OSTEO210100 Terminal Block Plug - Equivalent & Substitute Parts

Part Overview

The OSTEO210100 is a 21-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 support and procurement planning.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the OSTEO210100 is determined by strict alignment of the following critical parameters:

• Position Count & Pitch: 21 positions at 0.197" (5.00mm) spacing (non-negotiable for mechanical fit)
• Connector Type: Plug for unshrouded header (form factor requirement)
• Termination Method: Screw termination (electrical connection standard)
• Mounting Configuration: Free hanging in-line (installation constraint)
• Voltage Rating: 300 V UL minimum (electrical safety requirement)
• Wire Gauge Compatibility: 12-28 AWG (conductor accommodation)
• Screw Torque Specification: 0.51 Nm (4.5 Lb-In) (assembly standard)
• Wire Strip Length: 5-6mm (preparation specification)
• Regulatory Compliance: ROHS3 compliant (environmental requirement)

The substitute part EO210102A000G meets all critical parameters while offering enhanced operating temperature range and improved material specifications.

Parameter Comparison

Engineering Selection Recommendations

The EO210102A000G from Amphenol Anytek is the qualified substitute for the obsolete OSTEO210100. Selection is based on:

• Functional Equivalence: All critical mechanical and electrical parameters align with the original specification
• Active Production Status: The substitute is currently in active production with confirmed inventory availability (808 pcs)
• Regulatory Compliance: Both parts maintain ROHS3 compliance and REACH unaffected status
• Enhanced Operating Range: The substitute supports -40°C to 115°C, exceeding the original -30°C to 105°C specification
• Identical Assembly Standards: Screw torque specification (0.51 Nm) and wire preparation (5-6mm strip length) remain unchanged

Frequently Asked Questions (FAQ)

Q: Can EO210102A000G be used as a direct replacement for OSTEO210100?

A: Yes. Both parts share identical position count (21), pitch spacing (5.00mm), termination method (screw), mounting configuration (free hanging in-line), voltage rating (300 V), wire gauge range (12-28 AWG), and assembly torque specification (0.51 Nm). The substitute meets all functional requirements for direct substitution.

Q: What are the key differences between these parts?

A: The EO210102A000G offers an extended operating temperature range (-40°C to 115°C versus -30°C to 105°C), improved contact material (phosphor bronze versus brass), thermoplastic housing (versus brass), tin contact mating finish (versus nickel), and active production status. These represent enhancements rather than deviations from the original specification.

Q: Are there any compatibility concerns with existing installations?

A: No compatibility concerns exist. The substitute maintains identical mechanical form factor, electrical ratings, and assembly specifications. The enhanced temperature range and material improvements provide equivalent or superior performance in all operating conditions.

Q: What is the packaging format for the substitute part?

A: The EO210102A000G is supplied in bulk packaging, compared to the original part's unspecified packaging format.

Q: Are both parts compliant with current environmental regulations?

A: Yes. Both the OSTEO210100 and EO210102A000G are ROHS3 compliant and REACH unaffected, meeting current environmental standards.
