EDSTL955/2 Terminal Block Header Equivalent & Substitute Parts

Part Overview

The EDSTL955/2 is a 2-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 a 5.00mm pitch, operating across a temperature range of -30°C to 105°C with a rated voltage of 300V UL. The part maintains active product status and full RoHS3 compliance, making it suitable for industrial and commercial electronic assemblies requiring reliable interconnection solutions.

Equivalent and substitute parts are identified to provide design flexibility, accommodate supply chain variations, and support component lifecycle management in applications where the original specification allows for mechanical or electrical parameter variations within defined tolerances.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the EDSTL955/2 is determined by the following critical parameters: number of positions (2), pitch (5.00mm nominal), header orientation (vertical), voltage rating (300V UL minimum), operating temperature range compatibility, and RoHS3 compliance status.

The identified substitute parts are grouped into two categories based on mechanical and electrical compatibility:

Category 1 - Direct On Shore Technology Equivalent (OSTOQ027150): Maintains identical electrical specifications, position count, pitch, and orientation. Differs in contact tail length (0.157" vs 0.154"), insulation height (0.157" vs 0.154"), contact material (Brass vs unspecified), and housing material (Thermoplastic vs Polyamide/Nylon). Mounting type remains solder-based.

Category 2 - TE Connectivity Alternatives (796642-2, 282824-2): Both parts maintain 2-position configuration, vertical orientation, and 300V voltage rating. These parts feature through-hole mounting instead of solder mounting, higher operating temperature range (-40°C ~ 110°C), and enhanced material flammability rating (UL94 V-0). Pitch specifications differ: 796642-2 maintains 5.00mm pitch with 4-side shrouding, while 282824-2 uses 5.08mm pitch with 2-side shrouding. Contact tail lengths and insulation heights vary across this group.

Parameter Comparison

Engineering Selection Recommendations

All identified substitute parts maintain active product status and full RoHS3 compliance, ensuring regulatory alignment with the original EDSTL955/2 specification.

OSTOQ027150 provides the closest functional equivalence for direct replacement in solder-mount applications. This part preserves the mounting methodology and operating temperature range of the original design while maintaining identical electrical ratings and position configuration. Minor dimensional variations in contact tail length and insulation height fall within typical manufacturing tolerances for this component category.

796642-2 serves as an alternative for applications where through-hole mounting is acceptable and enhanced temperature performance (-40°C ~ 110°C) is beneficial. This TE Connectivity part maintains the 5.00mm pitch and 4-side shrouding configuration while providing UL94 V-0 flammability certification. The increased insulation height (0.472" vs 0.154") and specified current rating (15A) indicate suitability for higher-power interconnection requirements.

282824-2 represents a substitute option for designs accommodating a 5.08mm pitch tolerance and 2-side shrouding configuration. This part offers the same enhanced temperature range and flammability rating as 796642-2, with through-hole mounting capability. The pitch deviation of 0.08mm and reduced shrouding coverage require PCB layout verification before implementation.

Frequently Asked Questions (FAQ)

Q: Can OSTOQ027150 be used as a direct replacement for EDSTL955/2 in production?

A: Yes. OSTOQ027150 maintains identical electrical specifications (300V UL, 2 positions, 5.00mm pitch), vertical solder mounting, and operating temperature range (-30°C ~ 105°C). Both parts are RoHS3 compliant and active products. Minor dimensional differences in contact tail length (0.157" vs 0.154") and insulation height (0.157" vs 0.154") are within acceptable tolerances for standard terminal block applications.

Q: What are the key differences between solder-mount (EDSTL955/2, OSTOQ027150) and through-hole mount (796642-2, 282824-2) options?

A: Solder-mount parts are designed for surface-mount PCB assembly with shorter contact tails (4.60-4.00mm). Through-hole parts feature longer insulation heights (12.00mm) and are inserted through PCB holes for mechanical retention. Through-hole variants also provide enhanced temperature performance (-40°C ~ 110°C vs -30°C ~ 105°C) and UL94 V-0 flammability certification.

Q: Is the 5.08mm pitch of 282824-2 compatible with a 5.00mm pitch PCB layout?

A: No. The 0.08mm pitch difference between 282824-2 (5.08mm) and EDSTL955/2 (5.00mm) requires PCB layout modification. This part is suitable only for designs where the 5.08mm spacing is already specified or where layout adjustment is feasible.

Q: Do all substitute parts meet the same compliance requirements as EDSTL955/2?

A: Yes. All identified substitutes (OSTOQ027150, 796642-2, 282824-2) maintain RoHS3 compliance and active product status. TE Connectivity parts additionally provide UL94 V-0 flammability certification, which exceeds the original specification.

Q: What is the inventory availability difference between the main part and substitutes?

A: EDSTL955/2 has 830 units in stock. OSTOQ027150 offers significantly higher availability at 4,882 units. TE Connectivity alternatives provide 102,406 units (796642-2) and 937 units (282824-2), enabling supply chain flexibility across multiple sourcing options.
