Parameter Comparison

Engineering Selection Recommendations

Phoenix Contact 1377304 is the primary direct substitute. As an active product from the original manufacturer, it maintains identical electrical and mechanical specifications with the exception of contact shape (square versus rectangular) and increased current rating (2A versus 1.4A). The part is available in Tape & Reel packaging, suitable for high-volume production environments. ROHS3 compliance and UL94 V-0 flammability rating are maintained.

HARTING 15150682601000 (har-flex® series) provides cross-manufacturer equivalence with identical pitch, position count, and mounting configuration. The part is active and available in higher inventory quantities. Insulation height tolerance is within acceptable range. This option is suitable for applications where multi-source qualification is required.

Adam Tech ESMC-M-68-SGR-SMT-T/R (ESMC series) offers functional equivalence with phosphor bronze contact material and thermoplastic insulation as allowable variations. Current rating of 1.2A meets minimum requirements. This option provides additional sourcing flexibility for applications with less stringent material specifications.

All three substitute parts maintain compliance with RoHS3 and MSL 1 requirements, ensuring compatibility with standard manufacturing and storage protocols.

Frequently Asked Questions (FAQ)

Q: Can Phoenix Contact 1377304 directly replace 1714921 in existing designs?

A: Yes. Both parts share identical electrical and mechanical specifications for the 68-position, 1.27mm pitch configuration. The contact shape variation (square versus rectangular) does not affect mating compatibility. The higher current rating of 1377304 (2A) provides additional margin over the original 1.4A specification.

Q: What is the significance of the contact shape difference between rectangular and square?

A: Contact shape does not affect electrical performance or mating compatibility in this connector family. Both geometries provide equivalent contact resistance and current-carrying capacity within their respective ratings. The variation is a manufacturing design choice between suppliers.

Q: Are there packaging considerations when switching from Cut Tape to Tape & Reel?

A: Yes. Phoenix Contact 1377304 is supplied in Tape & Reel format, which is standard for automated assembly lines and high-volume production. Cut Tape packaging (used for 1714921, 15150682601000, and ESMC-M-68-SGR-SMT-T/R) is suitable for lower-volume or manual assembly operations. Packaging selection should align with production equipment capabilities.

Q: Does the insulation height variation between 0.165" and 0.167" affect board layout?

A: The 0.002" (0.05mm) variation is within standard manufacturing tolerance and does not require PCB layout modifications. Both dimensions are functionally equivalent for board-to-board or board-to-cable applications.

Q: What is the difference between Copper Alloy and Phosphor Bronze contact materials?

A: Both materials provide equivalent electrical conductivity and corrosion resistance for this application. Phosphor bronze (used in Adam Tech ESMC series) offers slightly enhanced spring properties and wear resistance. The choice between materials does not affect functional compatibility.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating, ensuring compatibility with standard manufacturing processes and storage requirements.

Q: Which substitute part should be selected for new production designs?

A: Phoenix Contact 1377304 is the recommended primary choice as the active equivalent from the original manufacturer. HARTING 15150682601000 is suitable for multi-source qualification strategies. Adam Tech ESMC-M-68-SGR-SMT-T/R provides additional sourcing flexibility when cost or availability considerations are primary factors.
