Substitute Part Grouping Explanation

The OSTOQ025551 qualifies as a direct substitute for the EDSTLZ951/2 based on the following critical parameters:

• Number of Positions: Both parts feature 2 positions
• Pitch: Both maintain 0.200" (5.08mm) spacing
• Header Orientation: Both are configured for 90° right-angle mounting
• Mounting Type: Both use solder termination
• Voltage Rating: Both rated at 300 V UL
• Operating Temperature Range: Both operate from -30°C to 105°C
• Material Flammability Rating: Both meet UL94 V-0 standard
• RoHS Compliance: Both are ROHS3 compliant
• Moisture Sensitivity Level: Both rated MSL 1 (Unlimited)

The OSTOQ025551 maintains functional and electrical equivalence with the EDSTLZ951/2 for standard terminal block header applications requiring these specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the EDSTLZ951/2 and OSTOQ025551 are active production parts from On Shore Technology Inc. with identical electrical and functional specifications. Selection between these parts should be based on:

• Inventory Availability: The OSTOQ025551 currently has higher stock levels (1028 units vs. 899 units)
• Physical Dimensions: The OSTOQ025551 features a longer contact tail length (0.157" vs. 0.138") and greater insulation height (0.157" vs. 0.138"), which may affect PCB layout and mating depth considerations
• Compliance Status: Both parts meet ROHS3 compliance and UL94 V-0 flammability requirements
• Supply Chain Continuity: Both parts maintain active production status with equivalent regulatory certifications

Frequently Asked Questions (FAQ)

Q: Can OSTOQ025551 be used as a direct replacement for EDSTLZ951/2?

A: Yes. Both parts share identical electrical ratings (300 V UL), operating temperature range (-30°C to 105°C), pitch (0.200"/5.08mm), position count (2), and mounting configuration (90° right-angle solder). Both are ROHS3 compliant with UL94 V-0 flammability ratings.

Q: What are the physical differences between these parts?

A: The OSTOQ025551 has a contact tail length of 0.157" (4.00mm) and insulation height of 0.157" (4.00mm), compared to 0.138" (3.50mm) for the EDSTLZ951/2. These dimensional differences may affect PCB hole depth and mating connector alignment.

Q: Are both parts suitable for the same voltage and temperature applications?

A: Yes. Both parts are rated for 300 V UL and operate across the identical temperature range of -30°C to 105°C.

Q: What is the moisture sensitivity level for these parts?

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

Q: Are there any compliance or certification differences?

A: No. Both parts are ROHS3 compliant, REACH unaffected, and meet UL94 V-0 material flammability standards.
