Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RK73B2BTTD162J are qualified based on the following criteria:

Electrical Parameters: Resistance value (1.6 kOhms), tolerance (±5%), power rating (0.25W), and temperature coefficient (±200ppm/°C) must match exactly.

Mechanical Parameters: Package type (1206 / 3216 Metric) and number of terminations (2) must be identical to ensure PCB footprint compatibility.

Environmental & Compliance: Automotive AEC-Q200 rating, operating temperature range (-55°C to 155°C), RoHS3 compliance, and MSL 1 classification must be maintained.

Composition: Thick film construction is required for consistency with the original part's performance characteristics.

Substitute parts are categorized as Direct or Similar based on product status and availability. Direct substitutes maintain active production status. Similar substitutes may have limited availability or restricted design-in status but retain full electrical and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Direct Substitutes (Active Production):

CRCW12061K60JNEA (Vishay Dale) and RMCF1206JG1K60 (Stackpole Electronics Inc) are qualified direct substitutes. Both maintain active product status, full AEC-Q200 automotive compliance, and identical electrical specifications. CRCW12061K60JNEA is available in Tape & Reel packaging with 19,499 units in stock. RMCF1206JG1K60 is available in Cut Tape packaging with 8,458 units in stock. Both parts meet all compliance requirements including RoHS3 and MSL 1 classification.

Similar Substitute (Restricted Design-In):

ERJ-8GEYJ162V (Panasonic Electronic Components) is a similar substitute with full electrical and mechanical compatibility. This part carries a "Not For New Designs" product status, indicating it is restricted from new design implementations. However, it remains suitable for replacement in existing applications and field service scenarios. The part is available in high volume (153,072 units in stock) and maintains all required automotive and environmental certifications.

Packaging Considerations:

Height variation exists between substitutes. The CRCW12061K60JNEA has a maximum seated height of 0.024" (0.60mm), while RK73B2BTTD162J, RMCF1206JG1K60, and ERJ-8GEYJ162V all have 0.028" (0.70mm). Verify PCB clearance requirements before substitution in space-constrained applications.

Frequently Asked Questions (FAQ)

Q: Can CRCW12061K60JNEA be used as a direct replacement for RK73B2BTTD162J?

A: Yes. CRCW12061K60JNEA meets all electrical specifications (1.6 kOhms ±5%, 0.25W), operates across the same temperature range (-55°C to 155°C), maintains AEC-Q200 automotive qualification, and uses the identical 1206 package. Both are active production parts with full RoHS3 and MSL 1 compliance.

Q: What is the difference between the substitute parts?

A: All three substitutes (CRCW12061K60JNEA, RMCF1206JG1K60, and ERJ-8GEYJ162V) share identical electrical and mechanical specifications. The primary differences are manufacturer, packaging format (Tape & Reel vs. Cut Tape), seated height (0.024" vs. 0.028"), and product status. CRCW12061K60JNEA and RMCF1206JG1K60 are active production parts; ERJ-8GEYJ162V is restricted from new designs.

Q: Is ERJ-8GEYJ162V suitable for new product designs?

A: No. ERJ-8GEYJ162V carries a "Not For New Designs" status and should not be selected for new product development. Use CRCW12061K60JNEA or RMCF1206JG1K60 for new designs. ERJ-8GEYJ162V is appropriate only for replacement and field service applications.

Q: Does the height difference between substitutes affect PCB compatibility?

A: The height difference (0.024" vs. 0.028") is minimal but may be relevant in space-constrained applications. CRCW12061K60JNEA has the lowest profile at 0.024" (0.60mm). Verify clearance requirements for your specific PCB layout before substitution.

Q: Are all substitutes automotive-qualified?

A: Yes. All substitute parts (CRCW12061K60JNEA, RMCF1206JG1K60, and ERJ-8GEYJ162V) maintain AEC-Q200 automotive qualification and operate across -55°C to 155°C, matching the original RK73B2BTTD162J specifications.

Q: What packaging options are available?

A: RK73B2BTTD162J and CRCW12061K60JNEA are supplied in Tape & Reel (TR) format. RMCF1206JG1K60 is supplied in Cut Tape (CT) format. Select based on your assembly process requirements and volume needs.
