Key Parameters

Substitute Part Grouping Explanation

The 90J43RE qualifies as a parametric equivalent to the 90J43R based on the following critical parameters:

• Resistance value: 43 Ohms (identical)
• Tolerance: ±5% (identical)
• Power rating: 11W (identical)
• Composition: Wirewound (identical)
• Package type: Axial (identical)
• Temperature coefficient: ±30ppm/°C (identical)
• Physical dimensions: 0.343" Dia x 1.811" L (identical)
• Termination count: 2 (identical)
• Manufacturer: Ohmite (same manufacturer)
• Series: 90 (same series)

The primary difference between these parts is packaging format: the 90J43R is supplied in Box packaging, while the 90J43RE is supplied in Bulk packaging. Both parts maintain identical electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

The 90J43RE serves as a direct parametric substitute for the 90J43R. Selection between these parts should be based on the following factors:

Compliance Requirements: The 90J43RE is ROHS3 compliant, while the 90J43R is RoHS non-compliant. Applications subject to RoHS regulations must use the 90J43RE.

Packaging Needs: The 90J43R is supplied in Box packaging, suitable for smaller quantity orders or applications requiring individual unit packaging. The 90J43RE is supplied in Bulk packaging, appropriate for high-volume production runs or automated assembly processes.

Inventory Availability: The 90J43RE has higher stock availability (1110 units) compared to the 90J43R (649 units), making it preferable for time-sensitive procurement.

Both parts are manufactured by Ohmite within the same 90 series and maintain identical electrical performance characteristics for 43 Ohm, 11W wirewound axial resistor applications.

Frequently Asked Questions (FAQ)

Q: Can the 90J43RE be used as a direct replacement for the 90J43R in existing designs?

A: Yes. The 90J43RE is electrically and mechanically identical to the 90J43R. Both parts have the same resistance value (43 Ohms), tolerance (±5%), power rating (11W), temperature coefficient (±30ppm/°C), and physical dimensions (0.343" Dia x 1.811" L). The only differences are packaging format and RoHS compliance status.

Q: What is the difference between Box and Bulk packaging?

A: Box packaging typically provides individual unit packaging suitable for smaller orders or manual assembly. Bulk packaging supplies components in larger quantities without individual packaging, optimized for high-volume automated assembly and reducing packaging waste.

Q: Does the RoHS compliance difference affect electrical performance?

A: No. RoHS compliance relates to material composition and environmental regulations, not electrical performance. Both the 90J43R and 90J43RE deliver identical electrical characteristics.

Q: Are these parts interchangeable on the PCB?

A: Yes. Both parts have identical axial package dimensions (0.343" Dia x 1.811" L) and two terminations, making them fully interchangeable in through-hole PCB designs.

Q: Which part should I select for new designs?

A: For new designs, the 90J43RE is recommended due to ROHS3 compliance, higher inventory availability, and identical performance specifications. The 90J43R may be selected only if Box packaging is specifically required and RoHS non-compliance is acceptable for the application.
