Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the OSTHM054081 is determined by the following critical parameters:

• Electrical Compatibility: Current rating (minimum 8A), voltage rating (minimum 250V), and wire gauge acceptance (12-28 AWG)
• Mechanical Compatibility: 5 positions per level, 0.300" (7.62mm) pitch spacing, vertical with board mating orientation
• Termination Compatibility: Screwless push-in spring wire termination method
• Environmental Compliance: ROHS3 compliance and operating temperature range support
• Mounting Method: Press-fit capability for PCB integration

The substitute part HM0540810000G from Amphenol Anytek meets all critical substitution criteria while offering enhanced electrical ratings and an active product status.

Parameter Comparison

Engineering Selection Recommendations

The HM0540810000G qualifies as a direct substitute for the OSTHM054081 based on matching electrical specifications, mechanical dimensions, and termination methods. The substitute part offers improved voltage rating (300V versus 250V) and extended operating temperature range (-40°C to 115°C versus -30°C to 105°C), providing enhanced performance margins. Both parts maintain ROHS3 compliance and support identical wire gauge specifications. The substitute part's active product status ensures long-term availability and supply chain continuity, addressing the obsolescence of the original component.

Frequently Asked Questions (FAQ)

Q: Can HM0540810000G be used as a direct replacement for OSTHM054081 in existing designs?

A: Yes. Both parts share identical pitch (0.300"), position count (5), mating orientation (vertical with board), current rating (8A), wire gauge range (12-28 AWG), and wire termination method (screwless push-in spring). The substitute part's higher voltage rating (300V) and extended temperature range provide additional design margin.

Q: What is the difference in mounting between these parts?

A: The OSTHM054081 uses press-fit mounting only. The HM0540810000G supports both through-hole and press-fit mounting options, providing greater PCB integration flexibility.

Q: Are there any compliance differences between the two parts?

A: Both parts are ROHS3 compliant and REACH unaffected. No compliance barriers exist for substitution.

Q: Does the tin plating on the HM0540810000G contacts affect compatibility?

A: No. Tin plating on brass contacts is a standard enhancement that improves corrosion resistance and contact reliability without affecting electrical or mechanical compatibility.

Q: What packaging is available for the substitute part?

A: The HM0540810000G is supplied in bulk packaging, with 876 pieces available in new original stock condition.
