EDSTLZ975/10-SW Terminal Block Header Equivalent & Substitute Parts

Part Overview

The EDSTLZ975/10-SW is a 20 position terminal block header manufactured by On Shore Technology Inc., featuring male pins with 2-side shrouding and 90° right angle solder termination. This component is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing system support and new design implementations. The part operates within a temperature range of -30°C to 105°C and meets UL94 V-0 flammability requirements with ROHS3 compliance.

Substitute Part Grouping Explanation

Substitution eligibility for the EDSTLZ975/10-SW is determined by strict alignment of the following critical parameters:

Position count and arrangement (20 positions, 10 per level, 2 levels)
Pitch specification (0.200" / 5.08mm)
Header orientation (90° right angle)
Connector type (male pins, 2-side shrouded)
Voltage rating (minimum 300 V UL)
Flammability compliance (UL94 V-0)
RoHS compliance status

The substitute part 1725250000 (Weidmüller Omnimate SL series) meets all critical substitution criteria. While termination method differs (through hole vs. solder), both achieve equivalent electrical and mechanical function within the specified parameter envelope. The substitute maintains position count, pitch, orientation, shrouding configuration, voltage rating, and flammability compliance.

Engineering Selection Recommendations

The 1725250000 (Weidmüller Omnimate SL) terminal block header is a direct functional equivalent for the obsolete EDSTLZ975/10-SW. Both components satisfy identical electrical specifications (300 V UL rating), mechanical configuration (20 positions at 5.08mm pitch, 90° right angle orientation), and safety compliance (UL94 V-0 flammability rating, RoHS compliance).

The substitute part carries active product status, ensuring ongoing availability and supply chain continuity. Both components maintain equivalent shrouding configuration and male pin termination, supporting identical mating interface requirements.

The operating temperature range of the substitute (-50°C to 100°C) overlaps substantially with the original part's range (-30°C to 105°C). Applications operating within -30°C to 100°C encounter no temperature-related constraints with the substitute.

Frequently Asked Questions (FAQ)

Q: Can the 1725250000 directly replace the EDSTLZ975/10-SW in existing designs?

A: Yes. Both components share identical position count (20), pitch (5.08mm), orientation (90° right angle), shrouding configuration (2-side male pins), and voltage rating (300 V UL). Mechanical and electrical interfaces are equivalent.

Q: What is the difference between solder and through-hole termination in this context?

A: The original EDSTLZ975/10-SW uses solder termination; the substitute 1725250000 uses through-hole termination. Both methods achieve permanent electrical connection to PCB traces. Through-hole termination provides equivalent reliability and current-carrying capacity for the specified 300 V UL rating.

Q: Are there temperature operating range differences I should consider?

A: The original part operates -30°C to 105°C; the substitute operates -50°C to 100°C. For applications within -30°C to 100°C, both parts are suitable. Applications requiring operation above 100°C should retain the original part specification or identify alternative solutions.

Q: Does the substitute maintain RoHS compliance?

A: Yes. The 1725250000 is RoHS compliant, meeting the same environmental and hazardous substance restrictions as the original ROHS3-compliant part.

Q: Why is the original part listed as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The substitute part, carrying active status, ensures continued component availability for system maintenance and new implementations.
