The identified substitute part maintains all electrical and mechanical specifications. Variations in packaging format (Bulk vs. standard) and compliance certifications do not affect functional equivalence for component selection purposes.

Parameter Comparison

Engineering Selection Recommendations

The Ohmite 20J2K2E serves as a direct parametric equivalent to the 20J2K2. Both components are Active status products from the same manufacturer and series, with identical electrical and mechanical specifications.

Selection between these parts is determined by compliance and packaging requirements:

• 20J2K2: Use when RoHS non-compliant components are acceptable for the application.
• 20J2K2E: Use when RoHS compliance is required. This variant also provides improved moisture sensitivity classification (MSL 1 - Unlimited) compared to the original part.

Both parts are suitable for identical circuit applications and board layouts due to matching dimensions and termination configuration.

Frequently Asked Questions (FAQ)

Q: Can 20J2K2E replace 20J2K2 in existing designs?

A: Yes. The 20J2K2E is a parametric equivalent with identical resistance, tolerance, power rating, composition, package type, and physical dimensions. The primary difference is RoHS compliance status and moisture sensitivity rating.

Q: What is the difference between standard and Bulk packaging?

A: Packaging format does not affect component functionality or electrical performance. Standard and Bulk packaging refer to order quantity and container type. Component specifications remain identical.

Q: Are there any thermal or frequency limitations for these parts?

A: Both parts operate within the specified temperature coefficient of ±30ppm/°C. No additional operating temperature range or frequency limitations are provided in the component specifications.

Q: Which part should be selected for new designs?

A: For new designs, the 20J2K2E is recommended due to RoHS compliance status and superior moisture sensitivity classification, unless specific design constraints require the non-compliant variant.

Q: Are these parts interchangeable on the PCB?

A: Yes. Both parts share identical axial package dimensions (0.394" Dia x 1.858" L) and two-terminal configuration, ensuring direct board-level compatibility.
