OSTET110252 Terminal Block Plug - Equivalent & Substitute Parts

Part Overview

The OSTET110252 is an 11-position terminal block plug with female sockets, 0.300" (7.62mm) pitch, designed for free-hanging in-line applications. Manufactured by On Shore Technology Inc., this component features screw termination and operates across -33°C to 105°C. The product is currently obsolete, making equivalent substitutes necessary for ongoing system maintenance and new designs requiring compatible connectivity solutions.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the OSTET110252 is determined by the following critical parameters:

• Position Count & Pitch: Both substitute parts maintain 11 positions at 0.300" (7.62mm) pitch, ensuring mechanical and electrical compatibility with mating connectors designed for the original part.
• Mounting Configuration: Free-hanging in-line mounting is preserved across all substitutes.
• Termination Method: Screw-based termination is maintained, allowing integration with existing wire harnesses and assembly procedures.
• Wire Gauge Compatibility: All substitutes accept 8-24 AWG wire, matching the original specification.
• Voltage & Temperature Ratings: Substitute parts meet or exceed the original electrical and thermal requirements.
• Compliance Standards: All parts maintain UL94 V-0 flammability rating and ROHS3 compliance.

The two substitute parts differ in contact type (female sockets vs. blade sockets) and wire entry orientation, requiring verification of mating connector compatibility before selection.

Parameter Comparison

Engineering Selection Recommendations

ET1102520000G is the direct functional equivalent to OSTET110252. Both parts feature female socket contacts and identical pitch, position count, and wire gauge specifications. ET1102520000G is currently in active production status with higher inventory availability (1010 pcs vs. 928 pcs). The substitute provides enhanced voltage rating (600 V vs. 300 V) and extended operating temperature range (-40°C to 115°C vs. -33°C to 105°C). Wire entry orientation differs at 180°, requiring confirmation that mating connectors accommodate this configuration. All compliance certifications (ROHS3, REACH Unaffected, UL94 V-0) are maintained.

ET1101520000G is an alternative substitute with blade socket contacts instead of female sockets. This part is suitable only if the mating connector system uses blade-type pins. The rising cage clamp termination method differs from the original screw termination, potentially affecting assembly procedures. This substitute also maintains full compliance and offers equivalent thermal and voltage performance.

Selection between ET1102520000G and ET1101520000G depends entirely on mating connector socket type compatibility. ET1102520000G is recommended as the primary substitute due to matching contact geometry with the original part.

Frequently Asked Questions (FAQ)

Q: Can ET1102520000G directly replace OSTET110252 in existing assemblies?

A: ET1102520000G maintains identical position count (11), pitch (0.300"), wire gauge range (8-24 AWG), and screw termination method. The primary consideration is wire entry orientation: ET1102520000G features 180° wire entry versus the original part's straight entry. Verify that your mating connector and harness routing accommodate this orientation change before implementation.

Q: What is the difference between ET1102520000G and ET1101520000G?

A: ET1102520000G uses female socket contacts matching the original OSTET110252 design. ET1101520000G uses blade socket contacts and rising cage clamp termination. Selection depends on your mating connector type. If your system uses female pin connectors, select ET1102520000G. If your system uses blade pin connectors, select ET1101520000G.

Q: Are all substitute parts RoHS and REACH compliant?

A: Yes. Both ET1102520000G and ET1101520000G are ROHS3 compliant and REACH unaffected, matching the original OSTET110252 specifications.

Q: Does the higher voltage rating of ET1102520000G (600 V vs. 300 V) affect compatibility?

A: No. Higher voltage rating indicates enhanced electrical capability and does not affect mechanical or electrical compatibility with systems designed for 300 V operation. This represents an improvement in component robustness.

Q: What is the inventory status of these substitutes?

A: ET1102520000G has 1010 pcs in stock (active production). ET1101520000G has 1168 pcs in stock (active production). Both substitutes offer significantly better long-term availability compared to the obsolete OSTET110252.

Q: Are the screw torque specifications identical?

A: Yes. All three parts specify 0.79 Nm (7.0 Lb-In) screw torque, ensuring consistent assembly procedures across the original and substitute components.
