Substitute Part Grouping Explanation

Substitute parts for the Ohmite 93J680 are identified based on strict electrical and mechanical parameter matching:

Substitution Criteria:

• Resistance value: 680 Ohms
• Tolerance: ±5%
• Power rating: 3.25W
• Composition: Wirewound
• Package type: Axial
• Temperature coefficient: ±30ppm/°C
• Features: Flame retardant coating, safety characteristics
• Physical dimensions: 0.232"-0.233" Dia x 0.579" L (5.90mm x 14.70mm)
• Terminations: 2-pin axial configuration

The Ohmite 93J680E meets all electrical and mechanical requirements for direct substitution. Packaging differences (Box vs. Bulk) do not affect component functionality or circuit performance.

Parameter Comparison

Engineering Selection Recommendations

Both the Ohmite 93J680 and 93J680E are active products from the same manufacturer series with identical electrical specifications and mechanical compatibility. Selection between these parts should be based on:

Compliance Requirements: The 93J680E offers ROHS3 compliance, making it suitable for applications with RoHS regulatory requirements. The 93J680 is RoHS non-compliant and should be selected only when legacy or non-compliant designs are specified.

Packaging Considerations: The 93J680 is supplied in Box packaging, while the 93J680E is supplied in Bulk packaging. Packaging selection depends on procurement volume and inventory management requirements rather than functional performance.

Availability: Both parts maintain active inventory status. Selection may be driven by current stock levels and lead time requirements.

Frequently Asked Questions (FAQ)

Q: Can the 93J680E directly replace the 93J680 in existing designs?

A: Yes. Both parts share identical electrical parameters (680 Ohms ±5%, 3.25W), composition (wirewound), temperature coefficient (±30ppm/°C), and axial package configuration. Physical dimensions are equivalent within manufacturing tolerances (0.232"-0.233" diameter). Direct substitution is electrically and mechanically valid.

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

A: Packaging format affects procurement and storage only. Box packaging typically includes individual component packaging, while Bulk packaging consolidates units for higher-volume orders. Electrical and mechanical performance is identical.

Q: Does RoHS compliance affect component selection?

A: RoHS compliance is a regulatory and procurement consideration, not a functional performance factor. The 93J680E (ROHS3 compliant) is required for applications subject to RoHS regulations. The 93J680 (non-compliant) is suitable for applications without RoHS requirements.

Q: Are the physical dimensions identical between these parts?

A: Dimensions are equivalent within standard manufacturing tolerances. The 93J680 specifies 0.232" diameter, while the 93J680E specifies 0.233" diameter. Both maintain the same 0.579" length and fit standard axial component footprints.

Q: Can these parts be used interchangeably in PCB designs?

A: Yes. Both parts use identical 2-pin axial termination and fit standard through-hole resistor footprints. No PCB layout modifications are required for substitution.
