Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1714923 is determined by strict alignment with the following critical parameters:

Connector type (Header)
Contact type (Male Pin)
Mating pitch (0.050" / 1.27mm)
Position count (80)
Row configuration (2 rows)
Row spacing (0.050" / 1.27mm)
Mounting style (Surface Mount, Right Angle)
Shrouding configuration (Shrouded - 4 Wall)
Termination method (Solder)
Fastening mechanism (Push-Pull)
Operating temperature range (-55°C ~ 125°C)
Flammability rating (UL94 V-0)
RoHS compliance (ROHS3)

All identified substitute parts meet these core electrical and mechanical requirements. Variations in contact shape, contact finish thickness, insulation height, and current rating are secondary parameters that may require design validation depending on application-specific constraints.

Engineering Selection Recommendations

Phoenix Contact 1377305 is the primary direct substitute. This part maintains Phoenix Contact COMBICON FP series compatibility and shares identical electrical and mechanical specifications with the original 1714923. The 1377305 is currently in active production status with higher current rating (2A versus 1.4A), providing enhanced performance margin. Packaging differs (Tape & Reel versus Cut Tape), which may affect procurement workflows but does not impact functional compatibility.

HARTING 15150802601000 provides cross-manufacturer equivalence within the har-flex® series. All critical mating parameters align with the original specification. This option offers the highest inventory availability (3368 units) and maintains full compliance with RoHS3 and UL94 V-0 requirements. Insulation height tolerance differs slightly (0.167" versus 0.165"), which remains within acceptable mechanical envelope constraints for standard board-to-board applications.

Adam Tech ESMC-M-80-SGR-SMT-T/R represents an alternative from a third manufacturer within the ESMC series. This part meets all core substitution criteria with identical pitch, position count, and row configuration. Contact material differs (Phosphor Bronze versus Copper Alloy), and insulation material is Thermoplastic rather than LCP. Current rating is 1.2A, which is lower than the original specification. This option is suitable for applications where the lower current rating does not present a constraint.

All three substitute parts maintain ROHS3 compliance, UL94 V-0 flammability rating, and MSL 1 moisture sensitivity classification, ensuring regulatory and environmental compatibility with the original design.

Frequently Asked Questions (FAQ)

Q: Can Phoenix Contact 1377305 be used as a direct replacement for 1714923?

A: Yes. Both parts are Phoenix Contact products with identical connector type, pitch, position count, row configuration, mounting style, and operating temperature range. The 1377305 is the active production equivalent with improved current rating (2A). Packaging format differs (Tape & Reel versus Cut Tape), which affects procurement but not functional performance.

Q: What are the key differences between the HARTING 15150802601000 and the original Phoenix Contact 1714923?

A: The HARTING part maintains all critical mating parameters (pitch, positions, rows, mounting, shrouding, termination, fastening). Differences include manufacturer (HARTING versus Phoenix Contact), series designation (har-flex® versus COMBICON FP), insulation height (0.167" versus 0.165"), and contact finish post material (Tin versus unspecified). These variations do not affect electrical or mechanical compatibility for standard board-to-board applications.

Q: Is the Adam Tech ESMC-M-80-SGR-SMT-T/R suitable for high-current applications?

A: The ESMC-M-80-SGR-SMT-T/R has a current rating of 1.2A, which is lower than both the original 1714923 (1.4A) and the Phoenix Contact 1377305 (2A). This part is suitable only for applications where the 1.2A current rating meets design requirements. Contact material (Phosphor Bronze) and insulation material (Thermoplastic) also differ from the original specification.

Q: Do all substitute parts meet RoHS3 and UL94 V-0 compliance?

A: Yes. All three substitute parts are ROHS3 compliant and carry UL94 V-0 flammability rating, matching the original 1714923 specification.

Q: What is the impact of packaging format differences on component selection?

A: The original 1714923 is supplied in Cut Tape (CT) & Digi-Reel® format. The Phoenix Contact 1377305 uses Tape & Reel (TR), and the HARTING 15150802601000 uses Cut Tape (CT). The Adam Tech ESMC-M-80-SGR-SMT-T/R uses Tape & Reel (TR). Packaging format affects procurement logistics and handling but does not impact electrical or mechanical performance. Selection should align with assembly line equipment and inventory management requirements.

Q: Are there mechanical envelope considerations when substituting these parts?

A: Insulation height varies slightly across substitutes (0.165" for 1714923 and ESMC-M-80-SGR-SMT-T/R versus 0.167" for 1377305 and 15150802601000). Contact length specifications also differ. These variations remain within typical PCB design tolerances for standard board-to-board connectors. Design validation is recommended if mechanical clearance is constrained.
