KTR10EZPJ621 Equivalent & Substitute Parts

Part Overview

The KTR10EZPJ621 is a 620 Ohm ±5% thick film chip resistor in 0805 (2012 Metric) package rated for 0.125W (1/8W) power dissipation. This Rohm Semiconductor component is qualified to AEC-Q200 automotive standards and features high voltage capability. The part is currently active in production. Equivalent and substitute parts are necessary when the primary part experiences supply constraints, when design requirements demand higher tolerance specifications, or when alternative packaging formats are required for manufacturing optimization.

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence across the following parameters: resistance value (620 Ohms), package format (0805), power rating (0.125W), composition (thick film), operating temperature range (-55°C to 155°C), and compliance certifications (ROHS3, REACH Unaffected). Parts are grouped into two categories:

Direct Equivalents (±5% Tolerance): Parts maintaining identical tolerance specification and automotive AEC-Q200 qualification. These provide one-to-one functional replacement without circuit redesign.

Upgraded Alternatives (±1% Tolerance): Parts offering improved tolerance performance (±1% versus ±5%) with lower temperature coefficient (±100ppm/°C versus ±200ppm/°C). These are suitable for applications requiring tighter resistance control and are backward compatible with designs specified for ±5% tolerance.

Engineering Selection Recommendations

For Direct Replacement (Same Tolerance): Select from ERJ-6GEYJ621V (Panasonic), CRCW0805620RJNEA (Vishay Dale), or RMCF0805JT620R (Stackpole Electronics Inc). All three maintain ±5% tolerance, ±200ppm/°C temperature coefficient, and AEC-Q200 automotive qualification. ERJ-6GEYJ621V offers the highest inventory availability (73,665 units). CRCW0805620RJNEA and RMCF0805JT620R are available in Tape & Reel packaging consistent with the primary part.

For Upgraded Performance: Select from KTR10EZPF6200 (Rohm Semiconductor), ERJ-6ENF6200V (Panasonic), or RMCF0805FT620R (Stackpole Electronics Inc). These parts provide ±1% tolerance and ±100ppm/°C temperature coefficient while maintaining AEC-Q200 qualification. KTR10EZPF6200 maintains the same manufacturer as the primary part. ERJ-6ENF6200V and RMCF0805FT620R offer substantial inventory depth (70,239 and 320,220 units respectively).

Avoid MCR10ERTJ621: This Rohm Semiconductor part is discontinued at DiGi Electronics and should not be selected for new designs despite matching electrical specifications.

Frequently Asked Questions (FAQ)

Q: Can I use a ±1% tolerance part as a substitute for the ±5% specification?

A: Yes. Parts with ±1% tolerance are backward compatible with designs specified for ±5% tolerance. The tighter tolerance provides improved circuit performance without requiring design modification.

Q: What is the significance of AEC-Q200 qualification?

A: AEC-Q200 certification indicates the part meets automotive industry reliability standards for passive components. For automotive applications, select only AEC-Q200 qualified substitutes. For non-automotive applications, non-qualified parts are acceptable.

Q: Does packaging format affect electrical performance?

A: No. Tape & Reel and Cut Tape & Digi-Reel packaging formats contain identical components. Selection depends on manufacturing process requirements and reel compatibility with assembly equipment.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance and REACH Unaffected status, matching the primary part's environmental certification.

Q: What is the difference between temperature coefficient values?

A: Temperature coefficient indicates resistance change per degree Celsius. ±100ppm/°C (upgraded parts) provides superior stability across temperature extremes compared to ±200ppm/°C (direct equivalents). For precision analog circuits, lower temperature coefficient is preferred.

Q: Can I mix different manufacturers in the same design?

A: Yes. All substitute parts share identical electrical specifications, package dimensions, and compliance certifications. Multi-source designs are acceptable for supply chain resilience.
