Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AF1210JR-0782KL is determined by the following critical parameters:

• Resistance value: 82 kOhms (exact match required)
• Power rating: 0.5W minimum
• Package: 1210 (3225 Metric) form factor
• Composition: Thick film technology
• Operating temperature range: -55°C ~ 155°C minimum
• RoHS3 compliance
• MSL rating: 1 or better

The RC1210FR-0782KL qualifies as a direct substitute based on matching all critical electrical and mechanical parameters. The tolerance specification of ±1% on the substitute part represents an improvement over the ±5% tolerance of the primary part, while maintaining full compatibility with circuit requirements that accept the original tolerance.

Parameter Comparison

Engineering Selection Recommendations

Both the AF1210JR-0782KL and RC1210FR-0782KL are active production parts manufactured by YAGEO with full ROHS3 compliance and MSL 1 rating. Selection between these parts should be based on the following criteria:

The AF1210JR-0782KL is specified for applications requiring automotive AEC-Q200 qualification with anti-sulfur coating. This part is appropriate when the circuit design explicitly requires these automotive-grade features.

The RC1210FR-0782KL offers improved tolerance performance (±1% versus ±5%) with moisture-resistant characteristics. This substitute is suitable for applications where tighter tolerance control is beneficial and automotive-specific features are not mandatory. Both parts maintain identical electrical performance across the full operating temperature range and are mechanically interchangeable in 1210 package footprints.

Frequently Asked Questions (FAQ)

Q: Can RC1210FR-0782KL replace AF1210JR-0782KL in automotive applications?

A: The RC1210FR-0782KL is mechanically and electrically compatible with the AF1210JR-0782KL. However, the primary part carries explicit AEC-Q200 automotive qualification and anti-sulfur coating. Use the substitute only if your application does not require these specific automotive certifications.

Q: What is the difference in tolerance between these parts?

A: The AF1210JR-0782KL has ±5% tolerance, while the RC1210FR-0782KL has ±1% tolerance. The tighter tolerance of the substitute part provides better resistance value accuracy and is fully compatible with circuits designed for the original ±5% specification.

Q: Are the physical dimensions identical?

A: Yes. Both parts use the 1210 (3225 Metric) package with identical dimensions of 0.122" L x 0.102" W (3.10mm x 2.60mm) and maximum seated height of 0.024" (0.60mm). They are footprint-compatible for direct PCB substitution.

Q: What is the moisture sensitivity rating for both parts?

A: Both parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity limitations for storage or handling.

Q: Are both parts RoHS compliant?

A: Yes. Both the AF1210JR-0782KL and RC1210FR-0782KL are ROHS3 compliant and suitable for applications with RoHS requirements.
