• Contact length - post (0.145" / 3.68mm)
• Contact shape (Square)

The substitute part 5536274-4 maintains full equivalence across all critical parameters while offering improved product status and regulatory compliance.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity AMP Connectors 5536274-4 serves as the direct active equivalent to the obsolete 536274-4. Both parts maintain identical electrical and mechanical specifications across all critical parameters including connector configuration, contact arrangement, pitch, voltage rating, and operating temperature range.

The primary distinction between these parts is product status and regulatory compliance. The 536274-4 is classified as obsolete and carries RoHS non-compliant status, while the 5536274-4 is an active product with ROHS3 compliance. Additionally, the 5536274-4 features tin post finish compared to the tin-lead finish of the original part, aligning with modern lead-free manufacturing standards.

For new designs and ongoing production applications, the 5536274-4 is the appropriate selection. The part maintains full form, fit, and function compatibility with the 536274-4 while providing access to current manufacturing support, improved regulatory alignment, and enhanced supply chain availability.

Frequently Asked Questions (FAQ)

Q: Are the 536274-4 and 5536274-4 electrically interchangeable?

A: Yes. Both parts are rated for 30VAC operation, support the same 100-position configuration with 0.050" (1.27mm) pitch, and operate across the identical temperature range of -65°C to 125°C. Electrical performance is equivalent.

Q: Are the 536274-4 and 5536274-4 mechanically interchangeable?

A: Yes. Both connectors feature identical through-hole mounting, shrouded 4-wall configuration, push-pull fastening, and mated stacking height of 10.92mm. Physical dimensions and mounting characteristics are fully compatible.

Q: What is the difference in contact finish between these parts?

A: The 536274-4 features tin-lead post finish, while the 5536274-4 features tin post finish. Both maintain gold mating contact finish at 30.0µin (0.76µm) thickness. The post finish difference reflects the transition to lead-free manufacturing standards.
