AF2010JK-07300RL Equivalent & Substitute Parts

Part Overview

The AF2010JK-07300RL is a 300 Ohm ±5% 0.75W chip resistor in 2010 (5025 Metric) package manufactured by YAGEO. This thick film resistor features anti-sulfur coating and automotive AEC-Q200 qualification, designed for high-reliability applications in automotive and industrial environments. The part is currently active in production with 1180 pieces in stock.

Equivalent and substitute parts are identified based on matching electrical specifications (resistance value, power rating, tolerance), mechanical compatibility (package size and termination count), and environmental ratings. Alternative sources and tolerance grades are available to support supply chain flexibility and design optimization.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AF2010JK-07300RL is determined by the following critical parameters:

• Electrical Match: Resistance value (300 Ohms) and power rating (0.75W) must be identical
• Package Compatibility: 2010 (5025 Metric) package with 2 terminations required for PCB footprint compatibility
• Environmental Specifications: Operating temperature range (-55°C ~ 155°C) and temperature coefficient (±100ppm/°C) must be maintained
• Regulatory Compliance: RoHS3 compliance and MSL 1 rating required

Tolerance variations (±5% vs ±1%) are permitted substitutions when circuit design allows tighter tolerance grades. Feature differences (anti-sulfur vs moisture resistant) and manufacturer variations (YAGEO vs Stackpole) do not prevent substitution when core electrical and mechanical parameters align.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts maintain identical electrical and mechanical specifications required for direct PCB replacement of the AF2010JK-07300RL. Selection between alternatives should be based on the following factors:

RC2010FK-07300RL (YAGEO): Tighter tolerance grade (±1%) provides improved accuracy for precision circuits. Moisture-resistant feature replaces anti-sulfur coating. Maintains YAGEO manufacturer continuity with higher inventory availability (3800 pcs).

RC2010JK-07300RL (YAGEO): Identical tolerance (±5%) and package as the main part. Moisture-resistant feature differs from anti-sulfur specification. Same manufacturer with highest inventory availability (4034 pcs).

RMCF2010FT300R (Stackpole Electronics Inc): Tighter tolerance grade (±1%) with automotive AEC-Q200 qualification matching the main part's automotive rating. Alternative manufacturer source with highest inventory availability (4795 pcs). Marginal height difference (0.028" vs 0.026") remains within standard PCB assembly tolerances.

All parts are active products with unlimited moisture sensitivity rating and full RoHS3 compliance.

Frequently Asked Questions (FAQ)

Q: Can RC2010FK-07300RL replace AF2010JK-07300RL directly on the PCB?

A: Yes. Both parts share identical 2010 (5025 Metric) package dimensions, 2-termination configuration, and electrical specifications (300 Ohms, 0.75W, -55°C ~ 155°C operating range). The tolerance upgrade from ±5% to ±1% is a compatible enhancement.

Q: What is the difference between anti-sulfur and moisture-resistant features?

A: Anti-sulfur coating (AF2010JK-07300RL) protects against sulfur contamination in specific environments. Moisture-resistant coating (RC2010FK-07300RL, RC2010JK-07300RL) provides protection against humidity. Both are thick film resistor protective measures. Feature selection depends on application environment requirements.

Q: Is RMCF2010FT300R from Stackpole Electronics compatible with YAGEO parts?

A: Yes. RMCF2010FT300R meets all electrical and mechanical compatibility requirements. The 0.002" height difference (0.028" vs 0.026" maximum seated height) is within standard PCB assembly tolerances and does not affect functionality or placement.

Q: Can I use ±1% tolerance parts where ±5% is specified?

A: Yes. Tighter tolerance grades are compatible substitutions. RC2010FK-07300RL and RMCF2010FT300R both offer ±1% tolerance and can replace the ±5% specification without circuit redesign.

Q: Are all substitute parts automotive-qualified?

A: AF2010JK-07300RL and RMCF2010FT300R carry AEC-Q200 automotive qualification. RC2010FK-07300RL and RC2010JK-07300RL do not list AEC-Q200 rating. For automotive applications requiring AEC-Q200 compliance, use AF2010JK-07300RL or RMCF2010FT300R.

Q: What inventory considerations apply to these substitutes?

A: RMCF2010FT300R has the highest availability (4795 pcs), followed by RC2010JK-07300RL (4034 pcs) and RC2010FK-07300RL (3800 pcs). The main part AF2010JK-07300RL has lower availability (1180 pcs). All parts are active products in production.
