RC1608J275CS Equivalent & Substitute Parts Reference

Part Overview

The RC1608J275CS is a 2.7 MOhms ±5% thick film chip resistor manufactured by Samsung Electro-Mechanics in 0603 (1608 Metric) package format. This component is rated for 0.1W (1/10W) power dissipation and operates across the temperature range of -55°C to 155°C. The part is ROHS3 compliant, moisture resistant, and classified as MSL 1 (Unlimited). Currently in active production status with 711 pieces available in inventory.

Equivalent and substitute parts are necessary when the primary manufacturer part becomes unavailable, when supply chain optimization is required, or when design specifications allow for upgraded performance characteristics such as improved tolerance or automotive-grade qualification.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC1608J275CS is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 2.7 MOhms
• Package / Case: 0603 (1608 Metric)
• Power rating: 0.1W (1/10W)
• Composition: Thick Film
• Operating temperature range: -55°C to 155°C
• RoHS compliance: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Allowable Variation Parameters:

• Tolerance: ±5% (direct equivalent) or ±1% (upgrade)
• Temperature coefficient: ±100ppm/°C or ±200ppm/°C
• Packaging format: Tape & Reel (TR) or Cut Tape (CT) & Digi-Reel®
• Additional features: Automotive AEC-Q200 qualification (upgrade only)

Substitute parts are categorized as either direct equivalents (matching tolerance and base specifications) or upgrades (improved tolerance and/or automotive qualification).

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent Substitutes (±5% Tolerance):

RC0603JR-072M7L (YAGEO) functions as a direct electrical and mechanical equivalent to the RC1608J275CS. Both components share identical resistance, tolerance, power rating, package format, and temperature operating range. The primary distinction is packaging format: YAGEO supplies in Cut Tape (CT) & Digi-Reel® format versus Samsung's Tape & Reel (TR) format. This substitute is appropriate for applications where tolerance specification and base performance characteristics are the primary selection criteria.

RMCF0603JT2M70 (Stackpole Electronics Inc) is a direct equivalent with automotive AEC-Q200 qualification. While maintaining ±5% tolerance and identical electrical specifications, this part includes automotive-grade reliability certification. The temperature coefficient specification is ±200ppm/°C compared to the primary part's ±100ppm/°C. This substitute is suitable for applications requiring automotive qualification without tolerance upgrade.

Upgrade Substitutes (±1% Tolerance):

KTR03EZPF2704 (Rohm Semiconductor) and RMCF0603FT2M70 (Stackpole Electronics Inc) both provide improved tolerance specification at ±1% while maintaining all other critical parameters. Both parts carry automotive AEC-Q200 qualification. KTR03EZPF2704 includes high voltage capability designation. These upgrades are appropriate for applications where tighter tolerance control is required or where automotive-grade reliability is mandated by design specification.

All substitute parts maintain ROHS3 compliance, MSL 1 rating, and the full -55°C to 155°C operating temperature range of the primary part.

Frequently Asked Questions (FAQ)

Q: Can RC0603JR-072M7L replace RC1608J275CS in production assembly?

A: Yes. RC0603JR-072M7L is a direct electrical and mechanical equivalent. Both components have identical resistance (2.7 MOhms), tolerance (±5%), power rating (0.1W), package format (0603), and operating temperature range (-55°C to 155°C). The packaging format differs (Cut Tape & Digi-Reel® versus Tape & Reel), which may affect assembly line compatibility depending on pick-and-place equipment configuration.

Q: What is the difference between direct equivalent and upgrade substitutes?

A: Direct equivalent substitutes (RC0603JR-072M7L, RMCF0603JT2M70) maintain the ±5% tolerance specification of the primary part. Upgrade substitutes (KTR03EZPF2704, RMCF0603FT2M70) provide improved ±1% tolerance specification. Upgrade parts also include automotive AEC-Q200 qualification, which is not present in the primary part or direct equivalents.

Q: Is automotive AEC-Q200 qualification required for the RC1608J275CS application?

A: Automotive AEC-Q200 qualification is not a requirement of the primary part specification. However, if your application requires automotive-grade reliability certification, RMCF0603JT2M70, KTR03EZPF2704, or RMCF0603FT2M70 are qualified alternatives.

Q: Does temperature coefficient variation affect substitution compatibility?

A: Temperature coefficient differences (±100ppm/°C versus ±200ppm/°C) do not prevent substitution at the component level. However, circuit-level performance may be affected in applications with stringent temperature stability requirements. RMCF0603JT2M70 and RMCF0603FT2M70 specify ±200ppm/°C, while RC1608J275CS, RC0603JR-072M7L, and KTR03EZPF2704 specify ±100ppm/°C.

Q: Can I use ±1% tolerance parts in place of ±5% tolerance specifications?

A: Yes. A ±1% tolerance part is a functional upgrade and can replace a ±5% tolerance specification. The tighter tolerance provides improved circuit performance and is backward compatible with designs specified for ±5% tolerance.

Q: What packaging considerations apply to these substitutes?

A: RC1608J275CS, RMCF0603JT2M70, KTR03EZPF2704, and RMCF0603FT2M70 are supplied in Tape & Reel (TR) format. RC0603JR-072M7L is supplied in Cut Tape (CT) & Digi-Reel® format. Verify that your assembly equipment supports the packaging format of the selected substitute part.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts (RC0603JR-072M7L, RMCF0603JT2M70, KTR03EZPF2704, RMCF0603FT2M70) are ROHS3 compliant and maintain MSL 1 (Unlimited) moisture sensitivity rating, matching the primary part specification.
