• Termination Method: Screw-based wire termination
• Mounting Configuration: Free-hanging in-line orientation
• Electrical Ratings: Minimum 300 V UL voltage rating; wire gauge compatibility 8-24 AWG
• Environmental Compliance: UL94 V-0 flammability rating; ROHS3 compliance; operating temperature range support
• Mechanical Compatibility: Screw torque specification 0.79 Nm (7.0 Lb-In)

The substitute part ET0902500000G meets all critical substitution criteria while maintaining functional and electrical equivalence for the OSTET090250 application space.

Parameter Comparison

Engineering Selection Recommendations

The ET0902500000G from Amphenol Anytek serves as a direct functional equivalent to the obsolete OSTET090250. Selection of this substitute is supported by:

• Mechanical Compatibility: Identical pitch (7.62mm), position count (9), and mounting configuration ensure direct physical interchangeability in existing connector housings and mating interfaces.
• Electrical Equivalence: Matching wire gauge range (8-24 AWG), screw torque specification (0.79 Nm), and termination method provide identical electrical performance characteristics.
• Enhanced Ratings: The substitute provides superior voltage rating (600 V vs. 300 V) and extended operating temperature range (-40°C to 115°C vs. -33°C to 105°C), offering improved performance margins for demanding applications.
• Regulatory Compliance: Both components maintain UL94 V-0 flammability certification and ROHS3 compliance, ensuring continued adherence to applicable standards and regulations.
• Active Product Status: The substitute is currently in active production with confirmed inventory availability (732 pcs), eliminating supply chain risk associated with obsolete components.

Frequently Asked Questions (FAQ)

Q: Can ET0902500000G be used as a direct replacement for OSTET090250 in existing assemblies?

A: Yes. Both components share identical pitch (7.62mm), position count (9), termination method (screw), and mounting configuration (free-hanging in-line). Physical and electrical interchangeability is confirmed across all critical parameters.

Q: What are the key differences between these two parts?

A: The ET0902500000G provides enhanced electrical ratings (600 V vs. 300 V), extended operating temperature range (-40°C to 115°C vs. -33°C to 105°C), and is currently in active production. The OSTET090250 is obsolete. Both maintain identical mechanical specifications and regulatory compliance.

Q: Are there any compatibility concerns with wire gauge or termination?

A: No. Both components support identical wire gauge range (8-24 AWG) and screw torque specification (0.79 Nm / 7.0 Lb-In). Termination procedures and wire preparation requirements are equivalent.

Q: Does the substitute meet the same regulatory requirements?

A: Yes. The ET0902500000G maintains UL94 V-0 flammability rating and ROHS3 compliance, matching the original component's regulatory profile.

Q: What is the wire strip length requirement for the substitute?

A: The ET0902500000G requires 10-11mm wire strip length, compared to 7-8mm for the original OSTET090250. This difference must be observed during wire preparation to ensure proper screw termination and electrical contact.

Q: Is the substitute available in the same packaging format?

A: The ET0902500000G is supplied in bulk packaging, whereas the original OSTET090250 packaging specification was not provided. Verify packaging requirements for your procurement process.
