Key Parameters

Substitute Part Grouping Explanation

Substitution for the MNR14ERAPJ621 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
• Operating temperature range: -55°C to 155°C
• Package: 1206 (3216 Metric) with 8 pins
• Mounting: Surface mount

The YC164-JR-07620RL from YAGEO meets all these parameters and qualifies as a direct functional equivalent. Both parts share identical electrical specifications, package dimensions, and thermal characteristics, enabling pin-for-pin replacement in circuit designs.

Parameter Comparison

Engineering Selection Recommendations

The YC164-JR-07620RL is the qualified substitute for the discontinued MNR14ERAPJ621. Both components carry ROHS3 compliance and REACH unaffected status, meeting environmental regulatory requirements. The YAGEO part holds active product status with automotive-grade qualification (AEC-Q200) and is specified for DDRAM and SDRAM applications, providing additional assurance for memory interface circuits. Inventory availability for the YC164-JR-07620RL (10,865 pieces) exceeds that of the original part, supporting production continuity. The maximum seated height difference of 0.004" (0.10mm) between parts is negligible for standard PCB assembly processes and does not affect circuit performance or board layout compatibility.

Frequently Asked Questions (FAQ)

Q: Can the YC164-JR-07620RL replace the MNR14ERAPJ621 in existing designs?

A: Yes. Both parts are electrically and mechanically equivalent across all critical parameters: 620 Ohm resistance, ±5% tolerance, 62.5mW power per element, ±200ppm/°C temperature coefficient, and -55°C to 155°C operating range. The 1206 package footprint and 8-pin configuration are identical, enabling direct PCB substitution.

Q: Are there any height or dimensional differences that affect PCB assembly?

A: The seated height maximum differs by 0.004" (0.10mm), with the YC164-JR-07620RL at 0.028" versus the MNR14ERAPJ621 at 0.024". This variation is within standard PCB assembly tolerances and does not impact component placement, solder reflow, or circuit operation.

Q: What compliance certifications apply to the substitute part?

A: The YC164-JR-07620RL meets ROHS3 compliance, REACH unaffected status, and holds AEC-Q200 automotive qualification. Both parts share identical ECCN (EAR99) and HTSUS (8533.21.0020) classifications.

Q: Is the YC164-JR-07620RL suitable for memory interface applications?

A: Yes. The YAGEO part is specified for DDRAM and SDRAM applications and carries automotive-grade qualification, making it suitable for memory termination and signal conditioning circuits where the original part was used.

Q: What is the moisture sensitivity level for both parts?

A: Both the MNR14ERAPJ621 and YC164-JR-07620RL carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.
