Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence across the following parameters: resistance value (91 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 (±5%) and temperature coefficient (±200ppm/°C). These provide one-to-one functional replacement without circuit performance modification.

Upgrade Equivalents (±1% Tolerance): Parts with improved tolerance specification (±1%) and reduced temperature coefficient (±100ppm/°C). These provide enhanced precision and thermal stability while maintaining all other electrical and mechanical parameters. Upgrade parts are suitable for applications requiring tighter tolerance control.

Engineering Selection Recommendations

For Direct Replacement (±5% Tolerance Requirement):

Select from active production parts with AEC-Q200 certification: ERJ-6GEYJ910V (Panasonic), CRCW080591R0JNEA (Vishay Dale), or RMCF0805JT91R0 (Stackpole). These maintain identical electrical specifications and automotive compliance. ERJ-6GEYJ910V offers highest inventory availability (71,352 units). CRCW080591R0JNEA provides alternative sourcing from Vishay Dale. RMCF0805JT91R0 ensures AEC-Q200 compliance with Stackpole manufacturing.

For Upgraded Performance (±1% Tolerance Requirement):

Select from active production parts with AEC-Q200 certification: KTR10EZPF91R0 (Rohm), ERJ-6ENF91R0V (Panasonic), or RMCF0805FT91R0 (Stackpole). These provide improved tolerance and reduced temperature coefficient while maintaining automotive qualification. ERJ-6ENF91R0V offers exceptional inventory depth (285,455 units) and active status. KTR10EZPF91R0 maintains Rohm platform continuity. RMCF0805FT91R0 provides Stackpole alternative with AEC-Q200 rating.

For Non-Automotive Applications:

RC0805FR-0791RL (YAGEO, ±1%) or RC0805JR-0791RL (YAGEO, ±5%) are suitable when AEC-Q200 certification is not required. Both feature moisture-resistant composition and active production status.

Avoid:

MCR10ERTJ910 and MCR10ERTF91R0 are discontinued at DiGi Electronics and should not be selected for new designs despite current inventory availability.

Frequently Asked Questions (FAQ)

Q: Can MCR10ERTJ910 be used as a direct replacement for KTR10EZPJ910?

A: MCR10ERTJ910 matches all electrical parameters (91 Ohms, ±5%, 0.125W, 0805 package, ±200ppm/°C) and operating temperature range. However, this part is discontinued at DiGi Electronics. For new designs, select active production equivalents: ERJ-6GEYJ910V, CRCW080591R0JNEA, or RMCF0805JT91R0.

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

A: Tolerance specifies the maximum deviation from the nominal 91 Ohm value. ±5% tolerance allows deviation up to 4.55 Ohms (range: 86.45–95.55 Ohms). ±1% tolerance restricts deviation to 0.91 Ohms (range: 90.09–91.91 Ohms). ±1% parts also feature reduced temperature coefficient (±100ppm/°C vs. ±200ppm/°C), providing superior thermal stability. Select ±1% parts when circuit design requires tighter resistance control.

Q: Are all substitute parts AEC-Q200 qualified?

A: No. AEC-Q200 certification is present in KTR10EZPJ910, KTR10EZPF91R0, ERJ-6GEYJ910V, ERJ-6ENF91R0V, CRCW080591R0JNEA, RMCF0805JT91R0, and RMCF0805FT91R0. YAGEO RC series (RC0805FR-0791RL, RC0805JR-0791RL) lack AEC-Q200 rating. For automotive applications, select only AEC-Q200 qualified parts.

Q: Does packaging format affect electrical performance?

A: No. Tape & Reel (TR) and Cut Tape & Digi-Reel packaging formats do not affect electrical characteristics. Selection depends on manufacturing process requirements and assembly equipment compatibility. KTR10EZPJ910 uses Tape & Reel format; MCR10ERTJ910 uses Cut Tape & Digi-Reel format. Both are electrically equivalent.

Q: Can I substitute a ±1% part where ±5% is specified?

A: Yes. ±1% tolerance parts are suitable for applications designed for ±5% tolerance, as they provide superior precision. This substitution improves circuit performance without modification. Reverse substitution (±5% for ±1% requirement) is not acceptable.

Q: What is the significance of temperature coefficient in resistor selection?

A: Temperature coefficient (ppm/°C) indicates resistance change per degree Celsius. KTR10EZPJ910 has ±200ppm/°C; upgrade parts have ±100ppm/°C. At 100°C temperature change, a ±200ppm/°C resistor drifts approximately 2% from nominal value; a ±100ppm/°C resistor drifts approximately 1%. Select lower temperature coefficient parts for applications with wide operating temperature ranges or stringent stability requirements.

Q: Are all parts ROHS3 compliant?

A: Yes. All listed parts maintain ROHS3 compliance and REACH Unaffected status, meeting environmental and regulatory requirements for commercial and automotive applications.
