Key Parameters

Substitute Part Grouping Explanation

Substitution compatibility for the Phoenix Contact 1704220 is determined by the following critical parameters:

• Mechanical Compatibility: 8 positions, 0.197" (5.00mm) pitch, 180° free-hanging in-line orientation, and female socket configuration
• Electrical Performance: Current and voltage ratings must meet or exceed IEC specifications (14.6A @ 630V minimum)
• Termination Method: Screw-based termination with cage clamp mechanism
• Wire Acceptance: Support for 12-26 AWG (0.5-4mm²) wire gauges
• Regulatory Compliance: UL94 V-0 flammability rating and RoHS compliance

The Würth Elektronik 691385700008 qualifies as a substitute based on matching mechanical form factor, pitch, position count, orientation, and termination methodology. Both components share identical position configuration and wire entry angle, enabling direct functional replacement in equivalent circuit applications.

Engineering Selection Recommendations

The Würth Elektronik 691385700008 is the identified substitute for the obsolete Phoenix Contact 1704220. Selection should be based on the following engineering criteria:

Compliance and Availability: The Würth Elektronik part maintains active product status with confirmed inventory availability (999 pcs), whereas the Phoenix Contact component is obsolete. Both components satisfy UL94 V-0 flammability requirements and RoHS/ROHS3 compliance standards.

Electrical Ratings: The substitute provides higher IEC current capacity (16A vs. 14.6A) and UL current rating (14A vs. 10A). However, the IEC voltage rating is reduced (250V vs. 630V). Applications operating at or below 250V IEC specifications will experience no functional limitation. Systems requiring the full 630V IEC rating must evaluate alternative solutions.

Wire Gauge Compatibility: The substitute accepts 12-24 AWG (0.2-2.5mm²), which covers the majority of the original specification range. Wire gauges 25-26 AWG and cross-sections above 2.5mm² are not supported by the substitute and require alternative component selection.

Mechanical Interchangeability: Both components share identical 8-position, 5.00mm pitch, 180° free-hanging configuration, ensuring direct mechanical replacement in existing connector housings and mating interfaces.

Frequently Asked Questions (FAQ)

Q: Can the Würth Elektronik 691385700008 directly replace the Phoenix Contact 1704220 in all applications?

A: Direct replacement is possible for applications operating at or below 250V IEC and using wire gauges 12-24 AWG. Applications requiring 630V IEC operation or wire gauges 25-26 AWG must evaluate alternative components.

Q: What are the key mechanical compatibility factors?

A: Both components share identical position count (8), pitch (5.00mm), wire entry angle (180°), and free-hanging in-line mounting configuration. These parameters ensure mechanical interchangeability in connector housings and mating interfaces.

Q: Are both components RoHS compliant?

A: Yes. The Phoenix Contact 1704220 is RoHS Compliant, and the Würth Elektronik 691385700008 is ROHS3 Compliant. Both satisfy current RoHS regulatory requirements.

Q: What is the difference in termination methodology?

A: The Phoenix Contact component specifies screw-rising cage clamp termination, while the Würth Elektronik component specifies screw termination. Both employ screw-based wire termination compatible with standard cage clamp mechanisms.

Q: How do the wire gauge specifications differ?

A: The Phoenix Contact 1704220 accepts 12-26 AWG (0.5-4mm²). The Würth Elektronik 691385700008 accepts 12-24 AWG (0.2-2.5mm²). The substitute does not support 25-26 AWG wire gauges or cross-sections exceeding 2.5mm².

Q: What is the current inventory status?

A: The Phoenix Contact 1704220 is obsolete with 722 pcs in stock. The Würth Elektronik 691385700008 is active with 999 pcs in stock, providing assured long-term availability for new designs and system maintenance.
