Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the EDSTL950/24 is determined by strict alignment of the following critical parameters:

• Position Count: 24 positions (non-negotiable for connector compatibility)
• Pitch Specification: 0.197" (5.00mm) center-to-center spacing
• Header Type: Male pins with 4-side shrouding
• Orientation: 90° right-angle configuration
• Mounting Method: Solder termination
• Voltage Rating: Minimum 300 V UL rating
• Regulatory Compliance: ROHS3 compliant status

The substitute part OSTOQ247151 meets all critical substitution criteria. Both parts are manufactured by On Shore Technology Inc., ensuring design consistency and functional equivalence within the specified electrical and mechanical parameters.

Parameter Comparison

Engineering Selection Recommendations

Both EDSTL950/24 and OSTOQ247151 are active production components with ROHS3 compliance and identical electrical specifications. Selection between these parts should be based on:

EDSTL950/24 is appropriate when the original design specification requires the exact contact tail length of 0.138" (3.50mm) and insulation height of 0.138" (3.50mm).

OSTOQ247151 is appropriate when the application can accommodate the extended contact tail length of 0.157" (4.00mm) and insulation height of 0.157" (4.00mm), or when the extended operating temperature range of -40°C ~ 115°C is required. This part also offers higher current inventory availability at 1154 units.

Both parts maintain identical pitch, position count, voltage rating, and mounting characteristics, ensuring functional equivalence in standard PCB solder applications.

Frequently Asked Questions (FAQ)

Q: Can OSTOQ247151 be used as a direct replacement for EDSTL950/24?

A: OSTOQ247151 is functionally equivalent for electrical and connector interface purposes. However, the contact tail length and insulation height differ by 0.019" (0.50mm). PCB layout and mechanical clearance must be evaluated to confirm compatibility with your specific application.

Q: What is the significance of the different contact tail lengths?

A: Contact tail length determines the depth of solder penetration into the PCB. EDSTL950/24 has a 0.138" (3.50mm) tail, while OSTOQ247151 has a 0.157" (4.00mm) tail. This affects PCB hole depth requirements and solder joint formation. Verify your PCB design accommodates the substitute part's dimensions.

Q: Are both parts RoHS compliant?

A: Yes, both EDSTL950/24 and OSTOQ247151 are ROHS3 compliant and meet current environmental regulations.

Q: Which part should I select for high-temperature applications?

A: OSTOQ247151 supports an extended operating temperature range of -40°C ~ 115°C compared to EDSTL950/24's -30°C ~ 105°C range. If your application requires operation at temperatures below -30°C or above 105°C, OSTOQ247151 is the appropriate selection.

Q: Is inventory availability a factor in part selection?

A: OSTOQ247151 currently has 1154 units in stock compared to 743 units for EDSTL950/24. If supply chain continuity is a consideration, OSTOQ247151 offers higher availability. However, electrical and mechanical compatibility must remain the primary selection criteria.

Q: Do both parts use the same housing material?

A: EDSTL950/24 uses Polyamide (PA) Nylon housing, while OSTOQ247151 uses Thermoplastic housing. Both materials are suitable for standard terminal block applications, but material composition differs between the two parts.
