Phoenix Contact 1714920 Rectangular Connector - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1714920 is a surface mount, right-angle rectangular connector header with 50 positions at 1.27mm pitch, designed for board-to-board or cable interconnection applications. This connector features shrouded 4-wall construction, gold-plated mating contacts, and operates across -55°C to 125°C. The part is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing design support and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1714920 is determined by strict alignment across the following critical parameters:

• Connector type (Header)
• Contact type (Male Pin)
• Mating pitch (0.050" / 1.27mm)
• Position count (50)
• Row configuration (2 rows)
• Row spacing (0.050" / 1.27mm)
• Mounting method (Surface Mount, Right Angle)
• Shrouding configuration (Shrouded - 4 Wall)
• Termination method (Solder)
• Fastening mechanism (Push-Pull)
• Operating temperature range (-55°C ~ 125°C)
• Material flammability (UL94 V-0)
• RoHS compliance (ROHS3)
• MSL rating (1 - Unlimited)

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 do not preclude functional substitution when primary parameters align.

Parameter Comparison

Engineering Selection Recommendations

Phoenix Contact 1377303 is the primary direct substitute for the obsolete 1714920. Both parts are manufactured by Phoenix Contact, share identical electrical and mechanical specifications across all critical parameters, and maintain active product status. The 1377303 is supplied in Tape & Reel packaging, suitable for automated assembly processes.

HARTING 15150502601000 and Adam Tech ESMC-M-50-SGR-SMT-T/R are functionally equivalent alternatives. Both maintain compliance with ROHS3, UL94 V-0 flammability rating, and MSL 1 specifications. The HARTING part is available in higher inventory quantity. The Adam Tech part features phosphor bronze contacts and thermoplastic insulation material, representing a design variant that meets all core substitution criteria.

All three substitute parts are actively manufactured and carry current product status, ensuring long-term availability and supply chain stability compared to the obsolete main part.

Frequently Asked Questions (FAQ)

Q: Can Phoenix Contact 1377303 directly replace 1714920 in existing designs?

A: Yes. The 1377303 maintains identical pitch, position count, row configuration, mounting orientation, shrouding, termination method, and operating temperature range. The primary difference is packaging format (Tape & Reel versus bulk), which does not affect functional performance.

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

A: All substitutes meet core electrical and mechanical requirements. The 1377303 uses LCP insulation identical to the main part. The HARTING 15150502601000 also uses LCP insulation. The Adam Tech ESMC-M-50-SGR-SMT-T/R uses thermoplastic insulation and phosphor bronze contacts instead of copper alloy. Contact shape varies (rectangular in the main part, square in substitutes), but this does not affect mating compatibility given identical pitch and position geometry.

Q: Are there current rating differences that affect substitution?

A: The main part is rated at 1.4A. The 1377303 is rated at 2A, providing higher current capacity. The Adam Tech part is rated at 1.2A. The HARTING part does not specify current rating. For applications requiring the original 1.4A specification, the 1377303 provides equivalent or superior performance.

Q: Do all substitutes meet the same compliance standards?

A: Yes. All substitute parts are ROHS3 compliant, UL94 V-0 rated, and carry MSL 1 (Unlimited) moisture sensitivity level, matching the original part's compliance profile.

Q: What packaging considerations apply to these substitutes?

A: The main part 1714920 is supplied in bulk packaging. All three substitutes are supplied in Tape & Reel format, standard for automated surface mount assembly. This packaging change does not affect component performance but may require process adjustment for manual assembly operations.
