Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 85834-136 is determined by strict equivalence across the following critical parameters:

• Connector Type & Configuration: Header, male pins with identical 240-position, 5-row arrangement
• Pitch & Spacing: 0.079" (2.00mm) pitch maintained across all rows
• Mounting & Termination: Through-hole mounting with press-fit termination
• Electrical Performance: 1A current rating per contact
• Environmental Specifications: Operating temperature range -55°C to 125°C, UL94 V-0 flammability rating
• Contact Metallurgy: Gold plating at 30.0µin (0.76µm) thickness

The 85834-136LF qualifies as a direct substitute based on full parameter alignment within these criteria.

Parameter Comparison

Engineering Selection Recommendations

The 85834-136LF is the direct functional equivalent of the 85834-136. Selection between these parts should be based on the following criteria:

For New Designs and Ongoing Production: The 85834-136LF is the appropriate choice. This part maintains full electrical and mechanical compatibility while offering active product status and RoHS compliance. The transition to the 85834-136LF aligns with current regulatory requirements and ensures long-term supply chain availability.

For Legacy System Support: The 85834-136 remains functionally equivalent for applications where RoHS compliance is not mandated. However, the obsolete status of the 85834-136 necessitates migration planning to the 85834-136LF for sustained component availability.

Compliance Considerations: The 85834-136LF carries RoHS compliance and REACH-affected status, making it suitable for applications subject to environmental regulations. The original 85834-136 is RoHS non-compliant and REACH-unaffected, reflecting its legacy classification.

Frequently Asked Questions (FAQ)

Q: Can the 85834-136LF be used as a direct replacement for the 85834-136 in existing assemblies?

A: Yes. The 85834-136LF maintains identical electrical performance, mechanical dimensions, pitch, row configuration, and contact specifications. No circuit redesign or PCB modification is required for substitution.

Q: What is the primary difference between these two parts?

A: The 85834-136LF is the active production equivalent with RoHS compliance and REACH-affected status. The 85834-136 is obsolete and RoHS non-compliant. Both parts are functionally and mechanically identical.

Q: Are there packaging differences between the 85834-136 and 85834-136LF?

A: The 85834-136LF is supplied in tube packaging. The original 85834-136 packaging specification is not provided in the technical data.

Q: Does the 85834-136LF support the same operating temperature range?

A: Yes. Both parts operate across -55°C to 125°C with identical current ratings and contact metallurgy.

Q: Which part should be specified for new designs?

A: The 85834-136LF should be specified for all new designs. This part offers active product status, regulatory compliance, and assured long-term availability.
