Mechanical Compatibility Parameters:

• Pin diameter acceptance range: 0.016" ~ 0.021" (0.41mm ~ 0.53mm)
• Square pin size acceptance: 0.011" x 0.018" (0.28mm x 0.46mm)
• Overall length: 0.100" (2.54mm)
• Mounting hole diameter: 0.044" (1.12mm)
• Tail type: No Tail

Electrical & Functional Parameters:

• Termination method: Solder
• Contact material: Beryllium Copper
• Operating temperature range: -55°C ~ 105°C
• Insertion force: 0.89N
• Series designation: HOLTITE

Regulatory & Supply Parameters:

Parameter Comparison

Engineering Selection Recommendations

The substitute part 322-HCS5P3-300LF is a direct functional equivalent to the obsolete 3-1437514-7 across all critical mechanical and electrical parameters. Selection of the substitute part is supported by the following engineering considerations:

Product Status: The substitute part maintains active production status, ensuring long-term supply chain availability and eliminating obsolescence risk associated with the original part number.

Regulatory Compliance: The substitute part achieves ROHS3 compliance, representing an improvement over the non-compliant status of the original part. Both parts maintain identical REACH Affected status and Moisture Sensitivity Level 1 classification.

Electrical & Mechanical Equivalence: All functional parameters remain identical, including pin diameter acceptance range, solder termination method, beryllium copper contact material, operating temperature range, and insertion force specifications.

Contact Finish Consideration: The substitute part features tin finish compared to the tin-lead finish of the original part. This change aligns with modern RoHS compliance requirements and does not compromise functional compatibility within the specified operating parameters.

Packaging: The substitute part is supplied in standard Tape & Reel packaging, facilitating automated assembly processes and inventory management.

Frequently Asked Questions (FAQ)

Q: Can the 322-HCS5P3-300LF directly replace the 3-1437514-7 in existing designs?

A: Yes. The substitute part maintains identical mechanical dimensions, pin acceptance specifications, solder termination method, and electrical operating parameters. No design modifications are required for direct substitution.

Q: What is the difference between the tin-lead finish of the original part and the tin finish of the substitute?

A: The tin finish of the substitute part complies with modern RoHS3 requirements while maintaining equivalent electrical and mechanical performance within the specified operating temperature range of -55°C to 105°C.
