The substitute part 3K160103 meets all mandatory compatibility criteria while offering enhanced operational specifications.

Parameter Comparison

Engineering Selection Recommendations

The 3K160103 serves as a direct functional substitute for the obsolete 4K160103. Both components share identical electrical ratings, matrix configuration, and physical mounting specifications, ensuring pin-for-pin and form-factor compatibility.

The 3K160103 is currently in active production status, providing supply chain continuity for applications previously using the 4K160103. The substitute part maintains ROHS3 compliance and CE approval, meeting regulatory requirements equivalent to the original component.

The 3K160103 offers extended operational specifications including a wider operating temperature range (-10°C to 85°C versus 0°C to 70°C) and increased operational life (2,000,000 cycles versus 1,000,000 cycles). The addition of IP54 ingress protection in the substitute part provides enhanced environmental resistance without affecting core electrical or mechanical compatibility.

Frequently Asked Questions (FAQ)

Q: Can the 3K160103 replace the 4K160103 in existing applications?

A: Yes. Both components feature identical contact ratings (0.05A @ 24VDC), 16-key 4×4 matrix configuration, conductive rubber switch technology, and panel mount specifications with 83.00mm² square cutout dimensions. Electrical and mechanical compatibility is confirmed.

Q: What are the key differences between these parts?

A: The 3K160103 provides an extended operating temperature range (-10°C to 85°C compared to 0°C to 70°C), doubled operational life (2,000,000 cycles versus 1,000,000 cycles), and IP54 ingress protection. The 4K160103 is obsolete while the 3K160103 is in active production.

Q: Are there packaging differences between the main part and substitute?

A: The 4K160103 is specified with dash packaging, while the 3K160103 is supplied in bulk packaging. Both use identical pin header termination and panel mount interfaces.

Q: Do both parts meet the same regulatory standards?

A: Yes. Both the 4K160103 and 3K160103 are ROHS3 compliant and CE approved. REACH status is unaffected for both components, and both carry the same ECCN (EAR99) and HTSUS (8537.10.9170) classifications.

Q: Which part should be selected for new designs?

A: The 3K160103 is the appropriate choice for new designs due to its active production status, extended operational specifications, and enhanced environmental protection rating.
