Substitute Part Grouping Explanation

Substitution of the TE Connectivity 1-1614911-0 is determined by the following critical parameters:

Mandatory Matching Parameters:

Resistance value: 27 kOhms
Tolerance: ±0.1% (minimum requirement)
Package / Case: 0805 (2012 Metric)
Composition: Thin Film
Operating temperature range: -55°C ~ 155°C (minimum)
Moisture Sensitivity Level: 1 (Unlimited)

Allowable Variations:

Power rating: Substitute parts rated at 0.125W (1/8W) or higher are acceptable as they provide equal or greater power dissipation capability
Temperature coefficient: Substitute parts with ±10ppm/°C, ±15ppm/°C, or ±25ppm/°C are acceptable
Product features: Anti-sulfur, automotive AEC-Q200, and moisture-resistant features are enhancements that do not prevent substitution
Product status: Active status substitutes are preferred over obsolete parts

Substitute parts are grouped into two categories: Upgrade substitutes (active status with enhanced features) and Direct substitutes (functionally equivalent with active status).

Engineering Selection Recommendations

Primary Upgrade Path (Same Manufacturer): CPF-A-0805B27KE and CPF-A-0805B27KE1 are direct upgrades from the obsolete 1-1614911-0. Both parts maintain identical electrical specifications (27 kOhms ±0.1%, 0.1W, ±25ppm/°C, -55°C ~ 155°C) while offering active product status and enhanced features including anti-sulfur coating, automotive AEC-Q200 qualification, and moisture resistance. These parts are recommended for direct replacement in existing designs.

Alternative Active Substitutes (Higher Power Rating): All remaining substitute parts feature 0.125W (1/8W) power rating, which exceeds the original 0.1W specification. These parts are electrically and mechanically compatible with the 0805 package and maintain the required 27 kOhms ±0.1% resistance value.

Panasonic ERA-6A Series (ERA-6AEB273V, ERA-6APB273V, ERA-6ARB273V, ERA-6ARW273V): All parts carry AEC-Q200 automotive qualification and operate across the full -55°C ~ 155°C temperature range. ERA-6ARW273V offers enhanced tolerance of ±0.05%. Temperature coefficient varies from ±10ppm/°C to ±25ppm/°C depending on part number.
Vishay MCU Series (MCU08050F2702BP100, MCU08050D2702BP500): Both parts feature anti-sulfur thin film construction and active product status. Operating temperature range is -55°C ~ 125°C. Temperature coefficient is ±10ppm/°C (MCU08050F2702BP100) or ±25ppm/°C (MCU08050D2702BP500).
Bourns CRT Series (CRT0805-BY-2702ELF): Current sense thin film resistor with 0.125W rating, ±25ppm/°C temperature coefficient, and full -55°C ~ 155°C operating range.

Frequently Asked Questions (FAQ)

Q: Can I use a 0.125W (1/8W) rated resistor as a substitute for the 0.1W (1/10W) original part?

A: Yes. The 0.125W rating provides greater power dissipation capability than the original 0.1W specification. A higher power rating does not create compatibility issues in applications designed for the lower rating. The physical dimensions remain identical in the 0805 package.

Q: Are all substitute parts compatible with the 0805 package footprint?

A: Yes. All substitute parts listed use the 0805 (2012 Metric) package with identical dimensions of 0.079" L x 0.049" W (2.00mm x 1.25mm). Height variations exist (0.020" to 0.026" seated height maximum) but remain within standard PCB assembly tolerances.

Q: What is the difference between the CPF-A-0805B27KE and CPF-A-0805B27KE1 parts?

A: Both parts are electrically and mechanically identical with the same specifications. The difference is in REACH status documentation: CPF-A-0805B27KE lists REACH Unaffected status, while CPF-A-0805B27KE1 lists Vendor Undefined status. For applications requiring confirmed REACH compliance, CPF-A-0805B27KE is recommended.

Q: Why do some substitute parts have lower operating temperature maximums (-55°C ~ 125°C vs. -55°C ~ 155°C)?

A: Vishay MCU series parts (MCU08050F2702BP100 and MCU08050D2702BP500) specify a maximum operating temperature of 125°C. If your application requires operation at temperatures above 125°C, select substitute parts with -55°C ~ 155°C rating: CPF-A series, Panasonic ERA-6A series, Bourns CRT series, or Susumu RG series.

Q: What does AEC-Q200 qualification mean?

A: AEC-Q200 is an automotive electronics qualification standard. Parts carrying this rating have been tested and approved for automotive applications. If your design requires automotive-grade components, select from: CPF-A-0805B27KE, CPF-A-0805B27KE1, Panasonic ERA-6A series, or Susumu RG2012N-273-B-T5.

Q: Can I substitute a ±0.05% tolerance part (ERA-6ARW273V) for the original ±0.1% part?

A: Yes. The ±0.05% tolerance is tighter (more precise) than the original ±0.1% specification. A tighter tolerance does not create compatibility issues and may improve circuit performance in precision applications. The part is fully substitutable.

Q: What is the difference between anti-sulfur and standard thin film resistors?

A: Anti-sulfur thin film resistors include protective coatings that resist sulfur contamination in industrial environments. Standard thin film resistors lack this protection. Both types are functionally equivalent in non-corrosive environments. Select anti-sulfur variants (Vishay MCU series, Panasonic ERA-6A series, Susumu RG series) for applications exposed to sulfur-containing atmospheres.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed carry RoHS3 Compliant status, ensuring compliance with Restriction of Hazardous Substances regulations.

Q: What does Moisture Sensitivity Level 1 (Unlimited) mean?

A: MSL 1 (Unlimited) indicates the component has no moisture sensitivity restrictions. These parts do not require special moisture-controlled storage or handling procedures and can be stored under standard conditions indefinitely.
