Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the Phoenix Contact 1766699 are qualified based on the following critical parameters:

• Position Count & Pitch: 5 positions at 0.295" (7.50mm) spacing
• Connector Type: Header with male pins, 4-side shrouded configuration
• Mounting & Termination: Through-hole solder termination
• Electrical Ratings: UL ratings of 15 A at 300 V minimum
• Mechanical Compatibility: Insulation height of 0.472" (12.00mm) and contact tail length within acceptable range
• Compliance: UL94 V-0 flammability rating and RoHS compliance

The identified substitutes—Molex 0393720005 and Weidmüller 1629160000—meet these core criteria and are suitable for direct replacement in applications requiring equivalent electrical performance and mechanical fit.

Parameter Comparison

Engineering Selection Recommendations

All three components—Phoenix Contact 1766699, Molex 0393720005, and Weidmüller 1629160000—carry Active product status and meet UL94 V-0 flammability requirements. Both substitute parts maintain RoHS compliance (ROHS3 for Molex, RoHS for Weidmüller) and are suitable for applications requiring equivalent electrical performance at 15 A and 300 V UL ratings.

Selection between these parts should be based on:

• Supply Chain Availability: Phoenix Contact 1766699 (941 pcs), Molex 0393720005 (1152 pcs), Weidmüller 1629160000 (926 pcs) are all in stock
• Housing Material Preference: Phoenix Contact and Molex use Polyamide (PA), Nylon; Weidmüller uses Polybutylene Terephthalate (PBT)
• Contact Material: Phoenix Contact unspecified; Molex uses Phosphor Bronze; Weidmüller uses Copper Alloy
• IEC Ratings: Weidmüller offers higher IEC ratings (18.5 A at 800 V) compared to Phoenix Contact (12 A at 630 V)
• Operating Temperature Range: Weidmüller specifies -50°C to 100°C; Phoenix Contact and Molex do not specify operating temperature limits

Frequently Asked Questions (FAQ)

Q: Can Molex 0393720005 directly replace Phoenix Contact 1766699?

A: Yes. Both components share identical position count (5), pitch (7.50mm), connector type (male pins, 4-side shrouded), mounting method (through-hole solder), and UL electrical ratings (15 A at 300 V). Mechanical compatibility is confirmed by matching insulation height (0.472"). Contact tail length differs slightly (0.138" vs 0.154"), but this does not affect functional compatibility in standard through-hole applications.

Q: What are the key differences between Weidmüller 1629160000 and the original Phoenix Contact part?

A: The Weidmüller substitute provides higher IEC electrical ratings (18.5 A at 800 V versus 12 A at 630 V) and specifies an operating temperature range (-50°C to 100°C). Housing material differs (PBT versus Polyamide), and contact tail length is shorter (0.126" versus 0.154"). All UL ratings and mechanical dimensions critical to substitution remain equivalent.

Q: Are all three parts RoHS compliant?

A: Yes. Phoenix Contact 1766699 and Weidmüller 1629160000 are RoHS Compliant. Molex 0393720005 is ROHS3 Compliant, which represents an updated compliance standard. All three meet RoHS requirements for hazardous substance restrictions.

Q: What is the significance of the 0.295" (7.50mm) pitch specification?

A: Pitch defines the center-to-center spacing between adjacent contact positions. The 7.50mm pitch is a standard spacing for industrial terminal block headers. All three parts maintain this identical pitch, ensuring mechanical and electrical compatibility with mating connectors and PCB layouts designed for this specification.

Q: Can these parts be used interchangeably in high-temperature applications?

A: Weidmüller 1629160000 explicitly specifies an operating temperature range of -50°C to 100°C. Phoenix Contact 1766699 and Molex 0393720005 do not provide operating temperature specifications in the available data. For applications requiring defined temperature performance, Weidmüller is the documented choice.
