Phoenix Contact 1766563 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1766563 is a 2-position vertical terminal block header with male pins and 2-side shrouding, designed for 7.62mm pitch through-hole applications. This component is classified as Active product status and is RoHS3 compliant. Substitute parts may be required due to inventory constraints, application-specific pitch requirements, or regional component availability.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 1766563 is determined by the following critical parameters:

• Number of Positions: Must remain 2 positions
• Header Orientation: Must remain vertical
• Termination Style: Must remain solder
• Mounting Type: Must remain through hole
• Electrical Ratings: Current and voltage ratings must meet or exceed application requirements
• Compliance Standards: RoHS and REACH compliance status must be maintained
• Flammability Rating: UL94 V-0 rating must be preserved

The Weidmüller 1820170000 qualifies as a substitute based on matching core functional parameters: 2-position configuration, vertical orientation, solder termination, and through-hole mounting. However, this substitute introduces a different pitch specification (5.08mm vs. 7.62mm), which represents a mechanical incompatibility with existing PCB layouts designed for the original part.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1766563 maintains Active product status with RoHS3 compliance and REACH unaffected designation. The Weidmüller 1820170000 substitute maintains RoHS compliance and REACH unaffected status, with equivalent UL94 V-0 flammability rating.

Direct substitution of the Weidmüller 1820170000 for the Phoenix Contact 1766563 is not recommended for existing PCB designs due to pitch incompatibility (5.08mm vs. 7.62mm). The different pitch specification requires PCB layout modification and cannot be accommodated through mechanical adaptation.

For new designs where pitch flexibility exists, the Weidmüller 1820170000 offers higher current capacity under IEC standards (27.5A vs. 12A) while maintaining equivalent UL voltage ratings (300V). The reduced contact tail length (1.50mm vs. 3.90mm) may affect solder joint geometry and should be evaluated for specific assembly processes.

Frequently Asked Questions (FAQ)

Q: Can the Weidmüller 1820170000 be used as a direct replacement for the Phoenix Contact 1766563 on existing PCBs?

A: No. The pitch difference (5.08mm vs. 7.62mm) creates mechanical incompatibility with PCB footprints designed for the original part. PCB layout modification is required.

Q: What are the key functional similarities between these parts?

A: Both components share 2-position configuration, vertical orientation, solder termination, through-hole mounting, UL94 V-0 flammability rating, and MSL 1 moisture sensitivity level.

Q: How do the electrical ratings compare?

A: The Weidmüller 1820170000 provides higher IEC current capacity (27.5A vs. 12A) but lower IEC voltage rating (400V vs. 630V). UL ratings are equivalent at 300V, with the Weidmüller offering higher current (18.5A vs. 15A).

Q: Are both parts RoHS compliant?

A: Yes. The Phoenix Contact 1766563 is RoHS3 compliant. The Weidmüller 1820170000 is RoHS compliant. Both maintain REACH unaffected status.

Q: What is the impact of different contact tail lengths?

A: The Phoenix Contact 1766563 has a 3.90mm contact tail length versus 1.50mm for the Weidmüller 1820170000. This difference affects solder joint formation and PCB hole depth requirements.

Q: What packaging formats are available?

A: Phoenix Contact 1766563 is supplied in Bulk packaging. Weidmüller 1820170000 is supplied in Cut Tape (CT) packaging.
