Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RN73H2ATTD2000B10 are qualified based on the following criteria:

Electrical Parameters (Must Match):

• Resistance value: 200 Ohms
• Power rating: 0.125W (1/8W)
• Operating temperature range: -55°C ~ 155°C
• Temperature coefficient: ±10ppm/°C

Mechanical Parameters (Must Match):

• Package / Case: 0805 (2012 Metric)
• Number of terminations: 2
• Physical dimensions: 0.079" L x 0.049" W (2.00mm x 1.25mm)

Compliance & Certification (Must Match):

• Automotive AEC-Q200 qualification
• ROHS3 compliance
• Moisture Sensitivity Level: 1 (Unlimited)

Allowable Variation:

• Tolerance: Substitute parts may have equal or tighter tolerance (±0.05% is acceptable as an upgrade from ±0.1%)
• Composition: Thin film substitutes are acceptable for metal film applications when all other parameters align
• Film technology: Anti-sulfur thin film construction is compatible with moisture-resistant metal film specifications

The substitute parts RG2012N-201-W-T1 and RG2012N-201-W-T5 (both Susumu manufacturer) meet all mandatory criteria with improved tolerance specification.

Parameter Comparison

Engineering Selection Recommendations

Primary Part: RN73H2ATTD2000B10

The KOA Speer Electronics RN73H2ATTD2000B10 is the specified component with active production status, ROHS3 compliance, and AEC-Q200 automotive qualification. This metal film resistor is suitable for applications requiring ±0.1% tolerance accuracy in automotive environments with unlimited moisture exposure tolerance.

Substitute Parts: RG2012N-201-W-T1 and RG2012N-201-W-T5

Both Susumu RG2012N-201-W-T1 and RG2012N-201-W-T5 resistors are direct substitutes with the following characteristics:

• Both maintain identical electrical specifications (200 Ohms, 0.125W, ±10ppm/°C, -55°C ~ 155°C)
• Both feature tighter tolerance (±0.05%) compared to the primary part (±0.1%)
• Both are AEC-Q200 qualified for automotive applications
• Both are ROHS3 compliant with MSL 1 rating
• Both use thin film anti-sulfur construction compatible with moisture-resistant specifications
• Both have reduced seated height (0.020" vs 0.024"), providing improved PCB clearance

The two Susumu substitutes differ only in packaging tape configuration (T1 vs T5 reel specifications), with no impact on component electrical or mechanical performance. Selection between RG2012N-201-W-T1 and RG2012N-201-W-T5 depends on procurement and assembly equipment compatibility.

Frequently Asked Questions (FAQ)

Q: Can RG2012N-201-W-T1 and RG2012N-201-W-T5 be used interchangeably with RN73H2ATTD2000B10?

A: Yes. Both Susumu parts meet all mandatory electrical, mechanical, and compliance requirements. The resistance value, power rating, temperature range, temperature coefficient, package dimensions, and automotive AEC-Q200 qualification are identical. The tighter tolerance (±0.05% vs ±0.1%) represents an upgrade in accuracy.

Q: What is the difference between RG2012N-201-W-T1 and RG2012N-201-W-T5?

A: Both parts are electrically and mechanically identical. The difference is in tape reel configuration (T1 vs T5), which affects packaging and handling during assembly. Component selection should be based on equipment compatibility and procurement specifications.

Q: Are the physical dimensions compatible for PCB assembly?

A: Yes. All three parts use the 0805 (2012 Metric) package with identical footprint dimensions (0.079" L x 0.049" W). The Susumu substitutes have slightly lower seated height (0.020" vs 0.024"), which provides additional PCB clearance and is not a compatibility issue.

Q: Do the substitute parts maintain automotive qualification?

A: Yes. Both RG2012N-201-W-T1 and RG2012N-201-W-T5 are AEC-Q200 qualified, meeting automotive reliability and performance standards equivalent to the primary part.

Q: What is the impact of thin film vs metal film composition?

A: Both thin film and metal film resistor technologies meet the specified electrical parameters for this application. The Susumu thin film construction with anti-sulfur treatment provides equivalent performance with enhanced tolerance accuracy (±0.05%) and is fully compatible with the original metal film specification.

Q: Are all parts ROHS3 compliant?

A: Yes. The primary part RN73H2ATTD2000B10 and both substitute parts RG2012N-201-W-T1 and RG2012N-201-W-T5 are ROHS3 compliant with REACH Unaffected status.
