Substitute Part Grouping Explanation

Substitution of the KTR10EZPJ821 is determined by strict equivalence in the following parameters:

Resistance value: 820 Ohms (exact match required)
Tolerance: ±5% (direct equivalents) or ±1% (upgraded tolerance acceptable)
Power rating: 0.125W minimum
Package: 0805 (2012 Metric) only
Composition: Thick film
Operating temperature range: -55°C to 155°C minimum
RoHS3 compliance required
MSL rating: 1 (Unlimited) required

Parts are grouped into two categories:

Direct Equivalents (±5% Tolerance): Parts with identical electrical specifications including ±5% tolerance, ±200ppm/°C temperature coefficient, and matching feature sets.

Upgraded Alternatives (±1% Tolerance): Parts with tighter tolerance (±1%), lower temperature coefficient (±100ppm/°C), and enhanced performance characteristics while maintaining all other mechanical and thermal compatibility.

Engineering Selection Recommendations

For Direct Equivalence (±5% Tolerance, AEC-Q200 Automotive Applications):

Select ERJ-6GEYJ821V (Panasonic) or RMCF0805JT820R (Stackpole) when maintaining identical electrical specifications to KTR10EZPJ821 is required. Both parts carry AEC-Q200 qualification, ROHS3 compliance, and MSL-1 rating. ERJ-6GEYJ821V offers the highest inventory availability (93,909 units). RMCF0805JT820R provides the largest stock depth (361,971 units) and identical height profile to the original part.

For Upgraded Performance (±1% Tolerance, Lower Temperature Coefficient):

Select ERJ-6ENF8200V (Panasonic) or RMCF0805FT820R (Stackpole) when design requirements permit tighter tolerance and improved temperature stability. Both maintain AEC-Q200 qualification and ROHS3 compliance. ERJ-6ENF8200V provides 92,354 units in stock with automotive qualification. RMCF0805FT820R offers 100,229 units with matching height profile to the original specification.

For Non-Automotive Applications:

CRCW0805820RJNEA (Vishay Dale) provides direct equivalence with the lowest profile height (0.020") and AEC-Q200 qualification with 20,300 units available. RC0805JR-07820RL (YAGEO) offers ±5% tolerance with moisture-resistant composition and 103,125 units in stock, suitable for general industrial applications.

MCR10ERTJ821 (Rohm Semiconductor) is discontinued at DiGi Electronics and should not be selected for new designs despite available inventory.

Frequently Asked Questions (FAQ)

Q: Can KTR10EZPF8200 replace KTR10EZPJ821 directly?

A: Yes. KTR10EZPF8200 is an upgraded variant with ±1% tolerance and ±100ppm/°C temperature coefficient versus the original ±5% and ±200ppm/°C. All mechanical, thermal, and compliance parameters remain compatible. The tighter tolerance provides improved circuit performance without requiring PCB redesign.

Q: Are there height differences between substitute parts?

A: Yes. Maximum seated heights vary: KTR10EZPJ821 is 0.026" (0.65mm), ERJ-6GEYJ821V is 0.028" (0.70mm), CRCW0805820RJNEA is 0.020" (0.50mm), and YAGEO parts are 0.024" (0.60mm). Verify PCB clearance requirements before substitution, particularly in high-density layouts.

Q: Which substitute parts maintain AEC-Q200 automotive qualification?

A: ERJ-6GEYJ821V, CRCW0805820RJNEA, ERJ-6ENF8200V, RMCF0805FT820R, and RMCF0805JT820R all carry AEC-Q200 qualification. KTR10EZPF8200 also qualifies. Select these for automotive applications requiring formal qualification documentation.

Q: What is the difference between ±5% and ±1% tolerance parts?

A: Tolerance defines the maximum deviation from the nominal 820 Ohm value. ±5% allows ±41 Ohms deviation (779–861 Ohms). ±1% allows ±8.2 Ohms deviation (811.8–828.2 Ohms). ±1% parts also feature lower temperature coefficient (±100ppm/°C versus ±200ppm/°C), providing superior stability across the -55°C to 155°C operating range.

Q: Is MCR10ERTJ821 suitable for new designs?

A: No. MCR10ERTJ821 is discontinued at DiGi Electronics. Although 1,136 units remain in stock, new designs should select active production parts. RMCF0805JT820R or ERJ-6GEYJ821V provide equivalent specifications with confirmed long-term availability.

Q: Can YAGEO RC0805 series parts replace Rohm KTR series?

A: Yes, with considerations. RC0805JR-07820RL matches ±5% tolerance and 0805 package but lacks AEC-Q200 qualification and features moisture-resistant composition. RC0805FR-07820RL offers ±1% tolerance with moisture resistance. Both are suitable for non-automotive applications where automotive qualification is not required.

Q: What does MSL-1 (Unlimited) mean for moisture sensitivity?

A: MSL-1 indicates the component has unlimited shelf life without moisture bake-out requirements. All listed substitute parts carry MSL-1 rating, eliminating moisture management concerns during storage and assembly.
