Substitute Part Grouping Explanation

Substitution eligibility for the RK73H1HTTC4223F is determined by strict equivalence across the following parameters:

Electrical Specifications:

• Resistance value: 422 kOhms
• Tolerance: ±1%
• Power rating: 0.05W (1/20W)
• Temperature coefficient: ±200ppm/°C
• Operating temperature range: -55°C ~ 155°C

Mechanical Specifications:

• Package format: 0201 (0603 Metric)
• Physical dimensions: 0.024" L x 0.012" W (0.60mm x 0.30mm)
• Height seated (max): 0.010" (0.26mm)
• Number of terminations: 2

Compliance & Environmental:

• Automotive qualification: AEC-Q200
• Composition: Thick Film
• RoHS compliance: ROHS3
• Moisture sensitivity: MSL 1 (Unlimited)

Substitute parts must match all electrical parameters, maintain identical package dimensions, and retain automotive AEC-Q200 certification. Moisture-resistant characteristics are preserved across all identified substitutes.

Engineering Selection Recommendations

Primary Selection: RK73H1HTTC4223F

The original KOA Speer Electronics part RK73H1HTTC4223F maintains full specification compliance with moisture-resistant characteristics and AEC-Q200 automotive qualification. This part is the baseline reference for all substitution analysis.

Equivalent Substitute: AC0201FR-07422KL (YAGEO)

The YAGEO AC0201FR-07422KL provides direct electrical and mechanical equivalence to the primary part. All critical parameters align: 422 kOhm resistance, ±1% tolerance, 0.05W power rating, 0201 package format, ±200ppm/°C temperature coefficient, -55°C to 155°C operating range, and AEC-Q200 automotive certification. Moisture-resistant properties are maintained. RoHS3 compliance and MSL 1 rating are identical. This part is suitable for direct substitution in automotive applications.

Alternative Substitute: RK73H1HTTCM4223F (KOA)

The KOA Speer Electronics part RK73H1HTTCM4223F is electrically and mechanically equivalent to the primary part across all specified parameters. However, moisture-resistant characteristics are not documented for this variant. This part maintains AEC-Q200 certification, RoHS3 compliance, and MSL 1 rating. Selection of this part should be based on application requirements regarding moisture resistance.

Compliance Basis:

All three parts maintain ROHS3 compliance, AEC-Q200 automotive qualification, and MSL 1 moisture sensitivity rating. Selection among these parts is determined by specific application requirements regarding moisture resistance and manufacturer preference within supply chain constraints.

Frequently Asked Questions (FAQ)

Q: Can RK73H1HTTC4223F be replaced with AC0201FR-07422KL in automotive applications?

A: Yes. The AC0201FR-07422KL meets all electrical specifications (422 kOhm ±1%, 0.05W), maintains identical 0201 package dimensions, retains AEC-Q200 automotive certification, and preserves moisture-resistant characteristics. Both parts are ROHS3 compliant with MSL 1 rating.

Q: What is the difference between RK73H1HTTC4223F and RK73H1HTTCM4223F?

A: Both parts are manufactured by KOA Speer Electronics with identical electrical and mechanical specifications. The primary documented difference is that moisture-resistant characteristics are specified for RK73H1HTTC4223F but not documented for RK73H1HTTCM4223F. Both maintain AEC-Q200 certification and ROHS3 compliance.

Q: Are all substitute parts qualified for the same temperature range?

A: Yes. All identified substitute parts operate across the -55°C to 155°C temperature range with ±200ppm/°C temperature coefficient, meeting automotive environmental requirements.

Q: Does package format remain consistent across all substitutes?

A: Yes. All substitute parts use the 0201 package format (0603 Metric) with identical physical dimensions of 0.024" L x 0.012" W (0.60mm x 0.30mm) and maximum seated height of 0.010" (0.26mm).

Q: Are moisture sensitivity levels equivalent across all parts?

A: Yes. All identified parts carry MSL 1 (Unlimited) rating, indicating unlimited shelf life without moisture bake requirements.

Q: Can these parts be used interchangeably in PCB assembly?

A: Yes, from a mechanical and electrical standpoint. All parts share identical 0201 package specifications, two terminations, and equivalent electrical performance. Assembly processes and handling procedures remain unchanged.
