Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the OSTHM083080 is determined by strict equivalence across the following critical parameters:

• Electrical Compatibility: Identical current (8A) and voltage (300V) ratings
• Mechanical Compatibility: Matching pitch (0.150"/3.81mm), position count (8), and through-hole mounting configuration
• Termination Method: Screwless push-in spring termination with identical wire gauge acceptance (14-28 AWG)
• Physical Form Factor: Vertical with board orientation and thermoplastic housing
• Regulatory Compliance: RoHS3 compliance and REACH unaffected status

The substitute part HM0830800000G by Amphenol Anytek meets all these criteria, with enhanced operating temperature range and active product status.

Parameter Comparison

Engineering Selection Recommendations

The HM0830800000G is a direct functional equivalent to the OSTHM083080 for all electrical and mechanical applications. Selection of this substitute is supported by:

• Product Status: The substitute maintains active production status, ensuring long-term availability and supply chain continuity
• Regulatory Compliance: Both parts maintain identical RoHS3 and REACH compliance certifications
• Enhanced Operating Range: The substitute provides extended temperature operation (-40°C to 115°C versus -30°C to 105°C), offering improved performance margin in thermal extremes
• Contact Plating Enhancement: Tin plating on the substitute's brass contacts provides improved corrosion resistance compared to unplated brass

No design modifications or PCB layout changes are required for substitution. Direct pin-for-pin replacement is applicable.

Frequently Asked Questions (FAQ)

Q: Can HM0830800000G be used as a direct replacement for OSTHM083080 without PCB modifications?

A: Yes. Both parts share identical pitch (3.81mm), position count (8), mounting type (through hole), and termination method (screwless push-in spring). No PCB layout changes are necessary.

Q: What is the significance of the tin plating on the HM0830800000G contacts?

A: Tin plating enhances corrosion resistance of the brass contacts, extending component life in humid or corrosive environments. This is a material improvement over unplated brass and does not affect electrical performance or compatibility.

Q: Are there any electrical performance differences between these parts?

A: No. Both parts maintain identical current (8A), voltage (300V), and wire gauge (14-28 AWG) specifications. Electrical performance is equivalent.

Q: Why is the OSTHM083080 listed as obsolete?

A: Obsolescence indicates the part is no longer manufactured by On Shore Technology Inc. The HM0830800000G substitute ensures continued availability for applications requiring this terminal block configuration.

Q: Does the extended operating temperature range of HM0830800000G affect compatibility?

A: No. The extended range (-40°C to 115°C versus -30°C to 105°C) represents an improvement that maintains full backward compatibility. Applications operating within the original temperature range experience no change in performance.

Q: Are both parts compliant with current regulatory requirements?

A: Yes. Both the OSTHM083080 and HM0830800000G maintain RoHS3 compliance and REACH unaffected status, meeting current regulatory standards for electronic components.
