Key Parameters

Substitute Part Grouping Explanation

Substitution of the Weidmüller 1726000000 is determined by strict equivalence across the following critical parameters:

• Connector Configuration: 28 positions, 14 per level, 2 levels
• Pitch and Orientation: 0.200" (5.08mm) vertical through-hole
• Connector Type: Header with male pins, shrouded on 2 sides
• Electrical Ratings: Current and voltage specifications (IEC and UL)
• Termination Method: Solder attachment
• Material Specifications: Copper alloy contacts, PBT housing, UL94 V-0 flammability rating
• Physical Dimensions: Contact tail length and insulation height

The substitute part Weidmüller 1726000000 must maintain identical mechanical interfaces and electrical performance characteristics to ensure direct compatibility in existing circuit board designs and connector mating applications.

Parameter Comparison

Engineering Selection Recommendations

The Weidmüller 1725770000 serves as an active substitute for the obsolete 1726000000. Both components maintain identical mechanical interfaces, connector configuration, and core electrical specifications across IEC and UL standards. The 1725770000 offers enhanced electrical performance with higher IEC current rating (14A vs. 7A) and voltage rating (400V vs. 250V), while maintaining UL voltage equivalence at 300V. The extended operating temperature range (-50°C to 100°C) provides additional thermal margin compared to the original part (-20°C to 100°C).

The primary physical difference is the contact tail length: the substitute part features a shorter tail (0.126" vs. 0.177"), which may require PCB design verification for through-hole mounting depth compatibility. The 1725770000 carries RoHS compliance certification and active product status, supporting long-term supply chain continuity. Both parts maintain identical UL94 V-0 flammability ratings and material composition.

Frequently Asked Questions (FAQ)

Q: Can the 1725770000 be used as a direct replacement for the 1726000000 in existing designs?

A: Mechanical compatibility is maintained across connector pitch, position count, shrouding configuration, and insulation height. The shorter contact tail length (0.126" vs. 0.177") requires verification that PCB through-hole depth accommodates the substitute part. Electrical performance is equivalent or superior across both IEC and UL standards.

Q: What are the key differences between these two parts?

A: The primary differences are contact tail length, operating temperature range, IEC electrical ratings, and product status. The 1725770000 provides higher IEC current and voltage ratings, extended low-temperature operation, and active product availability. Housing color differs (orange vs. black).

Q: Are there compliance or certification differences?

A: Both parts maintain UL94 V-0 flammability rating and tin contact mating finish. The 1725770000 carries RoHS compliance certification, while the 1726000000 status is not specified. Both are REACH unaffected and classified under ECCN EAR99.

Q: Does the contact tail length difference affect electrical performance?

A: Contact tail length does not affect electrical performance specifications. The difference impacts PCB mounting depth requirements and through-hole penetration. Design verification is necessary to confirm compatibility with existing PCB layouts.

Q: What is the packaging difference between these parts?

A: The 1726000000 packaging is not specified. The 1725770000 is supplied in bulk packaging. Inventory availability differs: 719 pcs for the original part and 937 pcs for the substitute.
