Substitute Part Grouping Explanation

The 91J100E is identified as a parametric equivalent to the 91J100 based on the following criteria:

Electrical Parameters (Identical):

• Resistance: 100 Ohms
• Tolerance: ±5%
• Power Rating: 1.5W
• Temperature Coefficient: ±30ppm/°C
• Composition: Wirewound

Mechanical Parameters (Identical):

• Package Type: Axial
• Size / Dimension: 0.142" Dia x 0.453" L (3.60mm x 11.50mm)
• Number of Terminations: 2

Functional Features (Identical):

• Flame Retardant Coating
• Safety Construction

Differentiation: The primary distinction between these parts is packaging format (Box vs. Bulk) and RoHS compliance status. Both components maintain identical electrical performance and physical dimensions, making them functionally interchangeable in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

Selection between the 91J100 and 91J100E should be based on the following criteria:

Choose 91J100 (Box Packaging) when:

• Standard packaging format is required for inventory management
• RoHS non-compliant applications are acceptable

Choose 91J100E (Bulk Packaging) when:

• ROHS3 compliance is mandated by design specifications or regulatory requirements
• Bulk packaging format aligns with procurement and assembly processes
• Higher inventory availability is beneficial (839 Pcs vs. 740 Pcs)

Both parts deliver identical electrical performance and mechanical fit. The substitution is valid for all circuit applications where the 91J100 is specified, provided packaging and compliance requirements are satisfied.

Frequently Asked Questions (FAQ)

Q: Are the 91J100 and 91J100E electrically identical? A: Yes. Both components have identical resistance (100 Ohms), tolerance (±5%), power rating (1.5W), temperature coefficient (±30ppm/°C), and wirewound composition. They perform identically in circuit applications.

Q: Can I use 91J100E as a direct replacement for 91J100? A: Yes, provided your application accepts ROHS3 compliance. The physical dimensions, electrical specifications, and mechanical terminations are identical, ensuring direct substitution in through-hole circuit designs.

Q: What is the difference between Box and Bulk packaging? A: Box packaging (91J100) is standard retail/small-quantity format. Bulk packaging (91J100E) is used for high-volume procurement and assembly operations. The component itself is identical.

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

Q: Are the physical dimensions identical? A: Yes. Both parts measure 0.142" Dia x 0.453" L (3.60mm x 11.50mm) and use identical axial lead terminations, ensuring identical PCB footprint and mounting compatibility.

Q: Which part should I specify for new designs? A: Specify 91J100E if ROHS3 compliance is required. Specify 91J100 if RoHS non-compliant applications are acceptable. Both are Active status products suitable for production use.
