EDSTLZ975/8-SW Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The EDSTLZ975/8-SW is a 16-position terminal block header manufactured by On Shore Technology Inc., featuring male pins with dual-side shrouding and 90° right-angle solder termination. This component is classified as obsolete, making identification of suitable substitute parts essential for ongoing design support and procurement continuity. The part operates within a 300V UL rating and -30°C to 105°C temperature range, with UL94 V-0 flammability compliance and ROHS3 certification.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the EDSTLZ975/8-SW is determined by strict alignment of the following critical parameters:

• Position Configuration: 16 positions arranged as 8 positions per level across 2 levels
• Pitch Specification: 0.200" (5.08mm) center-to-center spacing
• Header Type: Male pins with dual-side shrouding
• Orientation: 90° right-angle configuration
• Voltage Rating: Minimum 300V UL compliance
• Flammability: UL94 V-0 material rating
• Temperature Range: Operating capability within -30°C to 105°C
• Termination: Solder-compatible mounting interface

The substitute part 1725230000 (Weidmüller Omnimate SL series) satisfies all mandatory substitution criteria through equivalent position count, pitch specification, shrouded male pin design, right-angle orientation, and superior voltage/temperature ratings with maintained flammability compliance.

Parameter Comparison

Engineering Selection Recommendations

The Weidmüller 1725230000 terminal block header qualifies as a direct substitute for the obsolete EDSTLZ975/8-SW based on matching electrical specifications, position configuration, pitch, orientation, and flammability compliance. Both components maintain UL94 V-0 material ratings and satisfy 300V UL voltage requirements.

The substitute part carries active product status with current manufacturing availability, providing supply chain continuity for the obsolete On Shore component. Both parts are RoHS compliant and REACH unaffected, meeting regulatory requirements.

Physical differences exist in contact tail length (0.012" shorter on substitute) and insulation height (substitute is significantly taller at 1.032" versus 0.138"). These dimensional variations require verification against PCB layout constraints and mating connector specifications to confirm mechanical compatibility in the target application.

Operating temperature ranges differ slightly: the substitute operates -50°C to 100°C versus the original -30°C to 105°C. Applications requiring operation above 100°C or below -50°C must evaluate this specification gap against actual system requirements.

Frequently Asked Questions (FAQ)

Q: Can the Weidmüller 1725230000 directly replace the EDSTLZ975/8-SW in existing designs?

A: Electrical and functional compatibility is confirmed through matching position count, pitch, shrouded male pin configuration, right-angle orientation, and voltage/flammability ratings. However, physical dimensions differ, particularly insulation height and contact tail length. PCB layout and mating connector clearances must be verified before implementation.

Q: What are the critical parameters that define substitution eligibility for this terminal block header?

A: Substitution requires matching: 16-position configuration (8 per level, 2 levels), 0.200" (5.08mm) pitch, shrouded male pin design, 90° right-angle orientation, minimum 300V UL rating, UL94 V-0 flammability, and solder-compatible termination. Deviations in any parameter eliminate substitution eligibility.

Q: How do the housing materials differ between these components?

A: The original uses Polyamide (PA) nylon; the substitute uses Polybutylene Terephthalate (PBT). Both materials achieve UL94 V-0 flammability ratings. Material selection may affect chemical resistance and mechanical properties in specific environmental conditions.

Q: Are there temperature range limitations when substituting?

A: The original operates -30°C to 105°C; the substitute operates -50°C to 100°C. The substitute provides lower temperature capability but does not extend to the original's upper limit of 105°C. Applications requiring operation above 100°C cannot use this substitute.

Q: What dimensional considerations apply to this substitution?

A: Contact tail length differs by 0.012" (3.50mm original versus 3.20mm substitute). Insulation height is substantially different (0.138" original versus 1.032" substitute). These variations affect PCB footprint compatibility and clearance to adjacent components. Physical verification against design specifications is required.

Q: Are both components RoHS and REACH compliant?

A: Yes. The original is ROHS3 compliant; the substitute is RoHS compliant. Both are REACH unaffected. Regulatory compliance is maintained across the substitution.
