Key Parameters

Substitute Part Grouping Explanation

Substitution of the S523-46 is based on the following critical parameters that define functional and mechanical compatibility:

Primary Substitution Criteria:

• Quick Connect tab connector type with solder termination
• Male gender configuration
• Non-insulated design
• Through hole, right-angle mounting
• Brass contact material with tin finish
• Tab width tolerance within 0.248" to 0.250" range (6.30mm to 6.35mm)
• Tab thickness within 0.031" to 0.032" range (0.79mm to 0.81mm)

The TE Connectivity AMP Connectors 63952-1 meets these criteria as an active product with equivalent electrical and mechanical specifications, differing only in terminal type classification (Standard vs. Angled) while maintaining functional compatibility through identical tab dimensions and contact properties.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity AMP Connectors 63952-1 is the designated substitute for the obsolete Harwin S523-46. Selection is based on:

• Product Status Alignment: The 63952-1 maintains active production status, ensuring long-term availability and supply chain continuity.
• Compliance Equivalence: Both parts maintain MSL 1 rating and RoHS compliance, meeting environmental and reliability standards.
• Dimensional Compatibility: Tab width and thickness specifications fall within acceptable tolerance ranges for mechanical and electrical interface compatibility.
• Contact Properties: Identical brass construction with tin finish ensures equivalent electrical performance and corrosion resistance.
• Packaging Availability: The 63952-1 is available in Cut Tape packaging, supporting standard procurement workflows.

Frequently Asked Questions (FAQ)

Q: What is the primary reason for substituting the S523-46? A: The S523-46 is classified as obsolete. The 63952-1 provides an active, equivalent alternative with identical functional specifications.

Q: Are the tab dimensions of the 63952-1 compatible with the S523-46 receptacles? A: Yes. The tab width difference of 0.002" (0.05mm) and thickness difference of 0.001" (0.02mm) fall within standard connector tolerance ranges for reliable mating.

Q: Do both parts meet the same environmental and compliance standards? A: Both parts maintain MSL 1 rating and RoHS compliance. The 63952-1 carries EAR99 ECCN classification, while the S523-46 is marked obsolete.

Q: What is the difference between "Angled - 90°" and "Standard" terminal type classifications? A: Both configurations support right-angle through-hole mounting. The classification difference does not affect mechanical or electrical compatibility in this application.

Q: Is the 63952-1 available in the same packaging as the S523-46? A: The 63952-1 is supplied in Cut Tape (CT) packaging. Original S523-46 packaging information is not specified in available documentation.

Q: Can the 63952-1 be used in new designs replacing the S523-46? A: Yes. The 63952-1 is recommended for both replacement and new design applications requiring 0.250" quick connect male solder tab connectors with non-insulated, right-angle configuration.
