Substitute Part Grouping Explanation

Substitute parts for the Ohmite 91J350 are identified based on strict electrical and mechanical parameter matching. The following criteria determine substitution eligibility:

• Resistance value: 350 Ohms (exact match required)
• Tolerance: ±5% (exact match required)
• Power rating: 1.5W (exact match required)
• Composition: Wirewound (exact match required)
• Package type: Axial (exact match required)
• Temperature coefficient: ±30ppm/°C (exact match required)
• Physical dimensions: 0.142" Dia x 0.453" L / 3.60mm x 11.50mm (exact match required)
• Terminations: 2 (exact match required)

The substitute part 91J350E meets all electrical and mechanical parameters identically to the main part number. The primary difference is packaging format (Bulk versus standard) and RoHS compliance status.

Parameter Comparison

Engineering Selection Recommendations

The 91J350E serves as a direct parametric equivalent to the 91J350. Both parts are manufactured by Ohmite and maintain identical electrical and mechanical specifications. Selection between these part numbers should be based on the following factors:

• RoHS Compliance: The 91J350E is ROHS3 compliant, while the 91J350 is RoHS non-compliant. Applications requiring RoHS compliance must use the 91J350E.
• Packaging Requirements: The 91J350E is supplied in Bulk packaging, whereas the 91J350 uses standard packaging. Procurement volume and handling requirements may influence part selection.
• Product Status: Both parts maintain Active status with current inventory availability.
• Moisture Sensitivity: The 91J350E specifies MSL 1 (Unlimited), providing broader storage and handling flexibility compared to the 91J350 (Not Applicable).

Frequently Asked Questions (FAQ)

Q: Can the 91J350E be used as a direct replacement for the 91J350 in all applications?

A: Yes, the 91J350E is electrically and mechanically identical to the 91J350. Both parts share the same resistance value (350 Ohms), tolerance (±5%), power rating (1.5W), composition (Wirewound), package type (Axial), temperature coefficient (±30ppm/°C), and physical dimensions (0.142" Dia x 0.453" L). The primary differences are packaging format and RoHS compliance status.

Q: What is the difference in packaging between these two part numbers?

A: The 91J350 is supplied in standard packaging, while the 91J350E is supplied in Bulk packaging. This distinction affects order quantities, handling procedures, and storage considerations but does not impact electrical or mechanical performance.

Q: Which part should I select for RoHS-compliant applications?

A: The 91J350E is ROHS3 compliant and must be used for applications requiring RoHS compliance. The 91J350 is RoHS non-compliant and is not suitable for such applications.

Q: Are the physical dimensions identical between these parts?

A: Yes, both the 91J350 and 91J350E have identical physical dimensions of 0.142" Dia x 0.453" L (3.60mm x 11.50mm). They are mechanically interchangeable in PCB layouts and mechanical assemblies.

Q: What is the moisture sensitivity level for each part?

A: The 91J350E specifies MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. The 91J350 lists MSL as Not Applicable. The 91J350E provides more flexible storage and handling conditions.
