Engineering Selection Recommendations

All three parts maintain active product status and ROHS3 compliance, ensuring regulatory alignment and long-term availability.

OSTOQ105451 provides direct functional equivalence with identical pitch, position count, and voltage rating. This part offers an extended operating temperature range (-40°C ~ 115°C) compared to the original specification. The contact tail length and insulation height are slightly increased (0.157" / 4.00mm), which may require PCB layout verification to confirm mechanical clearance compatibility.

1-796638-0 from TE Connectivity maintains the same critical electrical parameters (10 positions, 5.08mm pitch, 300V rating, 90° right angle orientation). This part differs in mounting approach (through hole versus solder) and features a significantly increased insulation height (0.329" / 8.36mm). The extended operating temperature range (-40°C ~ 110°C) and UL current rating (15A) provide additional performance headroom. The TE Connectivity part is suitable for applications where through-hole mounting is acceptable and where the increased insulation height does not conflict with board design constraints.

Frequently Asked Questions (FAQ)

Q: Can OSTOQ105451 be used as a direct replacement for EDSTLZ950/10?

A: OSTOQ105451 meets all critical electrical and functional parameters. The primary consideration is the increased contact tail length (0.157" versus 0.138") and insulation height (0.157" versus 0.138"), which requires verification that PCB pad spacing and component clearances accommodate these dimensional changes.

Q: What is the key difference between OSTOQ105451 and 1-796638-0?

A: The primary difference is mounting type: OSTOQ105451 uses solder mounting (matching the original EDSTLZ950/10), while 1-796638-0 uses through-hole mounting. Additionally, 1-796638-0 has a significantly larger insulation height (0.329" versus 0.138"), which affects board-level integration. Both maintain the same 10-position, 5.08mm pitch configuration and 300V rating.

Q: Are there any compliance or regulatory differences between these parts?

A: All three parts are ROHS3 compliant and maintain active product status. No regulatory or compliance barriers exist for substitution.

Q: Does the increased operating temperature range of the substitute parts affect compatibility?

A: No. An extended operating temperature range represents an enhancement to the original specification. If the original application operates within -30°C ~ 105°C, both substitute parts will function within this range without degradation.

Q: What should be verified before implementing a substitution?

A: PCB layout compatibility must be confirmed, specifically: pad spacing alignment with the contact tail length, clearance verification for the insulation height, and mounting hole positioning for the selected mounting type (solder or through-hole).
