B12J200 Equivalent & Substitute Parts Reference

Part Overview

The B12J200 is a 200 Ohm, 12W axial wirewound resistor manufactured by Ohmite as part of the Brown Devil® 200 series. This through-hole component features flame retardant coating and safety construction, designed for applications requiring high power dissipation in a compact axial package. The part is currently active in production with 1125 units in stock. Substitute parts are identified to address packaging variations and RoHS compliance requirements for different procurement and application scenarios.

Substitute Part Grouping Explanation

Substitution between B12J200 and B12J200E is based on electrical and mechanical parameter equivalence. Both parts maintain identical specifications across all critical selection criteria: resistance value (200 Ohms), tolerance (±5%), power rating (12W), composition (wirewound), package configuration (axial), physical dimensions (0.313" Dia x 1.750" L), temperature coefficient (±260ppm/°C), and termination count (2). The primary distinction between these parts is packaging format and RoHS compliance status. B12J200 is supplied in standard packaging and is RoHS non-compliant, while B12J200E is supplied in bulk packaging and meets ROHS3 compliance requirements. Both parts are active products from Ohmite within the Brown Devil® 200 series.

Parameter Comparison

Engineering Selection Recommendations

Selection between B12J200 and B12J200E depends on regulatory and procurement requirements. Choose B12J200 for applications without RoHS compliance mandates or when standard packaging is specified. Select B12J200E when ROHS3 compliance is required or when bulk packaging aligns with procurement workflows. Both parts are active products with confirmed inventory availability. Electrical and mechanical performance are identical across all specified parameters, ensuring direct interchangeability in circuit applications where the packaging and compliance distinction is not a constraint.

Frequently Asked Questions (FAQ)

Q: Are B12J200 and B12J200E electrically identical? A: Yes. Both parts have identical resistance (200 Ohms), tolerance (±5%), power rating (12W), temperature coefficient (±260ppm/°C), and all other electrical specifications.

Q: What is the difference between B12J200 and B12J200E? A: The primary differences are packaging format (standard vs. bulk) and RoHS compliance status (non-compliant vs. ROHS3 compliant). Physical dimensions and electrical performance remain identical.

Q: Can B12J200E replace B12J200 in existing designs? A: Yes, provided that RoHS3 compliance does not conflict with design requirements. The axial package, physical dimensions, and electrical characteristics are equivalent.

Q: Can B12J200 replace B12J200E in existing designs? A: B12J200 can replace B12J200E only in applications where RoHS compliance is not mandated. Electrical and mechanical compatibility are confirmed.

Q: What does the axial package configuration mean? A: Axial package indicates that both terminations are located on opposite ends of the resistor body along the same axis, suitable for through-hole PCB mounting in linear component layouts.

Q: Are both parts suitable for high-temperature applications? A: Both parts operate with a temperature coefficient of ±260ppm/°C. Specific operating temperature limits are not provided in the available specifications.
