Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RR1220P-2941-D-M are qualified based on the following criteria:

Electrical Compatibility Requirements:

• Resistance value: 2.94 kOhms (exact match required)
• Tolerance: ±0.5% or better (lower tolerance values are acceptable upgrades)
• Power rating: 0.1W minimum (equal or higher ratings are acceptable)
• Composition: Thin film (maintains performance characteristics)
• Temperature coefficient: ±25ppm/°C or better
• Operating temperature range: Must support -55°C ~ 125°C minimum

Mechanical Compatibility Requirements:

• Package / Case: 0805 (2012 Metric) (exact match required)
• Footprint dimensions: 0.079" L x 0.049" W (2.00mm x 1.25mm) (exact match required)
• Number of terminations: 2 (exact match required)
• Height seated maximum: Physical clearance consideration for PCB assembly

Compliance & Environmental Requirements:

• RoHS3 compliance maintained
• Moisture sensitivity level: MSL 1 (unlimited) maintained
• ECCN and HTSUS classifications aligned

Substitute parts meeting all electrical and mechanical parameters are classified as direct equivalents. Parts with improved tolerance, higher power ratings, or automotive certifications are classified as upgrades while maintaining full compatibility.

Parameter Comparison

Engineering Selection Recommendations

Direct Electrical Equivalent (Same Tolerance & Power Rating):

RN73C2A2K94BTDF from TE Connectivity Passive Product maintains identical electrical specifications (2.94 kOhms ±0.1% at 0.1W) with improved temperature coefficient (±10ppm/°C versus ±25ppm/°C). This part is electrically compatible but carries RoHS non-compliant status, which may restrict use in regulated applications requiring ROHS3 compliance.

Upgrade with Improved Tolerance (±0.1% vs ±0.5%):

RG2012P-2941-B-T5 (Susumu), ERA-6AEB2941V (Panasonic), and RT0805BRD072K94L (YAGEO) all provide ±0.1% tolerance with 0.125W power rating and extended operating temperature to 155°C. RG2012P-2941-B-T5 and ERA-6AEB2941V include AEC-Q200 automotive certification. All three maintain ROHS3 compliance and identical package dimensions.

Upgrade with Enhanced Power Rating (0.25W vs 0.1W):

5-2176092-7 from TE Connectivity Passive Product provides 0.25W power rating with ±0.1% tolerance and extended operating temperature to 155°C. Physical height increases to 0.026" (0.65mm) maximum seated height. ROHS3 compliant with identical footprint dimensions.

Automotive-Grade Selection:

RG2012P-2941-B-T5 and ERA-6AEB2941V both carry AEC-Q200 automotive certification with ±0.1% tolerance, 0.125W power rating, and extended temperature range to 155°C. Both maintain ROHS3 compliance and identical package footprint.

Compliance Consideration:

All substitute parts except RN73C2A2K94BTDF maintain ROHS3 compliance. Selection of RN73C2A2K94BTDF requires confirmation that RoHS non-compliance is acceptable for the application.

Frequently Asked Questions (FAQ)

Q: Can RG2012P-2941-B-T5 directly replace RR1220P-2941-D-M on the PCB?

A: Yes. Both parts use identical 0805 (2012 Metric) package with 0.079" L x 0.049" W footprint dimensions and 2-termination configuration. RG2012P-2941-B-T5 seated height is 0.020" (0.50mm) maximum, matching the original part. Electrical specifications are compatible with improved tolerance (±0.1% versus ±0.5%).

Q: What is the difference between the tolerance specifications?

A: The RR1220P-2941-D-M has ±0.5% tolerance, meaning the actual resistance value can vary by up to 0.5% from the nominal 2.94 kOhms specification. Substitute parts with ±0.1% tolerance provide tighter resistance accuracy, with variation limited to 0.1% from nominal. Lower tolerance values represent improved precision.

Q: Why does 5-2176092-7 have a higher seated height?

A: The 5-2176092-7 has 0.026" (0.65mm) maximum seated height compared to 0.020" (0.50mm) for the original part due to its higher 0.25W power rating. This increased height accommodates larger internal resistive elements. Verify PCB clearance before substitution.

Q: Are all substitute parts RoHS3 compliant?

A: Five of the six substitute parts are ROHS3 compliant. RN73C2A2K94BTDF is RoHS non-compliant. Confirm regulatory requirements for your application before selecting this part.

Q: What does AEC-Q200 certification mean?

A: AEC-Q200 is an automotive electronics qualification standard. RG2012P-2941-B-T5 and ERA-6AEB2941V carry this certification, indicating qualification for automotive applications with enhanced reliability testing and temperature cycling requirements.

Q: Can I use a substitute part with higher power rating in a circuit designed for 0.1W?

A: Yes. A higher power rating (0.125W or 0.25W) is acceptable in circuits designed for 0.1W operation. The component will operate within its power dissipation limits. However, verify that increased physical dimensions do not create PCB layout conflicts.

Q: What is the difference between Tape & Reel and Cut Tape packaging?

A: Tape & Reel (TR) packaging supplies components on continuous tape wound on reels, suitable for high-volume automated assembly. Cut Tape (CT) & Digi-Reel® packaging from ERA-6AEB2941V provides components on cut tape segments, typically for lower-volume or manual assembly operations. Both formats contain identical components.

Q: Which substitute part has the best temperature stability?

A: RN73C2A2K94BTDF has the lowest temperature coefficient at ±10ppm/°C compared to ±25ppm/°C for all other parts. This provides superior resistance stability across temperature variations. However, this part is RoHS non-compliant.

Q: Can I substitute ERA-6AEB2941V for RR1220P-2941-D-M in a medical device application?

A: ERA-6AEB2941V is electrically and mechanically compatible with identical 0805 package, 2.94 kOhms resistance, and improved ±0.1% tolerance. It maintains ROHS3 compliance and MSL 1 rating. Confirm that AEC-Q200 automotive certification meets medical device qualification requirements for your specific application.
