Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RC1005F7871CS are classified based on strict electrical and mechanical parameter alignment. The primary substitution criteria are:

Critical Parameters (Must Match Exactly):

• Resistance value: 7.87 kOhms
• Tolerance: ±1%
• Package / Case: 0402 (1005 Metric)
• Composition: Thick Film
• Temperature Coefficient: ±100 ppm/°C
• Operating Temperature Range: -55°C to 155°C
• Terminations: 2
• RoHS Status: ROHS3 Compliant
• MSL Rating: 1 (Unlimited)

Allowable Variation Parameters:

• Power Rating: 0.063W (1/16W) or higher rated alternatives
• Packaging format: Tape & Reel (TR) or Cut Tape (CT) & Digi-Reel®
• Features: Moisture Resistant designation optional; Automotive AEC-Q200 certification optional

Substitute parts meeting all critical parameters are classified as Direct equivalents. Parts with identical electrical specifications but enhanced power ratings or automotive certifications are classified as Upgrade or Similar alternatives, provided all other parameters remain within specification.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent (Preferred for Drop-In Replacement):

CR0402-FX-7871GLF (Bourns Inc.) provides direct electrical and mechanical equivalence to RC1005F7871CS with identical power rating and package specifications. This part is suitable for applications requiring straightforward component substitution without design modification.

Direct Equivalent with Moisture Resistance:

RC0402FR-077K87L (YAGEO) matches all electrical parameters and includes moisture resistant construction identical to the primary part. This option is preferred when moisture resistance is a specified design requirement.

Upgrade Alternative (Enhanced Power Rating):

ERJ-2RKF7871X (Panasonic Electronic Components) provides identical electrical specifications with increased power rating of 0.1W (1/10W) versus 0.063W (1/16W). This part includes Automotive AEC-Q200 certification. Selection of this upgrade is appropriate for applications requiring higher thermal margin or automotive qualification.

Similar Alternatives (Automotive Qualified):

AC0402FR-077K87L (YAGEO), CRCW04027K87FKED (Vishay Dale), and RMCF0402FT7K87 (Stackpole Electronics Inc) all meet base electrical specifications with Automotive AEC-Q200 certification. AC0402FR-077K87L additionally includes moisture resistant construction. These parts are suitable for automotive applications or designs requiring AEC-Q200 compliance.

Selection among substitute parts should be based on application requirements for automotive qualification, moisture resistance, power margin, and packaging format availability.

Frequently Asked Questions (FAQ)

Q: Can RC0402FR-077K87L replace RC1005F7871CS in any application?

A: RC0402FR-077K87L is a direct equivalent with identical electrical specifications (7.87 kOhms ±1%, 0.063W, 0402 package) and includes moisture resistant construction matching the primary part. It is suitable for direct substitution in all applications where RC1005F7871CS is specified.

Q: What is the difference between the 0.063W and 0.1W power ratings?

A: ERJ-2RKF7871X is rated at 0.1W (1/10W) compared to RC1005F7871CS at 0.063W (1/16W). The higher power rating provides increased thermal margin and allows operation at higher power dissipation levels. This part is suitable for applications requiring enhanced power handling capability while maintaining identical resistance and tolerance specifications.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity level, matching the environmental and regulatory status of RC1005F7871CS.

Q: What does AEC-Q200 certification indicate?

A: AEC-Q200 is an automotive qualification standard. Parts bearing this certification (ERJ-2RKF7871X, AC0402FR-077K87L, CRCW04027K87FKED, RMCF0402FT7K87) have been qualified for automotive applications and meet specified reliability and performance requirements for automotive environments. Selection of AEC-Q200 certified parts is required for automotive applications.

Q: Can I use CR0402-FX-7871GLF if moisture resistance is required?

A: CR0402-FX-7871GLF does not specify moisture resistant construction. For applications requiring moisture resistance, select RC0402FR-077K87L or AC0402FR-077K87L, both of which include moisture resistant thick film construction.

Q: Are there packaging format differences among substitute parts?

A: RC1005F7871CS and most substitutes are supplied in Tape & Reel (TR) format. RC0402FR-077K87L is available in Cut Tape (CT) & Digi-Reel® format. Verify packaging format compatibility with assembly equipment and procurement requirements before selection.

Q: What is the temperature coefficient specification and why does it matter?

A: All listed parts maintain ±100 ppm/°C temperature coefficient across the -55°C to 155°C operating range. This specification indicates the resistor's resistance change per degree Celsius. Identical temperature coefficients ensure equivalent performance across temperature variations in the specified operating range.
