CPF1206B261KE1 Equivalent & Substitute Parts

Part Overview

The CPF1206B261KE1 is a 261 kOhms ±0.1% thin film chip resistor manufactured by TE Connectivity Passive Product in the 1206 (3216 Metric) package format. This surface-mount device is rated for 0.125W (1/8W) power dissipation with a temperature coefficient of ±25ppm/°C and operates across the -55°C to 155°C temperature range. The component is RoHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating and is currently in active production status. Equivalent and substitute parts are identified to provide design flexibility, accommodate supply chain variations, and support applications requiring alternative power ratings or automotive-grade certifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CPF1206B261KE1 is determined by the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 261 kOhms
• Tolerance: ±0.1%
• Composition: Thin Film
• Package: 1206 (3216 Metric)
• Temperature Coefficient: ±25ppm/°C
• Operating Temperature Range: -55°C to 155°C
• RoHS3 Compliance
• MSL Rating: 1 (Unlimited)

Allowable Variation Parameters:

• Power Rating: Substitute parts may have equal or higher power ratings (0.125W or greater)
• Physical Dimensions: Minor variations within 1206 package specification tolerance
• Manufacturer: Different manufacturers permitted if all electrical and environmental specifications are met
• Certifications: Additional certifications (such as AEC-Q200) are permissible

The identified substitute parts ERA-8AEB2613V and RT1206BRD07261KL meet all mandatory parameters and provide upgraded power ratings of 0.25W (1/4W), making them suitable for applications requiring higher power dissipation capability within the same package footprint.

Parameter Comparison

Engineering Selection Recommendations

CPF1206B261KE1 (TE Connectivity Passive Product): Select this part for applications where the 0.125W power rating is sufficient and TE Connectivity supply chain preference is established. RoHS3 compliance and MSL 1 rating support standard commercial and industrial applications across the full -55°C to 155°C operating range.

ERA-8AEB2613V (Panasonic Electronic Components): Select this part for automotive applications requiring AEC-Q200 qualification or when higher power dissipation (0.25W) is needed within the same package footprint. REACH Unaffected status provides additional regulatory clarity. The upgraded power rating accommodates designs with higher current or thermal stress conditions.

RT1206BRD07261KL (YAGEO): Select this part when YAGEO supply chain preference is established or when the 0.25W power rating upgrade is required for non-automotive applications. REACH Unaffected status and RoHS3 compliance support standard commercial and industrial deployment. Physical dimensions (3.10mm L x 1.60mm W) remain within 1206 package specification.

All three parts are active production components with established inventory availability and are electrically and mechanically interchangeable within the specified parameter constraints.

Frequently Asked Questions (FAQ)

Q: Can ERA-8AEB2613V or RT1206BRD07261KL be used as direct replacements for CPF1206B261KE1?

A: Yes. Both substitute parts match the mandatory electrical parameters (261 kOhms ±0.1%, thin film composition, ±25ppm/°C temperature coefficient, -55°C to 155°C operating range) and package specification (1206 / 3216 Metric). The higher power ratings (0.25W versus 0.125W) represent an upgrade that does not compromise compatibility. Physical dimensions remain within 1206 package tolerance.

Q: What is the primary difference between the three parts?

A: The primary difference is power rating and certifications. CPF1206B261KE1 is rated for 0.125W, while ERA-8AEB2613V and RT1206BRD07261KL are rated for 0.25W. ERA-8AEB2613V includes AEC-Q200 automotive qualification; the other two parts do not specify automotive certification.

Q: Are there any dimensional incompatibilities between these parts?

A: No. All three parts conform to the 1206 (3216 Metric) package specification. Measured dimensions vary slightly (CPF1206B261KE1: 3.05mm L x 1.55mm W; ERA-8AEB2613V: 3.20mm L x 1.60mm W; RT1206BRD07261KL: 3.10mm L x 1.60mm W) but remain within standard 1206 package tolerance and are compatible with standard 1206 PCB footprints.

Q: Which part should be selected for automotive applications?

A: ERA-8AEB2613V is the appropriate selection for automotive applications due to AEC-Q200 qualification. This certification confirms compliance with automotive reliability and quality standards.

Q: Can the lower-power CPF1206B261KE1 be substituted with a higher-power part?

A: Yes. Substituting a 0.125W part with a 0.25W part is a valid upgrade that increases thermal margin and power dissipation capability. The higher-rated part will perform the same electrical function with improved reliability under thermal stress.

Q: Are all three parts RoHS3 compliant?

A: Yes. CPF1206B261KE1, ERA-8AEB2613V, and RT1206BRD07261KL are all RoHS3 compliant. ERA-8AEB2613V and RT1206BRD07261KL have confirmed REACH Unaffected status; CPF1206B261KE1 lists REACH status as Vendor Undefined.

Q: What is the MSL rating for these parts?

A: All three parts carry MSL 1 (Unlimited) rating, indicating unlimited shelf life and no moisture sensitivity restrictions for storage and handling.
