Substitute Part Grouping Explanation

The RC1210JR-072ML qualifies as a direct electrical and mechanical substitute for the AF1210JR-072ML based on the following matching parameters:

• Identical resistance value: 2 MOhms
• Identical tolerance: ±5%
• Identical power rating: 0.5W (1/2W)
• Identical package: 1210 (3225 Metric)
• Identical composition: Thick Film
• Identical temperature coefficient: ±100ppm/°C
• Identical operating temperature range: -55°C to 155°C
• Identical physical dimensions: 0.122" L x 0.102" W (3.10mm x 2.60mm)
• Identical height: 0.024" (0.60mm) maximum seated
• Identical termination count: 2
• Identical RoHS compliance: ROHS3 Compliant
• Identical MSL rating: 1 (Unlimited)

The primary distinction is the feature set: AF1210JR-072ML includes anti-sulfur and AEC-Q200 automotive qualification, while RC1210JR-072ML features moisture-resistant thick film construction. Both parts maintain identical electrical performance and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The RC1210JR-072ML provides moisture-resistant thick film construction with significantly higher inventory availability (10713 pieces versus 983 pieces). Both parts maintain identical resistance, tolerance, power rating, temperature performance, and physical footprint, ensuring direct PCB compatibility and circuit performance equivalence.

Frequently Asked Questions (FAQ)

Q: Can RC1210JR-072ML be used as a direct replacement for AF1210JR-072ML in automotive applications?

A: RC1210JR-072ML matches all electrical and mechanical parameters of AF1210JR-072ML. However, AF1210JR-072ML carries explicit AEC-Q200 automotive qualification. Selection depends on whether your application requires AEC-Q200 certification as a mandatory requirement.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both parts use the 1210 (3225 Metric) package with identical dimensions of 3.10mm length x 2.60mm width and 0.60mm maximum seated height. PCB footprints are interchangeable.

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

A: AF1210JR-072ML includes anti-sulfur protection, a feature for environments with sulfur contamination. RC1210JR-072ML features moisture-resistant thick film construction. Both parts maintain MSL rating 1 (Unlimited), indicating equivalent moisture handling capability.

Q: Do these parts have identical electrical performance?

A: Yes. Both parts specify 2 MOhms ±5% resistance, 0.5W power rating, ±100ppm/°C temperature coefficient, and -55°C to 155°C operating range. Electrical performance is equivalent.

Q: Which part should I select for new designs?

A: Selection is based on compliance requirements and supply availability. If AEC-Q200 automotive qualification is mandatory, specify AF1210JR-072ML. If moisture resistance is the primary concern and AEC-Q200 is not required, RC1210JR-072ML offers superior inventory availability.
