S423-46 Equivalent & Substitute Parts

Part Overview

The S423-46 is a 0.110" (2.79mm) Quick Connect Male Solder Connector manufactured by Harwin Inc. This non-insulated terminal is designed for through-hole solder applications. The part is currently obsolete, making identification of compatible substitute components essential for ongoing maintenance, repair, and new design implementations where legacy compatibility is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the S423-46 is determined by strict equivalence across the following critical parameters:

• Tab Width: 0.110" (2.79mm) — determines mating compatibility
• Terminal Type: Standard male quick connect configuration
• Termination Method: Solder attachment
• Insulation: Non-insulated construction
• Contact Material: Brass with tin finish
• Mounting: Through-hole PCB application

The substitute part 63756-1 (TE Connectivity AMP Connectors, Faston series) satisfies all primary functional requirements. Minor dimensional variations in tab thickness (0.032" vs. 0.031"), tab length (0.417" vs. 0.575"), and overall length (0.622" vs. 0.748") do not prevent functional substitution in standard quick-connect applications, as these tolerances remain within typical connector design specifications for this connector class.

Parameter Comparison

Engineering Selection Recommendations

The 63756-1 (TE Connectivity AMP Connectors, Faston series) is the qualified substitute for the obsolete S423-46. Both components maintain ROHS3 compliance and identical MSL ratings, ensuring regulatory and environmental consistency in replacement applications.

The substitute part is currently in active production with confirmed inventory availability (2200 pcs), providing supply chain continuity for legacy system support and new designs requiring 0.110" quick-connect male solder terminals.

Dimensional variations between the original and substitute are within acceptable tolerances for quick-connect terminal applications and do not compromise electrical or mechanical performance in standard through-hole PCB mounting configurations.

Frequently Asked Questions (FAQ)

Q: Can the 63756-1 be used as a direct replacement for the S423-46?

A: Yes. Both components share identical tab width (0.110"), terminal type, gender, termination method, insulation configuration, contact material, and finish. Minor dimensional differences in tab and overall length do not prevent functional substitution in standard quick-connect applications.

Q: What are the key compatibility criteria for this connector class?

A: Tab width (0.110"), male gender, solder termination, non-insulated construction, and brass tin-plated contact material are the primary determinants of compatibility. The 63756-1 matches all these specifications.

Q: Does the substitute part meet the same compliance standards?

A: Yes. Both the S423-46 and 63756-1 are ROHS3 compliant with MSL rating 1 (Unlimited), ensuring equivalent environmental and regulatory performance.

Q: What is the packaging format for the substitute part?

A: The 63756-1 is supplied in Cut Tape (CT) packaging, standard for terminal components in production environments.

Q: Why are the tab and overall lengths different between the two parts?

A: These dimensional variations reflect different design generations within the 0.110" quick-connect terminal category. Both dimensions remain functionally compatible for through-hole solder applications where the connector engages with standard female quick-connect receptacles.
