Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RK73H1HTTC82R0F is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Resistance value: 82 Ohms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.05W / 1/20W (exact match required)
• Temperature coefficient: ±200ppm/°C (exact match required)
• Operating temperature range: -55°C ~ 155°C (exact match required)

Mechanical Parameters:

• Package / Case: 0201 (0603 Metric) (exact match required)
• Physical dimensions: 0.024" L x 0.012" W (0.60mm x 0.30mm) (exact match required)
• Height - Seated (Max): 0.010" (0.26mm) (exact match required)
• Number of terminations: 2 (exact match required)

Compliance & Environmental Parameters:

• Automotive AEC-Q200 qualification (required for automotive applications)
• Moisture-resistant construction (required for harsh environments)
• RoHS3 compliance (required for regulatory conformance)
• MSL 1 rating (required for unlimited shelf life)

Substitute parts must satisfy all electrical, mechanical, and compliance criteria simultaneously. Deviations in any parameter disqualify a part from direct substitution.

Engineering Selection Recommendations

RK73H1HTTCM82R0F (KOA Speer Electronics, Inc.) - MFR Recommended Substitute:

This part is the manufacturer-recommended equivalent from KOA Speer Electronics, Inc. It maintains active product status and satisfies all electrical and mechanical parameters identical to the original RK73H1HTTC82R0F. However, the moisture-resistant feature specification is not documented for this variant. For applications requiring moisture-resistant construction as a critical design parameter, this substitute requires design review confirmation. The part is available in higher inventory (688 Pcs) compared to the original part status.

AC0201FR-0782RL (YAGEO) - Direct Cross-Reference Substitute:

This YAGEO part provides full electrical and mechanical equivalence with documented moisture-resistant construction matching the original specification. It maintains active product status and AEC-Q200 automotive qualification. The AC0201FR-0782RL is available in significantly higher inventory (15,825 Pcs), supporting supply chain continuity. Both parts are packaged in Tape & Reel format and comply with ROHS3 and MSL 1 requirements. This part is suitable for direct substitution in applications where the original RK73H1HTTC82R0F is specified.

Selection Criteria:

• For designs requiring moisture-resistant construction: AC0201FR-0782RL (YAGEO)
• For KOA-only supply chain requirements: RK73H1HTTCM82R0F (KOA)
• For maximum inventory availability: AC0201FR-0782RL (YAGEO)

Frequently Asked Questions (FAQ)

Q: Can RK73H1HTTCM82R0F replace RK73H1HTTC82R0F in all applications?

A: RK73H1HTTCM82R0F matches all electrical and mechanical specifications. However, the moisture-resistant feature is not explicitly documented for this variant. If moisture resistance is a critical design requirement, design review is necessary before substitution.

Q: Is AC0201FR-0782RL a direct substitute for RK73H1HTTC82R0F?

A: Yes. AC0201FR-0782RL meets all electrical parameters (82 Ohms ±1%, 0.05W, ±200ppm/°C, -55°C ~ 155°C), mechanical specifications (0201 package, identical dimensions), and compliance requirements (AEC-Q200, ROHS3, MSL 1). Moisture-resistant construction is documented for both parts.

Q: What is the significance of the "Not For New Designs" status?

A: This designation indicates the RK73H1HTTC82R0F has been superseded by the manufacturer. New designs should specify RK73H1HTTCM82R0F or equivalent active-status parts. Existing designs may continue using the original part or transition to active substitutes.

Q: Are there packaging differences between the substitutes?

A: RK73H1HTTC82R0F and AC0201FR-0782RL are both supplied in Tape & Reel (TR) packaging. RK73H1HTTCM82R0F packaging format is not specified in available documentation. Confirm packaging requirements with the supplier before procurement.

Q: Do all three parts meet automotive AEC-Q200 qualification?

A: Yes. RK73H1HTTC82R0F, RK73H1HTTCM82R0F, and AC0201FR-0782RL all carry AEC-Q200 automotive qualification and are suitable for automotive applications.

Q: What is the difference in inventory availability?

A: RK73H1HTTC82R0F: 116,613 Pcs (legacy status); RK73H1HTTCM82R0F: 688 Pcs (active); AC0201FR-0782RL: 15,825 Pcs (active). For long-term supply assurance, AC0201FR-0782RL offers higher availability.

Q: Are all parts RoHS3 compliant?

A: Yes. All three parts are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity rating, meeting regulatory and environmental requirements.
