Parameter Comparison

Engineering Selection Recommendations

The 7102-05-1011 provides a functionally equivalent substitute for the 7102-05-1111 with the advantage of active product status. Both components demonstrate identical electrical performance and thermal characteristics within the specified operating range of -20°C to 85°C.

The substitute component maintains RoHS compliance at an elevated revision level (ROHS3) compared to the original part (RoHS Compliant), providing enhanced compliance assurance. Both components carry REACH Unaffected status, confirming compatibility with current regulatory frameworks.

Selection of the 7102-05-1011 eliminates obsolescence risk while maintaining full design continuity, as all critical electrical and mechanical parameters remain unchanged. The bulk packaging of the substitute part affects procurement quantity considerations but does not impact component performance or compatibility.

Frequently Asked Questions (FAQ)

Q: Can the 7102-05-1011 be used as a direct replacement for the 7102-05-1111?

A: Yes. The 7102-05-1011 is electrically and mechanically equivalent. All specified coil voltages, contact ratings, switching characteristics, and operating parameters are identical. Through-hole mounting and PC pin termination remain unchanged, enabling direct substitution in existing circuit board designs.

Q: What is the primary reason to substitute the 7102-05-1111?
