Substitute Part Grouping Explanation

Substitution eligibility for the EDSTLZ965/3 is determined by strict alignment of the following critical parameters:

Number of Positions: Must be 3
Pitch: Must be 0.300" (7.62mm)
Header Orientation: Must be Vertical
Type: Must be Header with Male Pins and Shrouded (4 Side) configuration
Voltage Rating: Must meet or exceed 300 V UL specification
Operating Temperature Range: Must encompass or exceed -30°C ~ 105°C
RoHS Compliance: Must maintain ROHS3 Compliant status

Two equivalent parts meet these substitution criteria:

OSTOQ030150 (On Shore Technology Inc.) - Direct electrical and mechanical equivalent with identical pitch, position count, and voltage rating. Differs in contact tail length and insulation height by minor tolerances (0.003" and 0.003" respectively). Solder mounting type maintained.
796980-3 (TE Connectivity AMP Connectors, Buchanan series) - Meets core electrical specifications with identical pitch, position count, and voltage rating. Mounting method differs (Through Hole vs. Solder), and insulation height is significantly greater (0.472" vs. 0.154"), requiring PCB layout verification before substitution.

Engineering Selection Recommendations

OSTOQ030150 is the primary equivalent substitute for EDSTLZ965/3. Both parts are manufactured by On Shore Technology Inc., share identical electrical specifications (300 V UL, -30°C ~ 105°C operating range), and employ solder mounting. Contact tail and insulation height differences are within 0.003" tolerance, making this substitution suitable for direct replacement in existing PCB designs without layout modification. Both parts maintain ROHS3 compliance and active production status.

796980-3 (TE Connectivity) is a secondary equivalent suitable only when PCB design accommodates through-hole mounting and the increased insulation height of 0.472" (12.00mm). This part offers extended operating temperature range (-40°C ~ 110°C) and UL94 V-0 flammability rating. Substitution requires PCB layout verification due to mechanical differences. All three parts maintain ROHS3 compliance and active product status.

Frequently Asked Questions (FAQ)

Q: Can OSTOQ030150 be used as a direct replacement for EDSTLZ965/3 without PCB modification?

A: Yes. Both parts share identical pitch (0.300"), position count (3), voltage rating (300 V UL), operating temperature range (-30°C ~ 105°C), and solder mounting type. Contact tail length and insulation height differences (0.003" each) fall within standard manufacturing tolerances and do not require PCB redesign.

Q: What is the primary difference between OSTOQ030150 and 796980-3?

A: The primary difference is mounting type. OSTOQ030150 uses solder mounting with 0.154" insulation height, while 796980-3 uses through-hole mounting with 0.472" insulation height. This mechanical difference requires PCB layout verification before substitution.

Q: Are all three parts RoHS compliant?

A: Yes. EDSTLZ965/3, OSTOQ030150, and 796980-3 are all ROHS3 compliant and suitable for applications requiring RoHS certification.

Q: Which substitute part has the widest operating temperature range?

A: 796980-3 operates from -40°C ~ 110°C, compared to -30°C ~ 105°C for both EDSTLZ965/3 and OSTOQ030150. Selection depends on application temperature requirements.

Q: Can 796980-3 be used in applications originally designed for EDSTLZ965/3?

A: Substitution is possible only if the PCB design accommodates through-hole mounting and the increased insulation height (0.472" vs. 0.154"). Electrical specifications (300 V, 3-position, 0.300" pitch) are compatible, but mechanical layout verification is required.

Q: What is the inventory status of these parts?

A: EDSTLZ965/3 has 833 units in stock, OSTOQ030150 has 3392 units in stock, and 796980-3 has 1297 units in stock. All parts are in active production.
