Amphenol ICC 89847-334 Rectangular Connector - Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 89847-334 is a 68-position receptacle connector from the Dubox™ series, designed for board-to-board applications with 0.100" (2.54mm) pitch spacing. This connector features gold-plated mating contacts, through-hole solder termination, and push-pull fastening. The part is currently classified as obsolete, making identification of compatible substitute components essential for ongoing system support and procurement planning.

Substitute Part Grouping Explanation

Substitution of the Amphenol ICC 89847-334 is determined by strict equivalence across all electrical and mechanical parameters. The primary substitute identified is the 89847-334LF, which maintains identical specifications across all critical dimensions and electrical characteristics:

Key Parameters for Substitution Equivalence:

Connector type, position count, and pitch spacing (0.100" / 2.54mm)
Row configuration and spacing
Through-hole mounting and solder termination
Push-pull fastening mechanism
Gold mating contact finish with identical thickness specification
Tin post finish with identical thickness specification
Insulation material, color, and height
Contact geometry and material composition
UL94 V-0 flammability rating

The 89847-334LF differs only in product status (Active vs. Obsolete) and RoHS compliance classification, with no changes to form, fit, or function.

Engineering Selection Recommendations

The 89847-334LF is the direct equivalent substitute for the obsolete 89847-334. Both parts are manufactured by Amphenol ICC within the Dubox™ series and maintain identical electrical and mechanical specifications across all critical parameters.

The primary distinction is product status: the 89847-334 is obsolete while the 89847-334LF is active in production. Additionally, the 89847-334LF carries RoHS compliance certification, whereas the original part is RoHS non-compliant. The substitute is packaged in tube format.

For applications requiring RoHS compliance or long-term component availability, the 89847-334LF is the appropriate selection. For legacy systems where RoHS compliance is not a requirement, both parts are functionally and mechanically interchangeable.

Frequently Asked Questions (FAQ)

Q: Are the 89847-334 and 89847-334LF physically interchangeable?

A: Yes. Both connectors share identical dimensions, pitch spacing (0.100" / 2.54mm), mounting configuration, and contact specifications. They are direct mechanical and electrical equivalents.

Q: What is the difference between these two part numbers?

A: The primary differences are product status (obsolete vs. active) and RoHS compliance classification. The 89847-334LF is the current production equivalent with RoHS compliance. All form, fit, and function parameters are identical.

Q: Can I use the 89847-334LF as a replacement in existing designs?

A: Yes. The 89847-334LF is a direct substitute with no design modifications required. The identical specifications ensure compatibility with existing PCB layouts and mating connectors.

Q: What packaging is available for the substitute part?

A: The 89847-334LF is supplied in tube packaging, whereas the original part packaging specification was not provided.

Q: Does the RoHS compliance difference affect compatibility?

A: No. RoHS compliance is a material composition and manufacturing process specification. It does not affect the electrical or mechanical performance of the connector in applications where RoHS compliance is not mandated.

Q: Are there any applications where one part should be preferred over the other?

A: The 89847-334LF should be selected for new designs and applications requiring RoHS compliance. For legacy system support where the original part is specified, either part is functionally equivalent.
