OSTEO240100 Terminal Block Plug - Equivalent & Substitute Parts

Part Overview

The OSTEO240100 is a 24-position terminal block plug designed for unshrouded headers with 0.197" (5.00mm) pitch spacing. This component features screw termination, free-hanging in-line mounting, and operates across -30°C to 105°C. The part is currently obsolete, making identification of functionally equivalent alternatives essential for ongoing system maintenance and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the OSTEO240100 is determined by strict alignment with the following critical parameters:

• Position Count & Pitch: 24 positions at 0.197" (5.00mm) spacing (non-negotiable for mechanical fit)
• Connector Type: Plug for unshrouded header with free-hanging in-line mounting
• Termination Method: Screw-based wire termination
• Electrical Ratings: 300 V UL voltage rating minimum; wire gauge compatibility 12-28 AWG
• Operating Temperature Range: Minimum -30°C to 105°C coverage
• Screw Torque Specification: 0.51 Nm (4.5 Lb-In)
• Compliance: ROHS3 compliance required

The EO240102A000G meets all substitution criteria while offering enhanced specifications in contact material, housing durability, and extended temperature range.

Engineering Selection Recommendations

The EO240102A000G from Amphenol Anytek is the qualified substitute for the obsolete OSTEO240100. Selection is based on:

• Mechanical Compatibility: Identical 24-position, 5.00mm pitch configuration ensures direct fit with existing unshrouded header connectors
• Electrical Equivalence: Matching 300 V UL rating, 12-28 AWG wire gauge support, and 0.51 Nm screw torque specification
• Regulatory Compliance: Both parts maintain ROHS3 compliance and REACH unaffected status
• Active Manufacturing Status: EO240102A000G is currently in active production with confirmed inventory availability (695 pcs), eliminating supply chain risk associated with the obsolete OSTEO240100
• Enhanced Operating Range: The substitute provides extended temperature coverage (-40°C to 115°C) compared to the original (-30°C to 105°C), offering improved performance margin in thermal extremes

Frequently Asked Questions (FAQ)

Q: Can the EO240102A000G be used as a direct replacement for OSTEO240100 in existing assemblies?

A: Yes. Both parts share identical mechanical pitch (5.00mm), position count (24), mounting configuration (free-hanging in-line), and screw termination specifications. The substitute meets or exceeds all electrical and thermal requirements of the original.

Q: What are the key differences between these parts?

A: The EO240102A000G features phosphor bronze contacts versus brass in the original, thermoplastic housing versus brass, tin contact mating finish versus nickel, and an extended operating temperature range (-40°C to 115°C versus -30°C to 105°C). These represent material and performance enhancements rather than functional changes.

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

A: No. Both parts support identical wire gauge ranges (12-28 AWG) and require the same screw torque specification (0.51 Nm / 4.5 Lb-In). Installation procedures remain unchanged.

Q: Why is the OSTEO240100 listed as obsolete?

A: Obsolescence indicates the part is no longer manufactured by On Shore Technology Inc. The EO240102A000G provides functional equivalence with active manufacturing support and improved specifications.

Q: Does the substitute meet the same compliance standards?

A: Yes. The EO240102A000G maintains ROHS3 compliance and REACH unaffected status, matching the regulatory profile of the original OSTEO240100.
