Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RK73H1HTTC7683F are qualified based on strict equivalence across the following parameters:

Electrical Specifications: Resistance value (768 kOhms), tolerance (±1%), power rating (0.05W), temperature coefficient (±200ppm/°C), and operating temperature range (-55°C ~ 155°C) must be identical.

Mechanical Specifications: Package type (0201 / 0603 Metric), physical dimensions (0.024" L x 0.012" W / 0.60mm x 0.30mm), and seated height (0.010" / 0.26mm maximum) must match exactly.

Compliance & Ratings: AEC-Q200 automotive qualification, RoHS3 compliance, and MSL 1 rating are mandatory for substitution eligibility.

Composition & Features: Thick film construction and moisture-resistant properties must be maintained.

Substitutes are grouped into two categories: manufacturer-recommended variants from the same manufacturer (KOA Speer Electronics, Inc.) and direct cross-manufacturer equivalents (YAGEO).

Parameter Comparison

Engineering Selection Recommendations

Primary Selection: RK73H1HTTC7683F remains the baseline reference part with full moisture-resistant specification and active production status.

Manufacturer-Recommended Variant: RK73H1HTTCM7683F is a KOA Speer Electronics, Inc. variant with identical electrical and mechanical specifications. This part differs only in packaging designation and does not include moisture-resistant features in its specification. Selection of this variant is appropriate when moisture resistance is not a circuit requirement and cost optimization is a consideration. Current inventory is 974 units.

Cross-Manufacturer Equivalent: AC0201FR-07768KL from YAGEO provides full electrical and mechanical equivalence with moisture-resistant construction and AEC-Q200 automotive qualification. This part is suitable for direct substitution in applications requiring automotive-grade reliability and moisture protection. Current inventory is 877 units. All three parts maintain identical compliance certifications (RoHS3, MSL 1, AEC-Q200) and operating specifications.

Frequently Asked Questions (FAQ)

Q: Can RK73H1HTTCM7683F replace RK73H1HTTC7683F in all applications?

A: RK73H1HTTCM7683F matches all electrical and mechanical specifications. The primary difference is the absence of moisture-resistant features in the specification. Substitution is valid for applications where moisture resistance is not required. Both parts are AEC-Q200 qualified and RoHS3 compliant.

Q: Is AC0201FR-07768KL from YAGEO a direct equivalent?

A: Yes. AC0201FR-07768KL provides complete electrical and mechanical equivalence with 768 kOhms ±1% resistance, 0.05W power rating, 0201 package, ±200ppm/°C temperature coefficient, and -55°C ~ 155°C operating range. Moisture-resistant construction and AEC-Q200 automotive qualification are maintained. This part is suitable for direct substitution.

Q: Are all three parts suitable for automotive applications?

A: Yes. All three parts carry AEC-Q200 automotive qualification and are rated for -55°C ~ 155°C operating temperature. All are RoHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity ratings.

Q: What is the difference between the KOA variants RK73H1HTTC7683F and RK73H1HTTCM7683F?

A: Both parts are manufactured by KOA Speer Electronics, Inc., with identical electrical specifications (768 kOhms ±1%, 0.05W, ±200ppm/°C). The primary distinction is that RK73H1HTTC7683F includes moisture-resistant construction, while RK73H1HTTCM7683F does not specify this feature. Packaging designation differs between the two variants.

Q: Can these 0201 package resistors be used interchangeably on the same PCB?

A: Yes. All three parts share identical 0201 (0603 Metric) package dimensions: 0.024" L x 0.012" W (0.60mm x 0.30mm) with maximum seated height of 0.010" (0.26mm). They are mechanically interchangeable on PCBs designed for 0201 surface mount components.

Q: What compliance certifications apply to all substitute parts?

A: All three parts are ROHS3 compliant, AEC-Q200 qualified, carry MSL 1 (Unlimited) ratings, are REACH Unaffected, and classified under ECCN EAR99 with HTSUS code 8533.21.0030.
