Phoenix Contact 1714877 Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1714877 is a 40-position receptacle connector with 0.050" (1.27mm) pitch, designed for surface mount right-angle board-to-board or cable 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 design support and procurement.

Engineering Selection Recommendations

Phoenix Contact 1337015 is the direct manufacturer equivalent. As an active product from the same manufacturer, it provides the highest assurance of form, fit, and function compatibility. The 1337015 features improved current rating (2.2A versus 1.4A) and maintains identical electrical and mechanical specifications. This part is recommended as the primary substitute for the obsolete 1714877.

HARTING 15250402601000 (har-flex® series) is a cross-manufacturer substitute meeting all core substitution criteria. It maintains the same connector geometry, pitch, row configuration, and environmental ratings. The insulation height is slightly reduced (0.120" versus 0.150"), which may require mechanical verification in space-constrained applications. This part is suitable for applications where cross-manufacturer sourcing is acceptable.

Adam Tech ESMC-F-40-SGR-SMT-T/R (ESMC series) is a secondary cross-manufacturer option. It meets all functional and mechanical requirements with gold-plated mating contacts and flash contact finish thickness. The insulation material differs (thermoplastic versus LCP), and the current rating is lower (1.2A). This part is suitable for general-purpose applications where the material change does not impact thermal or mechanical performance requirements.

Frequently Asked Questions (FAQ)

Q: Can Phoenix Contact 1337015 be used as a direct replacement for 1714877?

A: Yes. The 1337015 is functionally and mechanically equivalent to the 1714877. Both are 40-position receptacles with 0.050" pitch, surface mount right-angle configuration, and identical operating temperature range. The 1337015 is an active product and is the recommended substitute.

Q: What are the key differences between the HARTING and Adam Tech substitutes?

A: The HARTING 15250402601000 maintains LCP insulation material identical to the original part, while the Adam Tech ESMC-F-40-SGR-SMT-T/R uses thermoplastic insulation. The HARTING part has a lower insulation height (0.120" versus 0.150"), which may affect mechanical fit in certain applications. Current ratings differ: HARTING does not specify a current rating, while Adam Tech specifies 1.2A.

Q: Are all substitutes RoHS compliant?

A: Yes. All three substitute parts are ROHS3 compliant. The original 1714877 is RoHS compliant. All parts meet current environmental regulations.

Q: What packaging options are available for these substitutes?

A: Phoenix Contact 1337015 is supplied in Tape & Reel (TR) packaging. HARTING 15250402601000 is supplied in Cut Tape (CT) packaging. Adam Tech ESMC-F-40-SGR-SMT-T/R is supplied in Tape & Reel (TR) packaging. Packaging selection should align with assembly process requirements.

Q: Do these substitutes have identical insulation heights?

A: No. The original 1714877 has an insulation height of 0.150" (3.81mm). Phoenix Contact 1337015 is 0.149" (3.78mm), Adam Tech ESMC-F-40-SGR-SMT-T/R is 0.145" (3.68mm), and HARTING 15250402601000 is 0.120" (3.05mm). Verify mechanical clearance in your application before substitution.

Q: Which substitute offers the best current-carrying capacity?

A: Phoenix Contact 1337015 offers the highest specified current rating at 2.2A, compared to the original 1714877 at 1.4A and Adam Tech ESMC-F-40-SGR-SMT-T/R at 1.2A. HARTING 15250402601000 does not specify a current rating.
