Substitute Part Grouping Explanation

Substitution eligibility for the OSTH3210080 is determined by the following critical parameters:

Position Count & Pitch: 21 positions at 0.197" (5.00mm) spacing
Mating Orientation: Angled configuration
Electrical Ratings: Minimum 10 A current, 300 V voltage
Wire Termination Method: Screwless push-in spring mechanism
Mounting Configuration: Through-hole PCB mounting
Wire Gauge Compatibility: 12-28 AWG acceptance range
Environmental Compliance: ROHS3 and REACH status

The OSTHG210080 qualifies as a direct substitute based on matching all critical parameters. This part maintains identical position count, pitch, orientation, wire termination method, and environmental compliance. The substitute exhibits enhanced current rating (15 A versus 10 A), representing a performance upgrade within the same mechanical and electrical envelope. The OSTHG series represents the active product line continuation from the obsolete OSTH3 series.

Engineering Selection Recommendations

The OSTHG210080 is the appropriate substitute for the obsolete OSTH3210080 based on the following factors:

Product Status & Availability: The OSTHG210080 maintains active product status with current manufacturing and distribution support, ensuring long-term procurement viability and supply chain continuity.

Regulatory Compliance: Both components maintain identical ROHS3 and REACH compliance certifications, satisfying environmental and hazardous substance requirements without modification to existing design documentation.

Electrical Performance: The substitute provides enhanced current rating (15 A) while maintaining all other electrical specifications. This upgrade does not introduce incompatibility and provides additional design margin for applications operating at or near the original 10 A specification.

Mechanical Compatibility: Identical pitch, position count, orientation, and mounting configuration ensure direct PCB footprint compatibility without layout modification.

Wire Termination Consistency: Both components employ identical screwless push-in spring termination methodology, maintaining assembly process compatibility and operator familiarity.

Frequently Asked Questions (FAQ)

Q: Can the OSTHG210080 be used as a direct replacement for OSTH3210080 without PCB redesign?

A: Yes. The OSTHG210080 maintains identical pitch (5.00mm), position count (21), mating orientation (angled), and mounting configuration (through-hole). PCB footprint compatibility is preserved without modification.

Q: What is the primary difference between these two parts?

A: The OSTHG210080 provides increased current rating (15 A versus 10 A). The OSTH3 series is obsolete; the OSTHG series represents the active product line continuation from On Shore Technology Inc.

Q: Are there any compliance or certification differences?

A: No. Both components maintain identical ROHS3 and REACH compliance status, requiring no changes to regulatory documentation or certification records.

Q: Does the higher current rating of the substitute create any compatibility issues?

A: No. The enhanced current rating represents a performance upgrade within the same mechanical and electrical envelope. Applications designed for 10 A operation remain fully compatible.

Q: What wire gauge range is supported by both components?

A: Both the OSTH3210080 and OSTHG210080 accept wire gauges from 12 to 28 AWG, maintaining identical wire termination compatibility.

Q: Are the operating temperature ranges identical?

A: Yes. Both components operate across the -30°C to 105°C temperature range with identical thermal performance characteristics.
