Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 20J75R are identified based on strict electrical and mechanical parameter matching. The substitution criteria are:

• Resistance value: 75 Ohms (exact match required)
• Tolerance: ±5% (exact match required)
• Power rating: 10W (exact match required)
• Composition: Wirewound (exact match required)
• Package: Axial (exact match required)
• Physical dimensions: 0.394" Dia x 1.858" L (exact match required)
• Temperature coefficient: ±30ppm/°C (exact match required)
• Features: Flame retardant coating and safety features (exact match required)

The 20J75RE meets all substitution criteria and is classified as a direct equivalent. The primary difference is packaging configuration (Bulk versus standard packaging) and RoHS compliance status.

Parameter Comparison

Engineering Selection Recommendations

Both the 20J75R and 20J75RE are active production components from Ohmite with identical electrical and mechanical specifications. Selection between these parts depends on regulatory compliance requirements:

The 20J75R is RoHS non-compliant and suitable for applications without RoHS restrictions. The 20J75RE is ROHS3 compliant and required for applications subject to RoHS3 regulations. Both parts maintain REACH Unaffected status. The 20J75RE offers higher current inventory availability (1579 units versus 1146 units), which may influence lead time considerations. Packaging configuration differs between the two parts, with 20J75RE supplied in Bulk packaging.

Frequently Asked Questions (FAQ)

Q: Can the 20J75RE replace the 20J75R in all applications?

A: The 20J75RE is electrically and mechanically identical to the 20J75R. Substitution is valid for all applications where the component specifications match the design requirements. RoHS compliance status must be verified against application regulatory requirements.

Q: What is the difference between the 20J75R and 20J75RE?

A: The parts are identical in electrical performance and physical dimensions. The primary differences are RoHS compliance status (20J75R is non-compliant; 20J75RE is ROHS3 compliant) and packaging configuration (20J75RE is supplied in Bulk packaging).

Q: Are the physical dimensions identical between substitute parts?

A: Yes. Both the 20J75R and 20J75RE share identical dimensions of 0.394" Dia x 1.858" L (10.00mm x 47.20mm), ensuring direct mechanical compatibility in PCB layouts and through-hole applications.

Q: Which part should be selected for RoHS-regulated applications?

A: The 20J75RE is ROHS3 compliant and must be used for applications subject to RoHS3 regulations. The 20J75R is non-compliant and suitable only for applications without RoHS restrictions.

Q: Do both parts have the same temperature coefficient?

A: Yes. Both the 20J75R and 20J75RE have a temperature coefficient of ±30ppm/°C, ensuring identical thermal performance characteristics across the operating temperature range.
