitution:

Parts 173631-6 and 175027-6 are functionally equivalent rectangular connector socket contacts. Both maintain Active product status, RoHS compliance (ROHS3), and MSL 1 rating. Selection between these options depends on series compatibility requirements within the connector assembly. 173631-6 offers higher inventory availability (25,384 pcs) compared to 175027-6 (863 pcs).

For Quick Connect Terminal Substitution:

Parts 1-160759-2 and 353250-2 are non-insulated quick connect female terminals with different tab geometries. These parts share electrical specifications (wire gauge, crimp termination, tin finish, RoHS compliance) but require mechanical interface compatibility with the mating connector design. 1-160759-2 features a 0.250" tab width, while 353250-2 features a 0.110" tab width. Selection depends on the specific quick connect receptacle interface in the application.

All substitute parts maintain Active product status and equivalent environmental compliance ratings to the primary part.

Frequently Asked Questions (FAQ)

Q: Can 173631-6 or 175027-6 directly replace SYF-41T-P0.5A in an existing assembly?

A: Both parts are rectangular connector socket contacts with matching wire gauge (16-20 AWG), crimp termination, and tin finish. However, they belong to different connector series (Multi-Lock versus YL/YLN). Direct substitution requires verification that the Multi-Lock series socket is mechanically compatible with the existing YL/YLN connector housing and pin configuration.

Q: What is the difference between the rectangular connector sockets and the quick connect terminals?

A: The rectangular connector sockets (173631-6, 175027-6) are designed for use within rectangular connector housings. The quick connect terminals (1-160759-2, 353250-2) are standalone female terminals with tab interfaces for quick-disconnect applications. These represent different connector architectures and are not interchangeable without redesigning the mating interface.

Q: Are the quick connect terminals (1-160759-2 and 353250-2) interchangeable with each other?

A: Both quick connect terminals share wire gauge, termination, and finish specifications. However, they differ in tab width (0.250" versus 0.110") and overall length. Substitution between these parts requires compatibility with the specific quick-connect receptacle design in the application.

Q: Do all substitute parts meet the same RoHS compliance level?

A: The primary part SYF-41T-P0.5A is RoHS Compliant. Substitute parts 173631-6 and 175027-6 are RoHS Compliant or ROHS3 Compliant, and quick connect terminals 1-160759-2 and 353250-2 are ROHS3 Compliant. All parts meet RoHS requirements; ROHS3 represents a more recent compliance standard.

Q: What packaging formats are available for these substitute parts?

A: 173631-6, 1-160759-2, and 353250-2 are supplied in Cut Tape (CT) packaging. 175027-6 packaging format is not specified in available data. Packaging selection should align with assembly process requirements and inventory management practices.

Q: Which substitute part offers the best inventory availability?

A: 173631-6 provides the highest inventory level at 25,384 pcs in stock, followed by 353250-2 at 16,992 pcs, 1-160759-2 at 9,025 pcs, and 175027-6 at 863 pcs.
