EDSTL950/8 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The EDSTL950/8 is an 8-position terminal block header manufactured by On Shore Technology Inc., designed for right-angle solder mounting applications. This shrouded male pin header operates at 300 V UL and accommodates 0.197" (5.00mm) pitch connections. The component is Active status and ROHS3 compliant, making it suitable for modern electronic assemblies requiring reliable interconnection solutions.

Substitute parts become necessary when the primary part experiences supply constraints, extended lead times, or when design requirements permit alternative configurations that maintain electrical and mechanical compatibility within specified parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the EDSTL950/8 is determined by strict alignment of the following critical parameters:

• Position Count & Pitch: All substitutes must maintain 8 positions at 0.197" (5.00mm) pitch to ensure mechanical and electrical compatibility with mating connectors and PCB layouts.
• Header Type & Shrouding: All substitutes must be male pin headers with 4-side shrouding to maintain the same form factor and safety characteristics.
• Header Orientation: All substitutes must feature 90° right-angle configuration for identical mounting orientation.
• Voltage Rating: All substitutes must meet or exceed 300 V UL rating to maintain electrical safety margins.
• Mounting Method: Solder mounting is the primary requirement; through-hole variants are acceptable when solder termination is confirmed.
• Compliance: All substitutes must maintain ROHS3 compliance and MSL 1 rating for supply chain and assembly compatibility.

The two identified substitutes meet these criteria with documented variations in contact materials, housing materials, and operating temperature ranges that do not affect functional interchangeability within the specified electrical and mechanical envelope.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain Active product status and ROHS3 compliance, confirming ongoing manufacturer support and regulatory alignment for current production environments.

OSTOQ087151 offers expanded operating temperature range (-40°C ~ 115°C) compared to the primary part, with brass contact material and thermoplastic housing. The increased contact tail length (0.157" vs 0.138") and insulation height (0.157" vs 0.138") represent minor dimensional variations that require PCB layout verification for clearance compatibility.

796644-8 from TE Connectivity provides the widest inventory availability and includes documented current rating (15 A UL). The through-hole mounting designation and significantly increased insulation height (0.329") indicate a different physical profile that may require PCB redesign for mounting hole spacing and component clearance. The UL94 V-0 flammability rating provides enhanced material certification compared to unspecified ratings in other variants.

Selection between substitutes depends on PCB layout constraints, thermal operating requirements, and current handling specifications for the specific application circuit.

Frequently Asked Questions (FAQ)

Q: Can OSTOQ087151 be used as a direct replacement for EDSTL950/8?

A: OSTOQ087151 maintains electrical and mechanical compatibility through matching position count, pitch, header type, and voltage rating. The increased contact tail length (0.157" vs 0.138") and insulation height require verification that PCB solder pad spacing and component clearance accommodate the dimensional variation.

Q: What is the primary difference between 796644-8 and the other substitutes?

A: 796644-8 is designated as through-hole mounting with significantly increased insulation height (0.329" vs 0.138"), indicating a different physical profile. This variant requires PCB redesign for mounting hole positioning and may not be suitable for applications with space constraints or existing PCB layouts designed for the original part dimensions.

Q: Are all three parts ROHS3 compliant?

A: Yes. EDSTL950/8, OSTOQ087151, and 796644-8 all carry ROHS3 Compliant status, confirming compliance with current environmental and material restriction regulations.

Q: What is the operating temperature difference between substitutes?

A: EDSTL950/8 operates from -30°C to 105°C. OSTOQ087151 extends this range to -40°C ~ 115°C, providing 10°C lower minimum and 10°C higher maximum operating temperatures. 796644-8 operates from -40°C ~ 110°C. Selection depends on application thermal requirements.

Q: Does 796644-8 have current rating specifications?

A: Yes. 796644-8 is rated for 15 A UL current, while EDSTL950/8 and OSTOQ087151 do not specify current ratings in available documentation. Applications requiring documented current handling should reference 796644-8 specifications.

Q: What inventory levels are available for each part?

A: EDSTL950/8 has 934 units in stock, OSTOQ087151 has 1950 units, and 796644-8 has 1332 units available as new original inventory.
