Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the OSTEO040100 is determined by strict alignment of the following critical parameters:

• 4-position configuration with 0.197" (5.00mm) pitch spacing
• Screw termination method
• Free-hanging in-line mounting orientation
• 300 V UL voltage rating
• 12-28 AWG wire gauge compatibility
• 0.51 Nm (4.5 Lb-In) screw torque specification
• Wire strip length of 5-6mm
• ROHS3 compliance

The substitute part EO0401000000G (Amphenol Anytek) meets all critical electrical and mechanical parameters required for functional equivalence. Variations in contact material, housing material, contact mating finish, and operating temperature range do not preclude substitution when the core functional parameters align.

Parameter Comparison

Engineering Selection Recommendations

The EO0401000000G qualifies as a direct functional substitute for the OSTEO040100 based on alignment of all critical electrical and mechanical parameters. Both components maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for equivalent component selection.

The substitute part offers extended operating temperature range (-40°C ~ 115°C versus -30°C ~ 105°C), providing additional thermal margin in applications approaching temperature extremes. The active product status of EO0401000000G ensures ongoing availability and supply chain continuity, addressing the procurement constraints associated with the obsolete OSTEO040100.

Frequently Asked Questions (FAQ)

Q: What makes EO0401000000G a valid substitute for OSTEO040100?

A: Both components share identical pitch (5.00mm), position count (4), termination method (screw), mounting configuration (free-hanging in-line), voltage rating (300 V UL), wire gauge range (12-28 AWG), screw torque (0.51 Nm), and wire strip length (5-6mm). These parameters define functional compatibility for unshrouded header applications.

Q: Are there differences in material composition between these parts?

A: Yes. OSTEO040100 uses brass contacts and housing with nickel mating finish. EO0401000000G uses phosphor bronze contacts with tin mating finish and thermoplastic housing. These material differences do not affect electrical or mechanical compatibility when the core functional parameters remain aligned.

Q: Does the extended temperature range of EO0401000000G affect substitution suitability?

A: No. The extended operating range (-40°C ~ 115°C) of EO0401000000G encompasses the original specification (-30°C ~ 105°C), providing equivalent or superior performance across the original operating envelope.

Q: Are both parts RoHS compliant?

A: Yes. Both OSTEO040100 and EO0401000000G are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component procurement.

Q: What is the packaging difference between these parts?

A: OSTEO040100 is supplied in standard packaging. EO0401000000G is supplied in bulk packaging. Packaging format does not affect component functionality or electrical characteristics.
