RK73B2HTTE162J Equivalent & Substitute Parts

Part Overview

The RK73B2HTTE162J is a 1.6 kOhms ±5% 0.75W chip resistor in 2010 (5025 Metric) package manufactured by KOA Speer Electronics, Inc. This thick film automotive-grade resistor meets AEC-Q200 qualification standards and is designed for high-reliability applications requiring temperature stability across -55°C to 155°C operating range. The part is currently in active production status with 3833 units available in inventory.

Substitute parts become necessary when the primary part experiences supply constraints, extended lead times, or when design flexibility permits component sourcing from alternative qualified manufacturers while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RK73B2HTTE162J is determined by strict equivalence across the following critical parameters:

• Resistance value: 1.6 kOhms (exact match required)
• Tolerance: ±5% (exact match required)
• Power rating: 0.75W (exact match required)
• Package: 2010 (5025 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Temperature coefficient: ±200ppm/°C (exact match required)
• Operating temperature range: -55°C ~ 155°C (exact match required)
• Automotive qualification: AEC-Q200 (exact match required)
• RoHS compliance: ROHS3 Compliant (exact match required)

All identified substitute parts meet these criteria and are therefore electrically and mechanically interchangeable with the primary part number.

Parameter Comparison

Engineering Selection Recommendations

RK73B2HTTE162J (Primary Part): Active production status with established supply chain. Recommended for new designs requiring long-term component availability and manufacturer support.

ERJ-12ZYJ162U (Panasonic Substitute): Meets all electrical and mechanical equivalence criteria. However, product status is marked "Not For New Designs," indicating this part is in end-of-life phase. Suitable only for legacy system maintenance or when primary part availability is constrained and design refresh is not planned.

RMCF2010JT1K60 (Stackpole Substitute): Active production status with full compliance to all specified parameters. Represents a viable alternative for new designs. Available in Cut Tape (CT) packaging versus the primary part's Tape & Reel (TR) format; packaging selection depends on assembly process requirements.

Frequently Asked Questions (FAQ)

Q: Can ERJ-12ZYJ162U be used in new product designs? A: ERJ-12ZYJ162U meets all electrical and mechanical specifications for direct substitution. However, its "Not For New Designs" status indicates the manufacturer is discontinuing this product line. For new designs with long production lifecycles, RK73B2HTTE162J or RMCF2010JT1K60 are preferred due to active production status.

Q: What is the difference between Tape & Reel (TR) and Cut Tape (CT) packaging? A: Tape & Reel packaging is supplied on continuous reels suitable for automated pick-and-place assembly equipment. Cut Tape packaging is supplied in smaller quantities on individual tape segments, typically for lower-volume or manual assembly processes. Both packaging formats contain electrically identical components.

Q: Are all three parts pin-compatible? A: Yes. All three parts are 2-termination chip resistors in 2010 (5025 Metric) package with identical footprint dimensions (0.197" L x 0.098" W, 5.00mm x 2.50mm). They are directly interchangeable on PCB layouts without modification.

Q: Do all substitute parts meet automotive qualification requirements? A: Yes. All listed parts carry AEC-Q200 automotive qualification and ROHS3 compliance certification, meeting the same reliability and environmental standards as the primary part.

Q: What is the significance of ±200ppm/°C temperature coefficient? A: Temperature coefficient specifies resistance value drift per degree Celsius change. ±200ppm/°C indicates the resistance will shift by a maximum of 0.02% per °C across the -55°C to 155°C operating range. All substitute parts maintain this specification for consistent circuit performance across temperature extremes.
