Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the OSTHM044080 is determined by strict equivalence across the following critical parameters:

• Electrical Compatibility: Positions per level (4), pitch spacing (0.300"/7.62mm), current rating (8 A minimum), voltage rating (250 V minimum), and wire gauge acceptance (12-28 AWG)
• Mechanical Compatibility: Vertical with board mating orientation, through-hole mounting, push-in spring termination method, and thermoplastic housing
• Environmental Compliance: RoHS3 compliance and MSL rating of 1 (Unlimited)

The substitute part HM0440800000G meets all these criteria while offering enhanced specifications in voltage rating (300 V) and operating temperature range (-40°C ~ 115°C), with active product status ensuring continued availability.

Parameter Comparison

Engineering Selection Recommendations

The HM0440800000G from Amphenol Anytek is a direct functional equivalent to the obsolete OSTHM044080. Both components maintain identical electrical and mechanical specifications across all critical parameters: 4-position configuration, 7.62mm pitch, 8 A current capacity, 12-28 AWG wire gauge compatibility, and push-in spring termination.

The HM0440800000G offers superior specifications in voltage rating (300 V versus 250 V) and extended operating temperature range (-40°C to 115°C versus -30°C to 105°C), providing enhanced margin for demanding applications. Both parts maintain ROHS3 compliance and unlimited moisture sensitivity rating, ensuring regulatory alignment.

The active product status of HM0440800000G ensures long-term procurement availability and supply chain stability, addressing the obsolescence risk of the original OSTHM044080.

Frequently Asked Questions (FAQ)

Q: Can HM0440800000G be used as a direct replacement for OSTHM044080 in existing designs?

A: Yes. Both components share identical pitch spacing (7.62mm), position count (4), mounting method (through-hole vertical), and wire termination approach (push-in spring). PCB footprints and wire gauge compatibility are equivalent.

Q: What is the significance of the voltage rating difference (250 V vs. 300 V)?

A: The HM0440800000G operates at a higher voltage ceiling. Applications designed for 250 V operation remain fully compatible. The higher rating provides additional safety margin in circuits approaching the original 250 V specification.

Q: Does the tin plating on HM0440800000G contacts affect compatibility?

A: No. Tin plating on brass contacts is a standard enhancement that improves corrosion resistance and contact reliability. It does not affect electrical or mechanical compatibility with existing wire terminations or PCB designs.

Q: Are there packaging differences between these parts?

A: OSTHM044080 packaging information is not specified in available data. HM0440800000G is supplied in bulk packaging. Confirm packaging requirements with your procurement specification.

Q: Do both parts meet the same regulatory standards?

A: Yes. Both OSTHM044080 and HM0440800000G are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with identical HTSUS coding (8536.90.4000).
