Substitute Part Grouping Explanation

The 70243-111LF qualifies as a direct substitute based on matching electrical and mechanical parameters. Substitution is valid when the following criteria are met:

• Connector type: Housing for Male Pins (identical)
• Position count and coaxial configuration: 6 (Coax) (identical)
• Pitch specification: 0.157" (4.00mm) (identical)
• Row configuration: 2 rows (identical)
• Connector style: Rack and Panel (identical)
• Mounting method: Through Hole (identical)
• Board guide feature: Present (identical)
• Color: Natural (identical)
• Series compatibility: Metral® (identical)

The 70243-111LF maintains full compatibility with applications designed for the 70243-111, with the additional advantage of active product status and RoHS compliance.

Parameter Comparison

Engineering Selection Recommendations

The 70243-111LF is the appropriate selection for new designs and system replacements. The main part (70243-111) is obsolete and no longer actively manufactured. The substitute part maintains complete electrical and mechanical compatibility while offering active product status and RoHS compliance certification. Both parts share identical REACH and ECCN classifications, ensuring regulatory consistency. The transition from 70243-111 to 70243-111LF presents no functional or dimensional constraints for connector integration.

Frequently Asked Questions (FAQ)

Q: Can the 70243-111LF directly replace the 70243-111 in existing assemblies?

A: Yes. The 70243-111LF maintains identical electrical and mechanical specifications, including connector type, position count, pitch, row configuration, mounting method, and board guide feature. Direct substitution is valid for all applications designed for the 70243-111.

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

A: The 70243-111 is obsolete, while the 70243-111LF is an active product. The 70243-111LF also carries RoHS compliance certification, whereas the 70243-111 is RoHS non-compliant. All other specifications remain identical.

Q: Are there packaging differences between the two parts?

A: The 70243-111 is listed with no specified packaging, while the 70243-111LF is supplied in bulk packaging. This distinction affects procurement and handling but does not impact connector functionality or compatibility.

Q: Do both parts meet the same regulatory requirements?

A: Both parts share identical REACH and ECCN classifications (REACH Unaffected, EAR99). The 70243-111LF provides additional RoHS compliance certification. Both maintain MSL 1 (Unlimited) moisture sensitivity rating.

Q: Is the Metral® series designation consistent across both parts?

A: Yes. Both the 70243-111 and 70243-111LF belong to the Amphenol ICC Metral® series, ensuring design continuity and connector ecosystem compatibility.
