Substitute Part Grouping Explanation

The ED3100/2 qualifies as a direct substitute for the OSTHH020080 based on the following critical parameters:

• Electrical Compatibility: Both parts maintain 300V voltage rating and support 14-28 AWG wire gauges. The ED3100/2 provides 16A current capacity, which exceeds the 15A requirement of the original part.
• Mechanical Compatibility: Identical 2-position configuration with 5.00mm pitch and horizontal board-mounted orientation ensure PCB layout compatibility without redesign.
• Termination Method: Both employ screwless push-in spring termination, maintaining identical wire connection procedures.
• Environmental Specifications: Matching -30°C to 105°C operating temperature range and identical MSL rating (1 - Unlimited) confirm thermal and moisture performance equivalence.
• Regulatory Compliance: Both parts are ROHS3 compliant and REACH unaffected, satisfying identical compliance requirements.

Parameter Comparison

Engineering Selection Recommendations

The ED3100/2 is the qualified substitute for the obsolete OSTHH020080. Selection is based on:

• Product Status: The ED3100/2 maintains active production status, ensuring long-term availability and supply chain continuity.
• Regulatory Alignment: Both parts satisfy identical ROHS3 and REACH compliance requirements, eliminating regulatory risk in substitution.
• Performance Margin: The ED3100/2 current rating of 16A exceeds the original 15A specification, providing operational headroom without design modification.
• Functional Equivalence: Identical electrical, mechanical, and termination specifications confirm direct interchangeability at the PCB assembly level.

Frequently Asked Questions (FAQ)

Q: Can ED3100/2 be used as a direct replacement for OSTHH020080 without PCB redesign?

A: Yes. Both parts share identical pitch (5.00mm), position count (2), mounting type (through hole), and mating orientation (horizontal with board). No PCB layout modification is required.

Q: Are there any current rating differences that affect circuit design?

A: The ED3100/2 provides 16A capacity versus the original 15A rating. This represents a 6.7% increase and does not require design changes for circuits operating within the original 15A specification.

Q: Do both parts support the same wire gauge range?

A: Yes. Both OSTHH020080 and ED3100/2 accept 14-28 AWG wire, maintaining identical wire termination compatibility.

Q: What is the difference in housing material between these parts?

A: OSTHH020080 uses thermoplastic housing, while ED3100/2 uses polyamide (PA) or nylon. Both materials meet the same operating temperature range (-30°C to 105°C) and environmental specifications.

Q: Are compliance certifications identical?

A: Yes. Both parts are ROHS3 compliant, REACH unaffected, and carry identical MSL rating (1 - Unlimited), satisfying all regulatory and environmental requirements.

Q: What packaging is available for ED3100/2?

A: ED3100/2 is supplied in bulk packaging, with 905 pieces currently in stock as new original inventory.
