KTR03EZPJ913 Equivalent & Substitute Parts

Part Overview

The KTR03EZPJ913 is a 91 kOhms ±5% thick film chip resistor manufactured by Rohm Semiconductor in 0603 (1608 Metric) package format. Rated for 0.1W power dissipation with automotive AEC-Q200 qualification, this component operates across -55°C to 155°C. The part is active in production status with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1).

Equivalent and substitute parts are identified when design requirements permit tolerance relaxation, manufacturer substitution, or packaging format changes while maintaining electrical performance and environmental ratings.

Substitute Part Grouping Explanation

Substitution eligibility is determined by three primary criteria:

Electrical Compatibility: Resistance value (91 kOhms) and power rating (0.1W) must remain constant. Tolerance may be tightened (±1%) without functional impact. Temperature coefficient may be improved (±100ppm/°C vs ±200ppm/°C).

Package Compatibility: All substitutes maintain 0603 (1608 Metric) package format with identical footprint dimensions (0.063" L × 0.031" W / 1.60mm × 0.80mm) and two terminations.

Environmental & Compliance: Substitutes must maintain ROHS3 compliance, MSL 1 rating, and operating temperature range of -55°C to 155°C. Automotive AEC-Q200 rating is preserved in qualified substitutes.

Substitutes are categorized as:

Upgrade substitutes: Tighter tolerance (±1%) or improved temperature coefficient with same or better availability
Direct equivalents: Identical electrical and mechanical specifications from alternative manufacturers
Similar alternatives: Same electrical performance with different packaging or feature sets

Engineering Selection Recommendations

For AEC-Q200 Automotive Applications: Select from KTR03EZPF9102, ERJ-3EKF9102V, RMCF0603FT91K0, or RMCF0603JT91K0. All maintain automotive qualification with ROHS3 compliance and unlimited moisture sensitivity rating. ERJ-3EKF9102V offers highest inventory availability (167,838 units) with ±1% tolerance and ±100ppm/°C temperature coefficient.

For Tolerance-Critical Designs: ERJ-3EKF9102V, RMCF0603FT91K0, and RC0603FR-0791KL provide ±1% tolerance with ±100ppm/°C temperature coefficient, improving circuit accuracy over the ±5% / ±200ppm/°C specification of KTR03EZPJ913.

For High-Volume Production: YAGEO RC0603JR-0791KL (221,211 units) and ERJ-3EKF9102V (167,838 units) provide substantial inventory depth. Both are ROHS3 compliant with MSL 1 rating and -55°C to 155°C operating range.

For Direct Equivalent Replacement: CRCW060391K0JNEA (Vishay Dale) and ERJ-3GEYJ913V (Panasonic) match the original ±5% tolerance and ±200ppm/°C temperature coefficient while maintaining identical package dimensions and electrical performance.

Frequently Asked Questions (FAQ)

Q: Can KTR03EZPF9102 replace KTR03EZPJ913 in all applications?

A: Yes, within the same manufacturer (Rohm Semiconductor). KTR03EZPF9102 provides tighter ±1% tolerance and improved ±100ppm/°C temperature coefficient. Both maintain AEC-Q200 automotive qualification, 0603 package format, 0.1W power rating, and -55°C to 155°C operating range. The tighter tolerance represents an upgrade path with no functional degradation.

Q: Are YAGEO RC0603 series parts suitable for automotive applications?

A: RC0603FR-0791KL and RC0603JR-0791KL are not AEC-Q200 qualified. They are suitable for industrial and commercial applications requiring ROHS3 compliance and MSL 1 rating. For automotive designs requiring AEC-Q200 certification, select from Rohm, Panasonic, Stackpole, or Bourns alternatives.

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

A: Tolerance defines the maximum deviation from the nominal 91 kOhm value. ±5% allows 86.45 to 95.55 kOhm range; ±1% restricts to 90.09 to 91.91 kOhm range. Tighter tolerance (±1%) is required for precision analog circuits, filters, and reference networks. Standard tolerance (±5%) is acceptable for general biasing, pull-up/pull-down, and non-critical applications.

Q: Do all substitutes maintain identical physical dimensions?

A: All listed substitutes use 0603 (1608 Metric) package with 0.063" L × 0.031" W footprint. Height-seated maximum ranges from 0.020" to 0.022" (0.50mm to 0.55mm), which is within standard PCB assembly tolerances and does not affect reflow soldering or component placement.

Q: Which substitute offers the best availability?

A: ERJ-3EKF9102V (Panasonic Electronic Components) provides 167,838 units in stock with ±1% tolerance, ±100ppm/°C temperature coefficient, and AEC-Q200 automotive qualification. RC0603JR-0791KL (YAGEO) offers 221,211 units but lacks AEC-Q200 rating.

Q: Can moisture sensitivity level (MSL 1) be exceeded in storage?

A: MSL 1 indicates unlimited shelf life without moisture absorption concerns. All listed substitutes maintain MSL 1 rating, eliminating bake-out requirements and enabling flexible inventory management across standard warehouse conditions.
