Substitute Part Grouping Explanation

The HM1490810000G from Amphenol Anytek qualifies as a direct substitute based on the following critical parameters:

Matching Parameters:

• 14 positions per level
• 0.295" (7.50mm) pitch spacing
• Vertical with board mating orientation
• 8A current rating
• 250V voltage rating
• 12-28 AWG wire gauge compatibility
• Screwless push-in spring wire termination
• Thermoplastic housing with brass contacts
• ROHS3 compliance
• MSL 1 (Unlimited) moisture sensitivity level

Functional Equivalence: Both parts provide identical electrical and mechanical interface specifications for wire-to-board connections, enabling direct substitution in applications requiring 14-position terminal blocks with 7.5mm pitch spacing.

Parameter Comparison

Engineering Selection Recommendations

The HM1490810000G is suitable for applications currently using the OSTHM149081. The substitute part maintains all critical electrical and mechanical specifications while offering an extended operating temperature range (-40°C to 115°C versus -30°C to 105°C) and improved contact plating with tin-plated brass. Both parts carry ROHS3 compliance and identical moisture sensitivity ratings, ensuring regulatory and environmental compatibility.

The HM1490810000G offers the additional advantage of active product status, ensuring continued availability and supply chain stability compared to the obsolete OSTHM149081.

Frequently Asked Questions (FAQ)

Q: Can HM1490810000G replace OSTHM149081 in existing designs? A: Yes. Both parts share identical electrical ratings (8A, 250V), wire gauge compatibility (12-28 AWG), pitch spacing (7.5mm), and wire termination methods. The substitute part is functionally equivalent for wire-to-board connection applications.

Q: What is the difference in mounting between these parts? A: The OSTHM149081 uses press-fit mounting only. The HM1490810000G supports both through-hole and press-fit mounting options, providing greater installation flexibility while maintaining press-fit compatibility with existing designs.

Q: Are there temperature range differences? A: The HM1490810000G operates across a wider temperature range (-40°C to 115°C) compared to the OSTHM149081 (-30°C to 105°C). This extended range provides additional margin for applications operating at temperature extremes.

Q: Do both parts meet the same compliance standards? A: Yes. Both parts are ROHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity ratings, ensuring equivalent regulatory and environmental compliance.

Q: What is the significance of tin plating on the HM1490810000G contacts? A: The tin plating on brass contacts in the HM1490810000G provides enhanced corrosion resistance compared to unplated brass in the OSTHM149081, potentially improving long-term reliability in corrosive environments.
