Substitute Part Grouping Explanation

Substitution eligibility for the YC124-JR-07620RL is determined by strict equivalence across the following critical parameters:

• Resistance value: 620 Ohm
• Tolerance: ±5%
• Circuit configuration: Isolated 4-resistor network
• Power rating per element: 62.5mW
• Temperature coefficient: ±200ppm/°C
• Package type: 0804 with convex, long side terminals
• Pin count: 8
• Surface mount compatibility
• Regulatory compliance: ROHS3, REACH Unaffected, EAR99

The EXB-28V621JX from Panasonic Electronic Components meets all these criteria and qualifies as a direct substitute.

Parameter Comparison

Engineering Selection Recommendations

Both the YC124-JR-07620RL and EXB-28V621JX are active products with ROHS3 compliance and REACH unaffected status, qualifying them for use in regulated applications including automotive AEC-Q200 circuits. The primary distinction is the operating temperature range: the YAGEO part extends to 155°C while the Panasonic part reaches 125°C. Selection should be based on the specific thermal requirements of the application. For applications operating within -55°C to 125°C, either part is functionally equivalent. For applications requiring operation above 125°C, the YC124-JR-07620RL is the appropriate choice. Physical dimensions and pin configuration are identical, ensuring direct PCB compatibility.

Frequently Asked Questions (FAQ)

Q: Can the EXB-28V621JX replace the YC124-JR-07620RL in all applications?

A: The EXB-28V621JX is electrically and mechanically equivalent for applications with maximum operating temperatures up to 125°C. Applications requiring operation above 125°C must use the YC124-JR-07620RL due to its extended temperature range to 155°C.

Q: Are there physical compatibility concerns when substituting these parts?

A: No. Both parts use identical 0804 package dimensions (2.00mm x 1.00mm) with convex, long side terminals and 8-pin configurations. The seated height difference (0.55mm vs 0.45mm) is within typical PCB assembly tolerances and does not affect placement or functionality.

Q: Do both parts meet automotive qualification requirements?

A: Yes. Both the YC124-JR-07620RL and EXB-28V621JX are qualified for automotive AEC-Q200 applications and carry ROHS3 compliance.

Q: What is the significance of the ±200ppm/°C temperature coefficient?

A: The temperature coefficient specifies the maximum change in resistance value per degree Celsius across the operating temperature range. Both parts maintain this specification, ensuring predictable performance in temperature-sensitive circuits.

Q: Are moisture sensitivity considerations different between these parts?

A: No. Both parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions for storage or handling.
