EDSTL950/2-OE Equivalent & Substitute Parts

Part Overview

The EDSTL950/2-OE is a 2-position terminal block header manufactured by On Shore Technology Inc. This component features male pins with shrouded design on both sides, 0.197" (5.00mm) pitch, and 90° right-angle orientation for solder mounting applications. The part is currently active in production with 1,026 units in stock. Alternative models may be required due to inventory constraints, supply chain considerations, or specific application requirements for contact material or insulation specifications.

Key Parameters

Substitute Part Grouping Explanation

The OSTOQ027051 qualifies as a direct substitute for the EDSTL950/2-OE based on the following critical parameters:

Matching Parameters:

• Number of positions: 2
• Positions per level: 2
• Number of levels: 1
• Pitch: 0.197" (5.00mm)
• Header orientation: 90°, Right Angle
• Type: Header, Male Pins, Shrouded (2 Side)
• Mounting type: Solder
• Voltage - UL: 300 V
• Operating temperature: -30°C ~ 105°C
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Variations in Secondary Parameters: The substitute part differs in contact tail length (0.157" vs. 0.138"), insulation height (0.157" vs. 0.138"), contact material (Brass vs. unspecified), and contact mating finish (Tin vs. unspecified). These variations do not affect functional equivalence for standard terminal block applications within the specified electrical and thermal parameters.

Parameter Comparison

Engineering Selection Recommendations

Both the EDSTL950/2-OE and OSTOQ027051 are active products from On Shore Technology Inc. with identical electrical ratings (300 V UL), thermal operating range (-30°C ~ 105°C), and compliance certifications (ROHS3 Compliant, REACH Unaffected, MSL 1). Both parts meet the same regulatory and environmental standards for terminal block applications.

Selection between these parts should be based on:

• Inventory availability: EDSTL950/2-OE has 1,026 units in stock; OSTOQ027051 has 730 units in stock
• Physical dimensions: OSTOQ027051 has slightly longer contact tail length (0.157" vs. 0.138") and insulation height (0.157" vs. 0.138"), which may affect PCB layout or connector mating depth
• Material specifications: OSTOQ027051 specifies Brass contact material with Tin mating finish, while EDSTL950/2-OE does not specify these details

Frequently Asked Questions (FAQ)

Q: Can OSTOQ027051 be used as a direct replacement for EDSTL950/2-OE?

A: Yes. Both parts share identical electrical specifications (300 V UL rating), thermal operating range (-30°C ~ 105°C), pitch (5.00mm), position count (2), orientation (90° right angle), and compliance certifications (ROHS3, MSL 1). The primary difference is contact tail length and insulation height, which must be verified against your specific PCB layout requirements.

Q: What is the significance of the contact tail length difference?

A: The OSTOQ027051 has a contact tail length of 0.157" (4.00mm) compared to 0.138" (3.50mm) for the EDSTL950/2-OE. This 0.019" (0.50mm) difference affects the depth of solder penetration and PCB hole positioning. Verify your PCB design accommodates this variation before substitution.

Q: Are both parts RoHS compliant?

A: Yes. Both EDSTL950/2-OE and OSTOQ027051 are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory requirements for electronic components.

Q: What is the Moisture Sensitivity Level (MSL) for these parts?

A: Both parts have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage, handling, or reflow processes.

Q: Do the housing material differences affect compatibility?

A: The EDSTL950/2-OE uses Polyamide (PA) Nylon, while OSTOQ027051 uses Thermoplastic. Both materials provide adequate insulation and mechanical support for the specified 300 V UL rating and -30°C ~ 105°C operating temperature range. Material selection does not affect electrical or thermal performance within these parameters.
