Substitute Part Grouping Explanation

Substitution of the EP3WS330RJ is determined by strict equivalence across the following critical parameters:

• Resistance Value: 330 Ohms (exact match required)
• Tolerance: ±5% (exact match required)
• Power Rating: 3W (exact match required)
• Composition: Wirewound (exact match required)
• Package Configuration: Axial through-hole (exact match required)
• Temperature Coefficient: ±300ppm/°C (exact match required)
• Operating Temperature Range: -55°C to 155°C (exact match required)
• Physical Dimensions: 0.256" Dia x 0.689" L / 6.50mm x 17.50mm (exact match required)
• Regulatory Compliance: ROHS3 Compliant (exact match required)

The identified substitute part maintains identical electrical and mechanical specifications. The primary difference is packaging format: the main part is supplied in Tape & Box (TB) configuration, while the substitute is available in Cut Tape (CT) format. Both are manufactured by TE Connectivity Passive Product within the EP/Neohm series.

Parameter Comparison

Engineering Selection Recommendations

Both EP3WS330RJ and 1-2176079-0 are active production components from TE Connectivity Passive Product with identical electrical and mechanical specifications. Selection between these parts is determined by packaging requirements and inventory availability:

EP3WS330RJ (Tape & Box): Select this part number when Tape & Box packaging is required for automated assembly processes or when bulk quantities with protective boxing are specified.

1-2176079-0 (Cut Tape): Select this part number when Cut Tape packaging is acceptable or preferred, or when higher inventory availability is required. This part number currently has 5047 pieces in stock compared to 694 pieces for the main part number.

Both parts maintain ROHS3 compliance and are suitable for applications requiring flame retardant, pulse-withstanding, safety-rated wirewound resistors across the -55°C to 155°C operating temperature range.

Frequently Asked Questions (FAQ)

Q: Can EP3WS330RJ be directly replaced with 1-2176079-0 in circuit applications?

A: Yes. Both parts are electrically and mechanically identical with matching 330 Ohm resistance, ±5% tolerance, 3W power rating, and axial through-hole configuration. The only difference is packaging format (Tape & Box versus Cut Tape).

Q: What is the difference between Tape & Box and Cut Tape packaging?

A: Tape & Box (TB) packaging supplies components on continuous tape wound on a reel and enclosed in a protective box. Cut Tape (CT) packaging supplies components on tape segments cut to specific lengths. Both formats are suitable for through-hole assembly; selection depends on assembly equipment compatibility and handling preferences.

Q: Are the physical dimensions identical between these two part numbers?

A: Yes. Both parts have identical dimensions of 0.256" diameter by 0.689" length (6.50mm x 17.50mm). They are mechanically interchangeable on PCBs.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both EP3WS330RJ and 1-2176079-0 are ROHS3 compliant and carry identical safety certifications for flame retardant coating and pulse withstanding capability.

Q: Which part should be selected if inventory is a critical factor?

A: Part number 1-2176079-0 has significantly higher inventory availability with 5047 pieces in stock compared to 694 pieces for EP3WS330RJ. If lead time or stock availability is a concern, 1-2176079-0 is the preferred selection.

Q: Are there any temperature or performance differences between these parts?

A: No. Both parts operate across the identical temperature range of -55°C to 155°C with matching temperature coefficient of ±300ppm/°C. Performance characteristics are equivalent.
