Phoenix Contact 1714889 Rectangular Connector - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1714889 is an 80-position receptacle connector with 0.050" (1.27mm) pitch designed for surface mount applications. This connector features gold-plated mating contacts, push-pull fastening, and operates across -55°C to 125°C. The part is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing production and maintenance applications.

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1714889 is determined by strict alignment with the following critical parameters:

80-position configuration with 2-row layout
0.050" (1.27mm) mating pitch and row spacing
Surface mount termination with solder connection
Push-pull fastening mechanism
Gold-plated mating contacts
Operating temperature range of -55°C to 125°C
UL94 V-0 flammability rating
Board-to-board or board-to-cable connectivity

The three substitute parts identified meet these core electrical and mechanical requirements. Variations in current rating, contact material, insulation material, and packaging format do not preclude functional equivalence within the specified parameter set.

Engineering Selection Recommendations

Phoenix Contact 1374883 is the primary direct substitute. Both parts originate from Phoenix Contact, share identical mechanical and electrical specifications, and maintain active product status. The 1374883 offers higher current rating (2.1A versus 1.4A) and ROHS3 compliance, providing enhanced capability for new designs while maintaining full backward compatibility.

HARTING 15220802601000 serves as a cross-manufacturer alternative within the har-flex® series. This part meets all critical substitution parameters and carries active product status with ROHS3 and REACH compliance. The mated stacking height range (10.8mm ~ 13.8mm) accommodates the original part's specifications.

Adam Tech ESMC-F-80-SGS-SMT-B-PP-T/R represents a secondary alternative from a different manufacturer. While contact material differs (phosphor bronze versus copper alloy) and insulation material is thermoplastic rather than LCP, the part maintains all critical electrical and mechanical parameters. Current rating is 1.2A, which is within acceptable range for applications rated at 1.4A or lower.

Frequently Asked Questions (FAQ)

Q: Can Phoenix Contact 1374883 directly replace 1714889 in existing designs?

A: Yes. Both parts share identical pitch (0.050"), position count (80), row configuration (2), mounting type (surface mount), contact finish (gold), and fastening mechanism (push-pull). The 1374883 is the direct manufacturer equivalent with active product status.

Q: What are the key differences between the substitute parts?

A: Phoenix Contact 1374883 is the closest match with identical specifications except higher current rating. HARTING 15220802601000 introduces cross-manufacturer compatibility with equivalent performance. Adam Tech ESMC-F-80-SGS-SMT-B-PP-T/R differs in contact material (phosphor bronze) and insulation material (thermoplastic) but maintains mechanical and electrical compatibility.

Q: Are all substitutes RoHS compliant?

A: The original 1714889 is RoHS Compliant. All three substitutes carry ROHS3 Compliant status, which represents enhanced compliance requirements. This upgrade does not affect functional compatibility.

Q: Does packaging format affect substitution eligibility?

A: Packaging format (Cut Tape, Tape & Reel, Digi-Reel) does not affect electrical or mechanical compatibility. Selection should be based on procurement and assembly process requirements.

Q: What is the significance of the mated stacking height specifications?

A: Mated stacking heights define the vertical distance when connectors are mated. The original 1714889 specifies 10.8mm and 12.3mm. HARTING 15220802601000 provides 10.8mm ~ 13.8mm range, which encompasses the original specifications. Adam Tech ESMC-F-80-SGS-SMT-B-PP-T/R specifies 10.8mm, 12.3mm, and 13.9mm, also covering the original range.

Q: Can the Adam Tech part be used in applications requiring 1.4A current?

A: The Adam Tech ESMC-F-80-SGS-SMT-B-PP-T/R is rated at 1.2A. Applications requiring sustained 1.4A current should use Phoenix Contact 1374883 (2.1A) or verify that the Adam Tech part meets specific application current demands below its rated maximum.
