Key Parameters

Substitute Part Grouping Explanation

The substitute part 1726780000 (Weidmüller Omnimate SL series) qualifies as an equivalent based on the following critical parameters:

Matching Parameters:

• 12-position configuration
• 0.200" (5.08mm) pitch spacing
• Vertical orientation
• Male pin header type
• Solder termination capability
• 300 V UL voltage rating
• UL94 V-0 flammability compliance
• Active product status

Differing Parameters:

• Shrouding configuration: 4-side (main part) vs. 2-side (substitute)
• Mounting method: Solder (main part) vs. Through Hole (substitute)
• Positions per level: 12 (main part) vs. 6 (substitute)
• Housing material: Polyamide/Nylon (main part) vs. Polybutylene Terephthalate/PBT (substitute)
• Operating temperature range: -30°C ~ 105°C (main part) vs. -50°C ~ 100°C (substitute)

The substitute part maintains functional compatibility through matching pitch, position count, voltage rating, and flammability standards. Differences in shrouding, mounting method, and housing material must be evaluated against specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

Both the EDSTLZ976/6 and 1726780000 maintain active product status with full RoHS compliance and UL94 V-0 flammability certification, ensuring regulatory alignment for industrial applications.

The EDSTLZ976/6 is specified for solder mounting with 4-side shrouding, providing enhanced EMI shielding and mechanical protection in densely populated PCB layouts. The 105°C upper operating temperature supports high-temperature environments.

The 1726780000 substitute offers through-hole mounting with 2-side shrouding and extends the lower operating temperature to -50°C, making it suitable for colder environments. The specified current ratings (14 A IEC, 10 A UL) and copper alloy contacts with tin finish provide additional electrical performance data.

Selection between these parts depends on PCB assembly method (solder vs. through-hole), thermal requirements, and shrouding necessity for the specific application. Both parts satisfy the core 12-position, 5.08mm pitch, 300V UL requirement.

Frequently Asked Questions (FAQ)

Q: Can the 1726780000 directly replace the EDSTLZ976/6 on an existing PCB?

A: Direct replacement requires PCB redesign. The EDSTLZ976/6 uses solder mounting pads, while the 1726780000 requires through-hole mounting. The different shrouding configurations (4-side vs. 2-side) also affect board layout and component spacing.

Q: What is the significance of the shrouding difference?

A: The 4-side shrouding on the EDSTLZ976/6 provides complete EMI containment and mechanical protection on all sides. The 2-side shrouding on the 1726780000 provides partial protection, typically sufficient for standard industrial applications but less effective in high-EMI environments.

Q: Are both parts suitable for the same voltage applications?

A: Both parts support 300 V UL rating. The 1726780000 additionally specifies 400 V IEC rating, providing broader compliance for international applications. Voltage selection should be based on application requirements and regional standards.

Q: How do the operating temperature ranges affect part selection?

A: The EDSTLZ976/6 operates from -30°C to 105°C, supporting higher temperature environments. The 1726780000 operates from -50°C to 100°C, extending cold-temperature capability. Application thermal requirements determine which range is appropriate.

Q: What packaging considerations apply to these parts?

A: Both parts are supplied in bulk packaging. The EDSTLZ976/6 has 1062 units in stock, while the 1726780000 has 1204 units available. Bulk packaging is standard for terminal block headers and does not affect electrical or mechanical compatibility.
