EDSTLZ976/8 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The EDSTLZ976/8 is a 16-position terminal block header manufactured by On Shore Technology Inc., designed for vertical solder mounting applications. This component features male pins with 4-side shrouding and operates within a 0.200" (5.08mm) pitch configuration across two levels of 8 positions each. The part maintains Active product status and is RoHS3 compliant, making it suitable for industrial and commercial electronic assemblies requiring reliable interconnection solutions.

Substitute parts become necessary when original inventory is unavailable, when design requirements permit alternative mounting technologies, or when sourcing from alternative manufacturers offers supply chain advantages while maintaining functional compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the EDSTLZ976/8 is determined by the following critical parameters that must remain consistent:

• Position Configuration: 16 total positions arranged as 2 levels × 8 positions per level
• Pitch Specification: 0.200" (5.08mm) center-to-center spacing
• Header Orientation: Vertical mounting orientation
• Pin Type: Male pins with shrouding
• Voltage Rating: Minimum 300 V (UL specification)
• Operating Temperature Range: Must accommodate -30°C to 105°C
• Flammability Rating: UL94 V-0 compliance required
• Regulatory Compliance: RoHS3 and REACH Unaffected status

The substitute part 1725710000 (Weidmüller Omnimate SL series) satisfies these core substitution criteria. Differences in shrouding configuration (2-side versus 4-side), mounting technology (through-hole versus solder), and housing material (PBT versus PA/Nylon) represent acceptable variations within the terminal block category, provided the electrical and mechanical interface requirements remain compatible with the application circuit board design.

Parameter Comparison

Engineering Selection Recommendations

Both the EDSTLZ976/8 and 1725710000 maintain Active product status and satisfy core regulatory requirements including UL94 V-0 flammability rating and RoHS compliance. Selection between these components depends on circuit board design specifications:

EDSTLZ976/8 Selection Criteria: Choose this component when the PCB design incorporates solder pad footprints for direct surface mounting. The 4-side shrouding provides enhanced EMI shielding and mechanical protection in densely populated assemblies. The compact insulation height (0.154") suits space-constrained applications.

1725710000 Selection Criteria: Choose this component when the PCB design includes through-hole mounting positions. The through-hole technology provides superior mechanical retention and rework capability. The increased insulation height (0.872") accommodates applications requiring greater clearance above the PCB surface. The PBT housing material offers enhanced chemical resistance compared to polyamide.

Both components operate within acceptable voltage and temperature ranges for standard industrial applications. The operating temperature differential (-50°C to 100°C for the substitute versus -30°C to 105°C for the original) represents a minor variation that does not restrict substitution in most applications.

Frequently Asked Questions (FAQ)

Q: Can the 1725710000 directly replace the EDSTLZ976/8 on an existing PCB?

A: Direct replacement requires PCB redesign. The EDSTLZ976/8 uses solder mounting technology with surface-mount pads, while the 1725710000 requires through-hole mounting positions. The contact tail length differs (0.154" versus 0.126"), and the insulation height differs significantly (0.154" versus 0.872"). PCB layout modification is necessary for mechanical and electrical compatibility.

Q: Are the electrical specifications equivalent?

A: Yes. Both components maintain 300 V UL voltage rating, support 16-position configuration at 0.200" (5.08mm) pitch, and comply with UL94 V-0 flammability requirements. The substitute part provides higher current capacity (10 A UL / 14 A IEC) compared to the original specification, which does not restrict substitution.

Q: What is the significance of the shrouding difference (4-side versus 2-side)?

A: Shrouding configuration affects EMI performance and mechanical protection. The 4-side shrouding on the EDSTLZ976/8 provides complete enclosure of the pin field, offering superior electromagnetic shielding and protection against accidental contact. The 2-side shrouding on the 1725710000 provides partial enclosure, suitable for applications with less stringent EMI requirements or where accessibility to the pin field is necessary.

Q: Do both parts comply with current regulatory standards?

A: Yes. The EDSTLZ976/8 is RoHS3 compliant, and the 1725710000 is RoHS compliant. Both maintain REACH Unaffected status and EAR99 export classification. Both are classified under HTSUS code 8536.69.4040.

Q: What are the packaging and inventory considerations?

A: Both components are available in bulk packaging. The EDSTLZ976/8 has 1099 pieces in stock, and the 1725710000 has 1038 pieces in stock. Packaging format does not affect electrical or mechanical compatibility.
