Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict alignment of the following parameters:

Primary Electrical Criteria:

• Resistance value: 187 Ohms
• Tolerance: ±1%
• Power rating: 0.125W (1/8W)
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C

Mechanical Criteria:

• Package type: 0805 (2012 Metric)
• Composition: Thick Film
• Number of terminations: 2
• Physical dimensions: 0.079" L x 0.049" W (2.00mm x 1.25mm)

Compliance Criteria:

• RoHS3 compliance
• MSL rating: 1 (Unlimited)
• REACH status: REACH Unaffected

Substitute parts are classified as Direct or Similar based on feature alignment. Direct substitutes maintain identical or superior specifications across all parameters. Similar substitutes may include enhanced features (automotive AEC-Q200 qualification, high voltage capability) or minor dimensional variations that do not affect circuit performance.

Parameter Comparison

Engineering Selection Recommendations

Direct Substitutes (Equivalent Replacement):

ERJ-6ENF1870V, KTR10EZPF1870, RC0805FR-07187RL, and RMCF0805FT187R are direct substitutes for RC2012F1870CS. All maintain identical electrical specifications (187 Ohms ±1%, 0.125W, ±100ppm/°C, -55°C to 155°C operating range) and 0805 package format. These parts are Active product status with RoHS3 compliance and MSL 1 rating. Height variations (0.60mm to 0.70mm) remain within acceptable PCB assembly tolerances and do not affect circuit functionality.

Similar Substitutes (Enhanced Features):

CRCW0805187RFKEA from Vishay Dale is a similar substitute offering automotive AEC-Q200 qualification with the lowest seated height (0.50mm). This part is suitable for applications requiring automotive-grade reliability without functional modification to the original design.

Discontinued Part:

MCR10ERTF1870 is discontinued at DiGi Electronics. Direct substitutes from the comparison table are recommended for new designs or component replenishment.

Packaging Consideration:

RC2012F1870CS is supplied in Tape & Reel (TR) packaging. MCR10ERTF1870 is supplied in Cut Tape (CT) & Digi-Reel® format. For automated assembly processes requiring continuous reel supply, TR-packaged alternatives are preferred.

Frequently Asked Questions (FAQ)

Q: Can ERJ-6ENF1870V replace RC2012F1870CS in non-automotive applications?

A: Yes. ERJ-6ENF1870V meets all electrical and mechanical specifications of RC2012F1870CS. The automotive AEC-Q200 qualification is an additional feature that does not restrict use in standard industrial or consumer applications. All compliance certifications (RoHS3, MSL 1) are equivalent.

Q: What is the significance of the height difference between substitute parts?

A: Height variations (0.50mm to 0.70mm) are within standard PCB assembly tolerances. These differences do not affect electrical performance or circuit functionality. Component placement and reflow soldering processes accommodate these dimensional ranges without modification.

Q: Is KTR10EZPF1870 suitable for high-voltage applications?

A: KTR10EZPF1870 includes high-voltage capability as a specified feature. However, the electrical specifications (187 Ohms ±1%, 0.125W) remain identical to RC2012F1870CS. High-voltage qualification indicates enhanced design margins; it does not change the component's resistance or power rating.

Q: Why is MCR10ERTF1870 listed as discontinued?

A: MCR10ERTF1870 is discontinued at DiGi Electronics. For new designs or inventory replenishment, direct substitutes (ERJ-6ENF1870V, KTR10EZPF1870, RC0805FR-07187RL, RMCF0805FT187R) are recommended. All alternatives maintain identical electrical specifications and 0805 package format.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed in the parameter comparison table are RoHS3 compliant with MSL 1 (Unlimited) moisture sensitivity level, matching the compliance profile of RC2012F1870CS.

Q: What packaging formats are available for substitute parts?

A: RC2012F1870CS, ERJ-6ENF1870V, KTR10EZPF1870, RC0805FR-07187RL, RMCF0805FT187R, and CRCW0805187RFKEA are supplied in Tape & Reel (TR) format suitable for automated assembly. MCR10ERTF1870 is supplied in Cut Tape (CT) & Digi-Reel® format. TR packaging is standard for high-volume production environments.
