• Voltage rating (30VAC)
• Operating temperature range (-65°C ~ 125°C)

Mechanical Compatibility Parameters:

• Mounting type (Through Hole)
• Termination method (Solder)
• Fastening type (Push-Pull)
• Insulation material (Thermoplastic)
• Contact finish - mating (Gold)
• Mated stacking heights (10.92mm, 17.78mm, 18.75mm)

Regulatory & Compliance Parameters:

• Series designation (Micro-Strip)
• Moisture sensitivity level (MSL 1)

The substitute part 5536254-4 maintains full equivalence across all critical parameters while offering active product status and improved regulatory compliance.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity 5536254-4 serves as the direct active equivalent to the obsolete 536254-4. Both connectors maintain identical electrical and mechanical specifications across all critical parameters including connector type, position count, pitch, row configuration, mounting method, and operating characteristics.

The primary distinction between these parts is product status and regulatory compliance. The 536254-4 is classified as obsolete with RoHS non-compliant status, while the 5536254-4 is an active product with RoHS Compliant certification. The contact finish on the post differs slightly (tin-lead versus tin), representing a functional equivalence that does not impact electrical performance or mechanical compatibility.

For new designs and ongoing procurement, the 5536254-4 is the appropriate selection due to its active status and improved regulatory compliance posture. For legacy system maintenance where the original 536254-4 is specified, the 5536254-4 provides direct substitution without design modification or PCB rework.

Frequently Asked Questions (FAQ)

Q: Can the 5536254-4 be used as a direct replacement for the 536254-4 in existing assemblies?

A: Yes. The 5536254-4 maintains identical electrical and mechanical specifications across all critical parameters. Pin-to-pin compatibility, mating pitch, row spacing, mounting footprint, and operating characteristics are equivalent. No PCB modification or connector redesign is required.

Q: What is the difference between the tin-lead post finish on the 536254-4 and the tin post finish on the 5536254-4?

A: Both finishes provide equivalent electrical conductivity and solder joint reliability. The tin finish on the 5536254-4 represents a lead-free alternative that aligns with RoHS compliance requirements while maintaining functional performance in solder termination applications.

Q: Are the mated stacking heights identical between these two connectors?

A: Yes. Both the 536254-4 and 5536254-4 support identical mated stacking heights of 10.92mm, 17.78mm, and 18.75mm, ensuring compatibility with existing mechanical assemblies and enclosure designs.

Q: What is the significance of the RoHS compliance difference?

A: The 5536254-4 is RoHS Compliant, meeting regulatory requirements for restricted hazardous substances in electrical and electronic equipment. The 536254-4 is RoHS non-compliant. For applications subject to RoHS regulations or customer requirements, the 5536254-4 is the appropriate selection.

Q: Are both connectors rated for the same operating temperature range?

A: Yes. Both the 536254-4 and 5536254-4 operate across the identical temperature range of -65°C to 125°C, supporting equivalent thermal performance in industrial and commercial applications.

Q: What is the moisture sensitivity level for these connectors?

A: Both connectors are classified as MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. These parts do not require special moisture control during storage, handling, or assembly.

Q: Can these connectors be used interchangeably in board-to-board applications?

A: Yes. Both connectors are designed for board-to-board applications with identical push-pull fastening, through-hole solder termination, and mechanical mounting specifications. They are fully interchangeable in this application category.
