Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the CB5JB100R are qualified based on the following critical parameters:

• Resistance value: 100 Ohms (exact match required)
• Tolerance: ±5% (exact match required)
• Power rating: 5W (exact match required)
• Composition: Wirewound (exact match required)
• Package type: Axial (exact match required)
• Number of terminations: 2 (exact match required)
• RoHS compliance: ROHS3 Compliant (regulatory requirement)
• Operating temperature range: Must encompass or match the primary part's range

The identified substitutes PNP5WVJT-73-100R and SQPW5100RJ meet all critical electrical and mechanical parameters. Variations in physical dimensions, temperature coefficient, and specific feature implementations (flame retardant coating vs. flame proof) do not affect functional equivalence within the specified parameter set.

Engineering Selection Recommendations

All three parts maintain Active product status and ROHS3 compliance, qualifying them for equivalent use in applications meeting the specified electrical and mechanical requirements. Selection between CB5JB100R, PNP5WVJT-73-100R, and SQPW5100RJ should be based on:

• Operating temperature requirements: CB5JB100R and SQPW5100RJ support the full -55°C to 250°C range; PNP5WVJT-73-100R operates within -40°C to 200°C
• Packaging and supply chain considerations: Tray, Cut Tape, and Bulk formats are available across manufacturers
• Inventory availability: SQPW5100RJ (6088 units), PNP5WVJT-73-100R (2488 units), and CB5JB100R (1004 units) are in stock

Frequently Asked Questions (FAQ)

Q: Can PNP5WVJT-73-100R replace CB5JB100R in all applications?

A: PNP5WVJT-73-100R is electrically equivalent for applications operating within -40°C to 200°C. Applications requiring operation below -40°C or above 200°C require CB5JB100R or SQPW5100RJ.

Q: What is the difference between flame-proof and flame-retardant coating?

A: Both designations indicate safety features. Flame-proof and flame-retardant coatings are distinct implementations; selection depends on specific application safety requirements not defined by the provided parameters.

Q: Are the physical dimensions interchangeable?

A: All three parts use axial package configuration with 2 terminations. Dimensional variations (CB5JB100R: 9.50mm x 22.00mm; PNP5WVJT-73-100R: 7.50mm x 17.00mm; SQPW5100RJ: 10.00mm x 9.00mm x 22.00mm) may affect PCB layout and mechanical fit. Verify board design compatibility before substitution.

Q: Which substitute offers the best temperature stability?

A: CB5JB100R specifies ±200ppm/°C temperature coefficient. SQPW5100RJ specifies ±300ppm/°C. PNP5WVJT-73-100R does not provide temperature coefficient data.

Q: Are all parts RoHS compliant?

A: Yes, CB5JB100R, PNP5WVJT-73-100R, and SQPW5100RJ are all ROHS3 Compliant and REACH Unaffected.
