RR1220P-274-B-T5 Equivalent & Substitute Parts

Part Overview

The RR1220P-274-B-T5 is a 270 kOhms ±0.1% thin film chip resistor manufactured by Susumu in 0805 (2012 Metric) package format with 0.1W power rating. This component is classified as obsolete product status. Due to obsolescence and limited availability relative to active alternatives, equivalent substitute parts from active product lines are available to maintain design continuity and ensure long-term supply chain reliability.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RR1220P-274-B-T5 is determined by the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 270 kOhms
• Tolerance: ±0.1%
• Package / Case: 0805 (2012 Metric)
• Composition: Thin Film
• Temperature Coefficient: ±25ppm/°C
• Number of Terminations: 2
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: MSL 1

Allowable Variation Parameters:

• Power Rating: Substitute parts with equal or higher power ratings (0.1W or greater) are acceptable
• Operating Temperature Range: Substitute parts with equal or extended upper temperature limits are acceptable
• Product Status: Active product status substitutes are preferred over obsolete status

All substitute parts listed meet or exceed the mandatory matching parameters and maintain full electrical and mechanical compatibility with the original RR1220P-274-B-T5 specification.

Parameter Comparison

Engineering Selection Recommendations

RG2012P-274-B-T5 (Susumu): Direct manufacturer alternative with active product status. Identical resistance, tolerance, and temperature coefficient. Higher power rating (0.125W vs. 0.1W) and extended operating temperature range (-55°C ~ 155°C). Includes anti-sulfur and automotive AEC-Q200 qualification. Identical physical dimensions and seated height. Recommended for applications requiring enhanced reliability and automotive compliance.

CPF0805B270KE1 (TE Connectivity Passive Product): Active product from established manufacturer. Matches original power rating (0.1W) and all electrical specifications. Extended operating temperature range (-55°C ~ 155°C). Slightly increased seated height (0.026" vs. 0.020"). Suitable for general-purpose applications requiring active product status and TE Connectivity supply chain support.

ERA-6AEB274V (Panasonic Electronic Components): Active product with automotive AEC-Q200 qualification. Higher power rating (0.125W) and extended operating temperature range (-55°C ~ 155°C). Includes anti-sulfur feature. Seated height 0.024". Recommended for automotive and high-reliability applications.

RT0805BRD07270KL (YAGEO): Active product from major resistor manufacturer. Higher power rating (0.125W) and extended operating temperature range (-55°C ~ 155°C). Seated height 0.024". Suitable for cost-optimized designs requiring active product availability.

Frequently Asked Questions (FAQ)

Q: Can RG2012P-274-B-T5 directly replace RR1220P-274-B-T5 in existing designs?

A: Yes. RG2012P-274-B-T5 maintains identical resistance (270 kOhms), tolerance (±0.1%), package (0805), composition (thin film), and temperature coefficient (±25ppm/°C). The higher power rating (0.125W vs. 0.1W) and extended operating temperature range provide enhanced performance margins. Physical dimensions and seated height are identical.

Q: What is the difference between 0.1W and 0.125W power ratings?

A: Power rating indicates maximum continuous power dissipation. A 0.125W (1/8W) rated resistor can safely dissipate 25% more power than a 0.1W (1/10W) rated resistor. Substituting a higher-rated component is acceptable and provides additional thermal margin. Substituting a lower-rated component is not acceptable.

Q: Are all substitute parts automotive qualified?

A: RG2012P-274-B-T5 and ERA-6AEB274V carry AEC-Q200 automotive qualification. CPF0805B270KE1 and RT0805BRD07270KL do not list automotive qualification. For automotive applications, RG2012P-274-B-T5 or ERA-6AEB274V are appropriate selections.

Q: Does the seated height difference affect PCB layout?

A: CPF0805B270KE1 has maximum seated height of 0.026" (0.65mm) compared to 0.020" (0.50mm) for the original part. ERA-6AEB274V and RT0805BRD07270KL have 0.024" (0.60mm) seated height. These differences are within typical PCB assembly tolerances for 0805 components. Verify clearance requirements for specific applications with restricted vertical space.

Q: What is the significance of MSL 1 rating?

A: Moisture Sensitivity Level 1 (Unlimited) indicates the component has unlimited shelf life and requires no special moisture control during storage or handling. All listed substitute parts carry MSL 1 rating, ensuring identical moisture management requirements.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts listed are ROHS3 compliant, matching the original RR1220P-274-B-T5 compliance status.

Q: Which substitute offers the best long-term availability?

A: ERA-6AEB274V (Panasonic) shows highest current inventory (24,352 pcs) and active product status. RG2012P-274-B-T5 (Susumi) and RT0805BRD07270KL (YAGEO) also maintain active status with substantial inventory levels. All three are suitable for long-term supply chain planning.
