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

Mechanical Parameters:

• Number of positions (80)
• Number of rows (2)
• Pitch - mating (0.050" / 1.27mm)
• Row spacing - mating (0.100" / 2.54mm)
• Mounting type (Through Hole)
• Shrouding configuration (Shrouded - 4 Wall)
• Fastening type (Push-Pull)
• Contact finish - mating (Gold)
• Insulation material (Thermoplastic)

The substitute part 5149011-3 satisfies all required electrical and mechanical parameters, with the distinction that it maintains active product status and improved compliance certifications.

Frequently Asked Questions (FAQ)

Q: Are the 149011-3 and 5149011-3 mechanically interchangeable?

A: Yes. Both connectors maintain identical mechanical specifications including 80 positions, 2-row configuration, 1.27mm pitch, 2.54mm row spacing, through-hole mounting, shrouded 4-wall construction, and push-pull fastening. PCB footprints and mating interface dimensions are identical.

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

A: The 149011-3 uses Tin-Lead finish on the post termination, while the 5149011-3 uses Tin finish. Both maintain identical gold plating on the mating contact surfaces at 30.0µin thickness. The post finish change reflects lead-free manufacturing compliance.

Q: Does the RoHS compliance status affect electrical performance?

A: No. RoHS compliance addresses material composition and manufacturing processes, not electrical characteristics. Both parts maintain identical voltage rating (30VAC), operating temperature range (-65°C ~ 125°C), and current handling capacity.

Q: Can the 5149011-3 be used as a direct replacement in existing designs?

A: Yes. The 5149011-3 is a direct functional equivalent with identical electrical and mechanical specifications. No design modifications, PCB layout changes, or circuit alterations are required.

Q: What is the significance of REACH status differences?

A: The 149011-3 is REACH Affected, indicating it may contain substances of very high concern (SVHC) subject to regulatory restrictions. The 5149011-3 is REACH Unaffected, confirming compliance with chemical substance regulations. This distinction is relevant for applications in regulated markets and long-term supply chain compliance.

Q: Are there any thermal or electrical performance differences?

A: No. Both connectors maintain identical operating temperature range (-65°C ~ 125°C), voltage rating (30VAC), and current handling specifications. Thermal and electrical performance characteristics are equivalent.

Q: Why is the 149011-3 listed as obsolete?

A: Obsolete status indicates the manufacturer has discontinued active production and support. The 5149011-3 represents the current active equivalent, ensuring ongoing availability and technical support for this connector family.
