88333-044LF Equivalent & Substitute Parts

Part Overview

The 88333-044LF is a 44-position rectangular receptacle connector manufactured by Amphenol ICC (FCI) in the Minitek® series. This board-to-board connector features a 0.079" (2.00mm) pitch, right-angle through-hole mounting, and gold-plated mating contacts. The product is currently obsolete, making identification of compatible substitute parts essential for ongoing system support and component procurement.

Substitute Part Grouping Explanation

The 4-1734531-4 (TE Connectivity AMP Connectors, AMPMODU series) qualifies as a direct substitute for the 88333-044LF based on the following critical parameters:

• Connector Type & Contact Configuration: Both are 44-position receptacle connectors with female socket contacts
• Pitch & Row Spacing: Identical 0.079" (2.00mm) mating pitch and row spacing
• Mounting & Termination: Both feature through-hole, right-angle mounting with solder termination
• Fastening Mechanism: Both use push-pull fastening
• Contact Material & Finish: Both employ phosphor bronze contacts with gold mating finish and tin post finish
• Flammability Compliance: Both meet UL94 V-0 material flammability rating
• Contact Shape: Both use square contact geometry

The substitute part maintains mechanical and electrical compatibility through these aligned specifications, enabling direct replacement in board-to-board applications.

Parameter Comparison

Engineering Selection Recommendations

The 4-1734531-4 is the designated substitute for the obsolete 88333-044LF. Selection of this part is based on:

• Product Status Alignment: The substitute is active and currently available, addressing the obsolescence of the original part
• Compliance Certification: Both parts maintain UL94 V-0 flammability compliance
• RoHS Compliance: The substitute meets RoHS requirements, supporting modern regulatory standards
• Mechanical & Electrical Equivalence: All critical mating parameters, contact configurations, and termination methods are identical

The substitute part is suitable for direct replacement in existing designs without modification to PCB layouts or mating connector specifications.

Frequently Asked Questions (FAQ)

Q: Can the 4-1734531-4 be used as a direct replacement for the 88333-044LF?

A: Yes. Both connectors share identical pitch (0.079"), row spacing (0.079"), position count (44), mounting orientation (right-angle through-hole), and contact configuration (female socket, phosphor bronze, gold-plated). The connectors are mechanically and electrically compatible.

Q: What are the key differences between these two parts?

A: The primary differences are manufacturer (Amphenol ICC vs. TE Connectivity), series designation (Minitek® vs. AMPMODU), product status (obsolete vs. active), and minor variations in contact finish thickness and insulation height. The 4-1734531-4 includes specified operating temperature range (-40°C ~ 105°C) and voltage rating (250VAC), which were not provided for the original part.

Q: Are there packaging differences?

A: The 88333-044LF packaging is not specified in available data. The 4-1734531-4 is supplied in tube packaging.

Q: Does the substitute part meet the same flammability standards?

A: Yes. Both parts are rated UL94 V-0, meeting identical material flammability requirements.

Q: Is the substitute part RoHS compliant?

A: Yes. The 4-1734531-4 is RoHS compliant. RoHS status for the original 88333-044LF was not specified.
