EDSTLZ975/7-SW Terminal Block Header Equivalent & Substitute Parts

Part Overview

The EDSTLZ975/7-SW is a 14-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 suitable substitute parts essential for ongoing system maintenance and new design implementations. The part operates within a 300V UL voltage rating and -30°C to 105°C temperature range, with UL94 V-0 flammability compliance and ROHS3 compliance status.

Substitute Part Grouping Explanation

Substitution of the EDSTLZ975/7-SW is determined by the following critical parameters:

Electrical Compatibility: Voltage rating (300V UL minimum), current capacity, and contact material specifications
Physical Compatibility: 14-position configuration, 0.200" (5.08mm) pitch, 90° right-angle orientation, and male pin shrouded (2-side) design
Termination Method: Solder or through-hole mounting capability
Environmental Compliance: UL94 V-0 flammability rating, RoHS compliance, and operating temperature range (-30°C to 105°C minimum)
Mechanical Dimensions: Contact tail length and insulation height within acceptable tolerance ranges for PCB mounting

The substitute part 1725220000 (Weidmüller Omnimate SL series) meets these core substitution criteria through equivalent electrical ratings, matching pitch and position count, compatible mounting methodology, and superior environmental compliance certifications.

Engineering Selection Recommendations

The 1725220000 (Weidmüller Omnimate SL) terminal block header serves as a direct functional substitute for the obsolete EDSTLZ975/7-SW. Both components maintain identical electrical specifications at 300V UL rating and equivalent 0.200" (5.08mm) pitch with 14-position, 2-level configuration. Both achieve UL94 V-0 flammability compliance and unlimited moisture sensitivity rating.

The Weidmüller substitute offers active product status with current manufacturing availability (947 pcs in stock versus 825 pcs for the obsolete On Shore part). The substitute provides enhanced current capacity specifications (17A IEC / 10A UL) and extended low-temperature operating range (-50°C versus -30°C minimum). Housing material differs (PBT versus PA/Nylon), with PBT offering superior chemical and thermal stability. Contact material specification (Copper Alloy) and tin mating finish provide documented corrosion resistance.

Mounting methodology differs between solder termination (original) and through-hole termination (substitute), requiring PCB layout verification. Mechanical dimensions show minor variation in contact tail length (0.126" versus 0.138") and insulation height (1.032" versus 0.138"), necessitating dimensional clearance confirmation during integration.

Frequently Asked Questions (FAQ)

Q: Can the 1725220000 directly replace the EDSTLZ975/7-SW without PCB modification?

A: Electrical and functional compatibility is confirmed through matching voltage ratings, pitch specifications, and position counts. However, mounting methodology differs (through-hole versus solder), and mechanical dimensions vary. PCB layout review is required to confirm pad spacing and clearance compatibility.

Q: What are the key differences in electrical performance between these parts?

A: Both components operate at 300V UL rating. The Weidmüller substitute provides higher current capacity (17A IEC / 10A UL) compared to the On Shore original. Voltage and current specifications are sufficient for equivalent circuit applications within the specified ratings.

Q: Are there compliance or certification concerns with substitution?

A: Both parts maintain UL94 V-0 flammability compliance, unlimited MSL rating, REACH unaffected status, and EAR99 export classification. RoHS compliance is confirmed for both (ROHS3 for original, RoHS for substitute). No compliance barriers exist for substitution.

Q: How do the operating temperature ranges compare?

A: The original EDSTLZ975/7-SW operates -30°C to 105°C. The Weidmüller substitute operates -50°C to 100°C. The substitute provides lower temperature capability but slightly reduced upper temperature limit. Application requirements must be verified against these ranges.

Q: What packaging and inventory considerations apply?

A: The original part is obsolete with 825 pcs available. The substitute is active production with 947 pcs in stock. For new designs or long-term supply requirements, the active substitute part is recommended to ensure continued availability.
