Substitute Part Grouping Explanation

Substitute parts for the Ohmite 20J100 are identified based on strict parametric equivalence. The following criteria determine substitutability:

• Resistance value: 100 Ohms
• Tolerance: ±5%
• Power rating: 10W
• Composition: Wirewound
• Package: Axial
• Physical dimensions: 0.394" Dia x 1.858" L (10.00mm x 47.20mm)
• Temperature coefficient: ±30ppm/°C
• Features: Flame retardant coating and safety characteristics

The identified substitute, Ohmite 20J100E, matches all critical electrical and mechanical parameters. Differences in regulatory compliance (RoHS status and REACH classification) are noted but do not affect electrical or mechanical interchangeability.

Parameter Comparison

Engineering Selection Recommendations

Both the Ohmite 20J100 and 20J100E are active production parts from the same manufacturer with identical electrical and mechanical specifications. Selection between these parts should be based on regulatory compliance requirements:

• The 20J100E is RoHS Compliant and carries MSL 1 (Unlimited) rating, making it suitable for applications subject to RoHS directives or requiring enhanced moisture handling documentation.
• The 20J100 is RoHS non-compliant and carries no MSL specification, suitable for applications without RoHS requirements.

Both parts are classified as EAR99 for export control purposes. Inventory availability: 20J100 (733 units), 20J100E (964 units).

Frequently Asked Questions (FAQ)

Q: Are the 20J100 and 20J100E electrically identical?

A: Yes. Both parts have identical resistance (100 Ohms), tolerance (±5%), power rating (10W), temperature coefficient (±30ppm/°C), and wirewound composition. They are direct electrical equivalents.

Q: Can I substitute 20J100E for 20J100 in my design?

A: Yes, from an electrical and mechanical standpoint. The 20J100E is a direct parametric equivalent with identical package dimensions (0.394" Dia x 1.858" L) and axial termination configuration. Verify compliance requirements for your application, as the 20J100E is RoHS Compliant while the 20J100 is not.

Q: What is the difference in RoHS compliance between these parts?

A: The 20J100E meets RoHS Directive requirements, while the 20J100 does not. If your application or market requires RoHS compliance, use the 20J100E. Both parts are otherwise equivalent.

Q: Are the physical dimensions identical?

A: Yes. Both parts measure 0.394" diameter by 1.858" length (10.00mm x 47.20mm) and use axial packaging with 2 terminations.

Q: Which part should I choose for new designs?

A: For new designs, the 20J100E is recommended due to its RoHS Compliant status and defined MSL rating (1 - Unlimited), providing better regulatory alignment and moisture handling documentation. Both parts are active and in stock.
