EDSTLZ976/5 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The EDSTLZ976/5 is a 10-position vertical terminal block header manufactured by On Shore Technology Inc., designed for solder mounting applications. This component features male pins with 4-side shrouding and operates within a temperature range of -30°C to 105°C. The part is currently active in production with 857 units in stock and maintains full RoHS3 compliance.

Identifying equivalent and substitute parts is necessary when the primary component becomes unavailable, when procurement lead times require alternative sourcing, or when design flexibility permits functional alternatives that meet the same electrical and mechanical requirements.

Substitute Part Grouping Explanation

Substitution eligibility for terminal block headers is determined by strict alignment of core electrical and mechanical parameters. The following criteria establish functional equivalence:

Critical Parameters for Substitution:

Number of positions: Must equal 10
Pitch spacing: Must equal 0.200" (5.08mm)
Header orientation: Must be vertical
Voltage rating: Must meet or exceed 300 V UL specification
Mounting compatibility: Solder or through-hole mounting acceptable for PCB integration
Shrouding configuration: Acceptable with 2-side or 4-side shrouding
Material flammability: Must maintain UL94 V-0 rating
RoHS compliance: Must be RoHS compliant

The substitute part 1726770000 (Weidmüller Omnimate SL series) satisfies all critical substitution parameters. While it features 2-side shrouding instead of 4-side, through-hole mounting instead of solder mounting, and different housing material (PBT vs. Nylon), these variations remain within acceptable substitution boundaries for terminal block headers with identical pitch, position count, and voltage specifications.

Engineering Selection Recommendations

Both the EDSTLZ976/5 and 1726770000 maintain active production status and full regulatory compliance. The EDSTLZ976/5 is RoHS3 compliant, while the 1726770000 is RoHS compliant. Both components carry UL94 V-0 flammability ratings and are unaffected by REACH regulations.

Selection between these components should be based on PCB design requirements. The EDSTLZ976/5 is optimized for solder mounting applications with 4-side shrouding, while the 1726770000 accommodates through-hole mounting with 2-side shrouding. The operating temperature range of the EDSTLZ976/5 extends to 105°C, compared to 100°C for the 1726770000, making the On Shore component suitable for higher-temperature environments. Both components support 300 V UL voltage specifications and maintain identical 10-position, 5.08mm pitch configurations.

Frequently Asked Questions (FAQ)

Q: Can the 1726770000 directly replace the EDSTLZ976/5 on existing PCBs?

A: Direct replacement depends on PCB design. The EDSTLZ976/5 uses solder mounting, while the 1726770000 uses through-hole mounting. PCB footprints must accommodate the respective mounting style. The 4-side shrouding of the EDSTLZ976/5 differs from the 2-side shrouding of the 1726770000, which may affect mechanical clearance in confined spaces.

Q: Are the electrical specifications equivalent?

A: Yes. Both components support 10 positions, 0.200" (5.08mm) pitch, vertical orientation, and 300 V UL voltage rating. Current ratings differ (EDSTLZ976/5 does not specify IEC current; 1726770000 specifies 14A IEC and 10A UL), but voltage specifications are identical.

Q: What is the difference in shrouding configuration?

A: The EDSTLZ976/5 features 4-side shrouding, providing protection on all four sides of the connector. The 1726770000 features 2-side shrouding, protecting two sides. This affects mechanical robustness and EMI shielding characteristics.

Q: Do both components meet the same compliance standards?

A: Both components are UL94 V-0 rated and RoHS compliant. The EDSTLZ976/5 is RoHS3 compliant, while the 1726770000 is RoHS compliant. Both are REACH unaffected and carry EAR99 ECCN classification.

Q: What is the temperature operating range difference?

A: The EDSTLZ976/5 operates from -30°C to 105°C, while the 1726770000 operates from -50°C to 100°C. The On Shore component supports higher maximum temperatures, making it suitable for applications requiring operation above 100°C.
