Substitute Part Grouping Explanation

The HM0740800000G manufactured by Amphenol Anytek qualifies as a direct substitute based on matching critical electrical and mechanical parameters: identical 7-position configuration, 0.300" (7.62mm) pitch, vertical board mounting orientation, through-hole installation, screwless push-in spring termination, and compatible wire gauge range (12-28 AWG). Both parts maintain identical physical footprints and functional interfaces.

Substitution is valid across the following key parameters:

• Positions Per Level: 7 (identical)
• Pitch: 0.300" (7.62mm) (identical)
• Mating Orientation: Vertical with Board (identical)
• Wire Gauge: 12-28 AWG (identical)
• Mounting Type: Through Hole (identical)
• Wire Termination: Screwless - Leg Spring, Push-In Spring (identical)
• Housing Material: Thermoplastic (identical)
• Features: Interlocking (Side) (identical)

Parameter Comparison

Engineering Selection Recommendations

The HM0740800000G is the direct functional equivalent for OSTHM074080 applications. The substitute part carries active product status from Amphenol Anytek, ensuring ongoing availability and supply chain continuity. Both components maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for equivalent applications.

The HM0740800000G provides enhanced electrical performance with a 300 V voltage rating compared to the 250 V rating of the original part, and extends the operating temperature range to -40°C ~ 115°C versus -30°C ~ 105°C. The tin-plated brass contact material in the substitute part offers improved corrosion resistance compared to unplated brass. These enhancements represent performance improvements suitable for direct substitution without circuit redesign.

Frequently Asked Questions (FAQ)

Q: Can HM0740800000G replace OSTHM074080 in existing designs? A: Yes. Both parts share identical mechanical footprints, pitch spacing, position count, and electrical interface specifications. Direct PCB substitution is valid without layout modifications.

Q: Are there voltage rating differences between these parts? A: The HM0740800000G is rated for 300 V compared to the OSTHM074080 at 250 V. This represents a performance enhancement and does not restrict substitution in applications rated at or below 250 V.

Q: Do the operating temperature ranges differ? A: The HM0740800000G operates across -40°C ~ 115°C versus -30°C ~ 105°C for the OSTHM074080. The substitute part provides extended temperature capability suitable for wider environmental applications.

Q: What is the difference in contact plating? A: The OSTHM074080 uses unplated brass contacts, while the HM0740800000G features tin-plated brass. Tin plating provides enhanced corrosion resistance and is compatible with standard PCB assembly processes.

Q: Are both parts RoHS and REACH compliant? A: Yes. Both the OSTHM074080 and HM0740800000G are ROHS3 compliant and REACH unaffected, meeting regulatory requirements for equivalent component selection.

Q: What wire gauges are supported? A: Both parts accommodate wire gauges from 12-28 AWG with identical push-in spring termination mechanisms.
