Ohmite 42J2K2 Equivalent & Substitute Parts

Part Overview

The Ohmite 42J2K2 is a 2.2 kOhms ±5% 2W through-hole resistor with axial wirewound composition, part of the Ohmicone® 40 series. This component is currently active in production and maintains 812 pieces in new original stock. The 42J2K2 is classified as RoHS non-compliant, which may necessitate identification of compliant alternatives for applications subject to RoHS regulations or procurement policies requiring RoHS3 compliance.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Ohmite 42J2K2 is determined by strict equivalence across the following parameters:

• Resistance value: 2.2 kOhms
• Tolerance: ±5%
• Power rating: 2W
• Composition: Wirewound
• Temperature coefficient: ±20ppm/°C
• Package type: Axial
• Physical dimensions: 0.220" Dia x 0.406" L (5.60mm x 10.30mm)
• Termination count: 2

The substitute part 42J2K2E maintains identical electrical and mechanical specifications. The primary distinction is packaging format (Bulk versus standard packaging) and RoHS compliance status (ROHS3 Compliant versus RoHS non-compliant).

Parameter Comparison

Engineering Selection Recommendations

The 42J2K2E serves as a direct parametric equivalent to the 42J2K2, with identical electrical performance and mechanical compatibility. Selection between these parts should be based on regulatory and procurement requirements:

• For applications requiring RoHS3 compliance, the 42J2K2E is the appropriate selection.
• For applications without RoHS compliance mandates, either part is electrically and mechanically interchangeable.
• Packaging format (Bulk for 42J2K2E versus standard for 42J2K2) may influence procurement workflows and inventory management practices.
• Both parts maintain active production status and adequate stock availability.

Frequently Asked Questions (FAQ)

Q: Are the 42J2K2 and 42J2K2E electrically identical?

A: Yes. Both parts share identical resistance (2.2 kOhms), tolerance (±5%), power rating (2W), temperature coefficient (±20ppm/°C), and composition (wirewound). Electrical performance is equivalent.

Q: Can the 42J2K2E be used as a direct replacement for the 42J2K2 in existing designs?

A: Yes. The parts are mechanically and electrically interchangeable. Both feature identical axial package dimensions (0.220" Dia x 0.406" L) and two terminations, allowing direct substitution on printed circuit boards without layout modifications.

Q: What is the primary difference between these parts?

A: The 42J2K2E is ROHS3 compliant, while the 42J2K2 is RoHS non-compliant. Additionally, the 42J2K2E is supplied in Bulk packaging format. All other specifications are identical.

Q: Which part should be selected for new designs?

A: For new designs subject to RoHS regulations or corporate procurement policies requiring RoHS compliance, the 42J2K2E is the appropriate selection. Both parts are in active production with adequate inventory.

Q: Does packaging format affect component performance?

A: No. Packaging format (Bulk versus standard) affects only procurement and handling procedures, not electrical or mechanical performance. The component itself is identical.
