Substitute Part Grouping Explanation

Substitution eligibility for the CAT10-511J4LF is determined by strict alignment of the following parameters:

• Resistance value: 510 Ohms (exact match required)
• Tolerance: ±5% (exact match required)
• Number of resistors: 4 elements (exact match required)
• Circuit type: Isolated configuration (exact match required)
• Number of pins: 8 (exact match required)
• Package / Case: 0804, Concave, Long Side Terminals (exact match required)
• Mounting type: Surface Mount (exact match required)
• Operating temperature range: -55°C ~ 125°C (exact match required)
• RoHS Status: ROHS3 Compliant (exact match required)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)

The EXB-N8V511JX from Panasonic Electronic Components meets all mandatory substitution criteria and is classified as an equivalent substitute part.

Parameter Comparison

Engineering Selection Recommendations

Both the CAT10-511J4LF and EXB-N8V511JX maintain Active product status and are ROHS3 compliant with MSL 1 (Unlimited) rating. Selection between these components should be based on application-specific power dissipation requirements. The CAT10-511J4LF provides 62.5mW power per element, while the EXB-N8V511JX provides 31mW power per element. The EXB-N8V511JX exhibits superior temperature coefficient stability at ±200ppm/°C compared to the CAT10-511J4LF at ±250ppm/°C. Both components are mechanically and electrically compatible for direct substitution in 0804 surface mount applications.

Frequently Asked Questions (FAQ)

Q: Can the EXB-N8V511JX directly replace the CAT10-511J4LF in existing designs?

A: Yes. Both components share identical resistance value (510 Ohms), tolerance (±5%), circuit configuration (Isolated 4-resistor network), pin count (8), package type (0804, Concave, Long Side Terminals), and operating temperature range (-55°C ~ 125°C). Mechanical and electrical compatibility is confirmed.

Q: What is the primary difference between these two parts?

A: The primary differences are power dissipation per element (CAT10-511J4LF: 62.5mW vs. EXB-N8V511JX: 31mW) and temperature coefficient (CAT10-511J4LF: ±250ppm/°C vs. EXB-N8V511JX: ±200ppm/°C). Applications with lower power requirements or requiring tighter temperature stability may benefit from the EXB-N8V511JX.

Q: Are both parts RoHS compliant?

A: Yes. Both the CAT10-511J4LF and EXB-N8V511JX are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Q: What package configuration do these components use?

A: Both components use 0804 surface mount package with Concave, Long Side Terminals configuration. Physical dimensions are identical: 0.079" L x 0.039" W (2.00mm x 1.00mm) with maximum seated height of 0.022" (0.55mm).
