Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the EDSTLZ975/6-SW is determined by the following critical parameters:

Primary Matching Criteria:

• 12 total positions with 2-level configuration
• 0.200" (5.08mm) pitch spacing
• 90° right angle orientation
• Male pin header with 2-side shrouding
• Solder-based termination
• 300 V UL voltage rating minimum
• UL94 V-0 flammability compliance

The substitute part 1725210000 (Weidmüller Omnimate SL series) satisfies these core electrical and mechanical requirements, enabling functional equivalence in applications requiring the EDSTLZ975/6-SW.

Parameter Comparison

Engineering Selection Recommendations

The 1725210000 (Weidmüller Omnimate SL) is the designated substitute for the obsolete EDSTLZ975/6-SW. Both components maintain identical pitch spacing, position count, orientation, and UL94 V-0 flammability compliance. The substitute part carries active product status with current manufacturing support and inventory availability.

Key considerations for selection:

• Both parts meet 300 V UL voltage requirements
• Housing materials differ (PA/Nylon vs. PBT), with PBT offering enhanced chemical resistance
• Operating temperature ranges overlap within -30°C to 100°C
• Mounting methodology differs (solder vs. through hole), requiring PCB design verification
• RoHS compliance is maintained across both generations

Frequently Asked Questions (FAQ)

Q: Can the 1725210000 directly replace the EDSTLZ975/6-SW in existing designs?

A: Functional equivalence is established through matching pitch, position count, voltage rating, and flammability compliance. PCB mounting hole patterns must be verified, as the original uses solder termination while the substitute uses through-hole mounting.

Q: What is the significance of the 12 positions arranged as 6 per level vs. 12 per level?

A: Both configurations deliver 12 total positions across 2 levels. The arrangement difference reflects internal contact layout but does not affect electrical or mechanical compatibility when pitch and total position count remain constant.

Q: Are there compliance differences between the two parts?

A: Both parts maintain UL94 V-0 flammability ratings and REACH compliance. The substitute carries current RoHS certification while the original is ROHS3 compliant. Both are suitable for applications requiring these certifications.

Q: What housing material differences exist?

A: The original uses Polyamide (PA/Nylon) while the substitute uses Polybutylene Terephthalate (PBT). PBT provides improved chemical and thermal stability in certain industrial environments.

Q: Is the operating temperature range difference significant?

A: The original operates -30°C to 105°C while the substitute operates -50°C to 100°C. Applications requiring operation above 100°C must use the original specification or identify alternative solutions.
