Substitute Part Grouping Explanation

Substitution eligibility for the OSTET080252 is determined by the following critical parameters:

Pitch (0.300" / 7.62mm): All substitutes must maintain identical pitch for mechanical compatibility with mating connectors
Number of Positions (8): Pin count must remain constant
Mounting Type (Free Hanging In-Line): Physical form factor must match
Termination Style (Screw): Wire connection method must be screw-based
Wire Gauge Range (8-24 AWG): Acceptable wire sizes must overlap or exceed the original specification
Voltage Rating (300 V minimum): Electrical rating must meet or exceed the original
Material Flammability (UL94 V-0): Safety certification must be maintained
RoHS3 Compliance: Environmental compliance status must be equivalent or superior

Two substitute parts meet these criteria:

ET0802520000G (Amphenol Anytek): Direct substitute with female sockets, matching pitch and position count. Enhanced specifications include 600 V rating, 41 A current capacity, and extended temperature range (-40°C to 115°C).

ET0801520000G (Amphenol Anytek): Alternative substitute with blade sockets instead of female sockets. Maintains pitch, position count, and screw termination. Rated for 300 V and 32 A, with extended temperature range (-40°C to 115°C).

Engineering Selection Recommendations

ET0802520000G is the primary substitute for direct replacement applications. This part maintains socket type compatibility (female sockets) with the original OSTET080252, ensuring mechanical and electrical interchangeability. The higher voltage rating (600 V vs. 300 V) and specified current capacity (41 A) provide enhanced performance margins. Extended operating temperature range (-40°C to 115°C) accommodates broader environmental conditions. Both parts carry ROHS3 compliance and UL94 V-0 flammability certification, meeting regulatory requirements.

ET0801520000G serves as an alternative where blade socket configuration is acceptable. This part maintains the same pitch, position count, and screw termination method. The voltage rating matches the original specification (300 V), with slightly lower current capacity (32 A). Selection of this part requires confirmation that the mating connector accepts blade sockets rather than female sockets.

Both substitutes are active products with established supply availability, eliminating obsolescence concerns associated with the original OSTET080252.

Frequently Asked Questions (FAQ)

Q: Can ET0802520000G directly replace OSTET080252 without design modifications?

A: Yes. ET0802520000G maintains identical pitch (0.300" / 7.62mm), position count (8), socket type (female), and termination method (screw). The connector will mate with existing receptacles designed for OSTET080252.

Q: What is the primary difference between ET0802520000G and ET0801520000G?

A: Socket type differs. ET0802520000G features female sockets (matching OSTET080252), while ET0801520000G features blade sockets. This affects mating connector compatibility. Verify your mating connector type before selection.

Q: Are both substitutes RoHS3 compliant?

A: Yes. Both ET0802520000G and ET0801520000G are ROHS3 compliant and carry UL94 V-0 flammability certification, matching the environmental and safety standards of the original part.

Q: Does the higher voltage rating of ET0802520000G (600 V vs. 300 V) affect compatibility?

A: No. Higher voltage rating indicates enhanced electrical capability and does not affect mechanical or functional compatibility. The part operates safely at the original 300 V specification and below.

Q: What wire gauge range is supported by the substitutes?

A: Both substitutes accept 8-24 AWG wire, matching the original OSTET080252 specification. ET0801520000G additionally supports 2.5-10mm² metric wire gauge range.

Q: Is the screw torque specification identical across all three parts?

A: Yes. All three parts specify 0.79 Nm (7.0 Lb-In) screw torque, ensuring consistent installation procedures.

Q: What is the inventory status of the substitute parts?

A: ET0802520000G has 757 pieces in stock. ET0801520000G has 700 pieces in stock. Both are active products with established supply chains.
