RMCS1206FT4R87 Equivalent & Substitute Parts

Part Overview

The RMCS1206FT4R87 is a 4.87 Ohm ±1% 0.25W chip resistor in 1206 (3216 Metric) package manufactured by Stackpole Electronics Inc. This thick film resistor features anti-sulfur composition and is designed for general-purpose applications requiring precision resistance values in compact surface-mount form factors. The part maintains Active product status with full RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Substitute parts are identified when original stock availability is limited or when equivalent electrical and mechanical specifications are required for production continuity.

Substitute Part Grouping Explanation

Substitution eligibility for the RMCS1206FT4R87 is determined by strict equivalence across the following critical parameters:

• Resistance value: 4.87 Ohms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.25W (exact match required)
• Package: 1206 (3216 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Temperature coefficient: ±200ppm/°C (exact match required)
• Operating temperature range: -55°C to 155°C (exact match required)
• RoHS3 compliance (required)
• MSL rating: 1 (Unlimited) (required)

The RC1206FR-074R87L from YAGEO meets all substitution criteria with identical electrical specifications and package dimensions. Both parts are Active status products with full regulatory compliance.

Parameter Comparison

Engineering Selection Recommendations

Both the RMCS1206FT4R87 and RC1206FR-074R87L are Active status products with identical electrical and mechanical specifications. Selection between these parts is based on availability and supply chain requirements rather than technical differentiation. The RC1206FR-074R87L from YAGEO offers higher inventory availability (4625 pcs) compared to the Stackpole original (875 pcs). Both parts satisfy RoHS3 compliance, REACH unaffected status, and EAR99 export classification requirements. The dimensional compatibility (3.10mm × 1.55mm to 1.60mm width variation) and identical height (0.65mm maximum seated height) ensure direct PCB footprint compatibility without design modification.

Frequently Asked Questions (FAQ)

Q: Can RC1206FR-074R87L be used as a direct replacement for RMCS1206FT4R87?

A: Yes. Both parts share identical resistance (4.87 Ohms), tolerance (±1%), power rating (0.25W), package (1206), temperature coefficient (±200ppm/°C), and operating range (-55°C to 155°C). Electrical and mechanical compatibility is complete.

Q: Are there dimensional differences between these parts?

A: The length is identical at 3.10mm. Width varies slightly: RMCS1206FT4R87 is 1.55mm while RC1206FR-074R87L is 1.60mm. Both have identical maximum seated height of 0.65mm. These variations are within standard 1206 package tolerances and do not affect PCB footprint compatibility.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export purposes. Both carry HTSUS code 8533.21.0030 and MSL rating 1 (Unlimited).

Q: What is the difference between anti-sulfur and moisture-resistant compositions?

A: Both are thick film resistor compositions. Anti-sulfur formulation in the RMCS series provides protection against sulfur-containing environments. Moisture-resistant formulation in the RC_L series provides protection against humidity exposure. Both compositions support the same electrical specifications and operating temperature range for this application.

Q: Which part should be selected for new designs?

A: Selection is based on supply availability and procurement lead times. Both parts are functionally equivalent. The RC1206FR-074R87L offers higher stock availability, making it suitable for immediate procurement needs. The RMCS1206FT4R87 remains a valid choice where Stackpole supply chain preference exists.
