RP2012S-270-F Equivalent & Substitute Parts

Part Overview

The RP2012S-270-F is a 27 Ohms ±1% metal film chip resistor rated at 0.333W (1/3W) in 0805 (2012 Metric) surface mount package. This component is manufactured by Susumu and is classified as obsolete product status. The part is ROHS3 compliant with unlimited moisture sensitivity level (MSL 1) and operates across the temperature range of -55°C to 125°C. Due to its obsolete status, identifying equivalent substitute parts with matching electrical and mechanical specifications is necessary for ongoing design support and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the RP2012S-270-F is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Resistance value: 27 Ohms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.333W / 1/3W (exact match required)
• Temperature coefficient: 0 / +200ppm/°C (exact match required)
• Operating temperature range: -55°C ~ 125°C (exact match required)

Mechanical Parameters:

• Package / Case: 0805 (2012 Metric) (exact match required)
• Physical dimensions: 0.079" L x 0.049" W (2.00mm x 1.25mm) (exact match required)
• Height - Seated (Max): 0.020" (0.50mm) (exact match required)
• Number of terminations: 2 (exact match required)

Compliance Parameters:

• RoHS Status: ROHS3 Compliant (exact match required)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)

The substitute part RL1220S-270-F meets all critical electrical and mechanical parameters. The primary difference is composition (Thin Film with Current Sense feature versus Metal Film), which does not preclude substitution when the electrical specifications and package dimensions are identical.

Parameter Comparison

Engineering Selection Recommendations

The RL1220S-270-F is a direct substitute for the RP2012S-270-F based on electrical and mechanical parameter equivalence. Both parts are manufactured by Susumu and maintain identical resistance, tolerance, power rating, temperature coefficient, operating temperature range, package dimensions, and compliance certifications.

The RL1220S-270-F carries Active product status, providing supply continuity and long-term availability compared to the obsolete RP2012S-270-F. Both parts are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity rating, ensuring compatibility with standard manufacturing and storage processes.

The composition difference (Thin Film with Current Sense feature in the substitute versus Metal Film in the original) does not affect substitution eligibility when all electrical specifications and mechanical parameters are identical. The substitute part is available in Tape & Reel (TR) packaging format, supporting automated assembly processes.

Frequently Asked Questions (FAQ)

Q: Can the RL1220S-270-F replace the RP2012S-270-F in existing designs?

A: Yes. The RL1220S-270-F meets all critical electrical parameters (27 Ohms ±1%, 0.333W, 0 / +200ppm/°C, -55°C ~ 125°C) and mechanical specifications (0805 package, 2.00mm x 1.25mm dimensions, 0.50mm max height). Both parts are ROHS3 compliant with MSL 1 rating.

Q: What is the difference between Metal Film and Thin Film composition?

A: Both compositions are resistive film technologies. The provided specifications indicate the RL1220S-270-F includes a Current Sense feature. When electrical specifications and package parameters are identical, both compositions are functionally equivalent for the specified application.

Q: Are there packaging differences between these parts?

A: The RP2012S-270-F is supplied in standard packaging format. The RL1220S-270-F is supplied in Tape & Reel (TR) format, which is standard for automated surface mount assembly. Both parts use the same 0805 (2012 Metric) package and have identical physical dimensions.

Q: Is the RL1220S-270-F available in higher quantities?

A: Yes. The RL1220S-270-F has 3010 Pcs in stock compared to 874 Pcs for the RP2012S-270-F, and carries Active product status, ensuring ongoing availability.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the RP2012S-270-F and RL1220S-270-F are ROHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity level. Both are classified under ECCN EAR99.
