Phoenix Contact 1714878 Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1714878 is a 50-position receptacle connector with 0.050" (1.27mm) pitch, designed for surface mount right-angle board-to-board 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 equivalent substitutes necessary for ongoing production and maintenance applications.

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1714878 is determined by the following critical parameters:

Connector Type & Contact Configuration: Must be receptacle with female socket contacts
Position Count & Pitch: Must maintain 50 positions at 0.050" (1.27mm) mating pitch with 2-row configuration
Mounting & Orientation: Must support surface mount, right-angle orientation
Electrical Characteristics: Operating temperature range of -55°C to 125°C and UL94 V-0 flammability rating
Termination Method: Solder termination with push-pull fastening
Insulation Material: Liquid Crystal Polymer (LCP) construction

All three substitute parts meet these core substitution criteria. Variations in contact finish specifications, insulation height tolerances, and current ratings represent acceptable engineering variations within the connector category.

Engineering Selection Recommendations

Phoenix Contact 1337018: This direct Phoenix Contact substitute is the primary recommendation for applications requiring continuity with the original manufacturer ecosystem. The part is active in production with higher current rating (2.2A) and improved compliance status (ROHS3). Insulation height tolerance (0.149") is within acceptable mechanical variation of the original specification.

HARTING 15250502601000: This har-flex® series connector provides an alternative from an established connector manufacturer. The part maintains all critical electrical and mechanical parameters with active product status and ROHS3 compliance. The reduced insulation height (0.120") represents a mechanical variation that may require PCB layout verification for clearance-critical applications.

Adam Tech ESMC-F-50-SGR-SMT-T/R: This ESMC series connector offers substitution capability with active product status and ROHS3 compliance. The thermoplastic insulation material differs from the LCP specification of the original part. Current rating (1.2A) is lower than the original specification and should be evaluated against application requirements.

Frequently Asked Questions (FAQ)

Q: Can I use part 1337018 as a direct replacement for 1714878?

A: Yes. Both are Phoenix Contact receptacles with identical 50-position, 0.050" pitch, surface mount right-angle configuration. The 1337018 is active in production and meets all core substitution criteria. Insulation height tolerance (0.149" vs. 0.150") is within acceptable mechanical variation.

Q: What is the primary difference between the HARTING and Adam Tech substitutes?

A: The HARTING 15250502601000 maintains LCP insulation material matching the original specification, while the Adam Tech ESMC-F-50-SGR-SMT-T/R uses thermoplastic insulation. The HARTING part has a lower insulation height (0.120"), which may affect PCB clearance in space-constrained designs.

Q: Are all substitutes RoHS compliant?

A: Yes. The original part is RoHS Compliant, and all three substitutes are ROHS3 Compliant, meeting current regulatory requirements.

Q: Does packaging format affect substitution eligibility?

A: No. Packaging format (Cut Tape, Tape & Reel, or Digi-Reel) does not affect electrical or mechanical compatibility. Selection should be based on procurement and assembly process requirements.

Q: What should I verify before implementing a substitute?

A: Verify PCB layout clearance for insulation height variations, confirm current rating adequacy for your application, and validate mating connector compatibility with the 0.050" pitch and push-pull fastening system.

Q: Is the Adam Tech substitute suitable for high-current applications?

A: The Adam Tech ESMC-F-50-SGR-SMT-T/R has a current rating of 1.2A, which is lower than both the original 1714878 (1.4A) and the Phoenix Contact 1337018 (2.2A). Application current requirements must be evaluated against this specification.
