Key Parameters

Substitute Part Grouping Explanation

The 93J270E qualifies as a parametric equivalent based on matching all critical electrical and mechanical parameters: identical resistance value (270 Ohms), tolerance (±5%), power rating (3.25W), composition (wirewound), axial package configuration, temperature coefficient (±30ppm/°C), and physical dimensions (0.233" Dia x 0.579" L). The primary distinction between the main part and substitute is packaging format and RoHS compliance status. Both parts are manufactured by Ohmite within the 90 series and maintain the same safety features and flame retardant coating.

Parameter Comparison

Engineering Selection Recommendations

Both the 93J270 and 93J270E are Active products manufactured by Ohmite with complete electrical and mechanical equivalence. Selection between these parts depends on regulatory and procurement requirements:

The 93J270 is suitable for applications where RoHS compliance is not mandated and standard packaging is preferred. The 93J270E is the appropriate choice for designs requiring ROHS3 compliance or bulk packaging formats. Both parts deliver identical performance in circuit applications due to matching resistance, tolerance, power rating, temperature coefficient, and physical dimensions. Inventory availability is comparable for both variants, with 894 units of the main part and 856 units of the substitute currently in stock.

Frequently Asked Questions (FAQ)

Q: Can the 93J270E replace the 93J270 in existing designs? A: Yes. The 93J270E is electrically and mechanically equivalent, with identical resistance (270 Ohms), tolerance (±5%), power rating (3.25W), temperature coefficient (±30ppm/°C), and axial package dimensions (0.233" Dia x 0.579" L). Direct substitution is valid for circuit functionality.

Q: What is the difference between these two parts? A: The primary differences are packaging format (standard vs. bulk) and RoHS compliance status (non-compliant vs. ROHS3 compliant). All electrical and mechanical parameters are identical.

Q: Does RoHS compliance affect circuit performance? A: No. RoHS compliance relates to material composition and environmental regulations, not electrical performance. Both parts deliver identical circuit behavior.

Q: Are the physical dimensions identical? A: Yes. Both parts measure 0.233" diameter by 0.579" length (5.90mm x 14.70mm), ensuring identical PCB footprint and mounting compatibility.

Q: Which part should I specify for new designs? A: Specify the 93J270E for designs requiring ROHS3 compliance. Specify the 93J270 if RoHS compliance is not a requirement and standard packaging is preferred.

Q: Are both parts currently available? A: Yes. The 93J270 has 894 units in stock and the 93J270E has 856 units in stock.
